Dear Friends,
I apologize for my insistent and even obsessive since I became active at PDF in the last two. I have posted many things that are actually purely speculative, groundless, without a shred of evidence to support my beliefs or conclusions.
@Deino,
@gambit, @
pakistanipower, your criticisms are actually valid. I thought about what you have said. I can say without malice or anger that I accept what you said.
Do I (anyone) have evidence that J-20 can even break the sound barrier?
I don't.
Do I have evidence that J-20 can fly past Mach 2.0.
I don't.
Do I have evidence that J-20 can fly past Mach 2.0 and beyond.
I don't.
Do I have evidence that J-20 is flying with a version of WS-15?
I don't.
Do I have evidence that J-20 can do Supersonic Cruise?
I don't.
Do I have evidence that WS-15 is 150kN, 180kN, +200kN.
I don't.
Do I have evidence that WS-15, pasted all the tests, is operational, and in production? I don't.
Do I have even know what stage of development is WS-15 in?
I don't.
Do I know what empty weight of J-20?
I don't.
Do I know how much fuel does J-20 carries for demo or testing?
I don't.
Do I know the efficiency of WS-15 in terms of dry and wet thrust?
I don't.
Do I know what engine is J-20 using?
I don't.
In fact, my answers to all the above is as good as anyone's, and just as bad as anyone's.
I normally react with extreme anger when someone disagree with my beliefs or conclusion. And I am actually tired of it. That don't lead me anywhere. But I have been thinking about gratitude and appreciation about people around me. And how could I think differently that I would appreciate people more.
People disagree not because that I might be wrong. They disagreed because I don't have the evidence to support to my hunch/beliefs/opinion/conclusions.
And if I have it, show them. If I don't have it, learn more, dig in more. Don't blame it on another guys for don't belief in you.
I certainly do my own huge share of don't believe in other guys. I don't believe Gambit that F-35's problem could be fixed, for example.
In the beginning, I viewed Deino's disbelief or disagreement with anger, but come to think of it, there are huge amount of B.S, pure speculation, groundless beliefs in the world. His job is like an editor to keep them out of the Forum. People won't know or believe or change their minds, unless there is AMPLE, not just a little, evidence.
This is a good things. I do that too. In fact, plenty of it. That's why I have the reputation of being stubborn or obstinate or stiff necked. I don't change my mind, unless there is strong overwhelming evidence.
Why should I expect other behave not the way I do?
This is my mistake. I humbly accept your criticisms and will try not to be obsessive/compulsive.
Sincerely,
Asok.
