Is it possible to define a set that doesn't include the empty set? I see the phrase "the empty set is a subset of every set" thrown around quite often, usually with some form of proof accompanying it. However that seems to fly in the face of examples like:

A = {B | B != {}} or A \ {{}} (I apologize if I've tripped over any notation here, but I think you get my point)

Is this just a case of lies to children[/tvtropes] on a large scale? Or is there just some weird contradiction that we've codified into the base of our mathematics as often happens with things involving "nothing" or "everything" or "infinite"?

What advantage is there to having organelles be membrane bound as opposed to just having them free-floating within the cell?

I know the answer to this one.

Basically a lot of the operations that organelles carry out require specific combinations of chemical reactions, often with further environmental limits to drive those. If they didn't have membranes then you run into problems with the chemicals from one organelle interfering with the other, either through the chemicals it is producing or through its conflicting environmental limitations. For example some of the reactions in organelles are driven by specific pH values. If none of the organelles had membranes, than those same pH's would definitely be interfering with things like DNA.

Additionally some organelles need those membranes to work as "targeting" mechanisms as well. For example without a membrane lysosomes would just be free floating clumps of hydrolase, wrecking whatever they happened to break into instead of only destroying specific things.

Lastly there are a handful of organelles that have held onto their membranes more because they were originally separate cells (and thus had their own outer membrane) and have simply become internalized over evolution, such as mitochondria.

[Sheb]

Yeah, and then sometime the membrane is needed for chemical reaction, the way the mitochondria needs a proton gradient at the membrane to drive the synthesis of ATP.

Every headset I get explodes into parts like a grenade swallower in a terrible accident, so I probably can't help you there.

Honestly I'd suggest going with a Turtle Beach headset (not all of their models are several hundred dollars) if you can. Additionally they've got some labor day sales coming up this weekend, so you can probably get some nice discounts if you buy soon as well.

Quality wise I haven't been able to find any problems with the one I bought, and while mine is on its last legs at the moment I've owned it for almost 7 years now, with the only physical problems I've had with it being that at one point one of the ears came unscrewed from the rest of the headset. (Of which fixing was simply a matter of taking the ear cover off, unscrewing 4 screws and screwing the main screw back in, then putting it back together again, a quick 3 minute fix with some screwdrivers).

[i2amroy]

Also, they have more cable than I know what to do with.

Yeah, that is one of the disadvantages of buying headsets that are designed to reach all of the way from your couch to the console plugged in to your very large TV.

... but. Hair is down there. You don't even have to go in for that?

Anyway, would you be able to tell us what CD it is? That might help.

Is there an easy way to extract the cookies from a chrome session? I've put a decent chunk of hours into a a clicker game, and realized too late I was in incognito mode.

why didn't i listen to my food advisor oh gods what have i done

[Graknorke]

If you were to read them with a javascript command you could probably copy them down as text and manually modify them later.

If you're worried about losing your progress, I think there's a "Save" button on the page to save your game as a chunk of text which you could then theoretically reload from. Never tried it but I assume that's what it's for.

Head hair.

[Sheb]

I'm working on a "St Sebastian enjoying his martyr way too much" costume. What's the best way to get rid of a lot of torso hair (if possible not too painfully).

[Arx]

Electricke hair trimmer. Most atomic razors not designed to be pocket-sized have one that folds out.
