    That's a good question. At first glance, per-captita consumption seems like the thing to focus on. Honestly, it's probably a good place to star; however, as that gap closes things get more subtle.

    Consider 4 people, entitled to equal carbon emissions. They form 2 couples and the first decides to have 2 kids, while the second decides to have 6. Are the resulting families entitled to equal emissions, or is each person still entitled to equal emissions?
    - It's unfair that children born into a large family should have less then those born into a small family
    - It's also unfair that the actions of a couple choosing to have a large family should slice the environmental pie more thinly, reducing the share of those who chose to have a small family. Furthermore, the first option leads to the question of what's a fair baseline and basic human rights, while the second leads to a tragedy of the commons or lowest-common-denominator scenario.

    I know plenty of people who don't get very much activity, eat things loaded in sugar and fat, yet are incredibly skinny and healthy looking. I know other people who exercise a ton, eat extremely healthy food choices, yet are very, very large. There are some reasons for obesity that go way beyond just what you eat....

    Fair enough - but you seem to be making a classic mistake. It's not so much what you eat, but how much of it, that determines your weight. Now, as someone who has to work to control his weight - yes, I envy my fiance, who can eat whatever he wants. But the difference isn't that he can magically eat way more than I can - it's that his appetite is more easily sated. Sure there are also metabolism differences, but in reality a very obese person is almost certain to be burning more calories than a thin person at a similar level of physical activity, because all that fat takes energy just to keep alive, and more still to move around.

    Where I'm going with this is: sure, life isn't fair. It's more difficult to control eating for some than for others - but at the end of the day what you eat is a conscious choice. Helping teach, encourage, and in some cases force (depending on age, we "force" young kids to do everything) people to eat in a way that will lead to a healthier life can be justified.

    48 heads and 52 tails!

    Seems pretty reasonable. The question is, now, how likely is it that I flipped exactly 48 heads and 52 tails?

    If you know something about a binomial random variable (which is what we just sampled from), you know that this is (100 choose 48)*.5^(100) = .0735!

    Wow...and that was with only 100 random coin flips. A 1 in 20 chance that, by their metrics, this was a fair set of coin flips (see where the logical incongruity happens?)

    You've used quite the wrong metric, asking "what are the odds of this EXACT outcome in a fair contest". The right question is "what are the odds of at least this this much deviation from the expected outcome in a fair contest". In the case of your coin toss your questions would be "how likely is it that in 100 flips, I will get 52 OR MORE of either heads or tails" (note that if you were asking only about tails, you'd just get 1/2 the number, but considering the odds of 50 or more tails is only 50/50% it's a bit misleading that way).

    To get this you would sum all probabilities in the range, eg
    (100 choose 0)*.5^(100) + (100 choose 1)*.5^(100) + .... + (100 choose 47)*.5^(100) + (100 choose 48)*.5^(100) + (100 choose 52)*.5^(100) + (100 choose 53)*.5^(100)+... + (100 choose 100)*.5^(100)
    which is about 76.4%.

    That is, about 3/4 tosses of 100 coins will differ from 50-50 by at least two flips, this is very similar to the probabilities for these events in the recent US election, held up in the article as an example of 'normal' results.

    Now if you'd gotten something like 38-62 you'd have results about as unlikely as this election (2%).

    If you're familiar with stats at all, in general it's when the odds fall below 5% that you have an interesting result, 2% is quite interesting (though it depends on how often the event happens - 2% in an election that happens once/4 years or so is going to happen by chance with a mean period of 200 years).

It has it's up side - you sometimes get taught by research profs who are amazing at why they do, on the cutting edge, and have amazing enthusiasm to impart. On the other hand, you also get research profs who begrudge every minute of actually teaching - student complaints fall on def ears (even more than normal) because "he's a research prof" (who may pull in millions worth of grants).

    Definitely on side here. I agree with all of your points but think you missed just two

    In engineering you think not only about getting something to work, but (usually) how to keep it working. That same pragmatism that says "it needs to work" also says "the developers will make mistakes" - which means you need to study how to avoid mistakes, how to catch mistakes, and how to deal with mistakes. There's definitely a science component, but again the human component is also critical.

    The other major component is that a Software Engineer, like any other Engineer, needs enough fundamental understanding of all other branches of Engineering to work with his counterparts. A Computer Scientist may not need to know anything about Physics, Chemistry, Electronics, Politics, or the environment, but a Software Engineer needs a little of each, so that he can work with his counterparts in those fields.
