Change is the only constant in life! - Heraclitus, On Nature (-500) the only law nature follows is, Change. make the best of this beautiful and fleeting available cosmic window. प्रकृति में परिवर्तन ही एकमात्र स्थाई है! तो क्यों न हम इस खूबसूरत और क्षणिक अलौकिक पल को जियें आनंद और उत्साह से   Equating the 4.5 billion years of the earth to 24 hours of a clock in which a second signifes 52,000 years; a minute 31 lakh years; and an hour 1.87 crore years, the scientist computed that humans arrived around 30 seconds to midnight. "The intervention that has happened since industrial revolution signify just 4/1000 of a second before the clock struck 12," the scientist said, highlighting the insignificance of man in the scheme of things.
