Written, Directed, Produced, Edited and Sung by Mitchell Moffit.
Based on the "Can-Can" music, by Offenbach.

LYRICS:

There's Hydrogen and Helium
Then Lithium, Beryllium
Boron, Carbon everywhere
Nitrogen all through the air

With Oxygen so you can breathe
And Fluorine for your pretty teeth

Magnesium, Aluminium, Silicon
Phosphorus, then Sulfur, Chlorine and Argon
Potassium, and Calcium so you'll grow strong
Scandium, Titanium, Vanadium and Chromium and Manganese

CHORUS
This is the Periodic Table
Noble gas is stable
Halogens and Alkali react agressively
Each period will see new outer shells
While electrons are added moving to the right

Iron is the 26th
Then Cobalt, Nickel coins you get

Ruthenium, Rhodium, Palladium
Silver-ware then Cadmium and Indium
Tin-cans, Antimony then Tellurium and Iodine and Xenon and then Caesium and...

Barium is 56 and this is where the table splits
Where Lanthanides have just begun
Lanthanum, Cerium and Praseodymium

Neodymium's next too
Promethium, then 62's
Samarium, Europium, Gadolinium and Terbium
Dysprosium, Holmium, Erbium, Thulium
Ytterbium, Lutetium

Hafnium, Tantalum, Tungsten then we're on to
Rhenium, Osmium and Iridium
Platinum, Gold to make you rich till you grow old
Mercury to tell you when it's really cold

Thallium and Lead then Bismuth for your tummy
Polonium, Astatine would not be yummy
Radon, Francium will last a little time
Radium then Actinides at 89

REPEAT CHORUS

Actinium, Thorium, Protactinium
Uranium, Neptunium, Plutonium

The Map of Physics Teacherflix 7 Views • 2 years ago

Everything we know about physics - and a few things we don't - in a simple map.

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.

How do Electron Microscopes Work? 🔬🛠🔬 Taking Pictures of Atoms Teacherflix 7 Views • 2 years ago

The nanoscopic world is wild!! Looking at basic objects like a grain of salt under an electron microscope looks like nothing you would have expected. Furthermore, have you ever wondered whether seeing a single atom is possible? Or how do scientists and engineers create only a few nanometers wide transistors? In this video, we will explore the electron microscope and how they are used to see nanoscopic objects. Specifically, we'll look at the Transmission Electron Microscope and the Scanning Electron Microscope and dive into how they work.

Rocks for Kids | Learn all about geology and rocks Teacherflix 7 Views • 2 years ago

Did you know there are three types of rock on this planet? In Rocks for Kids, you will learn all about how different kinds of rocks form. You will discover the properties and traits that make these rocks unique. And maybe you will find that being a geologist, a scientist that studies rocks, would totally rock!

Your kids will learn interesting facts about sedimentary rocks, metamorphic rocks, and igneous rocks. For instance, did you know that fossils are really only found in sedimentary rocks? You wouldn't find a dinosaur bone in a slab of marble. Speaking of marble, marble is a type of metamorphic rock. Metamorphic rocks form with really high pressure and heat beneath the earth's surface.

Igneous rocks actually divide further into two categories. There are intrusive (or plutonic) igneous rocks and extrusive igneous rocks. Intrusive rocks form when magma cools slowly inside the earth. An example of an intrusive igneous rock is granite. Extrusive igneous rocks form when lava cools really quickly. If lava cools fast enough, it creates obsidian.

We hope you and your student(s) enjoyed learning about rocks and geology! If you want to learn even more, head over to our website and download one of our many free lesson plans about different kinds of rocks, full of activities, worksheets, and more!

1992 Putnam with this problem:

A problem with a similar flavor came up on the 2005 Putnam A6. Give it a try! The solution for that problem, by the way, was written by Calvin Lin, a friend of mine who works at Brilliant. Small world!

If you want to check it out, I feel compelled to warn you that it's not the most well-documented tool, and has many other quirks you might expect in a library someone wrote with only their own use in mind.
