This video illustrates a proof of the Fundamental Theorem of Algebra: \"Every polynomial degree at least 1 with complex coefficients has a least one complex zero\". Proof: Let P(z)= z^k + a_k-1 z^k-1 + ... + a_1 z + a_0 be any polynomial (in the video P has degree 3). Substituting z=r exp(2πt) we obtain for fixed r a continuous map from the unit circle to C. For the special polynomial z^k the image of this map winds k times around the origin. Using the deformation z^k+λ(P(z)-z^k) we can continuously deform the image of zk into the image... |

Albert Einstein (March 14, 1879 -- April 18, 1955) was a German-born theoretical physicist. He is best known for his theory of relativity and specifically mass-energy equivalence, E = mc2. Einstein received the 1921 Nobel Prize in Physics \"for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect.\"[1] Einstein\'s many contributions to physics include his special theory of relativity, which reconciled mechanics with electromagnetism, and his general theory of relativity which extended the principle of... |
