This month, Matt and Bec explore voting systems in elections. Bec wonders what effect it might have to vote for a novelty candidate. And we speak to a special guest who might just know a thing or two about this.

Plus a whole heap of quick-fire problem solving!

Here's the video Matt mentioned that simulates alternate voting systems: https://www.youtube.com/watch?v=yhO6jfHPFQU&ab_channel=Primer

013 = Heavy Lifting and Clever Gifting30 Nov 202000:55:57

What's the most cunning way to move furniture on your own?

Thoughtful ideas for Christmas presents

Answers to the riddle of Pudding's Wheel, including a brilliant piece of maths by a listener.

Recipe for microwave fudge:
3 cups of milk or dark chocolate bits (roughly 500g)
1 tin condensed milk
1/4 cup of butter
Step 1. Microwave all ingredients for 3-5mins, stopping to stir occasionally.
Step 2. Grease or line a deep tray/dish with baking paper and pour in the mix.
Step 3. Refrigerate.
Step 4. Once firm, cut into squares.
(Note from Bec: in Step 2, I like to dust the baking paper with cacao powder and then dust the squares again once cut in Step 4. It helps stop them from immediately melting back into each other. You can also add nuts and dried fruit or spices if you want to get experimental. Make sure you store this in the fridge whenever possible, as it has a low melting point!)

012 = Series of Teeth and Queries of Cheese31 Oct 202000:59:56

To celebrate 12 episodes we're collecting some data! If you can, fill in the listener survey: http://thatsurvey.ilikeit.aproblemsquared.com

Does this cheese look like it has 41% less packaging? https://www.dropbox.com/s/kuj16lmkgrx8w7i/41cheese.jpeg?dl=0

Here's the wikipedia page we used to make sense of shark teeth: https://en.wikipedia.org/wiki/Shark_tooth#/media/File:How_to_count_shark_teeth.png

The Weaire-Phelan structure: https://en.wikipedia.org/wiki/Weaire%E2%80%93Phelan_structure

What a truncated octahedron looks like: https://en.wikipedia.org/wiki/Truncated_octahedron

And a spinning one! 

https://upload.wikimedia.org/wikipedia/commons/7/7c/Truncatedoctahedron.gif

MATT'S CALCULATIONS
A 140mm × 60mm × 46mm block of cheese has a volume of 386.4 cm^3 and a surface area of 352 cm^2. To give a 41% reduction the original needs to have the same volume of cheese but an area of 596.6 cm^2.

Matt assumed there are 4,200,000 current infections and each person has 400,000 virus particles per mL across 2L of fluid. If the SARS-CoV-2 particle has a diameter of 150nm and stacks like spheres with 74% efficiency: those 3,360,000,000,000,000 current virus particles would fill only 8mL, aka "about a teaspoon".

Bec Hill: http://bechillcomedian.com/
Matt Parker: http://standupmaths.com/

CORRECTIONS:

01:04 Matt says "early adapter" when he means "early adopter". But it could be both. It’s a podcast that changes you.

18:08 Bec says "4" instead of "6". Don't worry: the maths was all ok. Phew.

26:22 Bec says "implicit permission" when she means "explicit permission". She will definitely double check before she repurposes any one else's teeth.
