Comment Re:Communications? (Score 1) 143

OP, you're original post is still right with optical communication as well. Part of the problem lies within the fact that we don't know how much unseen light blocking dust is between here and there or other unfortunate large planet size non-radiating objects that we can't see. Something that lower frequency radio waves would not succumb to so easily.

My off the cuff guess is that you'd need to build a massive spaceship the size of an aircraft carrier if not more to generate the required power to transmit with the accompanying dish and electronics required. Try to get that into orbit affordably.

The communications technology to reach across 4.3 light years doesn't exist yet either. Look at the great lengths that we need to stay in touch with the Voyager aircraft just barely out of our solar system - launched 40 years ago.

And don't expect humans to survive all the hard radiation that's out there either. So it'd have to be a robot mission.

No. What you have now are left leaning "social justice warriors" calling *all* conservatives and anybody who has voted Republican "alt-right". Not just the Nazi's and the KKK racists.

Thus, they truly believe that any conservative talk is therefore "hate speech" and needs to be censored if at all possible. Many believe that violence is justified in order to silence the so called hate speech, and why antifa has in the past on both youtube and Patreon websites.

Youtube has evolved itself into a socialist/feminist monoculture internally which will demonetize or put in limited state anything that it disagrees with politically. It's what resulted in James Damore's firing.

I find it interesting that when Youtube started the "limited state" censorship, they censored a Nazi video, then they censored political videos from youtube user Black Pidgeon Speaks that was critical of Islam before they censored a bunch more Nazi videos. Do your research.

Submission + - Shaw Joins Bell in Calls to Censor the Internet In Canada (freezenet.ca)

Dangerous_Minds writes: Freezenet is reporting that Shaw, one of Canada's three largest ISPs, is joining calls to censor the Internet in the name of combating copyright infringement. The move comes just days after Bell was caught drafting a similar call. The call was made public in a submission to Canada's telecommunications regulator, the CRTC. Michael Geist notes that there is already growing political backlash to these suggestions, though the government is re-iterating comments that they support network neutrality.

Submission + - Industrial Arduino does it exist ?

jarleven writes: I'm a teacher in computer science and I believe Arduino is an excellent platform to learn both programming and electronics. My "colleagues" teaching automation on the other hand does not agree. They claim the Arduino platform is just a toy and it's not used in real world industrial applications.
I really believe the easy to use IDE is an excellent way to learn computational thinking and structured text programming, later the students can move on to PLCs and proprietary systems.
To convince them I really need to see the Arduino used in some real automated systems.
It would also be nice to see some PLCs with an ATmega328 inside (Yes I know the Arduino platform is a lot more than the ATmega :-) )

Submission + - Secret Link Uncovered Between Pure Math and Physics (quantamagazine.org)

ClickOnThis writes: Mathematics has been called both the queen and the handmaiden of the sciences. While arguably it is not a science (it does not draw conclusions from experiments) there is no question that science finds it useful. But occasionally, that utility runs in the other direction. Minhyong Kim at the University of Oxford has been working on one possible example of this. His work on finding rational-number solutions to Diophantine equations has led him to explore the application of principles from theoretical physics, such as the Principle of Least Action with the goal of discovering and exploiting new symmetries. From the article:

Over the past decade Kim has described a very new way of looking for patterns in the seemingly patternless world of rational numbers. He’s described this method in papers and conference talks and passed it along to students who now carry on the work themselves. Yet he has always held something back. He has a vision that animates his ideas, one based not in the pure world of numbers, but in concepts borrowed from physics. To Kim, rational solutions [to Diophantine equations] are somehow like the trajectory of light.

If the connection sounds fantastical it’s because it is, even to mathematicians. And for that reason, Kim long kept it to himself. “I was hiding it because for many years I was somewhat embarrassed by the physics connection,” he said. “Number theorists are a pretty tough-minded group of people, and influences from physics sometimes make them more skeptical of the mathematics.”
