Comment Re:Agrument in favor of modularity (Score 1) 82

I don't have to do anything. Even stored under ideal circumstances li-ion batteries lose capacity.

What matter is capacity relative to demand. In a phone like the Droid Maxx from a few years ago with plenty of surplus battery the phone will still be usable four years later. But something like a Samsung Galaxy S6 barely has enough battery to make it through the day when brand new and is pretty much unusable two years later even under ideal conditions.

Comment Re:There's a lot more iron much closer... (Score 2) 173

And there's some twenty million tons of gold dissolved in the Earth's oceans. Jules Verne made it the source of Captain Nemo's incredible wealth.

To put twenty million tons of gold in perspective, all the gold that has ever been mined by humans totals up to about 180 thousand tons. To put in another perspective: sure, it's gold, but at a concentration of thirteen billionths of a gram per liter of seawater it's worthless unless you have unlimited time and energy to extract it.

That's the problem with asteroid mining in general. Until the cost of changing an object's momentum goes down drastically it's not worth doing. If Pysche were a 1000 kg block of pure, refined platinum (market price: $34 million) you'd be hard-pressed to retrieve it and return it to Earth at a profit. Which is not to say asteroid mining is a bad idea; but first things first: you've got to reduce the price of interplanetary propulsion by a couple orders of magnitudes. One thing that never happens in a sci-fi asteroid mining scenario is the hero worrying about running out of gas. Propulsion in stories is always practically limitless and free of charge. Real propulsion will never be that good, but it could get good enough.

How much thickness do you think the extra outer layer of plastic adds to the phone? If it has to be more than a millimeter I would be surprised.

Personally, I think it has more to do with the fact the lithium ion batteries have a finite shelf-life than it does with thickness. That means in two years you need a new phone even if you never added any software to it and managed the battery recharging perfectly. Even if the phone had been sitting in a box all that time it'd have significantly less battery life.

The patterns were a mishmash of unrelated structures that were as misleading as they were illuminating.

This pretty much describes the state of every branch of science after a major influx of new data. Just look at the maps of the world produced after Europe became aware of North America. Early maps sometimes show California as an island; and it's not because the cartographer is stupid; he just put the data at his disposal together into what was at the time a plausible conjecture. And in fact the problem might not even have been that he was ignorant. He may have misinterpreted some of the (at that stage) imprecise data he had to work with.

New information confounds. The detection and resolution of conflicts in data is arguably what science is.

Comment Re:New flash - Bugattis owned by rich not poor (Score 3, Interesting) 304

Except some poor and middle class kids get into Harvard -- in fact they get their expenses paid. That's not the case for Bugattis.

And it's for a good (or at least shrewd) reason: Letting the intellectual elite into your exclusive school lends the prestige of their academic accomplishments to the financial elite who attend.

Look at our president-elect, who likes to point to his attendance at Penn as proof that he has a very good brain. Well, I'm not one of those people who think he's actually stupid but he got into Penn because he was rich and had family connections in the admissions office. He's not in the same league as the kids who get into Penn on a scholarship.

My brain decides to store things I don't care about and refuses to store things I specifically study.

From your perspective that's a bug. From your brain's perspective it's a feature. Your agenda is getting a good mark in your course. Your brain's agenda is to survive, reproduce, and generally have a good time while doing so.

The thing that you think of as "you" is just a tiny film of consciousness on top of an ocean of unconscious activity. You think "you" live in the present, but actually it takes over 300 milliseconds for your consciousness to become aware of anything, and by then, most of the time, your brain has decided what to do about it. "You" mainly come up with rationalizations for decisions your brain has already made. Which is not to say that consciousness isn't important; it isn't quite as sovereign as it believe itself to be.
