Mathematicians Transcend Geometric Theory of Motion

By KELSEY HOUSTON-EDWARDS

More than 30 years ago, Andreas Floer changed geometry. Now, two mathematicians have finally figured out how to extend his revolutionary perspective.

New Brain Maps Can Predict Behaviors

By MONIQUE BROUILLETTE

Rapid advances in large-scale connectomics are beginning to spotlight the importance of individual variations in the neural circuitry. They also highlight the limitations of "wiring diagrams" alone.

DeepMind's Debut in Mathematics
Google's DeepMind has made its first significant contributions to pure mathematics, Stephanie Pappas reports for Live Science. It has introduced a new conjecture in knot theory and made progress in proving another from representation theory. Automated "theorem provers" have aided mathematicians for a while, and this new work shows that the field's use of AI is likely to increase in the future. In 2020 Stephen Ornes wrote for Quanta about the field's possibly AI-centered future.

Confronting a Quantum Clich├й 
The phrase "shut up and calculate" has long been used to deride physicists who adhere to the anti-realist Copenhagen interpretation of quantum mechanics. For Aeon, Jim Baggott clarifies that the early quantum pioneers in Copenhagen are not to blame for the "dogma of indifference" to the philosophy of quantum mechanics. Recently, researchers have had renewed interest in quantum theory's implications. In 2020 Anil Ananthaswamy reported for Quanta on a thought experiment that highlighted the peculiarities of quantum mechanics. This is one of a growing number of thought experiments (and real ones) aimed at demystifying the strangeness of the theory.
