# The 4 bugs of quantum mechanics popular, 1.4

A misnomer collection:

2.2.1.

Wave function is not a wave. It is not a physical wave.

2.2.2.

Uncertainty principle is not about uncertainty. It is not directly related to uncertainty.

Uncertainty principle is not a principle. It is not even a physical law. Instead, it is a statistical relation. It is an inequality about the standard deviations of two conjugate variables.

2.2.3.

Superposition state is not a superposition. It is not a physical superposition. It is not a superposition of physical waves.

Superposition state is not a state. Instead, it is a property of a physical system. It is a statistical property of a variable of an experimental setup.

2.2.4.

Quantum mechanics is not quantum. It is not just about quantum (particle of energy).

Quantum mechanics is not mechanics. It is not just about mechanics. It is not just physical laws. Instead, it is a set of meta-laws, laws that physical laws themselves need to follow. It is an operating system on which physical laws can run.

# The 4 bugs of quantum mechanics popular, 1.3

The common quantum mechanics “paradoxes” are induced by 4 main misunderstandings.

1.  `A wave function is of a particle.` Wrong.

2.1  `A system's wave function exists in physical spacetime.` Wrong.

physical definition

~ define the microscopic events in terms of observable physical phenomena such as the change of readings of the measuring device

~ `define` unobservable events in terms of observable events

— Me@2022-01-31 08:33:01 AM

superposition

~ lack of the existence of measuring device to provide the `physical definitions` for the (difference between) microscopic events

— Me@2022-02-12 10:22:09 AM

a physical variable X is in a superposition state

~ X has no `physical definition`

~ in the experiment-setup design, no measurement device is allowed to exist to provide a definition of different possible values of X

— Me@2022-02-18 02:04:45 PM

2.2   `A superposition state is a physical superposition of a physical state.` Wrong.

“Quantum state” is a misnomer. It is not a (physical) state. It is a (mathematical) property. It is a system property (of a physical variable) of an experimental-setup design.

“State” and “property” have identical meanings except that:

`State is physical. It exists in physical time. In other words, a system's state changes with time.`

``` ```

`Property is mathematical. It is timeless. In other words, a system's property does not change. (If you insist on changing a system's property, that system will become, actually, another system.)`

For example, “having two wheels” is a bicycle’s property; but the speed is a state, not a property of that bicycle.

superposition state

~ physically-undefined property

.

In the phrase “superposition state”, the word “superposition” is also a misnomer.

A superposition state is not of physical waves, nor of physical states. Instead, it is a superposition of physical meanings of some variables in a physical system.

a physical variable X is in a superposition state

~ X is a physically-undefined property (of the physical system)

# Sharp, 2

The beauty of doing nothing is that you can do it perfectly. Only when you do something is it almost impossible to do it without mistakes.

Therefore people who are contributing nothing to society, except their constant criticisms, can feel both intellectually and morally superior.

「反白論」的意思是，現時的地球人間，極多的情況下，名義與實情都是相反的。

As a rule of thumb, the more qualifiers there are before the name of a country, the more corrupt the rulers. A country called The Socialist People’s Democratic Republic of X is probably the last place in the world you’d want to live.

# The best software

My point today is that, if we wish to count lines of code, we should not regard them as “lines produced” but as “lines spent”: the current conventional wisdom is so foolish as to book that count on the wrong side of the ledger. — E. W. Dijkstra

# 反白論起點 2.2

「無事發生」，就即是「無災無難」。「無災無難」，近乎是一個奇蹟。所以，單單是「無事發生」本身，就要領袖，以至是全體的大部分人民，十分刻意、十分艱苦的經營。

# 反白論起點 2.1

Chapter 17 (第十七章)

Great rulers are hardly known by their subjects,
Then come those the people draw near and praise,
Then those the people hold in fear,
Then those the people revile.
When one lacks trust, one finds no trust.

Reluctantly, without boasting;
Perform actions, accomplish deeds;
The people will say it happened naturally.

# The paradox of happiness solved

It is often said that we fail to attain pleasures if we deliberately seek them. This has been described variously, by many:

Viktor Frankl in Man’s Search for Meaning:

Happiness cannot be pursued; it must ensue, and it only does so as the unintended side effect of one’s personal dedication to a cause greater than oneself …

— Wikipedia on Paradox of hedonism

If you do good work, you will feel happy.

However, if you do good work only because of the desire of getting happiness, you will not get it.

[selfless]

happiness ~ progress ~ self transcendence

do good work ~ keep going to the next levels

[selfish]

seeking happiness directly ~ focus on oneself ~ trapped at the same level

no progress ~ unhappiness

I like your Christ. I do not like your Christians. Your Christians are so unlike your Christ. The materialism of affluent Christian countries appears to contradict the claims of Jesus Christ that says it’s not possible to worship both Mammon and God at the same time.
