Hi, the rocket in space qualifies as an isolated system; most of the systems on Earth which are of interest to us like cars don't qualify to be isolated as they interact with the surrounding environment to serve their assigned purpose. Momentum Conservation principle (MCP) can only be applied to...

Could you please give me an example? And moreover, If two torque equations (considered from two different points on the plane say in case of 2D) are such that the torques are parallel to each other then does that always imply redundancy or not? Thank You

Say, I have a system at rest. I was wondering - how many equations of motion can the system have (without redundancy)? Well, I thought that equating the forces along 2 or 3 different axes would give 3 independent equations. Also equating torques would give some equations, but how many of them...

Why do we sandwich operators in quantum mechanics in such a way that the operator acts on the wavefunction and not on its complex conjugate?

Well I read it in the first chapter

I read in Griffith's quantum mechanics that in a particular system, the second time measurement of the position (say) would yield the same result (the same collapse or the same spike)given that the measurement is done quickly (since it soon spreads out). I don't understand how quick this is...

Soon after selection rules in chapter 6 there is an highlighted box with heading quantum electrodynamics

Modern physics book by Arthur Beiser. He refers to this while discussing vacuum fluctuation

Well, i came across the so-called both the forms of the uncertainty principle of Quantum Mechanics: the position-momentum form and the energy-time form; but i am not satisfied in one way. Here the trio: position, momentum and energy, all of them have their own operators, but time does not have...

The Transition State Theory assumes that the transition state could be considered as a "thermodynamic entity" . But i don'y get the term within the quotes.

I don't understand of what a "thermodynamic entity" is?

What happened to the membrane bound organelles that were present in the eukaryote that gulped the primary endosymbiont (that is, the eukaryote that gulped a prokaryote), after the secondary endosymbiosis.

what are "partial waves" ?

This is a snapshot from the page that follows, from the same book.
