- Breaking the sound barrier
-
- U.S. Navy Ensign John Gay captured one of the best images ever taken of a sonic boom (the breaking of the sound barrier) in 1999. He snapped a photo of an F/A-18 Hornet on a humid day from the weather deck of the USS Constellation in the Pacific Ocean (see image). Because aircraft wings generate both low-pressure regions (because of lift) and amplified low-pressure disturbances, large low-pressure regions exist near the aircraft, especially under sonic flight conditions. The lowered pressure condenses the water in the air, creating a vapor cloud. As the jet produces these pressure waves and propagates ahead of them, the regions of lower pressure are usually strongest behind the nose of the jet, on the wings and body. As the aircraft continues to speed up, the vapor cloud will appear farther toward the rear of the aircraft. Then, just as the aircraft bursts through the sound barrier, the air is locally disturbed by the resulting shock wave and the condensation/vapor cloud disappears. Ensign Gay snapped his photo at the moment he heard the boom, just before the cloud vanished. Thus, it literally appears as if the F-18 is pushing through the sound barrier at the instant the photo was taken.

- ∆ vs. “lil d”
-
- In order to understand derivatives, you have to realize that there is no practical difference between 3.000000000000000 seconds and 3.000000000000001 seconds.
-
- we call this the limit as ∆t –> 0.

- NOT ON TEST 3 — We will discuss this Wednesday (10/29) if we have timeNow here’s where things get funky. Let’s unroll those rings and line them up. What happens? We get a bunch of lines, making a jagged triangle. But if we take thinner rings, that triangle becomes less jagged. Taking small segments for more accuracy is general tenet of calculus. One side has the smallest ring (0) and the other side has the largest ring (2πr ). We have rings going from radius 0 to up to “r”. For each possible radius (0 to r), we just place the unrolled ring at that location. The total area of the “ring triangle” = 1 2base x height = 1/2 r (2πr ) = π r^2, which is the formula for area! Yowza! The combined area of the rings = the area of the triangle = area of circle! This was a quick example, but did you catch the key idea? We took a disc, split it up, and put the segments together in a different way. Calculus showed us that a disc and ring are intimately related: a disc is really just a bunch of rings. This is a recurring theme in calculus: Big things are made from little things . . . and sometimes the little things are easier to work with.
