A joke for you.

Q.) How many aspies does it take to screw in a light bulb?

A.) The incandescent light bulb or incandescent lamp is a source of artificial light that works by incandescence. An electrical current passes through a thin filament, heating it and causing it to become excited, releasing thermally equilibrated photons in the process. The enclosing glass bulb prevents the oxygen in air from reaching the hot filament, which would be otherwise rapidly destroyed by oxidation. Incandescent bulbs are also called electric lamps, extending the use of a term applied to the original arc lamps, and in Australia and South Africa they are also called light globes or more commonly light bulbs. A benefit of the incandescent bulb is that they can be produced for a wide range of voltages, from a few volts to several hundred volts. Because of their relatively poor luminous efficacy, incandescent light bulbs are gradually being replaced in many applications by fluorescent lights, high-intensity discharge lamps, LEDs, and other devices. While conversion of electrical energy to light was demonstrated in laboratories as early as 1801, it took more than 100 years for the modern form of electric light bulb to be developed, with the contributions of many inventors. The invention of the light bulb is usually attributed in Britain to Joseph Wilson Swan and in the United States to Thomas Alva Edison and his assistant Barbera. Edison was the first to market the device successfully. Alexander Nikolayevich Lodygin independently developed an incandescent light bulb in 1874. Many others also had a hand in the development of a practical device for the production of electric light.

Interesting joke. I never went THAT far, but I got it. Still, I don't believe you answered the question! BTW I HATE flourescent light bulbs. There is ALSO a ballast problem that can occur that causes a pulsating light and/or a hum, that I would think most Autistics would hate. *I* do! Luckily, either I have become less sensitive, or most places don't have that problem anymore.

In true form the original question must be forgotten.

(it is 1, btw)

Great Joke! By the way, UV lights bug the crap out of me too! I can't even go into some shopping areas/stores that have UV bulbs. I wear my sunglasses, but they don't help much! (The lights make me a little sick to my stomach, and increasingly irritable the longer I am under them) Question: What lighting doesn't flicker? (Not a joke, really asking if you know)

Well, incandescent IS better! You're right, it DOES flicker a bit, but I don't think it is anywhere NEAR as noticeable. BESIDES, this is why they have sinewaves. ALSO, US lights are likely to not flicker so much, because the power cycles 20% faster than in most other countries! If other things flicker out of sync, the flickering will be less obvious. So you want a high refresh rate on pictures. EVEN LCDs flicker. In fact, the standard osscilation for LCDs in the US at least USED to be 50 hertz(in theory, that could make them look worse in Europe where the POWER is also 50 hz!

BTW I can not STAND NEON! Florescent comes in a distant second. THEN you have mercury! I STILL think incandescent are best.

Steve

Well there are two answers to your question.

Do you want to know what lighting flickers too fast for the human eye to perceive or what lighting doesnt flicker at all?

Because there is a significant shortage of the latter type. Light emitting diodes and chemical luminescence (glo-sticks and the like) are about all that come to mind off the top of my head.

Well, Aparantly, the autistic eye can perceive more than the human one.

Anything that uses alternating current should flicker, LED's are dc same with the lights in your car. Not sure where you would find an incandescent for your home that would be dc, it would need a converter which is not very efficient, maybe something used in a motor home might be dc though.

I don't have flicker problems but I wish there where glasses that filtered whatever part of the florescent spectrum is so dam annoying.

Interestingly... Autists are not humans.

I always thought I belong to the Homo Sapiens Autisticus Aspergensis.

I was just poking fun. That is why I added the after it.

theman,

ACTUALLY, incandescent bulbs CAN run on DC, and most DO!! !! Earlier, EVERY car bulb was incandescent, and ALL car bulbs ran on DC! As for LEDs running on DC? In many cases in homes, they run on an intermittant DC. You need capacitors to ride out the short period in between. You COULD do the same thing with incandescents, although you would need a larger capacitor due to the larger current draw. I'm not sure how that would affect the life of an incadescent bulb though. You would get more light, and it would burn hoter, but there would be less cycling. Life is determined by temperature and cycling.

Any of you who liked that joke should read "The Da Vinci Cod" By "Don Brine" (that's a silly pseudonym). Its, as I'm sure you would expect, a parody on "The Da Vinci Code" but it is written to sound as badly written as possible.

There are a lot of places where he goes off on tangents like that. For instance, when he first describes the setting of the story he mentions Trafalgar Square, and remarks that it isn't in fact a square but a parallelogram. He also makes fun of many words. For instance, at one point he says something like "The exterminator had no compunction about killing. To compunct at the correct moment was out of the question".

BTW, the answer to that joke was pulled directly from Wikipedia - intro and history of.

And somehow, that makes it even funnier! !!

oye vey.

Hehe nice. I like that one.

I will check this out.I love word play....is he British?They seem to have a real talent for this..(thinking particularly of Douglas Adams and Monty Python...two nerd staples of humor)

I like the joke ,also.

I don't know if the author is British. I remember the "about the author" section said that he was an English professor, and I think his real last name is Roberts, but other than that I don't recall anything about him.

Speaking of Monty Python, I've always wondered why so many people like the lumberjack song so much. Over the past summer, I was on vacation visiting an uncle who didn't stop singing that song for almost a week, and I heard that he had been singing it for at least a week before I arrived. If it were just him I wouldn't think anything of it, but I have heard a bunch of other people (it seems especially the math/computers type) seem to go crazy over that song. While I thought it was kind of funny the first time I heard it, it lost its humor after about the second or third time hearing it an then it became just boring to me.
