Failure at High Speed
• Tires are textile-steel- rubber composites.
• Layers of steel wire lying under the tread serve to– stiffen the casing– improve wear and
handing – provide hazard
protection.

President Ronald Reagan
• said in 1985…. “A trillion dollars is so much money that it is hard to grasp the idea.”
• “….. So I want to tell you how to make [a trillion dollars] a little more real.”

President Ronald Reagan
– “If you took a trillion dollars and stacked them on top of each other, the pile would reach halfway to the moon.”

Counting
• The census bureau has recently reported the U.S. population as 281,421,906. – Do you believe this enumeration of
people?• The last time I checked (the U.S.
Treasury website), the public debt was $5,719,452,925,490.54. – Does this to-the-penny accuracy match
its precision?

Counting… all those Chads
• Although most of the vote-counting of the last election concerned what to count, not how to count, the counting process proved unreliable and imprecise.

+,HS-
• Then, recover sulfur as H2S by adding strong acid
• Finally, oxidize H2S in two-step process involving oxygen and sulfur dioxide
