Amazing Incredible Science Facts

1. Watch it – Water can boil and freeze at the same time


When a liquid or water can boil and freeze at the same time is called the ‘triple point’, and it occurs when the temperature and pressure is just right for the three phases (gas, liquid, and solid) of a substance to coexist in thermodynamic equilibrium. This video shows cyclohexane in a vacuum.

2. Laser light can get trapped in a waterfall


Not only is this an incredible example of total internal reflection, it also shows how fibre optic cables work to guide the flow of light through water etc.,

3. We’ve got spacecraft hurtling towards the edge of our Solar System really, really fast

We all know rockets are fast, and space is big. But sometimes when we’re talking about how long it takes for us to get to distant parts of the Solar System (eight months to get to Mars, are you kidding me?) it can feel like our spacecraft are just crawling along out there.

The above figure shows just how wrong that idea is by comparing the speed of the New Horizons probe, which flew past Pluto the last year, to a 747 and SR-71 Blackbird.

4. An egg underwater looks like a crazy jellyfish


Yes, A cracked egg on land might make a big mess, but 18 metres (60 feet) below the surface of the ocean, the pressure on the egg is 2.8 times the atmospheric pressure, and it holds it all together like an invisible egg shell. It’s True.

5. You can prove Pythagoras’ theorem with fluid


Not buying what your maths teacher is selling when they tell you a2 + b2 = c2? You can actually prove it with liquid.

6. This is what happens when a black hole swallows a star


As the star gets sucked up into the black hole, a huge jet of plasma is burped out, spanning hundreds of light-years. “When the star is ripped apart by the gravitational forces of the black hole, some part of the star’s remains falls into the black hole, while the rest is ejected at high speeds,” explains Johns Hopkins University researcher, Suvi Gezari.

7. You CAN see without your glasses

According to Minute Physics, 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.
