What is Morin: Definition and 25 Discussions

Morin is a surname of Dutch origin, and the name comes from the ancient Celtic tribe of Morini who once inhabited Gallia Belgica or modern day Belgium. The Gaulish ethnonym Morini (sing. Morinos) literally means 'those of the sea', that is to say the 'sea people' or the 'sailors'. It stems from Proto-Celtic *mori 'sea'. It may refer to:

Morin, flavonol and yellow chemical compound.

    Morin classical mechanics differential equation problem

    I was reading the oscillations chapter which was talking about how to solve linear differential equations. He was talking about how to solve the second order differential below, where a is a constant: In the textbook, he solved it using the method of substitution i.e guessing the solution...

    How much SR is needed for Purcell and Morin?

    TL;DR Summary: How much special relativity Is needed for Edward M. Purcell & David J. Morin It clearly is needed to fully understand this book and I have what seems like a good book that introduces relativity (A.P. French) But I am not wanting to start it yet and it’s around 300 pages long...

    Advancing to Higher Level Electromagnetism: Is Purcell & Morin the Solution?

    Hi I am coming up to the end of first year electromagnetism using the book University Physics. I will be honest there’s a lot of information crammed into a few hundred pages and it was my first ever exposure to EM. I never did it in school. I feel like its give me a good overview but i don't...

    Morin's mechanics problem 2.3 (motionless chain)

    In his solution, Morin solves the problem as the hint suggests: cutting the chain into small pieces, taking the component of the external forces along the curve (which is just the component of gravity here) and summing up an in integral, obtaining 0. He then claims that because the "total...

    Falling and sliding stick (David Morin)

    In the solution for question ##(a)##, it is written that the equation of translational motion for the center of mass is ##N-mg=ma_y## Why ##N## is also included inside of the equation? In my opinion, the rail does not exerting force (N) to slow down the mass' acceleration. Instead, the purpose...

    Why is the tension in a falling chain not equal to ρgy?

    Firstly, There is something I want to clarify. When the system starts moving, parts of the chain that still lies on the table, which have mass ## \frac {(L- y_0)M} {L}##, will be pulled by the force that the hanging chain's weight exert,right? If yes, then : As far as I know, the formula ##F=...

    David Morin classical mechanics Problem 2.6: Disk held up by a massless string

    The first part is easy, we have 2T= Mg T= 0.5 Mg Now for the second part where I'm having trouble understanding Morin's solution: I take the normal force on a small circle arc to be N, we know that the y component of the normal force must be balance with Mg for the whole disk, therefore Ny =...

    Classical Classical Mechanics: Kleppner-Kolenkow vs David Morin?

    Hello, I am confused between the two books. I am looking for a text that would provide sufficient theoretical insight into the topics and provide a good set of problems that would help me understand the topic well enough. What would be your suggestion? PS- Taking a cursory look at both the...

    Morin's explanation about the work done by friction

    Hello all. In his books on classical mechanics, David Morin claims that when computing the work W = F Δx done by a contact force that don’t involve any slipping, we can equivalently say that Δx is the displacement of the thing that is applying the force. Later, when analysing a wheel rolling...

    Prob/Stats Is Probability by David Morin a good book?

    I had taken probability before but not in depth and I want to learn it again. Is David Morin's book good for a intermediate learner ? I don't want to waste time on easy stuff. The reviews are good but popular science books tend to omit proofs instead they just state the theorems and have easy...

    Ok, so here's another example Morin did in his book: Ok, so the thing that confuses me is when he used the velocity addition equation: Note:4c/5 and 3c/5 are their speeds relative to the ground. Where v2 is the velocity of the S' frame, and v1 is the velocity of the object moving in the...

    Infinite Atwood Machine (Morin Problem 3.3)

    I could've peeked at the solution manual and end with it at that. However, I'm trying to change this nasty habit and solve this problem myself. I might be too ambitious. Here goes. Homework Statement Consider the infinite Atwood's machine shown. A string passes over each pulley, with one end...

    I Morin's Rocket Example: Chapter 12, Page 606

    Hello all. In Morin's classical mechanics book, chapter 12 (relativistic dynamics), in the axample about the relativistic rocket, we have a rocket that propels itself converting mass into photons and firing them back. Here Morin takes dm as a negative quantity, so the instantaneous mass of the...

    Kleppner & Kolenkow's or David Morin for mechanics (IPhO)

    I've been down to these two books on classical mechanics, and I can decide as to which to choose. I've heard that the David Morin book has rather nice problems, but isn't quite that excellent with the explanations. As for the book by Daniel Kleppner and Robert Kolenkow, it seems to be good with...

    Kleppner then Morin or quick intro then Morin?

    Looking for a Better Mechanics Textbook? Any Suggestions?

    I'm currently in a mechanics course (second year) that uses the David Morin book (Introduction to Classical Mechanics) which I find to be very unhelpful. It's mostly just problems with very little explanation of the concepts. I'm looking for a textbook to replace Morin's which covers the same...

    Doubt on this worked example from book by David Morin

    Attached is a worked problem in the Classical Mech book by Morin. I don't understand how eqn (2.57) is the net moment about the pivot. Isn't it only the moment of the weight of the portion of the stick to the right of the pivot ? What about the moment due to the weight of length 'l' on left...
