Heat' and temperature, although different, are intimately related. [...] For example, suppose you added equal amounts of ' heat to equal masses of iron and aluminum. How do you think their temperatures would change?if the temperature of the iron increased by 100 C°, the corresponding temperature change in the aluminum would be only 48 C°.

The researchers found that the original texts spanned a variety of entropy values in different languages, reflecting differences in grammar and structure.
But strangely, the difference in entropy between the original, ordered text and the randomly scrambled text was constant across languages. This difference is a way to measure the amount of information encoded in word order, Montemurro says. The amount of information lost when they scrambled the text was about 3.5 bits per word.
