Life and work

Beyel, son of a bookseller, studied at Polytechnicum of Zuric from 1872 to 1876. The following year he worked as engineer in the Swiss Northeastern Railway Company, Schweizerische Nordostbahn only for one year but he moved to Göttingen University in 1877 in order to study mathematics. Returned to Polytechnicum in Zurich, he was assistant of the professors Wilhelm Fiedler and Wilhelm Ritter. In 1882 he was awarded a doctorate from Zurich University and the following year the venia legendi from the Polytechnicum. He taught at Polytechnicum until his retirement in 1934.[1]

He was a prolific writer. His most known book, Der mathematische Gedanke in der Welt (The mathematical thinking in the world), reprinted still today, is described as a declaration of love to mathematics.[2] He also wrote several books and articles, mostly about geometry.

In addition to his mathematical work, he also published some articles about politics, literature and cinema. He was one of the founding members of the Swiss Association for Educational Cinematography (SAFU) in 1929.[3] He was supporter of the germanophilist association Stimmen im Sturm (Voices in the Storm).[4]

gollark: As far as I know ISPs can't see that you connect to your own LAN.
gollark: You may only ask dishonest questions.
gollark: VPNs prevent ISPs from seeing all this except possibly to some extent #3, but the VPN provider can still see it, and obviously whatever service you connect to has any information sent to it.
gollark: Anyway, with HTTPS being a thing basically everywhere and DNS over HTTPS existing, ISPs can only see:- unencrypted traffic from programs/services which don't use HTTPS or TLS- the *domains* you visit (*not* pages, and definitely not their contents, just domains) - DNS over HTTPS doesn't prevent this because as far as I know it's still in plaintext in HTTPS requestts- metadata about your connection/packets/whatever- also the IPs you visit, but the domains are arguably more useful anyway
gollark: On my (GNU/)Linux computing devices, which is all of my non-portable ones, I run dnscrypt-proxy, which acts as a local DNS server which runs my queries through DNS over HTTPS/DNS over TLS/DNSCrypt servers.
