How the American Dream has changed
The phrase ‘American Dream’ was officially coined just under 90 years ago in a book called The Epic of America by James Truslow Adams. He argued it was “that dream of a land in which life should be better and richer and fuller for everyone, with opportunity for each according to ability or achievement.”
Today: No single American Dream?
For some today the American Dream means a chance for fame and celebrity, while for others it means succeeding through the old adage of family values and hard work. Still others believe that the American Dream just represents a world closed to all but the elite with their wealth and contacts […]. Meanwhile, surveys have found that almost half of all millennials believe the American Dream is dead. In an ever-changing country, the idea of what the American Dream means to different people is changing too.

More Than Just Children's Books
Krumulus, a small bookstore in Germany, has everything a kid could want: parties, readings, concerts, plays, puppet shows, workshops and book clubs.
“I knew it was going to be very difficult to open a bookstore, everyone tells you you're crazy, there will be no future,” says Anna Morlinghaus, Krumulus's founder. Still, she wanted to try. A month before her third son was born, she opened the store in Berlin's Kreuzberg district.
BERLIN — On a recent Saturday afternoon, a hush fell in the bright, airy “reading-aloud” room at Krumulus, a small children's bookstore in Berlin, as Sven Wallrodt, one of the store's employees, stood up to speak. Brandishing a newly published illustrated children's book about the life of Johannes Gutenberg, the inventor of the printing press, he looked at the crowd of eager, mo stly school-aged children and their parents. “Welcome to this book presentation”, he said. “If you fall asleep, snore quietly”. Everyone laughed, but no one fell asleep. An hour later, the children followed Wallrodt down to the bookstore's basement workshop, whe re he showed them how Gutenberg fit leaden block letters into a metal plate. Then the children printed their own bookmark using a technique similar to Gutenberg's, everyone was thrilled.

Diverti-me imensamente com a história dos imbecis da web. Para quem não acompanhou, foi publicado em alguns jornais e também on-line que no curso de uma chamada lectio magistralis em Turim eu teria dito que a web está cheia de imbecis. É falso. A lectio era sobre um tema completamente diferente, mas isso mostra como as notícias circulam e se deformam entre os jornais e a web. A história dos imbecis surgiu numa conferência de imprensa durante a qual, respondendo a uma pergunta que não me lembro mais, fiz uma observação de puro bom senso. Admitindo que em 7 bilhões de habitantes exista uma taxa inevitável de imbecis, muitíssimos deles costumavam comunicar seus delírios aos íntimos ou aos amigos do bar - e assim suas opiniões permaneciam limitadas a um círculo restrito. Hoje uma parte consistente dessas pessoas tem a possibilidade de expressar as próprias opiniões nas redes sociais e, portanto, tais opiniões alcançam audiências altíssimas e se misturam com tantas outras ideias expressas por pessoas razoáveis.
[...]
É justo que a rede permita que mesmo quem não diz coisas sensatas se expresse, mas o excesso de besteira congestiona as linhas. E algumas reações descompensadas que vi na internet confirmam minha razoabilíssima tese. Alguém chegou a dizer que, para mim, as opiniões de um tolo e aquelas de um ganhador do prêmio Nobel têm a mesma evidência e não demorou para que se difundisse viralmente uma inútil discussão sobre o fato de eu ter ou não recebido um prêmio Nobel - sem que ninguém consultasse sequer a Wikipédia.
(Umberto Eco - Os imbecis e a imprensa responsável, 2017.)
Um objeto de massa m = 10 kg está suspenso por dois cabos que exercem
trações 
de mesma intensidade T, de modo que 
. As
trações exercidas pelos cabos estão dispostas conforme mostra a figura ao lado,
fazendo um ângulo de 30° com a direção horizontal. O objeto está em equilíbrio
estático e sujeito à atração gravitacional da Terra. Nesse local, a aceleração
gravitacional é g = 10 m/s2.
As medições no local são executadas por um observador inercial. Sabe-se que 1 V3 sen 30° = cos 60° = 1/2 , e que sen 60° = cos 30° = √3/2.
Levando em consideração os dados apresentados, assinale a alternativa que apresenta corretamente o valor do módulo da tração exercida por cada cabo.
