Question by Beefcake: What solar panel type to power a conventional typical light bulb?
I built a shed out back and I would like to install a solar panel to power a small light inside and outside of the shed. Or maybe just the inside. Does anyone have any advice and suggestions?
I’m confused now
Well, i plan on just using it when i go out to the shed and need a little light on to see inside at night.

Wow, so many great answers!

My suggestion is to buy a solar powered shed light.

I suppose you could make one… figure out the maximum amount of time you could possibly need the light during a day, convert to hours… multiply that by the wattage of the light source you intend on using… that gives you a watt/hour rating for a battery storage device. Find yourself a solar panel with a voltage that’s usable for the circuit you are making, 12v usually or maybe 5v for led lights (but then there’s some circuitry that needs to happen to make that one work). You figure out the amount of sun you’ll get there on a short day (think winter solstice) in hours and then figure out how many watts your solar cell needs to put out to charge that battery from earlier.

Say you have a 18 watt/hour battery (12v) and a 2 watt solar cell (12v) and you get 9 hours on the solstice… see? 2×9=18
Now you need to put in an overcharge preventer, so you don’t overcharge the cell on longer days, or days you don’t use the light… and voila!

Or you can buy a solar powered shed light….

Mathematics and computer science are not natural sciences, applied sciences (technology) or social sciences.
So, what kind of sciences are they?

I found out that they may belong to constructive sciences or formal science but I am not sure.

PLEASE DO NOT ANSWER WITH LINKS.

Thanks.

Answer by research_student09
Mathematics, which is sometimes classified within a third group of science called formal science, has both similarities and differences with the natural and social sciences.[2] It is similar to empirical sciences in that it involves an objective, careful and systematic study of an area of knowledge; it is different because of its method of verifying its knowledge, using a priori rather than empirical methods.[4] Formal science, which also includes statistics and logic, is vital to the empirical sciences. Major advances in formal science have often led to major advances in the physical and biological sciences. The formal sciences are essential in the formation of hypotheses, theories, and laws,[5] both in discovering and describing how things work (natural sciences) and how people think and act (social sciences).

Cognitive science is a rapidly evolving field that deals with complex cognitive processes, intelligent systems, and the emergent behavior of large-scale real-world computational systems. It is an interdisciplinary study. It draws from converging evidence and methodology of diverse fields, including psychology, physics, neuroscience, philosophy, information science, COMPUTER SCIENCE, anthropology and linguistics. The term cognitive science was coined by Christopher Longuet-Higgins in his 1973 commentary on the Lighthill report, which concerned the then-current state of Artificial Intelligence research. In the same decade, the journal Cognitive Science and the Cognitive Science Society began.

Science Teacher Resources: Things Many Science Teachers Can?t Live Without

Science teachers have resources that they use all the time for teaching their students and also for educating themselves on certain scientific subjects. A science teacher will often be required to know far more about the subject matter that they are teaching than the students who are being taught. This makes them more effective, by having a complete understanding of their subjects. This also allows them to answer almost any questions that their students may have. These teacher resources are often in the form of books, peers, or websites. There are also scientific products and supplies that they can buy, which come complete with a lesson guide.

These types of teacher resources end up being incredibly useful. In the end it means that the teacher can spend more time on other things, rather than trying to come up with a lesson on their own. These types of ready made science lessons are a wonderful resource for teachers, particularly those teaching physical science or physics. The best part of these science products is that they come with full instructions, not only on how to make the demonstration work, but also include a detailed explanation on how and why it works as well. This type of hand-on science learning provides a great tool for teachers of all grade levels, starting from a very young age. It has been well demonstrated that when learning becomes more interactive, retention levels increase exponentially.

The instructions and explanations that come with these scientific products and supplies simply mean that the teacher won’t have to spend precious time researching the subject for explanations on why each part of the experiment works. Teachers are also free to utilize these demonstrations as they see fit, using as much or as little of that information as they would like to. For example, when dealing with higher grade levels, they can be very detailed and study the phenomena with great detail. Alternately, when teaching younger children, a more simple explanation will do fine.

These types of teacher resources also come in a huge range of complexity and price. You can find experiments and demonstrations that use advanced physics like a Planck’s Constant measuring device, which demonstrates that energy isn’t a matter of intensity, but rather frequency. You can also find much more simple devices like magnets, color wheels and tape measures. No matter what grade or age the children are you are working with, you can find a suitable science product. The visual and hands on science experience often remains with people for years after their education is complete. In fact, if you ask most people about the things they remember from science class, often times it is only the hands-on experiments that they can clearly recall.

Each science classroom will have different needs, depending on the age level of the students and their individual abilities. In using these science products to teach physical science and physics, teachers can adjust the lessons, adapting them as they see fit for their students. A good science teacher will always have a variety of resources available to them, including hands-on science teaching products and supplies. Students will develop a better understanding of physical science and physics through the use of these hands-on science products.
