Isotherm, in geography, a line drawn on a map connecting places that have the same average temperature for a given period of time. For example, an isotherm running through New York City, St. Louis, and Seattle would indicate that these cities, as well as any others along the line, all had the same average temperature for a specified period. Isotherms are useful in compiling and showing climate information. For example, for general farming, an average temperature of at least 60 F. (16 C.) is necessary during the warmest months. A map marked with an isotherm of 60 F. for the months of July and August would show the northern limit of the area where the temperature would permit general farming.
Modern science allows us to break atoms down into tiny components. But can scientists use their mighty machines to recreate the foundation of the universe?
He's ventured to the abyss of black holes, wagered on the information paradox and floated around in zero gravity. Meet the man, the legend, the super scientist: Stephen Hawking.
