How observant are you?

Can you figure this out without using Google?
- Ken Morley
Why does the total area change by one unit simply by rearranging the pieces?
- Ken Morley
It's not actually a triangle. The red triangle and yellow triangle don't have the same proportions.
- Eivind
That is, the slight "convexity" of the bottom one accounts for the extra area.
- Eivind
Man, you are much more observant than I am Eivind. I could NOT figure it out... I had to peek. :)
- Ken Morley
I'm good at stuff like this :)
- Eivind
Nope. Still don't get it. All the components look exactly the same to me. Also, I don't see any curves to indicate "convexity"
- Slippy
It is fairly subtle.
- Ken Morley
It's not actually a curve, but the inclination is not the same on the red and the yellow triangles, Slippy. You're right the components are the same, though.
- Eivind
So the grid is a lie? Because the yellows both measure (5x2)/2 and the reds are both (8x3)/2 area.
- Slippy
Yes, slope of yellow is 2/5, but red is 3/8 (.400 vs .375).
- Ken Morley
Use the Yellow Triangle to measure the red one. They are not similar. Beautiful Trick. I will use it during my lessons
- Isola Virtuale
I still don't get it. The components occupy the same space, however you arrange them.
- Slippy
I guess that whole "99 IQ" thing must have been as accurate as I thought it was.
- Slippy
Yeah, good trick huh? :)
- Ken Morley
Not really. However you explain it, I can't see it. I just feel really thick.
- Slippy
It works better on paper to see the difference. You can hold it at an extreme angle and see that the hypotenuses are not the same. But you can see that they are different by seeing how the hypotenuse hits the grid differently in each (in the bottom triangle, the yellow, green and blue meet up right on a grid point or very close to it - the same point in the upper (5 from the left and 2 from the bottom) is below the grid point.

How the Titanic sank radio freedom - http://blog.mises.org/17635...
Gordon Saunders, Evan Brown and Elina Missanjelina liked this
"Most people regard amateur radio is a very niche hobby performed in basements on equipment that hasn’t changed much during the last 100 years. But this wasn’t always the case. As Ars Technica reports, during the early 20th century, wireless radio was the latest in high tech and popular songs and plays were written about radio boys who provided critical communications links. But it was not to last. Shortly after the Titanic disaster, many major newspapers accused “outside unrecognized stations” of spreading misinformation about the disaster. A few months later, The Radio Act of 1912 was passed, which for the first time imposed severe restrictions on non-commercrial operators. In 1927, the licensing requirements were extended to commercial operators as well. It later came out that the Senate Commerce Committee had the new law prepared well in advance and used the Titanic incident to gather public support for its passing. Of course, through all the regulations, the State was granted best frequencies and exempted from the licensing burden."
- Alex Scrivener
"So was the Radio Act of 1912 motivated by a concern for public safety, a desire by corporate media to squeeze out amateur competitors, a government power grab over an emerging medium, or a legitimate technical problem? We’ll never know for sure, but it is interesting that from the earliest days of radio to FDR’s thought police, to today’s “wardrobe malfunctions,” regulations of the airwaves has been as much to do with controlling information as technical challenges."

What's sad is that people are using the Fukushima accidents to try to curb the building of new plants. What we need to realize is that we need nuclear energy in our efforts to reduce our dependence on hydrocarbons and that if we don't build new plants using much safer designs we too could be looking at this level of catastrophe in this country...

Since we have around 24 plants that are of the exact same design as the Fukushima plants. They need to be replaced with newer models ASAP.

