Right, Nottale's ideas haven't been accepted by the physics community. It's interesting to think of why.

I have the impression that, while having some good ideas, Nottale promoted his ideas in unorthodox ways that other scientists didn’t like, and pushed his ideas too far to include too much. I guess that, if Nottale had limited himself to publish specific results and small steps in top physics journals, his ideas would have been better received.

I guess Nottale's ideas are not entirely right. But we can say the same of *all* current scientific ideas. Given that all scientific theories are wrong and will inevitably be replaced by better ones, I think part of the value of a scientific theory lies in its ability to provide starting points and mental models for further research, and I think Nottale's ideas are valuable in this sense.
