By way of corollary, it adds: "That is why academic politics are so bitter." Sayre's law is named after Wallace Stanley Sayre (1905–1972), U.S. political scientist and professor at Columbia University. Academic politics is the most vicious and bitter form of politics, because the stakes are so low. https://en.wikipedia.org/wiki/Sayre%27s_law ---- **Hofstadter's Law:** It always takes longer than you expect, even when you take into account Hofstadter's Law. ---- **Akin's Laws of Spacecraft Design:** http://spacecraft.ssl.umd.edu/akins_laws.html ---- **Dunning-Kruger Effekt:** [[https://de.wikipedia.org/wiki/Dunning-Kruger-Effekt]] ---- **Gell-Mann amnesia effect:** [[https://en.wikipedia.org/wiki/Gell-Mann_amnesia_effect]] ---- **Brandolini's law: bullshit asymmetry principle** [[https://en.m.wikipedia.org/wiki/Brandolini%27s_law]] ---- **Knoll’s law of media accuracy:** https://effectiviology.com/knolls-law/ ---- * [[https://www.heise.de/tp/features/Debatte-ueber-Mathematikverachtung-3376475.html|Warum sind Menschen stolz darauf, nicht rechnen zu können?]] * [[https://www.heise.de/newsticker/meldung/Kommentar-Ein-Plaedoyer-fuer-die-aussaetzigen-Zauberer-3197127.html|Ein Plädoyer für die aussätzigen Zauberer]] ---- **Parkinson's law:** Work expands so as to fill the time available for its completion.\\ If you wait until the last minute, it only takes a minute to do. https://en.wikipedia.org/wiki/Parkinson%27s_law ===== Zitate ===== An expert is a man who has made all the mistakes which can be made in a very narrow field.  ~Niels Bohr If you don't make mistakes, you're not working on hard enough problems.  And that's a big mistake.  ~F.

He described how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: "What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man, very clever," said the old lady. "But it's turtles all the way down!" —Hawking, 1988[1] ---- * Alles, was es schon gibt, wenn du auf die Welt kommst, ist normal und üblich und gehört zum selbstverständlichen Funktionieren der Welt dazu. * Alles, was zwischen deinem 15. und 35. Lebensjahr erfunden wird, ist neu, aufregend und revolutionär und kann dir vielleicht zu einer beruflichen Laufbahn verhelfen. * Alles, was nach deinem 35. Lebensjahr erfunden wird, richtet sich gegen die natürliche Ordnung der Dinge. (Douglas Adams, Lachs im Zweifel) ---- **Managers in Hot Air Balloons** A man is flying in a hot air balloon and realizes he is lost. He reduces height and spots a man resting in a field down below. He lowers the balloon further and shouts: "Excuse me, can you help me? I promised a friend I would meet him an hour ago, but I don't know where I am." The man below says: "Yes. You are in a hot air balloon, hovering about thirty feet above this field. You are near 47 degrees North latitude, and 122.7 degrees West longitude." "You must be an engineer," says the balloonist. "I am," replies the surprised man. "How did you know?" "Well," says the balloonist, "everything you have told me is likely to be correct, and technically accurate, but I have no idea what to make of the information, and the fact is I am still lost." The man below says, "Interesting, you're a manager." "I am" replies the balloonist, "but how did you know?" "Well," says the man, "in spite of having an elevated view of all the surroundings, you don't know where you are, or where you are going. You have made a promise which you have no idea how to keep, and you expect me to solve your problem. The fact is you are in the exact same position you were in before we met, but now it is somehow my fault." ---- ===== Videos ===== * [[https://www.youtube.com/watch?v=oa6cHEJIjYI|Erfundene Sprachen]] * [[https://vimeo.com/20384187|All Tech’d Out: Computers in Schools - Inner Compass]] * [[https://www.youtube.com/watch?v=3m5qxZm_JqM&frags=pl%2Cwn|Front fell off]] * [[https://www.youtube.com/watch?v=TGwZVGKG30s|It's gone!]] ===== Random Stuff ===== * https://blogs.sciencemag.org/pipeline/archives/2010/02/23/things_i_wont_work_with_dioxygen_difluoride * https://blogs.sciencemag.org/pipeline/archives/2008/02/26/sand_wont_save_you_this_time
