This is a big deal in the kitchen, workshop, and household cleaning. Just starting this article.
Most everyday liquids are either water-based or oil-based. More generally things are either hydrophilic (water loving) or oleophilic (oil loving).
Continue reading Oil and Water Don’t Mix1) Everything is chemistry. Well, not literally everything, but all the things we interact with daily like food, shampoo, clothes, furniture, building materials and such. And the fields of nutrition, medicine, industrial processes, biology, geology, environmental science, planetary science and a lot of astronomy.
Continue reading Chemistry is AmazingWith two interacting bodies, interacting via the r-squared forces of gravity or electricity, and obeying classical mechanics, the equation of motion can be written down in closed form.
With three interacting bodies, the equation of motion can’t be written down in closed form.
So the three-body problem can’t be solved exactly (and this is just for classical mechanics and r-squared forces). Algebraic approximations or numerical simulations can do a good job, but they’re not exact.
So what’s it mean?
