6:30 Trying to make a map of the Milky Way from INSIDE the Milky way is a bit like trying to make a floor plane of some huge building while you're locked in a broom closet.
8:38, could they have used the 'pirate' method, of keeping an eye patch over one eye? You could sketch at candle light, with your telescope eye covered, or closed, extinguish the flame, and continue. Somehow I doubt they just memorised it long enough to sketch out such detailed drawings.
I find it incredibly fascinating to get these looks into the thinking process of those very intelligent people from a different time. There are so many things that these days we can't imagine to be any other way but if you see this, it makes you aware how much knowledge we absorb from early childhood. It doesn't matter how little someone knows these days about astronomy. Nobody would draw a rectangular structure when asked what they think the Milky Way looks like. Yet at some point, it seems to have been an obvious solution.
I think the German astronomer who named Uranus didn't think that far xD Although that "pun" or what you want to call it, does not exist in the German language, so the name is actually not funny at all in Germany (which proves that Germans still have no humor...)
They just glossed over the most amazing thing. Astronomers made negative pencil drawings of their observations, and had to either do it in the dark, or remember it *EXACTLY* to recreate it when they later had light. That's simply staggering.
This is my favourite video on the channel, I have revisited it several times. It’s just so fascinating to see how Herschel tried to visualise the constructions of the heavens. Imagine how captivating it was to uncover this in his time. Nowadays we almost take it for granted. I wish I could show Herschel and his son these pictures from Hubble. I wish I could have seen the look on his face when he came to know that some of these ‘milky nebulosites’ were actually entire constructions of starts like our own Milky Way. How vast the universe is. But alas.
The direction labeling on the M-94 drawing shows n, p, s, f, around the edges. The n and s are for north and south. So what's up with the p and f? This indicates 'preceding' and 'following.' Instead of east and west, these directions relate to the Earth's rotation. If your telescope does not counter the Earth's turning, the objects in the scope will drift across the view. So the 'p' side of the drawing are the preceding objects about to drift out of view, and the 'f' side are the following objects coming into the eyepiece view. This eliminates any mistaking directions as different telescope optical designs will flip and/or rotate the image as compared to it's appearance in the sky.
That Medal has Uranus named "Herschel" still, so I wonder if it was something he had made as a momento of "all the knowledge of the solar system to his present day" that he could give out to his colleagues, sort of as an advertising pamphlet to get support for naming the 7th planet after himself. Sort of leveraging the idea that once you see something written down, it must be true. Especially if it's carved into metal.
I wonder what happened to it. Could it have been in a fire? Did it suffer corrosion? Exposed to acid, maybe in an attempt to clean it? Or a galvanic reaction with another metal, perhaps its little box?
One of my favorite professors was a primatologist who was trained as a medical illustrator. He hand drew his entire text book for our class which we picked up copies off from the University print office. He had a degree in both veterinary medicine and art. The value of explanatory drawing done by someone who knows both the science and art of a subject is inestimable.
There's a special fragility with those first fuzzy observations that I find extremely poetic. There is so much meaning behind faint specks that barely exist.
Fantastic documents. Very creative and innovative attempts to project complex astronomical distributions. A thrilling feeling, watching the video here in Datchet, to see Herschel's paperwork with the date showing that, almost 232 years ago, to the day, he, also, was here.
Wow, 99 videos in nearly 2 years. I remember the first one as if it was... well... about 2 years ago. I bet they never thought they'd still be going 2 years later.
Could the medal that the end of the video be for an early projection device? Similar to how you can project the sun onto a wall with a telescope, perhaps the medal could take the place of the mirror in a telescope to project the educational image onto a wall for display? It just looked like it used to be very reflective in the past. Just a guess!
These people are simply amazing! I loved too much the way each one of them gives his personal contribution to the spread of knowledge, you guys make many people feel the passion for science. Love, keep up the good work!
