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."

And still today, Natives are being harassed by police for protesting there peacefully. Nothing much has changed..

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

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.

Actually, this is not really a baby skull. Adult teeth start as "buds" or "seeds" and don't get as big as that picture untill you're 6-9 years old... This is a child's skull with pieces of bone removed so you can see the teeth sitting there but not a baby skull!

I also used to have one because I miss the correspondent adult tooth. It's normal since baby teeth fall because the adult ones "eat" their roots.

The terrible thing about this picture is that it's the preserved skull of a child. A child who has died before their time and not been granted the very least we can do - a decent burial..

Fake picture. Nature is wonderful as primary teeth are small enough for a small maxilla and mandíbula. As you age the transformation to permanent dentition grows gradually as buds mature to permanent teeth in a very specific order. And for humans only once. Other animals who worn down their teeth will replace permanent teeth a certain number of times and when last replacement occurs they die.

Nope, this is not a baby skull, baby milk teeth are not these big roots and an adult have not more than a line of teeth with these roots, so, maybe is an alien, a giant or ...

This photo is grossly misleading...it's not a baby's skull. This child was at least 6-7 years old. And babies are not born with all the teeth in their mouth...they have teeth buds for the teeth and the teeth grow from those small buds. Don't believe everything you see on Twitter or BP.

not true.... Adult teeth grow from buds. I am a trained Dental Assistant. The adult teeth push out the baby teeth. And probably this is a reproduction of an adult with superfluous teeth, or just a model of the growth and placement of teeth. Google it. Where is the source of this information?

While I know that’s how it works with the adult teeth, seeing this image is DEEPLY DISTURBING and it wouldn’t surprise me if I have nightmares because of it.

That's not a baby's skull - look at the proportions of it for a start, and the length of the roots. Baby teeth have very shallow roots because they are designed to be lost. It is actually the skull of an adult with hyperdontia, where too many teeth grow.

I would always consider myself to be liberal and not really religious but if that's authentic, that's deeply disturbing. Human remains do not belong on display in somebody's house.

Because we don’t tend to show off infant or children skulls much, nor carve them up to show their interiors even when their skulls are shown.

That was unsettling, a little, first because it was a baby's skull and then the double decker teeth rows.

When I had my wisdom teeth removed in high school, the surgeon also removed "tooth material" embedded in my gums. Now it makes more sense.

That might have been supernumerary (extra) tooth buds that never fully developed (which is even cooler imo because it's really rare). By the time your wisdom teeth erupt, all of the rest of your adult teeth should have already come in. If you still had unerupted adult teeth by high school, then it's likely that the dentist would have let you know some years before then. But then again I don't know what country you were in or how long ago this was so I could be completely wrong about that.

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.
