Lab Report was an improvisational, dark ambient, band created by Matthew Schultz, Eric Pounder and Chris Blazen in 1989. The experimental project gained notoriety as one of the earliest dark ambient musical projects stemming from the Industrial music genre.
I have been able to cut it down quite a bit and when I worked out the uncertainties and made the conclusion my teacher was unsure about my uncertainties.
Hello everyone,
I am now doing experiment related to quantum erasure. After plotting the correlation measurement with and without blocking one of the polarization from the SPDC source (say, V polarization), I do not know how to work further on the gating time from the rate of the random...
I have done the experiment, and have a lot of data. For each data point (we have five), we did ten repetitions, for which we need to do video analysis. The analysis works frame by frame and gives a velocity between each frame. So, to get the value of one repetition, we already need to calculate...

For my lab report I am asked to calculate the error of a couple of measurements which I did with a lux meter. I know that the lux meter has tolerance(or accuracy?) 5%. The instrument is digital and it's last digit is 0.1. The maximum reading is 47.5 lux.
