Such confusion. 1/3 does not have a mantissa. The IEEE754 floating-point representation of 1/3 has a mantissa (but so does the floating-point representation of 0,1,2, etc.!).Um... I didn’t say that? I said the repeating mantissa is *one* unit to NOT be truncated, or you lose its definitiom as 1/3. Of course it can be written in decimal form.
You're correct that, in base-10, we cannot truncate the decimal expansion of 1/3. But this is also true of Pi -- truncating the decimal expansion of Pi gives you a different number. So, what's the difference?!
Same with Pi.The moment you truncate it, you’ve jeopardized its identity as a repeating decimal and now it is not representing 1/3 properly.
I'll have what she's having. I'm going to give you the benefit of the doubt and assume you were high AF when you wrote this, lol.Point missed. We don’t divide 1/3 there! We MULTIPLY the man-made measurement algorithm 1/3 by the value, notice? 33 gallons, what is 1/3 of it? 1 TIMES 33 divide by 11. That is 3. And proper reasoning. :—)
It's hilarious to me how you insist that 80,000 Ph.D.'s will disagree with half (one-third?) of the things I say, while claiming with a straight face that 1/3 is not a number.1/3 is not a number. It’s a numeric dividing measurement process designed to create another. 1/3 of what? A fractional expression is a utilitarian process to make measuring easier, so we can stay in a given unit, and don’t have to use whole numbers for every measurement and change units (1.5 feet instead of 18 inches). That’s why we invented them.
I fully and genuinely believe in your freedom to choose not to call rational numbers "numbers". I, however, will continue to fruitfully recognize number sets of all color and creed. #rationallivesmatterSee above. Fractions are NOT numbers, they are two-number processes: their purpose is to yield another number or process for convenient measurement purposes... You can say 1.5 feet and remain in feet units instead of having to switch to another label expressed as a number (e.g., 18 inches). Mathematics goes beyond “REAL” in its semantic f*ckery, I tell you.
"The TRUE expression of numbers" -- spoken like a TRUE zealot! Analog computers are the devil's work!I only see base 1 and base 2 as the TRUE expression of numbers, as a computer does, which is an overlap of logic states and quantity metrics, and where the divide between quantitative value and spatial representation effectively disappears by seeing them as amalgamations of logic states.
Sigh. 22/7 and Pi are different numbers. You claim that 22/7 has a dimmer switch, but that dimmer switch somehow disappears when we write it in base-7. "Oh, but base-7 is useless". No, your argument is useless. Anything you can write in base-1 or base-2, I can write in base-7 and use less paper while doing it.Pi in this elementary definition is still a “resolving” process, NOT a number. It has a dimmer switch at its basest “representation”. Base-7 is as useless as understanding it as calling it a day with “π”
"Fractional arithmetic expressions". You don't seem to realize that we can write 1, 2, etc. as fractional arithmetic expressions. In particular, we can write them as non-terminating fractional arithmetic expressions and they describe the same number.Again, they are NOT numbers. They are fractional arithmetic expressions invented for measurement conveniences using the integers with operator concatenations.
I'm curious, do you believe that negative values are numbers? Is -5 a number?
So, you're saying that my conception of a Bb maj7 chord refers to a specific set of waves borne from vibrating strings? Which set exactly?To write the chord out using 2D glyphs is dimensional, #1. No awareness of the chord without such.
Secondly, no chord without 3D objects (strings) making it. Thirdly, the wave itself is dimensional.
You've probably never studied linear algebra, and that's fine. But a vector space is an abstract space with no geometrical objects. There are no lines or points in a vector space. In order to induce a geometry on a vector space, you need additional structure, namely, a compatible inner product. Using this inner product, you can define the notions of line, point, angle, etc.Fallacious notion! Euclid‘s definitions are entirely geometric first, as you learned them first! they were taught drawing on a 2D chalkboard! You can’t even discuss vectors and spaces (spatial any one??) until you discuss lines and points. And vectors are also written as 2D arrows and arrays!
Vector spaces are more fundamental than geometries. In physics classes, teachers use arrows on graphs to represent vectors in \( \mathbb{R}^2 \) or \( \mathbb{R}^3 \), but this is purely didactic in purpose, a way to help students get a concrete sense of the physics involved. In math classes, a vector is just an element of a vector space. It has no shape. It doesn't even have coordinates until we pick a basis set. But the choice of basis is arbitrary. Just as with numbers and bases, a vector is independent of any basis. Yet, somehow, I am able to conceive of such a thing without any reference to spatiality.
