(Phys.org)—Within the cell chemical messages are passed through a signaling cascade. This cascade can be a series of chemical reactions or molecular changes that spurn the next reaction in a kind of assembly line process. ...
In quantum mechanics particles can behave as waves and take many paths through an experiment. It requires only combinations of pairs of paths, rather than three or more, to determine the probability for a particle to arrive ...
