How Can I Brighten Dim Solar Lights?
How Can I Brighten Dim Solar Lights?
Hi, Do not forget to clean the small solar panel from time to time. If you do not the batteries will not recharge properly.1. Can solar lights can be used at night on airport runways?Yes, with a batt. for nite,But i wouldnt trust a battery for too long. maybe for dead people?!2. how long does it take for batteries to charge in solar lights?3 = 4 hourss3. ok, let me make it clearer, what light can you use to charge solar lights? Besides the sun.?The point of solar cells is that sunlight is free. If you charge your batteries with any other light source, you will get less back than what you put in. It would make better sense to use the original light source when you need the light. Anyway, solar cells will charge your batteries on a cloudy day---just not as fast as a sunny day.4. How do you recharge the rechargeable batteries in solar lights?It is possible to do this but you have to see the time controlling5. Do all solar lights take time before they start to light?I have small solar lights in my front yard. They took about a day of FULL sun light (not overcast outside) to light up. I kept thinking they were broken. They would not stay lit all night either. They still do not . So they do take time.6. anyvone know about outdoor solar lights?They have what is called a Photoelectric Eye, which senses electromagnetic radiation TRANSLATION: LIGHT! When the Eye sees no light, then it turns on7. Outdoor solar lights not very bright why?Usually they only have one LED bulb in them, one LED bulb is not going to give off much light, and it depends on the reflector inside as well, more LEDs more light, and also there are different LEDs that give off different strengths of light8. how do solar lights work?The panel on top of light absorbs solar energy and convert it into power which will be instored in batteris during daytime; at night, the battery will charge the LED light for work9. Why has one of my solar lights flipped to come on in daytime?there is a little photo electric eye probably on the top - make sure it is not covered with dirt or anything else... might look like a small round hole or a little domed button... check the lights that work to find it and see if something is different on the 'bad' light. If you can not find anything, the light sensor (electric eye) may have shorted out10. 10 ways to brighten up your garden in winterWith a little imagination and creativity, it's easy to add interest to your garden in the winter months. For the greatest impact, concentrate efforts on a few key areas that you see on a daily basis. These might include beds and pots close to the house, as well as the front garden, which you walk through every day. We've rounded up some of the best ideas to inspire you. Many require little effort and some are great value for money too. So, whether you step outside or look from your window, embrace winter and enjoy your garden at every opportunity. Brighten it up with simple lighting In winter, we often come home in the dark and miss seeing the garden altogether. Outdoor lighting can bring it back into play and transform the view from windows that would otherwise be dark, reflective panes. Try a few tea lights in clear jam jars to add seasonal twinkle for special occasions and solar lights to provide a few hours of decorative light. Fairy lights are fun draped in a tree and there's a wide range of lighting kits on offer that are quick and easy to install. Be sure to switch lighting off before going to bed, to minimise disruption to wildlife. Even just one piece of evergreen topiary will add interest to a pot or bed and hold an area together in winter. Formal shapes such as balls, pyramids and cubes work well, but if you like a more relaxed style, then the trend for looser 'cloud-pruned' and organic topiary shapes may suit you. Box and yew are traditional plant choices, but other small-leaved evergreens, such as Ilex crenata, phillyrea, Lonicera nitida and privet, clip well. For instant impact, you can buy ready-made, but more costly, topiary - expect to pay around 25 for a 30cm box ball. There are many fabulous winter flowering shrubs that deliver rich fragrance, such as chimonanthus, daphnes, mahonias, sarcococca, and viburnums. If they are tucked away at the back of borders, they will get overlooked and be under-appreciated. Plant them instead where their delicious scents can readily be enjoyed, such as close to the back door, in the front garden or beside a regularly used path. Many of these shrubs are happy in pots, so can be moved to centre stage for winter, then shifted to a less prominent position over the summer. Pots are the best way to add a seasonal splash of colour just where you need it. Opt for plants that look good together, such as cyclamen, heathers, hellebores, pansies and variegated ivy. In a large pot, add a shrubby evergreen plant for a bit of backbone, such as a rosemary or sarcococca. At this time of year, all these plants are available in garden centres in small pots, making it easy to mix and match. Warm up with a fire pit or brazier To use your garden on winter evenings, you need to make it as warm and comfortable as possible. There are some great braziers and fire pits on the market these days, which are ready to go and can be placed on the patio for people to huddle around. Most of us spend more time indoors over winter, so it really pays to have attractive views from your windows. Without redesigning your garden, consider what you can tweak to improve the composition. It's amazing what a bit of seasonal rearranging can do. Think about relocating anything attractive that is readily moveable, such as pot displays and garden ornaments, so they can be clearly seen from the windows. Or remove a few of the lower branches of a tree to reveal a view of something eye-catching beyond. Get creative with flexible twigs and weave them into an eye-catching feature. You can buy long lengths of hazel or colourful willow by the bundle, or perhaps you have a plant that can be coppiced? Then bend, twist and weave the stems together to create interesting shapes. Simple woven twiggy balls look great dangling from trees, or make something large and abstract - a representation of an animal such as a deer or an oversized rabbit? Use galvanised wire to link sections together. They wo not last forever, but they are a great project for children. There's nothing better than a project that enhances the garden visually and benefits wildlife. Bug hotels can be simple or fancy, and of any size. Think nooks and crannies. Small holes make ideal hibernating homes for ladybirds and lacewings, so cut bamboo canes into short lengths with the hollow ends exposed. Set them into an old wooden box, or forget the frame and simply tie them into a small bundle. Leftover lengths of wood can be drilled with holes to do the same job, and if placed on the ground then beetle larvae will feed on the decaying dead wood. Perk things up with a splash of paint Introducing permanent colour into a garden through planting alone can be difficult, but painting or staining will add instant colour just where you need it to set off plantings or act as a backdrop. A wash of a water-based colour on large terracotta pots is not permanent, but will jazz things up for a few months. Rendered walls can be painted, while wooden fences and structures such as obelisks or pergolas are best stained, as it's easier to re-apply. Think about which colours would work best in your plot and play around with them. There's a whole range of plants that hold their grey or silvery foliage all winter, fitting the season perfectly. These include: silver bush (Convolvulus cneorum), a compact, spreading shrub with shiny leaves that look as if they've been spray painted; Artemisia 'Powis Castle', with its soft, ferny, pale-silver foliage; and Helictotrichon sempervirens, a grey, arching evergreen grass. They all look great together in a large pot for seasonal interest and can then be transplanted into the garden next spring to provide interest for years to come.
