The theory of thermodynamics has taught us how to harness the abundant and disordered energy that exists all around us as heat and how to convert it to useful energy in the form of work. For example, we can burn fuel to make the wheels of our cars turn. This understanding helped build the machines of the Industrial Revolution, which forever changed our societies and place in the world. Another revolution is occurring at the nanoscale, where researchers are busy making nanomachines for a host of applications, such as targeted drug delivery and green-energy storage.Smaller is beautiful. Why go big, when you can go small? The bigger one goes, the more entropy one creates. There's no getting around the laws of entropy. But it is possible, with enough creativity, to reduce the amount of disorder created in the multiverse. To read more, click here.
