Science definitely doesn't end at high school, and it's once you take your learning to the next level that things get really interesting. In no particular order, here are some mind-bendingly incredible facts that we didn't learn at high school.  

This Smart Friday post is a continuation of our last post, check the last post here 

7. You CAN see without your glasses

According to MinutePhysics, all you need to do is make a pinhole with your hand, which will help you focus the light coming into your retina. Sure, it won't give you 20/20 vision, but it's a good start if you've left your glasses at home. 

8. This is how a face forms in the womb

Embryonic development is an incredibly complex process that scientists are still just beginning to understand. But one thing researchers have been able to map out is how the embryo folds to create the structures of the human face in the womb. We could watch this all day.

9. Popping your knuckles isn't necessarily bad for you

One researcher popped the knuckles of one hand for 60 years but not the other, and found no discernible difference in the amount of arthritis between the two of them at the end of his experiment.

10. A single solar flare can release the equivalent energy of millions of 100-megaton atomic bombs

 And they're happening all the time.

11. Cats always land on their feet, thanks to physics

As Smarter Every Day demonstrated with this awesome slow-mo footage, cats actually use the two halves of their bodies separately to ensure rapid rotation (don't try this at home).

12. You'd be better off surviving a grenade on land rather than underwater

Those balloons? That's what would happen to your lungs if an explosion went off near you underwater

13. If you spin a ball as you drop it, it flies

I mean, it really flies. It's thanks to the Magnus effect, which occurs when the air on the front side of a spinning object is going the same direction as its spin, which means it gets dragged along with the object and deflected back.

Meanwhile, the air on the other side of the ball is moving in the opposite direction, so the air flow separates.                                                                                                        Check the original article here: https://www.sciencealert.com/13-science-facts-never-learned-high-school-2018
