Is change possible?

[Farid7]

Hello everyone,

I would like to share something about change. The "Y" is a variable for anything in general.

"If something different than Y is not Y. Then Y cannot become something different, because then something different is Y. Thus Y cannot change."

Change requires time.
God, being Eternal, is outside and is unaffected by, time.

In a world where Y is a variable for anything in general, then there is no such thing as something different than Y.

I meant that it is a variable like when X is a variable for a number in mathematics.

Take Y to be my weight. If my weight changes, Y is ... no longer my weight? Huh?

That sounds like Parmenides' notion that all reality is one being, and change is just an appearance not the reality of the one. Parmenides had an ontological commitment to monism. Spinoza did as well, but I can't remember if he ever argues that change is a mere appearance.

Good grief...

If something changes then it becomes something different. And this is the basis for a thread?

If Y stands for your car's speed (and it is non zero), then even if Y is constant, your car's position is constantly changing.

The more that Y changes, the more Y stays the same.

According to the first post, your weight cannot change.

Yes, true. But, according to the first post, your car's position cannot change.

Suppose Y is a lump of pure iron ( Fe.) It’s left outside exposed to the environment. After a while, it reacts with oxygen and water vapor and becomes rust (Fe2O3 ) Y has changed into a completely different substance.

This is why Y is called a variable -- because it isn't able to vary.

Iron consists of 4 isotopes each with different atomic weights. separate each are different substances that combine to form iron. And because of the 4 isotopes iron can vary.

"If something different than Y is not Y. Then Y cannot become something different, because then something different is Y. Thus Y cannot change."

Restated for clarity:

If <something different than Y> is not <Y>, then <Y> cannot become <something different than Y>, because then <something different than Y> is <Y>. Therefore Y cannot change.​

Each isotope of iron is iron. Any isotopic mixture of iron is also iron. What makes iron iron is the electron configuration.

One of the isotopes 56fe has different ranges depending on its location around earth. The third lowest amount of the 4 isotopes that constitutes iron, if I'm not mistaken 58fe is the least abundant isotope.

Dissolved δ56Fe ranges from −0.13 to +0.21 ± 0.08‰ in the Southeastern Atlantic (8), from −1.35 ± 0.03‰ to +0.80 ± 0.06‰ in the North Atlantic (4, 11), and from −0.03 ± 0.07‰ to +0.58 ± 0.08‰ in the Equatorial Pacific

@Farid7,

Welcome to CF. Please have a seat in The Lounge. We should have your question ironed out in no time.

 

[BeyondET]

You guys are really ironing out this thread.

Bringing up some telluric iron,

This is getting off-topic. It's my understanding that Fe-56 is the most abundant iron isotope. In living organisms (marine invertebrates and arthropods excepted) it's the oxygen carrier found in hemoglobin. It's also in myoglobin and is stored in liver cells.

I could look it up, but this is almost certainly wrong. Fe56 is certainly the most abundant iron isotope. Fe58 should be the second most abundant of the iron isotopes. Fe56-59 are stable and there is a trace of Fe60 (million year half life) replenished from space dust.

Generally speaking nuclei are more bound if either the proton number or neutron number is even due to quantum mechanical pairing. Iron has 26 protons, so the even numbered isotopes of iron are more stable. The same principle leads to even-even isotopes being common in production. (This is the same reason iron is more common than cobalt or manganese
