Pi Day Revisited

December1

Yes, today is NOT Pi Day – well, not officially. After all, every day is Pi Day since every day Pi is being used to solve both simple and complex problems, many times without anyone realizing it. Yes, Pi might just have to be the most exciting irrational number on the planet! What do we mean […]

If I learn Pi to 1000 places will I be a better mathematician?

February16

This post asks an interesting question. So, as a high school student, I go to the trouble (and it would be some trouble) to learn the value of Pi to 1000 decimal places. Will that make me a better mathematician? NO, according to recent research on how we learn. Check out this article on this […]

Pi Day, Oz Style

March14

Yes, we were ahead of our lagging mathematicians in other classrooms today – with an early Pi DAY. March 14 (3.14) is a day ahead of our American counterparts and staff were delighted to receive small jam and lemon tarts to celebrate this auspicious day in the Mathematics calendar! Would love to see photos from […]

Mathematics and the art of string theory

March9

The artist Louisa Bufardeci has long been fascinated by the rich resources of scientific theory. String theory is an area of Physics that aims to describe all the parts of the universe, and how they behave, in one master mathematical equation. It has led physicists to suggest that the smallest element of matter, from which […]

Pi Day is getting closer!

March3

Yes, we are again (see the last Pi Post) heading towards Pi Day (March 14 or 3/14 in the USA). Of course, in Australia and New Zealand we are able to celebrate a day earlier (on 14/03) than our North American mathematicians! We wonder whether Google will produce a unique Pi Day logo?

Life of Pi – Mathematics at the Movies

January24

Life of Pi is a movie by Ang Lee about the stories of a boy, Piscine, who suffered verbal abuse in school because his name was often taken to be “Pissing”.  To move beyond this, he makes a huge effort to become known as Pi by going up to the blackboard in every class he attends […]

Mind-Boggling Math Fact #1

January20

The sonnet “Like a Shakespearean sonnet that captures the very essence of love, or a painting that brings out the beauty of the human form that is far more than just skin deep, Euler’s Equation reaches down into the very depths of existence.” Stanford mathematician Keith Devlin wrote these words about this equation in a 2002 […]

Amazing Brain Man

October9

Daniel Tammet was bullied at school and also suffers from autism, etc. Yet, he has been gifted with an amazing ability to manipulate numbers. Check out this video link for an insight into Daniel’s rather different way of thinking mathematically.

Largest number between o and 1 million which does not contain the ‘n’ is 88

 

Rotation SAT Problem: Answer: 4 (see: https://www.youtube.com/watch?v=FUHkTs-Ipfg)

 

Which number has its letters in alphabetical order? Answer: F O R T Y

Hidden Rabbit? Clue: check the trees

How long for the stadium to fill? 45 minutes.

Where are you? the North Pole

Prize Object Puzzle: If Sue does not know where the prize is in the first question, it can’t be under the square. She must have been told it is under another shape. Apply this same logic to Colin. It is then obvious that the prize cannot be under a yellow object. That helps Sue eliminate her yellow shapes. Got the idea?

Algebra Puzzle: Answer = 1

Popular Math Problems Answers: 1, 1

Number of tabs? According to Lifehacker, the ideal number of tabs you should have open is nine. Yes, a single digit. To some, this is like playing a piano and only using a fraction of the notes!

Worst Graph? Where to start. What a visual mess and even some of the lines merge and are impossible to follow. A graph is a visual display of data, with the goal to identify trends or patterns. This is a spider’s web of information which fails to show a clear pattern at all. Solution? Well, different colors would help, or why not group in two or three graphs where trends are similar?

Number of different nets to make a cube is eleven – see this link

Homework Puzzle; The total value of the counters is 486, so halve this to get 243. Now, arrange the counters to equal this amount twice.

The graph on the left (Coronavirus) is for a time period of 30 days, while the one on the right (SARS) is for 8 months! Very poor graphical comparison and hardly relevant, unless it is attempting to downplay the seriousness of the coronavirus?

10 x 9 x 8 + (7 + 6) x 5 x 4 x (3 + 2) x 1 = 2020

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
