Ok, I apologise for asking this very basic question, but I haven't found a simple answer anywhere.

Once again, I am sorry if this is a rediculous question.

And some 40 posts later the discussion is still going on and
no definitive answer as to what causes the effect has been
agreed upon. That is how elementary and ridiculous the
question was. 🙂

As some earlier poster said, there is no need to apologize
or assume a question is ridiculous. Some of the seemingly
most stupid and elementary questions (where I would not
include your question) are actually not trivial at all, but rather
so elementary that almost nobody has bothered to think
about them.

SY is this a personal insult? I can't tell....

"that's why I wasn't surprised that you couldn't find the right answer."


It's responses like this that make me so eager to get in the middle of nonsense like this. Why try to discuss anything just to argue with idiots with a chip on their shoulder. Why try and educate someone who has no desire to learn anything. maybe I should just Email answers to people with questions to avoid having to deal with moronic post like this.

my thoughts exactly when I was replying to your posts.

Who said different minds don't think the same?

All the same

Just for fun, I took the lid off of my amp and drove it with a highish input signal and no load. The input signal was just audible from the MOSFETS with my ear up close. Without a load it is not particularly loud. The only interesting thing is that I replaced two of the transistors a couple of months ago. All four of them are producing the noise.

I did get someone else to listen to it as well, they found it difficult to identify the tune (tinny, high and very quiet), but it was there. I wouldn't expect it to replace my speakers!

I would also like to thank everyone for their opinions so far, I never dreamt that this would attract so much attention.

Russell and Whitehead showed that, indeed, this is a deep philosophical issue. It's amplified a bit in Courant's "World of Mathematics."

Remember the line in Videodrome: "They have something much more dangerous than that. They have a philosophy."

I am not so sure there was anything philosphical in there,
unless millwood made a typo. You cannot prove whether
"1+1" since this is not a statement. You can calculate it,
but you cannot prove it. Perhaps he meant
proving whether "1+1 = 2", which is or isn't true depending
on our choice of algebraic system. For the usual algebraic
system it is elementary and follows from the Peano axioms.

I'm looking for a third party opinion, as I don't believe what I see.

Yes, I didn't mean there was something wrong with it. You
report it as a member, not as a moderator, to the moderators.
I just thought is sounded a bit fun that a moderator reports
to the moderators, but it's late and I'm tired, so it probably
wasn't as funny as I thought.
