    I hate this phrase because it assumes that copyright infringement was at one point the same as stealing - it never was.

    Stealing is a crime, where you take with the intent to deprive. Copyright infringement is a civil offense where the original owner loses nothing.










  • Thank you for the correction on my terminology. Oil doesn’t dissolve in soap and soap doesn’t dissolve in water, emulsions are not solutions.

    However, I think the general point about oil attaching to the soap and the soap attaching to the water still stands. I would still say that “the soap attaches the oil to water” isn’t quite right. Per your statement, the soap attaches to both oil and water on opposite sides of the molecule, so the oil isn’t really attached to the water - at least not directly. That was the thing I was trying to articulate.

    But you also remind me of something a chemistry professor once told me: it’s not the soap that cleans, it’s not the heat that cleans, it’s the physical scrubbing action that cleans. Soap and heat make it much easier, but if you add soap and hot water to a burnt dish and leave it to soak, everything will stay exactly where it is (separated) until you add physical energy to move things.


  • Depends how much soap you use.

    The soap doesn’t work by attaching oil to water, the soap attaches to the water and then the soap is carried away by the water. Oil doesn’t dissolve in water, but oil dissolves in soap and soap dissolves in water. So long as you use enough of an excess of soap and mix it together enough, you’ll be fine.

    Definitely agree with rinsing the drain before, during, and after, though. Especially as most mammal oils become less viscous (slightly runny) at higher temperatures.





  • Could well be needed. It’s not fully understood, but human space travel - even to the surface of relatively nearby Mars - might not even be viable. Aside from the radiation issue after leaving the Earth’s magnetosphere, zero gravity changes the body. When astronauts land they’re carefully assisted to get out and placed onto soft bedding. From Chris Hadfield’s autobiography, merely standing up after coming home from a few weeks/couple months on the ISS was like standing on a bed of needles. It took about 2 weeks to be able to move around again, which makes me wonder how we’ll ever get people on the surface of Mars. The Moon is pretty easy in comparison, much lower gravity and not that far away.
