I once told a friend of mine that I'm agnostic about quantum physics because we can't see it or feel it with our own senses and we have to use elaborate rituals conducted by a special class of people who say "we have the esoteric knowledge to interpret all of this" and that that's not that different than religious belief.
He got mad at me.
@MLE_online I think the standard comment would be more like 'gps doesn't work without it's
@MLE_online @furicle butbutbut :D
Unlike trying to take god away and seeing whether the sun still rises, we can test and every-day experience quantum physics!
Like, do solar cells work? OK, photovoltaic effect; that's quantum physics! Modify the material the solar cells are made of, and it stops working the same. You can test that!
Do LEDs work? yep! Can you test that their current rises exp.ally with voltage? Yep! Do blue LEDs have a higher forward voltage than red ones? Yes! bandgap! QP!
@MLE_online @furicle while I agree it's hard to look inside what really makes an LED "tick" in an everyday scenario, how's that different from say, friction and lubricants in an engine? Microbes in the air? Aerodynamic lift making planes fly?
I think your friend might not have been right to get mad at you, but you were pretty off about QP.
I suspect that if anyone in the Fediverse can do a laser diffraction experiment at home it would be you.
