Age of the Earth
"Hey Skeptics, I have a brother who is a born again christian, while I am an atheist. Naturally this leads to some interesting debates between the 2 of us. One thing that keeps popping up is the age of the earth and how scientists KNOW how old the earth is. As an avid listener of your podcast [and have been since day 1] I know that you rightfully ridicule whenever some religious fundamentalist gets the age of the earth wrong; however, I can't remember a time where you explained in simple, easy to understand terms how scientists know what they know with regards to the earth's age. Admittedly I could have just missed it or since forgotten it if you have explained this. If that is the case could you let me know, if you remember, the episode # of the podcast? If not, could you please enlighten myself and anyone else having a hard time relaying this info to the under-informed? Either way, thanks for all your efforts. Big Fan, Jason www.talkorigins.org/faqs/faq-age-of-earth.html"

Magnetic Water
"Hey Guys Found you guys on digg a couple of months ago and I just cant get enough of your earlier episodes - ive found myself worrying about what happens once i reach the start.. Anyways was eating in front of the telly last night and caught a story on TodayTonight about magnetic water. It doesn't appear to be on youtube at the time of writing but heres an article from the TodayTonight site - todaytonightadelaide.com.au/story.php?id=603. Is there nothing magnets cant do? I get the impression that the company behind this (Water For Life) has taken the opportunity to cash in on Australia's recent drought and water shortage which has been prominent in the media for a couple of years now. Would love to hear your thoughts on the matter and the 'scientific evidence' behind it.  Enjoy! Ben Morris Australia  www.csicop.org/si/9801/powell.html"

"'There is no absolute knowledge. And those who claim it, whether they are scientists or dogmatists, open the door to tragedy. All information is imperfect. We have to treat it with humility.'- Jacob Bronowski"
