Man, what a great day for so many! Most of all, the hard working Dr. Leo-Stanley Ndunagum!

Leo-Stanley stands in front of a small crowd after graduation. He wears a green and black graduation gown and sports a Ph.D hat with a gold tassel. He holds his degree and smiles happily.

It is always great to run into former grad students in the wild. Here is hoping that there perminant positions for great people like this in the future!

Hard to beat the north shore.

A rather cold wave breaks on a pebble shore, stirring up the red sand.

It's cool that #FedEx is now doing crumpling experiments too! I hope there is a chance for more substantial collabouration in the future!

Come down to Anaheim for squishy science Sunday!!!

Two children marvel at some granular physics! Some red beads between two clear acrylic sheets show jamming as a scientist slowly opens a gap below the beads. It is somewhat like a two dimensional hourglass. Other scientists look on and many other demos sit on tables.
