What's up in
Mathematicians and computer scientists answered major questions in topology, set theory and even physics, even as computers continued to grow more capable.
Puzzling particles, quirky (and controversial) quantum computers, and one of the most ambitious science experiments in history marked the year’s milestones.
The detailed understanding of brains and multicellular bodies reached new heights this year, while the genomes of the COVID-19 virus and various organisms yielded more surprises.
Online comment platforms can bring out the best — and the worst — in people. At the end of a tumultuous year, Quanta’s editors highlight some of our favorite things you had to say.
While the study of the SARS-CoV-2 virus was the most urgent priority, biologists also learned more about how brains process information, how to define individuality and why sleep deprivation kills.
Even as mathematicians and computer scientists proved big results in computational complexity, number theory and geometry, computers proved themselves increasingly indispensable in mathematics.
Featuring paradoxical black holes, room-temperature superconductors and a new escape from the prison of time.
Physicists saw a black hole for the first time, debated the expansion rate of the universe, pondered the origin of time and modeled the end of clouds.
Researchers explored the zone between life and death, charted the mind’s system for arranging ideas and memories and learned how life’s complexity emerged.
