SECOND LAW

The Second Law is even more important than water for the creation of life. The Second Law, in its simplest form, can be stated, “Matter and energy tend to spread.” What is so meaningful about that simple sentence. After all, it is not surprising that cream spreads into coffee when stirred. We think of disorder as matter and energy that are well spread. We give this disorder the name “entropy.” The Second Law states that the entropy of matter and energy increases or, at minimum, does not decrease. An implication of this law is that all the matter and energy in the universe will eventually become a uniform heated soup. There will be no structure to the universe. Physicists usually say, The Universe will die in a random heat bath.”

BIG IDEAS IN SCIENCE, ART, AND SOCIETY

Hello fellow space-time travelers. My name is Roger Jones. I am coming to you from steamy downtown Pensacola, Florida. It is 7:30 in the morning in late June, so you can see the morning sun streaming through the east-facing windows behind me. This is the first post on this channel, TheX-Press channel, so I thought…

Water and Magic

Full fathom five thy father lies.

Of his bones are coral made.

Those are pearls that were his eyes.

Nothing of him that doth fade,

But doth suffer a sea-change

Into something rich and strange.

Sea-nymphs hourly ring his knell

Tempest, Act 1, Scene 2

Thought Experiments

A thought, or gedanken, experiment is the creation of a simplified, often fanciful, world for the purpose of understanding the implications of a theory. One of the first was Plato’s allegory of the cave, in which Plato postulates that people are only able to sense a part of the universe about them. The allegory explores what that means and implies. The real value of thought experiments is to generate hypotheses that can be tested in the real world.
