Partial Sums
The nth partial sum of the diverging harmonic series,
is called the nth harmonic number.
The difference between the nth harmonic number and the natural logarithm of n converges to the Euler–Mascheroni constant.
The difference between distinct harmonic numbers is never an integer.
No harmonic numbers are integers, except for n = 1.

Famous quotes containing the words partial and/or sums:
“The only coöperation which is commonly possible is exceedingly partial and superficial; and what little true coöperation there is, is as if it were not, being a harmony inaudible to men. If a man has faith, he will coöperate with equal faith everywhere; if he has not faith, he will continue to live like the rest of the world, whatever company he is joined to.”
—Henry David Thoreau (18171862)
“At Timons villalet us pass a day,
Where all cry out,What sums are thrown away!”
—Alexander Pope (16881744)
