# And the Oscar for Best Mathematical Performance Goes to …..

# Ben Zauzmer

**Ben Zauzmer, a Harvard Applied Math graduate who has a 75 per cent success rate in predicting the winners of Oscar Awards every year, has correctly predicted 20 of 21 winners in 2018 Oscars, which is a success rate of 95%. **

**How does he do it? He gathers thousands of data points on Oscar ceremonies over the past two decades – such as categories movies are nominated in, other award results, and aggregate critic scores – and he uses statistics to calculate how good a predictor each of those metrics is in each Oscar category. Then, he plugs in the numbers and that gives him the % chance that each film will win in each category according to the Boston Globe.**

**Ben, who writes for The Hollywood Reporter, uses his mathematical model to produce Bar Graphs like this:**

**This year the Best Picture was a close call, but Ben’s Mathematical Prediciton was correct. **

## 6. You’re either Good at Maths or You’re Not

September 20, 2017**The Complaint**:

**You’re either Good at Maths or You’re Not!**………………

### ………………………………………………………………………….

**The Cause**:

#### Most students who said “I can’t do maths’ when I was teaching, didn’t do maths. They talked, penned a tattoo on their arm. Or scribbled in the text book. Today they read texts or play games on their phones under table or fall asleep.

### ………………………………………………………………………….

**The Solution:**

#### There is no point arguing. Students must ‘see’ they can do maths.

#### Do something that grabs their attention, something counterintuitive. Here is one of the BEST revision projects ever for middle school maths students. Remember, the best way to learn something is to teach it.

### 8c. What Volume of Alcohol is Lethal?

## 8a. Calculate Your Daily Iron Intake

August 19, 2017# The Complaint

## 8a: When will I EVER use this maths?

# The Cause:

#### Students doing repetitive text book exercises without using maths to solve REAL WORLD problems.

**The Solution:**

## You are going to use this maths NOW.

# Calculate Your Daily Iron Intake

# TOPICS: Decimals, %, weight units (METRIC)

Some information you need.

Iron (Chemical symbol:Fe) content in food is recorded in mg because there are only small amounts of iron in food.

1 g = 1000 mg

eg. 1 paper clip = 0.5 g = 500 mg

Iron in 2 teaspoon peanut butter = 0.19 mg

## YouTube Clip Money Making Maths

June 26, 2017# ………………..How much money does a popular

# ………………………YOUTUBE clip make?

You will learn everything you need to know at **1 Million YouTube Views. ** Now let’s do the maths!

Here are the TOP 3 **YouTube Clips Ever**. Their popularity is measured by Number of Views.

# 1. PSY – GANGNAM STYLE

# 2,879,287,942 views

View **here**.

# 2. Taylor Swift – Blank Space

# 2,088,564,435 views

# 3. Wiz Khalifa – See You Again. Charlie Puth (Furious 7)

# 2,850,776,581 views

View **here**.

YouTube uses an algorithm (ie. a formula) for calculating the amount of income earnt by a clip from advertising. There are multiple issues involved including how long viewers watch the ad, the demographics (age group) and the actual sales (Retailers actually do review ad costs vs increased sales. Always. They are not idiots.)

Here is the basic method used to calculate ad revenue for a Youtube creator. Remember, a creator must have a minimum of 10,000 hits on their channel before any revenue is paid.

Of course, pop stars use Youtube as a promotion platform. They can earn money through multiple Youtube clips, sponsors, merchandise and live perfomances. Nevertheless, it is surprising how little money is earned by each clip.

eg. ONE DIRECTION

## How Oops! Try again Maths is killing us …………………………………………………………………………… MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig MathsPig ….…. with Kerry Cue

September 8, 2015# The New Age of Guess-amatics!

Hellooooo Sweeties,………………………………………………………………………

Some frightening maths this week. When researching DANGEROUS MATHS, Mathspig found one branch of maths is the most dangerous maths of all. Let’s call it GUESS-AMATICS. Today, maths is often taught via computer program packages. Some of these computer packages turn maths into a guessing game.

This exact and rather frightening scenario was described to me by the mother of a 5 year old. The mother decided it was time to turn the game off. When students play mathematical computer games too often they don’t have to think, they just guess the answer and try again. But be warned this ‘Oops! Try again’ maths can kill you’! Some maths you cannot ‘try again’. You HAVE to get it right the first time. Medication is one area where ‘Oops! Try again maths kills”

# Do the Maths and Do NO HARM.

You need sufficient maths to understand medication doses or you might do yourself harm.…………………………………………………………………………………..

**And here is just one very frightening statistic:……………………………………..**

According to FDA data 1.3 million people in the USA are injured each year from medication errors.

Meanwhile, we need nurses, caregivers, doctors, paramedics, First Aide volunteers, parents, grandparents, babysitters, teachers and all health care professionals to have sufficient maths to be able to calculate simple medication doses. Or we need them to simply READ the dose and make sure it is correct. Unfortunately, many of those who should be able to work out medication doses are either incapable or not paying attention. And your life could be in their hands:

# UK

**In the UK 1 in 20 hospital deaths is due to medical error. Nearly 12,000 patients die needlessly in hospital every year due to blunders by staff, researchers warn.** **Drugs or fluid mismanagement was identified as a problem in 21% of preventable deaths (NHS 2012) or, doing the maths, 21% of 12,000 is approx 2,500 deaths due to bad maths!**

# USA

**According to a new study just out from the prestigious Journal of Patient Safety, four times as many people die from preventable medical errors than we thought, as many as 440,000 a year.**

# Canada

**Reports show between 9,000 and 24,000 hospital deaths due to medical error.**

# Australia

**Official Australian government reports reveal that preventable medical error in hospitals is responsible for 11% of all deaths in Australia or 1 in 9 deaths.**

Dangerous Maths 1:Young drunk dead

Dangerous Maths 2: Death by Snake, Spider, Quad bike, Kangaroo, Raccoon and Vomit

Dangerous Maths 3: Shark Attack

Take care and do the maths……………………………………………………
