The video of my Dibner Library Lecture in December is now available online, here.
Although it was dark in the room, and I had to wear the microphone power-pack on the back of my collar, you can see and hear me well. The audio/visual folks did a great job!
I really enjoyed giving this talk—it was such an engaged audience! Thanks again to the Smithsonian Institution for the invitation, and to everyone who braved the torrential rain to attend.
