Yes. When I was in school, I many spent long nights in the lab doing frustrating experiments that don't work well. I majored in engineering physics, and the worst labs were on analog electronics design and feedback-control systems. I remember designing analog circuits based on the textbook equations, and then I simulated them on the computer, and the simulated characteristics didn't match my calculations. Then I built the actual circuit and tested it, and the results don't match either my calculations nor my computer simulation. So after many days and nights of work, not being able to get the results to match, I end up adding a lot of "parasitic capacitances" and stray resistances and so on in the math to try to adjust the numbers to be similar. Then the inverted-pendulum balancing feedback control system lab was a lot of trouble, too. The thing never worked very well and we worked so hard on it... Oh, and those frustrating chemistry experiments that don't work! Lab experiments often do not match textbook theory.
