reflective properties


Miroir de la Mère

Miroir de la Mère was cut from Val Royeaux in 8:49 Blessed. It was the will of the mad Emperor Reville, who demanded a reflecting pool large enough to draw his vain deceased mother back across the Veil. Many shops and vendors were evicted to make room for his folly, and several memorials to the heroes of the first four Blights were simply toppled. The reservoir supports little in the way of life, as the bottom was lined with lead to increase its reflective properties. Reville intended it for divination, using boats as massive planchettes, but work was not finished until the week of his own death. The waters see little use today, save for lazy—or fornication—sojourns by the nobility aboard decorative gondolas.

Here are the gold cocoons of the Mechanitis Polymnia butterfly! According to Reddit, there are no metals in the chrysalis. It’s all organic proteins and polysaccharides, like chitin. During formation, the material forms what’s called a multilayer: a series of very thin ordered layers. The spacing between the layers (a few 10s to 100s of nanometers), and the specific properties of the materials that the layers are made of (index of refraction) determine the reflective properties of the stack (multilayer interference). Broad spectrum metallic reflection is often due to a “chirped” structure, where the layer spacing changes with stack depth. That is, the layer spacing might be thicker at the bottom and become thinner towards the top, for example. This phenomenon is called structural color!

TL;DR: Damn, that is some @sixpenceee​ shit!

Hello, I was wondering if you could please give your estimation of how great an evil is factory farming in our society. Also I ve seen it claimed that a ridiculously low amount of money, less than a dollar, could save an animal one year of suffering on a factory farm if donated to one of Animal Charity Evaluators top recommended charities. I feel this would be a very hard thing to quantify but I would love if this claim is true, could I please have your thoughts on it?

I don t think those numbers are accurate.

To be clear, factory farming is almost certainly really really bad. Some people think that animals don’t have experiences at all, and so torturing them isn’t morally concerning, but in my experience, intense pain doesn’t work that way; getting your limbs hacked off doesn’t only hurt because I have a high IQ and do lots of high-level reflective processing, and in fact while experiencing something like that I don’t think humans are doing any high-level reflective property. I think that animals who have their tails or beaks chopped off for more convenient containment in tiny spaces experience the exact same thing, when that happens, that I would. Same for chickens bred to gain so much weight their legs break under their own mass are suffering, same for animals hacked to death by their fellows in their cages because of desperation and overcrowding. Factory farming is a moral catastrophe. 

But it’d be really surprising if there were a cheap intervention that reliably made people vegetarians. It’s really hard to get people to change their minds and their behavior; advertising spends billions every year influencing peoples’ product choice, and that’s mostly on things which are much easier and less consequential choices than going vegetarian. And the evidence base is very weak. The effective altruism movement has recently funded a lot of studies into various attempts to sway minds on factory farming, which is great, but most of the studies were too small to detect any effect. That could mean there’s no effect and does mean that the effect if it exists is probably pretty small. Until we can fund much bigger studies it’s hard to even put an order-of-magnitude guess on how much it costs to avert a year of torture for an animal on a factory farm.

Animal charities we can be more confident about include ones which are trying to develop meat alternatives (particularly alternative mayo, alternative eggs, and similar products, which aren’t as hard as consumer-ready alternative steaks and have a commercial market as big as or bigger than the direct-to-consumer market.) There, it’s easier to measure how much suffering would be prevented by a change in a specific industry to meat alternatives, and how much donations can push the development of those alternatives through the pipeline faster. Many of the animal-concerned people I know gave to the Good Food Institute last year, which seems like a reasonable way to aim for the measurable. 

If you want to reduce the harm from factory farming without being vegetarian or vegan, consider checking whether a 50% reduction in meat consumption is a significant cost for you, asking for your university/workplace to offer more vegetarian options if applicable, avoiding chickens and eggs (which have particularly awful suffering/pound of meat ratios), and opposing ‘ag-gag’ laws which make it illegal to publish information about the conditions on factory farms and therefore make it harder to create pressure for more humane conditions. 

Fostering the Snow (#1)

Winter is up pretty much around the globe. And in this post, we wish to enumerate on fascinating properties of snow and things you could do when this icy incarnation has engulfed your life.

