anuttarasammyak replied to the thread Undergrad Momentum measurement and uncertainty.https://www.feynmanlectures.caltech.edu/III_02.html#Ch2-S2 might be of your help. Momentum is wave number multiplied by Dirac constant... -
anuttarasammyak replied to the thread Undergrad Single-photon double-slit with multiple apparatus?.Probability is essential in QM. A same exact condition produces not unique but varied results which are under law of probability. In... -
anuttarasammyak replied to the thread Undergrad Single-photon double-slit with multiple apparatus?.Experiments including one in post #3 have shown so and nothing new. Photons are independent. A photon interferes with only itself. -
anuttarasammyak replied to the thread Undergrad Single-photon double-slit with multiple apparatus?.My favorite single photon Young double slit experiment by Hamamatsu Photonics in 1982 is here. https://photonterrace.net/en/photon/duality/ -
anuttarasammyak replied to the thread High School What if we could use a Black Hole as starship?.Another orthodox way to make use of BH for travel. You happen to find a BH moving to your destination. You hitchhike and get off at... -
anuttarasammyak replied to the thread Graduate Time evolution of a detected particle.Another approach. $$<\frac{v^2}{c^2}>=<\frac{p^2}{m^2c^2+p^2}>=\frac{<p^2>}{m^2c^2+<p^2>}=\frac{(\triangle p)^2+<p>^2}{m^2c^2+(\triangle... -
anuttarasammyak replied to the thread Graduate Time evolution of a detected particle.The probability that we get momentum in finite region say [-p,p] is infinitesimally smaller than we get momentum in the outside region... -
anuttarasammyak replied to the thread Graduate Time evolution of a detected particle.No. Uncertainty of momentum is infinite so the particle has almost light speed. Furthermore particle anti particle pairs with similar... -
anuttarasammyak replied to the thread Undergrad Is infinity a necessary concept?.1 and 2 are not troubles for me. 3 is not correct saying. $$1+2+3+4+… \neq \zeta (-1) =-1/12$$ -

Messing around in the basement you accidently come up with faster than light drive. You're a billion light years from home! Great... -
anuttarasammyak replied to the thread Undergrad Best way to numerically solve this system of equations?.Thanks. How about s ? Say s=0.5, please find attached my calculation in EXCEL sheet where I try inputting ##K=\frac{1}{\lambda}## so... -
anuttarasammyak replied to the thread Undergrad Best way to numerically solve this system of equations?.Thanks for the comment. I should appreciate it if you share values of setting parameters : ##c_j##'s , s and ##V_f ##. I would like... -
anuttarasammyak replied to the thread Undergrad Best way to numerically solve this system of equations?.We should solve the equation of ##\lambda## $$\sum_{j=1}^n c_j\ln(1-\frac{1}{c_j \lambda}) - \ln s \sum_{j=1}^n c_j - V_f=0$$ N's are... -
anuttarasammyak replied to the thread Undergrad Best way to numerically solve this system of equations?.Following #5, we get equation for ##\lambda## $$c_1 \ln(1-\frac{1}{c_1 \lambda})+c_2 \ln(1-\frac{1}{c_2 \lambda})=V_f+(c_1+c_2)\ln s$$... -
