June 9, 2022, marks 117 years since Einstein published his groundbreaking paper on the photoelectric principle. The analysis was published on June 9, 1905, also known as Einstein’s “miracle year” ...

FRANKFURT. It is now exactly one hundred years ago that Albert Einstein was awarded the Nobel Prize in Physics for his work on the photoelectric effect. The jury had not yet really understood his ...

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 ...

However, with wavelengths of only 13 nanometers and high radiation intensities of several petawatt per square centimeter something else – at least with some atoms – happens: With xenon, a whole ...

Who is Einstein? This video explores the life and contributions of Albert Einstein, the renowned physicist known for ...

Physics professor Steve Carlip stands next to a bigger-than-life image in the Physics and Geology building of Albert Einstein riding a bike. Theories that Einstein published in 1905 have provided a ...

In a flash: artist's impression of the photoelectric effect. (Courtesy: Technical University of Vienna) Just 45 quintillionth of a second (45 attoseconds) is all it takes for a photon to liberate an ...

In the photoelectric effect, a photon ejects an electron from a material. Researchers have now used attosecond laser pulses to measure the time evolution of this effect in molecules. From their ...

Albert Einstein is easily one of the most recognizable people in history, and everybody thinks they know why. He's the guy who, in 1905, completely revolutionized physics, overthrowing the prior order ...