Snow is colorless and Translucent

Snow, like the ice particles it is made up of is translucent. This means that light does not pass through it easily and is reflected.

This means no wavelength is absorbed or reflected with any consistency, so the white light bounces back as the color white.

Deep snow can often appear blue. This is also the reason why holes dug in snow appear blue on the inside.

Sunburns in winter are a thing

You may or may not have heard that you are most likely to get a sunburn when there is thick snow on the ground and the sun is overhead. 

This is not because that the sun reflected is dangerous, but because of the reflecting property of snow more sunlight is hitting you than usual. 

The sunlight from the sun + sunlight reflected off the snow —> hits you.

So, sunscreen up people , even in the winter!

Methane Bubbles

The strange phenomena occurs on top of lakes and  is caused when permafrost in the area begins to thaw out.

Organic matter stored in the bottom of the lake begins to thaw out, and microbes decompose it, releasing methane. Methane does not dissolve into the water, and instead forms bubbles

Throw boiling water in the air

Also known as the Mpemba effect, this is a consequence of the fact that hot water will cool and freeze faster than a cold one.

( It has also experimentally proven that using boiling water yields faster ice cubes. You can try it at home too! )

Soap Bubble meets snow

The nucleation of the soap bubble when brought in contact with snow / any cold surface is truly breath taking sight.

Have a good day and as always have fun ! :)

A big shout out to lgbtmed for asking the question. Thank you!

Indrid Cold, commonly known as The Grinning Man, is a purported humanoid entity. His name comes from his tendency to smile at those who encounter him.

The Grinning Man is reported to be human-like in appearance, though is commonly associated with UFO activity and is sometimes believed to be an alien. It is also believed possible that he is connected with the Men In Black. In his first sighting, he was described as being over six feet tall and wearing a reflective, green suit with a black belt. He had a dark complexion and small, beady eyes set far apart. He was described as not having any nose, ears, or hair. In his second known encounter, his suit was said to be blue instead of green, but still retained its reflective property.

According to reports made by Woodrow Derenberger, Indrid Cold came from a planet named Lanulo in the Genemedes galaxy, and that there were two other “grinning men” by the names of Demo Hassan and Karl Ardo.

Indrid Cold was first seen on October 16, 1966 when two boys, Martin “Mouse” Munov and James “Jimmy” Yanchitis, in New Jersey were walking on Fourth Street, when they saw a surreal figure standing near a fence. As they walked closer, the figure was a tall bald man wearing a metal green suit who was staring right at them with a huge grin. The idiosyncratic man chased them until they got away from him. UFO sightings were also reported around the area.

On November 2, 1966 in Parkersburg, West Virginia (around the same area and time as the Mothman came about), Woodrow Derenberger was driving his way home on Interstate 77 until he heard a crash. Then, an unidentifiable vehicle appeared to land in front of his truck. He described it as a “an old fashioned kerosene lamp chimney, flaring at both ends, narrowing down to a small neck and then enlarging in a great bulge in the center." The Grinning Man came out of the vehicle with a dark tan, and walked up to Derenberger and telepathically said his name was "Indrid Cold” and he meant no harm. Cold said he just wanted to know more about the human race and he would visit Derenberger again. After the encounter, Derenberger stated that Cold revealed he was from the planet Lanulo in the galaxy of Genemedes.

During the same period in Point Pleasant, West Virginia, the Lilly family had been reporting that poltergeist activity in their home, such as diamond shaped lights. The Lilly’s daughter, Linda, was sleeping one night, and awoke to see a man standing over her.

It is commonly believed that the Grinning Man may be an alien entity, and is supported by its close connection with UFO activity and with Derenberger’s sighting. It is also said by Derenberger that the Grinning Man is in fact a species of aliens with multiple “grinning men”. However, the third sighting by the Lilly family suggests instead that it may be a ghost or spirit of some kind and was connected with poltergeist activity happening in the residence. Others believe that it is a normal human man or a hoax based off of the popularity and fear of the Mothman, who had been first sighted around the same time.
