Hope Springs Eternal


One of the characteristics that set humans apart from most other creatures is our ability to see into the future; to travel ahead in time. It’s what helps us plan. We can for instance, make a decision to go grocery shopping even though we just eaten a big meal; we know we’ll be hungry later, and we’re out of eggs, so we shop.

The Theory of Relativity


The Relativity Theory was first identified by Ernst Heinrich Weber (June 24, 1795 – January 26, 1878) a German physician who is considered to be one of the founders of experimental psychology. His work measured our ability to perceive differences in weight (that is lifted or held) and found that your ability to perceive change is relative to what you start with.
