Assuan, die südlichste Stadt Ägyptens am ersten Nilkatarakt, nimmt neben Alexandria einen Ehrenplatz in der Wissenschaftsgeschichte ein. Diese beiden Orte ermöglichten eine der bekanntesten wissenschaftlichen Leistungen des Altertums: die erste, noch dazu bemerkenswert korrekte Berechnung des Umfangs der Erdkugel. Wohlgemerkt, wir sprechen vom 3. Jahrhundert vor Christus. Aber dies war eben die Epoche des Hellenismus, der ersten Hochblüte der exakten Wissenschaften. Diese wissenschaftliche Glanzleistung vollbrachte Eratosthenes von Kyrene, einer der berühmtesten griechischen Wissenschaftler. Die Frage ist nur: Wie kam er zu diesem staunenswerten Ergebnis? Konnte er überhaupt schon von der Kugelgestalt der Erde wissen? Und was hat das alles mit Christoph Kolumbus und der Entdeckung Amerikas zu tun? Auszug aus dem Buch "Was Sie schon immer über Ägypten wissen wollten" (erweitert). [mehr]

Der Komet - keiner hatte ihn kommen sehen, weil er bis zuletzt vom Licht der Sonne überstrahlt wurde. Für jede sinnvolle Gegenmaßnahme war es zu spät. Er würde die Erde gerade so eben nicht verfehlen und beispiellose Verwüstungen anrichten. "Nemesis", das göttliche Stragfericht, hatte man ihn getauft und keiner würde ihm entgehen. Er hatte sich auf´s Rad gesetzt und war zu seiner Ex-Familie gefahren, um die letzten Tage mit seinen Kindern verbringen zu können. Die Stimmung ist gedrückt, aber da kommt die Sprache auf Archimedes und die Dinge nehmen eine überraschende Wendung ... [mehr]

The square root of 3 is the positive real number that, when multiplied by itself, gives the number 3. It is more precisely called the principal square root of 3, to distinguish it from the negative number with the same property. It is denoted by \sqrt{3}. The first sixty digits of its decimal expansion are: 1.73205 08075 68877 29352 74463 41505 87236 69428 05253 81038 06280 5580... (sequence A002194 in OEIS) The rounded value of 1.732 is correct to within 0.01% of the actual value. A close fraction is \tfrac{97}{56} (1.732142857...). Archimedes reported (1351/780)2 > 3 > (265/153)2,[citation needed] accurate to 1/608400 (6-places) and 2/23409 (4-places), respectively. The square root of 3 is an irrational number. It is also known as Theodorus' constant, named after Theodorus of Cyrene. [mehr]

No Race Of Men, Scarcely An Individual, Is So Devoid Of Intelligence As Not To Recognize Power. Few Gifts Are More Courted. Power Is Almost As Varied As Character, And The Kind Of Power Most Desired Or Appreciated Is A Good Measure Of Character. The Pre-Eminence Furnished By Thew And Muscle Is Most Generally Recognized; But, As Men Reach Levels Above The Animal, Other Qualities Take The Lead. It Is Seen That The Immaterial Spirit Wins The Greater Triumphs,--That The Brainless Giant, Compared With The Dwarf Of Trained Intelligence, Can Accomplish Little. The Scale Runs On Into The Moral Qualities, Until At Last Humanity Has Given Its Sanction To The Divine Words, "Whosoever Will Be Chief Among You, Let Him Be Your Servant." The Few Who Have Successfully Grasped The Lever Of Which Archimedes Dreamed Are Those Who Have Attained The Highest Power To Serve The World. [mehr]

This book is a collection of 80 fundamental quotes and aphorisms of Nikola Tesla: Let the future tell the truth and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I really worked, is mine. Money does not represent such a value as men have placed upon it. All my money has been invested into experiments with which I have made new discoveries enabling mankind to have a little easier life. Archimedes was my ideal. I admired the works of artists, but to my mind, they were only shadows and semblances. The inventor, I thought, gives to the world creations which are palpable, which live and work. I have harnessed the cosmic rays and caused them to operate a motive device. The feeling is constantly growing on me that I had been the first to hear the greeting of one planet to another. It seems that I have always been ahead of my time. I had to wait nineteen years before Niagara was harnessed by my system, fifteen years before the basic inventions for wireless which I gave to the world in 1893 were applied universally. [mehr]
