the person at 0:54 has a REALLY dilated iris. Even after adjusting to the light. Is that the effect of pot or something?

It's been many years since I studied physics. What does the lowercase gamma in the bottom left represent?


Me to, I think the answer is in here, but eff if I can remember.
Edit: ok I think it is the "Lorentz factor" . 7.089 Lorentz factor is 0.990 ratio to the speed of light (or very very close)


Lorentz sounds like it to me too. There are only a few other choices it could be, but I don't see them really relating very well to the what's in the video (gamma brightness for the "video", or gamma radiation factor from nuclear sciences--both I highly doubt).

Lorentz transformations (which is linked above by @GeeSussFreeK ) would be the way you would calculate many of the dilation effects caused by relativistic effects traveling near the speed of light.

Traveling at the speed of light you would have a pinpoint in front and in back. The light up front, the size of a point and basically nothing behind, as it would be shifted to very low levels of radiation. If you're going at the speed of light you wouldn't be doing any calculations as time has stopped, but from your vantage point everything happens at the same speed. As you slow down though far from the speed of light, in less than a second you instantly see things change all around you depending on how long of course you had been going at the speed of light (if you had been going that speed for 10 years you won't see too much; but, what about one billion years--can you imagine...).

But, to you a second was still one second even at that speed, or any speed, even as time slowed down the closer you got to the speed of light. Everyone else will of course still count their seconds the same as well. Hence, relativity.

If you did go that fast, yet had mass you would be facing some HUGE problems. At the front you would find a tremendous amount of energy (I'd guess all of it would be shifted to the highest energy level; one huge one-dimensional jet of gamma radiation) and at infinite amounts. In other words, it's impossible to do it. that is why a lot of Sci-Fi uses space warping/tearing/etc... to connect yourself to another place, like a wormhole; or bend space in front and back of you like Star Trek and use warp.

Gotta love Einstein and his little revelation--and all revelations in science or otherwise that add to the understanding, the expanses created, broadening our horizons, windows to the wondrous mountains of the mind put into view, and all of reality's grandeurs still there to be conquered and our dreams explored. It makes this world just a bit more interesting and worth bothering to get up every morning and go about our daily routines.

The last bit about our mind expanding when we're in a new environment is the reason I'm addicted to living in other countries: time dilates, and I get more mental stimulation from every direction, and when I go home, my mind just isn't as stimulated, time flies by, and pretty soon I feel like I'm wasting my life. And it really is the same feeling as being in a relationship or not.

Can't agree with the coffee analogy though because all that does it make me paranoid and give me the shits.

Einsteinian Time Dilation is not the basis of GPS.

Time dilation had to be taken into account by GPS--because of how fast the satellites are moving (Einstein's Special Theory of Relativity)--and because the gravitational field of the earth is less at that distance (Einstein's General Theory of Relativity).

GPS & Relitivity

@GeeSussFreeK

Time is interesting, truly one of humanities and other animals, greatest sensory abilities via memory. In fact how our memory is stored depending on what type of creature you are can give you a wide difference in abilities. Like a fly out maneuvering your swat attempts. Truly time seems not to exist at all if there is no memory. You can also tell that our perception of time was never meant to work with time dilation; this showing that time is extremely relative even just by biological standards.

But, you must remember that if we all died tomorrow and on some distant planet a new species started to learn as we have. They will still have access to the greatest library ever known: The Universe. Does that make time exist? Is it merely just an artifact? Time seems to have an "artificial" standing, as this new species will not see it at "one second" nor will they perceive "one second" the same as us. Time exists, but what is your duration, one tic = the time it takes for the Universe to go from 3k Kelvin to 0 Kelvin, or a few seconds = as we see it?

Much like temperature and other sensory based interpretations of reality. I think it does exist outside our perception, but it could be better stated than is. Perhaps using discreet energy packets in relation to the speed of light interpreted by general relativity for the system, etc... (a much more precise definition of time is using the mechanical nature of particle physics and sharing it with another system, much like nuclear clocks).