Which field could you go in today to do stuff like this. Just looking up at the stars and charting stuff, being the first to, like 20 times every night. It feels like nowadays you'd have to have several degrees and spend years scouring just to go "yeah, that tiiiiny speck, the 77.552nd on the left? That's mine" or "I redefined the orbit of exoplanet HD 55486 j to 8 digits instead of just 7".
Someone commented that the dumbell nebula has expanded since Herschel's drawing of it there. I would like to see how much it has expanded. Is there a way you could overlay the drawing and a modern image? Are there reference points in the drawing that can be found in today's images?
how very cool. Portuguese being my first language I never realised that Via Lactea was not the main way to refer to the Milky Way in english as well, despite knowing the milky way title
I always kinda hate astronomy and biology in the same manner as I hate painting and stuff, the better the equipment available to you the more you can achieve with it in these fields. That's why math and literature are so much more appealing to me. (But even I gotta admit, sitting and observing the galaxy's stars and figuring out their relative positions sounds fascinating)
I love it how the scientific enthusiasm and astronomy knowledge of Merrifield complements Keith's passion for these objects. Perfect match. EDIT Man, Merrifield had me laughing when deducing that card image to Messier 64!
Another great video! I must've binge watched everything on this channel in the last two weeks, keep up the great work. I recently read that Daniel Gabriel Fahrenheit was also a Fellow, did you already do a video on him that I somehow missed? If not, any reason why there isn't one (yet)? Also, please say hi to Keith for me.
2:15 That pronunciation was actually pretty good. They almost sounded like native Spanish / Catalan speakers (except for the hard "v", ^^). I have to say, though, professor Merrifield was only half correct there. "Lactea" doesn't mean "milk", it means "milky" (related to milk / milk-like). The Latin for "milk" is "lac"/ "lacte". Also, "via" can be translated as "path", "way", "street", etc., not just "road". The old Latin name for our galaxy is still being used today by Romance speakers. Portuguese -----> Via Láctea Catalan -------------> Via Làctea Occitan --------------> Via Lactèa (aka "Camin de Sant Jacme" / "Camin de Sant Jaume" / "Chamin de Sant Jaume" / "Camin de Sent Jaques", which translate as "St. James' way / path / road" ) Spanish ------------> Vía Láctea Galician -------------> Vía Láctea Italian ---------------> Via Lattea Corsican -----------> Via Lattica French --------------> Voie Lactée Romanian ---------> Calea Lactee Great channel, btw!
Great episode, as always, but I have to admit, I really don't understand how Herschel's map should be interpreted. I have seen the map many times, going back at least to my intro astronomy course back in '92, but I still don't get how it translates into 3d, or what the perspective is. (top down, looking at the galaxy? Perspective looking around the whole night sky? :dunno: )
Visualize the galaxy as being in the horizontal plane, then this is one of many possible vertical cuts through it, that goes through earth. So he took a section of the sky that goes around 360 degrees with equal width, like the space between two parralel circles, that cuts through the milky way at 90 degree angles. The more stars he counted, the further out the map goes. So he got some things wrong because a cluster of stars that happens to be inside the area where he counted the stars causes a spike, and obfuscation issues he was unaware of cause a dip, but its impressive that he got some things right, given that he had no way of measuring the distance of these stars.
I like the the then and now images of galaxies etc. amazing the advances in technology which sadly has not extended to the imagery we get from the mars landing probe today. I could be wrong, can someone point me to a yt vid?
Also, that medal looks like it may be made out of tin, in which case the grey stuff is tin pest. You need to treat that or it will keep spreading, if that's what it is!
Considering the Earth is moving around the sun and rotating. I wonder if Hershel was using that coin to locate himself within the Galaxy, to know which way he was looking on any given night.
Keith that was an absolutely stellar pun.
stop it
Should I not encourage him?
I laughed more than I should have on this :)))
Came to the comments to say just that! You beat me to it!
0:53 "So Germans do have a sense of humor." LOL, well done Keith!
Weird. As the name in German does not sound as that which makes infantile British and US-Americans giggle.
6:12 Damn Keith, dropping dem spicy puns left and right.
DeadLink 404 he's just jealous that Keith could out pun him with one arm tied across his back.
fatsamcastle or with both tied behind his back and reading old crazy handwriting.
He always delivers
Keith is absolutely savage in this one.
"The value is astronomical" 😁
My first reaction: Prof Merrifield has legs!!
Legs like herschel...
...Herschel Walker
William Herschel was also quite a good composer. He wrote 24 symphonies.
6:10 Keith's value is astronomical

