Roger Penrose is a mathematician who made important contributions to theoretical physics in the 1960ies, for which he received a Nobel Prize. In later decades, he published speculative books on consciousness, quantum physics, and neurobiology. These ideas have been out there for about 30 years now but have not been able to convince scientists in general. Rather, they are generally considered implausible or outright contradicted by the evidence. Simply put: It’s wrong.
The idea that quantum physics plays a direct role in brain function is very much on the fringes of science.
No offense meant. I know these ideas are very important to many spiritual people, but I felt the casual reader should know that it is not important in science.
