Recent questions
What did Victor Hess discover in 1912?
Victor Hess discovered cosmic rays in 1912 while in a hot-air balloon three miles above the ground. This discovery challenged the understanding of reality and connected cosmic rays to radioactivity.
Who aimed to unify quantum mechanics and relativity?
Paul Dirac, a brilliant physicist, aimed to unify quantum mechanics and Einstein's theory of relativity in the late 1920s. His mathematical marvel, Dirac's equation, described atomic particles traveling at any speed and revealed the existence of antimatter.
What did Richard Feynman develop in the mid-20th century?
Richard Feynman developed the quantum electrodynamics (QED) theory in the mid-20th century, explaining how electrons interact and underpinning the laws of nature with unprecedented accuracy. His controversial version of QED, along with Julian Schwinger's contributions, led to a powerful theory that solved quantum electrodynamics.
Who proposed the theory of quarks in the 1960s?
Murray Gell-Mann, a child prodigy, proposed the theory of quarks in the 1960s. Working with Feynman at Caltech, he used group theory to organize subatomic particles into the Eightfold way, and his theory of quarks was confirmed by experiments at the Stanford Linear Accelerator in 1968.
What is the measurement problem in quantum mechanics?
The measurement problem in quantum mechanics troubles scientists, where atoms only appear in a specific place when measured by a conscious observer. This highlights the bizarre rules governing the atomic scale and prompts a reevaluation of the universe's fundamental principles, challenging notions of time, cause, and effect.
