Conservation of momentum is more than "new physics". It's quite fundamental, thanks to Noether's Theorem: conservation of momentum is mathematically equivalent to "the laws of physics don't vary with spatial coordinates", that is, the X, Y, and Z axes can be "zeroed" anywhere, the choice of coordinates are arbitrary as long as their consistent. The universe would be a very strange place indeed if this weren't true, and furthermore we'd have noticed by now.

So, whatever's going on here, momentum is being conserved. Just how that's happening is the curious bit. It wasn't obvious until the early 1900s that light had momentum - maybe there's something else we're missing, or maybe this really is an actual "warp" drive that locally changes the metric of space (in a way different from GR) and momentum really isn't conserved. Somehow I doubt the latter is true.

Photons have momentum, but they don't have mass. You don't technically need mass, just conservation of momentum. The key is that the thrust produced that way is very small indeed, and that's apparently not the mechanism of this drive.

Sure, and had he appeared in person, your argument might make sense as the arrest of a fugitive might endanger others. But that's not what happened here: this was the city simply censoring content it disapproved of.

That's sort-of true. The government can regulate commerce in a way that it can't regulate speech. Obscenity laws, for example, can be constitutional if they prohibit selling specific content, as it's not the content that's illegal, it's the business practice. Even that is narrow, though, and can't apply to political speech. Clearly that's not what happened here -- the cops were just being dicks, are they usually are -- but you are more restricted when doing business than when simply speaking.

If the government imposes content-based restrictions on speech as a condition of issuing a permit, that's unambiguous government censorship. The exceptions in the US are few and narrow, and don't seem to apply here.

There's commonly-used software to build rainbow tables to do dictionary attacks. Obviously, individual words are there, but so are words with "leet speak" substitutions, words with short non-aplha prefixes and suffixes, and simple word combinations (and dates, of course, since those are still popular).

Anything beyond that makes you pretty safe from an attacker who has a list of thousands of hashed passwords, and is looking for the low-hanging fruit. However, for an attacker who wants your password specifically, the "correct horse battery staple" approach is well-known now, and the vocabulary of most native speakers isn't that large, it's best to think of a word as having the entropy of 3 random lowercase letters, or 2.5 random characters.

Still, string 4+ words together, or mix in a foreign word or a proper noun (other than a major city or sports team), and it remains a good approach.

If the web site requires some sort of login, and denies me the ability to use LastPass to manage that login, I do not use that website. No discussion, no arguments, my mind is entirely made up, closed, and locked on this point. I will find someone else to do business with who doesn't think they know better than I do how to secure my access to their site.

Why do you think that even matters? If it's down to a Bush/Clinton matchup, who WOULDN'T vote for the Trump candidate... hell, the result is in the name!

She also set a goal of installing half a billion new solar panels within her first term

Come on, even working four years straight there's no way she can install that many solar panels!

On the other hand, if she's doing that there's no way she has time to screw up the country like past presidents... OK, i'm in, as long as she keeps her promise to just install solar panels.

So in other words the original suggestion was as stupid as I made it sound in my sarcastic reply! Thanks for the confirmation!

After years of abuse, I just instantly close a website now if it decides an interstitial ad is needed. Regardless of where I am browsing.

No content is worth the suffering, no video can have enough cats to justify the anguish.

I have no idea if my own droopy matters at all, but I like to think window closure after interstitial presentation is a metric tracked and at least I am increasing it.

I can't imagine the twins seriously think that Bitcoin is going to go mainstream at this point in time. If anything, Bitcoin is fading from public view. No one has yet to come up with a compelling reason for consumers in developed economies to use BTC (beyond criminal activities, which is what most members of the public associate it with). Apple and Google are having trouble even getting people to adopt Apple Pay and Google Wallet ... what use could those same people have for BTC?

If Gemini ever does go on line, it will serve pretty much the same purpose as gold and silver exchanges; a way to separate the foolish from their money.

There is likely more radiation is food grown in various parts of America than from Fukushima.

In fact if you eat bananas at all from anywhere, you are absolutely getting way more radiation than from any produce grown in Fukushima.

There are so many natural sources of radiation you deal with every day, including the sun...

It's really a shame people can't be at all rational around radiation and apply the same kind of one-drop rule that racists use to justify their own crazy statements and thoughts.

able to self land safely at all times.

Really looking forward to the day when mechanical failure is utterly impossible and physics can be dialed down to any level desired!
