    1. aze: möcüzəvi il

    tarix boyu mükəmməl hadisələrin baş verdiyi illəri adlandırmaq üçün istifadə olunan latın sözü.

    məsələn, 1666-cı il möcüzəvi ildir çünki eyni ildə isaak nyuton klassik fizikanın, ali riyaziyyatın, optikanın əsaslarını qoyur və eyni zamanda da qravitasiya qüvvəsini kəşf edir. həmin il haqda nyuton bunları yazıb:

    "In the beginning of the year 1665 I found the Method of approximating series & the Rule for reducing any dignity of any Binomial into such a series. The same year in May I found the method of Tangents of Gregory & Slusius, & in November had the direct method of fluxions & the next year in January had the Theory of Colors & in May following I had entrance into the inverse method of fluxions. And the same year I began to think of gravity extending to the orb of the Moon & (having found out how to estimate the force with which a globe revolving within a sphere presses the surface of the sphere) from Kepler's rule of the periodical times of the Planets being in sesquialterate proportion of their distances from the centers of their Orbs, I deduced that the forces which keep the Planets in their Orbs must be reciprocally as the squares of their distances from the centers about which they revolve: and thereby compared the force requisite to keep the Moon in her Orb with the force of gravity at the surface of the earth, and found them answer pretty nearly. All this was in the two plague years of 1665 and 1666. For in those days I was in the prime of my age of invention & minded Mathematics & Philosophy more than at any time since."
