### Learning From Teachers

Eight-year-old Sally brought her report card home from school. Her marks were good...mostly A's and a couple of B's.

However, her teacher had written across the bottom: "Sally is a smart little girl, but she has one fault. She talks too much in school. I have an idea I am going to try, which I think may break her of the habit."

Sally's dad signed her report card, putting a note on the back: "Please let me know if your idea works on Sally because I would like to try it out on her mother."

## G. Johnstone StoneyDied 5 Jul 1911 at age 85 (born 15 Feb 1826). George Johnstone Stoney was an Irish physicist who coined the term electron for the fundamental unit of electricity. At the Belfast meeting of the British Association in Aug 1874, in a paper: On the Physical Units of Nature, Stoney called attention to a minimum quantity of electricity. He wrote, “I shall express ‘Faraday's Law’ in the following terms ... For each chemical bond which is ruptured within an electrolyte a certain quantity of electricity traverses the electrolyte which is the same in all cases.” Stoney subsequently offered the name electron for this minimum electric charge. When J.J. Thomson identified cathode rays as streams of negative particles (1897), each carrying probably Stoney's minimum quantity of charge, the name was applied to the particle rather than the quantity of charge. |

## MAGIC SQUARE: Calculate A-B+C

The aim is to place the some numbers from the list (7, 9, 14, 15, 16, 22, 54, 56, 62, 86) 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.#brainteasers #math #magicsquare
