- The thing that leaps out at me from this list is that, over and over,
- Velikovsky says that such-and-such "should" be so, but he never actually
- goes in and shows, quantitatively, why this is so. For example, he says
- the atmosphere "should" separate (due to differing densities of gasses
- in the mix), but he doesn't go on to show how clean the separation
- "ought" to be. He says that planets "should" not have become spherical
- (presumably due to tidal effects, though this is not made explicit), but
- he never calculates how large this effect is. He says that the
- distribution of ice, snow, ocean currents, and the like "ought" to
- affect the earth's "equilibrium", but doesn't ever calculate how the
- mass of the atmosphere and water on the earth compares to the whole.
- The sun's rotation "should" have an effect, but he never calculates how
- large, nor does he account for the fact that the movement of features on
- the solar surface shows that the sun is fluid, and the rotation we
- observe may not reflect the motion of the whole sun. And so on and on.
-
- The point is, Velikovsky, and Ted much like him, sees things in little
- black and white pseudo-logical categories. They use fuzzy, qualitative
- reasoning in places where many conflicting quantatively graded effects
- are involved, and then by sheer assertion pick one of these effects and
- pronounce it dominant over all the others, without ever going to the
- trouble of calculating ANY of the effects involved.
-
- This, of course, is in addition of his blatant misunderstandings, eg
- about ozone, "perterbations due to reciprocal action" (perhaps planets
- are driven by pistons and cam shafts...), and so on.
-
- So, sadly, the fact that his apparent innumeracy leads him to understand
- physics poorly and incompletely (where he understands it at all) renders
- most of his pronouncements purest gibberish.
-
- This is also a halmark of Holden's analyses.
