The Physicist Who Discovered Cosmic Rays

[@fredsalter1915]

2:04 Wow! Dr. Hess had a lot of students!

[@captnholz]

Thank you for your videos, I love learning about the history of scientific discoveries.

No fluff, just info, love this style of science communication!

Short and to the point. Sweet.

There are many beautiful graphs, historic photos and paintings. The storytelling is interesting, clear and compact. It also helps that you have a pleasant voice and manner of speaking. I am subscribing 👍

I just had a déja-vu. One of my students gave a presentation on cosmic rays and Hess today :-)

I know. Right? I have a Geiger Counter. Not only the height above the Earth's surface via balloon flights (I will have to take their words for that), but during the day too. I've found by actual experiments with my meter. So, Solar Wind, then. I made a small low power "atom smasher," the output of which I checked out with my meter. For those that might be interested: 1, 1 million electron volt is about the energy in 1/2 of one photon of your average photon for the color green. Think in terms of amps and Ohm's Law, where Voltage = current * resistance, per second. Boggle. Who knew? Makes sense, the energy needed for all that yummy photosynthesis going on....

So it wasn't Dr Cosmic? Bummer.
