What’s In A Candle Flame?

What is a candle flame really made of? I am at the Palace of Discovery in Paris to do an experiment that beautifully demonstrates the answers. Ok so we’re turning on an electric field here and we see that the flame is spreading out. Thats very cute, it’s like a butterfly. And you can see […]

Carbon Nanotubes Might Be the Secret Boost Solar Energy Has Been Looking For

Solar panels are an incredible innovation in energy tech, but they’re way less efficient than they could be, because they have a problem: heat. Specifically, waste heat, or energy that’s lost while converting the sun’s energy into electricity. But a new technology—made possible by carbon nanotubes—may be just the thing that brings solar panels into […]

Energy & Electricity in Science : How Does Solar Energy Work?

Hi, I’m Steve Jones, and I’m going to explain how solar energy works. Now, solar means sun, so we know that the energy is coming from the sun, and we might think it comes as heat or whatever. In fact, we get all kinds of energy from the sun, but it is all radiation. Remember, […]

Energy & Electricity in Science : How Does an Electric Circuit Work?

Hi I’m Steve Jones and I’m going to explain how an electric circuit works. Well first of all we have to remember that there are certain things which conduct electricity which we call conductors and there are others which don’t conduct which are called insulators. Now conductors and insulators you must know the difference between […]

Electric Current: Crash Course Physics #28

Imagine you’re floating down a river. Maybe the stream is calm and serene, flowing without obstruction. Or perhaps it’s a rushing river, churning and splashing over rocks! Well, the way water moves in a river is a lot like how electricity flows through a wire. But when we say that electricity is flowing, we’re really […]

Fusion Power Explained – Future or Failure

The fundamental currency of our universe is energy. It lights our homes, grows our food, powers our computers. We can get it lots of ways: Burning fossil fuels, splitting atoms, or sunlight striking photovoltaics. But there’s a downside to everything Fossil fuels are extremely toxic, Nuclear waste is… well, nuclear waste, And, there are not […]

Newton’s Prism Experiment

(mechanical sound effects) – [Voiceover] In this video, we’re going to look at the relationship between white light and color by recreating a portion of Newton’s prism experiment, as presented in a letter to the Royal Society in 1671. But first, a little bit of background. At the time of his experiment, the prevailing theory […]

Turning Gravity Into Light – Smarter Every Day 146

Hey it’s me Destin. Welcome back to Smarter Every Day. If you’ve ever watched Smarter Every Day you know that I spend a lot of time off the grid. Right now I’m in the Amazon rainforest and I don’t really know what this thing is. I think it’s some kind of termite.. thing, on a […]

Cordless Anti-static Bracelet, Garbage or Junk?

Hi, Melvin asked me on Twitter if it is possible to make a bracelet that removes the static electricity from body and avoids shock Of course, there are these straps that ground the body and remove static electricity But is it possible to make a cordless one? And surely after I did a quick search, […]
