I have a good friend from HS,now in Pittsburgh, who developed the testing algorithm used to identify remains from little more than dust.
Never was able to best him in math or science no matter how hard I studied. And his younger brother
is even quicker,
He testifies in Courts around the country and has helped with the Towers etc
