What is reality? Really a nice question! Reality has always been a ball of intellectual game for many people of all the time. People like to talk and debate about it. While doing so, they entertain themselves. So, for many people this question is like a clown to entertain them. Those who are expecting theological answer of this question will be disappointed. I am sorry I couldn't develop myself to believe blindly on some unseen, unknown supernatural power, and buy the concept of being it to be the only real entity. I am a human being, who has a brain to think, analyze and judge. I will accept only those things which are logical, rational, scientific, and result giving. Rest of the things, I will love to put aside and will accept whenever they come to this category, that is, logical, rational, scientific, and result giving. If I say reality is truth, that won't be wrong. However, reality that we perceive may not be the absolute truth. The truth may surprisingly vary for different observers and different frames of reference of the observer. Let me illustrate this point by an example. Suppose; Chettrini is a woman, a beautiful woman whose beauty is praised by the words of the poets. Photographers never get tired to enclose her beauty inside their camera and she is an abstract imagination for painters. Everybody appreciate her beauty. Physical beauty is a truth perceived by our eyes. Anybody who has eye can't falsify the truth of physical beauty. This is one truth. Let's cut a small piece of the skin form her beautiful cheeks, and put them under optical microscope. All you will see is the biological cells and the biochemical reaction inside them. This is another truth. The truth of beauty get disappeared inside the microscope. Now take out that piece of skin from optical microscope and put it under the STM (Scanning Tunneling Microscope = an electron microscope which works under the principle of quantum tunneling), you will see atoms only. Where have those biological cells gone? Now beauty and cells both get disappeared inside STM. This is another truth. contd.............
