The Discovery of the Atomic Nucleus (3 of 15)

Published

on



Episode 3 of In Search of Giants: Dr Brian Cox takes us on a journey through the history of particle physics. In this episode we learn how Ernest Rutherford conducted a historical experiment that revealed that most of the mass of an atom is concentrated in a tiny nucleus made of protons and neutrons.

This film is part of a series originally broadcast on Teachers’ TV (

    how did discovery of nucleus contribute to science and how did it change the world??

    Please correct the closed captions. I have a hearing impaired student and would like to show this video, but many of the captions are nonsensical.
    Thank you.

    1XAJUMAMOY- So the correct placement of the electrons around a nucleus cannot be precisely located, but is like a large hamster ball around a little hamster…

    1XAPAZ: an insightful video about an experiment suddenly explained that the atom's mass is full of tiny nucleus that is made up of protons and electrons. it is amazing how these little particles are inside the living and non-living organisms, somewhat like planets and space particles in the galaxy, like our body is the milky way and these particles are like the planets and inside these planets are much more "smaller" things

    November 26, 2015 at 11:27 am

    1XASANJUAN: I've learned that in 1932, Rutherford and his colleague Chadwick discovered that the nucleus is made up of two particles: positively-charged protons and electricly neutral neutrons

How big is our planet? – (self experiment) | Breakthrough Junior Challenge 2018

Published

Is our planet infinitely big? NO, CERTAINLY! Then how big is it ?

Today satellites have enlightened us to get the exact picture of our earth. But 2200 year ago a man called Eratosthenes could find the Circumference of the entire earth using just SHADOW and HIGH SCHOOL MATHEMATICS with an error of less than 1%!!

And yes you can find the circumference of the Earth yourself !!!

Watch the video to learn more.

This is my first attempt in the Breakthrough Junior Challenge.

Thank you so much for watching!

I wish luck to all the fellow participant out there.

Who is Eratosthenes?
Eratosthenes was a mathematician and the chief librarian of the historic library in Alexandria. Eratosthenes was also termed as Beta, the second Greek letter as he was second best in everything after Archimedes. He developed a way to find prime numbers known as the Sieve of Eratosthenes. Find more of it on the internet.

Have you ever wondered where you live and what is hidden in the blackness of the cosmos? Is there any end or is it infinite? Where is the center of the universe? …or is there no center?
I am sure at least once you were thinking about it. In this video I will try to answer these questions.

This video was made for #breakthroughjuniorchallenge
Enjoy!
