Artist of Geometric Proportions

March20

Rafael Araujo‘s illustrations are bewilderingly complex – so complex that you might assume the artist uses a computer to render the exacting angles and three-dimensional illusions. Araujo doesn’t use modern technology to create his intricately drawn Calculations series – unless, of course, you count a ruler and protractor. In Araujo’s work, butterflies take flight amidst […]

Art attracts Mathematicians in Italy

February13

The amazingly beautiful and accessible Duomo in Milan, built over some 4 centuries, was such a compelling Gothic building that it attracted many talented Mathematicians and Scientists – who wanted to study and share in the beauty and power of the Duomo. As the cathedral’s architecture became the powerhouse of intellectual culture in northern Italy, […]

The Art of Rectangular Pyramids

January15

Ah…The Louvre – perhaps the world’s most famous museum and an iconic, classical building which is noted for its modernistic entry which uses pyramids to contrast its surroundings. (H3 was taken aback by the beauty of this entry and the way in which it differed so much to the style of the French buildings and […]

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 […]

Mathematics and Art – II

April4

In this piece by Fernand Leger, called “Composition sur fond bleu” or “Compositon on blue background” we can clearly see his French roots grounded in an appreciation of Cubism. Leger first studied architecture but after his war time experience (WWII) he became obsessed with the beauty of precision engineering. You can see machinery quite clearly […]

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)?]
