Tyson is right: we wouldn’t have all the things we enjoy today, from Fords to iPhones to the interwebs, without science.

That requires respecting the foundations that gave us science, math and the tech we rely upon today. And it means respecting scientists. Because they are under attack on a number of fronts, including Soviet-style misinformation and propaganda campaigns.

This is why people are marching for science today.

Scientists around the world, I salute you and the work you do.

Bonus: my favorite marching sign.
