Sunday in what seems to be a routine

First, what wasn't routine. Spent way too many hours looking for 100% cotton scrubs. I can find some, like Comfort Scrubs (but for the 3x/4x/5x sizes I need, they require an extra 2-3 weeks to make them), or at All Heart (but those are only denim, and they don't have the pant sizes in stock), or if I just want tops and can find a pattern we like (this is for me and Bette), Scrubs Gallery or Lydias Uniforms (but they don't have all cotton pants). Also, as a part of these sites, their shipping can be difficult (although Scrub Gallery has the best options offering free shipping for just $29 in orders).

But then I spent most of the day studying. Tomorrow's test is the first one on the neural system (CNS and PNS gross anatomy and function). I've rewritten the notes, and done a few other things. Tonight will be another review, after dinner.

And the more I read and learn about the brain, the more I realize that a true AI/Singularity (in SF) is a pipe dream (at least with our current technology). Why is the brain compared to a computer? Because the computer is the most complicated thing we have at the moment, not because of any real functional similarity. I can make analogies between them, but it isn't the same. Understand, the brain was once called a switchboard, steam engine, etc, because they were the most complex thing we had at the time. It's also my belief that any AI will really be an emergent/accidental property of some system (akin to Skynet) than an intentional construct of humans. To give an analogy, if you want to think of the brain as a computer and the neural pathways as the transistors in the CPU of a computer, well there are some comparisons. However, a better analogy would be to compare the neurons (of which there are billions) to registers in the CPU, or actually little coprocessors of their own. To say the brain is a massively paralleled system is to only scratch the surface. The level of the brain puts even our largest constructed parallel system (including the distributed networks) to shame.

Also, as a side note, you may have heard that we only use 10% of our brain. Seems kind of miniscule, right? Except that we can only use 10% of our brains because that is the amount of neurons compared to neuroglia (cells that do other things than process or transfer information). You can only use 10%. That's the whole processing power you have available.
