    Oil immersion microscope

    Thanks for the reply! I'm a little confused though; what do you mean by maintaining mechanical alignment between the objective and moving sample? The specimen would be a layer of gel spun onto a substrate, so there is no flow, with a coverslip on top. Do you mean that in moving the specimen in...

    Oil immersion microscope

    For oil immersion microscopy, I understand that the oil is required to increase the numerical aperture, and thus the resolution, of the lens. I have tried looking into these microscopes and the only method I have seen of applying the oil is to place a dot of it on the lens and then lower the...

    Statistics - normal distribution

    I think I might have got it now... So for this new variable Y=X1-X2, I have to also calculate a new standard deviation which is sqrt(0.12 + 0.12) = 0.1*sqrt(2) So P(X>0.3) = 1 - P(X<0.3) = 1 - Phi[0.3/(0.1*sqrt(2))] = 1 - Phi[2.1213...]...

    Statistics - normal distribution

    Homework Statement A plant manufactures 500 components a day with the diameter being random variable: N(8.02, 0.1^2)mm What is the probability of two randomly picked components differing by more than 0.3mm? 2. Solution I know that the solution is 0.966 The Attempt at a Solution I thought...