I'd just like to throw this out there. No private industry will take on the responsibility of a new plant without the full guarantee of the government. That means all this talk of safety is a little suspect. There is no safe energy source.
- Eric
True, but some sources are safer than others.
- Victor Ganata
They won't do it because it's a long uphill battle costing billions of dollars just to get a plant built, if you can even get one built. Even if I had 50 billion in the bank I probably wouldn't want to go through the hassle of building a nuclear power plant and how many entities out there have the cash necessary to build new plants? So no, the talk of safety isn't suspect. Corporations don't really care about safety, what they care about is profit and if the profits aren't there they won't build.
- Scoble, Alex Scoble
What rarely gets mentioned, at least here on FF, is conserving energy. Americans are incredibly wasteful with energy resources. But better that people in other places deal with pollution and radioactivity than that we give up our god-given right to leave the TV on when we're asleep or have lights on in every room of the house when we're only in one room.
- Spidra Webster
IMHO, The economic problem is not necessarily the actual cost of guarantee but the perceived cost of potential liability and government interference. Companies don't want to build a plant if the government will force them to shut it down before the bonds are paid off over something stupid and insurers don't want to deal with a raft of people suing because their life sucks and they might have gotten one thousandth of a banana-equivalent-dose.
- Wirehead
Also, my gut feel is that it's not really a problem with the BWR design, merely some details that weren't quite attended to properly in terms of standby power and stuff.
- Wirehead
Conservation only gets you so far. Even if we conserve 20% energy per person, that doesn't help much if the population grows 50%.
- Scoble, Alex Scoble
I disagree there, Wirehead. If it was a more modern design with passive cooling systems there wouldn't have been a problem at all in this instance.
- Scoble, Alex Scoble
Or insurance companies just don't want to pay up tons of money when something disastrous *does* occur. (I wonder how the liability issue will play out in Fukushima)
- Victor Ganata
Alex, Americans aren't really trying to conserve unless someone gives them strong monetary incentive to do so. They don't care that there are reasons other than monetary to be conserving. Plus, the planet really can't handle a 50% population growth of humans. We need to learn to live within our means.
- Spidra Webster
Thing is, Alex, the reactors would likely have survived the beyond-design-spec earthquake much better had there been reserve power. Even if it was just a matter of putting the diesel generators on stilts or something. That can be done in a year or less. Can't crank out 24 new reactors in a year or less, no matter how fast you try.
- Wirehead
The only way to effectively conserve resources is to limit population growth.
- Jemm
Alex- population growth doesn't go up faster when we conserve energy. Conserving energy will be a benefit no matter the population growth. Everyone seems to know the general concept behind how small the US population is but the extreme amount of energy and resource we use. Not many people seem to care.

I mean, yeah, I've always been a fan of the IFR design since grade school, but I've been working on large projects long enough to know that sometimes it's better to tweak what's already in production that has worked pretty damn well.
- Wirehead
It's not that population growth goes faster when we conserve, the point is that conservation alone doesn't deal with power generation needs of a growing society. And expecting our society to willingly slow down growth is a non-starter. It's just not happening.
- Scoble, Alex Scoble
Alex. The designs at Fukushima were touted as being safer at the time. And each time something happens to test that theory
- Melanie Reed
They were safer at the time, but those designs are now 40 years old. They could have been built like Chernobyl, you know. And then we'd be looking at a real disaster.
- Scoble, Alex Scoble
Somehow economies managed to grow before the advent of electricity. But if people are too selfish to get serious about conservation, then I expect the species will get what it deserves. Honestly, it's probably going to go that way anyway given the way our last century of shenanigans has kicked off the greenhouse effect.
- Spidra Webster
Spidra is correct. Economies did grow before electricity. We do use way too much. And that's a lot of what's behind this idea that we have to have so much power...and , ahem, do it cheaply. If Greed is running your system (and it is) it is always going to be pushed to the price the market will bear. Resources become scarce through both over use and created belief.
- Melanie Reed
What about the forests of Europe that were cut down to fuel growth so fast that we were rescued from collapse by coal? No, our history as civilized humans is a story of switching from one source of limited energy to another to fuel growth. It is only recently that we had the ability to ask if it was necessary to expand quite so quickly and to do so in a way that reduces our need to find something more efficient to draw energy from.

That's a nice article, but I disagree with your assertion that it means nuclear power isn't practical.

We've already done that, Johnny. See "shoreham Nuclear power plant" on Long island - cost a mint to put up, then they realized, should anything go wrong, there's no escape route since it's at the juncture of Long island and New York/mainland US.

"There is no safe energy source" is pure BS. 18% of our utility's power comes from renewable sources, most of them absolutely safe (OK, I suppose a set of solar panels could fall on you in an earthquake)... And, you know, Californians have been reducing per-cap energy usage for years. Realistically, though, need a mix--which probably includes nuclear. BUT we also need a lot more renewable/non-nuke.
- Walt Crawford
The chemical processes used to manufacture solar panels are not entirely benign. And because you need so much surface area, it can completely disrupt ecosystems. That's what the fight over the Mojave Desert solar facility is about. Everything has an environmental impact.
- Victor Ganata
Almost everything of an industrial and technological production does. Agreed, Victor. It's been a subject of many science fiction stories where whole cultures have decided to forgo these types of lifestyle solutions. But generally they only decide to do it when brought almost to the point of extinction.

It's not pure BS, Walt, but I agree that we need to use all clean technologies at our disposal and need to do a lot more research in to alternatives in order to combat the problem.

