What makes a great picture, better than a good picture?

Hmm, not happy with that...lets try again<div></div>

Thomas, what do you mean by the "continuum"? I get the feeling that you've read some BS in place of regular physics ...

http://dictionary.reference.com/search?q=continuum

 

A dictionary is a horrible thing to waste.

 

The complete term is "time-space continuum."

 

Here's a bit more read on the matter.

 

http://www.west.net/~ke6jqp/spacetime/spacetime.html

 

Einstein, in his book on "Relativity" (pg 78) discusses it and refers to it as the "space-time continuum," So you'll need to reference Einstein and Relativity first before referring to Sci-Fi sources:)

Thomas, time is a physical quantity and it is not just human imagination any more than the physical world itself is. Animals probably perceive time just as humans do, and even if no animals existed, the world would still go about its business. Making philosophy out of theoretical physics is just silly. Theoretical physics is just mathematical models of physical phenomina. Whether a model includes some physical quantity is irrelevant: it is just a model. And I am unaware of any model of e.g. mechanics which excludes time.

"Thomas, time is a physical quantity and it is not just human imagination any more than the physical world itself is."

 

Since time doesn't exist, except in the mind of humans, your argument comes under the heading of "non-sensical" philosophy and needs to be considered wishful thinking just as is the concept of "time-travel."

 

Most folks have problems with the "fact" that time is a human construct so as to "define" their "existance" in the universe. Humanity "needs" this mental anchor to hold on to for emotional security purposes because they're unable to grasp the concept of timeless freefall.

 

There is no "physical quanity" known as time. We made it up and have since created cesium vibration standards to enhance the accuracy of this concept to mark our existance and nothing more. The concept of time serves our technical purposes very well but that's the only purpose it serves. Blink humans out of existance and so will go the concept of time.

Wishing you well.

Blink humans out of existence and so will go the concept of time.

 

Metaphysic wild card theory that attempts to understand the fundamental nature of all reality.

 

Theory without the concepts born of reality or practicality.

Which drugs are you guys on? I want to be sure that I don't take the same accidentally.

 

My recommendation is that you try to avoid letting your imagination take over and read a little science so that you get your feet on the ground instead of flying in the clouds.

. Which drugs are you guys on?

 

Hopefully, not make me' Mr Angry', and I'm really clever ' Drugs ',or 'I'll burst into tears if you don't think so', Ilky.

 

You did mention drugs, Ilky.

 

Temper, temper........this is a family friendly Forum.

Everything that we know is based on our senses. The science that we have is based on observations. If you say that everything we observe would disappear if we did, and everything in the world outside us exists just in our minds, then there really is no way of finding out what the world is like.

 

That's not in any way sound. We can only build our knowledge on experiments, and dismissing science just because there is a human element in all observation just doesn't lead anywhere.

 

Since ideas which are not based on observations can not be proved right or wrong, they are not science. Since all observations which we use have a human element at the last stage, we only have human data to build our science on. All knowledge is just human observations. What point is there to say that "time doesn't exist" or "space doesn't exist" or "matter doesn't exist" or "the universe doesn't exist" or "god exists" when no observations can be made to prove such a thing.

 

My temper is just fine, thanks, as fine as it can be. I just don't understand what you guys were taught at school, that's all.

My temper is just fine, thanks, as fine as it can be

 

Nice for you. I always liked Aristotle at school: inspired Alexandra to try to rule the universe.

 

Chill out photo.....<div></div>

Hey people, This string is good reading. I'm going to print it. But I feel the basic answer is: The mental act of making the choice "at that very moment" to record the image. Everything after that is just a reaction to the image.

"Which drugs are you guys on?"

 

When one runs out of argument, the name calling begins.

 

"My recommendation is that you try to avoid letting your imagination take over and read a little science so that you get your feet on the ground instead of flying in the clouds."

 

I posted an accepted definition, a thesis paper and the usage of the term "continuum" in a book written by Einstein himself. Went so far as to cite a page where he uses the term. This followed by support as to the use of Cesium for maintaining the US offical time clock and you state that I'm "flying in the clouds?"

 

You so funny.

 

If humanity were to blink out of existence, everything else would still be here except two things, humancentric thinking and time:)

 

Wishing you well.

Thomas, the "thesis paper" which you refer is just a web page, it is not a scientific paper.

