Future value
A tourist, driving by a Texas ranch, hit and killed a calf that was crossing the road. The driver went to the owner of the calf and explained what had happened. He then asked what the animal was worth.
"Oh, about $200 today," said the rancher. "But in six years, it would have been worth $900. So $900 is what I'm out."
The tourist sat down and wrote out a check and handed it to the farmer.
"Here, is the check for $900," he said. "It's postdated six years from now."

CentigradeIn 1741, the Centigrade temperature scale was devised by astronomer Anders Celsius (1701-44) and incorporated into a Delisle thermometer at Uppsala in Sweden. Celsius divided the fixed-point range of the Fahrenheit scale (the freezing and boiling temperatures of water) into 100 equal divisions, but curiously set the freezing point at 100 and the boiling point at 0. This reverse scaling was changed to match the sense of the other temperature scales after Celsius's death. |
