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…

The US has leapfrogged Singapore and Hong Kong to top IMD’s latest World Competitiveness Rankings. The top five most competitive economies in the world remain the same since 2016, but their order has changed. With the US at the top, Hong Kong has dropped one spot to second and Singapore remains third. Germany has fallen two spots to 15th and the UK has slipped one position to 20th.

Suites are the crown jewel of the hotel experience: generally, they’re more spacious, more meticulously appointed, and well-suited to house larger groups looking to share a space. 

There’s only one problem: they’re typically a lot more expensive than standard ho...

Second Day of Bullish Defense

The market had initially reacted to Trump's decision to cancel his North Korean summit before coming to its senses and finishing where it left off yesterday.

For the Russell 2000 it was a bullish doji to follow the 'hammer'; those brave enough to buy the morning dip will be feeling confident as technicals remain bullish.

How the US Government Could Effectively Use Crypto

The US government could start, or officially endorse an existing crytpo coin. What they would do is build a fee into the software protocol that went to a single address that they control. This is effectively a tax. The fee could be a transaction fee, a percentage of the next block award, or a combination of both. How this works is every single transaction that occurs everywhere wihtin the system, the fee scalped goes directly to this single address that is owned by the IRS, in this case, the "New-IRS." Forget postcards. We're down to a single dude in one office chair in front of one computer. Imagine that being the IRS, because that's where this is going. The consequences of this mechanism are dramatic. First off the IRS is now one guy. Granted, this guy controls the private key for the most valuable thing in the world. This key would be the single most important key right up there with the nuclear launch code, but the system would most definitely still work. More strikingly, the US...

In 2013, Kyoto University’s Shinya Yamanaka was awarded one of the first Breakthrough Prizes in Life Sciences for his discovery of “induced” stem cells that enabled researchers to convert adult cells back into stem cells.

The Breakthrough Prize is not to be sneezed at. Founded in 2013, the prize “honours transformative advances toward understanding living systems and extending human life.” It’s also the most financially attractive aw...

Buffett At His Best

By csinvesting. Originally published at ValueWalk.

Bear with me as I share a bit of my history that helped me create SkyVu and the Battle Bears games. The University of Nebraska gave me my first job after college. I mostly pushed TV carts around, edited videos for professors or the occasional speaker event. One day, Warren Buffet came to campus to speak to the College of Business. I didn’t think much of this speech at the time but I saved it for some reason. 15 years later, as a founder of my own company, I watch and listen to this particular speech every year to remind myself of the fundamentals and values Mr. Buffett looks for. He’s addressing business students at his alma mater, so I think his style here is a bit more ‘close to home’ than in his other speeches. Hopefully many of you find great value in this video like I have. Sorry for the VHS...

The Stock Bull Market Stops Here!

 

The Stock Bull Market Stops Here!

The definition of a bull market or bull trends widely vary. One of the more common criteria for bull markets is determined by the asset being above or below its 200 day moving average.

In my humble opinion, each index above remains in a bull trend, as triple support (200-day moving averages, 2-year rising support lines, and February lows) are still in play ...

The tricks propagandists use to beat science

Via Jean-Luc

How propagandist beat science – they did it for the tobacco industry and now it's in favor of the energy companies:

The tricks propagandists use to beat science

The original tobacco strategy involved several lines of attack. One of these was to fund research that supported the industry and then publish only the results that fit the required narrative. “For instance, in 1954 the TIRC distributed a pamphlet entitled ‘A Scientific Perspective on the Cigarette Controversy’ to nearly 200,000 doctors, journalists, and policy-makers, in which they emphasized favorable research and questioned results supporting the contrary view,” say Weatherall and co, who call this approach biased production.

A second approach promoted independent research that happened to support ...
