Comment Re:Consider the author (Score 1) 729

What a stupid thing to say! When one says "consider the author," what he should mean is, "His ideology may have stood in the way of good science (e.g., scientists trying to accommodate their own religion)." This is a valid suggestion, and worthy of investigation. In this case, it seems it is your own ideology which prevents you from contributing anything of value.

Comment A poverty-ridden and overpopulated society... (Score 0) 729

Yes. The "religiosity gene" -- this is a dishonest way of saying "indoctrination of children into their parents' religion," by the way -- will dominate a poverty-ridden and overpopulated society because this irresponsible practice takes no account for the fact that resources are limited. Given three or four generations of exponential growth, what's any person with half a brain to expect? It's outright despicable, in my opinion.

It's entirely possible that the English teacher raised a fuss to the administrators, who caved in like the spineless cowards they are. This is another example of the careerism I talked about, but in a different context. As for the ex lab tech, if she had an accurate understanding of biology to the level being taught, why shouldn't she teach it? Were there better candidates?

An English major with an accurate understanding of the sciences should certainly be allowed to teach to the level of his comprehension, though a science graduate should obviously be preferred. The real reason teachers fail their students is because most of them, 90% or more in my own district, would sooner cheat them out of a proper education than risk their careers to even a minimum extent. They concern themselves only with how they look to their overpaid administrators so that they, themselves, will one day be overpaid administrators. And so on, and on, and on...

Comment Focus on useful tasks (Score 1) 467

Nobody gives a crap about how to navigate the terminal or GUI. These concepts are too abstract to be useful, and too boring to care. People learn by making connections to things that are important to them. You're talking about a group of CS students, so what will a CS student most likely want to do? Off the top of my head: online research and collaboration, writing technical papers, authoring and compiling code... What do these tasks involve? You're the teacher. :)

Hey fishbowl. Are you truly suggesting that a company has no obligation to treat its workers fairly, merely because the chips are in the bosses' favor? That if you're not in a position to be treated fairly, then you don't deserve to be? What a disgraceful thing to say!

Comment Re:Keep up or shut up (Score 1) 785

Hey shutdown. All of that may very well be true, and I'm not saying anything to the contrary. My point is that the decision was both irrational and unfair. It's fine to be competent and knowledgeable, but it's better to be experienced and loyal to the company. I think it only fair for a company to give a certain amount of priority to the people who have already contributed so much to its success.

New Sunlight Reactor Produces Fuel 269

eldavojohn writes "A new reactor developed by CalTech shows promise for producing renewable fuel from sunlight. The reactor hinges on a metal oxide named Ceria that has very interesting properties at very high temperatures. It exhales oxygen at very high temperatures and inhales oxygen at very low temperatures. From the article, 'Specifically, the inhaled oxygen is stripped off of carbon dioxide (CO2) and/or water (H2O) gas molecules that are pumped into the reactor, producing carbon monoxide (CO) and/or hydrogen gas (H2). H2 can be used to fuel hydrogen fuel cells; CO, combined with H2, can be used to create synthetic gas, or "syngas," which is the precursor to liquid hydrocarbon fuels. Adding other catalysts to the gas mixture, meanwhile, produces methane. And once the ceria is oxygenated to full capacity, it can be heated back up again, and the cycle can begin anew.' The only other piece of the puzzle is a large sunlight concentrator to raise the temperature to the necessary 3,000 degrees Fahrenheit. The team is working on modifying and refining the reactor to require a lower temperature to achieve the two-step thermochemical cycle. Another issue is the heat loss which the team claims could be reduced to improve efficiency to 15% or higher. Since CO2 is an input, the possibility exists for coal and power plants to collect CO2 emissions to be used in this process which would effectively allow us to "use the carbon twice." Another idea listed is that a "zero CO2 emissions" is developed along these lines: 'H2O and CO2 would be converted to methane, would fuel electricity-producing power plants that generate more CO2 and H2O, to keep the process going.' The team's work was published last month in Science."
