That the Supreme Court voted to uphold birthright citizenship shouldn’t be exciting or cause for celebration. That was a bare minimum expectation.

What we should all be very concerned about is that it was only upheld 6-3, with Kavanaugh concurring and dissenting in part. That three justices are so comfortable disregarding not just the plain text of the 14th Amendment, but the legislative history that went into crafting it, the constitutional processes for ratifying amendments, and who are eager to see a President wrest unchecked executive and legislative power with full approval from highest court in the land, is not just concerning. It’s a neon-red alarm and a terrifying reminder that one party and one agenda neither believes it needs nor must it answer to the majority of the people it governs.

I do not agree with veganism as a moral standard. If it is your personal moral stance, that is fine. If you think humans eating meat is inherently immoral, I don’t want to deal with you, you’re hopeless. Vegan ideology behaves more like a sect of evangelical Christianity than a dietary choice.

[literallycrashingoutrn]

Veganism is better for the environment, but claiming that it's a morally superior choice ignores cultural and economic factors that make people eat animal products.

[byjove]

It is not inherently better for the environment. That is the thing. When you begin trying to explain that local, sustainably sourced animal protein is better for the environment than imported plant proteins that are farmed 3,500 miles away using slave labor, they start tuning you out. Down is better for the environment than polyester stuffing, leather is better for the environment than pleather. We should work on making animal agricultural practices more sustainable instead of trying to shame everyone into eating plant products that are also farmed unethically and unsustainably.

I wanted to give a head's up about the pillows have been in the making for months. They are almost all ready. More information is better than less with nice things that are a little pricy.

DETAILS: They're 100% cotton, 21 inches, woven tapestry and have a zipper on the back. They will be available unfilled, I want to make them as affordable as I can especially for people overseas. PRICE: They will be $70 + shipping costs.. I'm not someone who can sell hundreds, so the price to make them is higher than a bulk reseller of public domain art pillows ^^; That said, I did have enough made that they should be in my shop for a while so don't worry about missing out. I appreciate everyone who's expressed interest in them.. He's a nettle fairy who lost his hand in a moth trap accident when he was a child. He has a very pampered but anxious service bee-fly named Playboy who helps him with tasks. They're never apart.

"You should create for yourself" and "it's okay to feel discouraged when creating your own original projects if no one interacts with them" are two sentences that should be able to co-exist with each other

[awakefor48hours]

On the one hand, you should kill that capitalist in your head that tells you to make art only for the enjoyment of other people. On the other hand, it's totally fine to be disappointed that you spent hours or even days on something that only got 4 notes. You can feel both ways.

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

[ben-the-hyena]

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?"

[asteroidtroglodyte]

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!

listen to me. this is my final message to you. when you are at your lowest a fictional guy will come to you and when that happens you must start putting them in situations. this is the meaning of life.
