Thanks to all of our viewers for tuning in to the past 200 episodes... Here's to 200 more!

I love how excited Keith is compared to Brady when he says "information...management systems..."

people have often said they could listen to Keith read the phone book. Well now it has happened.

This was a good choice for 200th episode. It may not be glamorous but it is special.

Congratulations on #200. Seeing all those irreplaceable documents all together made me think of how much would be lost if there was a fire, so how about an episode on the measures the Royal Society has taken to minimize such a risk. I also think it would be interested on what they did to protect their documents during the wars.

Information management systems. *In space!*

This is why we like Keith: presents stuff that we expect to bore us that inevitably draws us in...

I started watching somewhere around the 80s, and now I can't miss them. Whenever we are down in the archives I realise how many more potential episodes are possible. You could get to 1000 without breaking a sweat.

I love objectivity so much. Thanks for making it, James, Brady, Keith, and everyone else involved. It's the best!

I actually think information management systems are very interesting! I'd like to see more of keith talking about archiving and information!

Keith has outdone himself with this one!

Here's to 200 more.

Apart from being a lifetime achievement, this is a fantastic monument dedicated to traceability in science. It couldn't be more relevant for your 200th episode.. Congratulations for making it there and thank you very much, Brady..

You can tell that this collection absolutely pleases Keith. I think that is because the information is all complete. Nothing missing from the Herschel work. Which makes it very valuable for research and information. Wonderful to have at the Royal Society! Great episode Brady. 😁

Fantastic episode! Many thanks to Keith for bringing all those historic documents together in one place for viewing. Truly astounding to see the originals, if only on video. Congratulations on your 200th!

Keith and the Herschel's would have been great programmer/computer scientists.. Thank god they lived in a time and place when their strive for precision and excellence was put in another field when humanity needed it. Thanks for the 200 episodes! I'm looking forward for the next 200!

I wonder... did the Herschel's imagine that we would continue their sweeps of the skies to this day? How excited would they be to see our catalog today?!

That was brilliant! Literally a table full of raw science in its original form, like a physical time lapse of how astronomy is actually done.

"This is VERY exciting!" "Is it?" "Yeah, it really is - look at this mound of paper!" For Keith, too much is never enough! Congrats on #200 and a mound of Objectivities!

I think it's great to show that science isn't just about the nice clean results but that those results are built on hard, tedious work to gather data and that this is part of the process.

I'm a big fan of Brady and Keith (and James)! Thank you so much for bringing these many episodes and presenting the history of science (and so mankind) to us! This great trove of treasures would not be available to history lovers (like me) if it weren't for the thoughtful and articulate presentations you 3 have created! Thank you ever so!!

I'd be uncontrollably excited if this appeared in glorious detail on deep sky

Shame they didn't mention this formed the core of the New General Catalogue by Dreyer, which is still after various revisions the principal catalogue system for astronomy.

I love everything you do... but this one is very special to me! First, because I did lot's of amateur astronomy myself, but even more so, because it manages to perfectly distill the essence of 'objectivity', in making the world understand how important museums, librarys, libraryans..., or 'collections of informations and how they are managed', really are! Before 'objectivity' I rarely ever thought about 'libraryans' as more than the people, putting the books back to the shelves they belonged, once I returned them. or charging me the late fee, whenever I forgot to. That I never thought about it is quite odd, given the fact, that I read hundreds of books lend from a public library and happened to be there once to twice a week back before there was internet. It took me many years to understand how much and how unnoticed, those Libraryans had managed to contribute so much to my otherwise quite poor education. Driven by boredom that couldn't be filled by three television channels alone, I was searching for 'sci-fi pulp', 'adventure' and other types of preferably easy and meaningless 'dream fullfillment', yet those sneaky Libraryans somehow managed to smuggle books considered 'higher literature' on to my reading list, again and again and again... Back than, I sometimes felt kind of 'cheated' when, what I hoped to be a space opera, turned out to be so much more than this. Nowdays I'm often amused, when realizing that I read some book considered 'influential literature one has to read', back when I was twelve, since how should I have known back than that 'brave new world', 'fahrenheidt 451', 'solaris'..., are not 'space opera', even so it says 'sci-fi' on the cover and that 'the catle' does not feature a single knight? 'young adult fiction' wasnt't a thing back than, since libraryans hadn't come around to make it one yet. 'sci-fi' & 'adventure' where considered 'trash' and the corresponding library department was small. At some point I had read all the ones I found compelling and ended up reading James Joyce, E.T.A. Hoffman, Kafka, George Orwell... instead. Today I work right at the bleeding etch of it-industry, often in a position, that was supposed to be filled by an academic, without ever attending any kind of 'higher education' myself. Although Having 'properly' learned two other professions, everything important I ever knew, is what I thought myself. The library, the libraryans that worked there and the choices they made, played a huge role in making that possible. So thanks to all the libraryans, that not only improved my personal life, but in defining what 'civilization' even means and how it needs to be labeled and stored properly, play such a huge and largely underestimated role in keeping it. A very special thanks therefore goes to Keith Moore, who helped a lot in making me understand that role and to Brady Haran of course, for producing and promoting such excellent content on a platform, that could really need some professional help in managing it.

Fantastic episode Brady! Congrats on bringing up the double century.

When Brady said "I hope Carolyn gets a mention somewhere in here", my brain was immediately like - "Ctrl + F dude...."

