Physics

David Simmons-Duffin is cur­rently a 3^rd–year Ph.D. stu­dent at Har­vard study­ing the­o­ret­i­cal high energy physics, with a par­tic­u­lar inter­est in the inter­play between string the­ory, extra dimen­sions, and effec­tive field theories.

Music

When not writ­ing about him­self in the 3rd per­son, David dab­bles in musi­cian­ship, hav­ing sung tenor with the Har­vard Col­legium Musicum, Har­vard Uni­ver­sity Choir, The Choir of Clare Col­lege Cam­bridge, Apollo’s Fire, Quire Cleve­land, and most recently Blue Heron. He also enjoys play­ing Baroque vio­lin, and bungling through the Well-Tempered Clavier.

Here is some of his most recent web design work:

Metaphor

If I were a Springer-Verlag Grad­u­ate Text in Math­e­mat­ics, I would be Frank Warner’s Foun­da­tions of Dif­fer­en­tiable Man­i­folds and Lie Groups.

I give a clear, detailed, and care­ful devel­op­ment of the basic facts on man­i­fold the­ory and Lie Groups. I include dif­fer­en­tiable man­i­folds, ten­sors and dif­fer­en­tiable forms. Lie groups and homoge­nous spaces, inte­gra­tion on man­i­folds, and in addi­tion pro­vide a proof of the de Rham the­o­rem via sheaf coho­mol­ogy the­ory, and develop the local the­ory of ellip­tic oper­a­tors cul­mi­nat­ing in a proof of the Hodge the­o­rem. Those inter­ested in any of the diverse areas of math­e­mat­ics requir­ing the notion of a dif­fer­en­tiable man­i­fold will find me extremely useful.
