Some of the most important problems in network science, it turns out, are equivalent to problems in descriptive set theory, a field dedicated to sorting through infinity. Joseph Howlett reports: www.quantamagazine.org/a-new-bridge...
A New Bridge Links the Strange Math of Infinity to Computer Science | Quanta Magazine
Descriptive set theorists study the niche mathematics of infinity. Now, they’ve shown that their problems can be rewritten in the concrete language of algorithms.

Qui a inventé les formes géométriques, et pourquoi ?
C'est la question de Louane, 7 ans. Le mathématicien Étienne Ghys explique que les origines de la géométrie, dont le nom vient du grec ancien, remontent à l'Égypte antique.

Particles can have “spin,” “color” and “flavor.” To some, they might be formed from vibrating strings. Other researchers see them as holograms, just like space time.

It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more…
