Because their saliva contains many useful bacteria, including ones which effectively take care of the e-coli, so yeah, they're just cleaning themselves.

Oh what the fuck man?? So us HUMANS could lick our asses too if we had bacteria killing acids in out spit? damn. we so left out. LOL jk.

So y ou cold just rub your hand on your dogs mouth instead of using that antibacterical lotion shit right? ;)
 
I understand how kinetics explains things getting solid. I don't understand opaqueness on a molecular level though, and I don't see how kinetics (esp not kinetics alone) explains it.

Any liquid, when it is cooled, gets solid because of kinetics. What is special about fat that makes it opaque when other liquids freeze clear? THAT's what I want to know.

Do all esters become opaque? Why?
 
Cuz its starts out opaque before it gets lipo'ed off the corn/soybean/vegetable's ass and thighs, duh. its just goin back to its natural state

;)
 
Well, and this is just a guess (based on reasonable knowledge of chemistry), I would say that the opacity is mostly a result of density. As a liquid, lipids are able to move freely about and as such are less likely to be struck by light at a wavelength that can be absorbed. Even as a liquid though not all of the light gets through.

As a solid the lipids are much more closely packed, and are bound together with some intermolecular bonding. This means that any photon (of a wavelength that the lipid absorbs) will be much less likely to pass through and will more likely be absorbed. Note that for lipids with other gunk in them (such as butter) are usually much more opaque than straight lipids (such as clarified butter). Here the additional opacity comes from the suspension of milk solids (mostly sugars and proteins-- which absorb their own characteristic frequencies of light). Compare regular butter and solidified clarified butter-- the clarified butter will be less opaque (like other oils).

The ester part just means that there are more than one type of intermolecular bond holding the solid together, making it more rigid than if it were just a straight hydrocarbon. Plus the stronger intermolecular bonds can themselves also absorb light (although AFAIK it's still not in the visible range).

My question: why are spectator sports so damn popular? I can understand how someone can find it fun to play sports (not that I do), but how is it entertaining to watch some bunch of steroidal goons pound into each other in an attempt to get a ball across a line? And why are these people worth more than useful members of society?

Ofcourse! I do it all the time.

That would make sense...so liquids which remain transparent, contain molecules not so good at absorbing light. Thanks!
 
Input on the subject of opacity:

I think it's to do with the molecular lattice structure. When wax is melted, its crystalline structure is lost; ie. it becomes amorphous (non-crystalline and completely random). A property of this amorphous liquid is that it lacks the ability to absorb visible light.

When wax solidifies, it will return to a semi-crystalline structure and a property of this is more opacity. We can tell the structure is semi-crystalline because wax is slightly translucent.

A good example of this. Transparent glass (silicon dioxide) is made from opaque sand (silicon dioxide). The only difference is that glass has an amorphous structure and sand has a crystalline one.

I wish I was able to explain this in terms of light waves and electron shells.
 
Why do people in California freak out when you call them from LA and say, [arnold s. voice]"Zis is ze fuucha calling, if you vwant to leve come wif me naw!"?
 
^^Cuz they think its the orange spikey alien from Spacecataz/aquateens calling and they always wanted his autograph. you know how girls scream alot when they see hot famous guys right, its liek that, they get real excited.
 
what is the difference between "no turn on red" and "wait for green" signs? Don't they really mean the same thing? What about the traffic lights that have a "right turn signal" notation? Do you have to wait for the green arrow or does the green arrow just mean that you don't have to yield to traffic when making your right turn? I don't mean green arrows that direct traffic across an on coming lane, I mean green arrows that direct you to enter a roadway from a perpendicular road without crossing over another lane of traffic first.
 
Ataxia- I don't know if lipids have much in the way of crystal structure, but in the end even if they do it's the same argument more or less. The higher degree of intermolecular bonding increases the molar absorbtivity of the material for (visible in this case) light. As well, the more bonds (of different energy) that are formed will allow for more frequencies of light to be absorbed, decreasing the fraction of light that passes through the material.

I was just wondering if there are any flash games that are as much fun as "Kitten Cannon" and also as violent.

I've been through this site a hundred times, but I still can't find anything quite as great as Kitten Cannon. I'm basically looking for extremely an extremely simple game like this with lots of blood and easy controls.

TIA

certinly not crystaline in the sense of a diamond. But solid lipids are certinly a more ordered, more dense (most significantly) material.
 
That's what I mean. They don't (AFAIK) have a specific crystal structure, but are rather a random jumble of molecules held together by fewer intermolecular bonds than if it did have a specific crystal strucure. That doesn't mean that it isn't more dense or more ordered than the liquid state, but it does mean that the molecules aren't in a repeating, ordered geometric arrangement. The hydrocarbon chains move around too much in the liquid state to all be locked into the same position.

However, the opacity of the solid as compared to the liquid state would be a function not only of the intermolecular arrangement in the solid state but also the structure of the lipid in question and to a lesser extent the exact spatial arrangement of the hydrocarbon chains. Again, my specific knowledge here is limited, but since induced-dipole-induced-dipole intermolecular bonds are so weak, I wouldn't be suprised if there was still come movement of the hydrocarbon chains within the solid state (especially for the longer chain lipids). Plus I would imagine that the fact that the hydrocarbon chains would be ordered more or less randomly would allow for the highest degree of opacity, since the absence of any structure would greatly reduce the likelihood of a molecular 'tunnel' that would allow a path for light to pass through the material unaffected.

And Captainballs: Kitty Cannon is quite possibly the best flash game ever created. I saw a tribute to Raiden on ebaumsworld that was pretty good, but I could (and have during exam season) spend well over an hour launching kitties across the screen.

KITTY CANNON IS THE SHIT!!!

BUt i don know any other ones as good. =(
 
My high score right now is 1,938. i seriously don't know if it'll ever get higher than that. Are there any sure fire strategies? I doubt it, but it never hurts to ask.
 
yo, i got 2100 on that shit one time. hell yea!


the best setting for the cannon angle is at like 24.5 thats wher ei get the best scores. lol.
 
once i happened upon a mystifying conundrum of physics and magic.

whilst cleaning out my pantry a few years ago, i found a six-pack of some weird hippie soda, 'natural' raspberry-vanilla shit. it could have been anywhere between two and eight years old. i'm sure it was neglected because i would never voluntarily have a beverage that wasn't brown and caffeinated.

when i actually picked the pack of cans up, i noticed immediately that it felt a little funny - lighter, and unevenly distributed. i assumed that one of the cans had spilled, somehow, but there was no trace of color or stickiness or water damage anywhere near the former location of said sodas.

upon examination of the individual cans, i discovered that one of them felt like air. i shook it to see if i could hear any drops rolling around, but no. appearance-wise, this can, like the rest of its brothers, looked like it was brand new. not a dent, not a surface puncture, nothing. the pop-tab was securely in its 'closed' position, and the top surface was still convex.

next step, naturally, was to immerse the can in water and check for air bubbles. not a single one. the can floats right back up to the top of the sink once i take my hand away. it's a completely empty soda can with absolutely no discernable means of fluid escape.

so yeah. wtf?
 
lots of times, at the end of a production run, a company will ship an empty container rather than make a new batch of product to fill it. I've seen it more times than I can count, across all maner of products (soda, ice cream, tv dinners, boxes of rice, et cetera).

They usually get spotted and sent back for reclaimation by the stockers, or the customers, so no harm no foul. You got fucked. ;)
