Agriculture and the Environment
Mar. 19th, 2019 02:01 pmOne problem with conventional farming is that it uses so many harmful pesticides. This is unhealthy for the environment, and unhealthy for humans as well.
Organic crops reduce this issue, but tend to introduce a different issue. Because it seems these crops generally require considerably more land and water to produce the same amount of product.
It's the same issue for animals that aren't given antibiotics (giving animals antibiotics is one vector for introducing extremely terrible antibiotic-resistant bacteria into the world) and grass fed livestock etc. These again produce lower yields per acre and unit of time.
I don't think this issue has any easy answers, but I think it's something that needs to be thought about if we want our food supply to truly be more environmentally friendly. I also think that people often don't think about their crops and livestock as being the invasive plants and animals that they often are.

The Quantum
Mar. 19th, 2019 10:14 pmIt annoys me when people use bad quantum physics analogies. Quantum physics is rather unintuitive to the human mind, but it's not some kind of magic physics that can be used to explain anything even vaguely mysterious. It does have very well-defined rules.
Also, quantum physics is broken, and we know it's broken, because it doesn't properly explain the things explained by relativistic physics! And of course relativity doesn't explain the things explained by quantum physics. That's how physicists know they haven't discovered everything there is to know about the universe. Well, that and the fact that the universe appears to be expanding ridiculously fast (and is in fact speeding up) in violation of everything we would expect given our current understanding.
Anyway. Quantum physics is cool, but it isn't magic.