How Do I Know What Celestial Events Will Be Visible Soon?
Google will tell you most of these things, as they are all regular and 'calculatable' events. Wolfram Alpha has a very comprehensive eclipse set-up too. Or you can simply buy a book - there are plenty of 'star guides' that include dates for eclipses and meteor showers.Unless you have your camera hooked up to a telescope, or you have a massive lens and a motor drive, things like planetary alignments are probably not worth driving out of town for. Likewise, meteors are tricky to photograph as they are unpredictable and flash across the sky in a split second.Eclipses and comets are somewhat more stationary, but they are few and far between.Why limit yourself to 'events'? There's plenty in the night sky to photograph every night. The plain old moon can make spectacular photos, especially if you shoot it in its gibbous stage so you've got some shadows in the craters. Point your camera at the lower half of Orion's sword, open the shutter for 5 seconds, then take a look at the screen. You will see a glowing purple cloud: the Orion Nebula, a stellar nursery. Shooting things that are there every night also means you get good practice for taking photos of rarer astronomical eventsI want to get into astrophotography, and would like subjects that are a bit more unusual than the things we see every night like constellations and the moon.Where can I read about upcoming celestial events, such as comet appearances, lunar and solar eclipses, meteor showers, planet alignments, et cetera? What information can I use to predict which events will likely be spectacular, and worth driving away from city lights to photograph, and which events I can guiltlessly skip?
How About the Development for Led Outdoor Solar Street Light?
San Diego announced last year that it is building the world's largest smart city led outdoor solar street light IoT platform and using CityIQ solutions developed by General Electric (GE) to improve parking, traffic and public safety on city streets. The CityIQ solution is a smart city digital infrastructure launched by GE and based on Intel technology that provides sensors that can be installed in led outdoor solar street light.Austin Ashe, general manager of Current's Smart City, said that this is only the beginning, as most of the data collected by the led outdoor solar street light Internet of Things (IoT) network will be released publicly, and the city allows and encourages software developers to use the data to build applications to help Local residents and visitors. The led solar street light system network can also be connected to the city's existing ShotSpotter network, which automatically locates sources and monitors sound in real time, and many municipalities use ShotSpotter to increase the efficiency of law enforcement. The addition of smart led solar street light system can increase the coverage of ShotSpotter from 10 square kilometers (about 4 square miles) to a wider area.Led solar street light system can use the sensor network deployed throughout the city to alert the police to dangerous situations by recognizing the sound of broken glass or car accidents; through a gun detection application, they can pass precise positions in less than a minute. Information captures more than 90% of shooting incidents to help first aid personnel.San Diego is said to have the world's largest network of solar street light price list IoT sensors in the world, involving GE, AT&T and Qualcomm and other public and private sectors. The city is constantly striving to operate the city's intelligence, and recently won the 2018 Smart 50 Award.All of this started in San Diego and began to replace some solar street light price list with smart street lights·RELATED QUESTIONWhat is proffesional led stage lighting?When you're putting on an occasion, whether it is an unassuming school play or a party, stage lighting rental is an unquestionable requirement. Lighting is a main thrust of your production, giving brightening, center, detail and modifying the view of the group of audience. There is nothing that so vitally passes on an inclination superior to a decent lighting system, and with boundless inventive potential, will serve as an immense advantage for your creation.Focus, position and hanging:Conventional stage lighting must be set up because of these three contemplations. Focus refers to where the light will point; position alludes to where the light will start from; hanging refers to the real demonstration of hanging the light. Shading, force and example (assuming any) should be considered next.Types of stage lighting :Ellipsoidal - these lights are the conventional stage lights and thought to be the most critical. They are centering lights, the appearance in front of an audience of which can be adjusted by screens and channels.Fresnel - these lights are utilized for shading washes on the stage.Standard Jars - these lights are the sort you will see in even the dingiest of bars. Continuously a strong choice, standard jars can get hammered, are sturdy and simple to transport.Follow spots - these are spotlights used to pursue somebody around a phase.Obviously, there are increasingly choices accessible for stage lighting with the consistent progress of innovation. Presently you have the fundamentals; here are a couple of more alternatives:LEDs - these Professional LED Stage Lightingare useful for centered pillars and have been gradually supplanting conventional globules in stage lighting.Dizzies - these lights are round circles with a few Drove lights (more often than not of varying hues) covering the surface. The circle pivots in an assortment of bearings and examples, making a whirling, confounding example, consequently the name.Gels - this term alludes to the hues given to lights. They function as shading channels, and should work in congruity with the shade of the light itself to accomplish the craved impact.Once you have got your types of lighting down, you'll have to consider where to place them. Here's an essential summary of lighting positions:Front - This is utilized for the most part for perceivability and shading impacts. Side - can be utilized to awesome impact to complement activity.Back - Additionally utilized for impact. This kind of lighting can make the dream of profundity on a phase, or notwithstanding to silhouette a man totally.
