North Korea Arms Reduction

US expert proposes arm reductions approach over denuclearization of N. Korea

Best idea so far. China will not push North Korea to denuclearize, so sanctions have failed. North Korea will not accept rewards to denuclearize as several agreements the past have been nullified.

Only option left is to limit the number of nuclear weapons and prevent proliferation, or keep sanctioning and try to isolate North Korea but it will have Russia, China, Iran and other allies.

Free Energy Principle And Cognition

According to Wikipedia -

The free energy principle is a theory in cognitive science that attempts to explain how living and non-living systems remain in non-equilibrium steady-states by restricting themselves to a limited number of states. It establishes that systems minimise a free energy function of their internal states (not to be confused with thermodynamic free energy), which entail beliefs about hidden states in their environment. The implicit minimisation of free energy is formally related to variational Bayesian methods and was originally introduced by Karl Friston as an explanation for embodied perception in neuroscience,[1] where it is also known as active inference.

The notion that self-organising biological systems – like a cell or brain – can be understood as minimising variational free energy is based upon Helmholtz’s work on unconscious inference[8] and subsequent treatments in psychology[9] and machine learning.

Free energy principle is also used in psychology and artificial intelligence.

Using the free energy principle, researches were able to grow neurons and enable them to play Pong.

Medicine Sometimes Cheaper Without Insurance In US?

Frustrated pharmacists are opting out of the insurance system, saving some customers hundreds of dollars a month

Propecia, treatment for hair loss, costs $124 a month in the US and around $40 a month in Korea. I used to buy Propecia until a few years ago when I found out that the generic version, Finasteride, costs about $15 a month.

Wormholes Or Another Dimension?

Black Holes May Hide a Mind-Bending Secret About Our Universe

The New York Times article is about black holes, wormholes, and quantum entanglement.

Keep imagining that wormholes and quantum entanglement are evidence of a non-local dimension. Why?




Korean Media Compliments Moon Administration Policies?

This has not ever happened before. The mostly conservative media has always criticized and incited anger against the Moon administration. Why become objective all of a sudden? Sort of scary.

If President Yoon, the ruling conservative party, and most of the Korean media criticize and slander the previous Moon Jae-in administration in concert, then Korean media would likely lose credibility and seem to be under Yoon's control. 

In an unusual move, Korean media has complimented the Moon administration efforts to reel in real estate loans the past few years due a booming real estate market caused by low interest rates. Recent drops in real estate prices have caused concern about foreclosures. Luckily, the criteria for real estate loans were set high enough that the drop in real estate prices will not result in foreclosures.

There was another report that stated that Yoon's policy on North Korea is the same as Moon's since they both promise economic aid in return for nuclear disarmament. Normally, the media states that Moon's administration is giving money to North Korea while South Koreans go lacking, is pro-North Korea, ignoring North Korea's human rights violations, and the like. Never a good word or comparison.

A lot of Koreans like and respect former President Moon, all the criticism is probably reflected in Yoon's low approval ratings in spite of the president's office constant daily public relations efforts.

OPEC Antidote?

Why haven't all the oil buyers and non-OPEC oil producers formed a cartel or group to counter OPEC?

At least the oil buying nations. Start stockpiling secretly, wait till OPEC is financially stressed due to ambitious projects and then negotiate reasonable prices?

Oil prices shouldn't be a big matter in a couple of decades. OPEC countries know that.

Cognitively dissonant people seem to almost always accuse others or opponents of crimes and unethical actions that they have been doing. 

Putin accusing Ukraine of terrorism. Kind of rich.

President Yoon accusing others of corruption and dishonesty.

Trump accusing the FBI of crimes and dishonesty.

Korean conservative party accusing others of dividing the nation, inciting anger and violence, and corruption.

Why? That is their world. That is all they see. That is the way of their world.



Remote Working Trend?

Most major American corporations employ remote workers. Why? They are contracted workers with little benefits and paid less than in-office employees. So, the trend should become even more pervasive.
