Mathematics – a Question of Faith, but which One?

October22

In this powerful interview, Dr. Anthony Bosman, PhD in Mathematics, reveals why the language of math woven into the fabric of the cosmos points unmistakably to intelligent design. From physics to probability, from equations to evidence, this conversation explores how mathematics itself testifies to the existence of God…

John Lennox, Professor of Mathematics at Oxford University, shares his view on this very question in his delivery here at UCLA.

Data in Conflict and a Genius Mathematician

October2

In this remarkable post, a Mathematician interprets data in a way that stuns others. It’s a long, but fascinating insight into the way Statistics can be applied during conflict to save lives.

It Takes 10,000 Hours

July8

In a study involving Japanese and American first graders, kids were given a difficult puzzle to solve while researchers measured how long they would try before giving up. On average, the American children lasted 9.47 minutes. The Japanese children lasted 13.93 minutes. That is a 47 per cent difference. Want to guess who scores higher on standardised maths tests? Success in any endeavour is a by-product of trying harder and trying longer…There are no shortcuts. It doesn’t matter whether it’s athletics or academics, music, or math. Study after study has shown that it takes about ten years or ten thousand hours to become great at anything. You need to work hard and work long. In the words of Malcolm Gladwell, “Ten thousand hours is the magic number of greatness.”

Brain Map Blows Your Mind

April16

Fromm CNN: Using a speck of mouse brain matter the size of a grain of sand, scientists have created the first precise, three-dimensional map of a mammal’s brain. Check this out…

The map details the form, function and activity of 84,000 neurons, branched structures that fire off messages down a long arm, called an axon, and then through more than 500 million synapses, as well as 200,000 brain cells. The tiny piece of tissue contained 3.4 miles (5.4 kilometers) of neuronal wiring — nearly one and a half times the length of New York City’s Central Park.

The work is the culmination of almost a decade of research by 150 scientists at 22 institutions led by the Allen Institute for Brain Science, the Baylor College of Medicine and Princeton University.

“One byproduct of this whole project shows us just how incredibly beautiful the brain is,” said Dr. Forrest Collman, associate director of data and technology at the Allen Institute, in a video shared by the organization.

“Just looking at these neurons shows you their detail and scale in a way that makes you appreciate the brain with a sense of awe in the way that when you look up, you know, say, at a picture of a galaxy far, far away,” he added.

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)?]
