Includes a variety of articles by Faculty and Members exploring the origins of the Second World War and the bias often built into state accounts; the Janus-like nature of mathematical dualities; and the troubling history and misuse of the term “moral hazard” in health insurance. Also features a transcript of Alondra Nelson’s remarks delivered on the occasion of her appointment as Deputy Director for Science and Society in the White House Office of Science and Technology Policy; and coverage of Avi Wigderson’s 2021 Abel Prize for foundational contributions to the field of the theory of computation.

TRAVEL 
Vaccinated travelers
or those who have recovered from Covid-19 in the last 3 months no longer need to quarantine upon return to New Jersey.

Unvaccinated travelers and residents entering New Jersey from any U.S. state or territory beyond the immediate region (New York, Connecticut, Pennsylvania, and Delaware) should self-quarantine for 10 days. Individuals who test negative on a viral test for Covid-19 obtained 3–5 days after returning, must self-quarantine for 7 full days.

Nils Aall Barricelli: The Italian-Norwegian Mathematician was a Genuine Original

"This is Barricelli’s universe," states science historian George Dyson in Cosmos, referring to Nils Barricelli, past IAS Member, who used the IAS computer to experiment with algorithms that simulate evolution.  "This is the universe we live in now. It’s the universe in which these machines are now doing all these things, including changing biology." 

Flares from the Milky Way’s Supermassive Black Hole

"Sgr A*, the 4.6-million-solar-mass black hole that lies at the center of the Milky Way, is normally a fairly quiet beast," but a new study by Lena Murchikova explores how in May 2019 it suddenly became substantially more active than usual, producing an unprecedented bright, near-infrared flare that lasted roughly 2.5 hours.
