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

Hi I’m Steve Jones and I’m going to explain how nuclear energy works. Now nuclear energy generally is produced from either uranium or plutonium. Plutonium is another radioactive material. But the process is basically the same. And the process is called fission. Fission is something that happens in biological spheres that is a cell divided […]

Voltage, Current, Electricity, Magnetism

Particles can have a positive charge Or a negative charge Particles with the same charge repel one another Particles with opposite charges attract one another This is because charged particles create electric fields And Electric fields exert a force on charged particles When there is an electric field between two points … … we say […]

The Pain of Electricity (AC versus DC)

Hi. One of the common questions is that: what kind of electricity hurts more? AC (alternating current) or DC (direct current)? So, I’m going to measure the electricity pain level on a human’s body, which is myself. But first, let’s measure the resistance of the skin on tongue and fingers for reference. So first, let’s […]

Live Science: Static Electricity

My name is Dave and welcome to the Science Museum of Virginia. Electricity is the energy created by moving negative charges or negative ions. Over here I have a Van de Graaff generator, so let’s see what happens when negative gets near a positive. Ah what do you see? We’re experiencing a discharge of static […]

1. Class 12th Physics | Current Electricity | Electric Current | by Ashish Arora

dear students lets start with the topic of electric current. and, in your early classes you might have studied about the basic definition of current in which, we write that. rate of flow of charge. through. any cross section. of a conductor. in which current is flowing obviously we are talking about. is called. electric […]

Slower Than a Turtle – The Speed of Electricity

Hello I’m Daven Hiskey and you are watching the Today I Found Out Youtube channel. In the video today we’re looking at the surprisingly slow speed of electricity. Let’s get started. You may be surprised to learn that electrons flow through a typical copper wire much slower than a turtle walks. Each wire that conducts […]

What is STATIC ELECTRICITY? w/ Illustration

Everyone’s had that moment where they walk across their carpet and reach for a door handle, only to be greeted by an irritating shock. This phenomenon is known as static electricity, and a more drastic example can be seen when lightning occurs. Although chemists and physicists are unsure of how exactly static electricity works, many […]

Space is dead: A challenge to the standard model of quantum mechanics | Lee Smolin

So let’s first define what we mean by being a realist. What I mean when I say I’m a realist is that I believe that there is an exactly understandable way the world is, which is independent of our intervention, independent of our existence, our knowledge. It’s possible for everything that happens in nature, to […]

Schlieren Imaging in Color!

A few months ago, I made a video about Schlieren imaging. Now that’s a technique used to visualise tiny differences in air either temperature, pressure, composition, so you can see things like the heat that comes off when you light a match. Now in that video I asked you for some ideas for what you’d […]