Nooooooooooooooooo. I'm saying Leno allowed NBC to have their way with them after he, Leno, forked Conan.

Would you be relaxed if your caboose was dilated to 9cm courtesy of NBC? You can't fork people over without getting forked in return.

>> ^MaxWilder:
Ya know, most of the time when people talk about how much Leno sucks, I kinda shrug and think "He's not that bad."
This video shows exactly how bad he is. He cannot even keep up with Louis. I mean, you can't match a guy who is in mid-rant, but you could do better than push to your next scripted question, or repeating the last two words of his last sentence.
Leno just looks so awkward doing a job he's been doing for almost 20 years. You'd think he could relax and go with the flow after all this time. Maybe that's the problem. He's incapable of relaxing when the guest takes temporary control of the show.


Whaaa? You're saying Leno was screwed over by NBC? I think you are confusing him with Conan. NBC treated Leno like a prince.

I just think they have a target in mind. For example they probably wont go into pentathol and then demonstrate it by euthanizing an animal.


they don't need to but i'm pretty sure if they covered it they would not shy away from saying "its used to euthanise animals" - not alued to that as its main usage but then skip around saying specifically what its used for by only describing what it does on a cellular level. also for example why bring up Viagra if all you are going to talk about is the raw chemical and how it dilates blood vessels when Viagra is marketed primary as a erectile disfuntion drug?

the word penis/erection or discusoin on the scientific raw facts of sex should not have a age restriction on them. the problem hear is simply that they alluded to something rather than just saying it which is out of character for the videos where they have no problem specifcly saying the use for other chemicals or what they do to things on a practical level.

No one thinks thay should have gone into full graphical detail on how penises and sex work ( although that is lagimitely as interesting as any other thing) its just a case of being mature and not continuing useless cultural hangovers.

Real answer - It's a 10cm diameter ring he uses to tell when a cervix is fully dilated.

Jesus is cool but God is a prick.

Also, what the fuck is up with cartoon makers and dilated pupils? That chick looks like she's on ecstasy.

I have just reviewed this several times in deference to your observations/perceptions. I'm sorry, but I discern no expression changes at all start to finish, no whisker movement, blinking, nostril dilation, etc. There is an artifact of a shifting nature however. Notice the movement of the object. It is purely vertical. Quite unnatural. Originally, I perceived it to be possibly 2D because of the rigid unnatural movement up and down.

With all due respect, however, I could be bonkers. Well, that may be beside the point.

Enjoy.

Ya'll do know it's not a real cat, right?

Looks real...it makes very subtle individual facial and eye movements that you can see. So if it's a puppet it's better than any puppet I've ever seen ever, must have a bout 20 servos in it's face.

also a little weirded out that the cat doesn't have what i call 'the big-eye' where their pupils dilate to that extreme point. you know, where your hands and fingers are suddenly targets...

I think every one in here should take a moment to understand how things die. It is highly debated, but is that fish dead? Maybe, maybe not. What is dead? Dead when the person observing the former cannot sense signs of life (pulse, eye dilation)? Or is death when a brain no longer carries electrical signals; moreover is death when the cerebral cortex no longer functions.

How long is a severed head still alive?

Below is some debate about the severed head issue. While I found the first link interesting, I was not satisfied. The Wiki Answers link seems to be more to the point. How long does a severed head retain life, perhaps a few fleeting moments. To an observer maybe seconds, or minutes. To the victim, no one can know; given the effects of time dilation.

http://wiki.answers.com/Q/How_long_does_one%27s_awareness_continue_after_the_human_head_is_severed_from_the_body

In short there is no humane way to die. Death is a dirty business. Some see this video and say it's not humane, some see the video and all but condone it. I see this video as an observation of the interaction between the macabre and desirous. Business as usual.

I like how he has dilated pupils.
