Submission + - Elon Musk: SpaceX will dominate long distance Internet traffic. 1

lpress writes: SpaceX's first Internet satellite constellation will consist of 4,425 satellites at an altitude of 1,110 to 1,325 km. At 1,110 km, the distance to the horizon is 3,923 km so each satellite will have a line-of-sight view of all others within 7,846 kilometers. They will communicate optically, forming an immense mesh network, cutting latency time. For example, a link from Los Angeles to the southern tip of Chile will take 5 fast optical hops as opposed to 14 slower cable hops.

Submission + - Social media 'bots' tried to influence the U.S. election. Germany may be next (sciencemag.org)

sciencehabit writes: With Germans going to the polls on 24 September to elect their new parliament, experts are watching closely for signs of automated propaganda on social networks. So far, bots—fake social media profiles that appear to be human users but are really driven by algorithms—seem less active than they did in the recent presidential elections in France and the United States, where some commentators believe Russia was seeking to boost right-wing candidates. But researchers sensitized by past elections are making the German contest a laboratory for studies of how to recognize bots and trace their effects. Teams are trawling tens of millions of tweets related to the German elections for signs that bots are exerting influence.

Submission + - Theory of Everything: Another big step? (cqgplus.com) 1

Raharazod writes: From their newsletter:

One of the most interesting features of the theory and framework, that we now present, is that it appears to rule out the space-time singularities purported to exist within black holes as well as the initial big bang singularity. If confirmed this will imply that black holes are not infinitely “deep” and that the big bang probably never happened — at least not as a bang.

As I have already discussed in previous newsletters the great unsolved problem in theoretical physics is how to reconcile Einsteins theory of general relativity with quantum theory. But there exist, in fact, a less famous but equally important problem, which is to understand what a quantum theory of fields actually is.

Imagine that you have been searching for ancient buildings with a tiny torchlight in the dark. And then, after much effort and many detours and disappointments, you finally discover an entrance — and the entrance you have found looks promising, it looks like the entrance to a palace, or perhaps a pyramid, but you don’t know yet, all you know is that at the end of the corridor that you have just entered you can see the faint contours of a number of doors and what you want to do now is to walk across the room and try all the doors, one after another, to see what’s behind them.
This is where Johannes and I are now. We have found an entrance and have walked in — and now we’re in the business of checking doors. For an explorer that is a good place to be.

Perhaps. I read what he wrote as saying that the differences between men and women are purely cultural, not genetic. I replied with details on the genetic difference. If that wasn't what he meant, then it's on him to clarify.

Again, I wasn't saying anything about aptitude for engineering, which, incidentally, neither did the memo in question. The memo spoke about the differing interest in pursuing it as a career between men and women and speculated on why that might be. The aptitude for engineering aspect was your own, apparently misconstrued, addition to the discussion.

Actually, I was responding specifically to i_ate_god who said "Women and men are culturally different, but that's culture, not genetics." I wasn't attempting to prove that that difference applies to career selection, though many other people here have already presented information to that end. But thanks for deliberately misconstruing what I said.
