Mathspig is in Melbourne, Australia. We’re in Lockdown. AGAIN!

And toilet paper has disappeared off the supermarket shelves. AGAIN.

So today we are doing maths based entirely on toilet paper using information from the Toilet Paper Fun Facts website. Yes! It exists here.

Tennis Math: Is player height a BIG advantage? USA units

February 13, 2021

Metric version here.

The Australian Open is on at the moment in Melbourne in LOCKDOWN. (We have 1 community-acquired case. Tennis players are in a bubble.)

Is height a BIG advantage in tennis?

Here are the heights of 3 top seeds in the Australian  Open. (See graph below)

No. 1 Novak Djokovic    6ft 1″  (73 in)

No. 6 Alexander Zverev  6ft 6’   (78 in)

No. 8 Diego Schwartzman  5ft 7’  (67 in)

1. Does serve speed increase with height?

That would be an advantage. Here is a Height vs Serve Speed chart for the Top 6 seeds in the tournament:

Find serve speed data here.

There is NO CLEAR HEIGHT ADVANTAGE for serve speed.

2. Does the serve return rate increase with height?

Here is Diego Schwartzman (L) when he defeated Alexander Zverev (R ) in the 2019 US Open.

What is Schwartzman’s Super Power?

Schwartzman, the shortest player on the circuit (see graph above), tops the service returns stats. Highest 2nd serve return rate. Third highest 1st serve return rate. See data below. So agility, speed, and reaction times are also important factors in becoming a tennis star.

Go Schwartzee! Check data here.

Godzilla vs Kong 2021: do the math! … USA Units

January 25, 2021

METRIC version here.

This is the teaser trailer for the Godzilla vs Kong movie out in MAY, 2021. The voiceover is a poem by UK poet W. B. Yeats called The Second Coming.

The poem is a truly horrifying reflection on WW1.

What would happen if a middle school student grew as much as GODZILLA!!!!!!

Might need bigger chairs at school!!!

 The problem for the 2021 film Godzilla vs Kong is that Kong has never been as big as Godzilla even in the obscure 1962 Japanese movie King Kong vs Godzilla (below).

So either The Zilla will have to shrink or Kong will have to grow for the 2021 film.  BUT HOW MUCH should Kong grow? Remember Kong was still a teenager in Kong Skull Island (2017) so he was still growing.
