history of mathematics
Daniel Bernoulli (1700-1782) discovered the relationship between the density of a fluid in a pipe, the speed it is travelling in the pipe and the pressure exerted by the fluid against the walls of the pipe. This is the story of what happened.
Bill Casselman writes about the intriguing amateur mathematician Henry Perigal, who took his elegant proof of Pythagoras' Theorem literally to his grave - by having it carved on his tombstone.
In 1694, a famous discussion between two of the leading scientists of the day - Isaac Newton and David Gregory - took place on the campus of Cambridge University. The discussion concerned the kissing problem, but it was to be another 260 years before the problem was finally solved.
100 years after the birth of Paul Dirac, mathematicians and physicists gather to celebrate his beautiful work.
Fibonacci, famous for the Fibonacci sequence, also introduced the decimal system into Europe.
When Kurt Gödel published his incompleteness theorem in 1931, the mathematical community was stunned: using maths he had proved that there are limits to what maths can prove. This put an end to the hope that all of maths could one day be unified in one elegant theory and had very real implications for computer science. John W Dawson describes Gödel's brilliant work and troubled life.
Great minds spark controversy. This is something you'd expect to hear about a great philosopher or artist, but not about a mathematician. Get ready to bin your stereotypes as Rebecca Morris describes some controversial ideas of the great mathematician David Hilbert.
Being good at mental arithmetic isn't going to gain you much street cred these days. But, as Owen Daniel explains, not so long ago it was a sure route to fame and fortune — even if you were a horse.
How to count without counting
Leonhard Euler was one of the most prolific mathematicians of all time. This year marks the 300th anniversary of his birth. Robin Wilson starts off a four part series on Euler with a look at his life and work.
If you thought you knew what geometry is all about, then this issue of Plus may change your mind. We explore a strange point-less geometry of spacetime, find out about hyperbolic geometry's amazing fractals, celebrate a geometric formula named after Leonhard Euler, the most prolific mathematician of all time, and try to calculate pi. This issue also contains the first ever Plus teacher package and, to celebrate our tenth birthday, continues our series on the history of Plus.
Johannes Kepler (1571-1630) is now chiefly remembered as a mathematical astronomer who discovered three laws that describe the motion of the planets. J.V. Field continues our series on the origins of proof with an examination of Kepler's astronomy.
What's the risk of climate change or passive smoking? Why do penguins rotate their eggs? What makes mathematicians reach out for god? And how did we evolve the maths behind these questions? Find some answers in this political, psychological, philosophical and physical issue of Plus, and do some real sums with our interactive checker board.
