Heat waves: Five reasons why Victorian houses are cooler than modern buildings

More than 4 million homes were built in the U.K. during the Victorian era. Victorian homes were constructed long before the complex computer models used today to design buildings were invented. Yet these homes, built more ...

Fidget-controlled robots show the power of metastability

Fidget poppers are an example of "bistability," as the popped circles rest in one of two stable states. Purdue University researchers have taken this idea to its extreme, building robots that can be preprogrammed and controlled ...
