Totaly diffrent tech here. One uses a tube to enhance an electric charge the other uses a direct lazer to a glow paint to make an immage. Lazer would be more powerfull and can keep up with immage changes more than the typical crt projector. But the crt tube could hold an immage longer than the paint from the Lazer test. Some old black and white crt tubes still have the final immages burned in them from old arse shows they died on.

Ya, they are totally different of course. But that laser trick reminds me a lot of the phosphor coating on a CRT only in this case it's UV radiation in atmosphere instead of an electron beam in vacuum. Both are "painting" on a phosphor screen.

(please take no offense Kreearghm this is a general observation: ) Why is everyone so quick to tell grandma how to suck eggs these days? (and state the obvious) Or am I just getting that old that I see it now?

How about burn-in on the green or amber monochrome phosphor CRTs? Or better yet - an analog scope?

My supervising Prof is currently doing this to me too. Do I have a big "STUPID" stamp on my forehead or something?

Do I just skip too much detail and present concepts too complex for most people to comprehend without assistance? I think that is my problem. Aside from modesty of course. ;)

Actually, everyone does this to me, employers, family, friends,... everyone. Maybe there really is a big "STUPID" stamp on my forehead? I think I have to stop and take the time to explain everything out in detail to people, but I just do not have the time for that... tick, tock... gonna be dead soon.

This happens to me a lot too. From what I have figured out, it is caused merely by method of thought. The way that my brain links topics or organizes thoughts can be rather screwy compared to other people. I tend to make comparisons and observations that people either didn't think of or would make them look at me like I had three eyes.

I think Foas is on the right track there. I know I leave out a lot of information, at times, when I think it is well known. It would be like having a discussion on the History of Tachyon particals in the real world, and not having to mention George Sudarshans name.

Or a simpler example, Discussing a drowning death over memorial day weekend, and not commenting that water is wet.

But it is so much fun when they eventually have the "light go on behind their eyes" and realize that you are neither crazy nor stupid but saw as obvious something they missed entirely.   :angel:  At that point they have to think either "I've been so STUPID!" or that you are brilliant - rarely do people admit the stupid option ;) and your reputation for genius builds :) .

While an exaggeration I get your point. Reminds me of another thread here this morning... ;) I think you and FoaS have hit on the nut of it.

Problem is Nemesis, a reputation for genius sucks. Mostly because everyone expects what you say to be brilliant, and when it is, they just don't get 80% of it - but make one error and they get it for sure.

A philosophical question: Why does it seem so much easier/desirable to prove someone wrong than to prove someone right? Even our statistical jargon uses the counter intuitive term "null hypothesis" as the normal assumption in hypothesis testing. The whole logic structure of our minds seems built to prove things wrong, not right. it is incredible we get anything done.

People like to share knowledge, no question, there is reward in it, both for the ego and for altruistic reward. But too often it is confrontational, I catch myself doing it.

I guess Genesis asked the same question: "Why, why do we suffer each race to believe that no race has been grander?"

The problem is not only an individual one but a macrocultural one. I don't think I'll ever solve it, but a little more understanding helps.

Wait, let me listen to that again (for the four thousandth time...) I think they answer the question in the next line...:

"It seems because through time and space
Though names may change each face retains the mask it wore."

Hmm, not much of an answer, but I don't suppose I could do much better. Odd that I should listen to that song for 30 years and only notice that now.

Ah, I think what Pete is saying is that precisely because we are all really the same, that is itself the explanation. It makes sense in a tautological way.

Sometimes I feel like I'm still 10 years old. <shakes head>

That is easy - don't make mistakes they can understand.  ;)

Another thing is to make sure you point out potential failure modes.  Mostly they won't understand the whys of the failures but if they happen then you are still a genius.  ;)  It also helps when outside your field you point out your lack of knowledge and emphasize how you are guessing, guess right and its genius, guess wrong and it was just a guess and gets forgotten :) . 

I can give an example.  At my old job I was consulted (because of past insights) on a job that had nothing to do with me namely how to get a pump as close as possible under a blender without raising the blender any higher (it was too high already).  I took a look at the overall setup and said "cut a hole in the floor", unless there are conduits already in the floor in the way.  At first they had this "you're crazy look" followed by realizing that we were on the 2nd floor and their was over 20' of headroom above the ground to "squeeze" in the pump.  When they pointed out that they would need to move the blender ($$) to cut the hole I merely pointed out it would be easier to cut it in the ceiling, after a brief look up they understood that it was the ceiling of the 1st floor not the one we were on that I was talking about.  There were conduits in the floor so it couldn't be done but still the looks on their faces for the floor and ceiling cuts were priceless ;) .  Predicting the reason it couldn't be done just added to the reputation.  It's good to be the King  :laugh:

As a side note when the place shut down the one boss (in the example above) transferred elsewhere and wanted me to go with him, for various reasons I couldn't go.  The other is now my boss (he used to be my bosses boss).  My "genius" is among the reasons he wanted me as his employee again.

I could tell the story of two co-workers slagging me off just out of my hearing when they were missing one fact, sometimes I can read lips.  I don't think they ever figured out how I knew.   :angel:
