Has anyone been watching Supernatural? I am watching last week's Easy View, and I like it, but I wish I knew what had happened in the premiere. Can anyone summarize for me?

I really need to see Wedding crashers, and 40 year old Virgin.

I can't believe the numbers of you who haven't seen BC before.

Tep and who else?

KC...is hitting closer to home than I expected. But I love it.

So, I'm trying to watch the Lost catch-up show, and I'm not feeling it. Should I bother? Should I bother watching Lost anyway? I'm torn.

BC seems a little, I dunno, hatchet-faced to me. Gorgeous eyes but not on my list.

Once you've torn your ACL, MCL, and PCL, can't we just say he "tore his knee?" I mean, does he have any ligaments left?

In fact, there are seven knee ligaments, if I am counting correctly. They are the patellar, oblique popliteal, arcuate popliteal, tibial collateral, fibular collateral, and anterior and posterior cruciate ligaments. The MCL you're referring to is, I am guessing, the meniscus? Or medial condyle.

(Owning an anatomy textbook is a wonderful thing.)

Still, yes, I would say if you're up to three torn items in one knee, then just say that the knee is frelled.

OTOH, it drives me nuts when sportswriters don't differentiate between the rotator cuff and the labrum. One is basically fatal to pitching careers, while the other is not.

Anyone around who can answer a matrix multiplication question? Can't remember if the determinants of the two matrices to be multiplied can tell us anything about the determinant of the product.

Emily, the product of the determinants is the determinant of the matrix product.

eta: Perkins -- I watched it, and I think the key bits where that their father is a ghost catcher/demon hunter, and he's disappeared -- they're tracking him. DeanNotDean's girlfriend died/disappeared/appeared flaming on the ceiling the same way their mother had 20 years ago (which might have been what set their father off). There might be a journal or something they're using to follow his steps.

Last week's supernatural: they started 22 years ago when Not!Dean (Sam) was a baby. His mom gets up to check on him, sees a shadowy figure at the crib, thinks it's her dh, then hears the tv on downstairs. Walks downstairs, sees her dh sleeping on the sofa in front of the tv, runs back upstairs, screams. DH comes running, baby is okay, then sees blood drip on baby's face, looks up, wife is impaled to the ceiling and then bursts into flames. The husband and the two sons are saved. . . move on to 22 years later. Sam is hoping to get a scholarship to law school (as if) and is living with his gf when his older brother Dean shows up. Daddy was following up on a "White Woman" -- which is a type of ghost and has disappeared. Dean convices Sam to go out to check on Dad. They find the WW and why the WW was there and solve the haunting there. . . they don't find their father but they do get coordinates as to where he went. Sam returns home to discover his gf impaled on the ceiling -- she then bursts into flames. So Sam joins Dean to go look for Dad at the next place, i.e., where they were this week.

It amazes me that somehow, despite 22 years of hunting they still don't know what the thing was that killed their mother. Obviously, they need a Giles or a Wesley.

Emily, the product of the determinants is the determinant of the matrix product.

You sure? Bless you, cause that's exactly what I need to know. Why do neither of Mathworld's entries (on matrix multiplication and on determinants) tell me this?

Dude! That's Callum Keith Rennie!

Yeah, I'm hundreds of posts behind in Boxed Set. I'm sure it came up.

eta:

Emily, MIT thinks so.
