So this article is basically about a practical way of finding the truth rather than wandering into the abstract world.Right?

conceptualizing the truth,in hegel's term. A lot of philosophers(like descartes' three kinds of ideas) in his time (and a lot of mindfulness practitioners these days)believed a higher form of truth(or knowledge) exists which cannot be articulated but is to be intuited and felt.Hegel didnt consider this to be scientific.you can never know if your intuition is true or its just you making the stuff up.

Here are some bonny dialogues fromWonder,a wonderful novelby R.J. Palacio. I admire the last one (fav)

Funny how sometimes you worry a lot about something and it turns to be nothing.(page 215)

The speed of light does not depend upon the temperature of air but the speed of sound depends on it. Why?

As we know that wave of sound is a mechanical wave and its speed is given by

v = (γRT/M)

whereas the wave of light is an electromagnetic wave and its speed is given by

c = (1/εoμo) 

So speed of sound depends on temperature of air but speed of light doesn't.
