Obviously computers were out of reach, so lots of | integration tricks and awful rules of thumb in places. | RicoElectrico wrote: | I wonder why there are no tables in places there could be one - | like in the list of metal expansion coefficients or | gravitational acceleration by location. | mhh__ wrote: | People had books for that stuff back then, so I imagine it | wasn't worth the considerable effort typesetting them. | | I also have a book of data from way back, and since its still | fairly accurate, it's still alarmingly easier just to look | something up than Google it i.e. there doesn't seem to be one | repository for (say) resistivity coefficients in one place | alongside magnetic moments. | MaxLeiter wrote: | Huge long shot, but do you happened to have a copy of | Radargrammatry by Daniel Levine? | mhh__ wrote: | By the looks of googling, all of mine are about 30 years | older on average. They're mostly tripe, i.e. books that | aren't classics for a reason, but sometimes it's nice to see | engineering as done in the past (if I'm ever a billionaire | I'm going to buy a jet fighter just to get access to the | manuals and take it to bits) | | My earliest maths book was an algebra problems book from the | late 1800s but I gave it away to my maths teacher when I left | for university as recompense for not turning up and generally | being a shit student. | mhh__ wrote: | Just found a book on raytracing from 1951! | ffhhj wrote: | Also very interesting this NAVY manual on mechanical computers: | | https://archive.org/details/mechanical-computer-technical-ma... | | There is an old book on building analog computers at home, but I | can't remember the title. | fanf2 wrote: | There's lots of good information about the Trinity College clock | at http://trin-hosts.trin.cam.ac.uk/clock/main.php | | The current clock dates from 1910 (a few years after this book) | and it has a similar design to Big Ben's clock in the Palace of | Westminster. | zokier wrote: | While watchmaking has enjoyed great reneissance lately, I find it | curious that full-sized clockmaking still seems pretty dead | field, at least comparatively. There is no popular reimagings of | grandfather clocks or other household timepieces like there are | watches. ___________________________________________________________________ (page generated 2021-01-28 23:01 UTC)
