Because the act of measuring changes the system from its true state. For large systems the percentage deviation of the system from its true state is small. So our measured value closely resembles the true value. But for small systems the percentage deviation of the system from its true state due to the act of measuring can be large which puts a restriction to the accuracy of the measurement we can achieve. We should make sure that our method of measurement has the least amount of interaction with the system.

Suddenly I was selected to the PhD program in Chemistry in Wayne State University, USA. It all happened so quickly and in a few months I found myself in a foreign land. Although I was taught how to cook by my parents I had never practiced it seriously. My first two months in US was a great fight for adjusting to the lifestyle and quickly learning some real time cooking tips from my parents through Skype. They were watching and advising while I added the necessary ingredients.

Well..... then actually I got to know that more or less all the recipes follow the same type of path and concepts so that the end-product was edible. After some time I even started calling my own shots. When you are alone, hungry and under pressure in a foreign country your inner self quickly prepares you to stand on your own. Believe me that really happens. Now I can cook for myself. A great feat which will pay me big time in future.
