Happy Pi Day! Ooops! Not you Germany!

March 14, 2019

There is a fab article on the History of calculating pi in the New York Times today.

Now to THE FUNNY SIDE OF PI DAY

In Australia we don’t get too carried away with 14 March aka Pi Day aka 3.14.19 because, unlike Americans,  we do not write the date as 3/14/19. We prefer 14/3/19.

No problem.

Meanwhile Mathspig called her  talk for the International Congress of Mathematical Education 2016 in Hamburg:

How many m&ms would kill a 14-year-old? Making middle-school maths real, relevant, deadly serious and π-in-your-face funny!

Then  odd emails arrived relabelling my talk  ‘…….. p-in-your-face funny!’

I thought it was a typo. Not so! The Germans, the Dutch and other European countries do not call π ‘Pi’, they call it ‘P’ or ‘Pee’ because ‘i’ is pronounced ‘ee’, for instance, in German. So I had called my great international maths talk Pee-in-your-face funny! And the German organising committee seemed happy enough with the title.

To be diplomatic and to avoid the attracting the wrong type of audience I’ve retitled my talk:

How many m&ms would kill a 14-year-old? Making middle-school maths real, relevant, deadly serious and ha^2 funny!

So Happy π Day English speakers and now, for a laugh, look at some of our Pi or Pee jokes through the eyes of, say, a German.

Pi Day 2

That’s because of the beer.

Pi-Day

One whole day dedicated to pi.

It’s epic!

Pi Day 3

Mathematicians in love .., awwww!

So cute or they’re pissed.

………………………………………..

Pi Day 4

OK. ‘I 8 sum pi’ but adding the ‘delicous’ makes this weird for a German. D’Oh!

pi Day 5

Very expensive bottle of pi.

Pi day 6

Mmmm! Pecan pi.

Pi Day 8

Rabbit Pi must be a problem.

Pi Day 10

Dessert wine, maybe?

Pi Day 9

That’s, like, every day after a night out on the ‘piss’ as we so delicately call it in Australia.

pi Day 11

You too can have tasty pi. I don’t know how and frankly, I don’t want to know.

Use the WIFI Force, Luke!

February 23, 2017

So you have cracked the WIFI password (above). It’s time for some Fun, Fun, Funnies.

Here are Mathspig’s favourite WIFI names:

Weird 1:

Google Image this number: 241543903

It leads to a meme of people posting ‘put your head in a refigerator’ selfies. Why? Dunno.

Weird 2:

Google: Definition (Defn will do) of ‘askew’.

The Google page is askew!!!! Really. What is the angle of the page below horizontal. You can work it out.

3. Anamorphic Cube

February 11, 2016

10 Amazing ways to see a cube

This is quite a challenge. The idea is to draw an anamorphic cube so that the image, once projected onto a curved surface looks like a cube. You will find the template or graph for this exercise on Mathspig here.

It took me several goes to get it … sort of … right.

Mathspig Cube 3.1

Step 1: Make silver foil/cardboard cylinder to fit the dotted circle on the grid below.

Mathspig Cube 3.2

Step 2: Draw in the corners of the cube on the square grid and match these corners on the curved grid.

Mathspig Cube 3.3

Step 3: Draw in the three vertical sides of the cube and match these lines on the curved grid.

Mathspig Cube 3.4

Step 4: Draw in the top and bottom horizontal sides of the cube on the square grid and match these on the curved grid.

Getting tricky now.

Mathspig Cube 3.5

Step 5: Draw in the blue, orange and green sides of the cube on the square grid and match these on the curved grid.

Mathspig Cube 3.6

Step 6: Place silver cylinder on dotted circle.

Mathspig Cube 3.7

Step 7: Can you see the cube?

Mathspig Cube 3.8

Step 8: Here’s a closer look.

An even better Anamorphic Cube.

HOW MANY BAD HAIR DAYS in your life?

According to The Manchester Confidential a consumer survey found that the average British female will endure 7,332 bad hair days in a lifetime!!!!

How many years is that? Do the maths.

7,332/365 = 20.09 years 

0.09 x 365 = 32.85 = 33 days

O MY GOODNESS, 20 years and 33 days of BAD HAIR. 

Makes you wanna go back to bed or shave your head.

Hair Maths 4: The Great SHAMPOO rip off

April 27, 2015

According to Salon.com:

There are two types of ingredients in shampoo. One type cleans your hair. The other type strokes your emotions.

Hair Maths Mathspig

Shampoo has one main ingredient:

DETERGENT

The two most common shampoo detergents are ammonium lauryl sulphate and ammonium laureth sulphate. That’s all you need to clean your hair. All those shampoo bottles. All that supermarket shelf space offer THE SAME PRODUCT.

Mathspig Colin Farrell shampoo

Other ingredients include: perfume, dye, preservative, foaming agent, acid (The problem is hair swells in an alkaline solution eg with soap when rinsed out the hair shrinks making knots impossible to brush out. ARggghhhhh!), thickeners, thinners, sheen additive, pearlesence powder (makes shampoo look pearly) etc

According to Steve Antczak, Co-author of Cosmetics Unmasked: Your family guide to safe cosmetics and allergy-free toiletries,

A typical shampoo is mostly water, containing between 5 and 20 per cent detergent, with shampoo for dry hair containing less detergent than shampoo for greasy hair.

See New Scientist, Sept , 2009

So the potency of shampoo looks something like this: 

Mathspig % detergent in some shampoos 1

Assume you buy a 500ml bottle of shampoo for $10. Now you can work out how much some shampoo manufacturers rip you off by filling in this table:

Mathspig % detergent in shampoo Q
 

How much do you pay for water in shampoo? The Answer is here. Mathspig % detergent in shampoo ANS 

What does Bill Bunn from Salon.com recommend?

My new shampoo, Sunlight Dish Detergent, has just four ingredients. It’s runny and slightly acidic, smells vaguely lemony, doesn’t foam excessively and looks anemic.
