    FIRST PATENT FOR GASOLINE ENGINE VEHICLE
    January 29, 1886 - Mannheim

    Karl Benz applied for a patent for his Benz Patent Motorwagen, a three-wheeler vehicle with a Benz-designed one-cylinder four-stroke gasoline engine. This patent, DRP-37435, “Fahrzeug mit Gasmotorenbetrieb,” (Vehicle with gas engine) is recognized as the world's first patent—regarded as the birth certificate—for a practical internal combustion engine powered automobile. Though the vehicle was awkward and frail, it incorporated some essential elements that would characterize the modern vehicle: electrical ignition, differential, mechanical valves, carburetor, engine cooling system, oil and grease cups for lubrication, and a braking system. The first public test-drive took place on 3 Jul 1886 in and around Mannheim. The patent was issued 2 Nov 1886, effective from the date of the application.

    DDT
    January 29, 1958 - America, U.S.A.

    The Boston Herald printed a letter from Olga Owens Huckins attacking DDT pesticide as dangerous. Huckins was a friend of Rachel Carson, and also sent a personal letter to her, which together prompted the writing of Carson's book Silent Spring, an early call for modern environmentalism. Carson collected research and data. She concluded that organic-pesticides built up in crops and sprayed crops, transferred to birds and other animals and was responsible for the poisoning of the surrounding fauna. Silent Spring asked important questions about balancing industrial and agricultural needs, progress, the protection of the environment and the quality of life. Carson's skilled writing awakened the conscience of America. It took until 1972 to get its use banned in the U.S.

  • 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.