maybe not obvious, but at least a start. One hypothesis. A darn sight better than simply saying "stars must be gods" or something.
You could do hours of these topics that involve early science with special guest and I would be hooked like a lion on it's prey.
Thanks!
That was great. Professor Merrifield was really excited about the objects. Would love to see him in Objectivity again!
One of my favourite Objectivity videos so far.

those drawings of nebulae are so beautiful 😍
I love this series. So positive and informative.
Keiths voice is so calm and relaxing to listen to. I could just listen to him talk about anything
Wow, that medal was beautiful.
I wonder what happened to it. Could it have been in a fire? Did it suffer corrosion? Exposed to acid, maybe in an attempt to clean it? Or a galvanic reaction with another metal, perhaps its little box?
Some times I wished I lived in the past just so that my traditional art training in pencils can actually help science.
A drawing is not like a photo; drawings of all kinds of science can be wonderful teaching aids. Have a look at dadrummond on Instagram.

Keep bringing in guests from your other channels! These are always the best ones!
"I would say the value is... astronomical" (trollface) - Keith
@ 6:10 Brady walked right into that one. Keith is a riot!
This is so cool. This is the actual discovery of the flatness of the Milky Way!
Absolutely fantastic, Prof. Merrifield is my absolute favourite from Sixty Symbols and Deep Sky, a real treat to have him and Keith together :-)
That little medal is truly extraordinary!
Wow, 99 videos in nearly 2 years. I remember the first one as if it was... well... about 2 years ago.
I bet they never thought they'd still be going 2 years later.
Still here!
"The value is astronomical." I don't always fall for your jokes, but that one got me. It got me goood. :3
This is my favorite channel in all of TH-cam. Thanks to James and Brady for making it.
Oh, and more Mike Merrifield please.
gotta love mike
Great episode. Even better puns.
i like how the stuff on your different channels all comes together so nicely here

This works really well, objectivity with a prof. keep m coming Brady!
Bring all the profs to the society and show stuff about their subject(s)!
6:10 I can't believe how much I laughed to that pun X'D
This is the most interesting episode so far! Keep up the good work guys.
Brady, do not forget to introduce Keith. He deserves it
These people are simply amazing! I loved too much the way each one of them gives his personal contribution to the spread of knowledge, you guys make many people feel the passion for science.
Love, keep up the good work!
"via lattea" it's still the name of the milky way in italian :)
Best episode of Objectivity. Good job Brady!
Are there any high-res images of that medal? It would be amazing to create a 3D model and 3d-print it in silver or any other precious metal.
How fantastic. He was probably the first human to observe some of these things. What an exciting thing to do.
Which field could you go in today to do stuff like this. Just looking up at the stars and charting stuff, being the first to, like 20 times every night.
It feels like nowadays you'd have to have several degrees and spend years scouring just to go "yeah, that tiiiiny speck, the 77.552nd on the left? That's mine" or "I redefined the orbit of exoplanet HD 55486 j to 8 digits instead of just 7".

Congrats with the 100k!!! Lovely episode with these pictures drawn by Herschel.
I love the integral edge covers used in these books. I assume they are to protect the edges of the pages from dust and moisture?
I always kinda hate astronomy and biology in the same manner as I hate painting and stuff, the better the equipment available to you the more you can achieve with it in these fields.
That's why math and literature are so much more appealing to me. (But even I gotta admit, sitting and observing the galaxy's stars and figuring out their relative positions sounds fascinating)
Particularly enjoyed this episode. Great work guys!
Great episode Dr.Brady!
Ha! Keith was on point with the jokes in this episode!
I just want to hang out with these guys, maybe bring professor Moriarty along as well...and a couple pints. Thank you Brady!
Would love to know if anything more has been learn about the medal you showed at the end!
The stress I feel now in 2020+2021 seeing everyone here in these videos stand so close together without facemasks.
That was amazing.
Extremely cool episode. Thanks much for this.
please keep reviewing historical/scientific discoveries with scientists from the current day. so interesting to watch, i watched in twice in a row. :)
@1:29 nebulo[ic]ty
"So Germans do have a sense of humor" Gold 😂
Great stuff this time guys, really enjoyed this one. Thanks as always
fantastic.
This is irresistibly intriguing 🧐
Someone needs to sell those drawings like on napkins or something like that.
Honestly, this is pretty genius.
I love it how the scientific enthusiasm and astronomy knowledge of Merrifield complements Keith's passion for these objects. Perfect match.
EDIT Man, Merrifield had me laughing when deducing that card image to Messier 64!
This channel is teaching me about everything, even jokes XD

Great channel, btw!
well done! really interesting
My favorite subject is astronomy so I really loved this video :-)
Great work as always. Any clues to the topic of the century episode?
This is what can be done without light pollution. Amazing!
omg this is so exciting! I WANNA BE HERE SOME DAY! Beautful stuff. Makes me emotional thinking this stuff was made by the Herschels!!! THE HERSCHELS!
Keith: "Astronomical."
Keith is the real treasure.
this is amazing thank you for this!
"The value is astronomical"

I think you should check his pockets before you let him out the door. :D Thanks for sharing.
episode 99 at 99k subscribers
Talk about the stars aligning.
I'll show myself out.
xzastd LOL, Just like stars, these won't stay aligned for long!
@@davesextraneousinformation9807 Stars don't really align though (it's just us moving to a different viewpoint
lol no way.. LOVE the guest... go sixty symbols!
That is a Chinese luni-solar calendar, on the reverse is just a map of the solar system. Perhaps related to his attempt to fix the Gregorian calendar.
Yoo-ranuss? Oh come on now Keith, don't be coy.
Of all the pictures of M94 you used the GALEX one taken in UV, rather than visible.
Was it a different Hershel who discovered infrared light? Or ultraviolet I forget
No it was William Herschel that discovered Infrared light. Although I do occasionally get him and his son mixed up.
I like the the then and now images of galaxies etc. amazing the advances in technology which sadly has not extended to the imagery we get from the mars landing probe today. I could be wrong, can someone point me to a yt vid?
so close to 100k
When episode 100 comes out it'll be great if we could also get 100k subs
This was so fascinating 😃 really scratched a brain itch glasses🤓😂😂
Thanks for watching.

@0:58 I saw that...
Boy, I'm excited for Objectivity #100 / 100k Special. What do you fine folks have in store for us?
episode 100 at 100,000 subs?
Do you have something special for #100?
If figures that on the medallion Uranus is labeled as "Herschel".
Two years later, and no answer on the medal. Antiques Roadshow?
