sagansense:

Our lovely blue planet, the Earth, is the only home we know. Venus is too hot. Mars is too cold. But the Earth is just right, a heaven for humans. After all, we evolved here. But our congenial climate may be unstable. We are perturbing our poor planet in serious and contradictory ways. Is there any danger of driving the environment of the Earth toward the planetary Hell of Venus or the global ice age of Mars? The simple answer is that nobody knows. The study of the global climate, the comparison of the Earth with other worlds, are subjects in their earliest stages of development. They are fields that are poorly and grudgingly funded. In our ignorance, we continue to push and pull, to pollute the atmosphere and brighten the land, oblivious of the fact that the long-term consequences are largely unknown. A few million years ago, when human beings first evolved on Earth, it was already a middle-aged world, 4.6 billion years along from the catastrophes and impetuosities of its youth. But we humans now represent a new and perhaps decisive factor. Our intelligence and our technology have given us the power to affect the climate. How will we use this power? Are we willing to tolerate ignorance and complacency in matters that affect the entire human family? Do we value short-term advantages above the welfare of the Earth? Or will we think on longer time scales, with concern for our children and our grandchildren, to understand and protect the complex life-support systems of our planet? The Earth is a tiny and fragile world. It needs to be cherished.
— Carl Sagan, Cosmos (1980)

Read it all. And keep in mind, as we move forward with our lives beyond this important (and hopefully historic) moment in our developing history, that Carl would have not only been right alongside those protesting around the world for global climate action, he would have most certainly been one of the key featured speakers at the 2014 U.N. Climate Summit.

MIT Robotic Cheetah

Oh HELL YES. Notice in the 2nd gif the “cheetah” runs untethered.

"MIT researchers have developed an algorithm for bounding that they’ve successfully implemented in a robotic cheetah."

AWESOME.

"The key to the bounding algorithm is in programming each of the robot’s legs to exert a certain amount of force in the split second during which it hits the ground, in order to maintain a given speed: In general, the faster the desired speed, the more force must be applied to propel the robot forward. In experiments the robot sprinted up to 10 mph and MIT researchers estimate the robot may eventually reach speeds of up to 30 mph.

This Rube Goldberg Machine Runs On Light
“Mirrors, lenses and reflective surfaces are combined to arresting effect in this commercial for au Hikari, a Japanese high-speed optical ISP. The machine’s optics work as one to reflect, focus, and diverge a single beam of light through a series of tasks, causing it to singe, melt and illuminate as it goes.”
