Moreover, according to the Newton's Third Law, the snare drum and my hand are action and reaction pair. Hence, a force which is equal in magnitude but opposite in direction would act on me.

(the reaction takes place with water molecules, and the oxygen comes from the water; the rest of the water molecule becomes a pair of hydrogen atoms, which is also useful).

这个反应是需要水分子的，且氧原子是来自水分子；其余的水分子变成仍有用的一对氧原子。

While this recent run by the euro may be a bit overdone and price has stalled slightly ahead of the 1.2500 level, traders need to be very wary of this pair as the reaction to stress tests, positive or negative, could send it rocketing in either direction.

While I think this could still be a solid area that could stymie further upside potential, the reaction off this zone has not been overly convincing and the pair seems to be finding support near 1.3060 which could act as a launch pad to move higher.

Cleverly, Mr Schama seems to pair each of these active forces with its equal and opposite reaction.
