According to quantum mechanics, our universe is like a Lego set. All matter particles, as well as particles such as light that act as messengers between them, come in discrete blocks of energy. By ...

The photoelectric effect is a phenomenon where light knocks electrons out of a material, resulting in the emission of these electrons, called photoelectrons. Albert Einstein explained the ...

How would Einstein have reacted to Bell’s theorem and the experimental results derived from it? Alain Aspect’s new ...

Although Einstein is a legendary figure in science for a large number of reasons — E = mc², the photoelectric effect, and the notion that the speed of light is a constant for everyone — his most ...

Albert Einstein, best known for his work in relativity, won the Nobel Prize for his formula for the photoelectric effect, which often surprises modern physicists. He's not the only physicist whose ...

Albert Einstein’s name has become shorthand for genius in theoretical physics. We tend to picture him scribbling equations about space and time, not tinkering in a workshop. Yet tucked alongside his ...
