A Mathematical Framework for the Universe

August31

By the early 1900s, it was clear that Newtonian mechanics was in trouble. It could not explain how objects moved near the speed of light, leading to Einstein’s special theory of relativity. Newton’s theory of universal gravitation was in similarly hot water, as it could not explain the motion of Mercury around the Sun. Concepts […]

The Mathematician from Madras, India

July16

My first impression of Madras was a modern, Indian city bustling with activity; a diverse gateway to the south and a hot and dusty place preparing for the rainy monsoon season. It as a place of old cars, farm carts carrying produce, and people busy in the pursuit of commerce. Woman were down at the […]

Girolamo Cardano

December21

‘Girolamo’ is not a very popular name for anyone, but Girolamo Cardano was a famous mathematician who lived from 1501-1576. He was a doctor and the author of 131 books. He was also a compulsive gambler. It was this gambling habit that led him to the first mathematical analysis of probability. He realised he could win […]

Did Einstein Really Flunk at Math?

May21

In this picture, taken in 1934, a rather nervous-looking Albert Einstein gives a lecture to the American Association for the Advancement of Science in Pittsburgh. But, rumour has it that he failed in his early math exams. Scientists announced in 2016 that they had detected gravitational waves from the merging of two black holes in […]

Math Prof wakes early to view black hole image

April11

Astronomers have captured the first image of a black hole, proving the University of Canterbury’s distinguished Professor Roy Kerr’s 56-year-old theory correct. Kerr said he set his alarm for 1am to see this exciting event. “The event horizon telescope photo is just the beginning of a new phase in the understanding of our universe. “The […]

5 Brilliant Mathematicians who impacted the modern world

January17

“Mathematics – you either love or hate it, right? Those who hate math might still have nightmares of showing up for a high school math test unprepared, even years after graduation. Math is, by nature, an abstract subject, and it can be hard to wrap your head around it if you don’t have a good […]

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)?]