Walking with Heroes at Kokoda
NESTS of long, slender bird-of-paradise plumes sway on bobbing heads above painted faces streaked in yellow, red and black.Kauri shell vests tinkle in the tide of sound and boars' tusk grins leer from decorated mouthpieces. It is a scene the ancient razorback ridges of the Owen Stanley Ranges of Papua New Guinea have witnessed countless times over the centuries as the sound of kundu drums thumps through the green cathedral of the surrounding jungle. Through dancers' movements, the vibrancy of life pays homage to the mystery of death. But this year it is more significant. Early next month, the people of the Owen Stanleys will gather at Kokoda to mark the 70th anniversary of the end of the Kokoda Campaign in World War II. In previous years it has been called Kokoda Day, but two years ago the PNG Government initiated National Fuzzy Wuzzy Day to commemorate not only the Australian soldiers who fought and died on the track in 1942 but also the native porters who helped them. On November 2, 1942, advance scouts from the Australian Army's Maroubra Force entered the Kokoda government station to discover the Japanese had retreated. By evening, Kokoda was occupied by the battalion. The next day, members of the Australian 25th Brigade stood in silence at a memorial service followed by a flag-raising ceremony in which General George Vasey marked the recapture of Kokoda after three months of bitter fighting. In Kokoda on November 2, Fuzzy Wuzzy Day celebrations will be a mass of feathers, face paint and possum fur cloaks as the locals gather for this special sing sing. The Koiari are proud of their forefathers, the Fuzzy Wuzzy Angels, who were among more than 50,000 tribesmen who worked as porters for the Diggers in Papua New Guinea during World War II. The "angels" helped stretcher out wounded Australian soldiers over countless kilometres of steep, muddy, slippery track. In the week leading up to November 2, Koiari families and clan groups walk the rugged Owen Stanleys, sometimes for days, to reach Kokoda for the ceremony. The Australian and Papua New Guinea flags are raised in a sombre memorial service followed by a re-enactment of Fuzzy Wuzzy Angels carrying the wounded in stretchers made with blankets and sapling poles cut from the jungle, lashed together with vines. The dancing is held on Kokoda's oval, perched on the edge of a small, grassy plateau, less than 50m from the now-collapsed trenches desperately dug by the Australian militiamen of the 39th Battalion in July 1942. The dancers are crowned in spectacular headdresses, their faces painted in a rainbow of colours, their oiled bodies decorated with tropical flowers and draped in necklaces and vests of kauri shells. As a living, breathing war memorial, the Kokoda Track is unique. Trekking and tourism annually generate about $1.8 million, shared among the villages along the track. About 4000 Australians trek the Kokoda Track each year, says Professor Jack Carlsen from Curtin University's Sustainable Tourism Centre. When the young, untried soldiers of the 39th Battalion confronted the seemingly invincible forces of the Imperial Japanese Army on the Kokoda Track in 1942, little did they know the legacy they would leave for future generations. Like no other war memorial in the world, it is no sombre granite edifice, no sea of marble headstones or white crosses the Kokoda Track is 96km of mud and gnarled tree roots, hugged by dense, green jungle, blanketed by humidity and soaked by tropical rain. But there is also great beauty. In a high mountain village, trekkers are treated to the spectacle of the rising sun illuminating the cloud base far below as it makes islands of the mountain peaks. Looking like nature's avatars, vivid blue and yellow butterflies flit through the dense green of the jungle. They appear so sharp against the backdrop that they look out of place, as if they have been computer generated. Since the establishment of the Kokoda Track Authority in 2002, more than 30,000 trekkers have walked the track, their ages ranging from 12 years to more than 80. I walked it with 62-year-old trek leader Jim Drapes, of Brisbane-based Back Track Adventures. As a trek leader, Jim has crossed the track 28 times in the past decade and is on the track again next month to commemorate Kokoda's 70th anniversary. "The fitter you are, the better you are able to take in the experience, both at a historical and an environmental level," he says. "The track passes through a beautiful, dramatic landscape as you walk the ranges." --- The spirit lives on The Kokoda Track Foundation (KTF) is an Australian philanthropic organisation which aims to repay the help given to Australian soldiers during World War II by the people of the Owen Stanley Ranges in Papua New Guinea. Established in 2003, the KTF's goal is to improve the lives of the descendants of the Fuzzy Wuzzy Angels. In the 70th anniversary year of the Kokoda Campaign, the KTF is expanding its programs in education, health, community development and micro-business training, working in 40 villages along the track. -- The work includes: Providing 3500 solar lights, one to every adult living along the track in 2012. Supporting more than 350 primary, secondary, and tertiary students on Fuzzy Wuzzy Angel Scholarships. Providing elementary, primary and secondary schools with educational resources and infrastructure support. Helping train 60 elementary school teachers and several primary teachers, in association with education authorities in PNG. With Rotary Australia, the foundation has delivered 80 classrooms' worth of furniture to 21 schools. Continuing the Archer Leadership Scholars Program, a scholarship awarded annually to six PNG tertiary students. Helping provide vital, village-based healthcare. In partnership with Rotary Australia, the KTF has provided 100 hospital beds to hospitals and health centres. -- For more information, visit kokodatrackfoundation.orOriginally published as
How to Design and Calculate Solar Street Light System?
