If positive charges and negative charges attract while negative charges repel each other, then why don’t the positive protons within an atom repel?
They do, it is just that the strong nuclear force, a force different from the electromagnetic force you are referencing, is much stronger and overwhelms the repulsion. It only acts when things are very close, as the internal distances of the nuclei of an atom, but it is incredibly strong. The electromagnetic force acts over … Read more
What factors determine the selection of methods of the separation of a mixture?
When approaching a separation problem, the first order of business is to identify what is different between the molecules (or ions) that you wish to separate. For example, if all of the molecules are hydrophobic but differ in the magnitude of their hydrophobicity, then a separation method based on hydrophobic interaction is a good choice. … Read more

How likely is it that the concept of the ‘Goldilocks Zone’ will yield a habitable planet with a breathable atmosphere?
Our Sun is a very ‘quiet’ star. For its size, it doesn’t produce a lot of damaging radiation. The amount of UV light it puts out is NOW countered by our atmosphere as Oxygen has produced Ozone which absorbs a lot of UVc. This Oxygen was initially produced by cyanobacteria in early development of the … Read more
Is quantum field theory derived from quantum mechanics or vice-versa?
Quantum Field Theory grew out of Quantum Mechanics, specifically, the need to make QM compliant with Special Relativity. In SR, space and time are on equal footing, and “mix together” when you switch reference frames. But, in vanilla QM, time is treated as a normal number (basically just a label), while the position in space … Read more
