The discussion centers on the relevance of the concept of "now" in the context of special relativity and everyday interactions. Participants question whether understanding special relativity impacts daily communication, such as knowing what a friend is doing in a different location. The consensus is that for practical purposes, asking someone directly is more meaningful than contemplating the implications of relativity. Ultimately, the notion of "now" is deemed less significant in day-to-day life. The thread concludes that special relativity is not necessary for everyday interactions.

TL;DR
Is it meaningful to ask what say, my friend is doing in London when I am in New York?
So, not looking for anything over complicated. Just been picking up some special relativity.

How meaningful is the notion of now here on Earth? Is special relativity worth even considering for day to day interactions with others?

Thread 'The Einstein Clock aka Light Clock'

Hello, everyone, hope someone will resolve my doubts. I have posted here some two years ago asking for an explanation of the Lorentz transforms derivation found in the Einstein 1905 paper. The answer I got seemed quite satisfactory. Two years after I revisit this derivation and this is what I see. In the Einstein original paper, the Lorentz transforms derivation included as a premise that light is always propagated along the direction perpendicular to the line of motion when viewed from the...
