Comment Not just smartwatches (Score 1) 81

Nobody except Asia buys watches anymore.

Watches, smartwatches, health monitors - if you're not actively sick, they tend to be a bad idea.

Research studies have shown smartwatches actually encourage you to self-defeat health and exercise goals, by setting an upper limit on how much you do. Better methods include bar measures (where you start off in Red, go to Yellow, go to Green, and then go Yellow if you exercise too long without water or a rest break), candy systems (e.g. Pokemon Go where you get candy for your monsters if you complete a designated unit, but it doesn't stop adding), and other real feedback cycles.

Also, self-monitoring tends to decrease the reward aspect of the exercise itself.

Plus, seriously, who spends $500 on a fricking wristband?

no, peer reviewed scientific journals on ScienceDirect. Most alumni of research colleges and universities can access that, and a larger quantity of such research is available to the general public if it's federally funded in part. You can usually read the published articles, whereas research students staff and faculty can read the not yet published research.

Adapt. The future owes you nothing. Science has no agenda.

The energy of that storm was, from our own calculations, about 50/50 normal cyclical energy and human added climate change energy.

Future storms will be even higher levels of human created energy.

Heat doesn't just disappear. Although some ME and CE colleagues here at the UW have a cool example of transforming low grade heat into electricity to charge your cell phones in Africa and disaster zones (and also for hiking) check out their kickstarter

Comment Re:Problem is effects now are from 20 years ago (Score 1) 209

No, that's like thinking that your full tank of gas is immediately burnt after you fill it. The effects of the mass of your gas are added to vehicle weight over the duration of the gas tank being used. You start off with a full mass and it gets used up over the lifespan of the tank of gas, at the end of which it's a mostly empty (theoretical) tank of gas (actually, tanks are designed with a 10 percent reserve, so it goes from 110 percent to 10 percent).

The C02 you release does go in the atmosphere immediately, but the effect is over a 100 year period (as was proved more than 100 years ago). N02 has a 10-20 year lifespan. Methane is also a short duration gas, like N02, but both have other side effects. Think of it as a slowly deflating bubble of C02 - at the end of 100 years it's empty, but 50 years on it's only half empty. All the C02 in the atmosphere is from the last 100 years. We add a small fraction today (say 2016), but the prior 100 years is all there, on average. Thus we get the effects of the Arctic melting permafrost impacting us now, and for the time it takes to cycle it out.

it's like adding more and more blankets as you get hot. stop putting on more blankets. the blankets are slowly removed, but you'll still get hotter, since you have too many blankets on.

If you are having font size problems due to readability, in general, a site-wide font size increase is recommended. If a specific article chose very small fonts, most sites have A symbols with a +/- font size increase/decrease that applies to the page.

Or you can increase font sizes in general on Chrome and Opera and Firefox.

Now go Read The Fine Manual. I'm not here to solve your problems, grandpa.

Don't want to sound like an old fart, but I'm going to... the first web pages looked fairly similar to a printed page because the printed page is pretty much the ideal way to read.
Jesus, some of us have grandparents who died in the war over Serif/Sans-Serif fonts.

unfortunately, Comic Sans won the font wars, in a lightning strike that was unforeseen by all
