I Am a Strange Loop
I Am a Strange Loop is a 2007 book by Douglas Hofstadter, examining in depth the concept of a strange loop to explain the sense of "I". The concept of a strange loop was originally developed in his 1979 book Gödel, Escher, Bach. Hofstadter had previously expressed disappointment with how Gödel, Escher, Bach, which won the Pulitzer Prize in 1980 for general nonfiction, was received. In the preface to its 20th-anniversary edition, Hofstadter laments that the book was perceived as a hodgepodge of neat things with no central theme. Hofstadter seeks to remedy this problem in I Am a Strange Loop by focusing and expounding on the central message of Gödel, Escher, Bach. As an exploration of the sense of "I", Hofstadter explores his own life, and those to whom he has been close.[4][5][6][7][8][9] See also[edit] References[edit] Jump up ^ Hofstadter, Douglas R.

Horticulture :: Greenhouse cultivation
1. Designs and classification of greenhouse 2. Orientation Of Greenhouse / Polyhouse 3. Components of green house 4. Plant growing structures/containers in green house production 5. 1. Greenhouses are frames of inflated structure covered with a transparent material in which crops are grown under controlled environment conditions. Classification of greenhouse based on suitability and cost a) Low cost or low tech greenhouse Low cost greenhouse is a simple structure constructed with locally available materials such as bamboo, timber etc. Carnation under low cost greenhouse b) Medium-tech greenhouse Greenhouse users prefers to have manually or semiautomatic control arrangement owing to minimum investment. c) Hi-tech greenhouse To overcome some of the difficulties in medium-tech greenhouse, a hi-tech greenhouse where the entire device, controlling the environment parameters, are supported to function automatically. Cost involved 1. 2. 3. Classification as per type of structure a. Top 2. 3.
Classification System | The Daffodil Society
What do those numbers and letters mean? What are all those number and letter combinations that appear in daffodil catalogues? The Daffodil Society follows the Royal Horticulture Society’s (RHS) daffodil classification system. In 1975, the RHS adopted a colour code system devised by American Dr. Tom Throckmorton. The letter refers to the colours of the daffodil as follows: W – White or WhitishG – GreenY – YellowP – PinkO – OrangeR – Red Daffodils are given a colour code to describe both the perianth (petal) colour and the cup colour. See the photo of Kaylee Ann below as an example: All daffodils are classified into one of thirteen divisions.
Perianth
Diagram showing the parts of a mature flower. In this example the Perianth is separated into a Calyx (sepals) and Corolla (petals) The perianth (sometimes called perigonium or perigon) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs. The term perianth is derived from the Greek peri, meaning around, and anthos, meaning flower, while perigonium is derived from gonos, meaning seed, i.e sexual organs. Flowering plants[edit] When the corolla consists of separate petals the term apotepalous is used, or polypetalous where there are many petals. Both sepals and petals may have stomata and veins, even if vestigial. Corona[edit] Flower of Narcissus showing an outer white corolla with a central yellow corona (paraperigonium) Ligulate floret, typical for flowers of some members of the family Asteraceae:A. ovaryB. pappusC. thecaD. liguleE. style with stamen Liverworts[edit] Bibliography[edit] Simpson, Michael G.

Definitions of Sciences and Studies
Sciences and Studies This list defines 633 sciences, arts and studies of various degrees of respectability and rarity, ranging from the common and esteemed (chemistry) to the obscure and quirky (peristerophily). Over the past century, the range and scope of scientific endeavours has expanded exponentially, so that practically any field of study has a name associated with it. Most of these terms end in 'ology', from the Greek logos, meaning 'word'. I hope you have found this site to be useful.
Seven Volcanoes In Six Different Countries All Start Erupting Within Hours Of Each Other
Seven Volcanoes In Six Different Countries All Start Erupting Within Hours Of Each OtherA new island has appeared in the Pacific. A submarine eruption just off Nishino-Shima Island Japan has erupted for the first time in 40 years. The Japanese Navy noticed the explosions as boiling lava met sea water giving rise to plumes of steam and ash. Almost 7,000 miles away in Mexico, the Colima volcano blew its top after a period of relative calm. In Guatemala the ‘Fire Mountain’ belched out lava and sent up a moderate ash cloud causing an ash fall over nearby towns. In Vanuatu the Yasur volcano is giving some cause for concern. Over to Italy, Mount Etna is putting on quite a display. The Etna eruption (Nov 17th) In Indonesia a four mile high ash cloud is making life hard for residents. Mount Sinabung ash cloud Still in Indonesia but on the island of Java this time, Mount Merapi exploded yesterday. So, we have eruptions big enough to prompt evacuations.

Mind-to-mind thought talking possible by 2030, scientist says
Today we enjoy basic conversations with our smart phone, desktop PC, games console, TV and soon, our car; but voice recognition, many believe, should not be viewed as an endgame technology. Although directing electronics with voice and gestures may be considered state-of-the-art today, we will soon be controlling entertainment and communications equipment not by talking or waving; but just by thinking! Forget Siri, if future-thinking researchers have their way, your brain could soon be chatting away on the phone. A new implant developed by UC-Berkeley neuroscientist, Robert Knight, could create a game-changing relationship between you and your machines. You may soon be able to transmit thoughts via the Internet using a translator chip implanted in the brain that converts thoughts into words. Enter University of Reading's Dr. In 1998, Warwick implanted a transmitter in his arm enabling him to control doors and other devices. What might this revolutionary neuroscience lead too?
