Your teacher, mom, and virtually any adult with a thoughtful mind would never approve of Twitter as a learning tool. And how would they with this whole infinite source of the not-very-serious side of the internet where memes, jokes, and burns are roaming free?

But people are proving them wrong by sharing incredible facts brought to them by Twitter that should have been put in the textbooks. From realizing the symbol “&” is a ligature for the word "et" to finding out that an 18-inch pizza has more of a good thing than two 12-inch pizzas, these are some of the facts that could have been part of my wisdom bank this whole time.

So scroll down, upvote your faves, and after you’re done with this post, check out our previous list of 30 random facts that will make you feel "today years old."

Look, I am not saying we should believe all that Twitter has to offer. But it turns out, the things we were taught at school are not so innocent either. Some facts we still believe to this day are complete myths, and they had better be laid out bare before you become "today years old" to realize they aren’t true.

You probably would place a pretty high bid on the fact that Columbus discovered America. You’re not the only one. A 2005 survey showed that 85% of Americans believed Columbus discovered the continents and only 2% correctly answered that he couldn’t have discovered America because it was already inhabited by Native Americans.

The London Underground maintain several stations that trains never use. They are reserved for TV and movie locations so as not to close down functioning stations

In DC we use drab brown colors, keeps the lights dim and make every station look similar just to remind everyone they are going to work to a job they hate.

That's kind of adorable. They do that with the school buses at the preschool where I sub sometimes because the kids have an easier time remembering what animal they are than what their bus number is.

They do this as well on the London Underground - even the colour of the poles in the tubes match the line colours on the maps and in the stations. Nice to see how many cities actually did think it through pretty well.

In Montreal (Canada) every subway station is completely different. You can have one in red tile, the other one electric blue. Even the benches are different!

In Brussels different artists have done each. Well, I was there years ago, but it was that way then. One had the same scene painted as a huge mural, with the four seasons affecting it. Just beautiful. I didn't even mind waiting for the train.

In Stockholm every station looks different and wonderful and covered with art! It's "the worlds longest art exhibition" (google it). It's so much easier to see where you are when stations don't look the same. I'm always lost in Washington because if you can't see the sign you don't know where you are.

Same goes for Prague. Each metro line is a different letter and colour and tiles on the walls are matching accordingly

Mexico City does this also with their metro. Every line is a certain color, and every station has a symbol in the color of the line it's on. Some Mexicans are illiterate, while others don't have Spanish as a language.

In Barcelona each line has a colour as well for tiles and also as a name. They have a number, too, but everybody know them by their colour. So when we are in another city, we still call the lines by their colour and look like illetrates to locals! :S

In NYC none of our tube stations match so our tourists don't know where they're going, but the gang bangers wear their own colours so they're at the correct stations. It's so our muggers don't get lost!

Hello, many fully literate travelers still need the colors and symbols to help keep it all straight. Have you ever tried to navigate metro systems in a dozen different countries? Did you learn all those languages and alphabets? I didn't think so.

Another fact which turns out to be a myth is the tongue map idea, which suggests that different parts of our tongues identify different kinds of tastes. However, the University of Florida Center for Smell and Taste stated that “the locations of those taste buds aren't in accordance with the 'tongue map.'” And even if taste buds are indeed receptive to certain types of tastes, the difference in reality is tiny.

You've probably heard how Einstein failed math in school and was not an A student in general. It turns out, the only exam he failed was an entrance test to the Zurich Polytechnic he had to take in French, which he didn’t speak well at the time.

Read a funny story about him. He used to pay meals with checks. People didn't cash them cause Dali's signature was more worthy than the pay, so he got many free meals doing so. Not sure if its true, but like this story.
