Ask HN: Why is nearing completion so demotivating?

When your project is finished, the dream is dead and the reality is born. The death of a dream is like the death of a friend. It’s probably been with you for a long time — longer even than the length of the project. A dream is the manifestation of what’s possible. When it is over, the possible diminishes very quickly and you are left with what actually is. Will people respond well to your project — in the dream stage it is possible; everything is possible. In the reality stage, it will only be what it is.

So while it’s common to think of a release as a birth of something new, realise that you also have a significant loss. You will mourn that loss. Give yourself some emotional space to deal with the mourning.

Reality 4.2

Posted on by

One’s own pain cannot be fake, because by definition, one’s own pain is personal.

Pain itself is a feeling, not a description of one’s external reality, although the source can be.

Ultimate Freedom, 2

Posted on by

Imagination is not an empirical or superadded power of consciousness, it is the whole of consciousness as it realizes its freedom.

— Jean-Paul Sartre

.

Your mental world/software world lies your ultimate freedom.

It is where anything not forbidden can happen.

It is where anything logically consistent can happen.

Lee’s event realism ~ past realism

should be transcended by now-realism, in which the past is part of the present.

事件實在論，更正

Posted on by

Event Realism | 事件實在論 6.1

.

exist = can be found

無後果，就不再存在。

— Me@2013.09.25

.

If the consequences of an event cannot be found anymore, that event no longer exists.

— Me@2019.09.05

.

The surprising implications of the original delayed-choice experiment led Wheeler to the conclusion that “no phenomenon is a phenomenon until it is an observed phenomenon”, which is a very radical position. Wheeler famously said that the “past has no existence except as recorded in the present“, and that the Universe does not “exist, out there independent of all acts of observation”.

「事件」並不完全「實在」。

實在 ~ 堅實地存在

仍然有後果的事件，才為之「仍然存在」。

永久地有後果的事件，才為之「實在」。

Reality 4

Posted on by

“Real” has meanings other more than “lasting“.

For example, “pain is real” means “pain is objective“, instead of “pain is lasting“. 

real

~ objective

lasting

~ independent of time (to a certain extent)

real

~ independent of most of the things

~ constant with respect to most of the things

Consciousness 4

Event Realism 3.2 | 事件實在論 3.2 | Cumulative concept of time, 17.2

being conscious

~ having one’s own past information

~ having memory

~ having self-interaction

~ entanglement between past states and the present state

~ some of the past states keep existing through memories and records

~ past-self-and-present-self entanglement

Truth and Reality

Posted on by

真確與真實

“Real” is for objects (zeroth-order statements):

it is a real X

= it is an X

e.g.

it is not a real car

= it looks like a car, but it is not a car

“True” is for statements (first-order statements).

“Y” is true

= Y

“Y” is false

= Not Y

e.g.

“Snow is white” is true

= Snow is white

“Snow is white” is false

= Snow is not white

The relation between “Real” and “True” is:

“it looks like an X and it is X” is true

= X is real

Explanation:

“it looks like an X and it is X” is true

= it looks like an X and it is X

= X is real

memory ~ information of the past

Part of the past still exists, in the sense that some states and events of the past are entangled with those of the present.

Virtual particle

Posted on by

The Matrix, 4

However, the longer a virtual particle exists, the more closely it adheres to the mass-shell relation. A “virtual” particle that exists for an arbitrarily long time is simply an ordinary particle.

However, all particles have a finite lifetime, as they are created and eventually destroyed by some processes. As such, there is no absolute distinction between “real” and “virtual” particles. In practice, the lifetime of “ordinary” particles is far longer than the lifetime of the virtual particles that contribute to processes in particle physics, and as such the distinction is useful to make.

— Wikipedia on Virtual particle

The difference between the real world and a virtual world is that reality lasts longer.

Pains

Posted on by

Pains occupy a distinct and vital place in the philosophy of mind for several reasons. One is that pains seem to collapse the appearance/reality distinction. If an object appears to you to be red it might not be so in reality, but if you seem to yourself to be in pain you must be so: there can be no case here of seeming at all. At the same time, one cannot feel another person’s pain, but only infer it from their behavior and their reports of it.

Imaginary mass

Posted on by

Complex mass and decay rate

The mass of an unstable particle is formally a complex number, with the real part being its mass in the usual sense, and the imaginary part being its decay rate in natural units.

When the imaginary part is large compared to the real part, the particle is usually thought of as a resonance more than a particle.

For a particle of mass , the particle can travel for time 1/M, but decays after time of order of . If > M then the particle usually decays before it completes its travel.

Gamification

Posted on by

The Problem with Gamification is that it tries to solve a problem that doesn’t exist. We already have a universal points system, across all aspects of life, that represents status and is redeemable for real world prizes. It’s called “money.”
