Laplace’s Hammer: The End of Economics

Laplace’s Hammer: The End of Economics

Courtesy of Tim at The Psy-Fi Blog 

Clever Man, Stupid Idea

Simon-Pierre LaplaceSimon-Pierre Laplace was a Very Clever Man who did many Very Clever Things. Unfortunately, like many clever men, having got hold of a Brilliant Idea he was rather inclined to go off and use it on everything in sight, which led to a number of Very Odd Conclusions. In fact as far as science goes, he may well have been the original man with a hammer; taking aim at every problem as though it was a nail.

As is the way of these things economists got hold of Laplace’s ideas, converted them to their own and started developing delicate and intricate webs of theories and practices. Unfortunately, over the succeeding three hundred years they’ve failed to keep up with advances in physics and biology, rather leaving economists as the only believers in an approach that suggests we have no free will, a position from which they’re having to be dug out and defused, one unexploded theorist at a time.

Newton’s Error

When Isaac Newton published his theory of gravity he knew it contained a serious flaw; his equations didn’t exactly match what was observed. He reckoned, correctly, that the differences between his theory and the observations were down to the gravitational effect on the planets of other planets – so called perturbations, which he didn’t know how to mathematically model. He said:

“But to consider simultaneously all these causes of motion and to define these motions by exact laws admitting of easy calculation exceeds, if I am not mistaken, the force of any human mind.”

And, of course, he was mistaken. The force of Laplace’s mind successfully solved the problem. Having achieved this, though, Laplace went a stage further. Because he could exactly calculate the position of any planet he could compare this with the results of observations from astronomers. What he discovered changed human history.

Observer Bias

It turned out that observers made errors, but they made them in a particular way – their observations fell about the actual position of the planet in a very distinctive pattern. This pattern, of course, was the ultra-familiar Bell curve or normal distribution. Laplace realised that human error was statistically quantifiable and, therefore, could be effectively eliminated from the data. This…

It Is Seven Times More Difficult To Get A Flight Attendant Job At Delta Than Enter Harvard

Courtesy of ZeroHedge. View original post here.

One of our preferred "off beat" economic indicators is how many workers apply at any one given moment in time for jobs that are hardly considered career-track. An example of this is the number of applicants for minimum wage line cook jobs at McDonalds, or flight attendant positions at Delta Airlines; conveniently, this is a series which we have tracked on and off for the past 7 years.

Large Caps Accelerate Gains; Small Caps Breakout

Courtesy of Declan.

Friday belonged to Large Cap stocks as both S&P and Dow Industrials posted gains which looked better than the less than 1% they managed. Volume climbed to register accumulation. Technicals are healthy and the S&P posted a new 'buy' trigger relative to the Russell 2000 (Small Caps).  This may end up as a blow-off top but there is nothing in Friday's action to suggest such a top is in place.

An Evening in Wonderland

 

An Evening in Wonderland

You walk halfway across Rivington Street and in the middle of the block there’s an alley leading north, and then, inexplicably, it curves northwest. It’s remarkable in that on the Isle of Manhattan there aren’t any alleys. And this one is whimsical. Lights are strung overhead and artwork decorates the sides of the buildings as you make your way through. And then, at the end of Freemans Alley, you come to a tucked away restaurant in the back corner. It’s called Freemans (what else?).

Today, the “beautiful mechanism” of the body clock, and the group of cells in our brain where it all happens, have shot to prominence. The 2017 Nobel Prize in Physiology or Medicine has been awarded to Jeffrey C. Hall, Michael Rosbash and Michael W. Young for their work on describing the molecular cogs and wheels inside our biological clock.

Day of Last Dances

News today has been relentlessly terrible. A horrific mass murder happened last night in Las Vegas. (Our politician's abject failure to address gun control is beyond sickening.) And today, reports that Tom Petty died of a heart attack, followed by reports that Tom Petty is not dead, and now reports confirming that Tom Petty has passed away.
