I did use scientific notation.

Scientific notation is not exclusive to the metric system.

I did use scientific notation.

Scientific notation is not exclusive to the metric system.

Did you use scientific notation in home economics?

When you took home economics, were the primary measurements in metric
units?

How often did (or do) you cook something using one tenth the
quantities called for in the recipe?

Again, an absurd claim that posters here have "never" done arithmetic.

How about this: Some posters here find the metric system wanting. They
don't buy the religious hype that it is oh so much better than
imperial units.

The metric system often does not result in more convenient numbers on
a human scale in the real world.

The first step in using arithmetic for something useful (rather than
as an academic exercise) is to have numbers that represent something
from the real world. Those numbers come from counting or measuring.

Are you claiming that counting is easier in the metric system?

Adding 20 eggs + 16 eggs = 36 eggs is arithmetic.

The unit conversion from 36 eggs to 3 dozen is not arithmetic. It is
dimensional analysis and the application of a conversion factor. The
arithmetic in that conversion is incidental.

The metric system is not devoid of conversion factors.

Back to your focus on arithmetic. We need numbers on which to perform
that arithmetic. Assuming you are not saying it is easier to count in
metric, are you saying it is easier to measure in metric?

We're back to Benford's law:

The metric system is tailor made to run afoul of Benford's law:

http://en.wikipedia.org/wiki/Benford's_law
real-world distributions that span several orders of
magnitude ... are likely to satisfy Benford's law
to a very good approximation.

The metric system is intended to span *all* orders of magnitude. Thus,
measurements near 9x10^n meters should be relatively rare.

http://en.wikipedia.org/wiki/Benford's_law
if one converts from e.g. feet to yards
(multiplication by a constant), the distribution
must be unchanged

That is, if one converts *all* measurements from feet to yards,
Benford's law will continue to apply.

But *not* if one only converts measurements to yards *only* when
distances expressed in yards are more convenient than distances
expressed in feet.

If one uses units that are scaled to the measurement (inches, feet,
yards, miles), they will be using a more diverse mixture of numbers.

How many meters in a light-year? Or a parsec? Tsk tsk. Those aren't
nice round multiples of a meter. Why is no one hammering on the
astronomers to get with the program?

Dumb how?

Is not one of the claims for the metric system is that it is a more
natural system of measurement because we have 10 fingers?

Do you have so much trouble thinking outside the box of a chemistry
lab?

Which chemistry labs? You referred frequently to high school
chemistry.

Are you saying the metric system was conceived for the benefit of
industrial chemists? Are there no industry-specific units of measure
which industrial chemist find to be more useful than metric units?

Is chemistry the only pursuit that matters? Why should the entire
world adopt a system of units that is convenient for chemists when it
is less convenient for those who are not chemists?

What? No examples of the wonders of the metric system in home
economics where you took your slide rule to class and used scientific
notation?

Narrow-minded scoffers who speak in disingenuous, moot quips have an
exaggerated view of their opinions. And often lack the class to admit
when they were wrong.

Perhaps Uncle Al has had an influence on your posting style. Your
posts seemed to be of higher quality years ago. Now they often contain
slaps constructed with half a thought.

Being like Uncle Al is a two way street. You need to bring a lot more
horsepower to the table to make an emulation worth reading.

Well, two months of 100 degree highs here in Austin will
unman about anyone. (It's darn difficult to brew decent
beer when the amient tempurature kills brewers' yeast.)

On the other hand, I know at least
one person in the Century Club for having survived 100 C
in a Turkish sauna.

This is still the first time that I ever heard "white-guilt"
associated with the metric system. Y
You still haven't explained to us how the metric system relates
to "white guilt" or "the left." In fact, I don't precisely understand
what you mean by "the left." Most people relate "the left" to
socialism. You seem to relate the "left" to blacks and Jews. Most
people relate the profit motive to "the right." You seem to think that
the profit motive to the Jews, not "the right.
After the French revolution, the legislature was divided into
the left and the right. At the time, it literally referred to the
geometry of the room. The left side was associated with violent
extremists, the Jacobians. The right side was associated with the
"profit making" group. I don't know if there were ANY Jews on the
right side, but the right definitely liked profit. From your posts, it
seems that you think of yourself as a modern Jacobian.
It is amusing that you like the French revolution and dislike the
metric system. The metric system was created because of the French
revolution. There were no Jews involved, so far as I know.
For your information, the Jacobian movement collapsed. Their
ideology was unworkable. The metric system has survived long after the
Jacobians have disappeared. You would know this if you could read.
