Humor has nothing to do with the incorrect definition of the number of dimensions of an object.

Which is why I mentioned your pedantry.

Let me draw you a diagram _________________

That is a two dimensional non-solid object since is has a height, one pixel, and a width, more than one pixel.

In fact, since it's drawn with electrons, it's got depth too. Actually, since it's drawn as pixels on your screen, which by now are probably discrete LED components, it's much more than that.

It's a signal which causes a series of diodes to emit a color which your eyes perceive as a straight black line -- in reality, it's none of those things either.

Look, you can be as pedantic, reductionist, and anal retentive about this as you like .. it's not contributing anything to this.

For purpose of explaining this and discussing it, they defined a plane in terms of this sheet of atoms with this particular layout.

That's it. There's no mathematical chicanery going on, and everybody knows it's not, strictly speaking, either a plane or a 2D structure. But it's got some characteristics of a plane, and, for purposes of discussion, is being treated as a 2D structure.

Because, if they had to say this 3-atom thick sheet of interlocking atoms which demonstrates some characteristics of planarity, and allow us to connect them together while maintaining the same type of planarity it would get awfully tedious.

In reality, it's probably not much different than LEGO.

Seriously, get over it. It's almost impossible to discuss this kind of thing without it turning into a tongue twister unless you come up with some form of metaphor.

The rest of this ... it's purely bullshit and pedantry by anal retentive people who need to demonstrate they remember something from math class.

Yes, excellent, from a mathematical perspective it's not 2D. But, for purposes of discussion of these material properties, they're calling it a plane.

You would think that scientists would be more accurate with their articulation of complex concepts.

Well, apparently they've defined a plane to be 3 atoms thick, and have grossly understimated the collective anal retentiveness of the people reading the article.

Dude, seriously, it's a dumbed down metaphor written for a press release.

From the parts of the paper which are available without subscription:

The junctions, grown by lateral heteroepitaxy using physical vapour transport7, are visible in an optical microscope and show enhanced photoluminescence. Atomically resolved transmission electron microscopy reveals that their structure is an undistorted honeycomb lattice in which substitution of one transition metal by another occurs across the interface.

I'm quite sure they're not idiots who really think this is a freakin' 2D plane.

TFA isn't the actual scientific paper, it's the press release intended for the public.

Now, unclench a little, you're gonna hurt yourself. :-P

While your pedantry skills are excellent, and your mathematical skills are pretty good ... I think you need to have your humor unit recalibrated, you seem to be a little out of phase.

I am perfectly aware of the fact that it isn't really a line on a plane in a strict mathematical sense ... heck, I even referenced the thickness of the ink and the fact that the paper has a surface.

Let me draw you a diagram _________________ ;-)

Now, what is the depth (stated in microns / femptofortnight) of the above line?

After about 15 minutes of this I couldn't take it anymore and I looked at the girl and said "Go ahead and punch this guy in the nose, and then ask him whether he still wonders whether you're a figment of your imagination."

LOL ... how do you know it actually happened, and you didn't just imagine it?

Which is precisely the problem with these kinds of postulates, they're completely unknowable, and pretty much stand on their own absurdity.

Because, I could have just imagined typing this, for instance. In which case I'm imagining me imagining you imagining what you did on the bus with the guy I'm imagining you imagining, when I should be trying to imagine the college girl.

And then it just becomes stupid, or, at least, I imagine it does. :-P

Metaphysics has to stop somewhere, otherwise it becomes drivel, which as far as I recall, most metaphysics is.

IF this is a simulated world, there is no reason to assume the rules in the simulation are the same as the ones of the world in which the simulation is running.

You know (and I mean no disrespect here), some of these topics become completely indistinguishable from college nights with way too many bong hits.

Sometimes these things become quite meta.

But what if the simulation is running inside of a simulation? You'd be all like "woah" and shit. And if that was inside of a simulation ... I think it would become Horton Hears a Who.

Yo, Dawg, I hear you like simulations ...

You *do* realize that the equatorial zone is generally tropical, wet as heck, and quite a bit warmer than everywhere else, yes? And that plants thrive on CO2?

Doesn't follow that making it warmer will make it drier. That doesn't seem to be how it works. Drier happens when water sources go away. There's no reasonable postulate for that which would apply to most equatorial regions.

Nah, it's almost certain to be big cats. Perfect apex predators. They can deal with heat, cold, wind; they can kill anything, climb like crazy, swim, they're fast as hell, stronger than just about anything, they instinctively use available terrain features for cover and shelter, they come equipped with deadly weapons, and they're very smart and wily. Common mutations already include thumbs and other extra digits, and they have a short enough breeding and maturation cycle that populations can recover in a very short time span, given only that mankind isn't around to defeat them using already developed technology.

Is it sane, given foreknowledge of your own demise and the power to avert it, to charge full-steam-ahead toward that demise

It's not my demise; it is the demise of others, sometime in the future. I fully expect to live out the rest of my life comfortably. I rather suspect that's the same set of conditions you face when you describe these worst case scenarios to others. Some of us are sensitive to the woes of future persons, some of us are not. But it's always at least one step removed from today's reality.

In the USA, just look at the number of people who would let the financially low performing suffer the slings and arrows of disease and injury without any particular concern or guilt; you can measure that directly by the resistance to the ACA, which remains substantial, even though it's working out pretty well if you actually take the time to look at the numbers. When people don't concern themselves with the other people in town, who are there and suffering right now, isn't it a bit optimistic to expect them to concern themselves with some abstract, unknown set of people who will exist after most of them have died anyway?

You're better off looking to technology to solve this than compassionate outlooks among the citizenry.

I'm going to go back to watching the news now, where I can learn more about us shooting up Afghanistan for no particular reason other than to prop up our MI complex, as we've kind of worn out Iraq now. You know, because we care. We'd be in Africa "helping" them too, you know, if we needed more income. I'm sure their day will come, though. Both Africa and South America are deep future market resources for our weapons manufacturers. Caring. It's what we do!

I know how to engineer complex things. I looked at the eventual fix, and it should have been done long ago.

Furthermore, if regression tests are important (and they are), they need a suite of automated tests so those things aren't all being done manually.

Finally, it's not like the glibc team traditionally avoids breaking things.

I'd expect massive droughts in the equatorial zones

Why? Equatorial zones have a great deal of ocean water, which certainly isn't going to change. That water will evaporate faster, the atmosphere will contain more humidity, and therefore there will be more precipitation, if the average temperature is up a few degrees C. How does that constitute the precursors for anticipating equatorial droughts?

I can see marginal areas (US midwest, for instance) baking off the little bit of moisture they have and not reaching any threshold of precipitation, followed by dustbowls and so on, but at the equator? Why would droughts happen there?
