External vs Internal

I keep forgetting that external diagrams lose some info to elevate the level of abstraction. The lost info is partially (?) recovered by the introduction of the concepts of injective, surjective, bijective, etc.

If we considered economics to be a technology rather than science, we'd conclude that communism, socialism and libertarianism are wrong because no working system had been implemented using their designs. On the other hand, capitalism has multiple working implementations, ranging from the US to China to Sweden.

"Пикассо не изобрел ничего нового".

The statement is obviously untrue because he at least invented himself. The vast majority of people never manage to accomplish that. Can we show this formally?

TIL: China investing in Israel

Chinese money is increasingly flowing into Israeli hi-tech companies and is likely to overtake the US as the number one source of foreign investment for the Jewish state.

Phishing for Phools - making money on the Deplorables

Bloomberg Decrypted has a fascinating story about a guy who made millions of dollars by feeding conservatives garbage stories about Obama's concentration camps, etc. His business thrived until earlier this year Facebook decided to crack down on distribution of fake news.

Obama will soon take advantage of the law that Bush passed—but never used—under his administration. Bush passed a law that would allow the current President of the United States to declare martial law at their discretion under executive action—and we all know how much Obama loves to bypass congress. Once this is in place, the military will have the power to act as Obama’s henchmen, and throw any freedom loving patriots into these FEMA Camps.
