What did you learn today?

The pine ovule before fertilization has a megagametophyte, housing the egg cell. I know this because the egg cell looks like 2 Saitamas. Egg
 
I learned how to factor 2nd and 3rd degree polynomials with like 5 different methods.

And I learned the SOAP method.
 
I learned a lot about plate tectonics and about minerals and rocks. I know it sounds boring but it's actually really interesting because of how easily ONE rock can tell the entire history of earth.
 
I learned that in a couple million of years, California has the potential to become it's own micro continent. DAMN PLATE TECTONICS, YOU SCARY!
 
A couple of things over the course of few weeks. 

1) I learn how to drive. While it's not certainly related academics, I thought it was important enough to leave a mention. I was already driving for about a couple of months, but recently, I have been getting more comfortable of driving without the need of my parents in the car. I'm hoping to get my driver's license before I go back to school in September. 

2) Over the past month or so, I been checking out grammar lessons in order to improve my sentence structure. English is one of the more, difficult task for me, simply because I'm a lazy fuck who always want to get straight to the point as soon as possible. I can write better if I can actually try, but I end up spending too much time on a single sentence -- analyzing to make sure it gets the point across lol. I'm still not finished with it yet, but I learn more things on the differences of past tense, present tense and the like. 

3) I heard more information by studying Ivan the Terrible, along with other rulers thanks to the Epic Rap Battle of History, in order to understand the references they have made. Interesting stuff. Frederick The Great is perhaps the best on in that battle.
 
TIL that people can actually be born and live without spleens, contrary to potentially popular belief.

Asplenia is the result of a harmful genetic mutation in a ribosomal protein gene "SA". We need two functional copies to have a spleen, but just one defective copy results in being born without one entirely. So these people lack an organ that provides adaptive immunity to bloodborne pathogens and can easily die to infection. Vaccinations are the most reliable way for asplenic people to defend themselves against things that wouldn't be too much of a nuisance for normal people. Your spleen will have to be removed if it's been damaged from traumatic injury: kids who previously had a spleen will be as vulnerable to bacterial infection but adults already developed plenty of immunity by the time their spleen is removed in this scenario, save for the occasional vaccine.
 
I learned the cataloging system, the MARC 21, which is one of the most extensive ways (and time-saving) process of cataloging books. At first, it was confusing, since it's like learning a brand new language, but after a while, I managed to get the concepts.
