3. Programmer fixes 10 of the bugs and explains to the testing department that the other 10 aren’t really bugs.
4. Testing department finds that five of the fixes didn’t work and discovers 15 new bugs.
5. Repeat three times steps 3 and 4.
6. Due to marketing pressure and an extremely premature product announcement based on overly-optimistic programming schedule, the product is released.
7. Users find 137 new bugs.
8. Original programmer, having cashed his royalty check, is nowhere to be found.
9. Newly-assembled programming team fixes almost all of the 137 bugs, but introduce 456 new ones.

Robert Sanderson Mulliken

Born 7 Jun 1896; died 31 Oct 1986 at age 90. American chemist and physicist who received the 1966 Nobel Prize for Chemistry for “fundamental work concerning chemical bonds and the electronic structure of molecules.”In 1922, he first suggested a method of isotope separation by evaporative centrifuging. Thereafter, most of his research career was concerned with the interpretation of molecular spectra and with the application of quantum theory to the electronic states of molecules. With Friedrich Hund, he developed the molecular-orbital theory of chemical bonding, based on the idea that atomic orbitals of isolated atoms become molecular orbitals, extending over two or more atoms in the molecule. He also made major contributions to the theory and interpretation of molecular spectra.
