You may us the Parallel Kernel Status tool or may be able to use CloseKernels. Parallel Kernel Status Launch the tool from the Evaluation | Parallel Kernel Status menu. If the kernels are already running then you will see them listed. There is a Launch All button if none are running. You can either close individual kernels or close them all. ...

In Windows you can create a .cmd file with the following lines in it: tskill mathematica tskill wolframkernel tskill mathkernel Executing it will make sure that all Mathematica processes are closed.

This is a bug that has been fixed in Mathematica 10.3.0 and later. The cause of the crash is one of the computations that the predictive interface tries in the background, so a workaround for earlier versions would be to turn off the Suggestions Bar by unchecking the box in Preferences.

This was introduced in 10.0 and fixed in 10.3. curve1 = {Cos[φ] (4. - 1. Cos[4 φ] + 1. Cos[8 φ] - 1. Cos[12 φ]), (4. - 1. Cos[4 φ] + 1. Cos[8 φ] - 1. Cos[12 φ]) Sin[φ]}; curve2 = 2. - 1. Cos[4 φ]; tangent1 = D[curve1, φ]; surface = {{Cos[3 z], Sin[3 z], 0}, {-Sin[3 z], Cos[3 z], 0}, {0, 0, 1}}.Append[(1 - Sqrt[1 - Abs[z]]) (...

This isn't a very satisfactory answer, but it turns out that this exact same code works on version 10.4.0 for Linux x86 (64-bit) (February 26, 2016) on the same OS and laptop, and as @JHM points out it works on a Windows machine, therefore I suspect this might be a version+OS specific bug. In any case, my problem is solved.
