Fingerprints

So, apparently the reason we have fingerprints is unknown. Scientists thought that it was to have better grip on dry stuff, but that has been proved wrong. So here we go.

Movement. That is the reason why. We grasp, grab, squeeze, hold, pinch, pull and do a lot of other things with our hands that require to move our hands. and your finger prints are so the skin can move closer or spread apart when we do something. Have you ever had a blister on you hand, and popped it? well, have you noticed how that skin feels when you pick something up. it feels weird. that is because the skin can't separate or "close"  as good as the regular skin with you fingerprint. The new layer of skin is smooth, so the skin has to either rip, or bump up. But the ridges of the fingerprint allow for it to curl together or spread apart. Like when you have a shoe with those bumps, it is there so the shoe can flex better than a shoe without. That is it. And the reason for everyone's fingerprint to be different, is because you try to put together two artificial hands, made of millions and millions of tiny building blocks, and tell me when they are EXACTLY the same.

The Mpemba effect

Hey,

So we have the Mpemba effect, which most of you have probably heard.

The Mpemba effect is how hot water freezes faster than cold water. But not like this:

8oz of water at 90°c, marked a, is put in a freezer. Another 8oz of water at 30°c, marked b, is put in the same freezer, at the same time. 5 minutes later, when the freezer was opened, the cup marked a was frozen and the cup marked b was not.

No. we are talking about the rate that it freezes, not the overall time.

This happens because heat goes up and cold goes down.

So you put your cold water in the freezer, and as it is in there, the cold water goes down, and the warmer water goes up. After some time we get some small pieces of ice. This ice floats to the top, as it is less dense the liquid water, and after some time we get water.

Now you put a cup of hot water in the freezer, and when it is in there the heat travels up, forcing the colder air down to the water, due to diffusion in the air, causing more colder air to hit the top of the cup. Now because we have that cold air, it cools the water,  so the top is now colder than the bottom, and we have the colder water go to the bottom and the hotter to the top. this goes on and on and on, which makes the cooling process go by faster.

And that is the answer to the Mpemba effect.

Interactions

What's Up,

What do you guys want me to do theories/explanations of. Like chemistry, math, astronomy. It's up to you, I mean: why would I post stuff that no one cares about or stuff that no one wants to know. So tell me what you guys want me to post.

Connor's Big Bang Theory

What's Up,

So I have had my theory, as well as every other person out there, on what caused the big bang. The big bang has mystified scientists for as long as we discovered it. Now we know what actually caused the big bang, it is having a point of extreme heat, density, and some other stuff. This caused so powerful forces to combine causing the "explosion" that created the universe. But what caused that? Well, hold on to your seats cause here we go:

Black holes.

A point in space of infinite density, where a star ran out of fuel, causing it to become to dense and crushing itself to a single point under it's own gravity. well we all know how they are made and what they are. But what I have never seen or heard is their part in the big bang. Think about it, black holes are unstoppable, even to light.

So my theory is that after a long time, the universe has one black hole, now this bad boy moves around a bit, "sucking" up some other stars, planets and other space junk. then more are made, and more, and more. So eventually we have a lot of unstoppable black holes. After a while, A long time (I.E. not even after our solar system dies), and all that is left is these black holes. The reason for everything being gone is everything has been absorbed by these black holes. So after some more time, these black holes come closer, and combine. So then after some time we get like 5 GIGANTIC super black holes, then 2 combine, so 4 are left over. Then more combinations to have only 2 of these black holes left over. From the entire universe, from stars to planets to galaxies. Only two black holes. The last two thing in from this giant universe combine. leaving everything in one point.

Everything in one point. The reason for the Big Bang. This my friends is what caused the Big Bang, the thing that started the universe, to happen. This is the answer that scientists have been searching for. What Caused everything.

Now because history repeats itself, this will probably happen to our lovely universe, and to the next. In an infinite loop.

And that is the answer to the Big Bang.

The Last Digit of Pi

What's Up,

So lets talk about pi. 3.14159 (To see even more click here). We all know it as it was taught to us in elementary school. We were told that it goes on forever. But does it? I mean honestly it has to stop somewhere. Everything has an end. Well, I can say that I know the last digit of pi. you see it is zero. Honestly. It is, Because LOGICALLY speaking if you add a zero the the end of any decimal, it stays the same. So the last digit of pi is zero. And I know that someone out there will be saying " Well if it is infinite, then it isn't zero". Well actually it is, because if it is endless, then it does not have a last digit, so theoretical i would still be right. For example, you could say that your third leg is blue, people would find it weird, but if you have no third leg, then anything you say about it is true, except if you say that it is real. Because if it does not  existence, then it is everything, technically.

And that is the last digit of Pi

Welcome

What's Up,

I'm Connor, and welcome to Connor's Logical Science. Here, I will post a bunch of theories that I have made, most of them will be 100% logic. So welcome and lets get started.
