He went on to tell me about other adventures, including one where the ruins he discovered were so visually attractive and the surrounding jungle so lush that a Paramount Pictures locations executive he had made a connection with came to Cambodia within two weeks of the discovery for a preliminary study. A year later, they shot the film Lara Croft: Tomb Raider at that site.

We find in the Rig-Veda sexual imagery and also extensive use of numbers. According to historian of India John McLeish: “From the time of their earliest civilizations, the inhabitants of the Indian subcontinent had a highly sophisticated awareness of numbers.”
McLeish further says that the people of Mohenjo Daro—one of the first known cities on the Indian subcontinent, part of the Indus Valley civilization, which flourished some 4,000 years ago—“used a simple decimal system and had methods of counting, weighing and measuring that were far more advanced than those of their contemporaries in Egypt, Babylonia, and Mycenean Greece. Vedic altars had to be built to exacting mathematical prescriptions; the correct dimensions and the right geometry were crucial."

I was surprised by what one of them said: “We don’t like to admit it, but our written language really originates from Aramaic.” This was unexpected. “Well,” the middle-aged scholar wearing a jacket and bow tie continued, “India had long-standing trade relations with the Middle East and with Greece, and Aramaic—the lingua franca of the ancient Near East—influenced the development of our own script.”

I eventually built a career as a mathematician and statistician. For several years, I was a professor of mathematics at the University of Alaska in Juneau, and there, in 1984, Debra and I got married just below the Mendenhall Glacier, surrounded by Douglas fir trees, with occasional brown bears coming in from the forest to feed on the salmon making their way up the Mendenhall River.

Phoenician is the oldest language in the Near East, and we know that Pythagoras traveled in this region and learned some of his early notions about mathematics from the Phoenicians and the Egyptians and their priests. Our letter A and the Hebrew letter aleph both derive from the Phoenician letter aluf, which means bull and was inspired by a stylized drawing of the head of a bull. This letter once stood for the number 1.

While he lay there suffering from an unknown illness—now believed to have been a parasitic liver infection; he would die at 32, in the prime of his career—Hardy came to visit him. Not knowing what to say, he remarked, “I came here in a taxi with a rather dull number: 1729.” At that moment, Ramanujan, weak as he was, jumped up in bed and exclaimed, “No, Hardy, no, Hardy! It is a very interesting number! It is the smallest number expressible as the sum of two cubes in two different ways.” Ramanujan just knew thousands of such facts about numbers and equations, and never bothered with derivations. He had no need to prove anything.

So for any set, the power set associated with it is always larger than the set itself. If there were a set containing everything, its power set would still be larger, obviating the assumption that the original set contained everything. “Everything is not everything,” as the monk had told me.

Albert Einstein tudásszomja olthatatlan volt. Hívő emberként a tudományt úgy tekintette, mint az isteni teremtés megismerési folyamatát. A mai tudósok nagy része is így van ezzel. Ők vezetik a kutatásokat, és próbálják megérteni a teremtett világ rejtélyeit. Mélyfilozófiai kérdéseket tesznek fel a világegyetem származásával, jövőjével és természetével kapcsolatban.

Amikor majd minden egyes tudományág támogatja a többi fejlődését, megérthetjük talán a természeti törvényeket és leírhatunk talán egy egyenletet, amely megközelíti – amennyire ez az embertől lehetséges – Isten egyenletét. Az egyenlettel a kezünkben meg tudjuk majd oldani a teremtés csodálatos rejtélyét. Lehet, hogy Isten éppen ezért küldött ide minket?

Aristotle wrote two-and-a-half millennia ago, “Or is it because men were born with ten fingers and so, because they possess the equivalent of pebbles to the number of their fingers, come to use this number for counting everything else as well?” And since we also have ten toes, early societies used these as well to count beyond ten. Remnants of such a base-20 number system that existed long ago can still be seen in French, through words such as quatre-vingt (four twenties) for 80.
