Have I been messing with my brain?

Why some people can sleep through anything
[Via Eureka! Science News]

Ever wonder why some people can sleep through just about anything, while others get startled awake at each and every bump in the night? A new report in the August 10th issue of Current Biology, a Cell Press publication, offers some insight: sound sleepers show a distinct pattern of spontaneous brain rhythms. “We found that by measuring brain waves during sleep, we could learn a lot about how well a person’s brain can block the negative effects of sounds; the more sleep spindles your brain produces, the more likely you’ll stay asleep, even when confronted with noise,” said Jeffrey Ellenbogen of Harvard Medical School.

Noises of any kind have always waked me up. When traveling, my father’s snoring would wake me. I’d try and sleep under the sink or in the bathroom to get away from the noise. College was hell, with all sorts of noise ongoing at all times at night.

It was not until I discovered the ability of white noise generators to cover noise up that my sleep habits stabilized and I got through the night most nights without being awakened.

But I wonder if the white noise generators I have been using cause an alteration of the thalamus, since it is getting noise all the time now. I wonder how I have reshaped my brain over the last 30 years? Or my son, who has had such generators his whole live, although he has shown a splendid ability to sleep without needing them?

Frankly, I’d rather get a good night’s sleep than have a normal brain, if it really comes down to it.

Conservapedia is so much fun to read

Heliocentrism is an Atheist Plot
[Via Balloon Juice]

I had no idea that the Theory of Relativity was a liberal scheme, but thank goodness conservapedia is on it:

There is so much there to love I just don’t know where to start, whether it be the conflation of relativism and the theory of relativity, or the action-at-a-distance by Jesus (WTF?). The footnotes are just as awesome:

See, e.g., historian Paul Johnson’s book about the 20th century, and the article written by liberal law professor Laurence Tribe as allegedly assisted by Barack Obama. Virtually no one who is taught and believes relativity continues to read the Bible, a book that outsells New York Times bestsellers by a hundred-fold.

This has to be a spoof, right?

BTW- longtime readers will understand the title of this post.

It has been a while since I have discussed the treasure trove that is Conservapedia. I love how it is all the fault of liberals.

And the talk pages are really worth reading to get an idea of what happens when people argue some of these points. How about this exchange regarding the fact that many of the intuitive ideas we have about forces do not hold under relativity:

I don’t think that’s the source of our confusion. I think the main problem is that, according to Newtonian mechanics and thus according to our mechanical intuition, orthogonal things tend to operate independently. Not only that, but a force exerted on an object is usually independent of the object’s momentum. In relativity, none of these things are true, due to the fact that velocities no longer add like vectors (and thus acceleration no longer incurs a cumulative change in velocity in the usual way.) This is seen as some sort of logical flaw or paradox simply because it contradicts the deeply ingrained intuition that came from the previous theory.–NgSmith Sun Dec 13 18:10:46 EST 2009

Theories that don’t produce anything useful are often a waste of time, or simply false. I realize that liberals tend to downplay accountability — a conservative insight, but theories should be accountable by what value they yield, particularly when taxpayer dollars are spent (wasted) on the theory.–Andy Schlafly 16:55, 7 January 2010 (EST)

I call gps a pretty darned useful invention but it doesn’t work if you don’t take into account relativistic effects. I think that not knowing where relativity is used speaks volumes as to how close minded those trying to disprove relativity, which is different from relativism. (a point completely overlooked by the page) Gaurdro 12:31, 24 May 2010 (EDT)

Andy Schlafly’s response it telling. In fact, he keeps stating that since GPS is corrected by engineers that do not need to understand relativity to make the correction, that relativity is really not useful. Or that nothing useful has ever been built using relativity, even as he is shown the use of synchrotron radiation in medicine.

That, more than anything, seems to be the goal of Conservapedia. Sure, perhaps an engineer does not need to understand relativity to correct a GPS satellite. But someone did want to understand why the discrepancy existed.

Schlafly seems to flat out not care if we understand why something works, why understanding relativity increases our understanding of the world around us. Doing something without understanding sure seems fine with him.

If liberals tend to downplay accountability, then I must add that conservatives, with Andy Schlafly as an example, tend to downplay understanding.

The value of the Theories of Special and General Relativity is immense, as the comment about GPS demonstrates. No other competing theory explains as many of the facts of the world around us, or is as predictive.

Einstein knew nothing about GPS satellites yet knowledge of his theories of special and general relativity is needed to understand why they work properly.

I would be willing to bet that if we followed the physics of the Bible, as evidenced by the action at a distance by Jesus, we would not understand the time discrepancies of GPS, how synchrotron radiation could be used for medicine nor many things we have come to value.

As with most of these types of discussions from denialists, there is no attempt to construct a different model to explain the data we have. There are only attempts to drag down a model because it is religiously inconvenient.

The predictive qualities of a scientific model – the ability to explain and understand things found after the theory is formulated – are some of the important aspects of what makes the theory useful for our understanding of the world around us. What does Andy Schlafly propose to replace this model with?



Now these numbers for Macs are more believeable

Regarding Mac Market Share Among College Students
[Via Daring Fireball]

Philip Elmer-DeWitt, quoting survey results from Student Monitor:

Among those who planned to purchase a new computer, 87% planned to buy a laptop. And among those students 47% planned to buy a Mac.

Among student laptop owners, Apple has the highest share, at 27 percent. These numbers are short of the claim by analyst Trip Chowdhry that “70% of incoming University freshman students are coming with Macs”, but they’re still remarkable, and the trend is very strong in Apple’s favor.

I wrote somewhat quizzically about another analyst’s numbers saying that 70% of students would be buying Macs. This is a little more believeable and bodes well for Mac sales.

The difference between trying to hold onto your customers and adding new ones

Microsoft’s New ‘PC vs. Mac’ Site
[Via Daring Fireball]

Matt Gemmell nails it:

Apple and Microsoft have something in common: their “Mac vs PC” comparisons both target PC users.

Offense vs. defense.

[More]

Partly why everyone talked about the Apple Mac-PC ads and few will be talking about this new Microsoft Mac-PC ads, just as few talked about their previous ones.

I guess the commenter was right about Papermaster

Papermaster’s Apple exit a result of falling out with Steve Jobs
[Via AppleInsider]

Mark Papermaster’s departure from Apple is said to be a result of “cultural incompatibility” and losing the trust of Chief Executive Steve Jobs, and not solely a result of the iPhone 4 “antennagate.”

[More]

I quoted a comment about this the other day. The comment was, “I’d wager that he and Steve Jobs got into it about the antenna with the final word being “See, Steve? I told you so.” — to which, there could only be one reply: “Have a nice life, Mark.”

Sounds closer to the truth than what a lot of the media was speculating about.

Apple uses miracle materials

Apple obtains exclusive rights to custom, super-durable metal alloy
[Via AppleInsider]

Apple has entered into an exclusive agreement to utilize amorphous metal alloys with unique atomic structures, allowing products that are stronger, lighter, and resistant to wear and corrosion, AppleInsider has learned.

[More]

So, Apple has an exclusive license for the use of this high tech metal product. Coupled with its use of Gorilla Glass from Corning – Corning is investing $180 million to expand their production of this material which has set on the shelf for 40 years until a single company asked to use it.

Apple found a use for Gorilla Glass and now others are using it also. But apple has an exclusive license for this material so it will be harder for other companies to use it to copy Apple designs.

Apple does not innovate just with computers. It has been a materials science innovator for quite some time. I am excited to see what it will produce with this novel material
