I was thinking about the expression, “Time Flies by Quickly” slowly… One can look at it at a piecewise level of granularity or in wholesome. Let us try to analyse it. If time flies by quickly, that should mean that every day, hour, minute and second involved should fly by quickly too. Is it true? Usually, when we are less occupied, we feel boredom. What it means is that, we are striving hard for time to pass by and it really doesnt “fly” by quickly. However, when taken to macro level, we look back and if we dont have anything interesting to report, we think that time flew by quickly, when it really should have been the other way around… Another view on that would be, if we are very much involved in doing something, we dont realise how much time was spent. That would mean that, if we are doing something that we like, we lose the notion of time and time does fly by quickly. Interestingly, in this case, we have a lot to report as we look back. So, it seems to me that, our notion of time at a piecewise level of granularity is not the same as looking back after a period of time in its entirety. Where is the discontinuity? Something to think about??
