Re: Iron wire inductor

Hi, You can break this down into two or more separate questions. The first question is what happens when we try to use iron for wire. The first thing we notice is that the resistance is much higher than with copper wire. That is a deterrent, but maybe you can get away with it. The second thing is th...

Re: Microwave oven transformer... reversed.

I dont think he should remove the welds holding the core together just to put in 2 turns. I'd cut out the secondary winding with Plato wire cutters or a knife. Then feed through the new secondary. I once made a twelve Volt power supply that was resistant to damage from shorting out the 12V. It had ...

Re: What keeps me up late!

Possibly...since I live in the basement I don't really know how many suns old I am! The way things are going, future students will have it easier since there won't be any history to study. Does burning books from the 30's sound way too familiar? Hi, Oh yeah, that is an interesting view. Get rid of ...

Re: What keeps me up late!

That's ok Al, I understand what happens to us after too many sunrises :???: Hi Len, Are you suggesting that we can live longer if we can somehow prevent that darn Sun from rising and falling so darn much? :-) I agree, lets start a petition to take down the Sun ! After all it was there during the Ci...

Re: Effects of loss of analog TV broadcasting on viewing

Hi, Can not help but agree with most of that. The simple answer is that the Politics are no longer for the people by the people, it's for the politicians by the politicians. This is very clear to me now because i hear some of them state that things to go after do not amount to what is good for peopl...

Re: What keeps me up late!

Hi,

Looks like this thread went down the rabbit hole :grin:

Worm holes require too much energy to produce anyway.

A black hole is just Nature's solution to the problem of too much mass in close proximity.

Ok bye for now...uhg, uhg...<sound: cave door closing> :smile:

Re: What keeps me up late!

A mirror is different because more of the light is reflected, but even in a mirror box the light would be partly absorbed and turned into heat, and the place where it is emitted would most likely end up absorbing more. And so...if it is absorbed by the emitter I guess it could also be 're-emited', ...

Re: What keeps me up late!

Hi again Len, I like these questions they are kind of fun to think about. You seem to be good at generating them. The question of where the light goes is really easy to answer if we take it seriously. Whenever light strikes an object the wave function breaks down and something changes it. This happe...

Re: CFL vs. LED Light Bulbs

Hi, The thing about LED bulbs and CFL bulbs is that they have some color variance. This means it is best to try one model and if you like it stick with it, and if not go to another model. A guide would be that 5000k bulbs are like natural light, and 6000k bulbs are a bit more blueish, but you never ...

i Len, I am not sure what you are trying to say about the lightening....

As to the 'lick' factor.... I'll ...

Re: What keeps me up late!

Hi Al... Just a few comments back... Ans: Lightning travels faster than sound, so we see the light flash before we hear the thunder clap. The sound wave arrives after the light wave because sound travels slower than light. The distance to the lightning strike can be calculated this way by timing th...

Re: What keeps me up late!

The original questions repeated with some answers... If, you could travel faster than the speed of light, could you go somewhere, stop, turn around, and watch yourself arrive; and, if you traveled faster than the speed of sound, would it likewise arrive after you? Ans: Lightning travels faster than ...
