Mutex's Claim That Speed Is Not A Ratio And Other Nonsense

Speed is a ratio, that is, it is a change in distance compared to a change in time. A change in distance is incoherent without a corresponding change in time. Meters per second is mathematically expressed as meters/second, or simply m/s but regardless of the mathematical symbolism, you will be hard pressed to actually divide the seconds into those meters and even more hard pressed to subtract seconds from meters. Someone might accuse you of using sophistry here, but I suspect you are just having bad luck when trying to think about these things.

 

Speed is a length of space over a length of time, it is not a ratio, in your case you are using meters per second, so 1 meter is the length of space and 1 second is the length of time.

 

We define time by the length of space, in our universe all we really have is time that is derived by the length of space, 1 day is the length of space traversed by a point on the earth, we call that 24 hours. 1 year is the length of space of one orbit around the earth. 

1 meter is the length of space of your arm, this is what we refer to as spacetime, which is of course time derived from the length of space. 

 

In relativity, the point is that the length of time (and therefore the length of space), varies, from place to place and as a function of velocity (speed) in that space. 

 

So two people can move at 1 meter per second, in their own space length, but not not be going at the same speeds. Because the length of the meter, and the second are not the same lengths.

 

That is the fundamental basis of relativity, observing that clocks measure different lengths of time under different conditions is the fundamental test that confirms relativity is correct.

 

Now you can justify this difference in the length of space any way you like, either geometrically and you can say that the difference in that length is due to curved or warped space, or you could just say that the length is just longer (stretched if you like) and is not geometrical but flat. 

 

But the length of 1 meter or 1 second is NOT A CONSTANT, but the speed of light IS a constant, the only way for the speed of light to be constant and the length of time to be variable is for the length of space to also be variable. 

 

You just have to get in your head that 1 meter per second for you is not necessarily 1 meter per second for me. Because 1 second and 1 meter are variable due to relativity.

blah blah blah

 

 

LOL

 

First it was “humans did not descend from apes” and now it is “speed is not a ratio”.

 

I suppose it will not make any difference, just as it didn’t in that other thread, but I will post a few very basic links for you that even a little kiddie might understand:

 

What Is a Ratio?

 

"In mathematics, a ratio is a comparison of two or more numbers that indicates their sizes in relation to each other. A ratio compares two quantities by division, with the dividend or number being divided termed the antecedent and the divisor or number that is dividing termed the consequent"

 

Ratios in Daily Life

 

"Ratios occur frequently in daily life and help to simplify many of our interactions by putting numbers into perspective. Ratios allow us to measure and express quantities by making them easier to understand"

 

Examples of ratios in life:

"The car was traveling 60 miles per hour, or 60 miles in 1 hour"

 

Knock knock it sure looks like speed really is a ratio!

 

Distance, rate and time

 

"A rate is a ratio that compares two different kinds of numbers, such as miles per hour or dollars per pound. A unit rate compares a quantity to its unit of measure. A unit price is a rate comparing the price of an item to its unit of measure."

 

"The rate "miles per hour" gives distance traveled per unit of time"

 

 

Yes, sure enough, speed is a ratio! But go ahead and double down, I need a good laugh.

Humans are apes. Yes we evolved from earlier apes but that's like saying bats have a lot in common with rodents.

Seems very much like you're trying to weasel your way out of being shown to be wrong, like you always fcuking do.

Do you still think two objects can't move over the speed of light relative to each other from the frame of a third observer? :)

Then call it a ratio, I don't give a flying fck, not interested in arguing with you, on something so trivial and pointless. 

 

It's nice to see A-wal also trying to explain to you that humans ARE APES, and ALL existing apes (including humans) evolved NOT FROM APES, but from a common ancestor.

At least you are still a moderator, so you can continue being a dik to everyone, and deleting things you don't agree with..

Have you been breaking bricks with your head?

 

Humans are apes is exactly what I have been arguing.

 

Did you even read my post #16 with the cladogram?http://www.scienceforums.com/topic/37012-my-idea-of-how-apes-turned-into-humans/?do=findComment&comment=386825

 

It is Mutex who has been asserting that humans did not evolve from apes.

 

Before you jump into the middle of an argument, you might at least read the posts and see who is arguing what.
