Week 9 (Mar 13 and Mary 15): Chapter 5. (and starting on 6) Ode to the Ossicles (Allison and Susan Sekuler)Every creature, live or fossicles, cannot hear without their ossicles. Except, as hard as they may wish, there are no ossicles in fish. You might think this quite unfair, but fish do not live in air, so they simply do not care. Why? Air flows through the middle ear 'til a cochlear impasse does appear. From air to liquid, sounds abate, hence the ossicles must vibrate. From the ear drum vibrations play, setting the ossicles on their way. Hammer moves anvil moves stirrup and so sounds amplify at the oval window. Now sound increased many-fold enters the cochlea strong and bold So that you may hear this story told.Check out some of your classmates' responses to last Tuesday's "tell me some physics you've thought about outside of class".

To many, he was the greatest American musician of the 20th century. Louis Armstrong (watch here and here) started out playing the cornet, but switched to the larger trumpet around 1930. His Hot Five and Hot Seven tracks (1926-28) are often cited as the greatest jazz recordings ever made. Besides playing the trumpet, Armstrong was a highly influential and entertaining vocalist. He is credited with inventing the scat singing style (listen to Heebie Jeebies). At age 63, Armstrong knocked the Beatles off the top of the Billboard chart with Hello, Dolly. |
