How can we see an atom
WebIt sounds weird, but you’re mostly empty space, so do your office, car, friends, all this universe. The size of an atom is governed by the average of its electron positions, the distance between the nucleus and electrons. The kernel is 100,000 times smaller than its atom. If the core is the size of a peanut, the atom would be a football ... WebThis week Reactions takes a close up look at the science of how we can see an atom.

Obviously, we cannot see atoms with our naked eyes. We cannot see atoms even with a very powerful microscope. To see something, we need light, an electromagnetic wave. This electromagnetic wave hits the surface of an object and gets reflected back from it into our ...
WebEngineering Computer Science Define an atom to represent an empty tree and use a term with a function symbol to represent a non-empty binary tree. Write prolog code so we can check whether a binary tree is symmetric. Other than append, length, member, \+, any predicate you need must be defined by yourself. You cannot use predicates read, write.
