A team of physicists and mathematicians at the Institute for Basic Science's Center for Soft and Living Matter, in South Korea, working with a colleague from the University of Geneva, has developed an algorithm that can be used to find the shape of an object to cause it to roll down a ramp following a desired path.
It classifies as a basic math result, I’d think. Math is all interconnected, so you’d expect everything to have an economic impact eventually by force of statistics. If there was a part of math that stubbornly refused to go anywhere near applications that would itself be interesting.
