Quantum mechanics (QM) is 100 years old. A survey posted today by Nature shows that physicists disagree "wildly" on the meaning of various central concepts in QM such as the wavefunction, an observer, even on what reality is. The same applies to QM interpretations.

Researchers from the KATRIN experiment have announced the most precise upper limit yet on the neutrino’s mass. At 0.45 electron volts (eV), it's half the previous limit, and marks a step toward answering one of particle physics’ longest-standing questions. 🧪⚛️ physicsworld.com/a/katrin-set...
