It looks like one of the angled brackets on the second prism is turned so it's no longer secure to the base. It's visible on the left side of the screen at 2:06
Goosebumps on a youtube astro hunt on friday evening. I have been in search of Fraunhofer's spectroscope, wondering how it would look, what it was made of. This episode shows spectroscope parts he probably made himself. You cannot understate the importance of his invention. I hope to see it with my own eyes some day.
I've been following this channel ever since it was first created. I always enjoy seeing original instruments, manuscripts, and original material on which the experiments were performed, as well as some of the behind the scenes activity that went on at the time. Keep up the good work.
Ah, what an improvement to an otherwise poor morning. These objectivity videos always make me appreciate the early scientific work and how much was accomplished with the resources they had. Also, of course, listening to Keith is a real delight.
At first I thought this was an inconsistency, but now I think it had to do with timing. Around 8:30 you discuss that Fraunhofer didn't know that the lines correlated to elements. But around 7:25 , Somerville, writing of something that happened before Fraunhofer's work, said that the lines proved that the same substances are present in the earth and the sun and stars. However, she wrote that book (I looked it up) when she was much older. So, did she not know what the lines meant when she first saw them, but decades later, when she wrote about seeing them, her commentary included knowledge gained in the interim?
Love the new watch! Your Explorer is a beauty, but there's something timeless about the Speedmaster Moonwatch! The Explorer is a true tool watch, whereas the Omega is an instrument unto itself. Truly appropriate for the Objectivity theme! Bravo.
I'm honestly amazed by how precise everything is in old instruments. They didn't have 3D printers or computer-driven mills and they still managed to make things the average Joe couldn't manufacture in 2023
-standing in front of a window with sunlight beaming in on the single day in England it's visible from the ground and with an ACTUAL original Fraunhofer prism in hand: "I think we've talked about them a lot, now we should see the [Fraunhofer lines] in all their glory!" 😮🌈🤩 ...looks at b&w book drawings and ends video. 😐😑
Did they not, at 6:46, show the refracted light using the prism? To observe the lines within the light would possibly have needed more than Keith and Brady playing at science, but the lines were there, nonetheless.
@@WhatAboutTheBee the 7 Wollaston lines are surprisingly easy to see, particularly the oxygen, sodium, and hydrogen alpha lines. They really only need a white piece of paper or something.
I would like to know Keith's entire journey from school to the Royal Society... If this has already been a video can someone tell me which one please? Great video thanks 🙂
The story of Frauhofer's narrow escape is even more peculiar than indicated. Fraunhofer's master was an old-school glass-maker, and had no use for the sort of new-fangled optical theories. He refused to allow Fraunhofer to pursue an education. When the building Fraunhofer was in collapsed, the rescue effort was led by the Prince-Elector of Bavaria, an official with sort of the same status as a current-day president. The Prince-Elector took an interest in Faunhofer, and put pressure on his master to allow Fraunhofer to get the education he desired.
Excellent Brodie and Keith. Sometime Brodie it would be interesting if you and Keith were to talk about where he sees himself in the long line of RS librarians and what he see's himself as leaving for his successors. I suspect it would be fascinating. Might both of you be interested in doing that?
Another great video. Kind of related, I recently learned a bit about Iceland Spar and how it was used in early optical instruments and apparently there was a constant shortage. Would be interesting if there’s something in the archives about this.
Could there not be a push for posthumous fellowships for women like Mary Somerville. When we are trying to send out a positive message to young women and girls that science can be rewarding and inclusive area to study, this would a good start.
Why do you have to torture me? I have to wait 7.5 hours until school ends to watch this. Why do you do this? Is it because I like Chick Fil A better than KFC?
There are giant Fraunhofer lines which span the universe. They’re called Einstein’s Force Lines. They also represent a spectrum, but all spectrums are sources of meaning, so the government keeps them a secret. People are not supposed to experience meaning, because that leads to orientation, and then the application of free will. It’s kind of funny, but the architect who designed the dormitories at Berkeley University built Einstein’s force lines into the exterior of the buildings. I guess he was was a fan of true meaning.
8:25 So if a thing were to be constructed with or coated with one of these elements, we would not be able to see it, perhaps an air craft of some description ?
Would be cool to try to see the Fraunhofer lines with his original instrument
That would be ridicilously legendary. :D
Fraunhofer was the guy the Fraunhofer Institute named themselves after, who was the group that created the mp3
Yes.
I loved weeing Keith being excited about doing the intro phrase!
I'm way too fascinated by that finely crafted little brass bar that holds the one prism, along its edge, to its fixture.
Yes it's beautiful!

