At Symmetry Magazine: Quantum field theory is rife with something mathematicians can’t stand: unresolved infinities. In a 1977 essay, Nobel Laureate Steven Weinberg wrote that “[Quantum field theory’s] reputation among physicists suffered frequent fluctuations… at times dropping so low that quantum field theory came close to be[ing] abandoned altogether.” (But it was kept because it works. And what might that point to?)
Huyett: “As a graduate student in the 1950s, [Hugh] Everett was alarmed to discover that traditional quantum mechanics did not line up with his materialist commitments. He was repulsed by the fact that the human mind seemed to be given a special role—a conclusion that Everett thought smacked of the supernatural. ” So he set out to change the approach via his Many Worlds hypothesis.
At Quanta: In a paper posted online and submitted to Physical Review Letters, a group of quantum physicists in India and Poland demonstrates that it is possible to arrange 36 officers in a way that fulfills Euler’s criteria — so long as the officers can have a quantum mixture of ranks and regiments.
