Mad Scientist Stereotype Outdated
Do people still imagine a physicist as a bearded man in glasses or has the image of the mad scientist changed The Institute of Physics set out to find out whether the stereotype of a physics "boffin" (科学家) still exists by conducting a survey on shoppers in London. The people were asked to identify the physicist from a photograph of a line-up of possible suspects. 98 percent of those asked got it wrong.

The stereotype of the absent-minded scientist has lasted a long time because the media and Hollywood help promote the image of men in white lab coats with glasses sitting
