Black is the absence of color.

neither Zero or any other numbers actually exist...but like the term infinity they are used as points of references as a way to measure a reality ...zero is used to measure a possible non-existance of reality

If you go down that path you cannot prove to me you exist because we all may well be someones dream and when he/she/it wakes up we are no more

Now if you exist then everything else with you exist if not then not. But I don't care either way science has already eaten half of my existence

the only existence that can ever be proved is the existence of yourself to yourself and no one else because everything and everyone else may in fact be a dream

and that's why infinity ends once you reach the end of it

most of what you say is correct except the final sentence
for to reach the end of infinity it is necessary for the dream to end but not sufficient.

infinity is born of mathematicians requirements and unfortunate they used an existing phrase which was meant as limit less . what they wanted was a way of saying a large number which is so vast that if you added as many times to it the vastness of it consumed itself. they couldnt keep saying that every time they wanted to use the symbol so they chose infinity Unfortunate.I can't talk advanced Physics or maths without knowing the background of the audience. I hate loosing people in discussions.It looks as though one is showing off.

Black is the resultant of consumption of all primary colours
very much similarities exist in explanation of infinity with the colour black.

why is it necessary for a dream to end?..the only rule that a dream requires is that you dream it



infinity is actually born because of a lack of mathematics and falls more in the realm of assumption..if you can mathematically measure the reality in question then there would be no need to call it infinite because you mathematically know it has an end ..so when one resort to assuming the distance or vastness of a reality because they have no way to measure it then that is when one use the term infinite

You are thinking of pigments. Pigments reflect and absorb light.

Black pigment absorbs all of the colors of the light spectrum.

Color is just reflection of light.

Black absorbs light. When you mix Red, Yellow and Blue pigments together the resulting pigment is one that absorbs all light.

JB

little knowledge is dangerous go and read your physics enough said

Color is reflected light.
Black is absence of light.
I have been an artist for 40 years.
Nuff said.

JB

Color theory states clearly that JB is correct in her assessment...

Black is indeed the absence of all color. The absence of all refracted light.

Any number divided an infinite number of times must have a value of zero.

Unless your taking a calculus course. Then it can actually have a value.

Are you familiar with Gabriel’s Horn?

It’s a mathematical object whose internal surface area is infinite. Thus it requires an infinite amount of paint to paint its interior surface.

However, it only has a finite internal volume. Therefore it can only hold a finite amount of paint if used as a bucket.

Seriously, this is true.

It’s called Gabriel’s Horn

Thought of as a bucket it can only hold a finite amount of paint, but it requires an infinite amount of paint just to paint its internal surface area!

Believe it or not, within the definitions of mathematics this is not a paradox.

That does not make much sense. Please don't ask me to paint that bucket. Hey instead of painting the interior, just fill it with paint then.

JB

I can't find a connection to the dividing of numbers and the nature of the color black. For that matter, I can't find a connection between the color black and infinity.

I must have missed something. I'm confused.

@ JB...

Two separate statements covering two separate earlier statements.

Gabriel's horn is illogical to me James...



One cannot paint nothing.

If a value was anything more than zero, then it may be again divided.

Infinity does not exist.


By the way JB... black is not a color...

Yes I know.

light viewed through a prism segregates wavelengths and gives discernment of the various colors included in white light. Yet, a prism appears clear in its translucence.

The rainbow in the sky after a rain is what then?

different colored dust in array?

I was taught that red appears red because light reflected as red is the absence of red in the object being seen as red. that the light not absorbed by the object is the wavelength of the light not absorbed and reflected away from the object, thus appearing red.

amusing, infinitely.

Yes it is intuitively illogical.

But formal mathematics is not based on intuition.

There are a couple of things to realize here. First off, this is calculus and calculus uses the concept of the limit.

The answers are actually in a full understanding of the meaning of a limit. This goes back to the Zeno Paradoxes of motion that you had mentioned at one time. Mathematicians claim that calculus solves Zeno's Paradoxes, but it really doesn't and the reason it doesn't can be found in the formal definition of the calculus limit.

But mathematicians refuse to acknowledge this. They worship the Calculus Limit like as if it is a God.

And you might be surprised to know that very few mathematicians actually understand what it means. They just know how to crunch numbers through it. I once had a calculus profess who tried to explain the calculus limit to the class. His explanation was actually wrong thus showing that he didn't not truly understand it himself. He then confessed with some embarrassment that it's a very difficult concept to understand and that probably on four mathematician have truly understood it in all of history (his words). Obviously he was not one of the four.

I sat there think that perhaps I am one of the four then because I certainly do understand Karl Weierstrass's definition. He was the man who created the formal definition of the limit. A definition that I spend many years studying, and it took me many years before I truly understood the ontological meaning of it. I'm happy to say that I do now.

Fortunately for scientists and engineers this level of understanding is not necessary to use the limit or calculus. You can crunch numbers and have absolutely no clue why it actually works. I understand why it works, and what it means, and what it doesn't mean. It does not answer Zeno's paradoxes, that's actually a misconception that the mathematical community holds that simply isn't true.

The calculus limit does not address Zeno's paradoxes of motion. It simply allows for the calculation of coordinates under the assumption that things are a continuum. But the bottom line is that the calculus limit does not demand that things are a continuum neither does it prove or even suggest that they are. That's just not what the definition of the limit is saying. It doesn't solve Zeno's paradoxes of motion. That widely-held notion is simply incorrect.

Jeanniebean,

The notion of black come up because you brought up the concept of 'nothing'. Black is considered to be 'nothing' by some people. Almost like vacuum is considered to be 'nothing' by many people.

It is funny that zero and infinity have much in common. Talk about one and the other one always pops up. Like Michael said, divide any quantity by infinity and you come up with nothing. However, in formal mathematics these intuitive notions don't always hold true.

But maybe they will after I write my book.

Infinity in mixing colors

It was a difficult thing for me to understand that black was the absence of color being an artist, as it appeared to me that white was the absence of color.

But once you learn color theory you learn that color is simply reflected light and pigments are things that absorb and reflect light.

The pigment that reflects blue absorbs all the colored light rays except blue, which it reflects, causing the appearance of blue.

There are basically only three colors, red, yellow and blue.

All the rest of the colors you see are mixtures of these three colors.

When I teach color mixing classes, I teach my students how to mix the secondary colors (Orange, green, violet) and how to mix the three primary colors to get black.

Once you understand how pigments reflect and absorb light, you will have no problem mixing or adjusting any color, but it is very difficult to get this point across to students.

I had actually painted for 15 years before I realized this and learned what was going on. Up until then, it was a guessing game on getting the right color and shade.


Where I found infinity in mixing colors was in mixing compliments.

Mixing red and green.. you begin to get a duller green when mixed with red. More red and you approach the crossing point between the mixture being greenish or reddish.

That crossing point seems to be a point like infinity. You look at it and try to decide if it is greenish or reddish.

The color would look like brown, but is it greenish brown or reddish brown? Finding the point that is completely neutral, not reddish or greenish, is like looking for infinity.

JB

What about matter and anti-matter?

I have heard that when anti-matter meets matter, they destroy each other.

If this is true, what happens and where do they go?
