<p>Has mathematics become an experimental science? Yes, according to the most prestigious journal of mathematics - at least that part of maths that involves computer proofs.<p><a href="https://plus.maths.org/content/welcome-maths-lab" target="_blank">read more</a></p>https://plus.maths.org/content/welcome-maths-lab#commentsKepler's conjecturepacking problemsproofMon, 22 Nov 2004 00:00:00 +0000plusadmin2511 at https://plus.maths.org/contentNewton and the kissing problem

<h2>Twelve's Company, Thirteen's a Crowd</h2>
<p>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. Their dispute concerned the "kissing problem." But don't get your hopes up. The term <i>kissing</i> in this context has nothing to do with the gesture of affection: here the verb <i>kiss</i> refers to the game of billiards, where it
signifies two balls that just touch each other.</p><p><a href="https://plus.maths.org/content/newton-and-kissing-problem" target="_blank">read more</a></p>https://plus.maths.org/content/newton-and-kissing-problem#comments23David Gregoryhistory of mathematicsIsaac Newtonkissing problempackingpacking problemsplane geometryWed, 01 Jan 2003 00:00:00 +0000plusadmin2219 at https://plus.maths.org/contentPrize specimens

Last October, two mathematicians won £1m when it was revealed that they were the first to solve the Eternity jigsaw puzzle. It had taken them six months and a generous helping of mathematical analysis. <b>Mark Wainwright</b> meets the pair and finds out how they did it. </div>

<p>Alex Selby and Oliver Riordan, two mathematicians, with the help of a couple of computers, have shared a £1m prize by solving the "Eternity" puzzle. The puzzle was like an enormously difficult jigsaw. There were 209 pieces, all different, but all made from equilateral triangles and half-triangles, as in the example on the left.<p><a href="https://plus.maths.org/content/prize-specimens" target="_blank">read more</a></p>https://plus.maths.org/content/prize-specimens#comments13bayes theoremcomputer searcheternity gamegrid problemspacking problemsplane geometryprobabilitytilingMon, 01 Jan 2001 00:00:00 +0000plusadmin2175 at https://plus.maths.org/contentMathematical mysteries: Kepler's conjecture