Result of the calculation is the minimum number of PV panels. If more PV modules are installed, the system will perform better and battery life will be improved. If fewer PV modules are used, the system may not work at all during cloudy periods and battery life will be shortened.General question regarding installed modules and performanceAlso better saving pages just into ee and not as files will bring you huge improvements on the performance side !How do other modules update elements using AJAX callbacks?I think you must to create block_wrapper in the $form before ajax as a container :to make ajax wrapper found itWill WD40 kill my DDR RAM memory modules?Quite possibly.

This is highly recommended reading. It gives guidelines to help writing code that is both readable and consistent. The Python community tries to follow these guidelines, more or less strictly (a key aspect of PEP 8 is that it provides guidelines and not strict rules to follow blindly). It deals with various aspects of the code style: naming conventions, indentation convention, etc.You will find various tools to try to check whether your code is PEP 8 compliant and if is it not, to try and fix this:In your case, the major point is that indentation should be 4 space. Also, you should not have trailing whitespaces. ModulesSplitting the code into small modules can be a good idea. However, I find page_01 to be a pretty weird name. Also, the way the code is splitted in different modules does not seem to be perfect to me. The way you use storage suggests that is should probably be a data structure (a class?).For the time being, let's move everything back to a single file:Functionsplayer_update does not update the player, maybe print_player would be more relevant.Similarly, I would expect ask_player_for_move to be a function returning the move asked to the user. In both cases, it seems like the functions could be used in the "main" part instead of duplicating the code.Hidden recursionYour game loop relies on a hidden recursion: player_move calls ask_player_for_move which calls player_move. This makes things heard to follow but also will add another level of function calls in the stack. This can be an issue if you need a backtrace because you will get something like:but the other issue is that you could end up reaching the recursion limit.You could write something like:Then you could move the call of game() behind an if __name__ == "__main__": guardERROR: could not open directory /lib/modules/4.2.0-25-generic: No such file or directoryI just needed to set the kernel in Digitalocean.

Save Commercial Energy Using Integrated Solar Street Light
Now, integrated solar street light that is smarter and saving energy is increasingly loved by people. Why say everything on a street smarter and energy saving.We offer sunlight for street and area lighting based on the most reliable technology and the LED that delivers lighting for a very long time. These are having very high efficiency solar panels and batteries without maintenance.Available in centralized as well as decentralized, to acclimatize to the different requirements of the client and the site. Decentralized models provide the advantage of reducing any additional cost of electrical wiring to reach remote or distant locations that require lighting. Later these models come with the characteristic of automatic dusk at dawn thus allowing autonomous operation without requiring any human intervention on a daily basis. Centralized sunlight is more suited to places where existing lights and poles are installed. Solar powered integrated solar street light of independent pole type are available in wattage from 7W and going upwards until 120W.The sunlight of our product carries enough reserve to supply any weather situation such as rain and fog.Our integrated solar street light is being used in cities, municipalities, etc. to illuminate city roads, lanes, colonies, and roads that provide much needed lighting and visibility without relying on grid power. These solar lighting solutions are financially very rewarding since they not only come with a low initial investment, but they continue with the profitability in terms of energy savings accumulated over time.We are witnessing a greater environmental awareness, street lights with solar energy are a definite way to go green and be sustainable.These lights are backed by our standard warranty, which guarantees total peace of mind for the customer.In the past, integrated solar street light panels used large crystals made mainly of silicon that produced electricity when exposed to light. When electrons in silicon are exposed to light, they begin to vibrate from their fixed positions following the rules of thermodynamics. In addition, it produces heat from vibration and movement. Through this, silicon converts a large part of the energy of light into electricity. However, manufacturers found silicon too expensive to manufacture and to put as a component of solar lamps·RELATED QUESTIONWhat's the meaning of Sia's Chandelier song?Before Chandelier, Sia was a singer with mediocre success.She was really struggling to push her career when she lost her partner to an accident.

Led solar street light outdoor are really bringing sunshine to the night and illuminating your way home!Does indoor light make your skin darker?Nope. Only the sun rays can change your skin colorDo solar powered items work indoors?No - or only in a window where it's still in full sun. Direct sunlight has an energy level if over 1000 Watts per square metre; even fairly inefficient solar panels can extract a lot of energy from it. For indoor lighting to reach levels like that, a 12ft square room would need a light source of around 50,000 watts. Normal indoor lighting simply does not compare to Sunlight.Can Solar panels absorb the light from indoor lights like they do from the sun?Indoor Solar PanelIs it ok to expose a new role of film to indoor light as you load the camera?was the film already in the container?My aftermarket radio, car clock and indoor light doesnt work?What you choose is to look on the chassis length, on your case that's the two a DIN (2" tall) or DD - Double DIN - (4" tall) type receiver, sounds like your beginning is presently the DIN-type. there are various length codes, you will see I, J, IR, E U, and so on. so a ways as employing a DD receiver truly, you have room on your sprint for that, the Camry is listed as a DIN or DD receiver automobile, and it does no longer be listed if it was not a particularly uncomplicated deploy for DD besides. there is probable yet another 2" of wasted height on the sprint that may no longer used via the producing facility receiver that the DD could take upHow should I transition my Thanksgiving Cactus to artificial indoor light?This site gives the following temperature information when flowers are setting:Temperature: To set flower buds, the plant needs cool 60-65F/16-18C days and 45-55F/7-13C nights.

