Question: Are Tegmark's ideas more entertaining than Cornwell 1's physics pornography? Or, are they more of the same? :chin:

I recommend "Ozark" instead. Riveting.

Doesn't sound bad to me. If he chooses a fair judge he'll pick up a few Republican votes as well.

Is this as close to pornography as physics gets? :gasp:

Good luck, my friend. :smile:

Look upon my Icon and tremble, all ye of TPF !!

This thread has become nothing more than a conflation between verb and noun of the word "change"

Yes, that's true. But you don't have to read it all. It's good that one can write at length without a referee stepping in and limiting your flow. But ...

In Wikipedia he is quoted as saying, "Turtles all the way down" Has he gone beyond this view? I haven't read anything by him.

Good point. Fortunately that's not an issue normally in a mathematical discussion. Of course there may be other "rules" generating that finite sequenc...

Barely a glimmer. Wiki: Those were the good old days. :halo:

:lol:

It would seem another physicist has entered the room :clap:

Climber :cool:

That idea seems to predict well, but it models phenomena that are poorly understood.

:up:

There's a wonderful isomorphism between mathematical thought and the physical world. To go beyond that is metaphysical hogwash. IMHO. :roll:

Sure. A derivative can describe a rate of change with regard to a non-time variable: dy/dx

Heh, Heh. :wink:

There are instants of time embedded in infinitesimal intervals.

Of course. :roll:
