Can you completely destory one of the three dimensions of breadth,lenght and depth?

question: But is that not using zero as an arbitrary placemat in a string of positive and negative temperature values?
As I understand it "absolute zero" (state of zero energy) on the Kelvin temperature scale = -273.15 C

An arbitrary demarcation. We can make zero represent a value, but it does not describe a value in and of itself.

How so? [quote[Roman Numerals: 714 = DCCXIV [/quote] (5+2+2)+(10+4) doesn't sound that problematic to me.
The Chinese can calculate large numbers just about as fast on an abacus as a person having to input numbers into a computer to arrive at an answer. Some idiot savants can do it even faster.

This is not to say that shorthand is not useful in mathematics, especially in very large numbers. But it does show that accurate mathematics can be achieved by several methods, each for specific purposes and applications. What happens when our computers run out of energy? How would you pay for your grocery bill? How many people do you know who still have to count on their fingers, but simple monkeys and many other animals can already recognize the difference between more and less, as well as humans, by a form of fundamental intuitive ability to count (without the use of numbers altogether). IMO, fundamental mathematics are part of natural evolution itself and everything is attuned to mathematical functions in some fundamental way, from atoms to the brainless slime mold..

What's the difference between zero degrees and one degree and minus one degree? How is zero less of a value than one or minus one?

 

It has no value by definition. We can use it arbitrarily as a demarcation or point of departure, IOW a number.
But the number is defined as having no value in and of itself.

I am not disputing that it is a real even number , it is just defined as having no real value..

 

A curiosity , but has nothing to do with the OP .

 

I am just going with the flow of the conversation. I don't think I introduced this diversion.

 

Yet you encouraged this diversion .

 

As I said I go with the flow. My mind is like water and I try to see things from different perspectives.
Though I do believe it tangently related to the OP. But it is up to the moderators to decide what is relevant. I am happy to follow their advice.
But if you want to go back to strict parameters of the OP, lead the way.

 

Tangently related to the OP , How ?

I'm reading .

 

From your post # 261 in the thread "a universe from nothing"

 

I still don't get the connection .

Bring it all together Write4U , what you are saying ...

 

Not being a scientist, I have to gather some of my intuitions on this and then attempt to express them in a coherent and logical sequence. Even then I may be completely wrong, but I always loved logic problems, which were of course solvable. Here I might well end up with logical contradictions., but the fun is in the trying.

Give me some time, I'll need to do just a little (a lot) more reading....

No problem , the duration is up to you .

In furtherance of our Segway into temperature, I want to continue that topic in the thread "A Universe from Nothing".
Hopefully see you there? Especially Mr.Penner, I need you input on this one.

 

Go on

 

see; A Universe from Nothing.

No, it has a value of zero by definition - just like one has a value of one by definition.

And that point of demarcation has a real-world value - e.g. 0 degrees Celsius or 0 degrees Fahrenheit or 0 degrees Kelvin. Zero can have (at least) three different real-world values - just like 1 degree Celsius and 1 degree Fahrenheit and 1 degree Kelvin are three different real-world values and -1 degree Celsius and -1 degree Fahrenheit are different real-world values. There is no fundamental difference between zeo and one. There is no way to distinguish between them except by the size of their values.

No it isn't. It is defined as having a value midway between 1 and -1. Whatever quantity that value represents, it is a real value, just like 1 and -1.

 

It has to do with the OP because "destroying" a dimension is different from a dimension having a value of zero. A dimension with a size of zero is still there.
