"When somebody sounds like a total fucking crackpot, they almost always are."

Aristarchus of Samos sounded like a total fucking crackpot, and if you had called him out your prediction would have been right - for a couple millennia.

What if instead of taking your attitude, the Greeks had devoted their energy to developing better sensors to test Aristarchus's claims about the parallax motion of the stars? Instead of sitting around calling him a crackpot, we could have had an accepted heliocentric model of the solar system some 1800 years before Copernicus.

I just saw this article on today's front page:

The EM drive is controversial in that it appears to violate conventional physics and the law of conservation of momentum; the engine, invented by British scientist Roger Sawyer, converts electric power to thrust without the need for any propellant by bouncing microwaves within a closed container. So, with no expulsion of propellant, thereâ(TM)s nothing to balance the change in the spacecraftâ(TM)s momentum during acceleration.

No, science has never disproved the aether. It was ruled out for social reasons. When that social reality changes, science will probably bring it back. Yves Couder's experiments with silicon "walkers" bouncing on a liquid substrate, with which he can recreate Young's double-slit experiment on a macroscopic scale, would fit nicely with aether theory. But that fit is ignored by physics, because of the social ramifications of bringing back aether theory.

Even so.

$20 in 1913 was worth almost $500 today. But the nominal gdp per capita in 1913 was about $400, while in 2013 it was over $50000. So: $20 / $400 gdp per capita in 1913 = 0.05 or 5% of yearly income. $400 / $50000 = 0.008, or 0.8% of yearly income. Thus, purchasing power has increased since 1913. The equivalent of $20 today will buy you much more than you could get in 1913. That includes electronics that didn't exist in 1913: radios, wind-up LED lights, cell phones, etc.

Regarding your example of a good suit costing "in the thousands": 5% of $50000 is $2500. So your purchasing power has not decreased: you can spend the same percentage of yearly income on a suit, and get a very high quality one today, as you did in 1913. Also, there are so many electronic products that cost $infinity in 1913, such as computers, cellphones, TVs, and many other things we take for granted today.

The myth of inflation being such a destructive force is thus revealed to be hyperbole.

Purchasing power has advanced much faster than inflation. A common meme is "A suit cost $20 in 1913." But the GDP per capita in 1913 was much less. You can look it up (as I have) and you will find that as a percentage of GDP per capita, a suit today is something close to 5 times less than it was in 1913.

The money supply has increased significantly faster than inflation. The quantity theory of money is deeply flawed.

System restarting, wait...
