 Nov 19 awarded Revival Oct 6 awarded Yearling Jun 30 awarded Popular Question Jun 22 comment Woman arrives 6s late for the train. Find her velocity to reach it The relavant quadratic equation is $d_t-d_w = at^2/2-v_m(t-6) = 0$ This quadratic has one solution when $v_m^2 = 4*a*6*v_m/2$ giving $v_m = 4.8m/s$ Jun 21 comment Woman arrives 6s late for the train. Find her velocity to reach it equation 1 is wrong $d = \int at dt = at^2/2$ that is all. No extra terms That is ofcourse assuming train starts are zero velocity. Who is teaching you this subject. You seem to be making elementary mistakes. Jun 21 comment Woman arrives 6s late for the train. Find her velocity to reach it Sketch it on a (x,t) PLOT, try using different velocities v. Notice that drawing a tangent will be the best possible solution, Once you understand how to do that. you can convert it into an algebraic problem. Jun 21 revised Generalization of De Rham cohomology for spinor fields deleted 2 characters in body Jun 19 awarded Talkative Jun 19 revised Generalization of De Rham cohomology for spinor fields Modified question to highlight interest of this site. Jun 19 comment Generalization of De Rham cohomology for spinor fields @Qmechanic Why not? I don't see what the problem is? There are different people on each site, I suspect they will have a different point of view. In any case David barmoshe wanted to answer on PSE because he wanted to give a answer rooted in physics. Which is why I posted it here. I guess I can request a transfer from MSE. Jun 19 asked Generalization of De Rham cohomology for spinor fields Jun 15 comment Invariance of supersymmetric Yang-Mills theory under supersymmetry @Qmechanic If you or others think the tag is appropriate go aheard. I don't like the idea because, the implication seems to be that the question will not be answered fully, but only hints will be provided the general direction. I would much rather prefer a full answer with all the details involved. It would also be useful as resource material for anyone interested in this question. Jun 14 revised Invariance of supersymmetric Yang-Mills theory under supersymmetry Tag Homework and excercises does not apply here in my opinion. It is not preferable to guide the asker, It would rather have a full answer.

Jun 11 comment Wheeler's delayed choice experiment @CuriousOne I don't disagree with what you say about weak measurement and so on. I really wanted to avoid talking about Quantum field theory for now, but since you brought it up again. The point is excitations of the quantum field are quantized, which is what we call particles. You can never have Half a particle(Or half an excitation). The point I am making is that there are no such thing a particle. There is only particle like phenomenon. Jun 11 comment Analogy for the AdS/CFT Correspondence Ofcourse it is the case that we are nowhere near to Test conjunctures like holography. It may take decades it may take centuries it doesnt matter. It is theoretically motivated at the present.
