Keith, please stop using innuendo to try to discredit
me. My hypothesis does NOT apply to instantaneous values,
never has applied to instantaneous values, and never will
apply to instantaneous values. Please cease and desist
with your unethical innuendos.

If you have to stoop to lying about what I have said,
you will only discredit yourself.

My hypothesis is correct for average values of powers
and *applies only to average values of powers* just as
the irradiance equation from optical physics applies
only to average power densities. To the best of my
knowledge, there is no such thing as instantaneous
irradiance.

The definition of irradiance is the "average energy
per unit area per unit time". Any deviation away
from "average energy per unit area per unit time"
when discussing what I have said is a straw man
diversion, not in the spirit of a good will
discussion.

The definition of irradiance, according to NIST, is power per unit area.
The standard units are W/m2 or lumen/m2.

You can add average, peak, instantaneous, or whatever you like to
further define your quantity of interest. Such additions, however, are
not part of the standard definition of irradiance.

Exactly how much power can exist in a zero unit of
time?

You previously objected to things that don't match
the real world. Instantaneous irradiance would rely
on an infinitesimally small amount of time, something
that doesn't match reality very well. One would think
you would therefore object to the concept of instantaneous
irradiance since it cannot be measured in reality and
exists only in the math model in the human mind.

Still spinning the words, huh? Do you really think that "time-averaged"
and "zero" time are the only possible choices?

Do you disagree with NIST?

Could be that NIST didn't consider the fact that someone
could stupid enough to believe in a non-zero irradiance
averaged over an instantaneous time period of zero. :-)

Official Notice: For the purposes of my postings, I am using
Hecht's definition of "irradiance", i.e. "the average energy
per unit area per unit time".

Cecil must have flunked calculus. Also, differential calculus is
the life-blood of classical electromagnetic theory. The ancients used
it liberally. Cecil probably doesn't believe in speed, because speed is
also an instantaneous quantity. Maybe he can use his argument on the
next ham-fisted Texas trooper who stops him for speeding on his motorcycle.

As energy per unit time is power, Cecil`s definition agrees with what my
dictionary says:
"Irradiance-The incident radiated power per unit area of a surface; the
radiometric counterpart of illumination, usually expressed in watts/cm,
squared."

This is different from Poynting which uses instantaneous values.

Richard, your newsreader dropped part of what I
wrote which was:

per unit area per unit time".
