Lovely video. Louisiane was clearly having the best time, and those online archived sound amazing too!

Starting a letter with an exclamation point is very bold. I love it!

10:21 I create cyanotypes, so seeing Herschel's first cyanotypes was a genuine thrill. We're looking at images he created in 1842 - just three years after Daguerre announced the daguerreotype process in Paris. Herschel coined the word "photography" as well as "positive" and "negative" in reference to it. Photographic images made using organic substances are called anthotypes. The process was invented by an acquaintance of Herschel's, Mary Somerville. Best wishes from Vermont 🍁

The 'Science in the making' project is outstanding, huge thanks for everyone involved. This episode is also fascinating by itself, as the norm for Objectivity.

Simply awesome! Just handed in my PhD thesis and an this video drops … as if the day could not get any better 🎉

This "Making Science" project is wonderful. This is what the internet was built for: spreading knowledge to everyone, not just people who have a friend who has a friend who happens to be the vice president of the royal society or the head archivist of the royal society etc. Also the art museums releasing 3d models that people can print at home. This is the way.

@flamencoprof Год назад

Re those "undeveloped" images: the people who do conservation and/or restoration of famous artworks worth millions have developed/adopted some very non-destructive test methods for detecting hidden images. They are highly motivated due to avoidance of "Oops, sorry, painting is no more".

@pattheplanter Год назад

"Chameleon mineral" (French: caméléon minéral) was potassium manganate which changes colours between green, purple and brown. It appears to have been used as a mordant.

As much as we all love Keith, your videos with Louisiane are great! She is so pleasant to listen to. Also, we would love to see more videos delving into the alchemical notes of other famous scientists. Thank you!

The Royal Society actually shows up in the 2019 version of cats. During the Bustofer Jones scene you can see the painting of Isaac Newton and the outside of the building strongly resembles the society's current location, which is also not far from the other exterior locations identified in the movie such as Piccadilly circus

"Always the horsepiss" t-shirts and mugs coming soon.

@drskelebone Год назад

Is that pink safe? I guess: have they taken some of the pink silk and analyzed it to see what the dye composition/remnants are? With the note that arsenic was one of the colorants, and the general "safety-free" environment at the time, I'm not sure I'd want to handle it without the White Gloves of Destiny.

@tnmoe- Год назад

I wonder if there is some strange connection with the symbol for "urine" being the same as the symbol for "Dry, Low heat" hahaha

@RFC-3514 Год назад

They should definitely look into extracting information from the undeveloped "photo" (which should be perfectly possible with current technology). Otherwise what are they keeping it for? "This might be something, it might not be, and we're not even going to try to find out." Archivism isn't just hoarding.

@pattheplanter Год назад

There is also plenty of the pink silk that they could test, mostly non-destructively. It may be an unknown and ecologically superior dyeing technique.

@MisterTingles Год назад

Once again, great episode! So glad I found this channel, and it keeps delivering outstanding content that tickles my brain in such a satisfying way. also, "Priestly, of Oxygen fame" is a feckin baller ass business card...

@drskelebone Год назад

The internet is slowly reviving the concept of the Latin cognomen to indicate a genre/source/fandom for characters with names that might be mistaken (or not). So you get things like Goku Dragonball, Toad Mario, Mario Mario, Willow Buffy, etc. Priestly Oxygen is just the same idea. Joseph Priestly Oxygen seems perfect to me.

Brady, you should take these recipes and make them on periodic videos. And I'm not just saying it to make you distil some horsepiss, I swear.

i think it's Horspiſs, but yes. this is a good idea.

@Iwoodlikethat Год назад

I was thinking they should do one about the time that the world switched from black and white to colour

@DavidBeddard Год назад

Should it include the alchemical symbol too?

@blindbrick Год назад

10:27 Could the picture become visible when you look at it outside the visible spectrum? In UV or IR, nobody needs to touch the paper.

@_D_P_ Год назад

I was going to suggest the same.

What kids these days forgot is, that before the Invention of Colour everything was just "grayscale" and black and white. 🙃

Yea, I'm happy my ancestors decided to update their eyes with the chromatic update that followed soon after the invention.

@TheStockwell Год назад

I highly recommend you watch the BBC's three-part "History of the World in Three Colours" with Prof. James Fox. Best wishes from Vermont 🍁

@ZaximusRex Год назад

Hey Brady and crew. When you are involved with the Royal Society I would love if you could find something to highlight some of the more esoteric interests of some of the great minds of the past. I've heard that Newton and others had passing interests in Alchemy for example. It would be fascinating if the Society had anything to document this stuff. Thanks!

@noproblem4260 Год назад

Hi guys, why is the date heading such a different caligraphy from the body of the letter? which is outstanding!!!

@realdamageboy Год назад

Why not try to look at undeveloped picture with infra red microscope ?

@CorwynGC Год назад

Why do you think that would help?

@realdamageboy Год назад

@@CorwynGC because infrared wavelength is so powerful, it can go thru paper pages, and if there is some image, the structure of paper will be different. I think with right brightness and right photo exposure we can see the actual image not destroying it

@CorwynGC Год назад

@@realdamageboy except that you have that wrong infrared is less energetic than any visible wavelength. And going through the paper doesn't help in determining the latent image.

Is she Scottish? 3:26 And who had the idea to use urine when making colors? 7:01 That's why (in the US, at least) 2nd Lieutenants have gold bars, but 1st Lieutenants have silver bars.

You spelled "colour" wrong along with "harbour". See... even the error correction wants to change your spelling.

I can't tell if you are serious or not...my not-so-serious answer is to change your language settings to British English, then your keyboard will recognize the correct spelling of these words!🎉
