All of these are available in quantity. Bromine is available in tank-car lots. Iodine is available in tonne lots.

"Lead is also somewhat rare."

"Somewhat rare", perhaps, but it only sells for about $1/pound, and 8 million tonnes are produced annually.

"Actually, if that's what it's made of there will be huge supply problems."

Actually, you're totally wrong. Sorry.

"I once calculated that there is not enough lead on the planet to make enough batteries to store enough energy for overnight use."

Batteries use multiple heavy plates of solid lead. This is a micrometer scale thin film on a substrate. There's a difference.

Very close. The first beat comes in a little bit too soon to be 7/8... try tapping it out and you'll notice. Tapping with your first two taps on the first two drum hits will get you the right tempo.

The reason that it can sound so close to 7/8 is because 7/8 = 14/16, which is only one sixteenth off of 13/16.

> "...it's hard to classify their actions from a moral standpoint as something other than stealing."

Once copyright was a deal in which my tax money was used to protect a limited monopoly, and in return I could use the art after the monopoly expired. Now it is corrupted so that once the time has expired, the written language is not commonly understandable. The recorded music and video will have fully deteriorated in their stored medium. The games and software won't run.

It is thus hard to classify their actions from a moral standpoint as something other than stealing. They steal my money to support a stolen copyright deal, and I do not accept it. The deal should be ignored and the thieves should be held responsible for their actions.

One of the harder exercises I had attempted in my linear algebra course was the "connected tanks of water and salt".

After searching for the solution, I found this awesome resource that combines linear algebra, differential equations and graph theory to model salt flows in various networks of tanks.

I don't know about the Navy but I was at an airbase in Afghanistan and some people were feeding a cat that was hanging around our building. An email went out ordering people to not feed the cat. As an incentive to comply the NCO in charge of the area said that if the cat feeding didn't stop it would be killed, not sure if he was serious but they weren't pleased with the prospect of having a cat around.
Do you mean that this wasn't the official charge? Because I'm sure the official charge was something else.
I'm all for cracking down on for-profit colleges that have low graduation rates and offer poor career prospects.
However, that's only one aspect of the problem. There are also students who are well prepared and go to good schools but still manage to rack up crippling debt. There are a lot of people who have gone into a lot of debt to get, say, a law degree but their earnings aren't nearly sufficient to handle their debt.
> The pro-nuclear crowd was arguing, as it was happening, that this could never occur. The cores would never breach the containment vessels, they said.

As mentioned in the other comment, the cores breached the reactor vessels, which is what didn't happen at TMI.

On the other hand, that did happen at Chernobyl (and explosively, to boot), so I'm not sure why people would be arguing that it's impossible or that it has never happened before. Unless possibly they mean that such a thing had never happened at a Western-style BWR or PWR reactor, which is at least closer to the truth.

But either way, this is all part of the problem with these debates. Pro-nuclear advocates generally say stuff which is true in a very precise, jargonistic way, which then gets either immediately mis-interpreted, or mis-interpreted 3 years later in a way which makes them out to be liars.

It would be like a computer hacker saying that it's impossible to get a security vulnerability from buffer overflow if you use a language that always manages memory, and then that managed language suffers a vuln from memory corruption instead. Laymen three years later would only remember "impossible to get security vulnerability from managed memory"...
NEVER ask a police officer for his/her badge number.

I can believe that this is good advice.

But I also have to mention that "get the officer's badge number" has been the generic advise given to people protesting/aiming-to-stop police misbehavior. And back twenty years ago, it might have been good advice (for all I know).

But here we have the quandary of every legal action people to resist the system within the system.

The poor people who passively take the punishment meted out to them have learned over a long, painful period that standing out and resisting gets them problems. And the cops learn ways to teach them this if behavior X becomes a serious impediment to their standard way of operating.

I know for serious charges, where the courts feel a need to keep the "plea bargaining" racket going, pleading not guilty is an invitation to an absurdly disproportionate sentence. It may be that people could actually get a chance at fairness if many began to plead not guilty (as the article suggests) but it seems likely the courts would begin "kicking butt and naming names" if such behavior slowed it down and that pleading guilty might become a similar invitation to abuse that asking an officer for his badge number seems to be now.

Which is a long way to say we need systemic reform that individual protest isn't enough to get.

"Unit morale dogs" were pretty common, and usually overlooked. A lot more common on the smaller bases. There were some charities to actually raise money to legally import them to the US afterward. There were also rabid dogs which bit people, got shot, got their heads cut off, and then got tested by the vets (including running them through CT machines when people got bored), so it really depended on behavior and context. I never saw cats in Afghanistan or Iraq, strangely, only dogs.

The Australians had a pet called Stretch at one of their bases in Hellmand/Kandahar area. On the cage, it said "I may look cute and cuddly, but I'm a fucking mongoose!".

Hmm, so you don't hear 7/8? Maybe I'm off, but do you hear the repeating percussion pattern on these notes (-- means an eighth rest)?

1 & -- & 3 -- 4 & -- -- 6 7

I hear that through the entire track, and counting with 7/8 has each new bar starting nicely on the first eighth note.

My vote is 7/8.

The other side of the argument is that this is clear proof we must never use nuclear energy for anything ever again, and instead continue burning our limitless supply of fossil fuels.

Well, that's a false dichotomy and representation right there.

It's possible to believe both that nuclear power isn't desirable and that fossil fuels are limited. Which from my experience a fair number of those opposed to nuclear do in fact believe.

Which rather undercuts your own credibility.

