The high-stakes race to make quantum computers work

Quantum computers could eventually outstrip the computational limits of classical computers. They rely on the behavior of atomic and subatomic particles, whose quantum states are incredibly fragile and easily destroyed— which is why this technology remains largely theoretical. How would quantum computers work, and are they really possible? Chiara Decaroli investigates. [TED Ed]

Einstein’s Biggest Blunder, Explained

This video is about how Albert Einstein made a mistake when applying the Field Equations of General Relativity to cosmology (in particular, to a static, constant density universe), and solved the problem by introducing the cosmological constant, rather than allowing for a dynamic universe with a scale factor – that is, the Friedmann-Lemaitre-Robertson-Walker universe, first […]
