  • Fortunately, my russian teacher wrote "normally", while I had to deal with basically this mess in German, where you only could separate the u from the n and the w from the m by the lines below the u and w.

  • Actually, the (vertical) velocity of the deflected center point of the rubber band is faster than the axial contraction of the rubber band itself (at that point) which is limited by the speed of sound of the material.

    Derivation: Pythagoras, chain rule

    Based on that, knowing the speed of sound of rubber, one can obtain a minimal required length of the rubber band.

  • If you flip a coin, the result has two possibilities: It may show either the obverse side (head) or the reverse (tails). These possibilities have equal probability ("50:50"), i.e. in 100 times the coin is flipped, statistically both sides are shown 50 times.
