@mark noble,
No it's not.
While an argument can be made that learning a second language might be helpful to a scientist, which one is the most advantageous?
I can practically guarantee that the Leviathan didn't try to steer this kid to the second most popular scientific language. French, Chinese, German?
This kid can go on to great achievements in science because English is the Lingua Franca of science.
Perhaps he won't be able to access obscure texts not translated into English, but that is a risk not worth considering.
The Leviathan believes in multi-culturalism and so it promotes learning other languages.
There are benefits, to be sure, of learning one or more other languages but it has nothing to do with pursuing a career in science.
