The general idea of ​​the universe that the whole world knows was formed in the seventeenth century by Isaac Newton

00:06

I believe that the universe is a big machine that operates according to specific laws

00:11

If we know these laws, I can predict the universe in the future

00:16

Based on past and present information

00:18

Newton actually started making laws that describe everything in the universe, starting with the motion of matters, even the laws of gravity

00:25

Until a group of scientists such as Einstein, Niels Bohr, Max Planck and Schrödinger came and stated that the universe has no specific order

00:31

The things we are used to seeing are real. They are not real. There is no such thing as past, present, and future

00:40

The past can affect the present, the present can affect the future, and the future itself can change the past

00:46

This is the universe from the perspective of modern physics and quantum mechanics

“Sharafestien”

01:01

After the invention of the lamp in 1879, this is thanks to Thomas Edison, as he was the one who invented it and not someone else

01:07

All of Europe was happy that their lives would change

01:13

But they did not know that it was the beginning of the curse and that their joy would not be complete

01:19

Many questions were hiding in the dark, and when the city lit up, those questions began to appear

01:23

The idea of ​​making an Edison lamp is a wire that passes an electric current that heats it up and lights that wire

01:28

It was a very great idea, but scientists overlooked the positives and started asking questions

01:34

Why when the wire heated up the lamp lights up?

01:35

Why is the color of the light emitted by the wire different when the temperature is raised?

01:40

At first, the color is red, and when the temperature is raised, the color changes to yellow and then turns to white

01:48

[Awkward Silence]

01:50

Why the more and more you heat the wire, its color stays white and does not change to another color?

01:55

[Awkward Silence]

01:57

And why...

02:02

Those three questions no one knew the answer to, and whenever a person almost found an answer to a question, he would get a Nobel Prize

02:08

Scientists were aware that no one would be able to answer these questions unless they knew what matter is made of

02:13

Only then will they find an explanation for it

02:16

At the time, it was widely believed that matter consisted of small, round units resembling billiard balls

02:23

They cannot be divided and are neutral in electrical charges, that is, they are neither positive nor negative

02:28

These units are called atoms

02:31

Until a scientist came in 1897 to discover that the atom contains negatively charged balls

02:37

These little balls are called electrons

02:39

He stated that since the atom contains small balls of negative charge and the atom is electrically neutral, then the rest of the atom is positively charged

02:47

He stated that corn is like a watermelon

02:52

The black seed is the negative electron

02:54

And the watermelon is the positive charge

02:56

Then he won the Nobel Prize

02:58

Ten years later, another scientist named Rutherford came and had to make sure of this

03:05

So he brought a slice of gold and then directed it with alpha rays

03:08

It was found that the atom is similar to a watermelon, and most of it is positively charged, and the positive alpha rays that went to the atom bounced back again.

03:16

But he noticed that most of the alpha rays pass through the gold chip and a very small part is reflected
