Being a graduate student means you are free to do and implement your ideas for experiment, sort of an independent research. But there's no such thing as independent research, at least in my opinion. You still need to meet with your graduate adviser to discuss your progress and check if what you are proposing is feasible in the realm of science and the latest technology. Besides, your adviser is the expert, his line of thinking is very different from the student.
I been working with an expensive (expensive over-all and its maintenance, a superconducting magnet that needs to be cool down 24/7) instrument for over a year now, and I thought I know most of the tricks. In turns out I don't. My boss told me about signal to noise ratio, the resolution, the nyquist criteria, zero filling and apodize. I know it sound like a different language but I'm blogging this to remind me that education is a continuous process.
You learn new things everyday.
