Links to my free sewing patterns! - big manta ray - smaller manta ray - monster friend (those monsters with horns I’ve been making lately, but without horns) - pie slice - Fred, the Fish of Minimal Effort - tiny cat (aka Jiji) - mini mothman - whale shark/donut whale shark - juggling frog/toad (aka my smallest, simplest frog pattern of the three I’ve made) - large frog - tiny hedgehog - minecraft bee - minecraft zombie - blorbo - Strawberry Hearts quilt pattern - starfish - little octopus - canvas tote (wider than it is tall) - canvas tote (taller than it is wide, more of a grocery bag) - basic bat and ghost - mini mushroom friends - whale - hammerhead shark - simple seal Tutorials: - flannel baby blanket tutorial - onigiri bag tutorial - tomato pattern design walkthrough (how I design the pattern, not a link to the pattern itself)
Free pattern post, now updated with a link to the seal pattern! If it’s been a while since this reblog when you read this, it’s worth clicking through to the original post, I will update it whenever I share a new sewing pattern
seething about the fact that i will never experience photosynthesis in my own useless cells. i bet it feels so good when the light of the sun both warms you and fuels you at the same time. a bone-deep satisfaction mixed with a heated sugar-rush and endless brightness. not that i would fucking know

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.
Lens Rotation by Thomas Tag | United States Lighthouse Society
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
The mercury baths are slowly being replaced by a new system, this video about it is super interesting and explains it way better than I can!

alright I've got to do some quick math to explain attitudes towards AI to my boss.
we're looking to create an AI policy, and when we were talking about this, my boss (older millennial) was genuinely shocked to hear that younger people do not (seem) to view AI positively (a la the recent commencement speakers being booed)
please rb for larger sample size!
Question 1/3
What is your age, and do you feel AI is a net positive or net negative in our lives today?
under 18, AI is a net positive
under 18, AI is a net negative
18-29, AI is a net positive
18-29, AI is a net negative
30-45, AI is a net positive
30-45, AI is a net negative
46-60, AI is a net positive
46-60, AI is a net negative
over 60, AI is a net postive
over 60, AI is a net negative
Question 2/3
How often do you visit or interact with museums/archives (whether in person or online)?
Frequently (multiple times per month)
Often (multiple times per year)
Occasionally (a couple times per year)
Rarely (once every couple of years)
Never :(
Question 3/3
If you saw a museum was using AI in exhibits, marketing, research, etc., would you be more or less inclined to visit that museum?
under 18, more inclined
under 18, less inclined
18-29, more inclined
18-29, less inclined
30-45, more inclined
30-45, less inclined
46-60, more inclined
46-60, less inclined
over 60, more inclined
over 60, less inclined
Thank you for helping with this data collection. Please rb for as big a sample as possible!

I'm going to throw just a little nuance in here, based on that last question.
Generative AI being used to do things like develop exhibits, create marketing materials, etc.: bad. Do not want. I will not go to that museum.
Analytical, specialized AI used for research methods: totally fine with that. It's what AI SHOULD be used for. Counting cancer cells, identifying areas of interest in thousands of satellite photos, organizing mass amounts of data, etc. The sort of tedious mass tasks that are too extensive for humans to do on their own due to sheer volume.
