You imagine the equipment and personnel to record serial numbers of bills passing by were common back then. Let me give you a hint, as someone who was there...no, it wasn't.
Whether it was or wasn't common - the fact remains that criminals were traced and caught in that era using marked bills or serial numbers. Equally factual, is that the US Mint records the serial numbers of all the bills it destroys.
So, that none have ever shown up in circulation or to be destroyed can be taken as evidence that it's highly likely that none was ever spent.
If only they were working on a technology to cheaply bore tunnels, so they could make up for a lack of serial performance by making a lot of parallel lines.
One of those things that sound impressive to the generally clueless "because Elon!" crowd... But which makes very little sense when you do the math. (Hint: When you have to drill twenty plus tunnels and ten times the surface infrastructure - you aren't going to end up saving much money.)
The fact that it makes much smaller tunnels than standard boring machines is a large part of the cost-saving strategy (although not the only part). The Loop going into it on which people will travel up to 150 MPH is notable for being optimized to work in small spaces, as opposed to subway trains.
While the speed sounds impressive - previous articles have indicated that the Loop can only carry a fraction of the passengers per hour that a conventional subway can carry.
So, to do what you didn't do (answer the grandparent's question): The excitement is basically Because Elon.
So, you get a crater roughly the right size in that sort of rock if it is 2.5 km in diameter. You get 0.85 megatonnes equivalent energy, which is next to nothing. No significant global effect.
Your math is... way, way off - 8.47*10^5 megatons is 847,000 megatons, not.85 megatons.
Are we going to see school PTA's pulling $50k fundraisers to get the science class' cubesat in orbit?
Probably not - because $50k won't buy a launch. (A launch costs $5 million.) Just as with small payloads today, they'll have to wait to hitch a ride on someone else's launch.
It was overkill then, but I am not aware of a smaller helicopter carrier in service back then.
They had the Iwo Jima class LPH's, two of which (USS Guadalcanal (Gemini 10) and USS Guam (Gemini 11)) were used as Gemini recovery vessels. USS Guadalcanal also recovered Apollo 9, USS USS Iwo Jima recovered Apollo 13, USS New Orleans recovered Apollo 14, and USS Okinawa recovered Apollo 15. USS New Orleans also recovered Skylab 3, Skylab 4, and ASTP.
Looking at the Gemini/Apollo missions that were recovered by a full size carrier... One thing immediately leapt out at me - they were all older carriers, WW II leftovers of the Essex class. That's probably because they constituted over half the active carriers at the time more than anything else.
And now, we have a lot better idea of where the capsule is coming down.
According to Apollo By The Numbers the largest miss distance was 3 nautical miles. Most missions missed by no more than 2 nautical miles. The largest distance to the recovery vessel was 13 nautical miles on Apollo 11, the rest were under 4 nautical miles. I can't find any similar compilation for Gemini, but IIRC the numbers were generally similar. (Mercury was all over the place.)
Missing from the summary is the fact that Samasource is a non-profit focused specifically on exploiting some of the worlds poorest people for the benefit of some of the world's richest.
There, fixed that for you.
No skill/low skill/non transferable skill digital "jobs" aren't "opportunity". They're exploiting desperation for profit.
Before you jump on "Samasource is a non-profit", yeah, true. And completely irrelevant - because the companies that hire via Samasource aren't non-profit.
You sell what the customers want, or they buy from someplace else.
Very true. The problem is that the very noisy, very much in the minority, "fans" mistakenly believe they represent the customer. By and large, they don't.
. It all sounds good to 'not be a jerk' but how do topics like illegal immigration get honestly discussed in a PC way.
That's trivially easy. If you can't not act and talk like a racist, or react only based on fear, or not spread lies and disinformation... The problem isn't that we're unable have honest discussions. The problem is that you're a dishonest jackass who wouldn't recognize honesty and facts if they were standing in front of you.
The rest of your comment makes that abundantly clear - you're more interested in spreading the racist FUD about "being illegal" than in actual discussion.
The racist jerks that now rule Slashdot can go ahead and mod me down and prove me right. The problem isn't "PC culture" - the problem is folks like you.
If the helium concentration was high enough to affect phones this way, they're lucky it didn't displace too much oxygen and freaking kill people.
Yeah, there's a ton of holes in the story. In the linked article, he admits his test used a far higher concentration of He than would have been possible in the hospital. Plus, if you actually follow up on the kinks... you find the story doesn't tell the whole truth, there were other devices that experienced glitches. And someone else points out that all the Apple devices in question use inductive charging.
