No degree of education or preparation can get you ready for what it's really like to look down at your home planet.
the Event Horizon Telescope team unveils strong magnetic fields spiraling at the edge of Milky Way’s central black hole, Sagittarius A*. This new image suggests that strong magnetic fields may be common to all black holes.

Taken just two days ago: Cracked and scarred Dione (top), w/ the rings and our favorite geysering moon, Enceladus, in the distance. And in a closeup from only 321 miles above the surface (bottom), a longing look at Dione’s wispy terrain, which we thought in Voyager days would be extruded ice but is not.
Cassini’s final Dione flyby will be in 2 months’ time on August 17. We are now in the end game. Prepare yourselves for the final goodbye …
Development and problem-solving skills don’t always align. Without managing a core model, endless efficient tools can paradoxically demand more.
『開発能力』と『問題解決能力』は必ずしも両立しない。どんなにfast-efficientなアプリやツールを無尽蔵に提供しても、それを統合するコアモデルをマネージメントできないと、データドリヴンにシステムがdiverseして、更にツールが必要になるという逆転現象に陥る

NASA’s James Webb Space Telescope’s new view of Cassiopeia A (Cas A) in near-infrared light is giving astronomers hints at the dynamical processes occurring within the supernova remnant. #JWST
Numpyで多重共線性 (multi-collinearity)を回避する。共分散行列に対し固有値分解を行うのが一般的なステップだが、linalg.eig()関数ではなくvariance_inflation_factor関数を使ってVIFの閾値で弾く方法で代替できそうだ
To avoid multicollinearity in Numpy, a common approach is to perform eigenvalue decomposition on the covariance matrix. However, an alternative method could be to use the `variance_inflation_factor` function instead of the `linalg.eig()` function, and filter out variables.

20,000 years ago, a star exploded here in the constellation Auriga. It left behind this incredible supernova remnant behind these dark dust clouds.
