When French engineer Sadi Carnot calculated the maximum efficiency of a heat engine in 1824, he had no idea what heat was. In those days, physicists thought heat was a fluid called caloric. But Carnot ...
Heat engines are thermodynamic physical systems that convert heat energy into mechanical work by exploiting a temperature difference between a high-temperature heat source and a low-temperature heat ...
A VERY useful account is given in this book, from an engineering point of view, of the application of thermodynamics to the theory of the steam engine, mechanical refrigeration, steam nozzles, steam ...
A satellite image shows the huge snowstorm that blanketed the northeastern United States this week. The blizzard was an example of how storms are getting less common but more intense.
Scientists are working on a heat engine that consists of just a single ion. Such a nano-heat engine could be far more efficient than, for example, a car engine or a coal-fired power plant. Scientists ...
Physicists have created a device that has experimentally exceeded the conventional second law of thermodynamics. The device is an information engine, which converts information into work, and it is ...
As with many branches of physics and engineering, a common point of debate and research is: Under what conditions do the classical laws and theories of physics break down and quantum theories are ...
