We have a poster of Maryam Mirzakhani in the library. Unfortunately, it is not in the public area. Only employees can see it. This is a pity, because she is very inspiring. Unfortunately, she died much too early in 2017.
She won the Fields Medal in 2014 and gave the Guardian an interview:

The digital ranging system that measured the distance to the Apollo spacecraft
http://www.righto.com/2022/04/the-digital-ranging-system-that.html
The basic idea was to send a radio signal to the spacecraft and determine how long it takes to return. Since the signal traveled at the speed of light, the time delay gives the distance. The main problem is that due to the extreme distance to the spacecraft, a radar-like return pulse would be too weak. The ranging system solved this in two ways. First, a complex transponder on the spacecraft sent back an amplified signal. Second, instead of sending a pulse, the system transmitted a long pseudorandom bit sequence. By correlating this sequence over multiple seconds, a weak signal could be extracted from the noise.
In this blog post I explain this surprisingly-complex ranging system. Generating and correlating pseudorandom sequences was difficult with the transistor circuitry of the 1960s. The ranging codes had to be integrated with Apollo’s “Unified S-Band” communication system, which used high-frequency microwave signals. Onboard the spacecraft, a special frequency-multiplying transponder supported Doppler speed measurements. Finally, communicating with the spacecraft required a complex network of ground stations spanning the globe.

Not necessarily weird, but definitely exhibitionists.

It's to match with the piano.

It took you a while to find it, huh? 😉

Who is Richard Halley?
I would not advise you to go there for the book because those are the not revised drafts, and I do not have the time to upload the corrected version. If you like the theme, consider buying the book. The link is on my pinned post.
