Query: Wonderful

If you are interested in science, scientists and its history; If all you remember from your science classes are the names of scientists like Boyle, Van der waals and Joule; if you are ready to be taken on a fantastic ride into the realms of the cold and the story of its conquest.... This is the book for you.I really enjoyed it very much. Not only did I get a better perspective of physics and chemistry but I was surprised at the amount of work that had gone into the construction of the common refrigerator or the air conditioner, to which we never pay any attention. And the personal touch the author added really helped me feel like I was with the scientists when each discovery was being made. Now, I feel like I know Dewar and Joule well enough to call them by their first names!
