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 ...

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 ...

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 ...

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” ...

One of Canada’s most wanted killers, Robby al-Khalil, arrested in Qatar ’60s rock guitarist dies aged 78 Carney unveils billions in funding, Buy Canada policy to combat Trump's tariffs Fans remain ...

The dynamics of electrons changes ever so slightly on each interaction with a photon. Physicists have now measured such interplay in its arguably purest form -- by recording the attosecond-scale time ...

MURRAY HILL, N.J. (WHTM) — On this day in 1954, Bell Telephone Laboratories demonstrated the first practical solar panel. The emphasis here is on practical. The photovoltaic (or photoelectric) effect, ...
