Marking the transition from observational to computational astronomy! A big advance...

Think of it this way. Almost as soon as Newton figured out how the planets should move in orbit, others realized they could use the "wiggles" (small errors observed) in the orbit to calculate the location, size, mass, etc. of another unknown planet whose gravity caused the wiggles.

And there it was, right where the theorists said it should be! A stunning accomplishment!

Chapter 15

The main point here is Darwin's (and Wallace's) recognition that species change to meet changing circumstances, no argument there.

But if you listen closely, you will hear faint echoes of a fascinating conflict that once raged between the "Ancient Catastrophe" theory of Earth's formation and the ultimately simpler "Uniformitarian" concept.

Makes one feel like sharpening Occam's Razor... :lol:

Okay, thank you. I'll probably get my wrist slapped for "bad form," but I did mark it PL OK myself. :roll:

Cheers,

Chapter 17
https://librivox.org/uploads/craigdav1/introhistoryofscience_17_libby_128kb.mp3 (22:54)

I can't let this one pass...

It's quite true that the great scientist Langley almost succeeded in demonstrating a man-carrying, heavier-than-air flying machine in October 1903. He must have had an especially patient engineer, who survived two duckings into the frigid Potomac River. :lol:

The honor of being first is generally accorded to the Wright brothers (December 17, 1903). Said to be "mere bicycle mechanics," Wilbur especially was a competent scientist and engineer who made many wind-tunnel studies of aerofoils in developing the first successful Wright machine.

Odd that Bleriot, the French aviator/scientist gets a mention, probably because he adopted Langley's approach. But the chapter completely omits mention of the brilliant Brazilian inventor Alberto Santos-Dumont who scooped them all on October 23, 1906. Of his many successful flying machines, the "Demoiselle," which prefigured the modern ultralight aircraft, is my personal favorite. See "Wings of Madness" by Paul Hoffman.

Oh, well. We Americans have never been bashful about claiming to be "first." :roll:
