The blank pages at the end of books aren't there to take notes. It's rather the result of technical constraints assembling the pages. A typical first chapter will start using an uneven number (i.e., 1). Since books are printed in multiples such as 8, 12, 16 etc., if a subsequent chapter starts with an even number, for technical reasons blank pages are accumulated at the end.
The name of the sport ''Tennis'' gets its origin in the ''Game Of The Palm''. Once the game commenced, the player had to say ''Tenez!'' (Hold!). The Anglo-Saxons understood Tennis. The reason for this confusion comes from the fact that 17th century French the word ''Tenez'' was pronounced ''Tenets! ", using an ''S'' at the end, which does indeed sound like tennis.
Water does not always boil at the usual 212 degrees Fahrenheit (100 degrees). It depends primarily on atmospheric pressure and related conditions. Therefore, high in the mountains, water will boil at an inferior temperature (and more quickly) as the pressure is lower, contrary to the water in a kettle.
The CD has a capacity of 74 minutes, because during the design the engineers decided that its ultimate capacity should be able to encompass Beethoven's Symphony No. 9 in its long version. To accomplish this criterion, they had to choose a 12 centimeter 16-bit 44.1kHz disc format.
