I made it to page 22 before I found glaring errors in Mr Rollins'research. Some people might call it nitpicking BUT I am a CT tech and it irritates me to have someone talk about CT and then describe a MRI machine. CT scanners do not clank, the sound is a whirring noise that the x-ray tube makes as it rotates around the scanning bed. There are no magnets involved in CT--the CT is a modified x-ray machine designed to take a volume of information and convert the data to images showing the inside of the body. The error is akin to having a fictional surgeon using a rib spreader to do an appendectomy.
