Every  Calculus  student  is  familiar  with  the  classical  Rolle’s  theorem  stating that if a real polynomial  p satisfies  p(−1) = p(1),  then it  has a critical  point  in  (−1, 1). In 1934, L. Tschakaloff strengthened this result by finding a minimal interval, contained in (−1, 1), that holds a critical point of every real polynomial
