It seems there is still an argument on whether acceleration is needed or not. Two opposing viewpoints. Pro against Who's right for the general layman ? I was thinking about this on the dog walk and it did indeed make it go quicker. Though neither of us were any younger sadly.

Good morning, I was thinking about this on a dog walk yesterday ( it makes the passage of time fly by) . How would I describe to someone for instance what the number 4 is without using other numbers or by applying something like addition or subtraction etc. Obviously you cannot say it is the number between 3 and 5 as that uses other numbers to define it. Then I thought about drawing 4 lines. But then of course I am mentally counting them as a draw them, and know when to stop in the addition. Next I thought of dice with their 1 to 6 in different patterns. 4 could be always that pattern of the 4 dots, which would negate any counting in the "description". The problem with that technique is of course you can't extrapolate it for a general principle. Imagine pattern matching 12 556 987 2444 98763 as a number, or even worse, 0.0025. At that point I thought I would give up, I am not a mathematician, and thought I would ask someone more experienced. So I joined this forum. Hello by the way. Is there a way of describing a number simply without using maths and its constituents? I am guessing not but I might have missed something obvious. Many thanks for any input, I am on a dog walk soon and will think about the twin paradox to make the time go faster.

There is for optics and electromagnetism, which was the problem that was causing problems around the turn of the 20thC. Classic mechanics was failing with various experiments and it was the new idea of time not being independant of location that linked it together so both sets of results could be explained. The Lorantz transformations are used between different co-ordinate systems that have relative velocity to work out the relative time component. Especially with trains and embankments ! ( joke ). I hope I have got that right, obviously corrections will be welcome.
