UCLA scientist discovers plate tectonics on Mars

For years, many scientists had thought that plate tectonics existed nowhere in our solar system but on Earth. Now, a UCLA scientist has discovered that the geological phenomenon, which involves the movement of huge crustal plates beneath a planet's surface, also exists on Mars.

"Mars is at a primitive stage of plate tectonics. It gives us a glimpse of how the early Earth may have looked and may help us understand how plate tectonics began on Earth," said An Yin, a UCLA professor of Earth and space sciences and the sole author of the new research.

Hollywood has Scientology. The tech world has the Singularity. I’m not conflating their beliefs or intellectual frameworks. I’m not calling them cults. I’m just saying, either you believe it or you don’t.

My first reaction was that these guys have been working way too hard.

Zapotec Digs in Mexico Show Clues to Rise and Fall

When it comes to pre-Columbian civilizations, the Aztec and Maya—known for their spectacular pyramids and temples, hieroglyphic writing systems, and elaborate, violent rituals—often overshadow the Zapotec, their less familiar counterparts centered in southern Mexico.

But the Zapotec also played a vital role in ancient Mesoamerica, and archaeologists are seeking new clues to the rise and fall of their culture and civilization, which flourished and declined in the Valley of Oaxaca at roughly the same time as the ancient Maya.

Tatăl sau, Antoniu, numit şi Cretanul , n-a fost om de frunte întreburile politice nici un nume faimos; a fost om de ispravă, însă, cinstit si tare filotim.cum se poate vedea din întâmplarea următoare: n-avea cine ştie ce bogăţii şi de aceea nevasta-l silea să fie mai strâns la mână. 

Veni odată un prieten şi-i ceru împrumut o sumă. El bani n-avea, dar îi porunci unui rob din casa să pună apă într-un pahar de argint şi să i-l aducă, îi aduse robul apa şi dânsul îşi săpuni barba ca şi cum ar fi vrut să se radă.îi făcu drum apoirobului din odaie după altă treabă şi-i dădu paharul prietenului zicându-i să facă ce-o vrea cu el. Văzu însă că se face multă zarvă în casă pentru paharul acela şică nevasta sa, mânioasă, e gata să pună la cazne robii, îi mărturisi fapta si-o rugă să-lierte.

Thucydides in London: Would the Ancient Greeks Approve of Our Modern Olympics?

The precious heritage of ancient Greece: The recognition that a life without excitement is a life scarcely worth living and that a life of excitement must inevitably be a life full of risks.
