ブラックホールが恒星と融合し超新星となった可能性が調査により示される
高密度で強い重力を持ち、光さえも飲み込んでしまう天体がブラックホールです。そんなブラックホールが宇宙に浮かぶ星を約300年かけて吸収して崩壊させ、超新星爆発を引き起こした可能性があることが調査により示されました。 A transient radio source consistent with a merger-triggered core collapse supernova https://www.science.org/doi/10.1126/science.abg6037 Star Explodes After Black Hole Devours It From the Inside https://www.newsweek.com/star-explodes-black-hole-devours-inside-1625720 天文学者のディロン・ドン氏らは、2017年に観測され

国会事故調査委員会（東京電力福島原子力発電所・事故調査委員会）http://www.naiic.jp/が、５日、報告書を発表した。 この件について、ツイッターを通じて感想を出してきたのだが、記録のために、ブログにも記しておこうと思う。報告書の英文に、日本人一人ひとりにとって、宿題のようなことが入っているのに対し、日本語原文のほうには入っていないように見受けられるからだ。 まずお断りしておきたいのが、私は日本に住んでいらっしゃるみなさんほど、原発事故や福島についての詳細な情報を把握していない。また、６００ページ余ある報告書本編の全部をまだ読んでいない。 それでもここで書いておこうと思ったのは、報告書の最初のほうにある委員会の黒川委員長の言葉から、原発事故のみならず、日本の現状や将来について、また私が書いてきたメディアの世界について、深く学ぶことが多いと思ったからだーーある意味では、原発や震災

The jeering of Prime Minister Shinzo Abe is ''almost unheard-of behaviour'' at a war commemoration in Japan, as Rupert Wingfield-Hayes reports Japanese PM Shinzo Abe has been heckled at a ceremony marking the 70th anniversary of the Battle of Okinawa.

Timsort is a hybrid, stable sorting algorithm, derived from merge sort and insertion sort, designed to perform well on many kinds of real-world data. It was implemented by Tim Peters in 2002 for use in the Python programming language. The algorithm finds subsequences of the data that are already ordered (runs) and uses them to sort the remainder more efficiently. This is done by merging runs until
