After years of speculation and wrangling over his remains, Kennewick Man turns out to be closely related to contemporary, local Native Americans after all. Discovered near Kennewick, Wash., in 1996, the skeleton ended up in a tug of war between tribes in the pacific northwest who wanted to bury the remains, and scientists who wanted […]

Our solar system is awesome.

The European Organization for Nuclear Research, or CERN, has been releasing portions of its research to the public for years. This week’s massive 300 terabyte dump of Large Hadron Collider (LHC) data is the biggest yet by a long shot — and it’s all out there, open source, free for the exploration.

Almost everyone has their smartphone in a case of one kind or another. Beyond simple protection, finding a case that can charge your phone on its own, but doesn’t feel like it’s also adding a couple pounds to the phone’s weight is the tricky part. Billed as the world’s thinnest battery case, the ThinCharge iPhone […]

You never know when new projects, ideas or opportunities can drop into your lap at a moment’s notice. That may require you to learn a new programming language like Python. Or maybe you need a primer on 3D game development. Or you might realize you could use a serious brush-up on iOS mobile creation.Point is, […]

Isn’t it about time to stretch what your Mac can do? I mean, you’ve got plenty of great programs now…but don’t you think you could use some new tools to get your creative, analytical and organizational juices really flowing? It’s spring, so we cleaned up a whole bunch of super-cool apps lying around and packaged […]

My algebra book was all about trying to find its ex.

I wonder why.

I think a(t)=√(2)sin(t+pi/4) and b(t)=√(2)cos(t+pi/4). The answer to (d), of course, is Brian.

Actually, the things the student is asked to show are unprovable. If

a = c sin (q)

b = c cos(q)

then all of the conditions are met, but we know nothing about the relation between q and t. In other words, it’s one equation in two unknowns. Therefore, we can’t find the time derivatives without more information.

You missed that b'(t) = -a(t) gets added as a second premise. That’s what really ruins the relationship, romantic comedies notwithstanding.

An exercise in circular reasoning….

… Which means that they will like each other a quarter of the time for all eternity. Moreover, they can predict when the quarter of the time when they will dislike each other, and so plan for this while they are on good terms.

Looks like a better basis for a relationship than many…..

If one or both of them can find a job the requires predictable and compatible times away from home (working in a lumber camp two weeks on / one week off, that kind of thing), it could be a thing of beauty.

I didn’t actually do the math – what is the cycle length? Would the requisite job schedule in fact be incredibly weird?

Shay Guy got the math basically right, so this couple goes through an entire cycle roughly weekly.

That is one high drama couple.

Of course, as any moron with a PhD mathematics could see, the same mathematical equations presented here could model a predator-prey relationship.

The use of predator-prey model for a romantic relationship is decidedly odd. Do you mis-understand what a woman typically means where she says “My boyfriend eats me” ?

I think the lesson for me here is to finally forego mathematics as means in understanding one’s boyfriend/girlfriend/husband/spouse (singular/multiple) …mine and/or someone else’s…

Boing Boing is going to get sued by E-Harmony for publishing their secret algorithim

Math homework!!!

I think this math problem is a reference to a paper by Sergio Rinaldi that attempted to do a similar mathematical analysis of the unrequited love of Petrach for Laura by analyzing Petrarch’s poems. http://epubs.siam.org/doi/abs/10.1137/S003613999630592X

That analysis also results in a cyclical love dynamic (the name of my new band), though since it was unrequited the cycles were mostly Petrarch’s.

I wish they had added the source.

I guess if they told us the secret formula for Alice and Bob’s affair, they’d have to kill us.

The correct answer is, “None of your beeswax!”

As if relations were not tricky enough as it is already . . .
