Yes, it is quicker... I don't know if it is because you do not have such an experience to compare with but is quicker and easier. If your hands are full of things then it does save a few seconds. >The value in understanding mathematics is not the ability to be able to recite the quadratic formula or to be able to perform long division in your head, it's knowing when to use the formulas and understanding their applications in your daily life and work. You can do both, really. You should be able to recite the mathematics you use in your daily work without having to look it up. I've never met a good scientist who wasn't able to. EDIT: okay, may be one exception is for example something like tedious calculations from QFT or something, but you should be able to gesture at general parts of it, you should be able recite certain simple equations or particular approximations. If you have to refamiliarize yourself with your work every time you look at it, I do not know how you can advance in your research.