Questions About Common Led Solar Lights
Could you write a one paragraph bio/testimonial about yourself that sounds entirely fictitious/embellished but is actually completely true?Rei was born in a vast industrial wasteland where the sky glowed burnt orange at night and the odd explosion rocked the nearby houses. Rei is descended on one side from a mysterious orphaned farm boy, and on the other side from a fierce war veteran matriarch. Reis formative years involved being inducted into a mysterious local group listed in the phone directory as a satanic cult, where Rei learned to wage war and perform magic while hordes of people insisted on giving Rei expensive pieces of cardboard. Rei has spent time learning how to fly, climbing silk, building artificial intelligences determined to cover the world with carpet, swimming on the ocean floor, and occasionally hitting people with things, all while working full time and obtaining several academic degrees. Rei has trekked through the jungle, performed at the opening ceremony for the Olympics, and hugged eight incarnations of The Doctor. Over the years, Rei has ushered many people through doorways to other worlds, where they have learned to fly in Never Never Land, run a starship, saved the world from giant rocks, time travelled, and attended Hogwarts.------Should Italy quit the Euro & Eurozone?

Is there evidence of that?Michael Heseltine, being a typical Britain and spending all his time in pubs, shopping centres, Jobcentres and canteens, will obviously be a reliable source for the views of the common man, particularly those in the North?Michael Heseltine - WikipediaMichael Ray Dibdin Heseltine, Baron Heseltine, CH, PC (born 21 March 1933) is a British Conservative politician and businessman. After initially making money as a property developer, he was one of the founders of the publishing house Haymarket. He was a Member of Parliament from 1966 to 2001, and was a prominent figure in the governments of Margaret Thatcher and John Major including serving as Deputy Prime Minister under the latter.Heseltines ownership of Haymarket has made him a large personal fortune. As of 2013 he was ranked 311th in The Sunday Times Rich List with an estimated wealth, including shareholdings held by members of his immediate family, of 264 million.I think it would be possible to find sources who more accurately reflect the opinion of the average person.------After 10 years, who will be remembered the most - Sachin Tendulkar, MS Dhoni or Virat Kohli?Do you remember the 112 in the 1992 Perth Test?Do you remember the 65 in the 1996 World Cup Semifinal?Do you remember the Desert storm innings in 1998?Do you remember the 140* against Kenya in 1999 ICC World Cup?Do you remember the 673 Runs in 2003 ICC World Cup?Do you remember the 98 against Pakistan in 2003 ICC World Cup?Do you remember the 241* in Sydney 2004 Test?Do you remember the countless nervous 90s in 2007?Do you remember the 200* against South Africa in 2010?Do you remember the 148 against Pakistan in 2005?Do you remember the 183* against Sri Lanka in 2005?Do you remember the 91* in 2011 ICC World Cup final?Do you remember the 183 against Pakistan in 2012?Do you remember the 82* against Australia in ICC World T20 2016?Do you remember the 100* against Australia in 2013?Do you remember the 112 against Pakistan in 2013?Scan your brains and hearts but lets just tell which of these memories are etched forever in your life!You got your answer guys, it will always be Sachin Tendulkar, today, after 10 years and even after 100 years!!------What are your thoughts on Fox News host Chris Wallace fact checking Donald Trump and telling him that he's wrong to claim that Biden wants to defund the police?My thoughts,That while Trump was wrong in the wording Biden used and extent to which he wants to defund police, that Wallace was also absolutely wrong.You see, two things can be true at the same time.If Wallace wants to fact check something, he damn well should be correct about it, and he wasnt. (Same goes for Trump claiming something)Biden said that he wants to shift funding from police to other programs like mental health.When you take funds from a programs budget, that is defunding. Plain and simple.Additionally, any time that it is suggested that a programs funding be frozen at current levels, or even not increased as much as expected over the previous budget, those in D.C. always cry to the media about important programs being defunded. That means that by use of the term that Biden has used in the past, and surrounded himself with for forty years that he was talking about defunding the police.But, yes, Wallace was correct that Biden did not say abolish the police, nor did he say to completely defund them.------When i connected 4 LEDs i read 0.5 volt on my voltmeter.I added 4 more LEDs and it reads 1 volt,why is that?Assuming they aren't connected to a power supply, probably the ambient room light is charging them up and your voltmeter is loading them down a little bit, too. LEDs work as light sensors as well as light emitters.If you are trying to use your LEDs as light sensors, that's one thing. (A lot of methods are available there.) If you are trying to use them as a power source, that's going to be a lot more complicated (and mostly impractical except in rare circumstances where you actually know what you are doing and why.)Regardless of any of that, you can't expect to increase both voltage and current without an external power supply. Useful power out is always less than useful power in. You can "optimize" the load point to improve the net power extracted from a solar cell (or, for gosh sake, an LED.) But that's circuit design, not a violation of physical laws.