You add steps to your debate that aren't in debate. Everyone accepts that there is climate change, and everyone accepts that it is due to natural causes (e.g. ice ages).

This is both sophistry and demonstrably untrue. Some people deny that the Earth is more than 6000 years old, so they don't even believe in the ice ages. This isn't just a bunch of isolated cranks, either. Young Earth creationism is popular among Evangelical Christians, including ones who have been elected to important positions in the US government.

More importantly, saying that everyone accepts climate has occurred naturally in the past is a distraction rather than an answer to scientists who are saying that humans are changing the climate right now. There is massive amounts of evidence showing that the climate has changed significantly in the recent past, that there are no known natural factors that could have caused that size of climate change, and that there is an obvious, human-created environmental factor that can account for the observed climate change. Bringing up the ice ages is classic climate denialism.

Comment Re:Sony playing catchup with Microsoft (Score 2) 277

How on earth do you figure this is a "blow" in the console war? Are you suggest that Microsoft was somehow behind this? Or is everything that gets reported on and is related to Playstation\Xbox now some sort of insidious plot to discredit one or the other console?

In reality it sounds like pure incompetence at Sony (and the same in the story you link about Microsoft) and I think when many people are affected by this sort of thing it's fair enough that it's covered on tech sites. It doesn't have to be part of some 'console war' that you parenthesize with apparent disdain while at the same time perpetuating the idea.

We'll have more information about the gravity attributes and locations of dark matter,

Both of these experiments aim to detect collisions of dark matter particles with their respective detectors, and if found give an estimate of the particles energy. Neither are astronomical surveys that would tell us anything about the gravitational properties or distribution of dark matter.

Some people are still screaming that it isn't happening.
Some have said OK, but humans aren't doing it!

And a lot of the people saying those things are the same people. They go through the same series of denials:

  1. The climate isn't changing.
  2. The climate is changing but it's natural.
  3. Humans are causing climate change, but it's no big deal
  4. It's a big deal, but the suggested changes to deal with it are acceptable.

The worst part is that they'll concede points through the list of denials in one argument, and then turn around and go back to the top the next time they argue the point. Going through the series of denying arguments and reverting after the end of every argument is the key sign you're dealing with somebody who isn't arguing the issue in good faith.

Comment Re:Colour temperature vs CRI (Score 1) 278

I would think you'd want a high CRI non-incandescent for color critical work. Yes, incandescent lights have a theoretically perfect CRI, but their color temperature is so low that the light they put out is very blue deficient. Many people apparently like that light and praise it for its warmth, but it's so lacking in blue that it distorts color perception at least as badly as a low CRI would. I'd rather deal with the small imperfections in the light from a 90+ CRI fluorescent or LED with a color temperature of 4000K or 5000K than the lack of blue from a 100 CRI incandescent.

You could always shop specifically for fans that have the kind of socket you want. Despite what you say, there are actually plenty of ceiling fans out there that still use medium base bulbs. You can even buy a fan and the light set separately, so you can get exactly the lights you want. But don't let that get in the way of a rant.

I would even argue that as long as the students who did most of the work have their name listed as first author, there is nothing wrong with this arrangement. I dropped out of my master's program after the first semester because I was being pushed to publish, but wasn't being plugged into any research existing programs. Every "unique" idea that I thought of turned out to have already been studied exhaustively back in the 70's or earlier. All the favorite students in the grad program were people who ignored this inconvientent fact and managed to get rehashed bullshit accepted into conferences.

Several years later I went back to school at a large state U that plugged me into the work they were doing, showed me what the state of the art was and where there were gaps that hadn't been researched in detail. Without building off the ideas of my advisor I would have never been able to do meaningfull research that progressed the state of the art, and would have had nothing worth publishing. He deserved to have his name on my papers.

Everything is a continuum.

That is an exaggeration. Things grow as a continuum, but they can get separated when the parts in the middle die off. You wind up with a branched structure because things really can get far enough separated that when the middle dies off they can't reconnect. For example, mammals really are distinct from other tetrapods because the forms that connected them died off and they've been developing in different directions ever since.

Comment Re:2-year CFLs (Score 1) 278

I wonder how much of that is because of the way you're using them. They give a lifespan estimate, but that's making some very broad assumptions about how you use them. Those estimates about how many years they'll last are based on you using it for so many hours per day but only turning it on a few times per day. If you turn the light on and off many times per day, as you might in a bathroom or if you're using an occupancy sensor, the filaments will wear out a lot sooner than the projected lifespan. If you're really turning the lights on and off a lot, LEDs are probably a better choice.

Their energy savings is not that much better than CFLs...

That depends on what you consider "much better". The newer LED bulbs at big box retailers like Home Depot are now using around 1/3 less power than equivalent CFLs. That's not the same kind of savings you get from switching from incandescent to CFL, but it's still substantial. If power costs more than about $0.10/kW, they're probably worth the increased up-front cost.
