“Can tech companies really offer better experiences than the taqueria, flower shop or dry cleaner down the street, while taking a cut for themselves? Not necessarily. Quality control is a challenge when the supervisor is just software.

“The idea is not just to teach city governments new techniques on harvesting open data to tackle urban problems and measure performance, but to replicate successful approaches that are already out there.“Read more

Until 2006 our Solar System consisted essentially of a star, planets, moons, and very much smaller bodies known as asteroids and comets. In 2006 the International Astronomical Union’s (IAU) Division III Working Committee addressed scientific issues and the Planet Definition Committee address cultural and social issues with regard to planet classifications. They introduced the “pluton” for bodies similar to planets but much smaller.

The IAU set down three rules to differentiate between planets and dwarf planets. First, the object must be in orbit around a star, while not being itself a star. Second, the object must be large enough (or more technically correct, massive enough) for its own gravity to pull it into a nearly spherical shape. The shape of objects with mass above 5×10²⁰ kg and diameter greater than 800 km would normally be determined by self-gravity, but all borderline cases would have to be established by observation.

Third, plutons or dwarf planets, are distinguished from classical planets in that they reside in orbits around the Sun that take longer than 200 years to complete (i.e. they orbit beyond Neptune). Plutons typically have orbits with a large orbital inclination and a large eccentricity (noncircular orbits). A planet should dominate its zone, either gravitationally, or in its size distribution. That is, the definition of “planet” should also include the requirement that it has cleared its orbital zone. Of course this third requirement automatically implies the second. Thus, one notes that planets and plutons are differentiated by the third requirement.

As we are soon to become a space faring civilization, we should rethink these cultural and social issues, differently, by subtraction or addition. By subtraction, if one breaks the other requirements? Comets and asteroids break the second requirement that the object must be large enough. Breaking the first requirement, which the IAU chose not address at the time, would have planet sized bodies not orbiting a star. From a socio-cultural perspective, one could suggest that these be named “darktons” (from dark + plutons). “Dark” because without orbiting a star, these objects would not be easily visible; “tons” because in deep space, without much matter, these bodies could not meet the third requirement of being able to dominate its zone.

Kyle VanHemert — WiredJaanus Kase isn’t sure we should teach every kid to code.

Wait, don’t grab your pitchfork just yet. He thinks it’s a perfectly noble idea, just that it ignores a basic fact: Programming as it exists today is tedious and a highly specialized skill—one that, frankly, not everyone is well-suited to. “Saying that everybody is a programmer, everybody must code, it’s dangerous,” he says. “It trivializes the art of programming. And it is an art—a craft.”

Rather than teach everyone to code, maybe it makes more sense to build tools that let some people side-step programming altogether? Read more

Ever wondered how the technology we use every day came into existence? Sure, an engineer designed it, a manufacturer produced it, and some savvy marketing helped sell you the product, but where did the ideas come from? Many famous inventions and household name technologies originated from research done by physicists, either as byproducts or direct application of their ideas. How does it all happen?

“So as a physicist, what do you actually do?”

Many people outside of academic physics departments often have this question, due to a lack of communication between general public and researchers. Read more

I read all the news about SpaceX’s Falcon 9 latest “failure” to land on an autonomous spaceport drone ship aka barge. I view these as trials to success. Here’s why.

1. Grasshopper Successes: The two videos below show that the early landing trials aka Grasshopper from several heights between 250m and 1,000m.

The lessons here are:

a) Pinpoint landing of a 1st stage rocket is technologically feasible.
