The best technologies are *physics hacks*.
Refrigeration works by compressing air to temporarily make it hot and reverse a temperature gradient. Airplanes trick the air below a wing into pushing the wing up by shaping airflow to reduce the pressure on top.
So much of what we call "tech" these days is just "follow a list of instructions, millions of times per second". I'm not impressed, Silicon Valley. ;)
What are some of your all's favorite physics-hack techs?
A nice little Mastodon instance. Mild trolling encouraged (keep it local), but not required. Malicious behaviour is not tolerated. Follow Wheaton's law and you'll be fine.
