Looking at Sensory Disorder as a Physics Problem

I am very concerned about sensory disorder being looked at as a mental health issue rather than, what it actually is, a physics problem. It is a well known fact that the shape and density of objects changes the way they carry sound. Most people are sensitive to the sound of fingernails on a chalkboard. Some people find other sounds so painful it affects their perspective of pain. Looking at the actual physics of the ear should allow scientists to actually understand why this is happening and design hearing adjustment devices to help people hear what they need to hear instead of just hearing noise.
This is a link to lecture notes showing equations to help predict how things will sound.

Time to Revise the Theory of Evolution?

Evolution is often seen as a competitive process, but really evidence may suggest it is really about adapting and sharing your environment. Humans ability to communicate and use their hands allows them to benefit from and help other creatures who benefit them. We are not competing with nature but enjoying the benefit of sharing our environment with plants and animals. Survival is a matter of cooperation, between living species. We are not just the product of our own evolution, plants and animals play a symbiotic role in our lives, not to mention all the microbes it takes to digest our food. We are not fighting life on Earth so that we might survive, but depending on it to help us survive. We have past the point where new territory can be won from outsiders and become one people. Will we adapt to this change or will we continue to fight and disregard life on this planet until there is none? I hope we will understand the value of life and protect it and not forget we depend on it. Survival of the most compassionate, ethical, logical, and inclusive is the revised theory.
