  • Eh, maybe? It’s part of the fantasy-world-is-real trope. A spiritual successor to Narnia, but with adult characters. Or a predecessor to something like The Magicians. If you like these sorts of books, where the real world is part of the setting, then it may appeal. It’s almost Isekai.

    Honestly though, I’ve forgotten most of it. It’s a “read once” book.

    Read “Fred the Vampire Accountant” instead ;)




  • In my particular case, the purpose was testing the equipment over a target that I can use to confirm it is working as expected.

    But GPR in concrete can be used for all the purposes you mention. It can also be used to find voids, verify “as-built” drawings, etc. Some of our clients use it simply to avoid drilling into rebar when installing anchor bolts for shelving or whatever.

    My background isn’t concrete, so I don’t do the more advanced things with it :)




  • Funny story.

    Two decades years ago, when I first started working in arctic exploration, we were limited to how much weight we could take with us to our exploration camps. Most of us would decided on a couple of books to bring with us. But I didn’t want to bring books I wouldn’t like, because then I’ve wasted my weight allowance. So I brought that gold-coloured LotR copy with me and read it over and over, year over year. Probably read it at least once a summer for seven consecutive years. Sometimes in environments even more desolate than Mordor. Imagine reading it here.

    Later, I got a kindle and the weight problem sort of went away.







  • Neufeld’s von Braun book is great! It doesn’t pull any ethical punches – it’s almost clinical in the treatment of his early career opportunism within the Nazi regime.

    The bottom shelves are dedicated more to rocket science than human spaceflight, generally, which is why I don’t have Hadfield’s book. I met him once though. I did grad school in Planetary Science and got to meet quite a few astronauts and have a few beers.