OK: Impure BS. Sure, Victor: *existing* has environmental impact. If you tell me my thin-film 100% recyclable rooftop solar panels are environmentally disruptive, I'm not sure how I'd respond. And I do agree with Alex: We need nuclear in the mix.
- Walt Crawford
Ok, 24 plants at 2011 list prices.... whos got a calculator?
- Roberto Bonini
It gets cheaper in bulk. The thing that makes nuclear reactors, rockets, and a few other pieces of our future expensive isn't that shaping a giant piece of steel into a reactor core or a giant piece of aluminum into a rocket isn't that you are using elaborate amounts of material, it's that nobody wants to order a 24 pack of identical nuclear reactors with options for bunches more.
- Wirehead
Very little the government buys fits in that category these days.
- Scoble, Alex Scoble
Well, the F-35's and F-22's are great examples, actually. They were sold at a particular per-plane unit price with a given order size. The assembly line is built under the assumption that they will build planes at a given rate for a given amount of time. And then the government cuts the order size or reduces the rate, which then causes the per-plane unit price to shoot up. Furthermore, it shoots up even higher than what they'd pay if they'd just made a smaller, slower order in the first place.

My concern is about what we do with the nuclear waste. There doesn't seem to be a solution and that's (obviously) way more likely than an accident.
- amygeek
There is a solution, amygeek. It's just illegal in the US. Recover excess fissionables from the waste with today's technology, the remaining crap is dangerous for a few centuries before it's less radioactive than the ore from which it came. Run the remaining crap through an accelerated reactor (which is, honestly, tomorrow's technology, although it's looking practical) and you are talking about decades, not centuries.
- Wirehead
There are two points that need to be made: First, reprocessed reactor fuel has too much Plutonium-240 to be used for nuclear weaponry. Second, science class teaches you the fact of what a half-life is, but not what it means. The stuff that's really really radioactive and scary that makes reactor fuel not safe for the kitchen has a short half-life. The stuff that's barely radioactive has a long half-life. There are no long-half-life substances that are also radioactive.

by 'really scary', do you mean "dead in a day" or "cancer in 5-10 years"?

An atom decays by emitting a radioactive particle. The more likely it is to emit that particle, the more radiation a chunk of it will emit, therefore the shorter the half-life. "Dead in a day" has a shorter half-life than "cancer in 5-10 years", assuming similar quantities. It would take a lot of U-238 to be harmful because it has a very very long half-life. A small amount of I-131 is going to be really harmful, but it's also going to be mostly gone in weeks.

Are you sure that reprocessing is illegal in the US? I read that there are plants being built here to do just that.

The thing with iodine-131 (and to a lesser extent, cesium-137) is that it can get incorporated into the body and can actually be concentrated. It's temporary (their pharmacokinetic half-lives are only a few days) but it is long enough to cause damage.
- Victor Ganata
True, Victor. Nontheless, I'm not keen on sitting near iodine-131 or cesium-137, even if carefully prevented from ingestion. Whereas, I own some pieces of uranium glass. Alex, unless you know something I don't, Carter banned reprocessing and nobody has un-banned it.

Can you find a link regarding him doing that? There was no mention of it on Wikipedia, but my dad has told me the same thing.
- Scoble, Alex Scoble
http://en.wikipedia.org/wiki... Ban was lifted by Reagan.
- Scoble, Alex Scoble
My impression was that the reason the U.S. didn't restart reprocessing was, again, cost. Private companies didn't think it would be worth it, and so the domestic tech has really languished, and no one is particularly excited about the idea of outsourcing it http://www.fas.org/sgp...

Let me summarize what we've concluded so far: WE'RE SCREWED (sorry that's just my American optimism talking).

Essentially, if we want nuclear power with a decent margin of safety, the government has to subsidize it. I think that's a non-starter for a lot of people who espouse a certain ideology.
- Victor Ganata
except all the other energy systems also get subsidised - directly and indirectly

Awesome video of Shuttle's final launch. http://mashable.com/2011... I actually got to see a launch from Charleston several years ago. Awesome!

So Twitter taught me to press '.' to auto-scroll to the top and auto-refresh. Tumblr taught me to click on an image to auto-embiggen in my dashboard. FriendFeed taught me to Like posts. Facebook taught me to Like individual comments.

I often look for the "Hide" button on Twitter and Tumblr.
- John (bird whisperer)
Oh, I forgot about "Hide" Facebook has it too! All these sites need to all do the same thing but different. But the same. Um.... yeah.
- Zulema ⋅ spicy cocoa tart
Tumblr especially could use a "Hide" button.
- John (bird whisperer)
I just keep scrolling and I've enabled pagination so I just go to the next page. Really obnoxious Tumblr's just get blocked!

Saying IPv6 has "trillions" of addresses is like saying there are thousands of stars in the universe.
