John Curl's Blowtorch preamplifier

Quantum resistors are not absolutely necessary to make quantum purifiers work, but they help. Any ideas why?
For the record, the majority of quantum purifiers that I have on hand and in my audio system, do NOT use quantum resistors, but another resistor material. The best units use the highest Fermi velocity that can be normally obtained. Normal, non-inductive power resistors are 3'rd best.
 
I remember in 1959, arguing with my first college math professor, that the answer to dividing by zero was infinity. (didn't know about limits at the time). The professor said it was 'undefined'. Same thing here, it is difficult to get around new concepts that violate OHM's law, etc., but it is necessary to grow.

If this has something to do with Mr. Bybee's resistors, then the output of a purifier would be also quantized ?
Does this mean, that current noise (as well as all other small signals), which falls below a certain threshold is "eaten up" or modulated into an even bigger amount of quantization noise, hopefully out of audio band ?

For me this sounds like sending the signal through a low resolution quantizer, hoping to get a higher dynamic range, without knowing what the original signal is ... strange thing 😉

So a two node, passive noise shaper or what ? Not really ... :whazzat:

“The entire radio would easily fit inside a living cell, and this small size allows it to safely interact with biological systems,” Zettl said. “One can envision interfaces with brain or muscle functions, or radio-controlled devices moving through the bloodstream.”

the above + http://en.wikipedia.org/wiki/Very-large-scale_integration

could lead to 'music/signals' directed in to living cells
 
Nanomaterials are about to be regulated by the EPA. They could be hazardous. Scott, you should be careful about what you commit to eat. EPA

While I think there is interesting stuff in carbon nanotubes we are only looking from a distance, with little real knowledge of how they work or how to use them.

And discovery's can come from strange places. I have been helping an experimenter develop room temperature superconductors at a distance. He may be completely off base but he seems to know enough about what he is doing that I'm willing to risk some time and resources to push him along. If he did pull it off and I had blown him off when he asked for help I would feel really stupid.

Goodness gracious! Who says John is required to agree with me, or I with him? We agree on some things, certainly, but I suspect that we could easily find a number of things we disagree on if we put our minds to it.
Here, I'll start things off:
I'm afraid the Porsche 924 (that's what John drives, isn't it?) isn't for me. I test drove one way back when and found that the steering wheel rested on my thighs. As I recall, the steering wheel wasn't adjustable, as is so common today. I was afraid that in a...spirited, shall we say...driving situation that I would fail to negotiate a turn because my hand would strike my leg and prevent me from turning the wheel sufficiently.
I believe one of the car magazines of the time (Car & Driver?) mentioned the same thing in a review of the car.
I've got some faint recollection that they may have changed the angle of the steering wheel to make it more user friendly. John may be able to say yea or nay on this, as he's kept up on car-related things more than I have.
Besides, I was holding out for a 911.
Never bought either one, but that's another story.

P.S.: Lew Johnson (of Conrad Johnson) took me for a spin in his 928 once when I was in town. Lotsa fun, but more money than I could justify. Some foolish part of me still wants to buy a used 928, but there's no point, really. Where would I drive it?
