please listen to i am in eskew i am begging you

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.

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.

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.

it turns out the uploader is in fact the woman in the photo (she's uploaded a few other pictures of herself to other articles) and she ran an extremely web 1.0 site on the topic of bondage

this was apparently a long-standing fantasy of hers and she in fact did an entire video plus accompanying photoshoot about it, which was run in a bondage magazine in the 90s and did in fact take place on an abandoned train track. they committed to the bit hard enough that there's even a shot of the sinister villain looming over her with a big document labeled DEED and a pen

the best part is that according to this page, there were two "villains" involved (the woman's two partners, apparently), and the other one was dressed as a gorilla. sadly there are no images of the gorilla kidnapper because that sounds like. even funnier.

No-kill shelters TURN AWAY animals. When they’re full - and they often are because most of these no-kill shelters are small - they stop taking them in. While they are “taking their time to find the right homes for every single animal”, many other animals never get in the door. Somehow they don’t count those animals, or track what happens to them. A success for them doesn’t include the ones they turned away. They’re taking their time because they can. 

The No-Kills who brag about 100% adoption rates are the worst, because they tend to reject the most. The animals who will be difficult to adopt out? They just don’t take those. Special needs? Too old? If they’re going to be hard to adopt out, they can claim to be full, even if they’re not. 

They are telling owners they absolutely cannot take their fifteen year old cat because they are full of litters of kittens. Adorable kittens that will turn over quickly, and boost their adoption numbers. So what happens to the fifteen year old cat? After days of being rejected at the shelters they get dumped on the side of the road somewhere, or worse. 

You cannot imagine the VOLUME of animals that a city shelter deals with. The kill shelters are not allowed to turn anyone away. The difficult cases, the special needs, the elderly, the feral. The dog that bites, the cat that pees everywhere. Every animal is going to be taken in and treated with kindness. They are going to be assessed and treated for their fleas and conditions and behavioral problems. They will get their time on the adoption floor. They will get the best chance possible to find a new home. And if it’s not possible, they will be humanely euthanized, and that cage space will go to the next animal who is already waiting for it. It never stops. While you were working on the paperwork to adopt out 1 cat, three people brought in 4 more. It’s a numbers game that you cannot win if you aren’t turning people away.

A lot of times kill shelters get the animals that the no-kill shelters refused to take. Maybe their owners bring them. Or maybe they got literally thrown in the garbage, abandoned, or put in a bag and tossed in the river, when the no-kill shelter said they were full. The police and rescuers will bring these poor injured animals to the city shelter where they will be cared for. The volunteers will spend days and weeks trying to wash the tar out of their fur, or treat their broken bones, or whatever other horrible thing has happened to them. They will feed and house them. They will put most of them in new homes. They will save many many more animals, by orders of magnitude, than a no-kill shelter ever will. A no-kill shelter will brag about dozens or maybe hundreds of  adoptions. Kill shelters are dealing in thousands of successful adoptions, and they still have to euthanize because it just isn’t enough. There are just so many animals to take in.

The difference between a “kill” and “no-kill” shelter is so misunderstood and prompts me to write a 7 tweet rant on why you need to know the difference and give equal support to both

Municipal shelters are more often tagged as “kill shelters” because they are contractually obligated to serve the community they reside in. If Cleveland City Kennel, Lorain County Kennel, and others alike get a call for an animal they HAVE to bring it in regardless of their

current volume of dogs. So if they have 20 kennels and all are full they must bring it in regardless. Contrasting, private shelters (more often “no kill” shelters) have the ability to pick and choose when and what to accept into their shelter. They do not have to exceed their

max amount of animals. So going back, people often boast that they’d never support a “kill shelter”, never volunteer for one, never adopt from one, never even visit one. And essentially, that’s the problem. Since they are contractually obligated to take in an every animal in their

municipality and they get no adoptions, inadequate staff, no support from the community, no adoptions animals are senselessly euthanized because of the stigma that they are creating themselves. If we all showered municipal shelters with the same love “no kill” private shelters

got, euthanasia wouldn’t even be considered because kennels would open because the community supports them and adopts/fosters/etc. “Kill shelters” aren’t full of monsters who hate animals, they’re typically minimally staffed with volunteers that work so hard to save every single

animal with little to not supports from their community. thanks for coming to my TEDTalk, support your local shelters. All of em :)
