What Things Should Every Physics Major Know?

Over the weekend, cosmologist and author Sean Carroll tweeted about what physics majors should know, namely that “the Standard Model is an SU(3)xSU(2)xU(1) gauge theory, and know informally what that means.” My immediate reaction to this was pretty much in line with Brian Skinner’s, namely that …

We can't directly see black holes. But this time lapse shows the awesome power of their gravity.

Watch: stars orbit the supermassive black hole in the center of our galaxy.<p>No astronomer has even seen a black hole through a telescope. They’re dark, often occluded by matter, and actually very small compared with many of the stars in the sky. We’ve never directly seen the ring of material around …

Scientists have evolved a remarkable new form of life that can bond silicon to carbon

You're probably already familiar with a few products products that use carbon-silicon, or organosilicon: glues, caulks, and pesticides, to name a few.<p>But the new biological trick, which was forcefully evolved in bacteria, is safer and 15 times more efficient than synthetic, industrial chemistry at …

10 Quantum Truths About Our Universe

From the moment that it was discovered that the macroscopic, classical rules that governed electricity, magnetism and light didn’t necessarily apply to the smallest, subatomic scales, a whole new view of the Universe became accessible to humanity. This quantum picture is much larger and …

New Mathematical Model Maps The Expansion of The Early Universe Better Than Ever Before

This is where we came from.<p>Physicists in Switzerland are using new code called 'gevolution' together with Einstein's theory of general relativity to …

Our Universe: It's the 'Simplest' Thing We Know

Our universe is actually really simple, it's just our cosmological theories that are getting needlessly complex, argues one of the world's leading …

Scientists find DNA differences between gay men and their straight twin brothers

For men, new research suggests that clues to sexual orientation may lie not just in the genes, but in the spaces between the DNA, where molecular marks instruct genes when to turn on and off and how strongly to express themselves.<p>On Thursday, UCLA molecular biologist Tuck C. Ngun reported that in …

Get That Life: How I Became an Astrophysicist

Sara Seager is searching for life on other planets — and she's confident she'll find it.<p><i>Growing up in Toronto, Sara Seager was a curious child but never much cared for math or science — until she had to. During her junior year in high school, Seager realized she'd better start paying attention in</i> …

Einstein's Theory of General Relativity

In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum …

The Large Hadron Collider Is Back In Action

Yesterday, scientists at the Large Hadron Collider successfully turned it on, injecting two proton beams moving in opposite directions into the massive particle accelerator. The particles will be travelling at a relatively low energy at first of 450 GeV so that the operators of the can ensure that …

Solar Eclipses Are Slowly Disappearing, And There's Nothing We Can Do To Stop It

About twice a year, the Moon appears to pass in front of the Sun, giving rise to a partial solar eclipse if the alignment is imperfect, but leading to either a total or annular solar eclipse if the Earth, Moon and Sun all form a straight line in space.<p>It’s only by chance that the Moon and the Sun …
