“The human ear can detect only the sound which is produced through from 32,000 to 38,000 vibrations per second.
As the rate of vibrations per second increases above that which we call sound, they begin to manifest themselves in the form of heat. Heat begins with about 1,500,000 vibrations per second.
Still higher up the scale, vibrations begin to register in the form of light. 3,000,000 vibrations per second create violet light. Above this number vibration sheds ultra-violet rays (which are invisible to the naked eye) and other invisible radiations.” -Napoleon Hill
“In the world of physical matter, whether one is looking at the largest star that floats through the heavens or the smallest grain of sand to be found on earth, the object under observation is but an organized collection of molecules, atoms and electrons revolving around one another at inconceivable speed.
Every particle of physical matter is in a continuous state of highly agitated motion. Nothing is ever still, although nearly all physical matter may appear, to the physical eye, to be motionless. There is no ‘solid’ physical matter. The hardest piece of steel is but an organized mass of revolving molecules, atoms and electrons.” -Napoleon Hill
“The brain is remarkably adaptive. Like a muscle that gets stronger with use, the brain changes itself when you struggle to master a new challenge. In fact, there’s never a time in life when the brain is completely ‘fixed.’ Instead, all our lives, our neurons retain the potential to grow new connections with one another and to strengthen the ones we already have. What’s more, throughout adulthood, we maintain the ability to grow myelin, a sort of insulting sheath that protects neurons and speeds signals traveling between them.” -From, “Grit” By: Angela Duckworth
“Though the brain takes up only 2% of our body mass, it uses up 25% of our body’s energy.” -From, “You”
Theoretical Physicist, Sylvester James Gates Jr. Talks about his interest in physics and supersymmetry, and how to be a success. He seems like he could talk about science for days. It’s always inspirational to see someone love what they do.
