How one professor changed the culture of mathematics for his students
Later, as a professor, he noticed a pattern. Ardila’s Black, Latino, and women students who went on to Ph.D. programs also told stories of isolation and exclusion…so Ardila…set out to create, in his own classroom, a new kind of math environment.

円周率の計算で世界記録。62兆8000億桁を計算。スイス研究チーム
円周率の世界記録が更新されたと16日に発表された。記録を更新したのはスイスのグラウビュンデン応用科学大学の研究チームによるもので、スーパーコンピューター1台を使って円周率を62兆8000億桁まで計算したとしている。計算には108日9時間を要したという。これまでの「最も正確な円周率の値」は50兆桁だったそう。なお最後の10桁は「7817924264」であるそうだ。同大学の説明によれば、円周率の計算に関しては、数兆桁の知識を得ること自体よりも、この数列を正確に計算できるようにする手法が重要であるとしてい…
