>What about speeding up time tho?
I was talking about the Galileian group (10 dim) without the translations (in 4d). There's no speeding up time, it's quite a plain thing.

We're all faggots, but anybody taking the effort of writing more than 5 sentences in response should stay imho

I do that too, it helps the conversation tbqh and also helps you find your own posts. If I add a random pic to the post, I can easily read up what I missed tomorrow from where I left it.

you didn't answer my question

By the geometric series for |x|<1,

[math] \sum_{m=0}^\infty x^m = \frac{1}{1-x} [/math]

so

[math] \sum_{m=2}^\infty x^m = \frac{1}{1-x} - (1 + x) [/math]

so

[math] \sum_{m=2}^\infty (1/n)^m = \frac{1}{1-1/n} - (1 + 1/n) = \frac{1}{1-1/n} - \frac{1}{1-1/(n+1)} [/math]

[math] \sum_{n=2}^\infty \left(\frac{1}{1-1/n} - \frac{1}{1-1/(n+1)} \right) = 1 + (-a+a) + (-b+b) + (-c+c) + ... [/math]

good thread
