Love how Brady started using the Hydrometer as a pointer when looking at the instructions.
I was waiting for Keith to just snatch it from him.

These videos make want to be a librarian.
no doubt
to bad its a secret order you are born into.
Now it's not SECRET order, thanks for that!

Came here to find this comment. Found it. Good job, team.
I'd like to see a video that shows Keith's day-to-day job, I guess he's not only rummaging around the libraries and archives, but has administrative and service-related tasks. Or did you do that already and I didn't realize? :)
I like these videos where the items where chosen in advance more than the white gloves of destiny. Keep up the great work dr. Brady.
Brady's laugh at 6:11 reminded me of the Happy Mask Salesman in Majora's Mask.
I think you're supposed to open it under water.
Atalinay I love you
Open what? I r confoozd

It's a refernce to Harry Potter and the Goblet of Fire where he had to open the golden egg underwater to hear the mermaid song.
Interesting video. Would be nice to see one (not an antique) in action so we can see how it works.
I came here from numberphile but this has slowly become my favorite channel from Brady.
Been drinking whisky watching these tonight, so this is right up my street!
On one of your channels you might consider the career of Francisco Jose de Caldas, the Colombian naturalist, executed 1816 and introduced to me by a Colombian family member by marriage. His remarkable career showed that he had to work out a lot of things for himself as he had little access to European science. He deserves much more recognition. Unfortunately I don't read Spanish and can only make educated guesses at what a Spanish publication means.
"They proceded therefore to" = The Most British Sentence Ever
ooooooooh dat tie do. I'm in love.
You should do a "Periodic Video" response to this one.
How would they do such measurements today etc...
It is still done in exactly the same way. You float a thingy with a scale in the liquid.
With smaller versions made of glass and filled with lead shot.
I love these.
How did the dodo bird s died in the middle of the night
Thanks for another great Egjectivity episode.
Brady and Keith, you make a great team, and the content and production are amazing. i really wish I could download every episode to play again when I'm not near wifi. The replay factor on your videos is quite high.
Keep up the interesting stuff!
Excellent video! I sell the modern version of these hydrometers, so it was interesting to see some of the history behind these instruments.
Is it possible to get a tour at the Royal Society with Keith? I would give anything in the world for it!
I would love to have an audiobook from keith
I think it is, I remember often hearing in old objectivity episodes saying that you can come see the items there (including Keith) for yourself.
Oooh! I wonder where they store Keith overnight? He probably has a display cabinet somewhere in the building.
Was expecting there to be a scene at a bar at the end
love the hydrometer
At 5:25 I discovered that the Japanese rock band “Mr. Children” are time travelers 😮
Super *precise - Your videos are amazing!!
5:09 Mr Children and Rev Mr Sheepshanks! You don't get names like that anymore.
"sir, your hygrometers... frankly, they're terrible."
Syke, upon hearing this, collapsed to the ground.
"...Syke?"
I'm sure Brady's forcing himself not to laugh at Keith's great puns :')
Howdy Dr. Haran, another great video! Thumbs up! I do hope that some work of John Harrison (the English clock maker) will be showcased at some point.
Brilliant
"Do I take it these are the winners?" "Yeah in a manny of speaking" ... A bit of awkwardness. "(He designed the winning instrument, got the prize if you like), and then he died"... Haha LOL!!
Yes, it's lovely that Michael Faraday's name was on that title page, but they totally missed the even more awesome fact that there was a guy on that page actually named Reverend Mister Sheepshanks. I mean, come on. Anyone named Reverend Mister Sheepshanks beats a mere Michael Faraday any day of the week!
I agree. (Dr) Haran, please dig up more information about Reverend Mister Sheepshanks!
It's probably this one: en.wikipedia.org/wiki/Richard_Sheepshanks A more colourful character than you might expect from his name: 'he had six children from a relationship with an Irish dancer', and one of his grandchildren was the painter Walter Sickert, alleged by some to be Jack the Ripper.
Those hydrometers must have tested a fair few gallons of mighty fine spirits, I guess it's possible some of the spirits of the time may still exist in shipwrecks or Keith's RS locked desk draw.
What a wonderful collection the Royal Society hold.
But how much does the float level change as the excise officer’s pocket fills with quid?
5:25 Mr. Children??
The weights "960" and "980" inside the smaller hydrometer box are swapped. Please, Keith, fix that.
This channel should be called boxjectivity.
Dear Dr. Haran, could you ask for some object related to prime numbers in the RS for a future video?
Thank you!
We've done that, kind of, via our crossover with Numberphile... th-cam.com/video/eAjMvpRMVDw/w-d-xo.html
Only 12 weeks away from the #100 milestone. Do you have anything special planned?
hey brady - have u ever broken anything during ur journeys thru the archives of the royal society?
That's quite an interesting instrument :-)
I am confused, how would information on the density alone accurately indicate the contents of a liquid? Would it not be able to be composed of any manner of mixed things, just in different proportions?
hindos Gottenberg you're right, but I guess they only needed to measure the alcohol content of distilled spirits, which are pretty much pure alcohol-water mixtures. Not sure about methanol, although anything intended for human consumption shouldn't contain any of that. Conversely, anything that's not for human consumption is not remotely taxed as much and so doesn't need accurate analysis.
Great video... If this where to be used at docks and import stations...something i dont quite understand... They would need the original (pre-fermentation) and the post fermented hydrometer reading to get an accurate mesure (abv %). Is it possible to measure alcohol content with only the final gravity ?
You're right, but if it's neutral spirit you are testing then it really doesn't matter since the starting material is just water, for which there is a standard for specific gravity. It would certainly be an inadequate measure for something like mixed spirits.
How would they make such smooth round things in one piece? I can only think of hydro-forming and I doubt they had those
Think of a traditional brass musical instrument like a trumpet, they make the bells and flares for those by starting with a tube and then drawing it out while it's spinning on a lathe. Look up the wikipedia article on "metal spinning", I think that's how it'd have been done.
Where is Keith from? Close to Manchester?
Do you have anything from circa 1780? I would like to see what the British were doing around the time of the American revolution.
I've used some hydrometers before, but never one that fancy
"Benjamin Sykes got the prize" - YAYY! "...and then he died." - :'(
Keith that was rude!
Golden Egg?
Poultry, London???
I was going to make a Harry Potter joke about putting it in water, but when I heard "hydrometer" I realised I wouldn't be doing that...
Please give this for 72 hours to Standupmaths. Just want to see what happens.
I have now dreams about Brady breaking golden eggs because their density is not right. I don't know if that is a good thing or not.
Thought he said the Egg Size Committee.
why do you fuck with my boxes ?! I like boxes !
would have enjoyed a little more detail but enjoyed it nevertheless.
Golden eggs? ... MORROWIND
Was "You know what I like most of all....boxes" double entendre?
is Keith alright? he looks out of sorts.
anyone else immediately think of Willy Wonka?
