That paper wasn’t nearly as sexy as I thought it would be and I almost couldn’t masturbate to it.

I am also disinterested in porn involving fat nerdy women wearing strapons.

The waves object of this study are not “accoustic” but “sismic”.

Accoustic waves are the ones you can hear, the rhythmic “fap, fap, fap” which is audible and propagates at the same speed of sound as the moans and other sounds.

You’re calling BS on the “disinterested” part?  
I would have flagged the “watching porn” part and questioned whether he was an actual observer or a participant - probably both.  
I can’t believe I actually posted in this thread

ie When having sex, no gas is ever ideal?

Big-ass zits or big ass-zits. In this case either applies and I suppose it makes the joke less funny.

I would love to see this scenario discussed in a text book:

“A transverse wave traveling along Shaniqua’s fat ass is given by the equation ASin[k(x-vt)]. At t=0, a force applied at the buttocks produces a displacement of 14cm…”

This is so much more funny because I have a test tomorrow on wave equations and interference. 😃

Only on the SDMB could a thread involving asses and sex incorporate a minor side conversation about grammar intricacies. GAWD but we’re a bunch of nerds. A bunch of sexy, dirty-minded nerds. 😛

If you drive the fat from two different points, can you create a line of nodes across the buttocks where there is no displacement at any time?

Show your work.

Thinking about continuum mechanics, dancing around Wiki.

This is, overall, a problem in finite strain theory, right?

I ask because the topic here, as a drift of OP, and perhaps returning to it, is fascinating to me at the moment.
