Game, Set and Math

These pun-studded fables by a popular science writer make complicated mathematical concepts accessible and fun. Twelve essays take a playful approach to mathematics, investigating the topology of a warm blanket, the odds of beating a superior tennis player, and how to distinguish between fact and fallacy.

Fractals

Fractal Geometry is the geometry of the natural world - animal, vegetable and mineral. It's about the broken, wrinkled, wiggly world - the uneven shapes of nature, unlike the idealized forms of Euclidean geometry. We see fractals everywhere; indeed we are fractal! Fractal Geometry is an extension of classical geometry. Using computers, it can make precise models of physical structures - from ferns to galaxies.

Alex's adventures in numberland

Mathematical ideas underpin just about everything in our lives: from geometry of the 50p piece to how probability can help you win in any casino. In search of weird and wonderful mathematical phenomena, the author travels across the globe and meets the world's fastest mental calculators in Germany and a startlingly numerate chimpanzee in Japan.

Prime Obsession

In August 1859, a 32-year-year-old mathematician called Bernhard Riemann hypothesised that there must be a general rule for calculating how many prime numbers there are up to a given point. Proving this theory took over his life, becoming an obsession, just as it has for the hundreds of scientists and mathematicians who have followed him.

God created the integers : the mathematical breakthroughs that changed history

'How the Mind Works' is a fascinating, provocative work exploring the mysteries of human thought and behavior. How do we see in three dimensions? How do we remember names and faces? How is it, indeed, that we ponder the nature of our own consciousness? Why do we fall in love?

The Music of the Primes

In 1859, German mathematician Bernhard Riemann presented a paper to the Berlin Academy that would forever change the history of mathematics. The subject was the mystery of prime numbers. Solving the Riemann Hypothesis could change the way we do business, since prime numbers are the lynchpin for security in banking and e-commerce. It would also have a profound impact on the cutting-edge of science, affecting quantum mechanics, chaos theory, and the future of computing.

The Millennium Problems

In 2000, the Clay Foundation announced a historic competition: whoever could solve any of seven extraordinarily difficult mathematical problems, and have the solution acknowledged as correct by the experts, would receive $1 million in prize money.

Is God a Mathematician?

Is God a Mathematician? investigates why mathematics is as powerful as it is. From ancient times to the present, scientists and philosophers have marveled at how such a seemingly abstract discipline could so perfectly explain the natural world. Is mathematics ultimately invented or discovered? If, as Einstein insisted, mathematics is "a product of human thought that is independent of experience," how can it so accurately describe and even predict the world around us? Physicist and author Mario Livio brilliantly explores mathematical ideas from Pythagoras to the present day as he shows us how intriguing questions and ingenious answers have led to ever deeper insights into our world.

Nothingness : Mathematics starts with an empty set

 

What's inside an empty bag? Nothing – but that's something on which all mathematics is founded... 

What, then, is a number? Mathematical logicians realised that to define the number 2, you need to construct a standard set which intuitively has two members. To define 3, use a standard set with three numbers, and so on. But which standard sets to use? They have to be unique, and their structure should correspond to the process of counting. This was where the empty set came in and solved the whole thing by itself.

Mathematics - Concepts

Key words - analytic, axioms, empiricism, formalism, idealisation, synthetic, theorem, pure mathematics, applied mathematics

Key concepts

Mathematical paradigm - described as the 'science of rigorous proof'

Mathematics is the study of pattern - abstract pattern that places concepts in a systematized relationship to one another, expressed in a symbolic system that we can manipulate using reason alone. 

Nature of mathematical truths - Different views are 1. empirical 2. true by definition 3. rational insights into universal truths

Axioms - Starting points or basic assumptions - four traditional requirements 1. Consistent 2. independent 3. Simple  4. Fruitful

Godel's incompleteness theorem - Kurt Godel proved that it is impossible to prove that a formal mathematical system is free from contradiction.

Goldbach's conjecture - Every even number is the sum of two primes

Proofs and conjectures - A formal system begins with axioms and uses deductive reasoning to prove theorems

Mathematics and certainty -

Discovered or invented - while Platonists believe that mathematical entities are discovered and exist 'out there', formalists argue that they are invented and exist only 'in the mind'

Riemannian geometry - the mathematician Riemann came up with the idea of replacing some of Euclid's axioms with their contraries

Pure and applied mathematics - Mathematics moves both towards the abstractions of the mind, and also towards the connection wiht the world. 

Pure mathematics - researches in pure mathematics, are not concerned with the direct practical applications of their labour. 

Applied mathematics - Mathematics that is used to solve problems in the real world. 

Fermat's last theorem

Mathematics in social context - Alan Bishop, in his studies, identified six forms of recurring mathematical ideas spanning vastly different cultures 1. Counting 2. Locating 3. Measuring 4. Designing 5. Playing 6. Explaining

Mathematics - Questions for reflection

?? Is mathematics invented or discovered? 

?? If mathematics is an abstract intellectual game, then why is it so good at describing the world? 

?? Why should elegance or beauty be relevant to mathematical value?

?? Is mathematics independent of culture?

?? Is there a distinction between truth and certainty in mathematics?

?? What is the relationship between truth and mathematics ?

?? Is mathematical creativity the same as other types of creativity? Is there any difference between beauty in maths and beauty in music? 

?? To what extent do you think people's beliefs about the value of mathematics are determined by their ability in the subject?

?? To what extent do you think the geometric paradigm can be applied to other areas of knowledge?

?? To what extent do you think governments should fund 'useless' research in pure mathematics?
