Archimedes :: essays research papers
                                        Archimedes S. Romano      Archimedes was a native of Syracuse, Sicily. Some authors have said that he visited Egypt and invented a device there now known as Archimedes' screw. This screw is a pump, still used in many parts of the world. When Archimedes was a young man, he studied with the descendants of Euclid in Alexandria. He was familiar with the mathematics used there, and he knew personally the mathematicians working there and he sent his results to Alexandria with personal messages. He regarded Conon of Samos, one of the mathematicians at Alexandria, very highly for his abilities as a mathematician and he also regarded him as a close friend.      In the preface to â€Å"On Spirals†Archimedes told a story about his friends in Alexandria. He said that he was in the habit of sending them statements of his latest theorems, but without giving proofs. Some of the mathematicians there claimed the results as their own so Archimedes said that on the last occasion when he sent them theorems he included two which were false. Other than in the prefaces to his works, information about Archimedes comes to us from a number of sources such as in stories from Plutarch, Livy, and others. Plutarch tells us that Archimedes was related to King Hieron II of Syracuse. Evidence of his friendship with the family of King Hieron II comes from the fact that â€Å"The Sandreckoner†was dedicated to Gelon, the son of King Hieron.      There are many of references to Archimedes in the writings of the time. He was probably the only mathematician of his time with such a high reputation. This is because he was not interest in new mathematical ideas but had invented war machines. They were particularly effective in the defense of Syracuse when it was attacked by the Romans and Marcellus. Plutarch writes in his work on Marcellus, the Roman commander, about how Archimedes' war machines were used against the Romans in the siege of 212 BC; â€Å"... when Archimedes began to ply his engines, he at once shot against the land forces all sorts of missile weapons, and immense masses of stone that came down with incredible noise and violence; against which no man could stand; for they knocked down those upon whom they fell in heaps, breaking all their ranks and files. In the meantime huge poles thrust out from the walls

We will all soon feel the connection to nature in a new way and start giving thanks to the specific plants that we love to eat and use as a part of our life, for example cotton an linen. It is really a gift from the plants to us. As they consist of conscious particles, they receive the gratitude from us by the particles’ mutual togetherness system.

The journey through the suffering and separation is soon over. The next years to come, we all will open our eyes for the true gifts of nature. It will lead us to new choices. When we chose to incarnate in physical body, one of our goals is to enjoy nature because this is the only planet where we can do it.

We live on a planet where we originally have developed from simple beings, like Darwin discovered. However, we have not developed because the strongest won like Darwin said. The human race is what it is because we were transformed from Neanderthals by creating masters that originally came from other civilizations in our galaxy thousands of years ago.

Simple Exister Verb Conjugations in French
The French verb for to exist is exister. This should be an easy one to remember because its so similar to the English word. Now, when you want to change it to the past tense existed, you will need to conjugate it. This is relatively simple and a quick lesson will show you how its done. Conjugating the French Verb Exister Exister is a regular -ER verb, which is the most common verb conjugation pattern found in the French language. This means that once you learn how to conjugate exister, you can apply the same endings to other verbs like à ©viter (to avoid) and emprunter (to borrow), among countless others. To conjugate exister into the present, future, or imperfect past tense, begin by identifying the verb stem: exist-. We will then add a new ending for each subject pronoun and tense. For instance, I exist is jexiste while we will exist is nous existerons. Its quite simple, particularly with a familiar word like this. To memorize these, practice them in context. Subject Present Future Imperfect j existe existerai existais tu existes existeras existais il existe existera existait nous existons existerons existions vous existez existerez existiez ils existent existeront existaient The Present Participle of Exister The present participle of exister is existant. Notice how this is as simple as adding -ant to the verb stem, which is how most present participles are formed. This is a verb and can also be an adjective, gerund, or noun in certain contexts. The Past Participle and Passà © Composà © The passà © composà ©Ã‚ is a common way to say the past tense existed in French. To form it, you need to attach the past participle existà ©Ã‚ to the subject pronoun and conjugate of avoir (an auxiliary, or helping, verb). It comes together quite easily. For instance, I existed is jai existà © and we existed is nous avons existà ©. More Simple Exister Conjugations to Learn Its important to concentrate on the exister forms above as theyre used most often. When youre comfortable with those, add the rest of these simple conjugations to your vocabulary. The subjunctive form is used when the action of existing is uncertain. Likewise, the conditional verb mood relies on something: if this happens, then this will exist. The passà © simple and imperfect subjunctive are reserved primarily for formal writing. Subject Subjunctive Conditional Pass Simple Imperfect Subjunctive j existe existerais existai existasse tu existes existerais existas existasses il existe existerait exista existt nous existions existerions existmes existassions vous existiez existeriez existtes existassiez ils existent existeraient existrent existassent To express exister in a short, direct statement, the imperative verb form may be used. When doing so, skip the subject pronoun as it is implied within the verb. Rather than tu existe, use existe alone. Imperative (tu) existe (nous) existons (vous) existez
