The Nobel prize 2023 for physics goes to Agostini Krausz and L'Hullier for their contribution to attosecond physics. An attosecond is one billionth of a nanosecond. 'The Nobel laureates developed experiments to produce ultrafast laser pulses, which can be used to understand the world at a really minute scale with applications across chemistry, biology and physics' - (The Hindu) I browsed to find about the concept of time in ancient Bharat. It is interesting to note that a Truti is the minutest applied concept of time found in the Vedas. A Truti is 1/ 1687.5 of a second. I also came across the term Kranti. A Kranti is supposed to be the 34,000th part of a second. This much for micro time. Days▪️, months▪️, years▪️ , clusters of years called 'Yugas'▪️(Satya, Treta, Dwapara and Kali) which come one after another cyclically after great deluges, Yugas grouped into four to mark a unit of time called 'Maha Yuga,'▪️when peace declines to dischord , 71 such Maha Yugas making up a time scale called 'Manvantara'▪, and 14 such Manvantaras making up a 'Kalpa'▪.There are even 30 names of such 'kalpa's mentioned. Our present time is somewhere as we know in the 'Sweta varaha kalpa', 'Vaivasvata manvantara', and 'Kali yuga'. This much for mention of macro time in the ancient texts of Bharat. Brahma's day is a Kalpa and his night another Kalpa when everything dissolves. It is noted that Brahma's lifespan is 100 such years after which even Brahma dissolves and Vishnu goes to sleep on his Sheshnag. When He wakes up He would bring forth another Brahma. It is amazing that the ancient people of Bharat had names for the measurement of minute fractions of seconds, and incomprehensible stretches of time. Vishnu is space and verily all creation. History of a scientifically super-advanced civilisation lies buried in the Vedas, Itihasas and Puranas of Bharat. Ignorance of the later generations has led to much embroidery which hides the truth. It is a pity that Scientists don't understand Sanskrit to get to the hidden treasure of knowledge.
