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…

Canada's Green Shift Could Displace Three-Quarters Of Oil Workers

Courtesy of Charles Kennedy, OilPrice.com

Canada’s climate strategy to significantly cut emissions and become a net-zero emissions economy by 2050 will create a seismic shift in the large oil and gas sector, where up to three-quarters of the workers, or up to 450,000 people, are at risk of displacement, TD Bank said in a new report on Tuesday.

Canada aims to become a net-zero emissions economy within three decades, and to cut emissions by between 32 percent and 40 percent by 2030.

While those commitments could be critical to staving off the worst effects of gl...

Gold Gann Angle Update

The Biden Yellen team have made their play, and it is not US dollar friendly.

Janet Yellen speech named "International Priorities — Remarks to The Chicago Council on Global Affairs" (here) can be summed to (via Luke Gromen) :


The US is accelerating a move away from "subjugating the US middle and working class to support the USD", to "subjugating the USD to support the US middle and working classes".



Well the above is true, but as we all know large US deficits and the trend of the US dollar are joined at the hip, and that trend is down '...

Gold; Load Up The Truck Upon Hitting This Level

Courtesy of Chris Kimble

Gold has created lower highs since peaking last summer. Is Gold near a low? Where would a nice entry point come into play?

This chart looks at Gold ETF (GLD) on a weekly basis over the past few years. GLD hit the top of this rising channel at (1) last summer, as it was above moving averages and relative strength was hitting lofty levels.

The decline over the past 7-months has GLD creating a death cross. Warren Buffett sold his Gold holding before this death cross took place!

Where would one want to pick up some GLD at a nice risk/reward price point?

If GLD reaches rising channel support at (2), w...

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Courtesy of Technical Traders

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

Texas, Florida, Arizona, Georgia – The Branch COVIDIANS Are Still Burning Down the House

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
