Have We Reached the End of Physics? | Harry Cliff | TED Talks

Why is there something rather than nothing? Why does so much interesting stuff exist in the universe? Particle physicist Harry Cliff works on the Large Hadron Collider at CERN, and he has some potentially bad news for people who seek answers to these questions. Despite the best efforts of scientists (and the help of the biggest machine on the planet), we may never be able to explain all the weird features of nature. Is this the end of physics? Learn more in this fascinating talk about the latest research into the secret structure of the universe.

The Meaning of E=mc^2

You’ve probably seen E=mc2 somewhere, in science class or maybe in cartoons or other pop culture ephemera, but if you really want to know what it means, listen to World Science Festival co-founder and Columbia University physicist Brian Greene’s explanation above. Then, once you have the basics of the relationship between mass and energy, go check out the Mass-Energy Scale from Minute Labs. Would you be surprised to know that the amount of energy used by the Large Hadron Collider in one year is roughly equivalent to the mass of an ounce of feathers?
