Saying that, when others such as myself raised the same point, underlines the "secret math cult" arrogancy. You are totally proving our point.

Besides, this thread is titled "admit your brain lock". What the fuck are you doing, we are discussing honestly about issues we are having understanding stuff and you come here to ridicule us for that.


--- Quote ---There really is a reason to use different versions of letters in formulas. For example, \$v\$ can represent velocity while \$V\$ can represent volume, and both can appear in the same formula.

Nice idea, but this shows how little you have actually worked with. The idea of fixed assignments of <100 symbols is completely dead. v and V can represent a lot of other things besides velocity and volume, and notoriously E can and WILL represent both energy and voltage, both of which often appear within the same formulae (also, W can represent energy (often change in energy, why won't you ever say dE for consistency?), U and V voltage - so much for "volume"). This is a total mess. Improvement starts from accepting this fact and not expecting fixed symbols to work.

The only real way to deal with this mess is to choose best suitable symbols for the job, and always explain the symbols used. Come one, if you have a  formula with 10 variables, it's ten lines of text to explain them all. There is no excuse not to do this. But no, you guys here come to defend this mess and outright refuse to admit its existence. You think math and its notation is elegant and consistent, in reality this couldn't be further from the truth.

This discussion has made me more certain than ever that what we are indeed seeing is 100% deliberate obfuscation.

I'm not suggesting of implementing modern-day programming practices into math directly, but it is quite revealing to think how most of mathematical work would never pass any code review process.

If you have the same issue as Zero999 (not registering the difference between symbols), then I'm afraid the problem is at your end (even though it isn't your fault). It is similar for a color blind not being able to work in a paint shop. And I'm not trying to make fun here. Somebody I know works at a hardware store but due to color blindness, this person can't work at the paint department. However the person can't tell the world to discard every color a color blind person can't distinguish.

Yes, I know. I really meant "in a minority" but didn't manage to write that.

Yes, of course, but I didn't say anything about fixed assignments. I said the symbols can represent certain things, as an example, not that they always do. Of course I know on an electrical forum that V can represent voltage, and that E can too. If you want to use E for voltage and also for energy in the same formula, well that would be a mess. What would you do in that situation?

Yes, and in every professional text I have ever read, this is what is done. Do you see places where it is not the case?

It would only be obfuscation if people were choosing unconventional symbols for things, and also not explaining what they are being used for.

--- Quote from: Zero999 on April 05, 2024, 05:41:24 pm ---Exactly people think differently.

When I see something which looks vaguely like a letter, I just see the letter. Subtle differences between glyphs such as ω and w are discarded. I can clearly see the difference between T and τ, but I remember them as the same letter. This is even worse when I'm writing it down, since my hand doesn't do as my brain tells it. I often miswrite words I know how to spell. The weird non-English letters are even worse.

But I do think learning and practice can help. Minds are not fixed, they can change.

For instance learning and using the different names for different things, such as \$T\$ "tee" and \$\tau\$ "tau". If you think "tau", it could help to avoid writing a "tee". Similarly for \$\omega\$ "omega" and \$w\$ "double-u". Different names, therefore different things. (Though I admit, in this case, \$\omega\$ and \$w\$ do look very similar. That is unfortunate.)

I agree about learning like that and can cope to some degree, especially with print, but stood no chance with handwriting. I still don't see the point in make it more difficult than necessary.

Precisely.

It is a great shame for someone to have their ambitions dashed when they find their chosen career depends on normal colour vision. I've heard of aspiring pilots discovering that rather late in the day. I feel for them - but if they railed against the "colour elite" I would thing they were twats.