------How much have you grown as a person from the time of your first Quora answer to your most recent?I think I have grown as a person. I like Quora because it gives me a chance to think and write on subjects that are important to me, learn and possibly, on rare occasion help someone.I get a lot of satisfaction from writing on Quora and so far I havent been trolled which I have an aversion to. I think a lot of questions have answers that are easily found elsewhere but not the qualitative kind.I would turn off my stats if I could but I dont really want to be anonymous. My picture and name are not my own and thats enough. I am not really interested in the numbers game, just the questions and answers. I dont care about being upvoted or not. It is nice to be published and have a database that has all of my musings. It is a modern form of self-reflection or contemporary intellectual snapshot.As far as things to do on the internet there is a lot worse out there.------What is the worst personnel ratio in which wars have been won?The battle of Auerstedt in 1806. (1:2 ratio)A single corps of the French Army defeated the entire Prussian army. The French were measly 27,000 and the Prussians were 62,000, more than double the number of French.The battle started when they collided with single divisions in morning. Both the sides started getting reinforcements piece-meal. However, the Commander of the French III corps was none other than Louis Nicholas Davout, whose superb training and stern discipline created the best fighting force of the Grand army. The Prussian Army had somewhat rotted. From the days of Fredrick the Great, the Prussians had lost their discipline.In the end, the entire Prussian line was broken, their commanders were mortally wounded and the French were counter attacking.In an age where line formations formed and even small number of troops could be used for flanking formations, this battle can be considered epic.Another battle that comes to my mind is the Battle of Saragarhi Ratio (21 Sikhs vs. 10,000 Afghans). The sikhs fought to the last man and killed or wounded approximately 180450 Afghans. So yes its a strategic victory.Hope this helps !------Why has Norway not joined the EU?HiNorway let its citizens decide and they voted against. Instead of that, Norway joined the EEA, and is therefore part of the European Market (including the right to enjoy and the plight to grant the Four Freedoms to other European citizens).To be a member of EEA, Norwayhad to accept the basic constitution of the single markethad to accept the jurisdiction of European Courtshas to accept new laws and regulation from the EU, to a certain degreepays substantial amounts to the European Union, without having a say in its politics and decisionsSo You might argue that itd be more clever for Norway to be an EU member. However, it would also mean giving away more juridical power, and accepting external policies (e.g. on fishing, which is much more regulated by Norway then by other EU members). At least, being a member of the single market is as valuable to Norway that theyre willing to accept all this to gain acces.------Why is Russia apparently such a big threat to the US?Russia and the United States do not share the same agendas and have contradicting interests in regards to peace and stability. Russia isnt necessarily a threat to US national security but more of a threat to their national interests and agendas (though national security and interest do coincide).Path to U.S.-Russia CooperationAmerican Interests, Russian InterestsRecently, the Middle East has become a hot debate with the two nations conflicting agendas.U.S.-Russia Competition in the Middle East Is BackUS and Russia Interests in Middle EastThe two nations contradicting interests heated up in UkraineThe True Interests of the US and Russia in UkraineThe Obama Doctrine and UkraineBut most of all, Syria has been the center of the two nations heated agenda rivalry, some calling it a proxy conflict between the twoSyria crisis: Where key countries stand - BBC NewsThe Syria Strike: Are the United States and Russia On a Collision Course?Russia versus the United States in SyriaRussias interests - What Russia Wants in SyriaUnited States interests - Americas Vital Interests in Syria------Some scientists often consent to this statement: "For every creation, there should be a creator." Would you deny this?Im not sure if it was intentional, but your question commits the fallacy of begging the question. An argument begs the question when it assumes what it claims to prove. The Mona Lisa is a creation. Does the Mona Lisa have a creator? Well, of course it does. It couldnt be a creation if it didnt!Its a pedestrian truism that all creations have creators. The meaningful question is whether the natural worldor at least certain aspects of itare creations. If it can be shown that they are, then the theist has established something significant. Of course, he still hasnt proven theism. Even if the natural world has a creator, it doesnt follow that the creator is omnipotent, omniscient, morally perfect, eternal and possessed of the other properties ascribed to the theistic god. Still, it would be a nice start. But many people have proposed arguments for this conclusion and so far none has survived rational analysis.

