([Word of] or [ Insert foot into ]) and [mouth]

I frequently find advertisements for new and improved calculus textbooks in my mailbox, although when glancing through the inevitable trial copy they send me I invariably never seem to find any of the “new and improved calculus” they promise.  (Most of it still looks several hundred years old, in fact.)

Today’s advertisement caught my attention though.  The last page has several testimonials in praise of the text, and while most are fairly generic, this one from a reviewer at Furman University stood out among them:

Even though I have never seen this book until recently, my lectures appear to be coming right from this yet-unpublished text.  It’s uncanny.

Is this really a good way to pitch a new text?  Why not just say:

There’s absolutely nothing in here that you as a professor can learn from!    Your students, who already complain you “lecture straight out of the textbook” will now be validated!  Even better, although we might be using the same innovative ideas you yourself came up with independently years ago, since we’re the authors, we’re the ones getting the royalties!

Just sayin’.

Grammies + mathematics = bad idea

All the singularities,
All the singularities,
All the singularities,
All the singularities,
All the singularities,
All the singularities,
All the singularities,
All the singularities,
Get asymptotes up!

Up on the graph, curve just broke up,
Each side doin’ its own little thing.
Wanted to rip, not a nice smooth trip,
Across that singularity.
Left side goes up, right side goes down,
That’s one bad disconnection.
Calculus got broke, MVT gonna choke,
Your limit just D. N. E.

Cuz if you like Calc then you shoulda had a finite limit.
If you liked Calc then you shoulda had a finite limit.
Don’t be mad ’cause ya was indeterminate.
If you liked Calc then you shoulda had a finite limit.

Divide by O-no-no-no-no-no-no-no-no.
Divide by O-no-no-no-no-no-no-no-no.

One of those “circle of life” things

Sigh. One of my favorite web comics, Brown Sharpie, is at an end.  After three-plus years, toonist Courtney has decided to cap those noxious fumes and focus on newer and more exciting things (like grad research!  and beer!  and kittens!).  We’ll miss you over here at komplexify!

See you in the funny papers, Courtney.

However, in a comical application of Newton’s Third Law, as Brown Sharpie is leaving I’ve been introduced to a new web comic, Saturday Morning Breakfast Cereal. It’s a bit less “classy” than BS, but no less funny.

Happy giggling.

Cinemathics

Of course we didn’t watch Alvin and the Chipmunks 2 last week. We instead made it through some of our Netflix queue instead.

Paranormal Activity

Paranormal Activity is about a haunting in a typical suburban home, whose paranormal activities seemed to be targeted towards a girl; in an effort to document it, they decide to record the increasingly spooky supernatural circumstances themselves with video. So, essentially,

Paranormal activity = Poltergeist + Blair Witch + a tripod

I don’t know how spooky this would have been in a ginormous, state-of-the-art stadium-seating uber-theater, but this movie about the ghostly goings-on in a suburban home is perfectly suited for viewing at midnight in the basement of your own suburban home.  In many ways Paranormal Activity is what the Blair Witch Project was shooting for — an uncomfortably first-person narrative with its scares grounded in “reality,” fueled not by the horrible things you do see but by the horrible things you imagine happening in the places you can’t see — without all the nauseas-inducing jerky camera work.

The Queen B and I found ourselves hooked after the first “event,” and jumped appropriately as the haunting became progressively worse, all the way up through the movie’s scary and unexpectedly violent climax.  In fact, my only gripe with the movie is its very last second.  (Spoiler alert!)  Why did they feel the need to cheapen the movie at the very last moment with Katie’s crappy CGI spooky face?  Wouldn’t it have been just better to let her crawl back in bed as if nothing happened, after which having the camera mysteriously cuts out?  Ah well.

Knowing

A distressed widower discovers a supernatural means to predict upcoming disasters, although this doesn’t necessarily mean an ability to stop them; however, as the situation becomes more dire and his family becomes more threatened by a shadowy collection of other-worldy figures, the supernatural events lead him to regain is lost faith in a higher meaning of the universe.  So, in a nutshell,

Knowing = Mothman Prophecies + Signs + an EBM band

I always like the movie’s directed by Alex Proya (think The Crow, or Dark City), and Knowing is no different.  It’s certainly not as moody or cerebral as those other two movies, but it moves at a good pace and maintains a moody of general uneasiness, occasionally punctuated by top-notch action sequences.  (The crash landing of the plane is an excellent example — it’s possibly my second favorite single-take cluster-f*ck action sequence, trailing the forest-ambush-sequence in Children of Men.)  And you’ve got to be impressed with a movie that ends with the hero complete unable to prevent the cataclysmic, fiery death of every living person on the entire planet, save two.  Spoiler alert, by the way.

As a side note, it also features what might be the funniest bit of dialogue concerning the modern scientific method, which goes something like this.

Scientist 1: Hey, you remember that girl I tried to hook you up with?  Ph double-Ds?

Scientist 2: Is it even ethical to talk about your sister-in-law like that?

Scientist 1: What?  It’s been independently verified and peer reviewed.

Star Trek

In the new Star Trek reboot, a ragtag team of rebels (including the disreputable hunky one, the young one verses in an ancient alien tradition, and a hot chick) team up to stop a group of intergalactic baddies who, armed with a massive spacecraft capable of blowing up entire planets… particularly those populated by peaceful peoples. That is,

Star Trek = Star Wars + miniskirts

It’s clearly not your father’s Star Trek: Kirk and Spock hate each others’ guts, the planet Vulcan gets obliterated halfway through it, Starfleet officers are trained to shoot first and pontificate on the issues of freedom and equality later, Spock’s mom is Winona Ryder, and so forth.  That being said it’s still a fun popcorn flick, and it’s peppered with a couple of nods to old-school Trek fans, including a  gleefully nasty fate for the red-uniformed dude on the away team, or the fact that Leonard Nimoy actually appears as the Spock from the original — i.e. your father’s! — Star Trek universe.

Fermat’s Room

In the Spanish movie Fermat’s Room, four mathematicians (well, three mathematicians and an engineer) are invited to a secret meeting to discuss the “greatest enigma of all time.” Instead, they find themselves stuck taking an IQ test in a room tht starts to shrink when the questions aren’t answered quickly enough.  That is,
Fermat's Room = (SATs) intersect (Trash compactor)
The movie does a decent job generating tension by combining the twin fears of claustrophobia and word problems, although it’s primary mystery — who arranged for the four to meet in the slow death trap, and why — is a little hokey.  That being said, any movie in which a proposed proof of the Goldbach Conjecture plays a fundamental plot point is definitely worth taking a look at.

It also offers this final bit of advice, which coming from a foreign movie I found altogether more amusing:

Engineer: Pressure is unpredicatble.  It can turn coal into dust or a diamond.

Mathematician: Was that Archimedes?

Engineer: No.  MacGuyver.

Frostbite and the L’hospital

I clicked on the Weather Channel this morning and saw that this morning’s temperature was

Moments later I stepped outside, and discovered that whilst 00 is of indeterminate value in calculus, in meteorology it means really frickin’ cold.
