THE INTERNET ANO GUTEMBERG

In our age, everything is the newest New Thing or the biggest Big Thing. Steve Case of America Online already calls the new century "the Internet Century, " and some authorities whisper that the Internet rivaIs the importance of Gutenberg' s invention of the printing press in the 15th century.

We suffer from historical amnesia.

Suppose you were born in 1900. You wouldn't yet watch movies, let alone global TV. Fewer than 10% of D.S. homes had phones, and fewer than 8% had electricity. Antibiotics hadn' t been discovered. As yet the Internet isn' t in the same league wi th these developments.

Each changed lifestyles and popular beliefs. The automobile suburbanized America and inaugurated mass traveI. Antibiotics, vaccines and public-health advances helped raise life expectancy from 46 in 1900 to 77 today. The explosion of prosperity - a consequence of electricity, other technologies and modern management shortened working hours and expanded leisure. Movies and TV transformed popular culture. As a matter of fact, the Internet is too young for anyone to foretell its ultimate significance.

Uma haste de comprimento inicial L_o = 59,0 cm tem uma extremidade fixa na parede e a outra extremidade presa a uma placa retangular (1) isolante de área da face A, que pode deslizar com atrito desprezível na superfície horizontal. Outra placa retangular (2) isolante, de mesma área da face, está fixa na superfície horizontal a, uma distância d = 17,7 cm da placa (1). As placas possuem revestimento metálico nas faces (área A) que se defrontam, formando assim um capacitor plano de placas paralelas a vácuo. A haste, que possui massa m = 30,0 gramas, calor específico médio c = 0,40 cal/g. °C e coeficiente de dilatação linear !$ \alpha = 5,0.1,0^{-4} /°C !$, é uniformemente aquecida até atingir uma temperatura tal que a nova capacitância do capacitor torna-se 20% maior. O calor fornecido, em kcal, por um aquecedor (não indicado na figura) à haste é

BIOLOGlCAL PASSPORT NABS CHEATING CYCLISTS

The contest between athletes who use performance-enhancing drugs and the authorities trying to catch them is much like a race itself. Each time a new drug test comes out, athletes and their doctors figure out a way to outsmart it.

But a new "biological passport" that measures blood and body chemistry over time may finally be putting a dent in sports doping.

Professional cycling is the first sport to embrace the relatively new test, and it's just nabbed its biggest catch: an Italian cyclist, Franco Pellizotti, who was one of the favorites to win this year's Giro d'Italia. The Giro d-Italia, a grueling three-week event second in size and importance only to the Tour de France, kicks off on Saturday.
