Today, poetry and science are often considered to be mutually exclusive career paths. But that wasn’t always the case. The mathematician A da Lovelace and the physicist James Clerk Mahwah were both accomplished poets. The poet John Keats was a licensed surgeon. Combining the two practices fell out of favor in the 1800s. But translating research into lyrics, haiku, and other poetic forms is resurging (再现) among scientists as they look for alternative ways to inspire others with their findings.
