We're agonna see why it was that negroes wrote so many spirituals 'bout heaven. It's 'cause life down here can git hard at times. Judgment's acomin'.

Well, I don't know the details but I do admire the symmetry and the depth beyond our comprehension.

The Great Mathmetician must have a chuckle over all the problems we say cannot be done that sit before our very eyes each day.

The interesting thing is that

log(-1) = pi*log(e)*i

Why do we get pi and and Euler's constant, e? This mysterious world of mathematics!

Mr. Owl says:

The logarithm function can be extended to the complex logarithm, which applies to negative and complex numbers and yields a complex number. The value is not unique though, since for example e2πi = e0 = 1 which implies that both 2πi and 0 are equally valid logarithms to base e of 1.

When z is a complex number, say z = x + iy where x and y are real, the logarithm of z is found by putting z in polar form that is, z = reiθ = r(cos θ + i sin θ), where r = |z| = sqrt(x2+y2) and θ = arg(z) is any angle such that x = r cos θ and y = r sin θ. The function arg is a multivalued function.

If the base of the logarithm is chosen as Euler's number e, that is, using loge (denoted by ln and called the natural logarithm), the complex logarithm is:

log(z)=ln|z| + iarg(z)

which is, just like arg, also a multi-valued function. The principal value of the logarithm, Log (denoted by a capital first letter), is a single-valued function.

Therefore, the principal value of the logarithm of a negative number r is:

Log(r) = ln|r| + i(pi).

Any dummy should have known that!

That was wonderful...I know just how they feel, and I've seen that same look in the eyes of my own grandkids.

Talk about KJV-onlyism craziness - what about burning all other versions of the Bible:

Believe me, KJV-onlyism is another kind of cult!

Like most dangerous trends it sounds good and profitable to many but lacks prudence and wisdom.

Sound Biblical scholarship has little to do with it. KJV-only people are emotionally tied to the KJV and no sound, scholarly argument is going to convince them no matter who makes it. BTW, the NIV like the RSV is not a bad translation taken by itself - it is only the trends in more recent revisions that have led them in the wrong direction.

It is interesting that more literal translations like the NAS or ESV are not acceptable to these "conservatives" either. Question: do any of these wiki-translators know any Greek, Hebrew, or Aramaic?
