Is spaceman still alive and kicking?

If you're out there floating around somewhere, maybe you'd like to discuss your question from the point of view of Cantor's continuum hypothesis.

or even from the point of view of the wheeler DeWitt equation?

They're all trying to model the same thing without knowing it anyway.

There's not much else going on while we wait for Winston.
And China is moving way too slowly for anyone to notice.

yawn... still waiting for Winston.
Could we actually have a democratic management structure for once.. lets hope.

And spacy old boy.. modern day thinker a bit too much for you? (kidding)
What about Heraclitus and Parmenides.. who do you side with on the subject of measuring and motion and flies and trains?

Another take on the never ending train vs fly question.
(For those of you who have been following this over the years..)

This one was just sitting in my head when I got up this morning.

So, to recap on Spacee's initial problem:
When a train hits a fly, there must be a moment when the fly is stopped in it's tracks , (just before going backwards).
And if the train is touching the fly, at that moment, the train must also be stopped.
So a train has been stopped by a fly.
Well, that was his idea anyway.

So, there are many ways to look at this situation, some better that others.
The one that presented itself this morning might be the one Spacee had in mind, assuming he had solved it, that is.

What is actually going on is that the fly never stops, nor does the train.
Things being in a state of perfect rest would be impossible as we know it.
Time itself would have to stop.
(How our monkey brain enables us to imagine a stopped world is the real wonder.)

So what's really going on with the train and the fly?
The best answer I can give right now is, something completely different to what our human minds can grasp.
A few top mathematicians and physicists have a niggling sense of this, but would struggle to convey it to Joe on the street.

Fortunately, the impression that a fly is pushed backwards by a train works perfectly well for us, in everyday life.
The fact that math and reason disagree should serve as a strong reminder about the truly interesting nature of things

- and to not to get too cocky.
