Oh wow, it's amazing the detail of the model mountain. It never occurred to me someone would produce a 3D topography back then, certainly not to that degree of accuracy.
To make the layers, you would take a sheet material (typically card or plywood now - not sure what would have been used then) and just cut out the appropriate contours into it (but in negative) so you'd end up with a mould roughly the size of the box the model is stored in with a "valley" the shape of the mountain. probably rub some kind of fat or soap onto the surface to prevent sticking, then just pour in the plaster
Brady, could you do a video about Halley's Comet, when it was discovered by Halley in 1759 and its passes in 1835 and 1910? Maybe some drawings as well?
But of course Keith has climbed Arthur's Seat. I mean, obviously. I would not be surprised in the least if he flew around the world in a hot air balloon once. Seriously, Keith's backstory has to include some sort of adventurism (totally a word)
I don't have n° 4, but I know an actual time traveler, who could be convinced - by a small fee - to go back and take an actual picture of the boy after the shipwreck. Whould that help?
Arthur Seat is indeed an extinct volcano. When you walk up there, you pass through parts from which you can only see nature, and you wouldn't guess to be in the middle of Scotland's capital!
I wonder how accurate the thickness of the plaster layers is to the height of the hill. It looks like it's probably exaggerated, but is it to any kind of scale?
Generally, a topographical model would be to scale. If you're going to the trouble to make an accurate map/model, why wouldn't you make the 3rd dimension element accurate as well? This IS the Royal Society, sir! How dare you?!
That's a very clever solution and a great way to replicate the measurements of a topographical map. Thank you, I was puzzling out how on Earth that could be done. Much appreciated.
I was wondering if they might not have cut out the middle step there and simply made the wooden (presumably) original as a "negative" to start with. No more work, really, and saves a whole step.
I love how the boy is completely dry in all photos, including the one "in the water".
Congrats on the Doctor of Letters, Brady.

for all who are interested: it's written Schiehallion experiment
The last time I was this early, the boy was still on the boat.
Last time you were this early, your girlfriend was disappointed.

Photoshopping long before Photoshop even existed!
Was on Arthur's Seat today. 2spooky4me.
(It's a volcanic batholith as far as I know)
Keith is an outdoorsman and he's hard as nails.
I hear he is also posh as cushions
Yeah, that was a laugh. Keith is great, but I wouldn't take him for an outdoorsman.
Brady, could you do a video about Halley's Comet, when it was discovered by Halley in 1759 and its passes in 1835 and 1910? Maybe some drawings as well?
Great video as always, I hope someone with the missing card see this and send it to the Royal Society.
There has to be a GREAT story behind the adoption of the moniker "SlyPearTree"
Missing photo #4 is a retouched image of the boy and his buoy.
It is titled, "The Boy and His Buoy."

Brady, Sixty Symbols the experiment involving the plumb line!!

Excellent as always. Thank you.
Congratulations, Brady!

I miss you zogg! Your channel is incredible!

I went to Edinburgh a few years ago, it was just like trainspotting the movie.
Always fascinating.
Beef Island sound like a good place to wash up after a shipwreck.
Who's here from Vox?
mehhhh
nice one, doc
Love the video, hopefully #4 turns up :-)
Awesome!

Trading Cards! Collect them all!
can you do some vlogs on keith's everyday life. if you dont I might make a comic strip about it.
Cant wait to see "Dr Brady" enter his videos now wearing a smoking jacket Monocular, and a pipe.
I imagine they'll have made the model using layers of wood, then made a mould from that, then cast the plaster model :)

That was awesome :)
Are there any Pokemon on top of that hill?
How did they calibrate the plumbbob?
Nice Speedmaster ;-)
@Objectivity
Was Henry James ever a member of The Royal Society?
I was on Authur's Seat when I was 5!
I feel like I would get along well with Keith, I would love to have conversations at length with him!
Have they found number 4 by now? Maybe?
Did you get the #4 in the end?
Which room in the Royal Society are you both in? Looks pretty grand.
4:17 "..a nice maritime scene" of a shipwreck lol
Last time, I was this early.
Brady, what happened with your mouth at 2:02?
19th century photoshop; Amazing, it is.
I'll trade you my No.4 for a No.2
No.4 is a selfie with his drowning shipmates in the background.
Come on Brady, you are an Aussie - it's pronounced lef-tenant not loo-tenant !
vox anyone ?
