The story of Rutherford and quantum mechanics

I’m not a physics major, but today I came up with an article on quantum mechanics :)
@hunhani wrote a profound article on quantum mechanics, but I’m about to introduce the story of the scientist Sir Ernest Rutherford who contributed to the advancement of quantum mechanics! If you’re interested in science, keep up with my fun science articles. If I have written anything incorrectly, please let me know :)

There is a statue of a boy.

Sir Ernest Rutherford (1871~1937)
Ernest was the child of James Rutherford and Martha Thompson. His father did all kinds of work including farming, and his mother was a school teacher.
He was the fourth kid of the twelve children.
Twelve? His mom was one hell of a woman...
Rutherford went to the Cavendy laboratory at the University of Cambridge, supported with the British scholarship and a world fair scholarship.
Originally, another student was nominated as a scholarship student. But that person married and decided to stay in New Zealand. That’s the behind story of how Rutherford became a scholarship student.
Lucky!
Nah, Britain is lucky :)
The Cavendish laboratory is the laboratory that won 29 Nobel prizes with the 6,300 pounds that William Cavendish donated. Twenty nine! (Rayleigh who discovered Argon, Thompson who found the electron, and Watson & Crick who found the double helix structure of DNA and so on.)
Wow, 29 from one laboratory! Impressive!
But after 1989 there were no more Nobelists :(
The time when Rutherford went to the Cavendish laboratory was when JJ Thompson was in charge, after Maxwell and Rayleigh
That year Conrad Röntgen found the X ray!
Röntgen : ‘Dunno what it is but it exists! Let’s name it X ray…’
Now it’s used for lots of areas like X ray examinations, CT scanning and others.

The following year, Antoine Becquerel found radiation coming from uranium.
Becquerel: ‘I named it the Becquerel ray…’
Rutherford also dived in to the study of radiation. He studied the radiation coming from the uranium and discovered that the ray wasn’t singular.
There were two kinds of rays.
One that was blocked by paper and one that went through. There were also types of radiation that were blocked by thin metallic plate such as aluminium, and there were radiations that went through aluminium. He named these types of radiation alpha, beta, and gamma ray.
Rutherford made the alpha ray pass the magnetic field to verify the properties of it. According to Michael Faradey and James Maxwell an electron bends in the magnetic field. J.J Thompson has found the negative electron using these properties.
The alpha ray bent in the opposite direction of the electron. It had positive electricity. It didn’t bend as much as an electron but it was heavier.
As he measured the quantity of electric charge, the charge of an alpha particle was +2e while the charge of an electron is -1e.
Rutherford thought of another experiment that involves using the alpha particle. The experiment shook the notion of what atoms look like.
Please let me know if anything has to be corrected :)

Very nice post on Rutherford.
Maybe one precision that you would like to add to your post: Rutherford contributed to the birth of quantum mechanics in some way, definitely, but he is not the one behind. His discoveries led Bohr to define the so-called Bohr model for explaining what is going on. Bohr's model is known as the old quantum theory. In short, the theory that has been replaced by quantum mechanics.
I have a never-ending project of writing a quantum mechanics course on Steemit (okay I started months ago and things are not progressing too fast). Feel free to have a look if you are motivated. There are already nine episodes around ;)
Thanks for the reply. In the next article, Rutherford, Hans Geiger and Ernest Marsden will appear. The atomic model story of Niels Bohr will also appear. I appreciate your interest, and I will read your post hard. Thank you.
My pleasure :)
great
thank you!
Rutherford quantum mechanics really helps the science a lot, but there has less people who talk about it.
UPVOTED.
very good.
I would be happy if you like to follow me and give your opinion about my posts.
Thanks.
