NASA has just successfully completed the first test of an electromagnetic propulsion drive in vacuum. If the science behind this is right, this is one of the greatest conceptual leaps in human civilization; such a leap that we don't yet know exactly why it works.

I think this could be one of Randall's best yet. #xkcd

Hugo Chavez, like José Martí, Túpac Amaru, Pablo Neruda, Che Guevara, like Fidel Castro and Gabriel García Márquez, the last remaining voices of their generation, and like his hero Simón Bolívar, will enter into the mythology of Latin American folklore. This was the opinion of Colombian writer William Ospina in a column he wrote for El Espectador in January, and it is an opinion I share. In that column he described Chavez as a great man who has loved his people and tried to open the way to a little justice in a scandalously unjust continent. That is an opinion I also share.

Despite his reputation as a “dictator” in the United States (a four-time democratically elected dictator overwhelmingly supported by his own people no less), for the working poor in the rest of America (not just the United part of it) Chavez is regarded as a saviour. His use of oil revenue to invest in social programmes for the poor in his own country, low-interest loans for developing countries in the region, and even heating oil for low-income families in Europe and the US, has done infinitely more good than concentrating the wealth in the hands of a few individuals. Venezuela’s poverty rate has plummeted from 55.44% to 27.8% during his tenure while income inequality has increased in the rest of the world. As austerity threatens to sink Greece and Spain in the First World, Petrocaribe is one of the only lifelines keeping some emerging economies in the Caribbean afloat, including my own.

Does Venezuela have issues with press freedom and civil liberties? Of course. Does the United States? Yes, as I’m sure Bradley Manning will attest. Will Venezuela’s wealthy mourn Chavez’s passing? I’m sure they won’t. But, as Ospina put it once again, Venezuela is the only country in Latin America where the poor are happy and the rich are angry. That must mean something.

In Jamaica, there are statues of Simon Bolivar and high schools named after José Martí. I am certain that one day the name of Hugo Chavez will share that honour.

+Traci Loudin It's hard to say, although movements built around charismatic figures tend not to survive their leaders. Then again Chavismo/Bolivarianism is alive and well in Bolivia, Ecuador and Nicaragua, and judging by his still-strong support among the lower classes in last year's elections, I expect his party to win re-election in the next 30 days. The future after that depends on his chosen successor's management, barring external manipulation. The latter may have been why Maduro preemptively expelled both US military attaches (the US did back the 2002 attempted coup after all).

Charlie Brooker, my favourite techno-paranoiac, explains why micro-drones will murder you, your loved ones and the family dog sometime in the next two decades.

I think of Dyson spheres as the gated communities of the intergalactic neighbourhood. Makes perfect sense that they'd be hard to find.
Over fifty years ago, physicist Freeman Dyson proposed an awesome, if slightly insane, idea: That an advanced alien civilization might construct a massive, energy-harvesting sphere around its star, and bunk up inside.

Feast your eyes on these new pics of Methuselah, the oldest known star in our galaxy, a measly 190.1 light years away and a sprightly 14.5 billion years young. (Which is... quite a feat, considering the age of the universe is currently estimated at 13.772 billion years. Plus or minus 59000000 years or so.)

Some early proto-SF ideation from Anders Celsius (yes, Dr. °C himself) laying out his pitch for a space opera novel involving intergalactic war, planetary federations, life extension, transparent people and deep space dogfights. Way back in 1735.

Multi-dome lunar base being constructed, based on the 3D printing concept. Once assembled, the inflated domes are covered with a layer of 3D-printed lunar regolith by robots to help protect the occupants against space radiation and micrometeoroids

"Margaret Atwood is supposed to have summed up the gender power-differential like this: “Men are afraid women will laugh at them. Women are afraid men will kill them.”"

The above is perhaps the most succinct defence of feminism I've seen yet, and gets to the crux of why Men's Rights Activism, evangelical Christian complaints about being religiously persecuted, and Bill O'Reilly lamenting the death of Traditional America, are all manifestations of what this great article describes as "the distress of the privileged".

Every society inevitably reverts to a cultural default. This is natural and to be expected. The problem is when those who happen to fall within this default, say Protestant Christians in the United States, or heterosexual males in every country in the world, make the mistake of assuming (often unconsciously) that cultural default = supremacy. (Supremacy as in the inherently 'right' way to be.) To those who have slipped into this way of thinking, everyone else is just as free to either choose to join in doing things the 'right' way, or just agree to disagree. On the other hand any attempt to assert equality by others outside of this cultural default, even a simple "we're here too", is seen as an attempt to usurp the 'right' way to be... even though the truth is that the balance of power is overwhelmingly on the side of those of us who benefit from the profound privilege of being the cultural default.

Thus we get the War on Christmas, outcry about Chick-fil-A's "freedom of speech" (to fund anti-gay organizations) being suppressed, and the perennial question of "why isn't there an NAAWP".
