Hi John,

It's those English electrons that fly on the wrong side of the atom ....

perhaps someone should just say, that electrons do not all march single file,

in an orderly fashion.

'they bounce' wiggle, and vibrate - making noise.

Scott, I purchased my first HP calculator in 1963, when they first came out, and was glad for it. The HP calculator that I purchased at the UC Bookstore was the simplest calculator that I could find with REVERSE POLISH action. I am not good with TI calculators.
You are right, internment was the wrong word, I thought that it meant a stay of time, but it apparently means a FORCED stay of time. Just trying to use the language in a colorful way. I guess 'stay' would be adequate to replace 'internment'.

Hi John,

What HP calculator are you talking about? Are you referring to a hand calculator or one of their desk calculators? I got my first HP-35 hand calculator right after they first came out, while at Bell Labs. I think it was in the mid 1970s. I thought it was their first scientific hand calculator, and it did have reverse Polish.

Thanks,
Bob

Sorry, that was a typo, I can't tell decades apart, anymore. In 1963, I ran the biggest computer in the 'known' world at the time, the IBM 7094. I got into MECHANICAL calculatiors in 1966. Time sharing in 1968, and finally, my own scientific calculator in 1973.

I bought my Gremlin in 1973, quite a car. You once said Jack made his money "overclocking" cars. I remember those days, that and CB radios. I had friends that made extra cash by building illegal linear PA's for them.

Let me clear the air here, so that people do not get the wrong impression.
This is not a scandal sheet, but there are lessons to be learned by people, and that includes many here, who judge an idea or a device without any significant understanding of, or even an attempt to try it. This is commonly defined as 'prejudice' and there has been plenty of such on this thread. Now why does it occur? My impression is that there are multiple reasons, including: Wanting to feel secure in ones previously learned knowledge, a significant cynicism regarding the honesty of others, due to rumors or past experience, and perhaps other factors.
If we are to progress in understanding how to make better audio designs, it is necessary to become aware of one's own 'prejudice' as well as examples of others showing 'prejudice'. Some of the letters cited by others, appear to be 'prejudice' against the statement made by some professional here on this thread. If I could show explicit examples of this, by others, OUTSIDE this thread, we all might gain some further understanding, without inciting each other, and being then accused of insult or defamation of someone contributing here, or who is normally in the audio profession.

there is a protective mechanism of the mind, a sort of 'truth detector'
it compares new incoming informaion with that which has been previously learned.
if the new does not match the old, right or wrong, it is rejected.

Notice the response about Feynman?
new info does not match my belief.
right or wrong... reject !

Let me fix that for you:

"If the new conflicts with well-established and experimentally demonstrated knowledge and is offered without evidence by someone selling something, it is ignored."

Otherwise, you spend all your time and effort on perpetual motion machines, faith healers, and quacks.

and the Wine Tastings


"Things like that happen in Vegas," Arbogast said. "We don't want them happening here."

The Temecula growers were not the first to aim the grapes of wrath at companies driving drunks to their doorsteps.

In Napa County, a number of wineries have simply put out signs announcing: "No limos." Unfortunately, the signs have a tendency to disappear, said Michael Korson, an investigator for the state Alcoholic Beverage Commission.

The Bybee patent application is interesting. I have heard the associated product and it was pretty good. Reading through it they will push back pointing out its similarity to the Elgar power conditioner. I think its similarity to Wetzel's regulator is more interesting.
