We’re not building clean energy anywhere near fast enough - useful reminder by @jtemple

Before the internet, publishing had been a distinction, with a limited number of people lucky, talented or wealthy enough to share ideas or images with a wide audience. After the rise of social media, publishing became a default, with non-participation the exception. There’s a problem with this rise in shared self-expression: we’ve all still got a constant and limited amount of attention available. For those creating content, this means the challenge now is not publishing your work, but finding an audience. The problem for those of us in the audience — i.e., all of us — is filtering through the information constantly coming at us.

We show that walls, and other obstructions with edges, can be exploited as naturally-occurring “cameras” that reveal the hidden scenes beyond them. In particular, we demonstrate methods for using the subtle spatio-temporal radiance variations that arise on the ground at the base of a wall’s edge to construct a one-dimensional video of the hidden scene behind the wall. The resulting technique can be used for a variety of applications in diverse physical settings. From standard RGB video recordings, we use edge cameras to recover 1-D videos that reveal the number and trajectories of people moving in an occluded scene. We further show that adjacent wall edges, such as those that arise in the case of an open doorway, yield a stereo camera from which the 2-D location of hidden, moving objects can be recovered. We demonstrate our technique in a number of indoor and outdoor environments involving varied floor surfaces and illumination conditions.

Today, a team that includes MIT and is led by the Carnegie Institution for Science has released the largest collection of observations made with a technique called radial velocity, to be used for hunting exoplanets. The huge dataset, taken over two decades by the W.M. Keck Observatory in Hawaii, is now available to the public, along with an open-source software package to process the data and an online tutorial. By making the data public and user-friendly, the scientists hope to draw fresh eyes to the observations, which encompass almost 61,000 measurements of more than 1,600 nearby stars.

additivism:

Researchers from MIT, the University of Sheffield and the Tokyo Institute of Technology joined forces for a project that reads like something out of a William Burroughs novel.

We humans are changing. We have become so intertwined with what we have created that we are no longer separate from it. We have outgrown the distinction between the natural and the artificial. We are what we make. We are our thoughts, whether they are created by our neurons, by our electronically augmented minds, by our technologically mediated social interactions, or by our machines themselves. We are our bodies, whether they are born in womb or test tube, our genes inherited or designed, organs augmented, repaired, transplanted, or manufactured. Our prosthetic enhancements are as simple as contact lenses and tattoos and as complex as robotic limbs and search engines. They are both functional and aesthetic. We are our perceptions, whether they are through our eyes and ears or our sensory-fused hyper-spectral sensors, processed as much by computers as by our own cortex. We are our institutions, cooperating super-organisms, entangled amalgams of people and machines with super-human intelligence, processing, sensing, deciding, acting. Our home planet is inhabited by both engineered organisms and evolved machines. Our very atmosphere is the emergent creation of forests, farms and factories. Empowered by the tools of the Enlightenment, connected by networked flows of freight and fuel and finance, by information and ideas, we are becoming something new. We are at the dawn of the Age of Entanglement.

There’s nothing wrong with the entrepreneurship-as-salvation gospel. Nothing wrong with teaching more people to code. But it’s impractical in the short term, and misses the greater point in the long term: We shouldn’t live in a universe of solipsistic startups…

Aaron was always and only working for (at least his conception of) the public good. He was brilliant, and funny. A kid genius. A soul, a conscience, the source of a question I have asked myself a million times: What would Aaron think? That person is gone today, driven to the edge by what a decent society would only call bullying. I get wrong. But I also get proportionality. And if you don’t get both, you don’t deserve to have the power of the United States government behind you.

We’ve all had those, “Aha!” moments when we finally get an idea. The problem is most of us don’t have a systematic way of finding them. The typical process a student goes through in learning is to follow a lectures, read a book and, failing that, grind out practice questions or reread notes. Without a system, understanding faster seems impossible. After all, the mental mechanisms for generating insights are completely hidden.
