An example of Lamarack evolution is, of course, memetic evolution.

Is that evolution? Is a meme more like a (benign?) virus than a gene?

When will we progress to Limerick evolution through Kevin's quantum

" If the Earth moves with respect to the microwave background, it will
be blue shifted to a higher effective temperature in the direction of
the Earth's motion and red shifted to a lower effective temperature in
the direction opposite the Earth's motion. "


Sure, but when discussing the CMB, we assume that such effects are
corrected for. They would rather have to be, considering that the
temperature variations have been plotted to 0.001 K or less.

That's the point.
How can we correct if we do not have a universal frame of reference ie the CMB?
Otherwise all frames would be equivalent - which they aren't.

Hence the notion that all frames are equivalent is not intuitive.


How about the frame of reference where the Center Of The Universe is you?

I'd have to move to Paris for that to stick.
And stand very still.

Wiring all those parts will be the hard part. If
your electronics is up to it, you should at least
consider using the Maxim 7219. It is a 24 pin part
that directly controls 64 LEDs.

Would you mind posting whatever design you decide
to use?

The MAX 7219 data sheet is at:

This is so stupid it's ludicrous.

Don't know

That's typical government wisdumb for you. Make laws based on hysteria.

Banned? Perhaps from use as a general solvent in assembly areas, but if you walk

Toluene is one of the aromatics that is NOT carcinogenic. From the ATSDR
web site:

That was the reason used when it was banned here, merit notwithstanding.

working for some reason. So to reply to an email, just copy the person's

go directly to the person instead of through spammotel's servers.

Also, you probably want to remove the spammotel header info from your

Personally I'd love the whole thing to be on a CDROM because I have
to move lodgings from time to time and books account for about a
third of the mass. Possessions become a millstone sometimes.

I found a Deja-Vu format scan of The A of E which allows me to
archive my paper copy, but it isn't great quality scan and I don't
have time to OCR and format the lot.

What's a Deja-Vu format scan, and where did you find it?

I think the stuff that changes over time should be put on line.
e.g. the list of preferred commonly used parts.

That's a good idea, but it assumes we'll keep it up to date. <sigh>

I'd like excess room (margins) on the pages to write some notes. This shouldn't
cost all that much in terms of editing time, of course, but it will cost paper.
There's an example which illustrates exactly what I mean as well as another idea
-- adding selected comments from students who have used sections of earlier
versions on similar topics -- in the book from Graham, Knuth, and Patashnik
called "Concrete Mathematics: A Foundation for Computer Science".

I used the stuff quite a bit when I was a kid, and I'm just fine (I

Carbon tet was used in the dry cleaning industry in the early 20th
century. People worked over open vats, breathing the fumes all day
long, and it took about 20 years of exposure for harm to be done. It is
an excellent solvent for general purpose cleaning. I'm sorry it was
banned.

I used in the TV service business back in the olden days and I'm
perfectly n..n..n..normal, just like Roy.

On the other hand, some people would say this explains a lot.

Don't Sweat it. You have an internal Voltage Regulator that supplies the
camera with what it needs. The higher voltage PD is only to insure the
voltage regulator remains stable and batteries get a good charge. There
are many different arrangements so to insure you dont do any damage limit
your voltage to an adapter rated 5V or less. Even if you use the proper
voltage unregulated adapter you will still get about (4.2/.707) 6V to the
camera.

I'm ok with that. I just need to level shift a drop WRT the rail up