 

Could you point to the referred scientific paper where Einstein or your favorite scientist claims that time exists only in our imaginations but other parts of the physical reality ("everything else") would continue to exist when we're dead?

 

(I did not run out of arguments, I just wanted to give you the option that you admit that you were not in your right minds when you wrote the above claims. As it is, it turns out you just don't know science or physics.)

As to how a reference of the unit of time is maintained, how does this come into picture?

"Could you point to the referred scientific paper where Einstein or your favorite scientist claims that time exists only in our imaginations but other parts of the physical reality ("everything else") would continue to exist when we're dead?"

 

That's my contention, not anybody else's. You're comment had to do with Sci-fi which I'm not into. I don't do fiction. And bless you, no I'm not a physicist.

 

It doesn't take a genius to know the whole of the universe keeps ticking, with or without our permission and anytime something is tied to the vibrations/oscillations of an object, (in this case, time), it's trying to tell you something; it's a construct.

 

Time is a recent addition to humanity's awareness as it's clearly tied into the revolutions of the Earth around the Sun and as humanity grew in intellectual sophistication, so came the sophistication of breaking up the transient of the Earth around the Sun. At one time and point in Earth's history, the Sun actually revolved around the Earth:) But Galieo fixed that and now the Earth revolves around the Sun.

 

Would time be the same on a plant revolving around a sun/star in Andromeda?

 

The point, time, if it exists, would have to be homogeneously the same, black holes excepted, in the universe and if our concept of time is tied into Earth revolving around our Sun, then how could we time a time transient, if on another planet, in a galaxy far, far away? Would we use their version, our version or would we need a universal time converter?

 

You see, humanities concept of time, being tied into Earth's revolutions around the Sun; 365.25 days/yr and slowing, the spin of the Earth, called one day because of the "sunrise/sunset" phenomenon and the arbitrary assignment of twenty-four latitudes (time zone) because of the Earth having an approximate circumference of twenty-four thousands miles and this equaling the speed in which the Earth spins on it's axis, is where our concept of time has come from.

It's all an easily identifiable construct as to where this pseudo phenomenon came from, what it's purpose is; "To define our existence in the Universe." and to understand that it doesn't exist, therefore it can't be controlled in the sense of calling it back or accelerating into it.

 

It really isn't that difficult of a concept in which to perceive. People have gotten so caught up in the concept of time that they've forgotten, it never was real cause it's simply a sophisticated, human made, invention/concept/creation (whatever) based upon a spinning planet, orbiting a star while hanging out in a galaxy somewhere in the Universe and nothing more.

 

I think the concept of time travel, "The Time Machine" and H.G. Wells were good for each other as that was real..... Sci-fi. :)

Right! And gravity didn't exist until Isaac Newton came along. Uh huh.

Thomas, you're confusing time with the unit of time. The unit of time is defined by humans, but the absence of humans does nothing to time itself. If we remove all references of 1 meter (the unit of distance) (e.g. markings on rulers etc.) from the world, nothing would happen to distances anywhere in the universe. They'd still be the same. Same with time, whether you define its unit to be one revolution of Earth around Sun or another planet around another star, it just doesn't matter at all to physics. It's just a matter of how units are defined. Time is not a second or a year, these are units of the physical quantity time.

"Time is not a second or a year, these are units of the physical quantity time."

 

Excellent point:) And just how are we suppose to recall time if it's undefined:) LOL LOL LOL

 

You just made my point about how time is a contrived construct and without humans to define it, it doesn't exist. There's the continuum and nothing more.

 

A dog can chase it's tail, I can't:)

Nice photos, apart from the out of focus bird shot...and the over saturated thing.

 

Fortunately tempus moves on and this thread will disappear.

 

But, it was a sort of fun.....

Think of it...when you are associating the word 'great' you are actually doing either of the

two things....1) You really find it good, something 'You' have not seen before or 2)

Nodding along because you know people call it great and there lies the answer. A photo

by the great Masters has to be taken in context of the time when it was made....they may

continue to exude the same charm or not...that won't change its greatness because

'greatness' is like folklore....it never dies. So while There are probably a hundred Ansel-

like photographers today they cannot ever match upto him because he not only did

something beautiful...he did it first. So if you are searching for greatness try thinking on

your own....a signature which sets you apart...thats the basic criterion...how high up the

pedestal you will be put by people depends on how beautiful that signature is....but

without the signature, that spark of newness/individuality there won't be any pedestal at

all.
