When particle physicists try to model experiments, they confront an impossible calculation — an infinitely long equation that lies beyond the reach of modern mathematics. Fortunately, they can ...

The calculation -- named the Cottrell equation for chemist Frederick Gardner ... control the reaction -- which is what we want in the long term," said lead author Rileigh Casebolt DiDomenico ...

His tool? A 1980s-era computer program called FORM. Particle physicists use some of the longest equations in all of science. To look for signs of new elementary particles in collisions at the ...
