Beam Reach

This morning, Jason and I showed a number of our research interests and interspersed these with various demonstrations and class activities. It was fun to watch you students sitting with your heads down on your desks and raising your hand when I dropped the audio frequency going into our speakers down below about 19 kHz and putting your hands back down when the frequency went up a bit. All this was far, far above anything I could hear. I know you all can hear very, very well. This bodes well for the course!

I hope that Dr. Stern (our expected evening speaker on Minke whales) got back safely from the sea after his vessels motor failed.

See you tomorrow — let’s cool off!
