The process to convert CO2 into long-chain hydrocarbons has been in use since the 1930s. It's not inefficient because it requires high heat. On the contrary, it produces excess heat, and must be actively cooled with water flowing through an internal heat-exchanger. The inefficiency lies in the need to create-and supply hydrogen, which requires some process such as electrolysis of water. Oh, and it does require high pressure, which costs energy. Oh and it does take energy to raise the concentration of CO2 to sufficient levels from the atmosphere while filtering out the nitrogen and oxygen. So it mostly makes more sense to start with a product like wood-gas, coal-gas or natural-gas, and then turn that into diesel. Not as interesting as pulling it from the air, but it does give you a carbon-neutral source of portable fuel, when you use plant material. It also ends up being similar to that whole "anything into oil" idea that Scientific American used to be crazy about, but turned out not to be price-competetive, and the smell of rotting turkey guys upset the neighbors.
Would it have been that hard to expand that initialism? I've got far too many TLAs floating around in my head to be able to figure out what context you are talking about. The inability to introduce a topic properly within a slashdot summary irks me more than all the other stuff people always moan about here.
I'm an outsider, so I've just gotta be misunderstanding something. The oxford nanopore website seems to be claiming that you can sequence an analyte in real time, with a $1000 startup fee and $900 or less for a consumable...It uses a nanoscopic hole with an enzyme around it that ratchets a DNA strand through one nucleotide pair at a time, the whole time, spitting out the results to your computer....I can't process this. How can it be this portable, simple, and cheap? How did we get so good at this stuff?
Every new keyboard I use, first thing I do is pluck the capslock key out so I don't hit it by mistake. I tape it to the back in case anyone else ever needs it. I basically never miss it.
I agree with this, but you really should've stated the reason. If public transportation was free, then poor people, who previously didn't go anywhere, would start using it. People who used to use it but either currently own or could afford a car would get disgusted by the increased volume and decreased quality of service, and would start using cars. People who previously drove would hear the horror stories about the mess that is public transportation, and thank their lucky stars that the only repercussion is a slightly increased level of traffic. One benefit this would have would be more poor people getting access to transportation to jobs or education.
I mean, it's gonna take me awhile to finish drawing this infinitely long line, but so far, it is touching the x access at every single point within the the set of real numbers.
Hmm, I've got Khan Academy agreeing with me too: https://www.khanacademy.org/ma... on his board at 3:16. But, what does he know, he's only one of the most highly regarded sources for learning mathematics online...I'm sure it was just a slip-up that no one seems to have successfully countered in his comments...
it approaches infinity if you start at one and get closer and closer and closer to 0. N/.00000001 is pretty high.
But it approaches negative infinity if you start at -1 and get closer and closer and closer to 0. N/-.00000000001 is pretty low.
because of this discontinuity...the largest discontinuity possible in fact, the actual value of N/0 cannot be any of these compromises. It has to not exist.
This video does a decent job of explaining the problem: Numberphile: The problem with zero" It tries to address the very question that OP is asking.
Division by zero isn't equal to zero. It isn't equal to positive infinity. It isn't equal to negative infinity. the value of any number divided by zero (including 0) is that it does not exist. After all, doesn't any number divided by itself equal to one? So shouldn't 0/0 = 1? No, because you can't divide by zero. The proper way for a computer to respond to an attempt to divide by zero is, "I have absolutely no idea what's going on here. I speak math, and you just asked me to do something that is outside of the language of math. I am going to either crash so I don't do anything stupid, return a reserved value that explicitly indicates that the answer does not exist, or jump out a level, throwing a runtime exception (as appropriate for the given language), and let YOU tell me what to do now. It has to be this way because there is never a single answer that always holds true about what a computer should do when encountering this.
This should be hammered into you first in precalc, and again in any first-semester intro to computer science course, and again in discrete structures, and again in a computer hardware course. This is the reason for a lot of the hostility for asking this question.
Maybe my memory is being selective, but I don't recall Law & Order ever doing something that egregious. Court Drama has overall improved quite a bit (partly thanks to lessons learned from My Cousin Vinny. That's more of a Matlock type sin.
Raising 40m is fine and all, but something tells me I'm not gonna be able to purchase a spool of this stuff in 2016 like the article boasts. That's just something you say to get media coverage and further investors.

This conference is gonna be off the chain! Unchained, as it were.

So do it 3 times and merge the results. Boom: 4-Nines accuracy. Right?

Windows Powershell really isn't too shabby if you look at it objectively.

Or wait, how about "Not a Number" because that is the only way to resolve jump-discontinuity.
The Limit as x aproaches 0+ of a/x = infinity.
But the Limit as x approaches 0- of a/x = negative infinity.
because this represents a jump-discontinuity, the value of a/0 is just plain undefined.
This is like week-1 of high school precalc shit. Come on.
Does anyone want their div by zero errors to result in anything other than zero?
Yes.
No.
