    PROTECTOGRAPH
    August 9, 1904 - New York, U.S.A.

    The Protectograph check-writing machine was patented under the title Printing-Stamp by Libanus McLouth Todd of Rochester, New York (U.S. Patent No. 766,853). It was designed to protect against check forgers by marking and embossing the amount on a check, thereby preventing the amount thus shown to be later dishonestly changed to a higher value. The apparatus had co-axial printing wheels with lines of raised type forming a series of numbers and suitable words. A check would be placed between the wheels and a platen. An inked felt-covered roller applied ink to the type as the wheels were turned to select the chosen imprint. The platen surface had a yielding material, such as rubber. When actuated by a hand-lever, it was raised from beneath the check and embossed the paper against the type.

    COLDEST TEMPERATURE ON EARTH SURFACE
    August 9, 2010 - Antartica

    the record low surface temperature in Antartica was -135.8ºF (-93.2ºC), colder than the freezing point of dry ice. It was determined from analysis of remote-sensing satellite data later announced on 9 Dec 2013 at the annual meeting of the American Geophysical Union. The location was in pockets scattered near a high ice ridge between Dome Argus and Dome Fuji, two summits on the East Antarctic Plateau. August is winter in the Southern Hemisphere, and the temperature resulted from the geographical nature and weather conditions in the pockets. The World Meteorological Organization official records are for air temperatures made a couple of meters above the surface. That recorded lowest temperature, made in Jul 1983 at the Vostok Research Station, Antarctica, remains at -128.6ºF (89.2ºC).

  • Until a man duplicates a blade of grass
    by Earth Day, Thomas Alva Edison Inventor

    "...Until a man duplicates a blade of grass, Nature can laugh at his so-called scientific knowledge. Remedies from chemicals will never stand in favorable comparison with the products of Nature, the living cell of a plant, the final result of the rays of the sun, the mother of all life...."
  • A Change is Gonna Come
    by Meredith Grey

    "...Change; we don't like it, we fear it, but we can't stop it from coming. We either adapt to change, or we get left behind. It hurts to grow, anybody who tells you it doesn't is lying. But here's the truth: Sometimes the more things change, the more they stay the same. And sometimes, oh, sometimes change is good. Sometimes change is everything...."

Search engine is the term with which we are accustomed with very much. But the web directory is not that same. The web directories are older than search engines according to the time of their invention. There are some similarities and some differences between search engines and web directories. Web directories were present before the invention of search engine. The popularity of web directories were also came before the search engines. Web directories are nothing but a directory form where different types of resources and information are gathered by human hand.

The resources are here various kinds of link which are arranged according to their names. It can be arranged alphabetically, name wise and differently. It is exactly like a directory setting where various collections of links to various site are collected or arranged maintaining some attributes and qualities. Web directories offer a search but it is not like the search of a search engine. If the search directories do not offer the search facility of some kind then it would be completely impossible to browse thousands of pages for computers. But it can not be a search engine in two ways.

Fundamentally most web directories are different from search engines as directories are edited by humans and URLs here are not collected by spiders but they are submitted by the site owners. The main advantage of Web directories is that no matter how clever spiders become, when there is a human to view and check the pages, there is a lesser chance that pages will be classified in the wrong categories. And the disadvantage with this difference is that the lists in web directories are sometime outdated because if there is no human being to edit and submit the directories then it will be outdated. You have to edit and check the submission unless it will be not working. But this is not that bad because search engines also deliver pages that do not exist anymore. And the other disadvantage with it is that sometimes you might have to wait half a year before being included in a search directory. Mainly these differences are occurred because it is not automatically maintained or mechanically maintained.

On the other hand the search engines are automatically maintained with out any help of human hand. As in web directories there is no hand of spiders that is why anyone should go there and submit the URLs to the search directories. The job of search engines is much easy and automatic but the job of web directories is not automatic but manually done. Once you are included in a particular directory, in most cases you can stay there as long as you wish to and wait for people and search engines to find you. The fact that a link to your site appears in a respectable Web directory is good because first, it is a backlink and second, you increase your visibility for spiders, which in turn raises your chance to be indexed by them.
