Thomas Chrapkiewicz – Silicon Valley History
Chrapkiewicz takes us on a history of Silicon Valley.
Namir Shammas – Polynomial Roots by Optimization
Shammas describes several methods to obtain the roots of the following polynomial equation:
p(x) = x^n + a_(n-1) * x^(n-1) + a_(n-2) * x^(n-2) + … + a_1 * x + a_0
where a_i are all real coefficients.
