And now I have learnt it. I understand orbifolds and the group theory necessary to prove Conway's theorem. I have proved the theorem myself, and the corollary that there are only seventeen periodic tessellations of the plane. I still like the subject a lot and I am happy to have written my bachelor thesis about it.
What academia should always be and feel like.

Bei manchen Autofahrern blitze es aber auch gleich zweimal. So fuhr ein Raser in Dortmund mit Tempo 96 statt 50 in eine Kontrollstelle. Dabei wurde festgestellt, dass er seine Kraftfahrzeug-Steuer nicht bezahlt hatte. Mit quietschenden Reifen fuhr er wutentbrannt davon - und landete mit Tempo 78 direkt in der nächsten Tempofalle. Macht zusammen 230 Euro Geldbuße, vier Punkte in Flensburg und einen Monat Fahrverbot.

DRM-HTML.
A Web where you cannot cut and paste text; where your browser can't "Save As..." an image; where the "allowed" uses of saved files are monitored beyond the browser; where JavaScript is sealed away in opaque tombs; and maybe even where we can no longer effectively "View Source" on some sites, is a very different Web from the one we have today. It's a Web where user agents—browsers—must navigate a nest of enforced duties every time they visit a page. It's a place where the next Tim Berners-Lee or Mozilla, if they were building a new browser from scratch, couldn't just look up the details of all the "Web" technologies. They'd have to negotiate and sign compliance agreements with a raft of DRM providers just to be fully standards-compliant and interoperable.
