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 […]

Artificial and Imperfect Intelligence

August24

(from CNN): Artificial intelligence often induces fear, awe or some panicked combination of both for its impressive ability to generate unique human-like text in seconds. But its implications for cheating in the classroom — and its sometimes comically wrong answers to basic questions — have left some in academia discouraging its use in school or […]

How many dimensions you may ask?

March3

Over the past century, the quest to describe the geometry of space has become a major project in theoretical physics, with experts from Albert Einstein onwards attempting to explain all the fundamental forces of nature as byproducts of the shape of space itself. While on the local level we are trained to think of space […]

Time for Time Travel?

September29

Hold onto your flux capacitors! A young University of Queensland student may never be late for class again – or even early for that matter. He says he has found a way to “square the numbers” and prove that “paradox-free” time travel is theoretically possible in our universe. From Back To The Future to Terminator, stories […]

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 […]

Back to the Future Pt2

December16

Ben Tippett, a mathematics and physics instructor at UBC’s Okanagan campus, recently published a study about the feasibility of time travel. Tippett, whose field of expertise is Einstein’s theory of general relativity, studies black holes and science fiction when he’s not teaching. Using math and physics, he has created a formula that describes a method […]

We can’t go back in time, can we?

April3

Hey, with Daylight Saving coming into effect, we lost an hour last night, but where did it go? I was taught that, in order to go back in time, you would need to travel faster than the speed of light (thanks Einstein). But, the physicists tell us, this is impossible, so we can’t have lost […]

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)?]
