Illustrated by Emma Munger What have the world’s sexiest people ever really done for the world? We should be crushing big-time on the beautiful brains of the people who make a difference. Elon Musk, swoonworthy inventor who spends his billions developing sustainable energy and space exploration. Ruth Bader Ginsburg, (gavel-) bangin’ babe of the US Supreme Court who has spent her life fighting for women’s rights. David Attenborough, the foxy zoologist-turned-broadcaster who has inspired generations to care about the natural world. And not to mention Ada Lovelace and her white-hot drop-dead machine algorithm-inventing intellect. These dreamboats are the real pin-ups, the poster people for brilliance, bravery, and giving a damn.