Came here to say the same 😄
Great effort of Brady to capture the cat video audience at 6:55. :)

I clicked here because I saw that it was Brady - never disappointed by anything he produces!!
Yet another marvellous video, thank you very much.
Thanks for tuning in!
It'd be interesting to find out about people who borrowed instruments but never returned them and any excuses that might have been given.
The prism looks amazing.

wonderful example of how science moves from, initially, a new observation of "What", to, maybe much later, an accepted theory of "Why".
YES Objectivity video!
Great video! We had a prism when I was a kid that I was fascinated by! Loved hearing a bit about Mary Somerville-would love to hear more about her.
I love this series. Spot on with history.
Love this channel so much
I see I have to study and appreciate Mary Summerville
My spelling is off but my heart is not.
She rocks!
You rockstars are geniuses.
this channel is such a gem !
You and I are on the same wavelength. This is a _spectacular_ channel. I love examining science through the lens of historical objects.
@@HermanVonPetri it really is!
Brady love all his channel, and I do too, This one is an special one, to have te oportunity from so far away to see this things, thank u Brady
Fantastic Episode! Really enjoyed this one, its so great to hear about these early international collaborations
I love Objectivity.

Hooray! Keith welcomes us today!

Keith has the coolest job ever.

a timeless watch, oxymoronic!
I have a calculator watch

Good introduction Keith!
Brady is back!
Wonderful, wonderful video!

It makes me happy that you pronounce "Fraunhofer" as "Frownhofer" instead of "Frawnhofer" =)
Fascinating once again!
Just fascinating…. Thank you showing us!

Superb once again
So amazing what they could do with the technology back then!
I would love to create the technology to enable new science one day.
Another great video. Kind of related, I recently learned a bit about Iceland Spar and how it was used in early optical instruments and apparently there was a constant shortage. Would be interesting if there’s something in the archives about this.
Id love to see a series like this but with objects at the Smithsonian
The box is marked 48, but the instrument is marked 50. Was the box repurposed? Are 2 instruments missing?
Could there not be a push for posthumous fellowships for women like Mary Somerville. When we are trying to send out a positive message to young women and girls that science can be rewarding and inclusive area to study, this would a good start.
When Keith pulls out the gloves, you know its serious
Looks good mate
I wanted to see the lines!
NEIL IS THE MAN!!!!
I was just about to look up how they used to measure the absorption lines
Mess with the Godfather of science, end up with a Horsehead nebula in your bed.
'Fabulous bust of Mary Summerville.'
I'm sorry, I'm such a child
Wohoo Objectivity
so keith was a guitarist for the rolling stones?🎸😃 and herschel invented the knapsack.
You HAD to mention that using these absorption lines the element helium was discovered on the sun before it was discovered on earth.
So silly that smart men who held a women in high esteem still didn't let her into their club.
Cooties
super early yay! very interesting video!
7:35 is that a Corona Virus painting?
It's weird seeing "the first" calcium H and K lines. O_O
Why do you have to torture me? I have to wait 7.5 hours until school ends to watch this. Why do you do this? Is it because I like Chick Fil A better than KFC?
Cmon Brady! Explain Yourself!
Please send to complaints dept. C/O Unmade Podcast.
sneak a bathroom break 😉
A dark matter of its time.
🤟
Felt too short
Another video
Truly
Couldn’t have put it better myself
Mmmmmm😊

So if a thing were to be constructed with or coated with one of these elements, we would not be able to see it, perhaps an air craft of some description ?
Observe using sun light that is, an artificial light cast on the object would expose it .
