I recently learned what entropy is (sort of) and I have a basic grasp of
what the second law of Thermodynamics means.
What it seems to say, to me, is that it's impossible for the amount of
"order" to increase in a closed system.  And if we accept the fact that the

In a discussion of Heisenberg's Uncertainty Principle I read that we
must shine light on a particle to measure its position and velocity.
How does this work exactly? Does the particle cast a shadow on a wall
detector? Or is its position inferred some other way?

Dear Colleagues,
We are pleased to announce our new study
The problem of physical time in today physics
Preface

I'm engaging in discussion with someone and have found myself going around
in circles, so I'd appreciate some help with a few mundane questions:
Can velocity change without time?
Can acceleration take place without time?

"The Paradox of Zeno"
    The Paradox of Zeno is 2000 years old and its apparent ability to prove
that all motion is impossible was not resolved until the mathematical
techniques of Calculus became available, even though that technique is not

Why is there no corresponding distance or mass phenomenon to the time
phenomenon of the "Twins Paradox" ? Where is the asymmetry?
I've seen a condition that space is isotropic but space and time are
homogeneous (isn't time also isotropic?) If this explains the lack of

Could someone give me a reference (on the web) for the paradox of the
bar and the hole (that one in which the bar fall down in the hole in a
reference system fixed with the hole, and don't fall down in the hole in
the reference system fixed with the bar)?

Kia ora,
I’ve recently done a crash course on microarchitecture, and below is a
brief synopsis of what I found.  I also formulated some algorithm base
blocks, that may need tweaking.  I’m still processing how to best
