  1. First...what exactly does the "Department of Energy" do for us in the US?

    They design and build nuclear weapons, and maintain the nuclear stockpile, for one.

    Yep. Ditching the steering wheel and the pedals would be really, really dumb. It would mean that if the car had a problem it would be stuck where it is.

    Steering wheels are useful.

  4. Uh, this is the most uninteresting news ever. So, you're saying that Apple has put a lot of its spare cash into government bonds, which pay out the usual government bond interest; which are actually historically relatively low rates compared to other interest rates. This is interesting why, exactly?

  6. The Garbage Dumpster Argument [Re:Climate chan...] on Climate Change Will Stir 'Unimaginable' Refugee Crisis, Says Military (theguardian.com) · · Score: 3, Informative

    Ah, the garbage dumpster argument: pile enough garbage up, and tell the reader somewhere in the dumpster one argument might be real; you need to wade through all the garbage to find it.

    I don't have time to wade through all the garbage. I'll go with the three strikes you're out approach: if your first three arguments aren't convincing, I'll stop there.

    There are lots of reasons I am skeptical of this: 1. A primary method of convincing others is to ridicule and insult them. Notice the responses and downvotes this post will get.

    Not relevant.

    2. We have seen vastly higher CO2 levels in planetary history

    Yep. And, you know what? All of those higher CO2 levels were associated with higher global temperatures! That's not evidence against the effect of carbon dioxide on global warming-- it's evidence for the effect of carbon dioxide on global warming

    and right now we are seeing what is actually all time lows..

    Nope. Current levels are higher than it's ever been for as long as we can measure the CO2 record from ice cores, well over a million years. I think you're talking about really long ago. In that you'd be correct: carbon dioxide levels were higher before the Pleistocene. These were also, however, times when the Earth didn't have an ice cap or glaciers. So, again: this isn't evidence against the effect of carbon dioxide on climate-- it's evidence for it.

    We should expect CO2 increases and, in fact, hope for them as going much below 300 ppm would see the beginning of a massive plant die off - there's a reason commercial greenhouses pump CO2 into their facilities.

    Slightly misleading. Carbon dioxide increases plant growth-- but only in environments in which CO2 is the limiting resource, not other nutrients, water, or sunlight. In a greenhouse, where you make sure that the temperature, nutrients, and water are all optimal, sure, it's worth adding CO2. Outside, though, it's only one effect among many.

    3. The temperature change we are seeing now is far from unusual, we've seen similar changes in both rate and magnitude before. In fact, what we are seeing now does not stand out from background noise.

    Doesn't stand out from the background... over tens of millions of years. Even so, actually, the current rate of warming is pretty exceptional. It does, however, stand out from the background over the period in which we have good measurements of both temperature and of all the other forcing factors, such a solar irradiance. So: no.

    The greenhouse effect, of course, has been known for well over a century, but the modern global climate model incorporating numerical integration was Manabe and Wetherald, 1967. But, of course, since you dismiss all climate scientists, you dismiss that, I suppose, along with all the other work ever done. In fact, you can dismiss every paper! They're all done by " 'only a small subset of "climate scientists'". Thousands of them! Decades of Journal of Geophysical Research- Atmospheres: every single paper written by that 'small subset.' That "small subset" is so incredibly prolific-- they're simply amazing, that small subset; not only have they written every single paper on climate science for almost fifty years, they've taken over the whole of atmospheric science in America, Britain, France, Germany, Italy, Japan, and Australia.

I love the hero scientist stories, too, but the final, and the most important part of science is that you have to explain your results to other scientists, and get them to understand it and understand and credit the evidence.

    Wrong.

    The only thing that matters is being able to reproduce the proof independently. If the results proving a theory are unable to be duplicated independently it's nothing more than an unproven hypothesis.

    Exactly. That is how you get scientific consensus, when other scientists can duplicate your reasoning and follow your results, and compare your results to results from others (often, from others in different fields).

    Science is not a one person endeavor . Science is, in essence, a series of protocols to ensure that you are observing the world, and not fooling yourself, and an essential part of this is that you have to get other people's eyes looking at what you do. If you cannot explain it to other scientists and have them look at your data and agree that you're seeing what you say you're seeing: it's not science.

    Just because they claim to not be on the network doesn't mean that they "can't possibly be hacked"!!

    First, it turns out that some machines that the vendors say aren't on the network have, in the past, ooops turned out they actually did have undocumented wifi ports.

    Second, machines have to be accessed to put the candidates into the machine. This requires access, and any time there's access, they can be hacked.

    Third, the machines have to be accessed to get results out of the machine. This is another point at which that the results could be tampered with. Doesn't matter if the machine is reporting 1000 votes for Candidate X and 200 votes for candidate Y if the man in the middle alters that to 500 and 700 as it's transmitted.

    I'm baffled. What do you believe blockchain technology would do for voting? How would it make the system better?

    The whole point of voting is that you need to make the votes anonymous: a particular vote can't be traced to a particular voter. Blockchain could give you a verified receipt for your vote... but what is the usefulness of that?

    It seems to me to be a technology with no evident usefulness to the application.
