Earth science..I am fascinated with how a simple rock on the outside, when cut down the center, turns out to be the most beautiful and most exquisite crystal/marble or simply a precious stone on the inside!
It teaches you to never judge a book by it's cover...or in this case how to appreciate a simple rock for you never know what may turn up on the inside nor how precious or valuable it may be.
neuroscience, anatomy and developmental biology. Sorry, couldnt decide between the three - they are what I have been studying for the past five years.
biology, they always find something new, there are so many life forms that we dont even know of still!
i love the periodic table if u do try out periodictable.com or
