If we combined what we are learning about energy, possibility, probability, and dimensional space time (particularly on the smaller scale) etc from quantum physics and mechanics with what we are learning from neuroscience (particularly in microbiology) we could discover all kinds of interesting things physiologically. It could be most beneficial medically as well as understanding our mind's relationship with the universe. I personally think it would lead to whole new scientific fields. It may definitely lead to new knowledge and technologies that revolutionise our current world.
If we applied that knowledge into useful technology, a computer that you can think at would be a little more possible. One of the problems facing mind reading computers is that every person's mind is configured differently to other people's minds. However, that can be an asset rather then a draw back. When a new person is using a new computer, they could program it to recognise their personal brain print with the basic alphabet and numbers, sort of like choosing the configuration of your personal home page. Any new users could do the same. It could be used for security purposes. After all, who else has your personal brain print. As well as being useful for all sorts of tasks, it could greatly benefit people who have difficulty using computers, such as quadriplegics.
That's a musing, however, I really do think if quantum physics knowledge was combined with knowledge about neurological impulses of the brain, some useful understanding could occur, and if tested and applied, could be most beneficial. I need to do more research to more clearly express what I'm trying to say.