Do you understand how far this reasoning could be applied to? For example, you will not be allowed to sell your old iPhone, or iMac to somebody else, because it has Apple logo and you are not Apple and you are not allowed to use the Apple logo.
Nope, the courts have ruled many times that you have the ability to resell anything you own. (It's called the Doctrine of 1st Sale. Look it up.)
think Musk fits this mold. If a bus were to hit him tomorrow he'd go down in the history books as the most significant tech entrepreneur of our age; where as Bill Gates made a fortune catching the PC wave, Musk actually drove change in a way that Gates never did.
Yes, the tax breaks that drove Tesla and Solar City and the shift to commercial services that drove SpaceX have nothing to do with anything. Seriously, Musk caught waves too. He didn't force change, he latched onto circumstance.
A personal rant about Google here (tl;dr Google software is becoming as much as a pain as MS software) - I do the IT for a School and Google are getting just as user hostile as MS ever were. Their attitude is now "what we want matters more than what the users want" (Google got big by providing what users wanted, and Microsoft is getting smaller for ignoring this - e.g. MS browser share is now 3%. 3%! can you imagine that 15 years ago?).
Sure, we could and did imagine it 15 years ago... Though the appeal was still wending it's way through the courts, the suit that would eventually force Microsoft to unbundle Internet Exploder had already been won. What we expected however that an independent browser, such as Mozilla, would eventually win the Browser Wars. What we got, and did not expect, was that one corporate browser (IE) would eventually be replaced by another (Chrome).
I feel like the next hundred comments could each mention a different issue that played "a role" in google+'s demise.
I'll start: Invite-only rollout.
Yep. Being feature-incomplete compared to Facebook at the time didn't help either. It was essentially Twitter with screwy privacy settings and a crappy UI.
It used to be the domain of people who understood a little about it and cared about its future.
And had about.00001% of the functionality of the current internet.
And while I see the elitists bitching about the "new guys", I have to see one say they'd be happy with a stone age internet they so desperately defend.
Ironically, this is all happening just as Tesla is ramping up Model 3 production to break-even level, where they'll be able to start posting legitimate GAAP profits. If he can just contain his demons for a few more weeks, Tesla will be in a much better position, and the short-sellers will be less of a concern.
No, Tesla will be in pretty much the same position it is now... With a stock price far in excess of any reasonable value based on revenue and billions of dollars in bonds coming due over the next four years. (Bonds that Tesla is going to have a very hard time repaying, even if they do start making an actual profit on the Model 3.)
At least them Wiki folks can keep their servers humming along a bit longer
Yeah, instead of having fifteen years of operating capital in the bank, now they have fifteen and a couple of months. Seriously, despite they hype they generate with their annual begging campaigns the Wikimedia Foundation/Wikipedia are swimming in buckets of cash.
No banker or financier in the world with any kind of reputation would provide any kind of shady or "pretend" support. They know derned well the SEC would check, and they'd land in the dock right beside Musk.
We build the ISS and many other space stations without the Saturn V.
And people used to ride horses to cross the continent. Just because something was done one way once, doesn't mean it's an ideal way to do sometime and there's no room for improvement.
Either way, I wasn't advocating for a Saturn V sized booster. I was pointing out that they physical size you can loft has significant engineering impact on the size (and capability) of the modules. The smaller the module, the more of your mass budget that will be spent on your docking (berthing) and interconnection systems. That drives up your overall cost per lb of functional systems and means that a smaller "cheaper" launcher could end up costing you as much if not more per lb than a larger launcher. Real world engineering is complicated that way.
Well a sovereign wealth fund did agree to take Tesla private on reasonable terms.
Um, how about bullshit? A sovereign wealth fund agreed to talk about negotiating a deal that would fund taking Tesla private - but it doesn't appear to have gone any further.
Musk just wanted to be transparent with the shareholders.
Transparency requires telling the truth - Musk did not tell the truth. He did not have funding secured.

The Electron gets around this (to an extent), by jettisoning part of the battery pack during ascent. (But if jettisoning fails, the mission fails...)
Probably not - because $50k won't buy a launch. (A launch costs $5 million.) Just as with small payloads today, they'll have to wait to hitch a ride on someone else's launch.

It's funny - you think the stuff you know is hard, and the stuff you don't know is easy (or at least plausible).
Protip on the latter: It's hard too. Much harder than you think.

[massive amount of nutjob rantings snipped]
The precedents and rulings already exist - SEC regulations have the force of law.
You don't see that saying he had a deal when he didn't have a deal as something wrong? The SEC disagrees with you.
