Gbenga,
Among the essays of this contest, your very original essay is certainly the one that takes the most time to explicitly state physical laws, in your attempt to link them to the question of humanity steering the future. You invoke conservation of energy and Newton's third law to justify the importance of keeping our world in equilibrium (p.3), you take the time to fully work out a basic example of conservation of momentum (p. 4-5), you explain in detail the mechanism of the greenhouse effect (p. 6), you optimistically state that, as falling objects obey "g", suicide bombers and global tyrants must obey the laws of physics or be brought to judgment (p. 7), you compare the spreading of a gloomy future to a sound wave... and even feel the need to give the equation that relates frequency, speed and velocity (p. 7-8)!
In the end, you state that humanity should "steer a better world by allowing the force applied to be proportional to the rate of change of momentum that should take place in the direction of the force". Since we don't really have a choice (Newton's second law will remain true no matter what we do), I suppose this means that everything will turn out all right. Let us hope you're right!
