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."

Electric stove

In 1896, the first U.S. patent for an electric stove was patented by William.S. Hadaway, Jr., in New York City. (No. 563,032). It provided a uniform surface distribution of heat from a one-ring spiral coiled conductor. An earlier apparatus, described as an "electrical heating apparatus," which the inventor termed an "electroheater," was patented by George B. Simpson of Washington, D.C. on 20 Sep 1859 (No. 25,532). Simpson's device utilized the heating effect resulting from passing electric current through coils of wire made from platina or other metals.*
