They have to have a doctorate or a masters, or your not really allowed
to publish in most refereed journals, unless your a student working
with a PhD..


One of the huge mistakes in academia. Right up there with universities
and colleges not allowing practicing engineers to teach because they
don't have the "proper credentials".

My system is mostly for lighting, with possibly a laptop and a portable

I use draw 1 amp each. So far, the most I have on one circuit is 2 of them.
For minimum voltage drop, I wire my interior circuits with #10 THHN wire.

That is part of where the AGW crowd got started. One guy gets a
theory, and publishes 'proof.' The next guy looking at it says,
"Well, the part in my field is all ca-ca, but this other stuff looks
compelling..." and so supports his collegue. The other guys, in the
other fields, all feel the same, but still support the original
premise since they can't refute the stuff outside their own field of
expertise. Also, since that second guy supports it, the stuff in his
area must be right...

How would one go about powering a laptop from a 12VDC supply? DC-DC
converter? The only things I would likely power from PV would be lights,
computers (laptops) and a fridge.

And your undergraduate degree must have come from a college known as a party
school that slackers attend to just squeak by without actually learning
anything too. :)

If you started offering, e.g., week long design classes to industry I'm sure
you'd get plenty of takers. (Same for Win and Phil and Joerg and
others...) -- the going rate is ~$300-$500/day/student, which appears to make
it worthwhile for all involved if you can round up at least 5-10 students.

It's particularly silly in the humanities. At one time, we expected
professors of English and philosophy and so on to be _learned_, i.e. to
actually know their subjects forwards and backwards.

At Oxford and Cambridge, English degrees were only introduced in the
1920s, and the requirements for a BA in English included being able to
read and write the English of all periods, including Anglo-Saxon and
Middle English. That went away in the 1960s, I think, along with a lot
of other good stuff.

Then the humanities got the 'originality' bug, which has been a huge
disaster for learning in general--you don't get tenure for agreeing with
your predecessor.

In engineering, the basic professional qualification is a bachelor's
degree, whereas in science, it's a doctorate. The narrow specialization
of Ph.D's in engineering is not typical of most scientific disciplines
IME. The skills are just different. I was fortunate to have a brother
who taught me how to solder at age 10, but then I went and did physics
and astronomy and math and all that stuff--I've never taken a circuits
course in my life, unless you count the jokey
RLC-circuits-for-scientists class they made us take as sophomores. (I
could have taught that course at the time.)

Spending 20 years at school won't make a fool into a wise man, but if
you have a few brain cells to rub together to begin with, it isn't
always wasted. ;)

Yep, MIT is well known as a party school. When I was a student, the

DU in a *bomb* would be pretty pointless, if you stop to think about it.
From Wikipedia: "Depleted uranium is used as a tamper in fission bombs
and as a nuclear explosive in hydrogen bombs. It is a potential
containment material for a Nuclear shaped charge due to its opacity to X-
Rays." (http://en.wikipedia.org/wiki/Depleted_uranium)

Depleted Uranium _is_ used in some ordnance rounds (most famously tank
rounds), and if the person in question is "relaxed" with her usage of
military terminology, that may be what she was referring to.
