Post something new you learn today!

My girlfriend made a appointment to, and I kid you not... This is 100% true.

To remove hair via laser.

Apparently people use lasers t make sure that hair doesn't grow back in certain spots. The same stuff that is used by Curiosity to melt rocks. That kids use to annoy pilots. that hunters use for aiming... Can be used for something trivial as removing the hair from your legs.

When she explained it to me I had quite the "What a world we live in" moment.

Usually this is when you realized you are getting old. XD

Today I learn about the origin of Russia:

[Ethanadams]

Today I also learned that psychology and common morales cannot coexist to learn about some serious mental disorders

Well, it wasn't today but it was few days ago so I guess that could count in. I've learned that peanuts are phosphorescent. I knew they're fluorescent as most oily edible things are, but they actually display few seconds of perceptible phosphorescence when excited with blue, violet and ultraviolet-A, possibly even higher frequencies.

The phosphorescent material is inside the protein part of the peanut, not the oil one, and it's one or more aminoacids in the peanut agglutinin.

I just learnt that:

"learnt" appears about once for every three instances of "learned" in the U.K. In the U.S. and Canada, meanwhile, learnt appears only once for approximately every 500 instances of learned, and it’s generally considered colloquial.

I learned that if I continue to pester my wife, she WILL throw whatever is in her hand, at my head... (in this case, a hair clip)

[Kinglet]

There is an irish brand that makes chocolate with cheese and onion crisps in it. Ew.

[Xeldrak]

A parametric surface seems to be a certain kind of Riemannian manifold.

Also the new Magic: The Gathering expansion seems to be fun.

Lemme guess, Ashens?

[RAINCRAFTER]

The Mongols were the largest empire in the world at one point.

[problemecium]

Today I learned what a Herbig-Haro object is: a double jet structure produced by incipient stars as they accrete mass, similar to a galactic polar jet.

[G'th]

Today I learned that Taco Bell is the perfect medium of cheap and quantity in my area when it comes to fast food.

The same $12 can either not fill me up at McDonalds, not give me variety at the local pizza place, or give me a nice pile of varied stuff at Taco Bell.

A Swedish fish can stretch about 2 meters

The Persian Empire was one of the largest civilizations in the world for hundreds of years, but fell in just three years to Alexander the Great.

Today I learned that according to EU regulation (EC) No 1272/2008, AKA "CLP" (Classification, Labelling and Packaging), the method by which all substances have their hazards classified (eg: methane= flammable, cyanide=toxic etc etc.), that Ibuprofen and sewage sludge have the same classification (harmful if swallowed, irritating to skin, eyes and respiratory tract).

[its part of my job, mildly amusing things of this sort come up now and then]

[RainDreamer]

I learn that photons does not experience acceleration, they move at the speed of light as soon as they are formed:

[Ethanadams]

I learned how to get this ༼ 㤠◕_â—• ༽ã¤

[LN400]

I learned that writing trivial papers on filter characteristics is tedious when all 17 pages are repetitions of the previous pages...

[Xannari Ferrows]

I've learned that people think Carriers are the leading and most self-sufficient craft; a fatal mistake.

[Hcube]

I learn too much stuff everyday. (Medschool).

Most stuff is tedious (did you know that a protein that needs to pass inside a mitochondria must go through complexes TOM, TIM23, TIM44 and mt-Hsp-70(ATPase) in that precise order? Or that once the hypoblast multiplies for the second time, the VV1 becomes VV2 ? ..........fascinating)

But some stuff is amazing : i learnt that there is an individual smooth muscle for each hair of our skin to raise them when we are cold !

I also learnt that the target in a X-ray tube is often in a angled/spinning wheel shape so that energy is shared between different parts of it to prevent it from melting because of auto-absorption. Love this stuff

I just learned (well, last night, but close enough) that boats in Minecraft have been reworked in the dev snapshots for version 1.9. The two biggest problems with them (their fragility and the hit box getting out of sync with your location) appear to have been fixed. Before, boats were an exercise in frustration because you would be out in the middle of a lake and they would break when they "collide" with a lilypad that's 30 blocks away. Now they are useful again.

[T-Bouw]

Today I learned the basics of working with the new logistics-system at my work.

(Yes, it was as boring as it sounds.)

[Dman979]

I learned that a good wingman is of more than a little help when dealing with the opposite gender.

[Ethanadams]

i learned not to mess with the microsoft registory on your computer

[adsii1970]

I've learned (or rather have had confirmed) that there are some people that no matter how much you try to help them, they insist on learning things the hard way.
