The Paradox of the Mathematical Cone
Simon showed me an interesting paradox that’s difficult to wrap my mind around. If you slice a cone (at a random height), the section is a circle. The chopped-off part … Continue reading The Paradox of the Mathematical Cone
The game of Loop
Simon has learned about a beautiful new game from Alex Bellos on Numberphile. The game is called Loop and resembles pool. The pictures below illustrate the layout on an elliptical … Continue reading The game of Loop
Rubik’s Cube Moves
Simon is getting faster and faster with the cube. Order a speed cube for his upcoming birthday? So much for “poor fine motor skills”.
Ramanujan-converging
Today Simon learned that it was Euler who first came up with the idea that the infinite sum 1 + 2 + 3 + 4 +… converges to -1/12. Simon … Continue reading Ramanujan-converging
Trinity Hall Prime Number
Simon saw this pattern in a Numberphile video featuring Tadashi Tokieda and recreated it in Excel, adding colours. There are 30 columns and 45 rows of digits in this picture, … Continue reading Trinity Hall Prime Number
Vectary.com
Simon has discovered a great new graphing tool: Vectary.com! “Finally I have found something topological,” Simon says. “There is a branch in math called topology. It’s about deforming things. I … Continue reading Vectary.com
Math on the Beach
Simon doing math everywhere. And he showed me this beautiful trick of two rows adding up to equal numbers and their squares adding up to equal numbers. And the two … Continue reading Math on the Beach
A Pythagorean triple
Proving a Pythagorean triple. 3Blue1Brown did it in another way, using i.
Knots and Links
Simon explains: The Knot Atlas is a complete catalogue of all the possible knots and links and links with 3 or fewer components and 11 or fewer crossings. The number … Continue reading Knots and Links
Tricks with paperclips and Knot Theory
Simon is pretty obsessed with Knot Theory at the moment (a mathematical theory that is widely used in advanced biology and chemistry, for example in handling tangled DNA). He also … Continue reading Tricks with paperclips and Knot Theory