Love seeing Keith so excited! :)

I love this channel so much i go back and watch the older ones all the time to get my fix.

What a very fitting topic for #200 (and gratulations, Brady, you still make the best content ever on YT) - shame there were so very few pictures involved, wasn't it :P

What a beautiful take on science history! Thanks so much for sharing and congratulations on reaching #200!

Brady, I don't comment here often but I have to say that I'm extremely happy that you took me with you to see all of this wonderful objects. I've been subscribed since the very start, the amount of joy that this channel gave me is immessurable. Thanks for being who you are and doing what you do; I'd love to have a pint with you. Please thank Keith for his work on our behalf.

200!! Congratulations!! I remember binging the first episodes back in the beginning of '15 when I was practically glued to my bed because of back pain. Luckily the back pain has gone, but Objectivity remains! Love the channel and I'll never get enough of Keith being quietly excited over old papers

Congrats on the 200th awesome episode!

Loved every single one. Keep making more please! Cheers to Keith. Next haircut I'm getting a "Keith"

Congrats on #200!

8:07 OMG. I love that font!

Loving this channel. Its absolutely brilliant to see objects that are actually attached to history 😊

Great 200th entry! Big thanks to Keith and Brady for this treat!

A very nice subject for the 200th episode. Hope there are 200 or more to come.

Please add more people than mathematicians to your interview podcast! I'd love to listen to Keith talk for hours about how he came to be the librarian to end all librarians!

Actually, this exceeded my expectations for how fun it could be hearing about it. Well done and nicely played!

Congrats on 200. That second series of documents is exactly what we would call a "view" or just a "result set" from a query on a modern relational database. SQL lets you select whole or partial records that match some criteria, as well as order them. Today in 2019 such queries to take milliseconds... it is mind-numbing to think about the weeks and weeks it must have taken to comb through that original data and organize it in the new format.

Thank you for all the effort you put out to create such quality content.

I... am... astounded.. Fabulous!

I haven't watched this channel in years, good to see Keith is still causing a ruckus, what a lad

Truly awesome. Great video, and fantastic storytelling.

Excellent. You're both gems.

And now we can look at an image of a black hole, at the center of one of those nebulae.... BTW, what did the Herschels see at the M87? Thank you for the last 200, looking forward to the next 200!

Episode 200! Thanks to one and all!

Keith pulled a blinder there! Well done Keith.

Oh man this is so amazing, I so would love to go through one of the catalogues myself.

This was a pretty good one for not having too many pictures.

happy 200th objectivity!

I remember watching the 100th episode of objectivity that one about isaac newton was fantastic

Oh Brady! That you would stand before the very writings of the Ancient Ones and not collapse in awe of the mysterium tremendum et facinans! I will light a candle for you and attempt the appropriate propitiation on your behalf.

Congratulations!

Brilliant!

Wow, that is an amazing set of documents.

An episode worthy of publication.

Fascinating

When Brady's Channels Collide! More mash-ups, please!

Marvellous!

How dare you doubt Keith, Brady

Facinating

I noticed that so much of the information is in cursive and it is extremely well done. Today most kids are not even taught cursive writing, much less the beautiful style shown here.

Perfect for #200

Perfect indeed

Keith is great! When he says it is "read to the royal society" was it actually read? did anyone listen?

Love the tie

I would think the size given for the telescopes would be focal length as opposed to objective diameter. I'll have to check out Brady's Messier channel when I get my scope out. I never could get the equatorial drive properly aligned.

Brady, could you arrange for some recordings of Keith reading old documents to appear on iTunes?

on the way to 1M!

Keith is my kind of librarian.

I have to assume the “ten foot” telescope refers to the focal length? It can’t refer to the mirror diameter.

Also is there an episode on book binding? I am doing a zine right now and I had a half a year course in bookbinding at school as well but I would love to hear the archivists perspective. In our local museum there are many many history books hand done and I could see the binding technique being pretty much what we learned in school for hardcover. But what about Coptic binding or Egypt etc?

Congrats! My mom would have created an index like that. Come to think of it, so would I.

great episode. do you think Cave painting artists has assistants?

I could listen to keth all day reading anyone else

"[...] in Slough" I feel sorry for them, if Tom Scott taught me anything about Slough

Makes me appreciate spreadsheet software a while lot more

It is interesting to see how human being these old scientists are. He got a new telescope, and of course, he preceded to play with it for a whole night

I'd like to read Herschel's description of Messier 73 (GC 4617). Not being a nebula at all, Herschel must have been reluctant to include it, but eventually did.

0:31 Nice bit of knolling by Keith!

Herschel's assistant wasn't mentioned, because... *assistants were never mentioned!*

I will be here to see the 1000th one

yeah, perfect.

I'm still bitter that Sol 7 was named Uranus and not Herschel.

So, what do we know about star/nebula #200?

What are the best digital catalogs available today?

Happy Bicentennial Episode!

I was hoping for 200 minutes of Information management systems!

John Herchall used a spreadsheet!

Just think what all the autographs in the collection must be worth......heaps.

3:11 Oh, nice handwriting (for once)!

he's a librarian, information management systems are kind of his deal.

@ 2:45: Does anyone happen to know why wood is bad for storing papers over time? Is it just because it stains the outer sheets? Google is giving me twoddle

200th!

More like an address book than a phone book, no?

🎊🎉🎊
