"interest in the Physics department" - MIT admissions: Part 2

Although you may not yet know what you want to major in, which department or program at MIT appeals to you and why? (100 word or fewer )

My main interest is the Physics department. Whenever somebody asks me " why physics? " my reply usually is " I've always been interested in the Why's and How's of things. Because with understanding how somethings work or why somethings act the way they do we can duplicate the effects to some extent if not in full. And doing so may help us improve some aspects of life. Needless to say, the sensation that comes with discovery is far greater than anything I have ever experienced.And since physics deals with every natural phenomenon known or unknown to man, I have chosen to study it."

Is this good enough? Oh and I have to reduce it by two words.

I think you have to reformulate " my reply ususally is"
Some things are two words
"The sensations that comes with discovery is far greater than than that anything esle can bring" is better.
