Although Segue 2 only contains about 1,000 stars, its total mass is about 600,000 solar masses. This means that the vast majority of the cluster’s mass is dark matter. In fact, so much of Segue 2 is dark matter that it is basically a clump of dark matter with a few old stars trapped in it. Still, Segue 2 is a gravitationally bound cluster of stars with a dark matter halo. Thus, it is a galaxy.

honestly, if your method can’t handle large uncertainties, it’s pretty useless for astronomy.

The only way to make the massive returns VCs like is to charge companies or governments. These are the only thing in our society rich enough to consistently feed the VC mouths. (this is why I strongly recommend against taking VC money — it’s much like adopting 15 children at once, it limits your options.) The only thing a social network can sell to companies are its users.

Čia ne atsakymas: „ir tu skiri jiems laiką, dėmesį ir eterį…“. Ir čia ne atsakymas: „taigi nx juos visus,amen“. Chroniško subjektyvios huinios nesprendimo pasekmė yra dvasinė mirtis

It takes years of research to make an interesting discovery, and takes much more than a tweet to communicate that discovery to people who are qualified to assess the validity of the discovery and determine the significance of its contribution. More importantly, there was a time when everyone understood that our knowledge was not the sort of thing that could be disseminated by op-ed or blogpost but required the long term mutual commitment of students and teachers in the classroom to be properly understood. What the panel was really doing was redefining what it means to know something. By abandoning “old school” lecturing and classroom discussion, and traditional academic prose, they were simply giving up on the sort of care and attention that makes it possible for us, as a culture, to understand complicated facts.

<…> we are now trying to get people believe things they can’t possibly understand. We are telling them what we think the truth is but without allowing them to engage critically with it. That’s precisely what our classrooms and journals are for. They are situations in which ideas can be presented along with their justifications, and where those justifications can be questioned before the proposed belief is adopted.

Because the Internet of Things is not about things on the internet. A world in which all our household gadgets can communicate with each other may sound vaguely useful, but it’s not really for us consumers. The Internet of Things serves the interests of the technology giants, in their epic wrangles with each other. And it is they who will turn the jargon of “smart cities” and “smart homes” into a self-fulfilling prophesy. In this piercing and provocative essay, Bruce Sterling tells the story of an idea that just won’t go away because there’s too much money to be made and a whole world to control.