To any observer on the ground looking at the sky with the naked eye, the sky appears to be a vast spherical bowl, a celestial sphere that extends from all points along the horizon to the zenith, the point directly overhead. Astronomical objects seen in the sky are so far away that observers viewing them without the aid of a telescope have no intuitive sense of which objects are closer than others. This lack of depth perception causes everything to appear equidistant on the sky. Any object's position on this sphere can be determined by two coordinates, which designate the object's horizontal and vertical location. The vertical coordinate is determined by measuring an altitude angle upwards from the nearest point on the horizon, and the horizontal coordinate is established by measuring an azimuth angle from due north eastwards along the horizon to that nearest point. This system is called either the horizon coordinate system or the altazimuth system (see Figure 1). About 6,000 stars are visible to the naked eye when you can achieve the darkest conditions. The positions of the stars relative to each other remain fixed from night to night and year to year. In general, stars in the same area of the sky have no physical relationship to each other, but the very human tendency to impose order upon otherwise random distributions yields patterns of brighter stars, or constellations. Many constellations of the Northern Hemisphere have been inherited from antiquity, including Ursa Major, the Big Bear, of which the more familiar Big Dipper is part, and Orion, the hunter, which can be seen in the winter sky. Many Southern Hemisphere constellations were defined in the last century to fill in unlabeled regions of the sky. The sky is now officially divided into 88 constellations, which are used in modern astronomy for naming purposes. For example, the star alpha Ursa Majoris ( UMa) is located in the Big Bear constellation. Therefore, Ursa Majoris comes from the name of the constellation, Ursa Major, and the Greek letter indicates that it's the brightest star within that constellation. In addition to modern names, some 90 or so stars also have names from antiquity. For instance, UMa is also known as Dubhe. Over the course of the night, stars move across the sky from east to west as a consequence of Earth's rotation on its axis. The stars appear to move in circular paths around a celestial pole, or either of two points on the celestial sphere where the extensions of Earth's axis would intersect. In the Northern Hemisphere, the celestial pole is coincidentally marked by the relatively bright star alpha Ursa Minoris, also known as Polaris. Simple geometry shows that the altitude angle of the pole star above the northern horizon is equivalent to the latitude of the observer on Earth. To an observer in the Northern Hemisphere, stars that are always above the northern horizon are known as circumpolar stars; an observer in the Southern Hemisphere would see circumpolar stars around the south celestial pole. Stars that are further to the south and that rise and set sometime during the night are called equatorial stars. Equatorial stars rise in the east, move diagonally into the southern sky, achieving their highest position above the horizon on the meridian (the great circle that extends from due north on the horizon, through the zenith, to due south on the horizon). From the meridian, these stars move westward until they set below the western horizon. The celestial equator is that great circle formed on the celestial sphere by extending the plane of the Earth's equator. The equator intersects the horizon due west and due east. An immediate consequence of Earth's rotation is identifying the preferred directions of north, south, east, and west around the horizon, called cardinal directions, by which humans naturally orient themselves. Minute by minute, over the course of the night, both the altitude and azimuth of a star continually change. To more easily observe and track celestial objects, scientists have defined celestial coordinate systems that are fixed upon the sky and thus move with the stars. The equatorial coordinate system is a projection onto the sky of Earth's latitude and longitude coordinate system. Celestial latitude, known as declination, is the angular position north or south of celestial equation. Celestial longitude, measured around the celestial equation, is known as the right ascension (see Figure 2). Declination is measured in degrees, minutes of arc, and seconds of arc. Recognizing that the stars appear to move once around the sky in one day (24 hours), right ascension is measured not in degrees, but in hours, with 24 hours of right ascension (to distinguish from 24 hours of time) equal to 360 degrees. Like the stars, the Sun rises and sets every day. However, unlike the fixed motion of the stars, the Sun's daily path across the sky varies throughout the year. Twice annually, at the vernal equinox (about March 21) and the autumnal equinox (about September 21), the Sun's position coincides with the celestial equator; it rises due east, moves across the sky following the path of the equator, and sets due west (see Figure 3). At this time of year, the length of the day is the same as the length of the night. During the summer, however, the solar position is north of the equator, achieving a maximum northernmost declination of 23.5 degrees at the time of the summer solstice, around June 21. In the winter, the solar position is reversed, with the Sun at its maximum southernmost declination of -23.5 degrees at the time of winter solstice, December 21. The terms equinox and solstice mark not only specific times of the year, but also specific points in the sky. The vernal equinox is that position on the celestial equator where the Sun crosses from the southern into the northern sky. Celestial longitude (right ascension) is measured eastward around the equator from this point. The Sun's seasonal positions in the sky. Relative to the background stars, the Sun also moves about one degree eastward each day, thus encircling the sky in the course of a year. This ecliptic, or the great circle on the celestial sphere defined by the solar path, is tilted with respect to the celestial equator by 23.5 degrees. Throughout the year, the ecliptic passes through the 12 zodiacal constellations. Because the apparent solar movement is caused by Earth's motion around the Sun, the ecliptic plane is also a projection of Earth's orbit about the Sun. That Earth's rotational equatorial plane does not perfectly match its orbital plane (the ecliptic plane) about the Sun is directly responsible for the annual northsouth movement of the Sun and the consequent seasons. The length of the year is based on the time that the Sun takes to complete its annual path around the sky. During the year, the stars and constellations visible at night change as the seasons pass through their cycle. A year is, in fact, 365.25 days long. To keep the calendar in sync with the actual seasonal passage of time, every four years we have a leap year, or a year of 366 days. The additional day, February 29, makes up for the time lost annually when the 365.25 day cycle is computed as 365 days. The length of a day is based on the time it takes for the Sun to complete its daily path across the sky, from its crossing of the meridian at noon to its next crossing of the meridian the next day. Daily time based on the hourly position of the Sun in the sky, relative to its noontime position each day, is called apparent solar time. To astronomers studying the stars, however, the time of day alone is not a sufficient method for determining which stars can