We were privileged to have James Hannam with us in November of 2012 to speak on “Faith & Science: Reclaiming Christianity’s Scientific Legacy.” Unfortunately, we had some technical issues with our recording equipment that evening, which prevented us from taping his talk. Upon learning of this, James very graciously agreed to re-record his presentation for us. While this recording necessarily lacks the immediacy of the live event — and doesn’t include the Q&A session, which was stimulating and engaging — it does capture the content of his presentation, and we are grateful to him for producing it. Enjoy.
