This year's #AbelPrize goes to Argentinian mathematician #LuisCaffarelli for a lifetime of work in #RegularityTheory.

The partial differential equations I worked with as a space physicist did not lend themselves easily to numerical solutions in upper atmosphere models. Regularity, or smoothness, was near impossible to achieve in model output, and the mathematical theory was way above my level of comprehension at the time.

Congratulations to Prof Caffarelli!
