Your file cabinet has a warranty?
Boy, you don't remember stuff too good, do you?

A brain is like a file cabinet: it can only hold so much, so file the
important stuff and recycle the rest.

[quote:78c90540cf]They were whisker types - not PN junctions.
Ge had most - as it was high frequency and Si wasn't.
Yes there were PN diodes but mostly whisker - in the late 50's.
Limited use and not for high rel at all.
Consider the 3 transistor radio - bound to have something in it.

I brought an error very like that around here a while back. I had to
eat it. Search for it.

First, Si diodes were not used in WW II. The PN SI diode wasn't invented yet.
Nearly all the radar first mixer diodes were silicon point-contact
types, essentially silicon schottky diodes.
See the MIT Rad Lab book, volume 15, "Crystal Rectifiers" for a bunch
of WWII (and pre-war) stuff about diode development. This is from that
book:
ftp://jjlarkin.lmi.net/RadDiode2.JPG
ftp://jjlarkin.lmi.net/RadLabDiodes.JPG
Selenium wafers and sticks were the power types
and point or whisker diodes for RF. [ I have some of these in lead cans ]
In the 60's it was still that way.
Funny, I recall using lots of silicon PN diodes (and SCRs, and
transistors, and tunnel diodes) in the early 1960's. Tek was using
GaAs diodes in their sampling scopes ca 1964.
Silicon diodes were developed by bell labs for internal telephone use
but semiconductor had to be invented first.
No. See the RadLab book.
Look at the date of the transistor. Silicon diode and Germanium diode.
I know Radar in B52's were using Selenium and Germanium for RF.
Selenium was never used in RF or radar, except maybe power supplies.
Far too slow.

Geez, no wonder you're having trouble finding a divide-by circuit.
I commented on your _statement_ by asking a question.

My brain would beg to differ here. I remember _everything_, unless
I'm in a blackout drunk state, which I don't do very much any more.
And I'd claim that there's no theoretical limit, since "memories" and
stuff aren't held in some finite file cabinet-thing, but are stored in
patterns of synapses; you don't grow any new neurons, but there's no
known limit to the number of synapses you can grow - oh, yeah - we make
new synapses everything something makes an impact on us - I think the
expression of emotion releases hormones or enzymes or something that
stimulate synapse growth.
Ever notice that you remember stuff that was a big deal at the time, but
not mundane stuff, like what you had for lunch last week? :-)
You remember your downhill run - do you remember the T-bar ride just
before it? ;-)
Cheers!

I read about some people who remember everything. It's more a curse
than a blessing. One guy says that the slightest input - a name, a
sound, a number - unleashes a flood of memories that can be
overwhelming.
There are lots of things better off forgotten.

Boy, you don't remember stuff too good, do you? I took a picture of
them stuck to my file cabinet, posted it on a.b.s.e, and you said that
I'd voided the warranty. I asked, "What, by not cutting them in two?"
because you had mentioned being able to separate the saying from the
logo and address & stuff. You said, with much indignation, "They're
_REFRIGERATOR_ magnets!" (I don't remember the exact level of emphasis,
but it _was_ emphasized! )
I can't quote chapter and verse, because google doesn't archive alt.,
which I don't get any more anyway. )-;

You might try Internet replayer, it archives some of a.b.s.e. |

Unless you have memories of actions which you'd like to forget, why
would you say that?

Like history, so you can make the same old mistakes over and over and
