@Palandre,
I have read your "postings". I believe they are idiotic.
I work in technology. It is based on science. If the people in charge of designing semiconductors don't have a firm grasp of Quantum Physics, they will be lost. I work in software and data science. I don't have much use for Physics in my particular job.
But my job is based mathematics. If I don't understand linear algebra and statstics, I can't do my job.
The people who send robots to mars can solve differential equations and have all studied General Relativity. I know this, because I was in these classes in university.
The idea that you can detach technology from science.
By the way 1 + 1 does equal 2
