stealing these for tomodachi life lingo honestly
I'm instituting a new policy of "if I can't easily read your crusty scanned PDF then I'm sending it back to you, telling you to get your shit together and save your .docx as .pdf, and causing snakes to manifest inside your house"
this but also if you are in accounting and you have an Excel file please do not save it as a PDF or take a screenshot of it and then paste it into another Excel file
I take it back whatever you have going on is way worse than what I was dealing with holy shit
@thesummoningdark hello?????
yeah no this is a real thing an actual human being said to me
Good afternoon to everyone in the notes having a horrible time! Y'all are fighting demons I never knew existed!! I think every person that makes you do stupid time wasting shit like this because they refuse to learn basic computer literacy should be fired!!
Roscoe ♥️♥️♥️

What's he saying?
remember when i had tiktok and the most noteworthy thing i did with it was pretend with all i had that i didnt know and had never heard of any anime other than baccano
"Every day is a bad day to be a Baccano fan" truuuuue
this is probably my favorite tiktok of all time and I finally got around to showing it to my dad the other day and now he comes home every day and tells me about all the places he saw crumbling concrete and says "guess they didn't add enough chinchilla flakes"
A 50-kilogram anvil floats perfectly on the surface of mercury, because the density of the steel from which it is made is almost half the density of mercury.
damn that shit is light lmfao
Fun fact! Many lighthouses with especially large fresnel lenses would have huge fucking tubs of liquid mercury in the lantern room because it’s a super easy way to make these giant lenses rotate quickly!
Shockingly, however, spending most of your time in close proximity to 500 pounds of liquid mercury is Not Great For One’s Health and tons of lighthouse keepers started to go crazy from the whole. Mercury poisoning thing. Hence why there are a lot of “haunted” lighthouses or wickies that lose it and maybe do a bit of manslaughter.
Anyway, people saw a bunch of lighthouse keepers go crazy and get sick and got empirical evidence that it was in fact related to the 500 pound mercury bath they have to visit every day and then they decided nah it’s fine actually. So we’ve kept the liquid mercury thing and I think that’s beautiful
I love how it is so dense it does not "wet" the anvil, the drops all run and leave with nothing behind them unlike water, oil, sauce... it's super satisfying it's like in cartoons
In a letter written on April 19, 1825, Augustin Fresnel proposed the use of mercury to reduce the friction in revolving lenses. His statement follows: “I propose to float our rotating devices, of the first order, in a bath of mercury, instead of placing them on rollers. This project won't present many difficulties; nevertheless, as I have not put it into execution, I won't require you to adopt it for your first lighthouse.”
Fresnel’s plan for mercury flotation was not put into practice until 1890 when Monsieur Leon Bourdelles, Chief Engineer of the French Lighthouse Service, designed and built a workable mercury flotation system. The mercury bath allowed the lens to operate in an almost frictionless environment and, additionally, allowed the speed of rotation to be dramatically increased.

Ah to be a sailor in 1890 who has to turn to his fellow men and ask "is it just me or are the lighthouses flashing faster?"
They had been slowly getting faster for decades.
It mattered for optics reasons.
Under less-than-ideal conditions, you can only see the beam when it’s pointed more or less directly at you. In-between beams you would not be able to see anything. One solution to this was to create multiple beams, and the lenses Mr Fresnel designed usually created 8 beams. But, even still, duration between flashes could be as long as one minute in the old mechanical roller systems.
The nearly frictionless operation of the Mercury suspension system allowed the lenses (large pieces of precisely ground glass weighing several hundred pounds in some cases) to rotate fast enough that they could be redesigned to create fewer (usually 3) beams. Fewer beams from a similar light source will be proportionally brighter, and the gains in speed were sufficient that duration between flashes could still be reduced to as little as 10 seconds.
This was a big upgrade. It didn’t just make the lighthouse signal faster, it allowed them to completely overhaul the lens and derive more visibility from a light source.
What’s a little Madness, in the face of Progress?
mods are asleep, post the fresnel lens
now that’s glitching. that’s what its all about baby
