Maths Cure for Wolverine

July 25, 2013

Jackie from Straight Ace Learning ( Maths & Movies ) asked Mathspig to come up with a formula for Wolverines super fast super healing powers. He can regenerate or heal in 5 seconds. In the latest Wolverine Movie he becomes mortal ….

Wolverine Facts:

No. Cells in a human/X-man Body

= 75 trillion cells  = 75 x 1012

(Mid-point of 60-90 trillion cells cited on the fab AskaBiologist website)

Imagine Wolverine is slashed/shot/wounded in the abdomen.

Human Trunk

= 44% of the body.

(See Body Segment Data here)

Estimate Cell Damage

= 1/4 of trunk = 44/4 = 11% = 0.11

Number Cells Damaged

= 75 x 1012 x 0.11 = 8.25 x 1012

You will need your Web 2 Scientific Calculator (See diag below).

W 1

W 2

W 3

This is what the calculation looks like on the WEB 2 Scientific Calculator. 

Tell MIDDLE SCHOOL STUDENTS that

 log2X

is just REVERSE ENGINEERING of

8 What the World Needs Now is More Parabolas

April 9, 2013

Maths-is-Awesome Activity

What the World Needs Now is More Parabolas

simpson's parabola

Skills: Graph, scale, measurement …. balancing that last cardboard section.

Level: Middle & Senior School

If you cannot make it to MOMaths Maths Museum in NY for a Mad Maths Monday, then you can run a Mad Maths Monday in your own class.

Build your own giant parabola out of cardboard.

We’re being awesome

We’re thinking big.

Make it big enough to arch over the front door of the school.

Morph Me

July 6, 2012

Here is LAGA Phd student Attouchi @ the 13e Salon Culture & Jeux  Mathematique in Paris.

She was showing students how to use a graph to create anamorphic projections. This is interesting maths!!!

Here is an anamophic projection painted by extraordinary  Australian artist Juan Ford. Mathspig went to Juan’s amorphic projection show. Now that I’ve tried to do one by hand, I have more respect. It’s totally tricky, but doable.

You will find more of his anamorphic projections @ artabase

Conformal Mapping

In maths we call this type of image distortion CONFORMAL MAPPING.

Mathematicians write equations for conformal mapping, which means they produce equations that can  turn your picture into an image you might see reflected in a fun park mirror or even in pond ripples.

Here are some images created by Wei Zeng, Lok Ming Lui, Xianfeng Gu, Tony Chan and Shing-Tung Yau who, as mathematicians would say, create Quasiconformal Maps Using Discrete Curvature Flow. You’ll find more here.

Here is the mapping graph used by Attouchi to create Anamorphic Projections.

…………………………………………….

 

All you need is this grid (Download pdf file here Anamorphose Cylindrique) and a cardboard tube ( Diam 47mm or a little bigger than a toilet roll tube) covered in shiny silver paper (as used in He balloons or use gift wrap paper.)

You can just see the dotted line indicating where to place the tube mirror on the grid.

But don’t be mislead. Creating anamorphic projections is really tricky. Mathspig nearly blew a fuse trying to do a drawing. In the end I decided to keep it simple and use letters. Students could start with a triangle or their name. Keep it simple mathpiggies!!!!!! But it is such fun.

Ooops! Mathspig forgot to write Maths 4 Eva as a mirror image. Take 2:

It works!!!!!
