It seems to me that we are currently experiencing the birth of a new discipline: mathematics engineering.
The theoretical physicist Rafael Sorkin died on September 12, 2026, at his home in Kitchener, Ontario.
He is best known as one of the main developers of causal set theory, an approach to the emergence of spacetime from discrete points. Nearly a decade before the accelerating expansion of the universe was discovered in 1998, he predicted that causal sets would give rise to an "everpresent" cosmological constant. He also introduced entanglement entropy as a possible explanation for black hole entropy.
