## Real World Maths: Gotye and Some \$\$ that he got to know

November 12, 2020

Melbourne singer, songwriter, and geometrically inclined performer Gotye performing with Kimbra won 3 Grammy Awards for his song Somebody that I used to Know in 2013.

The Gotye youtube clip has had 1,535,344,012 or 1.5 Billion hits since it was first uploaded 5th July 2011.

## Mini Rates Exercise:

In 111 months Somebody that I used to know has scored 1.5 Billion hits. How many hits a. per month, b. per day, c. per minute? (Round off numbers)

Ans: a. 13.5 Million per month

b. 450,000 per day (Assuming 30 days per month)

c. 37,500 per hour and 625 per minute (for over 9 years non stop!)

## Estimate of Youtube Earnings for this Song:

The Influencer Marketing Hub puts the rates an advertiser pays between \$0.10 to \$0.30 per view on Youtube, but averages out at \$0.18 per view. Using the lower rate, how much has this song earnt in just over 7 years?

Earnings = 0.10 x 1.5 x 10 = 1.5 x 108     = \$150,000,000  = \$150 million*

*This calculation is based on a click per view of the video.  Gotye will not receive anything like \$150M, however, because advertisers pay per click on their ad.

According to the Influencer Marketing Hub again ‘on average, the YouTube channel can receive \$18 per 1,000 ad views. This equates to \$3 – \$5 per 1000 video views.’ Again, using the lower rate:

Video Hits =1.5 x 109

Divide by 1,000 = 1.5 x 10÷103    = 1.5 x 106

\$3.00 per 1,000 video clicks earnings = 3.00 x 1.5 x 106   = 4.5 x 106

Realistic Earnings = 4.5 x 106    = \$4,500,000  = \$4.5 million

## A Geometric Parody:

Here is Mathspig’s take on the song:

## Somebody that I used to Know:

It’ll either help students do their exercises or work like Clockwork Orange and have them running screaming out of the room when they hear the first few notes.

# ………………..How much money does a popular

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

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 to pig out and save the planet

January 2, 2015

Aussie physicist and TV present – that does sound like an oxymoron – Reuben Meerman (A meer man after all. Old joke) had an article published in the BJM (British Medical Journal) with Andrew Brown describing where fat goes when you lose it.

When you burn fat which is a triglyceride or a three-pronged hydrocarbon the formula is:

You breath out the FAT as CO2 and H2O.

BUT:

Oxidizing 10 kilos of human fat requires inhaling 29 kilos of oxygen to produce 28 kilos of carbon dioxide and 11 kilos of water. You can check out how much carbon dioxide you add to the atmosphere when you diet in the following graph:

When you lose weight you add carbon dioxide to the atmosphere, but when you gain weight you take carbon dioxide out of the air. Your carbon footprint from Time for Change blog (See table below) can be neutralised if you put on the following weight:
