General Lee

General Robert E. Lee married Mary Custis, grand step-daughter of George Washington.  Thru this marriage he acquired slaves.  He freed them by 1862, following the instructions of his father-in-law’s will. Lee did not find slavery completely without justification.  [it was] “a greater evil to the white man than to the black race. . . blacks […]

Stuff of Reality

What something is, is different from what something is not.   It is fundamental logical truth that when something is something, it can not also, then, be what it is not. What physicists seem to have found, however, is that the very basic stuff of reality. . . is both what it is and what it is […]

Tyrant Lizard King

600 million years ago, in the Burgess Shale fossils of Canada, one can see dramatic changes happening in evolution.  Life is exploding in form and diversity.  Nature is experimenting wildly, with body shapes, body parts, eyes, and heads, fossils that look like Pixar animation.  We aren’t sure why, but at that time, animals started eating other animals […]

Science Priest

Isaac Newton got the concepts right, perhaps better than anyone else in history.    Mass is quantity of matter.  Momentum is quantity of motion. Force is change in motion. Change of motion is acceleration.  Mass is resistance to force.  Force equals mass times acceleration. F=ma This equation “is the basis of our mechanical, civil, hydraulic, acoustic, […]

Alien

A fish won’t stare at you, but an octopus will.  They watch you, with their human-like camera eyes, as much as you watch them. They are the smartest animal that has stayed in the sea, the only invertebrate – animals with no backbone – with a large brain.   Though as primitive as shell fish, […]

Math and Truth

“How is it possible that mathematics, a product of human thought that is independent of experience, fits so excellently the objects of physical reality?”  Albert Einstein. In 1939, at Cambridge University, Ludwig Wittgenstein was lecturing on the Philosophy of Mathematics.  By this time, with messianic certainty, he was adamant that mathematics was just a lot […]

Time and NOW

“What then is time?  If no one asks me, I know what it is.  If I wish to explain it to him who asks, I do not know.”  St. Augustine of Hippo. Everywhere in archeology, in the pyramids of Giza, the stones of  Stonehenge, the observatory of Chichen Itza, or the temples of Angkor Was, […]

Laureate

There is singing, and then there is singing. Bob Dylan does singing.  Listen to  ‘House of the rising Sun’, on his very first album. Malcolm Gladwell speaks of innovators, people who are always different.  They wear odd clothes, and in ways that others don’t and wouldn’t.  They start fads, but they don’t follow them.  They […]
