No single individual may be more synonymous with the term “genius” than Albert Einstein. Born in Germany, but forced to flee Europe during the Nazi occupation, Einstein ended up becoming one of the greatest physicists of all time. Now, a letter he wrote in 1949 has been discovered, revealing some of Einstein’s thoughts on various topics. In the letter, Einstein discusses possible connections between physics, biology, and wildlife. In other words, can scientists make new breakthroughs by studying how animals such as birds and bees move and fly around? This letter may date back over 70 years, but modern physicists are still debating that question. Moreover, recent discoveries pertaining to migratory birds actually appear to corroborate what Einstein wrote all those years ago. In short, Einstein was correct in theorizing that animals can provide us with some clues about how physics works. “Seven decades after Einstein proposed new physics might come from animal sensory perception, we’re seeing discoveries that push our understanding about navigation and the fundamental principles of physics,” says RMIT University Associate Professor Adrian Dyer in a release.
