Physical Science : Going Green With Renewable Energy

Hi, I’m Steve Jones, and I’m going to tell you how to go green with renewable energy. Now, we know that at the moment we use these fossil fuels; oil, gas, coal, and nuclear fuel. We use them all to generate electricity for our houses, we use oil in our cars, petrol comes from oil. […]

2011 Nobel Prize: Dark Energy feat. Sean Carroll

You have known for a long time that the universe is expanding. If you look at distant galaxies, they are moving away from us, And the more distant galaxies are moving faster. So really, it’s not really an explosion of galaxies away from us; All galaxies are moving away from all the other galaxies. Space […]

Why Einstein Thought Nuclear Weapons Impossible

Now that we have nuclear weapons and nuclear power plants you might think that it was always Inevitable that we would be able to harness the energy inside the nucleus of atoms But that was far from the case in fact serious scientists, thought the idea was laughable like Nobel laureate Robert Millikan who in […]

Ep. 40 A Distant Asteroid, a Renewable Energy Record and a Marine Reserve | Twig Science Reporter

On this week’s news update– astronomers discover a visitor from another solar system, the small country with a big renewable energy record, and a huge marine reserve is created in the Pacific Ocean. First up, astronomers have been getting very excited about a recent visitor to our solar system! This is an illustration of an […]

Where Does Energy Come From? | Martin Archer | Ask Head Squeeze

Inspired by a question from CuttlefishPi on our Head Squeezers Google+ community, I thought I’d take you through one of my favourite bits of Physics where energy comes from. Now in my mind I think there are three different interpretations to this question and therefore three different answers: 1. Where did the idea of energy […]

Are Dark Matter And Dark Energy The Same?

Astronomers are the worst at naming things. I mean seriously. Dark energy AND dark matter? Who can remember which is which. But perhaps one astronomer has just fixed it, with a theory that says perhaps actually they are they same stuff. Dr. Jamie Farnes, astrophysicist at Oxford just published a paper suggesting that both dark […]

When Will We Be a Type III Civilization? Controlling All The Energy of the Milky Way

Now, I’m no futurist, but I think I can predict one thing. Humans love to use energy, and in the future, we’re going to use even more of the stuff. Let’s hope it’s clean energy, like that handy source of photons in the sky: the Sun. Not dirty forms of energy, like screams, unobtainium, liquid […]

What the HECK is Energy?

This episode was made possible by generous supporters on Patreon Hey Crazies. In my last video, I explained how mass and energy were the same thing and that got a bunch of you wondering: What the heck is energy? I’ve said a lot about energy on this channel, but it’s spread over multiple videos. It’s […]
