When it comes to television viewing, what’s old is new again as an increasing number of Americans are dumping their cable boxes and going totally retro.

That’s right, the tried-and-true TV antenna — just digitally enhanced and minus the goofy bunny ears — is having a moment in the spotlight as people search for cheaper replacements for their cable and satellite TV packages.

One of the best articles I've ever read dealing with the history of the metric system:

The building in Sèvres is also home to the original kilogram, which sits under three bell jars in an underground vault and can only be accessed using three different keys, held by three different individuals. The small, cylindrical weight cast in platinum-iridium alloy is also, like the metre, due to be redefined in terms of nature – specifically the quantum-mechanical quantity known as the Planck constant – by the BIPM this November.

“Establishing a new basis for a new definition of the kilogram is a very big technological challenge. [It] was described at one point as the second most difficult experiment in the whole world, the first being discovering the Higgs Boson,” said Dr Martin Milton, director of the BIPM, who showed me the lab where the research is being conducted.

They read Marx, Lenin and Mao and formed student groups to discuss the progress of socialism. They investigated the treatment of the campus proletariat, including janitors, cooks and construction workers. They volunteered to help struggling rural families and dutifully recited the slogans of President Xi Jinping.

Then, after graduation, they attempted to put the party’s stated ideals into action, converging from across China last month on Huizhou, a city in the south, to organize labor unions at nearby factories and stage protests demanding greater protections for workers.

That’s when the party realized it had a problem.

The authorities moved quickly to crush the efforts of the young activists, detaining several dozen of them and scrubbing the internet of their calls for justice — but not before their example became a rallying cry for young people across the country unhappy with growing inequality, corruption and materialism in Chinese society.
But some in the party seem uneasy about the proliferation of student groups devoted to Marxism and Maoism, apparently worried that their calls for greater economic equality and worker rights could undermine China’s modern-day embrace of capitalist markets.

Reminds me of the mathematical study of curves of pursuit. I understand that, sometimes, the paths people want aren't completely obvious at the start. But it irritates me when paved paths don't respect the "obvious" path that people want, for instance a straight line between popular destinations. People want shortcuts!
Parks designers, if clever, would leave people to walk through those paths for few months. After paving them, they could claim they did the best for the public.

I ingenuously (sorry, naively!!) believed that those natural paths did exist only here!!!
