Of course, if the sea should get rough or the ship changes course suddenly,__ (87)__ he will sense his state of motion. But even supposing that we have the idealized conditions of a glass  calm sea and a silent ship, nothing that happens below decks — no amount of observation or mechanical experiment performed inside the ship — will reveal its velocity through the sea. The physical__ (88)__ based on these facts was formulated by Newton in 1687. “The motions of bodies included in a given space”, he wrote, “are the same __(89) __themselves, whether that  rest or moves uniformly__ (90)__in a s traight line.”
