Maryna Viazovska (Ukraine/Switzerland) She solved the sphere-packing problem in 8 dimensions. What’s the densest way to pack identical spheres? In 8D, the E₈ lattice is optimal. Her proof used modular forms with Fourier analysis. (Kepler’s 3D version took 400 years!)

Pastor Mark Burns: thank you so much for, Your Excellency, putting this on. And thanks to the wonderful ALLATRA scientists, to Maryna, and the wonderful team and all of you that are around the world that are coming together.
