A couple of great ones are gone: Katherine Johnson and Freeman Dyson

Just under a week ago, we lost Katherine Johnson:

She was one of a group of black women mathematicians at NASA and its predecessor who were celebrated in the 2016 movie “Hidden Figures.”

PZ has written more about her here.

Today, we have lost another important figure – this one more well know and celebrated through his working life.

Freeman Dyson, quantum physicist who imagined alien megastructures, has died at 96 (livescience link)

Freeman Dyson, like so many scientists before him, did some brilliant work, and the turned towards less scientific ideas. This shouldn’t make you dismiss his importance, just make you weary of his later works.


Goodbye Rutger Hauer

I know I am a couple of days late, but as most of you probably know by now, Rutger Hauer passed away a few days ago, 75 years old.

Rutger Hauer is most well known for his role as the replicant Roy Batty in Blade Runner, which he played masterfully. One of his many great scenes in the movie, and perhaps the most famous, was his death scene.

The most amazing part of that monologue at the end, is that Hauer wrote it himself, apparently not being happy with the scene as it was written in the script.

While his role as Roy Batty was incredible, and well worth remembering, I also remember him from many other movies:

The Hitcher, Escape from Sobibor, Ladyhawke, the Blood of Heroes, Wedlock, Split Second, Buffy the Vampire Slayer, Fatherland, and Sin City. While most of these movies aren’t great movies (Ladyhawke very much the exception), Rutger Hauer gave his all, and made his roles memorable, and the movies entertaining.

Oh, as an aside, it should be mentioned, that Blade Runner was set in 2019, so Roy Batty died that year. Something fans obviously noticed straight away when Rutger Hauer died.

RIP Joe Armstrong, the author of Erlang

Sad news from the world of programming, Joe Armstrong, one of the authors of the Erlang language has died

I never worked much with Erlang, and have never met Joe Armstrong, but from everything I hear, he was a genuinely nice man.

If you want to know more about Erlang, and how it was used, you can watch Erlang the Movie.

To be honest, I highly doubt anyone outside the world of programming will get much out of that clip, but it is interesting to watch, since it shows what type of problems Erlang was developed to solve. It gives a view into the early days of digitizing telephony, which wasn’t that long ago, considered how long telephones and other forms of telecommunication has been around.
