The intent of my question was that there is no such reflections from mirrors or anything like that.

I guess, I was not talking about artificial constraints like light having to bounce off mirrors and travel a roundabout path etc. In that case, of course, the light from a "cause" event could take a circuitous path and reach the observer's eyes MUCH later than the light from the "effect" event...

If there are 2 events E1 and E2 which have a causal relationship, E1 is the cause and E2 is the effect. We know that there is no frame of reference in which E2 occurs before E1 Now, if there are 2 more events E1x = light from E1 reaching observer X E2x = light from E2 reaching obseever X Now...

Thanks a lot for this . I had no idea about this, i will look it up to see if it helps

So, i was trying to calculate, the net force between 2 point charges in their rest frame, and in a frame where they are moving. So, assume, there are 2 point charges each of charge +q. They are r distance apart from each other and moving parallel to each other with a speed v relative to a lab...

Okay, i think you misunderstood what i meant. When i said "Is the real life complicated enough to change the conclusion to its opposite " , i did not mean the intuitive conclusion. I meant the conclusion reached by Richard in his answer where he takes the idealised case. I thought it was...

Is it possible to get some understanding of what kind of cases, would reverse the conclusion and make center blocks the weakest ? I mean is it an unlikely extreme scenario where this would happen ? Or is it rather more common to have center block be the weakest ?

I agree that real life can be more complicated. My question is : Is the real life complicated enough to change the conclusion from what Richard concluded to its opposite, i.e In real life, will center block be weakest , rather than the answer reached by Richard that center block will be...

Like i said before, If the result in case of real life is same as result in case of simplified assumptions, then i feel comfortable with making those assumptions. If the real life case is the complete opposite, then i feel we need to ditch as many assumptions as are required and reasonable so as...

How is this possible ? Shouldnt it be always 50/50 ? Given that the structure is in a stable condition , everything is at rest. So, no matter , additional complications of bending, deformation, torque etc. shouldn't we be able to conclude that the two pistons exert idential forces ? Otherwise...

One more point, one of the answers seems to be getting confused and making it unnecessarily more complicated by considering the coefficient of friction between block and hand . There is no need to have an additional complication of a human hand. I think this confusion came about by my use of the...

Also, i agree with the following very much We should aim for the simplest model . If the conclusions from the simplest model are drastically inconsistent with the reality, then we should include as many real life complications as are reasonable that gives a conclusion consistent with reality,

Okay, when asking about intuition, i do not mean we should reject the maths JUST BECAUSE it disagrees with intuition. I am interested in intuition , because whenever the maths disagrees with intuition , it is very interesting to sometimes consider why our intuition is different. Most of the...

Okay, i might have asked a question that seemed simple to me at first glance but looking at all the different answers, i guess it is much more complicated. I am grateful to everyone who tried to answer. I am sorry that i had not watched this space recently, and so could not answer some questions...

I am not badgering you to agree to anything. You are free to disagree with everything and anything. I am asking you to share what your intuition tells you would happen. Me asking for your intuition in no way implies that i am putting intuition on a higher pedestal. I am also fully agreeing that...
