Some of the math in my posts is wrong

Is wrong or are wrong? 

So I try to work on math problems related to ideas I have

I write the math problem down and try to solve it

As I make progress I change my posts with these problems over time

Sometimes I leave the post unsolved or solved incorrectly or with incomplete and possibly wrong attempts at solving the problems

Sometimes the solutions are correct

Some of my posts most likely have wrong information that I just have not got around to correcting for years

I have to be willing to try different things and possibly put down wrong information to be able to get to the right answer

When you solve a problem in  textbook you should try to do it on your own writing steps on paper and then check the back of the book to see if it is write.  You have to be willing to put down many wrong answers to learn how to get write answers.  Later you can check the back of the book.  Most people do not post all their mistakes practicing for the public to see but only show their attempt where they finally found the steps to get the write answer.  My blog is different in at least two ways.  First in real life science there is no back of the book one can only make a model and then test it to see under what circumstances it works with real life experiments, some models are good at predicting things under some circumstances but not others.  Second, I am willing to show the potential errors I make while I am doing work to practice towards solving a problem,  I kind of use this blog like a public notebook where I brainstorm ideas and then try to practice solving them.  I want something publicly available that I can find where I lift up with my work to complete it later because when I practice writing problems on paper I might lose the paper or it might get damaged, also because there is a public record I can get the ideas there for other people to think about and maybe even if I set up a problem and solve it wrong someone else will look at it and get the correct solution and society will advance more than if I kept it there by myself until I got it right.  Sometimes when I think something is wrong I change it, but a lot of this material is archived with early mistakes on web.archive.org

Sometimes I might leave posts up that I abandoned because it shows a starting place for the thinking, sometimes I might leave the old stuff but start on a whole new post at a different link that is better done.  Sometimes I might plan to do so but never get around to it.

So do not assume the math here is right check it yourself.  It is put here to think about the problems which might lead to the correct answer later down the road but not to necessarily show the correct answer.
