Estimating the globe has ½ meter diameter, mount Everest would be a 0.4mm bump (From the modern baseline shape ["sea level"], not the local prominence which is much smaller.), Which is about 3 sheets of typical 24pound bond office printer paper. The total deviation of the spheroid from a true phere would be 4mm.
If that globe is 24 inches in diameter at the equator, its polar diameter would be 23.921. Basically 2mm smaller. You'd be unlikely to notice. Even if it was made perfectly round (doubtful) its polar diameter is probably at least that much smaller now just from gravity causing sagging in the materials.
Hi Brady You will be pleased to know that Adelaide is alive and well, although a little chilly. Plenty of excellent red wine to keep us warm. Love your work.
I was that nerdy little 6-year-old who asked for a globe for Christmas, and proceded to study it for hours in her spare time. 😂 I imagine that it would be quite out of date by now, since it showed the USSR.
So true, so true! Not only the subject of globes, but the tone, the manner in wich they speak and the elegance of the camera work. Not only information or knowledge or even wisdom, but an eternal glimpse of what is a conversation between gentleman.
I have my dad's globe he used for high school geography in the 70s. It's slightly bigger than a football and beautifully made. Nothing I see in shops now compares to it, especially the ones that are purely decorative.
From a modern perspective it's very odd to imagine knowing roughly how big the earth is but not knowing entire parts of land, having incomplete maps which get updated whenever a new explorer brings back news and new maps made along the way.
I presume that's how the actual Earth works - it's why the Illuminati only allow us to dig down a few kilometres, but the forbidden South Pole is actually a straw connected to the liquor-filled Core
Maskelyne and Hutton were the first to measure the density, and hence mass of the Earth. Hutton invented contours to do the maths. See Schiehallion experiment
Fun fact: If the globe was the size of an egg, the crest would be the same thickness as the eggshell. Kind of amazing one eggshell thickness one way is molten lava, and one eggshell thickness the other way is -270°C space, and at center this wonderful living space.
Its interesting to think about; nature's wonders always occur at boundaries between two or more things. Because that is where interaction can take place and create/emerge new wonders with more complexity than the two objects have on their own, respectively. The boundary place is where energy can flow and do work. This applies the same to things like chemistry (think surface area for reactions) but also for the ecosphere of the earth.
There's one like this in the maritime museum in Sydney. I thought they might be the same but they have different bits filled in so they must be from slightly different eras.
The earth is only 30km different in shape out of 12000km in diameter that's only like 0.2% or on a one meter globe it's only a couple mm in your globe. I suggest the band around the middle where the two halves join is probably actually a towering mountain of a bulge at the middle compared to real life earth
It is true that most surface features of the earth are fairly tiny in comparison to its diameter. Even mt Everest isn't more than a slight dent most people would confuse for some stuck on dirt. However. I can't help but ponder how a 12 meter wide scale model would fair, then every km is at least 1 mm.
Let's see, google says that "according to NASA, Earth's radius at the equator is 3,963 miles (6,378 kilometers), while the radius at the poles is 3,950 miles (6,356 km)." That is a third of a percent. If that globe has a radius of about 30cm, the maximum difference in the largest and smallest radii would be 1mm. Nobody would notice.
I've got one of the little tin 6" moon globes created by Replogle during the years of the race to the moon. It has sites of the various lunar landings and missions marked, with the last one being in 1966. Interestingly, even at that date, the full moon had not been mapped and on the globe there is a blank "wedge" at the rear.

Matt Parker would be the perfect fit for calculating if it is possible to create a true representation of the earth in a globe. He could probably use his last hand-calculated 100 decimals of pi. 😊
If the Royal Society wants to impress me it will admit that Chimborazo is the world's highest mountain. Comparison to some local sea level doesn't impress me. The highest point is the furthest from the centre. If we can kick Pluto off the planet list, this should be trivial.
Can you make a video about Jones' Daedalus' perpetual motion machines and other life? Heard that Royal Society has one of them and that his life was interesring on Sideprojects channel, so it just might also grab a couple of views.
8:46 Those are, of course, the 1759 and 1835 returns of Halley's Comet. I am curious about the comet marked "1789". Is this alluding to Halley's (incorrect) prediction that the comet of 1661 would return that year? If so then that book probably got out of date quickly and in a rather embarrassing fashion. The first edition of Wright's book, printed in 1731, did not include the two comet orbits. From when is the print you've shown?
I am quite used to seeing "long" s glyphs in old printed stuff, but I still always imagine everyone in the 18th and 19th centuries "fpeaking with a filly voice"
The ſ was just an alternate way to write s mid-word, however the familiar form was still always used at the end of words or following a few other rules. It was common practice in old documents
Yes, Aristotle knew around 350BC, back when the "known world" of western civilization was Europe, some of Asia, and some of Africa . He added up a lot of evidence such as lunar eclipse observations, ships going over the horizon, time-based shadow angles/lengths in different cities, and a myriad other small bits. Many other cultures had a flat Earth in their mythologies, but none of them really fought the spherical concept as they moved into using evidence based science. Modern Flat Earth is actually very new, from the mid-1800s, based on incorrect interpretation of an already flawed experiment(the first version ignored things like atmospheric refraction, bringing the possibility of a Flat Earth within the observed error bars of the experiment).
@@BrianBlockNeill deGrasse Tyson, one of your gods, chucked out on a debate with Eric Dubay on Jo Rogan. Why? This would have reached a wide audience and let the real science win
Eratosthenes already calculated the size to within a few % as early as 250 years BC, only the really illiterate and backward folks didn’t know the earth was round.
New owner: "Why is it called an astronomical globe?"
Globe salesman: "Well , Sir , allow me to present you with our invoice."
Keith never misses. He was on fire on this one.

