Το κράτος Ιανός: Το παράδειγμα των επενδύσεων στα φωτοβολταϊκά

Οποιαδήποτε στρατηγική για την υπέρβαση της οικονομικής κρίσης δεν μπορεί παρά να περιλαμβάνει ως πρωταρχικό στόχο την ανάπτυξη των επενδυτικών πρωτοβουλιών και μάλιστα των ιδιωτικών, τις οποίες το κράτος οφείλει να προωθεί και να ενισχύει με κάθε θεσμικό τρόπο.

China vs. the U.S.: It's Just as Cheap to Make Goods in the USA

An entire generation of Americans has come of age laboring under the assumption that the U.S. can’t compete in the manufacturing arena with low-cost competitors such as China and Brazil. That may have been true a decade ago, but it’s no longer true today.

Dont worry america you arent poorer than china

On Wednesday, the front page of the Financial Times declared that China stands poised to surpass the United States as the world's largest economy -- and to do so much sooner than anyone expected. Citing new data from a consortium of leading statistical agencies, the paper explains that when the Chinese and American economies are compared on the basis of purchasing power parity -- or how much a yuan or dollar can purchase in their respective countries -- China is on the threshold of overtaking the United States in terms of economic output as soon as this year.

The Mismeasure of Technology

Ricardo Hausmann

CAMBRIDGE – There is nothing better than fuzzy language to wreak havoc – or facilitate consensus. Ludwig Wittgenstein argued that philosophical puzzles are really just a consequence of the misuse of language. By contrast, the art of diplomacy is to find language that can hide disagreement.

Exoplanet Rotation Detected for the First Time

Astronomers have for the first time managed to detect the rotation of an extrasolar planet, by analysing the way its atmosphere filters light. This technique could also provide clues about planet formation. Ignas Snellen and his colleagues at Leiden University in the Netherlands report in Nature that a gaseous planet orbiting the star β Pictoris rotates at 25 kilometers per second at its equator — faster than any planet in the Solar System and about 50 times faster than Earth. A day on the planet, called β Pictoris b, lasts just over eight hours, even though the planet has a diameter more than 16 times that of Earth's and carries more than 3,000 times Earth's heft.
