I have been following for years amazing concepts certainly worth the time top marks great

excellent , the content will get you thinking

Isaac has such a unique and inciteful way of thinking about and explaining some difficult concepts. His episode on the machine rebellion blew my mind. I've had so many, oh yeah, of course that makes sense moments listening to him over the years. Fantastic stuff!

The best science show on the Internet

I follow this gentleman of YouTube and have today found him on Audible. Just the stuff to listen to when the children are absent and either painting models or building IKEA units :-)

Always a joy to listen to.

I have been following SFIA for years now and the depth of coverage into topics which are frequently glossed over in modern science fiction (and science, for that matter) is just fantastic. Keep up the great work Isaac!

Pure Brilliance
