Without science advancements we would still be living in a cave with a life-span of 21 years .

And where would we be if we did not study History?

When we create the time travel machine we will LIVE history , not study it !Scientists and mathematicians work in abstract and theoretical planes. Historians work with past occurrences of fact and their studies still do NOT prevent a repetition of similar events in future times .
In reality, " the strong will go to the stars and the meek shall inherit the Earth ."

Here's a great Science-History URL for you .

Merry Christmas !!
