best explanation with great clarity. thank you !

Excellent. The logic and presentation are perfectly clear and complete. As noted in the comments below there was an error in the math in the tables, but the concepts and the formulas are all good. I tried to read the paper from Kwiat, Et al., and I never fully grasped it, but this explanation which uses the same principles makes sense.

Nice video but something doesn't seem right towards the end of the video while computing the table of probabilities .The probability of detecting bomb after two iterations should be 0.25 since probability is (cos(pi/2(2)))^2*2 = cos(pi/4)^4 = (1/sqrt(2))^4 = 1/4 =0.25.
Please correct me if I am wrong
