Hi alls,Now you’re on your merry way perusing through the lands battling monsters, rescuing damsels, and most importantly leveling up, and that’s all good. But then you realize, you’re really slow! Certainly, people have told you the entirety of Caltech fantasy-scape could be traversed in 7mins, and it’s probably true if by 7 they meant 15mins. Which is mildy worse but wouldn’t be a problem if only the Magic trainer and Swordwork trainer didn’t have their lessons back to back on opposite sides of the map. (Braun gym is on the South West side of campus while Annenberg building is on the North East.) So you decide it’s a worthy investment to get a horse (bicycle). Unfortunately, there are thieves prowling about, exiles from other worlds, waiting to get the chance to steal your horse. So it’s a natural idea to get safety in the form of a U-lock. This U-lock is about the size of a door and goes around your horse to keep it safely secured in a stable (bike rack). But sadly, the thieves are wily and have developed a method of splicing animals together. They no longer need your entire horse and are simply content to steal it’s back legs which are then kept in storage until next needed. Just a warning that although the honorcode makes sure no Caltech member will take unfair advantage of another, people from off campus do frequently steal bikes, occasionally taking them apart and stealing just wheels. Curiously, the back wheel of my bike, and the front wheel of someone else with a very similar looking bike were stolen. Mystery Nut X now has a full set of wheels…So careful where you park.
Anyway, a while back, an email was sent out to the dabney house spam list with subject line “Is that a joke about the size of my brain”. The body goes as follows:
“I wondered recently: how much memory (in bits or whatever) can a human brain
store? After some ooming around I figured on 10^11 neurons devoted to
memory. This gives us a lower bound of 10^11 bits (10GB) and an upper
bound of (10^11)! (way too huge). I was hoping to narrow this down a
bit, but I lack the understanding of neuroscience/CNS to know how
neurons store data other than some rough idea that it has to do with
pathways.Failing biologists, we turn to mathematicians. A better
approximation involves assuming that for N neurons each one can only
form connections to any two of its neighboring m neurons (m = 10) and
can form paths of arbitrary length. Throw in a factor of 2 if you want
directed paths. This however involves more math that my tired brain can handle right now, maybe one of you can try that out?-pers”thinks with his thinking apparatus”on “Naturally the best thing to do is to give a well justified, scientifically derived, answer.Aka, let’s see what anime says.
Firstly to simplify the question, let’s restrict to people with eidetic memories, meaning more commonly, perfect recall. I’m assuming that a person with perfect recall has more memory than a person without.
From “To Aru Majutsu no Index” aka “A Certain Magical Index”
The main heroine with perfect recall has 103,000 grimoires loaded in her head from the English Purist Church. Consequently, she needs to wipe her memory every year or she will exeed her memory capacity and die.
Assuming further that a typical magical text is the size of the bible 7.7 Mb–>6.46e7 bits.Multiplied by the number of grimoires, 103000 * 6.46e7 bits –>6.65e12 bits.
Now assuming perfect recall memory renders life at 1080p, Given the movie “A Clockwork Orange”, 137minutes, 7G, 1 year –> 26873.258037G–> 2.3e14 bitsIn total, this means in total, she can store 2.4e14 bits in her brain.Impressively, not less than the lower bound (number of neurons in the brain 1e11) and not more than the bekenstein bound. https://en.wikipedia.org/wiki/Bekenstein_bound ( 2.6e42 bits)
Unfortunately, the English Purist Church also says, 10^14 bits is 15% of a brain while
10^12 is 85%
It seems the other characters in the anime also end up realizing the flaw
Depending on the house and style of room that you choose, rooms can look pretty different at Caltech. Generally, the south houses (Blacker, Dabney, Fleming, Ricketts) have similar options, and the north houses (Lloyd, Page, Venerable) are similar in their room styles as well. Rooms in Bechtel and Avery tend to look different from the north and south house rooms as well. In this blog post, I’ll be sharing an example of what a Fleming (south house) single generally looks like, and how I’ve chosen to decorate mine.
Now, based on the title you may be wondering what kind of story this will be. As you will soon find out, it’s a story of adventure born out of the pure, dark chaos that fills the minds of sleep deprived Caltech undergrads.
I’m starting a new miniseries on the blog – Film Club! Each episode, I’ll share a short clip from a popular piece of media, and then completely dissect and overanalyze it, because let’s face it, I’m doing it in my head already anyway. You say “buzzkill.” I say “science.” We’ll kick things off with a clip from Gravity Falls I discussed a bit in my previous post: Season 2 Episode 12, A Tale of Two Stans. If somehow you haven’t watched this show yet (?!)… spoilers incoming!