9:07 "My dear , would you like to come upstairs and inspect my orbs?"
Lovely banter, great information. Don't think I have seen an unfinished globe before.
Omg there’s finally a map that has the whole of New Zealand but no Australia yessss
Right?
Conversely /r/MapsWithoutNZ/
I love globes. I remember looking at one for hours as a child.

This may be some of the best wordplay ever in an Objectivity video.

I have a globe from about 1993, a gift from my grandfather and now shows the state of the world when I was little.
And Objectivity video with Brady and Keith! For 12 minutes and 4 seconds the world seems a bright and hopeful place again!
So true, so true!

5:15 The "Sandwich Islands" which include "Mowee" and "Woahoo".
That's where Mario lives
I saw this and had to look it up. apparently those are old names for the Hawaiian Islands.
Not “Peckish” and “Cucumber”?
@@peterfireflylund I prefer your version.
These must be alternate spellings approximating Maui and Oahu then
Matthew Flinders had mapped the southern coast by then, but he was imprisoned by the French for a few years in Maritius.
A well rounded video
I could sit here all day too! You could make these an hour each easily! Much love!
This Brady and Keith comedy routine was a bit of... Globe theatre!
From a modern perspective it's very odd to imagine knowing roughly how big the earth is but not knowing entire parts of land, having incomplete maps which get updated whenever a new explorer brings back news and new maps made along the way.
But does the globe open up and is there booze inside?
A proper globe would indeed 😂
They gotta keep some secrets. Membership has its privileges.
But could captain cook,cook?
How much wood
Would Captain Cook cook
If Captain Cook could cook wood?
I presume that's how the actual Earth works - it's why the Illuminati only allow us to dig down a few kilometres, but the forbidden South Pole is actually a straw connected to the liquor-filled Core
I so wanted that portrait of Cook to be the one on our old NZ bank notes, but not so.
Thanks to both presenters.
I have my grandfathers globe on my desk.
thankyou for producing this. thankyou to the RS.
5:13 I'm pleased you showed Banks Peninsular on the globe. (It was Banks Island at the time , because of incomplete surveying.)
A Brady channel I didn't know about?! Instant subscibe.
I love the Sun with a happy little face
ah, the repartee...."I imagine you have famous archivists hanging on *your* wall..."
My favorite brady channel next to numberphile. I need more Brady and Keith!
4:55 ohhhh boy I can see them running wild with this lol
Forget the globe, I want to see a video about the time machine that brought young Keith from that past to help present-day Keith with the carrying!
Nevil Maskelyne? The "bad guy" of the Longitude story? Had a globe dedicated to him?
Astronomer Royal. Invented and Implemented Lunars, which calculates longitude. I've performed them and they do function as advertised.
Maskelyne and Hutton were the first to measure the density, and hence mass of the Earth. Hutton invented contours to do the maths. See Schiehallion experiment
A classic!
Alright, everyone. Let's get a whip-round going to get Keith a bust of Zenodotus for his library.
In an unusual twist, this map does feature NZ

The smoothness of this globe is a relatively accurate , true to scale , representation of the Earth's surface

@@jaspertuin2073 Indeed, it’s a natural principle. Tell me you’ve studied Permaculture without telling me 🫵😉
My GGGGGgrandpa moved to Adelaide in 1839, while it was still a tent city.
There's one like this in the maritime museum in Sydney. I thought they might be the same but they have different bits filled in so they must be from slightly different eras.
Whenever I see an old map or globe, I check the accuracy of my childhood state of Michigan. It was pretty easy to mess up a bit.

The Netherlands always looks so different on old maps without Flevoland
4:52 At that scale: spherical is proper.
The oblateness is too slight. Not hundredths of an inch.
Yay Keith! ( I wonder if he ever got to see those emails I sent to him about the Royal Society featuring in CATS)
Can you share with us a little more about Keith's upcoming exhibit?
1:40 is that this globe in the painting?

You have a globe? Take me, I'm yours!!!!!
Joseph Banks also makes affordable suits.
Is that Brady Haran or Heston Blumenthal?
Does "Bar K.B." mean "Baron, Knight of Bath"? Based on what I'm seeing in Joseph's Wikipedia, it seems that is the case.

Why are only some of the lowercase s’s printed as f’s?
Well, I mean, come on Brady. It's not like Adelaide is real, right?
😉
8:15 the sun is actually a lion! I knew it!
A world without the Adelaide Crows, nice!
Where is the selection of spirits with crystal decanter and set of glasses? I'll say its incomplete!
it always amazes me just how recent 'modernity' is when I see how unknown Australia, Africa, and America used to be (to Europeans).
Some people would say that it needs to be flat. LOL
At that scale, I don't think you would be able to see any non-sphericality.
Why do the "s" letters in that little book he reads at the end look like f's?
That's just how they wrote it back then, bit confusing as the f's also are f's. :)

At that scale the sphere would be flattened by one millimeter or so. I doubt the sphere is made to that accuracy anyway 🙂
Keith: Flat earth, confirmed.
Video ends on a somewhat, shall we say, rainbow note.
Haha, at the end there it was less mansplaining than mansplaining fan fiction/fantasy. What an interesting insight into those times!
Well before NASA was established! Where's a flat earther when you want one.
Keith taking the pish out of ye olde mansplainers 😂👌
I think it’s time we had a “Mansplained by Keith” series
Never realized Keith wore Gucci specs. Very fancy!
new Holland is the better name of Australia. Australia should be renamed.