>>We're discussing here a group of people who started their careers dead smack in the middle of the dot-com bubble

This reminds of the Indian IT scene. Where today's so called managers/execs/leaders were just lucky to be in the path of immense inertia in the 90's.

Most of them probably have no experience at all, some of them as little as working in testing projects for a few months. They just had to be promoted because companies were growing 100% year on year, and the only way to get new managers were to promote existing people. People with as little as an year of experience from college became senior managers.

Now we have these people come and repeatedly lecture us 'We are so awesome, they had to make us VP's without doing any work at all'.
Interestingly, his former boss, US Navy Rear Admiral Hyman Rickover, who pretty much created nuclear power as a thing, expressed severe regrets and reservations at having relied on nuclear power for the navy and in its use for civilian power generation:

"I do not believe that nuclear power is worth it if it creates radiation. Then you might ask me why do I have nuclear powered ships. That is a necessary evil. I would sink them all. I am not proud of the part I played in it. I did it because it was necessary for the safety of this country. That's why I am such a great exponent of stopping this whole nonsense of war. Unfortunately limits — attempts to limit war have always failed. The lesson of history is when a war starts every nation will ultimately use whatever weapon it has available.... Every time you produce radiation, you produce something that has a certain half-life, in some cases for billions of years. I think the human race is going to wreck itself, and it is important that we get control of this horrible force and try to eliminate it."

I actually skimmed the book over before I took my first course in linear algebra (doing some of the exercises on my own, but certainly not all--I skipped anything that seemed too hard or just too boring during this reading). At that point, there were definitely parts of the book that were challenging to me, and I just jumped over them.

Then when I took the actual course, I more or less ignored the main course textbook and instead tried to tie whatever happened in the last lecture with what I found in Axler.

I considered Axler my secret weapon. It honestly felt like I had access to secret insights that trivialized the class and granted me the same intuition the professor had.

I also have your intuition but after thinking about a couple of the police's jobs I do understand how it could easily go the other way.

You have the somewhat obvious want of a visible police officer ranging an area to deter criminal activity such as shoplifting/vandalism/mugging.

But you also want the police in an area to deal with domestic dispute type crimes which you'd expect to increase at least linearly with density, possibly more so as the closer you are to your neighbors the more you may see them and the more their behavior may impact you. Which may mean that you need several more cops to respond to concurrent incidents even if the average rate of incidents is lower than what a single cop could deal with.

That's without getting in to any other issues such as bureaucracy needs/wants of larger departments. Or the odds of more dense areas being more culturally diverse/allowing higher differentials in income against distance.

So after that I think it would be quite hard to judge what would be required.

It depends whether the notes we're hearing are 8th notes or 16th notes. Given the style I'd say that they're fast 8ths rather than slow 16ths.

There was no official charge in the Stop-and-Frisk incident. I'm comparing that to a very professional (almost apologetic) Central Park trespassing ticket that ended up getting thrown out, as most of them do.

I'm assuming I was not charged with anything after the stop-and-frisk because they figured out I was probably a lot more trouble for them than I was worth. In this case, appearances were deceiving...what I was wearing at that time, due to the weather, screamed "punk kid/hipster" far more than the "Privileged Accountant who passes for White" clothing I had on underneath.

I believe everyone who's saying a person of color or otherwise underprivileged person would have had a much different outcome is 100% correct.

"Perhaps it's resentment of the widening income gap between 20-30 somethings in the tech industry and those in the service industry?"

Maybe. Because of the billionaire big winner image, people outside the industry see techies as very well off.

In fact, cops make a lot more on average -- benefits included -- than techies or programmers or engineers. In big American cities, cops are paid similar total compensation to doctors. The usual breakdown is 125k or so salary plus gold plated health care, various fancy bonuses and discounts and a pension plan that's worth more actuarially than all of the salary. Totals above $400k are not uncommon.

NYPD, as mentioned in op, is considered much more stingy than suburban NY departments so the cops in question may not be making quite that much.

Try counting "1 2 3 1 2 3 1 2 3 1 2 1 2" and you'll find that it fits perfectly.
I partially disagree, the main reason we have app stores is because it was a model that worked fairly well for the iPhone and everyone else badly copied it. The lockin effect is an ancillary benefit.
Assume the film is entirely lead (likely the limiting component -- as others have noted there is no shortage of bromine, chlorine, and iodine in the ocean) and 10 micrometers thick.

Lead has a density of 11,340 kg/m^3.

A ten micrometer thickness means that each m^2 of material will use about 0.11 kg of lead.

While the earth receives something like 1,000 watts/m^2 in full sun, other factors (e.g., night, clouds, different sun angles) mean that the mean is closer to 250 watts/m^2.

This stuff is expected to reach 20% efficiency, so each m^2 of collector will produce a mean output of 50 or so watts.

Human civilization as a whole produces about 15 terawatts of power, so replacing it would require about 300 billion square meters of collector.

At 0.11 kg/m^2, that would require about 33 billion kg of lead.

World production of lead is about 8 billion kg per year.

So, unless I messed up the arithmetic (please correct if so) total replacement of all existing power sources would require only about 4 years of lead output. Given that that will never happen (and even if it did, the time scale would be much longer than 4 years), it is safe to say that the availability of lead is not a limiting factor for this technology.
It's well north of that.

Had it been a slightly warmer day, this incident would have likely never occurred.

That being said, I think what's happening on the left coast is the widening income gap coupled with a context switch that the cops are still catching up to. There are a lot of kids who bleed entitlement, some of whom are quite wealthy and some of whom are dirt poor.
