הנה משהו שגוגל מצא, כמובן שלא
חשבת לשאול אותו, אבל כבר יאשת אותי. נתחיל בקטע
מאתר חופש (באמצע העמוד):
בנוסף, לא רק שאלוהים "מפספס" קצת, גם מעניין לראות לאיזה כיוון אלוהים מפספס. הטקסט הנדון אומר "אין חידושה של לבנה פחותה" ובפועל דווקא פחותה גם פחותה. בכ-0.7 שניה. אילו היה מעוניין רבן גמליאל כביכול להעביר את הדיוק המקסימלי באותה לשון ובאותו דיוק, היה משתמש מן הסתם בטקסט "אין חידושה של הלבנה עולה על..."
ונמשיך במשהו יותר מעמיק, במקרה שאכן האמת
מעניינת אותך, ולא נסיונות ניגוח:
Employing the technique of cyclic buildup, the Mayans, Babylonians, and Greeks were able to link the cycles of Venus and the moon with mathematical harmony (and proofs) (Aveni 94). This relation of the two cycles was significant, since Venus was universally regarded as an omen-bringer. The seasonal year was just as important to the Mayan and Babylonian (and Greek) agrarian civilizations, since the crop varied with the seasons. Accordingly, the "favored interval" of time measurement was a whole number exactly divisible by all three cycle periods (Aveni 94)--2920 days. The Greeks called this 2920-day cycle the "Octaeteris" (Aveni 95), probably because it is just about 8 solar years. It also encompasses 5 rounds of the Venus cycle, and just about 99 moons (95). Indeed, the lunar calendar builders looked further than these surface properties of even such a simple cyclic buildup, taking into account other rhythms in the natural environment and manipulating the periods to fit together with unquestionable mathematical rigor and precision (Aveni 98-99). A remarkable example is the Mayan discovery of eclipse cycles, which occur at the intersections of several other cycles--those of the moon, earth, and sun. The mathematical precision of the ancients' use of astronomy as a time-measuring device is seen in the Mayan Dresden Venus Table. It predicted 5 centuries to an accuracy of one day, based on the predictions given by the Mayan cyclic consummations (all focused on Venus, moon and sun, however) (99). The Babylonians developed a very similar table of Venus cycles based on a similar cyclic buildup in King Amizaduga's Tablet within two or three days' observational accuracy (Aveni 119).
