I have two questions: - If pulse waves 'aren't propelled by the explosion', what propels them?

- Why would seeing a pulse wave in nitrocellulose prove that it's an explosive (as you claim), if you're defining pulse waves as any sonic wave?

I'm having a hard time understanding your position, or your reasoning for why nitrocellulose isn't an explosive. I also still haven't been able to find any resources that corroborate what you're saying.

I can't quickly find any resources that distinguishes between a 'shock wave' and a 'pulse wave' in the context of explosions. Do you have some resources?

If you're defining pulse wave as a sub-sonic pressure wave, deflagarations can definitely produce those, even with relatively poor fuels (e.g. wood dust). Why do you expect nitrocellulose couldn't? Not enough gas volume?

https://en.wikipedia.org/wiki/Explosion

>An explosion is a rapid expansion in volume associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel through shock waves. Subsonic explosions are created by low explosives through a slower combustion process known as deflagration.

Doesn't have to be supersonic to be an explosion. This is a disagreement about definitions, not about the properties of nitrocellulose.

There's little evidence that raw milk has higher "nutritional quality". Taste you can make an argument for, and raw milk is definitely required for yogurt & cheese if you don't want to introduce your own cultures.

I'd also note that "pasteurization" can mean different things in different countries. In Europe it's usually more extreme than in the U.S., as the milk is heated ~60 °C higher for a shorter period.

But you do realize that the environmental cost of animal farming is guaranteed to be >10x the cost of plant farming, correct? Each step up the food chain wastes roughly 90% of the energy, meaning that you need to grow more than 10 kcal of plants to raise 1 kcal of animal. So feeding animals is 10x as expensive as growing plants, in addition to the costs incurred by actually raising the livestock.

This isn't really the best measure though, because it only counts # of paths at the minimum depth level.

edit: although I found some deep searches with very few links: https://www.sixdegreesofwikipedia.com/?source=Frank%E2%80%93...
