"The Corona Simulation Machine: Why the Inventor of The “Corona Test” Would Have Warned Us Not To Use It To Detect A Virus
“Scientists are doing an awful lot of damage to the world in the name of helping it. I don’t mind attacking my own fraternity because I am ashamed of it.” –Kary Mullis, Inventor of Polymerase Chain Reaction."
This is a long but good read about the invention of the Polymerase Chain Reaction (PCR) test. You will get a good idea of what this test tells you and what it does not tell you. It also discusses a gulf in medical philosophy. Highly Recommended!
