Maths, magic and mystery Chris Budd
Who likes magic? We like magic because Its mysterious Its dramatic It has an element of surprise It has glamour and excitement! This seems a bit different from a logical and rational subject like maths!
Maths is a highly creative subject full of mystery and surprises But an even more mysterious fact is … Most people dont realise this!
Maths is the study of abstract objects and the patterns that link them together Links are called theorems They are often deeply amazing, mysterious,beautiful and very, very useful!
Some amazing theorems a b c Pythagoras Gregory Euler
Unfortunately, not everyone appreciates their mystery and beauty But … most people like magic, art and storytelling! Some people are even scared of maths!
By linking maths to magic, art and storytelling we can unlock some of its mysteries Theorems can lead to some great magic tricks!!!
Some Mathematical Magic Tricks Clocks Cards Mind reading
Some mind reading Take a 4 digit number x eg. 7563 Scramble the digits to give y eg. 3567 Subtract y from x (or vice versa) 3996 Cross out a non-zero digits and tell me the others eg. 396
Digital root of a number = sum of digits x and y have the same digital root Theorem The difference z between two numbers with the same digital root, has a digital root which is always a multiple of 9 Theorem The difference z between two numbers with the same digital root, has a digital root which is always a multiple of 9
Maths in Celtic and African Art Celtic African
How to draw simple Celtic Knots Start with a grid (5, 4) grid
(2,2) 2 (3,2) 1 (5,3) 1 (4,4) 4 How many pieces of string are needed?
Simple Celtic Knots are very similar to plaited mat sona drawings Sona … African sand patterns (3,4) (2,4)
We can also produce more advanced African sona … Chased Chicken designLions Stomach design
