I think it was on TV.. probably Discovery or something, where there was this guy and he turned this snake over and you could sorta make out legs on its back but like they were squashed in to be part of the body. I wasnt paying much attention so I could be mistaken.
I'm just wondering whether snakes did evolve from lizards....

Thanks!! :)

There is no edge to space, if not correct me.
If so why must there be a beginning (edge) of time as it is essentially no different from spatial dimensions. If not correct me.
So why does there have to be a duration of the universe (magnitude in the fourth dimension)? If there is not a size of the universe (magnitude in the other three dimensions).
If you feel that the physical laws of the universe do not permit this why is it then that physical laws can not change or that there are not exceptions at certain quantities?
People often argue about this in the debate between big bang and creation but why can people not comprehend an eternity as they comprehend an unending strip of space known as a circle. Quite confused, please help.

does the uncertainity principle mean that there will always be an uncertainity in 'the values measured of some physical quantities' or does it mean that there will be an uncertainity in 'the values existent of some physical quantities'? both the statements are different from each other. the first means that the values cannot be certainly measured and the second means that there is no certain value existent for them.

surely the space shuttle isnt the best we can do, but will we ever know due to the costs? or are the space shuttle and all the little toys NASA makes the best possible innovations in space technology

I want to get my dog desexed & it will cost $88. But I am entitled to one third discount off that price. I'm not very good with maths.
It doesn't sound like it would be much.
Please help!
Thank-You!

Since the current estimate of the age of the universe is 13.5 bln years, how can we see galaxies that are 13 bln light-years away (as announced this week (7/10/07))? If the universe started at a single big bang point, our galaxy and the newly discovered ones would have to be moving away from each other at nearly the speed of light. And, if that relative speed weren't mind-boggling enough, wouldn't the severe red shift caused by such rapid relative motion render the visible light from those distant galaxies undetectable? Don't get me wrong -- I'm not trying to start a science vs religion argument here. I fully believe the current scientific theories about the nature and origin of the universe. I'm just curious as to this apparent paradox.

I read an article that stated that some astronomers saw some objects that existed roughly 500 million years after the big bang. Since the universe is roughly 13 billion years old is there a point in that exists where we will never be able to see that light? For example if our opitcal technology was unlimited would we truly be able to see the big bang? One note I do understand the fact that light travels at a certain speed and that after the big bang the universe expanded at an amazing rate. just having trouble wrapping my mind around this for some reason.

Fats and oils are commonly made up of triglycerides. When subjected to frying (i.e. at approx 200 degrees celsius), these triglycerides tend to polymerize. Suggest the mechanisms in which they could polymerize.

I would appreciate it if you can cite some journal articles to back your view. :)

Thanks.

So boost is measured by how much the air is compressed because when the volume decreases the pressure increases and if you increase the volume of air and compress it you have a higher boost pressure? Or is boost pressure how hard the turbo is working to pump the air? I read that on a website? Is this correct? How can you be producing more boost when at lower air masses than at higher air masses? Example 9psi@30lb/min 20psi@20lb/min How is this possible? Is it becaus eof turbine shape, design, weight, material do all those factors come in play? When there is more pounds of air flowing wouldnt there be more boost because more air is flowing so more air is being compressed? Or does it depend on volume rather than pounds? Can you please explain this to me in detail?

In a particular experiment to study the photoelectric effect, the frequency of the incident light and the temperature of the metal are held constant. Assuming that the light incident on the metal surface causes electrons to be ejected from the metal, what happens if the intensity of the incident light is increased?

A. The work function of the metal decreases.
B. The number of electrons emitted from the metal per second increases.
C. The maximum speed of the emitted electrons increases.
D. The stopping potential increases.

Enter the letter(s) corresponding to the correct answer(s) in alphabetical order. For example, if you think that choices A and C are correct, enter AC.
