I consider myself to be a gentleman scientist, by which I mean an amateur with broad but limited education and experience in many spheres. I have primary degrees in Computer Science and Psychology. I have Masters degrees in Cognitive Science and Machine Learning. I spent over 40 years in IT and started programming with punch cards and recently programmed a Quantum computer.
As a scientist, I believe that it is important to be sceptical and to question even basic assumptions. Of course, grumpy old men share this trait.
It is now time to question whether negative numbers should be part of our number systems.
