In his book The Ascent of Science, Brian L. Silver states "The order of increasing nuclear charge was, with one exception, identical with the order of increasing atomic weight."
What is that exception, and why?

We present new spectroscopic observations of an old case of anomalous redshift--NGC 7603 and its companion. The redshifts of the two galaxies which are apparently connected by a luminous filament are z=0.029 and z=0.057 respectively. We show that in the...
f(x) = (1 - x^2)^1/2
This all stems from me approximating pi by numerically evaluating the integral S f(x)dx from 0 to 1 and multiply the sum by 4.
Now...
Would you agree that f(x) has a derivative
f'(x) = (1 - x^2)^-1/2 * -2x
?
According to my textbook this is so. Now I can...
