Albert Einstein was one of the world’s most brilliant thinkers, influencing scientific thought immeasurably. He was also not shy about sharing his wisdom about other topics, writing essays, articles, letters, giving interviews and speeches. His opinions on social and intellectual issues that do not come from the world of physics give an insight into the spiritual and moral vision of the scientist, offering much to take to heart.  Continue reading

Computational physicist Sharon Glotzer is uncovering the rules by which complex collective phenomena emerge from simple building blocks. Continue reading

This has actually happened:
Anatoli Bugorski was a Russian physicist working at the  Institute for High Energy Physics on an accelerator called the  U-70 synchrotron. In 1978, he stuck his head inside the tube in order to diagnose a problem, when a safety mechanism failed, and the particle beam hit him in the head. Continue reading

Time crystals

Time crystals may sound like something from science fiction, having more to do with time travel or Dr. Who. These strange materials — in which atoms and molecules are arranged across space and time — are in fact quite real, and are opening up entirely new ways to think about the nature of matter. They also eventually may help protect information in futuristic devices known as quantum computers. Continue reading

Neurons in the brain

Consciousness appears to arise naturally as a result of a brain maximizing its information content. So says a group of scientists in Canada and France, which has studied how the electrical activity in people’s brains varies according to individuals’ conscious states. The researchers find that normal waking states are associated with maximum values of what they call a brain’s “entropy”.

One extra point (in general I agree with Alex Sergeev). I studied both in Russia and Israel (Technion – Israel analog of MIT – AFAIK Israel high education system is much closer to USA, many professors worked at some time in their careers in leading USA universities, many students do their docs / postdocs in USA etc). While textbooks generally speaking were better and “easier”, and courses materials were presented slower in Israel, teaching capabilities of professors and teaching assistants were much better in Russia.

OK, WTF Is a Time Crystal?

Physicists have made a new phase of matter called a time crystal—but what does that even mean?
