Post something new you learn today!

Today I learned that a geostationary orbit on mars is called an Aerostationary orbit. Makes me wonder if we have a word describe such orbit for each body, or if we have a general words for others. Guess I will learn one day.

Today I learned Jar Jar Binks is a martial arts master and an evil Sith pawn that worked behind the scenes to undermine Anakin Skywalkers loyalty to the Jedi, and thus help create the Galactic Empire.

That no matter what i do, i am still wrong.

[Dman979]

I learned that creating the rear flap on the Space Shuttle Orbiter in CAD software takes more time than it needs to. I also learned that the first Shuttle launch didn't have said flap working correctly.

[HoloYolo]

I learned in History that the Pilgrims intended to settle in North Virginia. lol

That Sheldon Cooper's (Big Bang Theory, duh!) "Physics!" introduction when he tries to teach Penny some physics is mimicking the introduction of The Doctor (Doctor Who, duh!) to a school class from (second season, episode two/three?).

Wow.... I did not know that. But can you be more specific? Which Dr??? Old season 2 or new series, season 2?

Today I learn the names of the orbits related to other planets in our solar system and several others:

https://en.wikipedia.org/wiki/List_of_orbits

Cronocentric orbit, cytheriocentric orbit, hermocentric orbit....all these fancy names of deities....

What about orbits on exo planets? what do we call them?

[pTrevTrevs]

Well, this isn't really something I learned, but I finished reading Das Boot today. The ending was... Unexpected... Very anticlimactic, probably gave me PTSD.

I... I just don't know what to think about it. They went through so much... and then... The ending... *sobs*

[KerbMav]

Wow.... I did not know that. But can you be more specific? Which Dr??? Old season 2 or new series, season 2?

Hmmm ... tried finding the TBBT episode too, but only got this from DW.

I was sure the scene in TBBT was similar ... did I mix something up?

[Legendary Emu]

Skip trajectories! I don't really know how they work, but they are pretty cool!

[Dispatcher]

I learned that "a bird in the hand gathers no moss".

Although learning about it doesn't mean I understand it....

[EuSouONumero345]

Today I learned that Squad's evil.

[Hcube]

Today i learned that the big majority of the genes of male differenciation are located on the X chromosome, even though it's having the Y that makes you male (!).
Surprising isn't it ?

[justidutch]

I don't find it too surprising, since the X is the chromosome that both sexes share. (I think? It's been a long long time since high school biology)

[Hcube]

[quote name='justidutch']I don't find it too surprising, since the X is the chromosome that both sexes share. (I think? It's been a long long time since high school biology)[/QUOTE]

Yes it is, but still, since Y is exclusively on males, you would "logically" think it has most male development genes, and the X would have female genes only, inactivated if Y was present.

But that's not how it works :)



Today i learned how Insulin is industrially made for treating diabetes, and it's pretty amazing. Cute lil' prokaryotes.

[justidutch]

Today I learned that there is such thing as a Moho boundary!

Quote

is the boundarybetween the Earth's crust and the mantle. Named after the pioneering Croatian seismologist Andrija Mohorovičić, the Moho separates both the oceanic crust and continental crust from underlying mantle. The Moho lies almost entirely within the lithosphere; only beneath mid-ocean ridges does it define the lithosphere–asthenosphere boundary.
