Talking ‘baby talk’ to a baby where adults change the pitch in their voice is necessary for a healthy growing brain. Studies have found that babies not subjected to this grow up with cognitive problems later in life.

Since 1982 artists have been using fractals to make more realization landscapes. In the movie Star Trek II: The Wrath of Khan fractals were used for the first time in movie graphics to show the effects of the Genesis Device.

The most famous equation in physics is probably E = m times c squared.That is true for a stationary objects. The full equation is really E squared = (p times (c squared) squared) times (m times c squared) squared) where p is momentum. When an object isn’t moving then momentum is zero and you get the abbreviated and more famous equation.

The mass of every person can be calculated by adding up the mass of all the protons and neutrons from each atom in us. HOWEVER…protons and neutrons are made up of quarks and when you add up the mass of the quarks they are only about 2% the mass of an atom. Quarks move at incredible speeds inside a very small area in a proton and neutron so they store a great deal of potential energy and because of the equivalence of energy and mass that is where the extra mass is located.

Readers of this blog may recall that I have blogged on the fact that you cannot go faster than the speed of light because mass increases as you approach the speed of light. WRONG! It is actually inertia that increases. Inertia and mass are basically the same thing at low speeds and physics professors use ‘relativistic mass’ to help teach students about the concepts of going fast. Advanced physics students have to be untaught this concept.

Einstein predicted that clocks run at different rates in different gravitational fields. This has been proven to be true. We now have clocks so precise that we can see two clocks run at different speeds when one is positioned just one foot higher than the other one.
