The Scientific Method
Created in 1795 by the French Academy of Science to unify existing systems.
Original meter was one ten-millionth of the distance from North Pole to Equator along Prime Meridian.
In the early1900’s this was changed to a certain number of wavelengths of light from Kr-86. (605.78 nm)The Metric System

3. The 2 types of energy are Kinetic (due to motion, K = ½ mv²), and Potential (due to position, U = mgh).
4. Forms of energy are mechanical, electricity, magnetism, light, heat, sound, chemical, and nuclear. All can be inter-converted.
5. Matter can be converted to energy, E = mc². (Games.)

In a Bronx, N.Y., high school where the dropout rate was 60 percent, a guidance counselor declined to give Stephon Alexander an application to an Ivy League university.
"You won't get in," Alexander recalls the counselor saying. But Alexander proved the counselor wrong.
After a BS at Haverford and a Ph.D. in Physics from Brown University, the counselor appears to have gotten it wrong. After his Ph.D., Alexander was at London's Imperial College.
Currently he is a member of the SLAC high energy physics group and Stanford's ITP (Institute for Theoretical Physics).
