Internet Use Affects Memory

I had an interesting discussion with a professor about two years ago regarding our living in the information age. I don't even remember how it came up, but I postulated that rote memorization of facts is falling by the wayside as a result of the easy access of information at our fingertips. Why do I need to memorize my Greek lute tunings? If I ever need to know them, I'll be able to look them up on the fly. They're not something I need to know on a regular basis, but if I do, I have Google, encyclopedias (both wiki, and paid), online scholarly journals, old textbooks (looking at you, Grout), etc, etc. The information is stored in a very accessible manner, and gone are the days when needing to know something minute meant six hours in a library digging through books hoping against hope you'll find the answer you need. Information has truly become populist in accessibility.

Furthermore, anything you do need to recall quickly and on a regular basis, you will be able to because of repetition. If you use the information on a regular basis, you'll retain it. That's how our minds work. If not, you know where to find it. We won't become a society of inane robots who don't recall anything, rather we'll simply use our minds more efficiently, retaining that which is vital, which access to those facts that are less so.

And while clearly alien to this professor's experience, I could tell he didn't entirely disagree. Not sure he totally agreed with my viewpoint, but there was clearly some honest consideration of truth in my prediction.

Well, while I was blowing hot air about it, apparently scientists were actually researching it.

Abstract from study:

The advent of the Internet, with sophisticated algorithmic search engines, has made accessing information as easy as lifting a finger. No longer do we have to make costly efforts to find the things we want. We can "Google" the old classmate, find articles online, or look up the actor who was on the tip of our tongue. The results of four studies suggest that when faced with difficult questions, people are primed to think about computers and that when people expect to have future access to information, they have lower rates of recall of the information itself and enhanced recall instead for where to access it. The Internet has become a primary form of external or transactive memory, where information is stored collectively outside ourselves.

And from the NY Times article where I first encountered this bit of info:

The scientists, led by  Betsy Sparrow, an assistant professor of psychology at Columbia, wondered whether  people were more likely to remember information that could be easily retrieved from a computer, just as students are more likely to recall facts they believe will be on a test.
Dr. Sparrow and her collaborators, Daniel M. Wegner of Harvard and Jenny Liu of the University of Wisconsin, Madison, staged four different memory experiments. In one, participants typed 40 bits of trivia — for example, “an ostrich’s eye is bigger than its brain” — into a computer. Half of the subjects believed the information would be saved in the computer; the other half believed the items they typed would be erased. 
The subjects were significantly more likely to remember information if they thought they would not be able to find it later. “Participants did not make the effort to remember when they thought they could later look up the trivia statement they had read,” the authors write. 
A second experiment was aimed at determining whether computer accessibility affects precisely what we remember. “If asked the question whether there are any countries with only one color in their flag, for example,” the researchers wrote, “do we think about flags — or immediately think to go online to find out?”
In this case, participants were asked to remember both the trivia statement itself and which of five computer folders it was saved in. The researchers were surprised to find that people seemed better able to recall the folder. 
“That kind of blew my mind,” Dr. Sparrow said in an interview. 

The argument being made is that teachers might now start focusing more on broad concepts and synthesis than facts in their teaching style. (Which I think is something they should be doing anyway, but no one asks me.) Whether or not this will affect educational philosophy, I imagine we won't know for another decade or two, given how slowly these gears tend to grind.

New MacDefender Defeats Apple Security Update

Because no, Macs aren't immune to viruses or malware, and as their market share grows, the threat is only going to increase.

Apple released a security update yesterday (May 31) designed to rid Macs of the menacing MacDefender malware that has plagued users for nearly a month. But mere hours after the update, cybercriminals released a new variant of the malware that easily defeated Apple's belated security efforts.

Source article.

If anything, I think the threat to Macs is greater. They don't exactly have a lot of experience dealing with software based threats. Some people are in for a rude awakening when they begin to finally understand their primary protection has been the Mac's relatively small market share. As the market share increases, the targets on their back side increase as well. It's simply the market at work.

The Antikythera Mechanism With A Twist

Doesn't have much to do with any of my recent posts except that it's really cool, and I like anything lego. Having almost no knowledge of engineering, I can't say I totally understand the math within the gears concept, but fascinating nonetheless.

An Artificial Sun on Earth

Article here.

I have to say, while the potential is exciting for cheap renewable energy and the possibility of controlled fusion, at the same time, I'm hesitant. I saw Spiderman 2. I know how this can end.

There are some experiments I am very wary of conducting on Earth. We only have one planet.... lets try not to destroy it, shall we?

The Politics of NASA

Let it be known that I have very mixed feelings on NASA. As with any government agency, they seem to have a lot of bloat and fat that needs cutting, they seem to be inefficient and ineffective, and seem to waste a lot of money. However, I ardently believe in their purpose - that of pushing the limits of human technology and resources and reaching out to the stars.

Thus when I saw this article, I was definitely disappointed, both in NASA and the Obama administration. (This isn't the first time I was disappointed with this administration, but that's another issue.)

That fact that this article and story, as far as I can tell, broke on The Times, a London based news source, also disheartened me. Is America so apathetic regarding space exploration that our media won't give the story the time of day?

Excerpt of the story below:

Nasa has begun to wind down construction of the rockets and spacecraft that were to have taken astronauts back to the Moon — effectively dismantling the US human spaceflight programme despite a congressional ban on its doing so.

Legislators have accused President Obama’s Administration of contriving to slip the termination of the Constellation programme through the back door to avoid a battle on Capitol Hill.

Constellation aimed to build upon what was arguably America’s greatest technological achievement, the first lunar landing of 1969, by launching new expeditions to the Moon and to Mars and worlds beyond. Mr Obama proposed in February that it should be scrapped because it was “over budget, behind schedule and lacking in innovation”, but he has met opposition in Congress, which has yet to approve his plan.The head of Nasa, Major-General Charlie Bolden — an Obama appointee — has now written to aerospace contractors telling them to cut back immediately on Constellation-related projects costing almost $1 billion (£690 million), to comply with regulations requiring them to budget for possible contract termination costs.

The move has been branded a “disingenuous legal manoeuvre” and referred to Nasa’s inspector-general for investigation. “It’s bordering on arrogance by the Administration to boldly and brazenly go forward with this approach. It shows a blatant disregard for Congress,” said the Republican Congressman Rob Bishop, of Utah, whose constituency stands to lose thousands of jobs. Two weeks ago the Senate passed legislation that compels Nasa to continue work on Constellation unless Congress directs otherwise. That legislation is due to be signed into law by Mr Obama this month while Congress continues its deliberations over his proposal to cancel the current space space progamme.



Since this administration has, thus far, been all about big budget vast changes to our governmental structure, I'm surprised he didn't try to start a moon colony, to be quite honest.

Sarcasm aside, it's starting to look more and more like Virgin Galactic and other private space enthusiasts might be our last, best chance to get off of this rock. Or maybe India will take up the mantle in the United State's place. I'm sure that's a legacy we can be proud of, winning the space race only to give up and peter out in deference to the rest of the world.

Seriously. We first landed on the moon 41 years ago. Why haven't we been back since? This marks one giant leap backward for mankind.
