Electric power generation from Earth's rotation through its own magnetic field (arxiv.org)
Earth rotates through the axisymmetric part of its own magnetic field, but a simple proof shows that it is impossible to use this to generate electricity in a conductor rotating with this http URL, we previously identified implicit assumptions underlying this proof and showed theoretically that these could be violated and the proof circumvented.
Can Musk put people on Mars? (economist.com)
HUMAN LAWS can be changed, waived or broken. Physical laws are less biddable. When it comes to putting humans on Mars, which he sees as the first step towards the planet’s settlement and humankind’s salvation, Elon Musk now has little to worry about from human law.
Symmetry between up and down quarks is more broken than expected (phys.org)
In late 2023, Wojciech Brylinski was analyzing data from the NA61/SHINE collaboration at CERN for his thesis when he noticed an unexpected anomaly—a strikingly large imbalance between charged and neutral kaons in argon–scandium collisions.
