What if, just before we reach the bottom, we find out that reductionism fails? Big things are made of smaller things, and those smaller things are made of smaller things still. That’s reductionism in ...

Researchers from the Austrian Academy of Sciences and the University of Vienna have demonstrated a precise method for reversing time in a quantum system, achieving an average fidelity of more than 95% ...

A former “D” student from Norway, he made his mark at G.E.’s Research Lab in the U.S., in part by confirming a pivotal theory about superconductivity. By Dylan Loeb McClain Ivar Giaever might not have ...
