For 145 years, Popular Science has pointed readers to the wonders of science, technology, and the future.

“It can be dangerous to believe things just because you want them to be true. You can get tricked if you don't question yourself and others, especially people in a position of authority.” How Carl Sagan described death to his young daughter: pops.ci/sagan

Whoaaaa here’s what it’s like to fly inside Hurricane Florence... 

Today, we're honoring the late Carl Sagan—who would have been 83 today. And we can't think of anyone who inspired so many people to love science and the universe. For our September 1972 issue, we sat down for an interview with Carl Sagan about our rusty neighbor, Mars. For several months before our interview, @nasa‘s Mariner 9 spaceprobe had been sending back thousands of photographs of the planet's surface which raised more questions than they answered. And the man who reminded us we are all made of starstuff, dissected some of Mars' mysteries in his trademark educational and awe-inspiring way. If only Professor Sagan could see what we're doing on Mars now!

On this day in 1867—150 years ago—Marie Curie was born! The pioneering chemist, physicist, and first woman to win the Nobel Prize was featured prominently in our April 1924 story, Science Sees, Hears, Counts Atoms, and by that point, Curie had already won two Nobel prizes for her studies on radioactivity and for her discovery of radium polonium. As if those accomplishments weren’t significant enough, Curie also impressed us with her prototype for a machine that would permit researchers to visualize and hear atoms. Equipped with a radio loudspeaker, the machine would amplify the movements of helium atoms shot from polonium. Audiences could then use the subsequent ticking noise to count the atoms as they were dispelled. Here’s to Marie Curie, quite possibly the greatest scientist who has ever lived.
