TN TET 2012 Paper 2 Math and Science Paper

Most of us use the products of science – railways, aeroplanes, electricity, phones and thousands of others – without thinking how they came into existence. We take them for granted, as if we are entitled to them as a matter of right. And we are very proud of the fact that we live in an advanced age and are ourselves so very advanced. There is no doubt that our age is a very different one from previous ages and I think it is perfectly correct to say that it is far more advanced. But that is a different thing from saying that we as individuals or groups are more advanced. It would be the height of absurdity to say that because an engine driver can run an engine and Plato or Socrates could not, the engine driver is more advanced than, or is superior t, Plato or Socrates. But it would be perfectly correct to say that the engine itself is a more advanced method of locomotion than Plato’s chariot was.
