Fritz Wolfgang LondonDied 30 Mar 1954 at age 54 (born 7 Mar 1900).German-American physicist who, with Walter Heitler, devised the first quantum mechanical treatment of the hydrogen molecule, while working with Erwin Schrödinger at the University of Zurich. In a seminal paper (1927), they developed a wave equation for the hydrogen molecule with which it was possible to calculate approximate values of the molecule's ionization potential, heat of dissociation, and other constants. These predicted values were reasonably consistent with empirical values obtained by spectroscopic and chemical means. This theory of the chemical binding of homopolar molecules is considered one of the most important advances in modern chemistry. The approach is later called the valence-bond theory. |

MAGIC SQUARE: Calculate A+B-C
The aim is to place the some numbers from the list (7, 9, 12, 13, 14, 18, 22, 24, 28, 42) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A+B-C. The first user who solved this task is Nasrin 24 T.