be observed at any given time. Astronomers need to know both the time of day and where the Sun is in the sky to find out which stars they can observe. More specifically, what is of interest to an astronomer is the sidereal time, or the right ascension of the stars that are crossing the meridian at any moment. Sidereal time and solar time are not equal because of the annual motion of the Sun across the sky. The true rotation period of Earth is 23 hours, 56 minutes, but the length of the day is four minutes longer. In one rotation of Earth, the Sun has moved roughly one degree across the sky, thus Earth has to rotate a little bit longer to get the Sun back to the same position on the sky. The solar day is 24 hours long. The actual length of any given day varies throughout the course of the year for two reasons. First, Earth's orbit around the Sun is not a circle, but an ellipse. The Sun's apparent motion across the sky therefore varies slightly, moving more than the average one degree per day in January, but a bit less than the average in July. Second, the solar motion along the ecliptic moves parallel to the celestial equator at the times of the solstices when the Sun is farthest north or south of the equator, but at the times of equinoxes, its motion is at an angle to the celestial equator. What is important for the length of the day is only that part of the solar motion parallel to the equator. This produces a second variation to the length of the day. The difference between apparent solar time (which would be shown by a sundial) and mean solar time (which would be shown by a clock or watch) is called the equation of time. This is a complicated effect involving orbital mechanics (the motion around an ellipse is not uniform), perspective (a moving object closer to the observer has a greater apparent motion), the tilt of the ecliptic to the equator (hence the daily component of solar motion across the sky varies from equinox to solstice), and a geometrical factor resulting from the fact that we are dealing with a spherical coordinate system; this latter you can demonstrate to yourself by placing your thumb on the equator of a globe. Note how much longitude angle it covers. Now place your thumb near the north pole. Your thumb will cover the same area, but as measured in longitude, it covers a much bigger longitudinal angle. And it's that angle that is important for rotation and hence the length of a day. Noon, as defined by mean solar time, can occur as much as 16 minutes late in October or 14 minutes early in February compared to the Sun's actual crossing of the meridian. Observation of the Moon shows that it not only appears to change its position by moving around Earth, but at the same time, the fraction of its surface that is illuminated by sunlight (its phase) also changes (see Figure 4). When the Moon is directly opposite the position of the Sun, it appears totally illuminated, or in full phase. When the Moon is viewed at an angle of 90 degrees from the position of the Sun, its surface appears half illuminated, or in its quarter phase. Between full and quarter Moon, the phase is said to be gibbous. If less than half the Moon is illuminated by sunlight, the phase is crescent. When the Moon is in the direction of the Sun and the side toward Earth is its dark or shadowed half, the Moon is said to be new. The cycle from new Moon waxing (increasing illumination) to first quarter to full Moon, then waning (decreasing illumination) to third quarter and back to new Moon takes 29.5 days, a period adopted as the basis of our calendrical month. The lunar phases are observed because of the changing geometrical orientation between the Sun, Moon, and Earth over the course of the lunar month, not the result of Earth casting its shadow on the Moon. The Moon takes 27.3 days to move once (360 degrees) around Earth as determined by its orbital position relative to the stars; the orbital period is therefore also an example of a sidereal period, a period measured relative to the stars. This 27.3 days can also be called a sidereal month. The time from full Moon to full Moon is longer, 29.5 days, because two motions are involved: the motion of the Moon around Earth and the motion of Earth around the Sun. To become full again, the Moon must move more than 360 degrees around Earth. The lunar month, or lunation, is thus an example of a synodic period, or a period produced as the consequence of two motions. The term synodic month is also applied to this 29.5 day period. Another example of the difference between a sidereal period and a synodic period is the rotation of Earth (23 hours, 56 minutes) and the length of a day (24 hours). The actual path across the sky of the Moon is quite complicated. The lunar orbital plane is tilted about 5 degrees 9 minutes with respect to ecliptic plane. The orientation of these two planes rotate with respect to each other over an 18.6 year period. In consequence, relative to the celestial equator, the lunar orbital plane has a variable tilt that periodically oscillates from 23.5 degrees minus 5 degrees 9 minutes equals 18.3 degrees, to 23.5 degrees plus 5 degrees 9 minutes equals 28.7 degrees. In other words, over the course of the month, the Moon can oscillate north and south across the celestial equator between declinations of as little as 18.3 degrees to as much as 28.7 degrees. Each month the path of the Moon across the sky differs slightly from its path the prior month and from its path the next month. In contrast, each year the solar path around the sky is essentially the same. Astronomers find particularly interesting the two intersection points, or nodes, between the great circles of the ecliptic plane and the lunar orbit. If the Sun and Moon in their motions about Earth move simultaneously through nodal positions, an eclipse occurs (see Figure ). If the Moon and Sun are at the same node, the Moon passes in front of the Sun and a solar eclipse results, lasting only a few minutes in duration. If the two are at opposite nodes, then the Moon passes through the shadow of the Earth and a longer duration lunar eclipse occurs. The cycle of occurrence of eclipses is quite complicated because three factors are involved. The Sun moves around the sky in 365.25 days. The Moon moves once around the sky every 27.3 days. The direction to a node (where the two orbital planes intersect) moves around the sky in 18.6 years. To get an eclipse, all three positions (Moon, Sun, and node) have to be along a straight line through Earth. This event does not happen with a simple pattern of regular time intervals. Nakedeye observers in antiquity recognized five other objects that move across the sky relative to the stars - the planets. The word planet comes from the Greek, meaning "wanderer." Planetary motion is more complicated than that of the Moon or Sun, which move systematically west to east relative to the stars. The planets' usual motion is west to east, termed direct or prograde motion. But in each synodic period, planets show a brief period of motion in the opposite or retrograde direction. Retrograde motion is the result of perspective. Consider, for example, driving on a freeway. You look forward toward a slower moving car. Relative to the distant mountains, it is clear that this car is moving in the same direction you are moving. But as you catch up to and bypass the slower car, you see it appear to be moving backwards compared to the distant horizon. As you pull ahead, once again looking back at the slower car shows it to be moving forward. Observation of other planets from Earth produces the same apparent reversal of motion relative to the background of stars. (See Figure 6).
