BC, Eratosthenes had shown that its circumference was 40,000 km, just by a smart use of mathematics, without leaving his home town of<o:p></o:p></span></p>

been a crucial tool of discovery and understanding.<o:p></o:p></span></p>

last challenge for mathematics: can we control change?<o:p></o:p></span></p>

the situation up to the twentieth century, in the second one on July 17 I will follow up to the present time and the global challenges humanity and the planet are facing today.<o:p></o:p></span></p>
