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…

Has The Fed's Policy Decisions Propped Up Equities?

 

Has The Fed's Policy Decisions Propped Up Equities?

Courtesy of The Fat Pitch

Summary: The stock market rises on days when the FOMC releases its policy statement, probably as a result of some uncertainty being removed for market participants. This pattern has existed for more than 30 years. The Fed's ability to "jawbone" the market higher is no more exceptional now than it was during any prior bull market.

Sad Clown

A thought from Jean-Luc:

Every day that goes by brings more shady deals from Trump's past – now Cuba, more stuff about his foundation, his taxes! No wonder he doesn't want to release his taxes either – who the heck knows is buried in there.

In the meantime, Trump gets up at 5:00 AM to tweet about Alicia Machado! What a despicable coward little man-child!

Atrios sums up my feelings:

Sad Clown

I admit I find it hard to keep up the sense of humor about things these days. We laughed a lot during the Bush years, didn't we, my fellow pony aficionados. Trump should just make me laugh and laugh and laugh and laugh. But with Bush we could sorta pretend that people voted for him because they didn't quite see him for what he was. There's no doing that with Trump. Trump is Trump. He won't win, but a lot of...

LOTE: You Are Not Morally Obligated To Vote For The Lesser Of Two Evils

LOTE: You Are Not Morally Obligated To Vote For The Lesser Of Two Evils

“If Hitler were to invade Hell, I would at least make a favorable reference to the Devil in the House of Commons.” — Winston Churchill.

In Churchill’s estimation, Stalin was less evil than Hitler. Hence, the Allied Forces’ brief friendship with the Soviets: a marriage of convenience formed in Hell.

Every four years, Americans face the so-called lesser-of-two-evils (LOTE) dilemma: “Both major-party presidential candidates are lousy, but I’m duty-bound to vote. Free people get to co...

Epizyme - A Waiting Game

Reminder: Pharmboy is available to chat with Members, comments are found below each post.

Epizyme was founded in 2007, and trying to create drugs to treat patient's cancer by focusing on genetically-linked differences between normal and cancer cells. Cancer areas of focus include leukemia, Non-Hodgkin's lymphoma and breast cancer.  One of the Epizme cofounders, H. Robert Horvitz, won the Nobel Prize in Medicine in 2002 for "discoveries concerning genetic regulation of organ development and programmed cell death."

Before discussing the drug targets of Epizyme, understanding epigenetics is crucial to comprehend the company's goals.  

Genetic components are the DNA sequences that are 'inherited.'  Some of these genes are stronger than others in their expression (e.g., eye color).  Yet, some genes turn on or off due to external factors (environmental), and it is und...
