    I'd really love to see some of the notebooks of the professors'. It would give people an idea into how those that can achieve high-end qualifications keep important information written in a compact yet effective form. Particularly, it would help me in my current studies now with such little confidence as to not know whether the notes I write will be enough as they are.
    Just an idea.

    You know, I have the feeling that when a similar serial is created a thousand years from now, they'll just log into Space Royal Society Internet Archival Unit 7-51U and retrieve e-mails.
    -"Well, Braidy! This is the oldest e-mail in the Space Royal Society archive! Here is Space President Nipsy's endorsement of the idea!"
    -"Wow, Keyth! I'd better close my White Gloves.app when handling this, so I don't damage the file."
    It won't be nearly as special.

    YESSS!! I saw the title in the notification on my phone, but didn't have time to watch it till now.
    So I had time to wonder:
    "The oldest objects at the Royal Society? Hmmm... Well, that could mean lots of things.. could be the oldest thing associated with the RS, could be the oldest man-made thing (maybe a book) they have in the archives, or it could be (and that would be rather cool) the oldest rock they've got. Actually, Brady probably will probably deal with only one of these categories in the video, but it *would* be quite interesting to hear about the others!"
    ...and you DID deal with both of the main categories I was hoping for!! Which makes me really happy for some reason :D

  • @GabdeVue
    @GabdeVue 8 лет назад

    I am just now realizing that they pulled out a tray right from under the shelf. many objects seem to be written accounts - but inbetween suddenly objects in a boxed form - i really, really would like to learn more about the organization of such a varied collection. And stuff like: are there trays under every shelf? How are the old books conserved? Who makes custom boxes for some of the items?? What kind of order are they in?
    At my university there was a whole branch on library architecture (and restauration) - since one can study this subject, i bet you can go endlessly in depth about these questions. But seriously, i would love to know more about the way things are conserved, organized, displayed!
    Thank you so much for these videos. I love the quality, the engaging talks, the knowledge and anecdotes!

    This is one of the real strengths of the English language, being able to read 350 year old books without any real problems. If I got to read a 350 year old Swedish text I wouldn't understand any of it as spelling and words would be arcane for a modern speaker. In fact, I saw some 100'ish year old text awhile ago and I could read it, but with _great_ difficulty.

    I'm curious about the oldest human-made object/document in the Royal Society. I know we have seen some books from the 1500s, but I believe I remember Brady mentioning that some of the books on the same shelf were from the 1400s. I love the space rocks and oldest Royal Society documents, but I'm extra curious about what other super old stuff is laying around there... It's all fascinating though!! Loving every minute of this channel!!

    This brings up an interesting idea.... what is the process for adding something to the archives? Like if a gift is given. How is it cataloged and placed?

    • @Ti133700N
      @Ti133700N 8 лет назад +4

      +fasfan I'd also be interested to know how they confirm that this is indeed the actual artifact. For example, what kind of tests did they run on that meteorite to make sure it was the chondrite meteorite that fell in 1976 (it probably included a bunch of carbon-14 dating tests) ?

    • @puupipo
      @puupipo 8 лет назад +2

      +fasfan Yes! I was just about to say the same. I think it would be interesting to see the path of an object from when it is given to the Royal Society to when it has become just another item in the collection.

    • @brachypelmasmith
      @brachypelmasmith 8 лет назад +1

      +Ti133700N Carbon dating wouldn't work. Carbon dating is good for recent (geologically speaking) organics (parts of something that was alive). IIRC the upper limit for it is around 50 000 years.

    • @Ti133700N
      @Ti133700N 8 лет назад +2

      brachypelmasmith
      Yea it looks like the half-life of C14 is 5,730 years and so the detection limit is about 50k years old. They can use other elements though, like Rubidium (87Rb) / Strontium (87Sr) or Potassium-40 / Argon-40 which can date objects up to 10 billion years old.

    I'm a geology grad student, so I may not know everything... But my understanding is that chrondrites are formed from original solar nebula material and are about 4.55 billion years old, not two and a half billion. So basically older than earth. Achondrites, on the other hand, are much younger (distinguished by a lack of little round "chondrules" in the rock. The oldest rocks you can touch are chondrites. The jack hills zircons are tiny mineral grains in sedimentary rocks from Australia and are about 4.4 billion years old, and are the oldest "terrestrial" or earth-made materials.

      +DrMrProfJacob The oldest rocks are a little bit younger than the age of the Earth: about 4 billion years old

      Luis López That's actually amazing. It doesn't seem like much because they're everywhere, and they don't look all that special but gosh, 4 billion years. We really take rocks for granite. ....sorry

      +DrMrProfJacob Mind you the earth"s crust is renewing itself continuously. The earth is in fact the most active planet in the solar system in that respect. Has to do with a meteorite smashing into proto-earth 4 billion years ago that still gives a lot of iron and heat in the core of our planet and the moon (that resulted from the debri of that collision) is constantly pulling on the planet as well, preventing it from cooling down. So, the result is that the earth's crust is renewing up to this day by vulcanism and plate tektonics. Most rocks you see are thus not much older that maybe 50 million to 2 billion years old. There are only 2 places on earth where it is older.

    there should be a joke about the color of the rock (grey), and its distance from humanity.

    I don't mean to troll, but isn't every rock on earth also "very, very old"?
    Of course a meteorite (fragment) is cool, but, er - yeah :D

      +Simon Vetter Yes, but not as old as that meteorite, counting from when they formed from their molten states.

      Ronald de Rooij Don't forget the radioactive material in the mantle and ore which also maintains the heat

      There are Earth rocks older than that meteorite. The oldest rock on Earth (that hasn't been re-melted or otherwise destroyed, although it has certainly undergone some metamorphic changes) is about 4 billion years (from Canada), while the oldest mineral fragment (a remnant of a rock that no longer exists) goes back a bit further (an Australian zircon). There have been meteors dated beyond that though, to the age of the Earth or a bit older (~4.5 billion years).
