Lost it!
A guy and a girl are lying in a dorm-room bed after just having sex.
The guy lies on his side of the bed and rests.
The girl rolls to her side of the bed and says to herself, "I finally did it! I'm no longer a virgin."
The guy overhears her talking to herself and asks, "Are you saying you lost your virginity to me?"
"Well," the girl explains, "I always wanted to wait until I was with the man I love to lose my virginity."
Astounded, the guy replies, "So you really love me?"
"Oh God no!" the girl says. "I just got sick of waiting."

Konel alloyIn 1929, the discovery of Konel, a new metal alloy was announced by Erwin Foster Lowry, of the Westinghouse Electric and Mfg. Co. research department of Pittsburgh, Pennsylvania. The name reflects the cobalt (ko-) and nickel (-kel) in the alloy. An interesting characteristic is that konel grows stronger at high temperatures, whereas other metal becomes weaker with heat. For example, at 600ºC, konel has twice the tensile strength of chrome nickel steel. When used in oxide-coated filaments for radio vacuum tubes (replacing expensive platinum), konel gives much better electron emission. Other uses include turbine blades; also car engine valve stems and pistons. Its composition is 73% Ni; 17.5% Co; 6.5% Fe; 2.5% Ti; 0.2% Mn.« |
