Physics anyone?

[garethom]

To be fair phigure, I'm pretty physically major too. How much can you curl?

[unwind]

Unwind, which aspects of wonders of life did you have difficulty with? Life as an energy input process to temporarily impose otder against the natural tendency of the universe to slide towards disorder? Maybe we can try to help explain.

Well in the end I managed to get a pretty good understanding of most of it. It's the parts that got into the chemistry side of things, and about protons and ions etc. where I got lost a bit (never been very good with chemistry or physics at that scale), in particular where he explained that the acidity of the water in the lake is basically down to the difference in concentration of ions and protons. I've never been particularly clued up about things on that scale so it made it a bit difficult to understand. I found myself wondering why that difference in concentration of protons/ions causes acidity, and what it is about it that quality that causes it to corrode things?

I suppose it was more just me confusing myself even more by thinking further into a subject that I never quite understood in the first place, lol

Acidity is defined, essentially, as the concentration of hydrogen ions (H+) in a given solution. Water is H2O. However, it doesn't always exist as H2O. It occasionally reversibly breaks down into H+ and OH- ions (the confusion between ions and protons probably stems from the fact that a H+ ion is, in fact, a proton. Being a physicist, he probably decided to refer to H+ ions as protons while referring to the OH- ions as "ions"). Both H+ and OH-ions are very reactive. But because there are equal numbers in pure water, they effectively react with each other and mop each other up. When you have an imbalance of H+ and OH-, the solution becomes reactive because you have an excess of either H+ or OH- floating about. When there are excess H+ ions, we call a solution acidic. When there are excess OH- ions, it's considered basic (or caustic). Way back when, someone decided to make a scale based on the number of excess H+ ions in a solution. They decided that neutral water was in the middle (pH 7), a very strong acid was pH 1, and a very strong base was pH 14.

Both acidic and basic solutions corrode things because the H+ or OH- don't like to exist as charged ions. They prefer to combine with other things to form a neutral molecule. So an acidic solution will attack stuff that allows the free hydrogen ions to combine with other elements in such a way that the whole mixture becomes more neutral (and therefore more stable).

I can go into reactions a bit more but it starts getting a bit more complicated because it involves electron orbitals and their effect on stability. Let me know if you want me to do that.

I literally just walked out of my workshop...doing the "practical chemistries"

I just finished a bunch of new silicon molds - mixed + poured the 1st round of polyester resins...

I had to take advantage of this warm spell we have...It's been slowing me down.


Unmolding silicon is a bit like obstetrics - I have to do episiotomies and it's just generally difficult in a small way - like birthing little giant stones...

Here is some of my recent work - I sliced a piece of my thumb off yesterday.
I have given blood to - literally - everything I have made to date...

[lovelydivot]

The skull wasn't my idea - It was my little cousins
- But they turned out pretty cool so I made some stuff with them...

Here's a Dior skull...fancy




Don't worry Lace - I haven't forgotten about you - I have your address right here...

This is a thread about physics BM.
How the fark did you manage to start talking about your jewelery again?

Innit, can a mod delete/move the posts into their own thread?

[lovelydivot]

It was a chemistry connection...

I have no experience in physics beyond shaping metal on a molecular level...and a little practical chemistry


It does seem a bit of a a stretch in hindsight...

I don't need to be involved with every interesting thread...
Especially if my input is feeble.

I missed the hard science bus.

I apologize.

[Electric_Head]

Chemistry and Physics are 2 very different things.

Not that I mind your post anyway.
You have nice jewelery.

[lovelydivot]

I thought chemistry was really just molecular physics.

And thank you - Just some eye candy for the people.

[Electric_Head]

Valid point.
I've just never really seen physics from a molecular level.
Engineer thought patterns

physics studies the smaller side of things to the larger things like astronomy and throw in everything in between while we're at it. i mean, chemistry has it's similarties being built on physical laws but it focuses on the behavior of one set of systems in so much greater detail then physics does. tbh, i'm more interested in the basic principles that govern the components of our perceived reality. but you know, when it's all said and done it's all linked in one way or another and hard to focus on just one aspect of say chemistry..or physics. unless you're studying something like theoretical physics or genetics. but what's it all if you don't have a solid grasp on mathematics right

[Phigure]

exactly

because physics is really just applied math

one of the biggest anomalies maths scientists dont understand is how 4 + 20 = 420, but 20 + 4 = 24. Will we know the answer in our lifetime?

All about 4 + 30 = 430 m8 poppin molly
