mathspig world 2

Hellooooooooo Sweat Peas,

If you counted @ the rate of 1 number per second …. That’s 7 Billion seconds 

or (rounding off) 117,000,000 mins

or 1,944,000 hrs

or 81,000 days

or 221 years !!!!

Oooooooo! But this is sloooooow counting. 

How fast can you count?

You’ll find an online stop watch here.

Time yourself counting to 60. This will give you your count rate (60/time = rate nos. per sec)

Now you can calculate how long it would take YOU to count to 7 Billion.

Who is the fastest counter in your maths class?

More population maths follows.

Bye-de-bye

Can You Die Laughing, Sir?

May 4, 2012


.

.

The.skeptics acknowledge two recorded cases of death by laughing. On 24 March 1975, Alex Mitchell, a 50-year-old bricklayer from King’s Lynn, England, died laughing while watching the “Kung Fu Kapers” episode of The Goodies, featuring a kilt-clad Scotsman with his bagpipes battling “Ecky Thump”, who was armed with a black pudding

and

Damnoen Saen-um, a Thai ice cream salesman, is reported to have died in 2003 while laughing in his sleep at the age of 52.

 …………………………………………………………………………………

Wikipedia claims one American died in 2012 from laughing. This claim cannot be confirmed.

 Even if one case was reported look at the odds or probability:

Die Laughing : 1 in 7,000,000,000 for the World

or 1 in 310,000,000 in the USA.

This is a much lower probability according to Oddee than dying in the USA from:

Roller Coasters

1 in 77.5 million

Vending Machines

1 in 24 million

 Falling out of bed

1 in 690,000

Texting while driving

1 in 62,000

Meanwhile LiveScience puts the probability of dying in the States from:

……………………………………………………………………………………………………………………….

Legal Execution*

1-in-58,618

Tornado

1-in-60,000

Lightning Strike

1-in-83,930

Snake, Bee or other Venomous Bite or Sting

1-in-100,000

Earthquake

1-in-131,890

Heart Disease*

1-in-457

* According to Time Magazine . More scary stats @ Centers for Disease Control and Prevention

Note Mathspigs: Reading statistics requires brains. The probability of you dying from legal execution is ZERO if you have not murdered anyone. The probability of dying from a Vending Machine is almost ZERO if you never go near one. One could, of course, fall of the back off the back of a truck. The probability of dying from heart disease is very low at 12 years of age.

Death by Maths:

Here is the exercise my pretties.

Put these statistics into a bar graph.  The exercise is really looking at GRAPH SCALES because once you put in Heart Disease everything else almost disappears off the graph.

Here is a graph from Chartgo:

Death by lightning strike occurs 1-in-83,930. Now we will convert this to No. Deaths per 100,000.

No. Deaths per 100,00 = 100,000/83,930 = 1.2

Cause of Death US

No. Death per100,000
A. laughing 0.0003
B. roller coaster 0.001
C. vending machine 0.004
D. falling out of bed 0.14
E. texting driving 1.6
F. legal execution 1.7
G. tornado 1.7
H. lightning 1.2
I. snake, bee sting 1.0
J. earthquake

Ball Park Figures or Brad Pitt Does Maths

November 21, 2011


MONEYBALL is a film starring Brad Pitt and  Philip Seymour Hoffman and Jonah HIll on current release in Australia. It is based on the true story of Oakland A’s Baseball team manager, Billy Beane (Pitt), who along with Ivy League Economics graduate and Uber Maths Nerd Peter Brand (Hill) used player stats to save the Oakland A’s baseball team in 2002. 

…..

Not only does Billy Beane have to deal with enormous budget restraints ( Oakland A’s budget was $4o million compared with the Yankee’s $125 million), he showed that the statistics were more effective than experience ie. the  stats BEAT the club selector’s know-how.

.

.

Mathspig, who played softball in Australia – bigger ball, similar rules – saw the film and lerved the maths. Basically, Billy Beane bought up players with one particular skill – holding first base, stealing bases and the like – thus boosting the overall stats for the team. But Mathspig found some of the calculations weird.

This equation is called the Pythagorean Expectation. The wha? Mathspig is sooooo confused.

WHAT’S GOING ON?

Mathpig went searching for an expert opinion and found it at MATHS GOES POP, an awesome blog linking maths with pop culture and written by a mathematics PhD student at UCLA.

Mathspig won’t give a spoiler for the film, but found the maths is BASEBALL MATHS. It’s a formula used for baseball only and named after Pythagoras because it sorta looks – chew gum here and try a Brad Pitt drawl- like the Theorem of that Greek Math Guy. You do not need to use this EQUATION unless, perhaps, you are going to coach the New York Yankees.

