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.

Lovely video. Louisiane was clearly having the best time, and those online archived sound amazing too!
Simply awesome! Just handed in my PhD thesis and an this video drops … as if the day could not get any better 🎉
congratulations 🎊 What was the area of study?
Congrats!
Congrats!
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.
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.
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!
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".
"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.
Thank you for everything Brady
Louisiane just made the whole subject fascinating and addictive!
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
the Royal Society 'making science' link is a glorious time consumer - thank you!
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.
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.
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.
I would love to see an Objectivity random dip for the Royal Society online archives!
I blame you for the time that's about to be sucked out of my life now ... thanks so much for sharing that link!
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...
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.
Needs a White Gloves of Destiny app to randomly choose objects for us to look at.
Please do more episodes with color as the subject
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 🍁
"Always the horsepiss" t-shirts and mugs coming soon.
That was pretty cool about John Herschel and aurophotography....cynanotypes too.
For April fools next year can we get a t shirt like the objectivity Darwin/Newton handwriting but is says Horfpifh ? 😄
i think it's Horspiſs, but yes. this is a good idea.
I was thinking they should do one about the time that the world switched from black and white to colour
Should it include the alchemical symbol too?
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.
I was going to suggest the same.
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 loved this episode! Louisiane is amazing!
I wonder if there is some strange connection with the symbol for "urine" being the same as the symbol for "Dry, Low heat" hahaha
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!
3:40 I believe it technically reads horse*pish* but, of course, this means the same thing (pish and piss being synonyms).
She's great. More of her.
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.
I could well imagine you could inspect what is hidden in the undeveloped image with Raman spectroscopy
I remember watching a show called "The Worst Jobs in History", hosted by Tony Robinson, and one of the jobs featured was that of a Purple Maker.
I not sure I want to know how the urine was collected from the horses...
Hi guys, why is the date heading such a different caligraphy from the body of the letter? which is outstanding!!!
This video should have been called "Horsepiss and Pinkmail"
That sounds like a Technical Difficulties title.
MYSTERY BISCUITS!!!
With regards to those faded color samples, if the recipes are there, why not try to recreate them?
Great topic 👍
3:40 I thought that was what a Yorkshireman goes into in his final days.
What I see is a stripes, green thin white, thin black, orange, thin black pink, thin black, orange, thin black, thin white, green and thin white.
Robert Hooke -- greatest scientist of all time, and victim of the thief and scoundrel Newton.
❤ Objectivity ❤
Pretty great timing, SciShow Tangents put out a podcast on color today as well.
Keith (off camera): [whispers] Enclosures.
A whole video about colour at the Royal Society, that doesn’t even mention Newton?
the combination of her english and french(?) accents sounds almost dutch to me
Hahahaha, I saw red yellow, yellow, red. I am very colorblind, but I knew that. Nice to see there were people worse off than me lol
3:43 Nobody tell NileRed about this :D
Damn Brady been losing a lot of weight anymore and you might blow away with the wind.
Wherein I learned the chemical usefulness of horsepiss.
Brady looking slim, I hope you are doing well.
Why not try to look at undeveloped picture with infra red microscope ?
Why do you think that would help?
@@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
@@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.
It's well known the world was mostly b/w until the 1950s :P
The Romans used urine in leather making
And laundry.
You really don't want to live near a tannery...
No idea what colour is, still yet to be invented. However this is when color was invented.
Horse piss, huh? I wasn't expecting such... colorful language.
You're looking lean these days Brady
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!🎉
Color*
@@Zuluknob Color*
@@beachboardfan9544 No, but you're going to post it again with sarcasm to this very comment and it'll keep going forever. And it will keep being wrong. And it's exactly what you''ll post again next: "Color*".
@@Zuluknob Well the host is not English, Brady is Australian, but they also spell colour with a u.
@@Daniel_Rodrigues_89 😎
It's a shame they didn't taste anything and discuss flavour too... or talk about their neighbourhood....
I have a challenge for you, Brady!
Make a video of you reading any old recipe for making dye without getting demonetized by the ingredients haha
Louisiane is simply adorable!
I want the Objectivity "Always the Horse Piss" T-shirt.
This was fun. Why did I find this fun!?
Could be the video, but I see
Gray Green
Orange
Pink
Yellow
Brownish Gold
✌
It's cool that you put all that manuscript online, but I need Keith to read it to me.
I would buy that audiobook.
I am colourblind a GF teased me about it, that was the end of an otherwise beautiful relationship.
I do hope she is reading this!
