The Dentist
The dentist pulls out a Novocain needle to give the man a shot, so he can extract the man's tooth. 'No way! No needles. I hate needles' the patient said.
The dentist starts to hook up the nitrous oxide and the man objects I can't do the gas thing. The thought of having the gas mask on is suffocating to me! The dentist then asks the patient if he has any objection to taking a pill. 'No objection,' the patient says. 'I'm fine with pills.'
The dentist then returns and says, Here's a Viagra tablet.'

Gilbert Newton LewisBorn 23 Oct 1875; died 23 Mar 1946 at age 70. American chemist who collaborated with Irving Langmuir in developing an atomic theory. He developed a theory of valency, which introduced the covalent bond (c. 1916), whereby a chemical combination is made between two atoms by the sharing of a pair of electrons, one contributed from each atom. This was part of his more general octet theory, published in Valence and the Structure of Atoms and Molecules (1923). Lewis visualized the electrons in an atom as being arranged in concentric cubes. The sharing of these electrons he illustrated in the Lewis dot diagrams familiar to chemistry students. He generalized the concept of acids and bases now known as Lewis acids and Lewis bases.« |
MAGIC SQUARE: Calculate A*B*C
The aim is to place the some numbers from the list (4, 8, 9, 10, 11, 18, 19, 33, 35, 43) 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.
