The German term null stands for both zero and looser (in the figurative sense). So please read the following with both meanings in mind (puns are just not translatable).

Hugo, a colleague of mine, has the pastime of reading math textbooks. Recently he was studying one on Fourier transform, in which there was a chapter on zero-padding - the method of of extending a signal (or spectrum) with zeros.

The author's first recommendation is: A lot of zeros are good!. He also noted: This rule is also obeyed in business and politics.
