## Stranger Things Math: Eleven and the Galton Board

July 3, 2022

NOTE: Michael (above), who seems appropriately scary for this post, uses a commercial Galton Board.  It has one flaw. Many balls feed into the grid at once and this will change the pathways taken because the balls bump into one another. The best results come from dropping in the balls one at a time. If you had the patience to drop in 3,000 balls one at a time.

More bear stats here.

# Brown Bear

Weight:  680kg

Height:   250cm

Top Speed: 35kph  = 10m/s

More bear stats here.

Comparing these speeds to the fastest man on earth, Usain Bolt:

# Usain Bolt:

Top speed: 243kph =   12m/s

So Usain Bolt could out run a Brown Bear but NOT a Grizzly!

## The Complaint: Everyone Hates Maths Anyway

………………………………………………………………….

## The Cause:

Students absorb maths fear and loathing from peers, siblings, parents and the culture. eg.

From the TwoFatDudes blog.

## The Solution:

Invite interesting guest speakers to talk to students. Other subjects do this. Bring in a cool young ex-student and attitudes can change, fast.

Otherwise show them these videos. The first video especially is AWESOME and totally, totally COOL.

## Cool Guys talk about Math:

Here are their blogs:

## Patrick JMT

Maths stories about death, tragedy and comedy in maths

## Tyler De Witt

On Scientific Notation

On Significant Figures and using significant figures this video has had 1 MILLION hits.

NO! This is not your homework. No stunts.

Just show us where you see maths in the world.

### 7c. Crack a Security Code for Middle School…… Yes! Really!
