Mathematician Proves Huge Result on ‘Dangerous’ Problem
WEBDec 11, 2019 · Lothar Collatz likely posed the eponymous conjecture in the 1930s. The problem sounds like a party trick. Pick a number, any number. If it’s odd, multiply it by 3 and add 1. If it’s even, divide it by 2. Now you have a new number. Apply the same rules to the new number. The conjecture is about what happens as you keep repeating the process.
How Gödel’s Proof Works - Quanta Magazine
WEBJul 14, 2020 · So the only prime factorization of 243,000,000 is 2 6 × 3 5 × 5 6, meaning there’s only one possible way to decode the Gödel number: the formula 0 = 0. Gödel then went one step further. A mathematical proof consists of a sequence of formulas. So Gödel gave every sequence of formulas a unique Gödel number too.
Why Are Plants Green? To Reduce the Noise in Photosynthesis.
WEBJul 30, 2020 · Plants ignore the most energy-rich part of sunlight because stability matters more than efficiency, according to a new model of photosynthesis. Land plants are green because their photosynthetic pigments reflect green light, even though those wavelengths hold the most energy. Scientists finally understand why. Olena Shmahalo/Quanta …

Physicists Create a Holographic Wormhole Using a Quantum …
WEBNov 30, 2022 · Physicists have purportedly created the first-ever wormhole, a kind of tunnel theorized in 1935 by Albert Einstein and Nathan Rosen that leads from one place to another by passing into an extra dimension of space. The wormhole emerged like a hologram out of quantum bits of information, or “qubits,” stored in tiny superconducting circuits.
