Thinking Like a Greek

We live in an age of specialization and compartmentalization. Science, religion, mathematics, politics, philosophy, and literature are separate fields of study. Each of these has dozens of sub-categories with their own terminologies and modes of thinking.

However, the ancient Greeks

didn't make a distinction between philosophy and science, nor did they recognize the range of disciplines such as physics, chemistry, mathematics, astronomy, etc. that we do today. There simply wasn't the depth of knowledge and range of information that later made separate disciplines practical. In the Greek era, one individual could be an expert in several fields.

The splintering of knowledge makes it difficult to recognize patterns that may cross knowledge silos. More importantly, some believe that there is a deeper underlying reality to the universe that is understood only piecemeal by experts in their respective specialties. No human being has yet fully grasped, much less been able to explain to his fellow creatures, such a reality.

In a book to be released this Tuesday, Professor of theoretical physics Heinrich Päs ponders the "One."

his book proposes, rather than a definitive answer, an exploration of both the mind-bending conclusions of modern physics and the long history of the beguiling notion of a unifying, universal fabric. His book proves a heady mix of history, philosophy and cutting-edge theory that is fascinating, provocative and at times infuriating.

I'm a sucker for these books that explain the nature of the universe, where it came from and where it's going. If the writer presumes to discuss the nature of man, then I must resist the temptation to tell him to stay in his lane, which in this case is theoretical physics. He's thinking like an ancient Greek.

You Can See It if You Look for It

Today's reading:

This is what the Lord God showed me: the Lord was standing beside a wall built with a plumb line, with a plumb line in his hand. And the Lord said to me, "Amos, what do you see?" And I said, "A plumb line." Then the Lord said,

"See, I am setting a plumb line in the midst of my people Israel; I will never again pass them by; the high places of Isaac shall be made desolate, and the sanctuaries of Israel shall be laid waste,and I will rise against the house of Jeroboam with the sword."----Amos 7:7-9

I didn't know much, nor cared, about construction through the first 30 years of my bookish life but over time grew to appreciate the skill of those in the trade. Even more astonishing were the feats of the engineers who built the seven wonders of the ancient world without the benefit of modern technology.

One essential tool that dates back thousands of years was the plumb bob, the weight that established a vertical "plumb line." (Today we use spirit levels which reveal the vertical and horizontal through air bubbles in liquid.)

The plumb line is an irresistible metaphor for the steadiness of God's word in a world of confusion. It's a metaphor that is not fully appreciated until one tries to build something without a tool that brings one back to the straight and vertical path.

Fun Fact: the original weights were made of lead (Latin: plumbum), hence the origin of plumb bob, plumb line, and lead's chemical symbol Pb.

Space archaeologist Alice Gorman says that gravity will be "the most precious commodity of the next space age." [bold added]

To maintain their bone density and muscle mass, crew members must exercise for over two hours each day. Without this discipline, the astronauts could end up with osteoporosis. Living in gravity so different from Earth’s has consequences, including vision impairment and diminished organ function...

Living in variable gravity environments makes gravity a commodity that it simply isn’t on Earth; it becomes foreground rather than background. Power may be determined by whomever controls access to specially designed, high-gravity environments where people can maintain their strength. Gravity may indeed be rationed, and depriving people of access could have serious health (and even legal) consequences.

Dr. Gorman quickly dispenses with the spinning-spaceship solution to artificial gravity:

The earliest space stations, such as the rotating wheel conceived by the Viennese engineer Hermann Noordung in 1929, were designed to produce “artificial” gravity by spinning, like the centrifuge astronauts train in.....In the 1960s, NASA considered spinning space stations, but decided that astronauts might not enjoy being spun like a sock in a washing machine. Having been in a gravity rotor in an amusement park, I can categorically say that I did not enjoy it.

I applaud Alice Gorman for thinking outside the capsule, but it seems that there are many features of earthly life--oxygen, natural food, copious running water, convenient sanitation, privacy, pets--that will be in short supply in space. I doubt gravity will be "the most precious", but then again she's the expert.
