Oh, she was a pip. Much like Dave Hawkins in that she was astoundingly ignorant and bullheaded but somehow incited people to post great refutuations and explanations.
We did finally convince her that at least in theory isochron dating works the way it is explained at talkorigins.org. But she was an old-earth-young-life creationist.

This is an open forum area for all members for discussions on all issues of science and origins. This area will and does get volatile at times, but we ask that it be kept to a dull roar, and moderators will intervene to keep the peace if necessary. This means obvious trolling and flaming that becomes a problem will be dealt with, and you might find yourself in the doghouse.

Some of you might recognize it from High School, but its still a good lesson.
If you divide both sides by (a-b) you get a+b = b.
It seems as if you can do divisions, right up to that point, then the operation can become a nonsense.Last edited by rwatts; 02-08-2015, 10:04 PM.

This one's got a lovely bit of obfuscation to it. I dig it.

Looks to me like, in the 4th step, you divided through by zero (that is, if a = b, a - b=0. You divided both sides by (a - b). Can't do that.)
