The Eternal Thing

Special relativity states that the light speed is always fixed. This was (and is) very counter intuitive to understand, but it is what it is.  For example, if you are going at a speed of 0.8c (c = speed of light) along the direction of light,  then the conventional (newtonian) physics says that the relative velocity between you and the light is 0.2c only! That light appears to go slower if you are travelling faster.  But special relativity says NO! Irrespective of our speed, we always measure the speed of light as 'c'. It's just that. Light speed never gonna change (in this universe). Also it's the maximum limit of anything that can move. Especially, if any particle has a mass (or to be more specific, rest-mass), then they can never reach speed of light. Now, see it in the other way around. If anything is going at less than speed of light, it should have a mass (again, rest mass) right? How about when light itself is slowing down?? Yes. Refraction. Does light gain mass ...

  Maybe when we were asked to pay for drinking water - we should have known.  That something was going wrong. It was not all right. When they were demanding money (or) selling it as a feature - the things that are supposed to be basic, we should have given it a thought.  We were too busy. We ignored many things. Maybe that was the cause for the today's effects.  NOTE: Thanks ChatGPT for producing this piece- We drank from rivers without fear, Now we sip from plastic, year by year. The water flows behind a brand— And thirst obeys a bottled stand. The wind was once a mother's balm, Now sold in purifiers, stripped of calm. Air itself wears price tags now, And forests bow to urban vow. The night once wrapped us in soft sleep, Now screens invade, and silence weep. We pop a pill to close our eyes, While time slips past in lullaby. The sun was free to touch our skin, Now we chase it in capsules thin. Vitamin D in boxes sold— A warmth we traded, cheap and cold...

  On the occasion of Teacher's day, I wanted to remember my fav teachers in school/teacher and their quotes that stayed fresh in my mind after many years. NOTE: I may not remember the exact words. These are just from my memory. Anyway, who cares?   From my social sir in school:- When does a revolt rise? When people lose their patience. From my Sanskrit sir in jr. college:- There is no edge for knowledge. From my chemistry sir in jr. college:- No one wants to return from the death. Maybe death is very beautiful. Also from the same sir:- When you comb your hair, your focus should be on completely on your hair and the comb. Also from the same sir:- In a forest, the tallest animal is Giraffe. The wisest animal is fox. The largest animal is Elephant. Lion is none of them. But still he is king of the jungle. From my maths sir in jr. college:- (he said in a form of poem which his teacher told) I am going through a forest,  On the way there was beautiful trees,  with bloomin...
