Women have a small chance of being born Tetrachromatic, being born with four color cones in their eyes instead of the usual three. It's believed that about 14% of women have Tetrachromacy allowing them to see, supposedly, up to 100x the amount of colors Trichromatic mammals can. People with eye damage to the lens or those who undergo bad laser eye surgery can become semi-tetrachrome since the human lens normally blocks a lot of blue-violet light that allows the reception of ultra-violet light. There people typically have to wear sunglasses outside all the time due to having a strong sensitivity to light.

Humans typically have Red, Green, and Blue color cones. I wish I could find out what Tetras supposedly have but there seems to be limited knowledge about the whole thing.

Yellow. I bet.

Most likely or something lower or higher like whatever color infrared or ultra violet actually are. Or maybe a white color cone or something but that's just my efficiency autism being :optimistic:

Probably higher cause blue strain a nigga.
 
This one isn't so much a fun fact but something I just found out

Mel Gibson's Apocalypto has been out of print for like 5 years in the states and copies of the film are fucking expensive.

DVD version goes for $30 ish at best and the bluray goes for around $70

And the film isn't on digital either.

Luckily I bought the film around 2008 so I can still watch it.
 
The males of giant Australian cuttlefish have an interesting quirk. Normally, big, burly males hold dominance over the females in mating season, guarding them under their own bodies. However, small males have a sneaky tactic. They perfectly imitate the behavior and skin patterns of the females and manage to slip through and mate with them right under the big males who are none the wiser.

In other words, tentacle hentai traps exist in real life.
 
Experiments done by Benjamin Libet showed that our brain starts sensing signals for movement before we've made the conscious decision to make that movement. Essentially, your choices can be predicted by examining your brain activity. There's a lot of debate over what this means for the concept of free will.

This point was brilliantly discussed in the sci-fi novel called Blindsight. In it, certain characters debate whether human consciousness is a detriment to our brains' functioning and the overall species evolution. It takes a long time for us to make a conscious decision or analysis of something, but the brain is extremely efficient without our "self" input. If you touch something hot, "you" don't even begin to realize it before your brain makes its own decision to move your hand away. One character argues that human consciousness is a drawback, as our brain is perfectly capable of acting without our internal thoughts or decision-making processes. It's a really neat idea to explore, and the book does that amazingly well.

Since I'm gushing about the novel anyway, another concept described there is a thing I'm sure everyone here is aware of, but it's pretty neat nonetheless – the existence of our vision's "blind spots", certain parts of the field of view that the brain has to fill in with information from the other eye or just by splicing seen surroundings due to the lack of light receptors. You can clearly see your blind spot by observing the picture below. In the book, there is a certain alien species that can adapt to a human's blind spots and eye movements in order to stay completely out of sight. Of course, when such an alien encounters multiple people or cameras, this disguise doesn't work. These aliens are also not self-aware, which makes their problem-solving capabilities extremely efficient and makes for a cool illustration of the above-mentioned "consciousness as a flaw" concept.

In ancient Greece in the city of Rhodes, there was an effort to create a crude beam of death by assembling an enormous mass of brass mirrors polished to a shine that would reflect an enormous beam of sunlight onto invading ships in order to burn them. Unfortunately, in practise the beam could at best burn the sails of the ships and not the actual ship.

That's a solar furnace, they're still made today and I think there exists funeral parlors using them for cremation. The amount of energy they can focus is pretty rad.

For those interested in the power of a solar furnace this video, Four Solaire de Mont-Louis, is short and shows the good stuffs including how fucking dangerous it is. It's a research station I guess.

Embedded for those that actual watches videos like that.

The real problem with using on of those for war(or other things) should be obvious.
 
When the greeks discovered that the square root of the number 1 was an irrational number they celebrated it sacrificing 100 oxes.
 
One common thing all rich roman dwellings had was a room called "Vomitorium". This room had a very particular use during parties and orgies, where the attendees would stuff themselves with all sorts of food and drink. After eating their fill, they would go to this room to introduce a goose feather in their throats to puke out all they ate and go back to eat once more.

And since i am talking about ancient Rome, there were nearly 15 different types of prostitues in the roman empire split by where they practised prostitution and prices. One of these was named the "Lupae" who were women that practised prostitution solely for the pleasure of sex and therefore their usual price was a loaf of bread.

I've heard the vomitorium thing before but was it ever actually proven? It sounds like something a dumb historian would write or a Rome-hating country would make up. I know that a lot of the wackier stuff you hear about Roman times is made up or exaggerated.

Hippopotamuses are actually not fat and are mostly made of muscle, about 3,300 lbs of it. They're so dense that they can't float or swim and actually walk underwater. Many watering holes in Africa have 'hippo highways', patted down paths of underwater vegetation from where hippos travel. They can run around 5 miles underwater and they lunge to surface quickly. They have a bite strength of around 2,200 psi, compared to a grown adult male human at around 250. They are also notoriously aggressive, most likely due to being African but it's speculated that it's because they suffer from constant toothaches.

EDIT: Also forgot to mention 'muck spreading'. That's when a hippo takes a shit. Rather than allowing the shit to drop from its anus, it presses its tail against its ass crack, waving it back and forth, shredding the shit all over the place! They can fling their feces up to 10 meters or even sometimes farther. It's for marking territory and pleasing their sick shit fetish.

Male elephants undergo a phenomenon called musth, where their testosterone levels skyrocket and secretions stream down the sides of their heads. This causes even the most gentle individual to go unimaginably berserk, attacking other elephants, humans, even unrelated animals that just happen to be in their way. Most videos you see of domestic elephants suddenly going crazy during festivals and in zoos are a result of musth.
