A Department Store

A really huge muscular guy with a bad stutter goes to a counter in a department store and asks, "W-w-w-where`s the m-m-m-men`s dep-p-p-partment?"
The clerk behind the counter just looks at him and says nothing.
The man repeats himself: "W-w-w-where`s the m-m-m-men`s dep-p-p-partment?" Again, the clerk doesn`t answer him.
The guy asks several more times: "W-w-w-where`s the m-m-m-men`s dep-p-p-partment?"
And the clerk just seems to ignore him. Finally, the guy is angry and storms off.
The customer who was waiting in line behind the guy asks the clerk, "why wouldn`t you answer that guy's question?"
The clerk answers, "D-d-d-do you th-th-th-think I w-w-w-want to get b-b-b-beat up?!!"

Alexander Bache

Died 17 Feb 1867 at age 60 (born 19 Jul 1806).Alexander Dallas Bache was an American physicist who was Ben Franklin's great grandson and trained at West Point. Bache became the second Superintendent of the Coast Survey (1844-65). He made an ingenious estimate of ocean depth (1856) by studying records of a tidal wave that had taken 12 hours to cross the Pacific. Knowing that wave speeds depend on depth, he calculated a 2.2- mile average depth for the Pacific (which is within 15% of the presently accepted value). As President of the National Academy of Sciences, Bache secured greater government involvement in science. Through the Franklin Institute he instituted boiler tests to promote safety for steamboats.
