Later down the page, Wolfram issues a challenge: "It’s been years now, and I’d really like to see SMP run again. So here’s a challenge. This is the source for a C program encrypted like the SMP source code..."
Just wanted to call this out in case anyone wanted to try decrypting it :).
This paper is in Scientific Reports, which is published by Nature but is not regarded as a top-tier journal. It has an impact factor of 5.5 vs. 41 of Nature.
But I would say that "selling the science" occurs more often for high-profile journals because the authors need to convince the reviewers that the paper has a significant impact. Papers in more field-specific journals tend to write conservatively.
No, that's standard boilerplate these days in papers. You have to "sell" the science a bit to reviewers and connect your work to the broader picture. Those in the field usually ignore statements like this.
The images in this article are awful: generic shots and captions of a machine shop; a (possibly empty) black box that's supposed to be a testing machine. Where are the actual machines doing the tests? Where's the science?
That was the argument before Snowden, but we now know that the government passively records and stores as much information as possible on anyone. So they can build a secret file on anyone should they feel like it. And they'll use every piece of information at their disposal (private family life, shopping and travel habits, what websites you browse, what media you consume, etc.) to profile you. Ever download a copyrighted file or view pornography? That will be used against you.
True, but looking at the trend in energy density improvements in Li ion batteries, it's linear and seems like it would take more than 2 years to achieve a 2x improvement: http://www.batteryuniversity.com/images/parttwo-55h.gif
The problem with reducing the mass of the non-Li portion of the battery is that all of the practical candidates for the anode are metal oxides (e.g. Co, Fe, Mn oxides). Unless the whole metal oxide motif is replaced, you can't really achieve significant mass savings. There are research groups and startups working on alternate anode and cathode materials but there are tradeoffs in power density and safety. Also given that these approaches are still in the research phase, it'll take at least a couple of years before they reach commercial testing.
I agree with others here who recommend learning how to code.
But instead of chasing the latest trends in frameworks, I would recommend learning ruby on rails instead. It's a mature framework that is still very popular. Learning it instills good principles that you carry over when learning future frameworks.
