Solar power without solar cells: A hidden magnetic effect of light could make it possible

Solar power without solar cells: A hidden magnetic effect of light could make it possible
A dramatic and surprising magnetic effect of light discovered by University of Michigan researchers could lead to solar power without traditional semiconductor-based solar cells. The researchers found a way to make an "optical battery," said Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics. In the process, they overturned a century-old tenet of physics. "You could stare at the equations of motion all day and you will not see this possibility. Light has electric and magnetic components. "This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge separation," Rand said. What makes this possible is a previously undetected brand of "optical rectification," says William Fisher, a doctoral student in applied physics. Rand and Fisher found that under the right circumstances and in other types of materials, the light's magnetic field can also create optical rectification.

24 Terrifying, Thoughtful and Absurd Nursery Rhymes for Children In more repressed times, people were not always allowed to express themselves freely, for fear of persecution. Gossiping, criticizing the government or even talking about current events were often punishable by death. In order to communicate at will, clever rhymes were constructed and passed around to parody public figures and events. The first nursery rhymes can be traced back to the fourteenth century. While the Bubonic Plaque ravaged England, peasants used a rhyme to spread the word about equality. The "Adam and Eve" rhyme made peasants realize that they were important to the economy and contributed to the Peasants Revolt of 1381. Other nursery rhymes don't seem to carry a particular message at all, but convey a macabre sense of humor. Humpty Dumpty Humpty Dumpty sat on a wall,Humpty Dumpty had a great fall,All the King's Horses and all the King's menCouldn't put Humpty together again. In children's books, Humpty Dumpty is portrayed as a large egg, usually dressed like a little boy.

Alice's Adventures in Wonderland Background[edit] Page from the original manuscript copy of Alice's Adventures Under Ground, 1864 Alice was published in 1865, three years after the Reverend Charles Lutwidge Dodgson and the Reverend Robinson Duckworth rowed in a boat, on 4 July 1862[4] (this popular date of the "golden afternoon"[5] might be a confusion or even another Alice-tale, for that particular day was cool, cloudy and rainy[6]), up the Isis with the three young daughters of Henry Liddell (the Vice-Chancellor of Oxford University and Dean of Christ Church): Lorina Charlotte Liddell (aged 13, born 1849) ("Prima" in the book's prefatory verse); Alice Pleasance Liddell (aged 10, born 1852) ("Secunda" in the prefatory verse); Edith Mary Liddell (aged 8, born 1853) ("Tertia" in the prefatory verse).[7] The journey began at Folly Bridge near Oxford and ended five miles away in the village of Godstow. Synopsis[edit] Chapter Twelve – Alice's Evidence: Alice is then called up as a witness. Characters[edit] Symbolism[edit]

Smokey Cheshire Cat I'll sing you one, O / Green Grow the Rushes, O I learned this song from my father, who grew up in Southern England, but I don't know who he learned it from. It is the best of the counting songs, of which he knew several, and which we as a family used to sing to while away the time on long car journeys. I know nothing of the origins of the song, although I would guess that it is very old - seventeenth or perhaps even sixteenth century. We do not even understand all the references. Some are clear enough, and we have guessed at others, but the rest have mystified my sister and me all our lives. Here is our provisional gloss: One is one, and all alone,[PARA]And ever more shall be so. With thanks to Veronica Biggs for her helpful suggestions, and a special thanks to Carl Olson for his definitive e-mail. I saw your gloss on this song and I must disagree with quite a bit of it. | Song Index | Home Page |
