my science discovery: atoms

An atom is the basic unit of a chemical element.atoms make up everything in the universe. Also atoms are made up of protons, electrons and neutrons.Protons carry a positive charge, electrons carry a neutral charge and finally neutrons carry a positive charge. Some atoms have different amounts of protons, electrons and neutrons.For example a carbon atom has exactly six of each. Some atoms dont have protons, electrons and neutrons, the hydrogen atom is one of them. It only has one electron and one proton.

my science discovery: computers

A computer is a general purpose device that can be programmed to carry out a set of logical operations automatically. Also since a sequence of operations can be readily changed, the computer can solve more than one kind of problem. Konrad Zuse was the first to make a freely programmable computer.
