Hello everyone, newb member here but been loving Physics Forum for quite some time. I'm an Australian biologist with chemisty/earth sciences/psychology co-majors at uni in the 70s and 17 years research experience mainly in neuroscience in medical schools. Bit of tutoring, bit of plant physiology and marine ecology thrown in. Loved physics at high school and would have become a physicist, but too much maths lost due to illness. I'm 're-learning' physics as it is now in the 21st - big changes, exciting time to be alive!
