- In this design, we pay tribute to the ultimate reality check in physics: Schrödinger's cat!
- Erwin Schrödinger was a Nobel Prize-winning physicist. Other geniuses in this series include Nikola Tesla, Marie Curie and Isaac Newton.
Quantum mechanics has produced its share of weird ideas, not least of which is Schrödinger's cat, a famous thought experiment devised by Nobel Prize-winning physicist Erwin Schrödinger in 1935 to point out flaws in the Copenhagen Interpretation of quantum mechanics.
Albert Einstein, who was never completely comfortable with much of quantum mechanics, agreed with Schrödinger's point, writing to him: "You are the only contemporary physicist, besides Laue, who sees that one cannot get around the assumption of reality, if only one is honest." Learn more about what the famous thought experiment means.
If you're on board with Einstein and Schrödinger, shop from our Genius Series of tees, sweatshirts, posters and more. One of our designs pays tribute to Schrödinger's ultimate reality check (look for the cat) and his monumental equation, which was a landmark contribution to quantum mechanics.
Using permanent magnets may help to make nuclear fusion reactors simpler and more affordable.
- Nuclear fusion is the process of fusing atomic nuclei, which can unleash vast amounts of energy.
- Nuclear fusion reactors have existed for years, but none of them are able to sustainably produce energy.
- A new paper describes how permanent magnets can be used on stellarators to control the flow of super-hot plasma.
The physicist was both a gentleman and scholar.
- Robert Oppenheimer wrote a telling letter of recommendation for Richard Feynman in 1943.
- After praising Feynman's intellectual prowess, Oppenheimer used most of the ink discussing the strength of his character.
- The letter is a stark reminder of the importance of emotional intelligence.
Physicists propose using time crystals to bring about a quantum computing revolution.
- A team of scientists proposes using time crystals to power topological superconductors.
- The approach could lead to error-free quantum computers.
- Time crystals appear to break laws of physics.
