This view is much more usable than the official one. Thanks!

Looks like you're right: "1. You are welcome to post pre-submission versions or the original submitted version of the manuscript on a personal blog, a collaborative wiki or a preprint server at any time (but not subsequent pre-acc

...but the effective storage time of the power recycling cavity in LIGO is about 1 second. This is a rather long time by optical standards, but I'd say it's a long way from "indefinitely".

Ah... a "can of light" as a practical energy storage mechanism. I think it's safe to say that this will remain a complete fantasy for the foreseeable future. Example: my laptop battery has an energy storage of about 100 Watt

I'm not sure this is a useful thing to say.

Even in a vacuum, you'll have diffractive losses unless the mirrors are infinitely large.

The air conditioners are, to a good approximation, just pumping energy out of the train cars that would be released anyway (i.e. the 100 Watts per passenger discussed below), plus whatever power they require themselves to run. Thus it seem

It sounds more crazy than cute to me.

I'm not sure how good a model a heat engine provides for internal combustion. A heat engine assumes a fixed "working fluid" operating between heat reservoirs. In an internal combustion engine, there isn't strictly a &q

If you assume a 2000 (kilo)calorie per day diet, you get: 2000 Kcal/day * (4.18 Joules/calorie) * (1 day/86400 seconds) = 96.75 Watts

Actually ALL of the energy is lost to heat.

A hardware problem is still a problem, though... Why would it be "written off"?

Yes, that stood out to me, too, because it is surprising and should be easily verifiable. Any Mailchimp users or employees care to comment?

Bitcoin... a monetary system that requires internet connectivity and CPU usage... in which every transaction is recorded forever and the database is replicated by all participants... is "off the grid"?

In general, anyone can edit or delete Wikipedia pages. If you are a "notable person" then you can expect your edits to be reverted, however; on the other hand, if you are not very notable, a page about you would probably not survi

> They shouldn't be spying in the first place. Should the U.S. spy agency (one of them, anyway) stop spying? Should the U.S. disband its spy agencies? Is there a role for "spying" in this age?

There's a big difference between a declaration and a proof.

Mail (i.e. the envelope) is scanned for address decoding. I believe the orange barcode is an index into the database of mail pieces and associated decoded address. Although this has a completely legitimate rationale in facilitating the de

Hm, really? I think I agree that "that" is better here, but I'm not yet convinced that "which" doesn't also work. If we truncate the sentence to "Nitpicker is a language style checker," it is still a

Meh - your comment history is relatively sophomoric.