Even IF YOU DO COACH THE NEW YORK YANKEES this equation, doesn’t give you that much information.  We will fix ‘runs allowed’. OK. If ‘runs scored’ is high Win is high; it ‘runs scored’ is low Win is low. Um, this means SCORING RUNS is GOOD. Yeah! We knew that without the maths.

If you are interested in the maths, have a look at MONEYBALL MATH on the Math Goes Pop blog otherwise just keep eating your popcorn and enjoy the film.

Maths Makes Money

February 22, 2011

Business partners David Walsh (top, left) and Zeljko Ranogajec(bottom, left) make millions from maths. They employ many mathematicians to constantly calculate probabilities  – OK – odds, and gamble worldwide. But this is BIG time gambling.

From being thrown out of Tasmania’s Wrest Point Casino in the 1980s for counting cards in Blackjack, these partners are now believed to be the BIGGEST GAMBLERS in the world.

According to the HERALD SUN (February 13, 2010)- Mathspig was a columnist with Herald Sun 18 years –

it is believed that Zeljko ‘accounts for 6-8 per cent of Tabcorp’s $10 billion Australian betting turnover or $600-800 million and bets tens of millions more with local bookmakers.

 

But that is just the start. Once the overseas betting turnover of his 24-hour, seven-day-a-week operation is taken into account, his total annual spend globally is believed to be well over $1 billion.

More The Mercury.

If you think this is just gossip, David Walsh has spent over $180 million on his hobby, art collection. He has just opened MONA, the Museum for Old and New Art, involving $100 million worth of exquisite art housed in an $80 million architectural masterpiece outside Hobart, Tasmania. It is a state-of-the-art Art museum. iPods using GPS guide visitors through the museum. It is FREE to the public. More at The Mercury.

Here are some pictures of the museum and the art.

How do you beat the odds?

One way is to buy all possible outcomes in a lottery.

And a last word from Kenny Rogers and the Muppets. You won’t see this again .. a muppet smoking and drinking.

Think about it. Know when to follow through, know when to run … but most of all

know your maths.

4. NO. 26 It’s Your Turn Tonight

October 12, 2010

 Probability.                                          

Independent Events are not RELATED.

Lotto draws are, as with coin flipping, Independent or UNRELATED EVENTS. Newspapers often publish the least drawn numbers prior to a major prize draw.

When on June 5 2008 the Powerball jackpot reached over $50 million, making it the biggest prize ever offered in any Australian lottery game at the time media commentators went crazy. ( See Crazy Lotto Lovers Go Bananas Again!)

The Today show on Ninesmsn website advised ‘The most-drawn Powerball numbers are 26, 22, 5, 39, 24 and 34. The least drawn numbers are 41, 32, 10, 43, 35 and 20.’ This information is worthless. These facts imply that the balls know whose turn it is and then can organise themselves so that those balls drop down the shoot. As if! The draw is random. Any number is possible.

The winning numbers, in drawn order, were: 5, 21, 11, 38 and 2, with the Powerball 33, with the final prize of $58,737,207.41

Poor old 41, 32, 10,43, 35 and 20 will have to wait for another turn!!!!!!!

8. Group Think

October 12, 2010

Statistics

Independent events can cluster.

I’ve seen this phenomena explained on the TV show Numb3rs. Fire a shotgun at a barn wall, draw a circle around a group of bullet holes with chalk and say ‘Wow! We hit the target’. Similarly, if groups of workers at a power plant, say, get a disease, the newspapers immediately blame the workplace. They could be right, but on the other hand, they could be wrong and the real cause of the illness is missed. (See  ABC Cancer Scare example.)

I’ve included the water % chart below to show you how grouping numbers after the event – namely your birth – may NOT reflect the nature of the whole.

eg. ABC abandons cancer scare building (The Age 21st Dec 2006)’

‘The ABC building in the Brisbane suburb of Toowong will be abandoned without knowing the cause of a high incidence of breast cancer cases among women staff members.

A five month investigation by an independent review panel was conducted after 12 women were diagnosed with breast cancer in the past 11 years.’

‘The study showed women who worked at the office reported breast cancer at a rate 11 times higher than the general working community.’

Catalyst ABC TV 11th Oct 2007

Cancer Clusters

‘The site was also tested for carcinogenic pollution and contamination of water supply and air conditioning. Quite simply, no scientific explanation for the cancers was found.’

Radiation levels were tested. Other possible breast cancer causes sited were shift work and the Mouse Mammary Virus.

No causal link has yet been found.
