Correction to what I say at 15 mins 57 seconds: It's should be 3 orders of magnitude, not 30. You'd think that technology and science make a good team, and most often that's true, but every once in a while they get into a big fight. One such case is the 5th generation of wireless networks, 5G for short, that's become a big headache for meteorologist because millimeter waves interfere with the weather forecast. On that occasion I also tell you about a recent review on the health effects of 5G and what 6G may bring. 💌 Sign up for my weekly science newsletter.
