Inside The U.S. Navy's Leadership School
The top level of Navy leadership is its admirals . There are 238
of them. They have responsibility for more than 390, 000 members of
the Navy and control an annual budget of more than $130 billion.
They are the equivalent of a corporate C–suite. Of the more than
3,000 captains who serve in the Navy, roughly 38––barely 1% ––make
the cut to admiral each year.
In 2001 the chief of naval operations––the Navy's CEO––asked
retired Vice Admiral Phil Quast, who had spent 38 years in the Navy,
to establish the program that became the Executive Learning Office.
"Of 238 admiral positions, fewer than 40 are concerned with actual
war fighting, " Quast notes. "The vast majority is doing jobs
analogous to that of a CEO, CTO, CFO, COO or other functional
business areas. Our job is to help them develop the business acumen
they need to run the business of the Navy as excellent stewards of
the public's money and its trust."

THE INTERNET AND 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 rivals 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 U.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 with these
developments .
Each changed lifestyles and popular beliefs. The automobile
suburbanized America and inaugurated mass travel. 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.

The turning tide for the turtles
With their exquisite shells, their smiling faces, their
deliberate movements, and their amazing sea–born agility, sea
turtles have always captured human imagination. Once severely
endangered, turtle populations are growing steadily thanks to
conservation projects worldwide. And with more than 8000 km of
coastline, large stretches of which are favorite nesting spots for
turtles, Brazil is one of the leaders in the race to protect them.

Dois pendulos constituídos por fios de massas desprezíveis e de
comprimento L = 2,0 m estão pendurados em um teto em dois pontos próximos
de tal modo que as esferas A e B, de raios desprezíveis, estejam muito
próximas, sem se tocarem. As massas das esferas valem mA =
0,10 kg e mB = 0,15 kg. Abandona–se a esfera A quando o fio forma um ângulo de 60°
com a vertical, estando a esfera B do outro pêndulo na posição de
equilíbrio. Sabendo que, após a colisão frontal, a altura máxima
alcançada pelo centro de massa do sistema, em relação à posição de
equilíbrio, é de 0,40 m, o coeficiente de restituição da colisão é
Um bloco é solto de certa altura sobre uma mola ideal vertical que
possui constante elástica K, como mostra a figura 1. O bloco passa a ficar
preso à mola (despreze as perdas nesta colisão) comprimindo–a até parar
