Is it possible to make prism deviation angle minimum (as a function of incidence angle) more abrupt?

Dear Sirs, The setup for the dispersion measurement is as follows. Hg lamp, collimator, goniometer with triangular prism. We measure the light dispersion using the prism. To do so we determine...

What is a meaning (practical and theoretical) of 1st Newton law? Can we partially check the law?

Dear Sirs, The 1st law in Newton`s principia are now understood as two statements: the determination of inertial frame reference (if F=0 then a=0 and if F is not equal 0 then there is some body...

How do we find/construct closed system needed to use Newtons laws?

Dear Sirs, 1, 2, 3 laws of Newtons need closed system (net force is zero). How do we practically realize, create such closed system? One example. Let us look at a body motion. One can say If...

Are there self-replication simplest mechanical models (to understand living creatures)?

Dear Sirs, I did not find this material on the internet. There are only mechanical models of some aspects of self-replication. Full mechanical model is absent. Of course it is enourmous problem...
