This is advanced stuff so I might be wrong, but this video looks good: We could start another topic about that, but such a topic would be much more difficult than the complex numbers topic!

whitesilk Posted September 29, 2018 precisely wandelaar, Now, suppose we western mathematicians might find a frequency with O(N) time, would that refute the uncertainty principle? Share this post Link to post Share on other sites

Time exists because there is movement in space (the universe). Doesn't really matter too much how we measure time. It exists just as does my chair. 4 minutes ago, wandelaar said: We could start another topic about that, but such a topic would be much more difficult than the complex numbers topic! I will make sure to over-look it if it does materialize. Share this post Link to post Share on other sites

SPOILER: end quote, 'as the afgans say, you may have the clocks, yet we have the time.' Yeah, Afghanistan has been invaded by just about every power that has ever existed but it still remains Afghanistan. And the strange thing is that Afghanistan has very little resources. No idea why anyone would want it. Share this post Link to post Share on other sites

No doubt Alexander was a great (maybe the greatest) military leaded. But we can't underestimate the strength of the Afghans. Share this post Link to post Share on other sites

Are you referring to the complexity of calculations? And what frequency are you talking about. How does this all relate to the Heisenberg uncertainty principle? In mathematics of the non-VIYY type we need to be precise about what we are talking about, otherwise the discussion will lead nowhere. Share this post Link to post Share on other sites

Your velocity will grow until the air resistance equals your weight. Higher up in the atmosphere the air will be thinner but you will also weight less. I could start another topic to calculate the effects. 1 Share this post Link to post Share on other sites
