Errata and clarifications.

I endeavour to be as accurate as possible in my videos, but I am human and definitely don’t know everything, so there are sometimes mistakes. Also, due to the nature of my videos, there are bound to be oversimplifications. Some of these are intentional because I don’t have time to go into full detail, but sometimes they are unintentional and here is where I clear them up.

1. “Isaac Newton invented calculus.” Actually there is controversy over who invented calculus first Isaac Newton or Gottfried Leibniz. Regardless of who it was I have used Leibniz’s mathematical notation here and so he definitely deserves credit. I did’t know about all this so thanks to those who pointed it out. https://en.wikipedia.org/wiki/....Leibniz%E2%80%93Newt
2. “Maxwell derived the laws of electromagnetism.” This is a simplification as Maxwell’s work was built on the backs of other scientists like Hans Christian Ørsted, André-Marie Ampère and Michael Faraday who discovered induction and saw that electricity and magnetism were part of the same thing. But it was Maxwell who worked out all the maths and brought electricity and magnetism together into a unified theory. https://en.wikipedia.org/wiki/....Electromagnetism#His
3. “Entropy is a measure of order and disorder”. This is also a simplification and this does a good job of explaining it better https://en.wikipedia.org/wiki/Entropy
4. Einstein and Quantum physics: I made it sound like quantum physics was built by people other than Einstein, but this couldn’t be further from the truth. Einstein got a Nobel prize for his work on the photoelectric effect which was a key result to show the particle-like nature of light. Funnily enough he never got a nobel prize for his work on Relativity!

Also, if you enjoyed this video, you will probably like my science books, available in all good books shops around the work and is printed in 16 languages. Links are below or just search for Professor Astro Cat. They are fun children's books aimed at the age range 7-12. But they are also a hit with adults who want good explanations of science. The books have won awards and the app won a Webby.

This video covers:
- How stars form, live and die
- How they transition between a nebula, protostar, main sequence star
- And then either red giant, white dwarf and black dwarf
- Or red super giant, supernova, and then neutron star or black hole

Music plays a big part in many of our lives. Whether you just like to listen or you enjoy playing an instrument, music is powerful. So what is music? How does it work? What are the physics of music? In this episode of Crash Course Physics, Shini talks to us about how music functions in terms of waves and how these waves interact with our ears.

In this video, we look at how particles move in gases and how this leads to gas pressure. We then explore how changing the temperature changes the kinetic energy of the gases and how this changes the pressure.

I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of Crash Course Physics, Shini talks to us about just that.

#gravity #science #song
A song I wrote to introduce my elementary students to the concept of gravity and to 'maybe' explain why I'm always falling down! (lyrics below)
From Newton's basic laws of motion.
LYRICS
Gravity is all around,
When I fall it pulls me to the ground!
A force that you and I can’t see,
Pulls me toward you, and you towards me!
Keeps us from flying into space,
Why I fall when I trip on my shoelace,
That cool force is gravity,
Thank Isaac Newton’s apple tree!

Gravity,
A force that’s pulling you and me,
Gravity,
Pulls Jupiter, Mars, and Mercury,
Gravity,
A force that’s pulling you and me,
Down and down,
As our Earth spins round and round…

I fall,
You fall,
We all fall down!
The force of gravity
Pulling us to the ground,
You can never see it,
It never makes a sound,
It makes our mother Earth,
Go round, and round and round,
The planets have their orbits,
Because of gravity,
Pulls on flying objects,
Pulls on you and me!
Makes an apple fall,
Lets us slip down slides,
Makes a yo-yo go,
And oceans have their tides!
Gravity, we all fall down!
Gravity, we all fall down!
Gravity, we all fall down!
Gravity, we all fall down!

Hey gravity, hey gravity hey,
Don’t make me fall down today!
Here’s the reason, why I’m scared,
32 feet per second squared!
Hey gravity, hey gravity hey,
Don’t make me fall down today!
Here’s the reason, why I’m scared,
32 feet per second squared!

Gravity,
A force that’s pulling you and me,
Gravity,
Pulls Jupiter, Mars, and Mercury,
Gravity,
A force that’s pulling you and me,
Down and down,
As our Earth spins round and round…

Pulls Jupiter, Mars, and mercury,
And all the planets I can see,
Pulled in orbits around the sun,
The sun is pulling everyone?
Sun has so much gravity,
A whole bunch more than you and me!
Great big mass, big gravity,
I’d weigh much more on the sun you see…

I’d weigh much more,
On the sun you see,
Great big ball of mass,
Means more gravity,
The great amount of mass,
Means the greater the pull,
A dog has less mass,
Than a cow or a bull!
It’s not too strong,
But it’s all around,
If it was real strong,
We couldn’t jump up off the ground,
Gravity’s good,
Based on mass not girth,
Gravity’s good,
It holds us to the Earth!

Gravity, we all fall down!
Gravity, we all fall down!
Gravity, we all fall down!
Gravity, we all fall down!

When you hear the word "work," what is the first thing you think of? Maybe sitting at a desk? Maybe plowing a field? Maybe working out? Work is a word that has a little bit of a different meaning in physics and today, Shini is going to walk us through it. Also, energy and power!
