Im Back (I think)

26 Jul 2016

For the past 5 months I've been taking a break from electronics and revisiting my roots in mathematics.  In particular, Ive been studying differential equations starting from my undergrad level to as much information as I can find.  I know computers can solve many of these DEs, but Ive been learning how to solve each type by hand.

 

I've known DEs for 15 years, but never really went in depth like I wanted.  The numerical methods in particular are of great interest.

 

Interestingly, MIT now puts many classes online.  So any of us can attend MIT as if sitting in the classroom.

 

One thing to note, just watching the videos doesnt do much, you MUST also do the homeworks they provide to prove you know the material.

 

Of course a good test of understanding is to try to interpret the theory of relativity, which is a set of DEs.

 

I still need to do my review for my Pi3.  it didnt work at first but I got it up and running, will know that out next week!

    Here we go Dubbie. Not exactly a differential equation but this is the Standard Model Lagrangian which describes the dynamics of every particle and their interaction. I solved it for W only to find that…

    42 was a nod to a radio programme, from years ago, scripted by someone called Adams. I misunderstood your post and thought you were saying 'infinity =' rather than '(the sum to) infinity ='. My fault for…

    Hi Joey, I had extensive DE exposure back in school, but I have to be honest, I have rarely used it in my career. But if you enjoy playing with equations, try using DE in Maxwell's Equations. I have been…

    I like ODEs too, Laplace transform, stability analysis and all that good stuff.

    Cool, keep in mind that learning the mechanics of solving them and applying them are way different.  Nearly anyone with an engineering degree has taken DE classes, and nearly all of the people I have met dont really understand what they are for or how/when to apply them.

     

    My goal is to apply them to more situations in my life, at work and in my hobbies.  That is how one can test truly understanding such things.

    Gravity.  Quadcopters, AI, unsolved problems in mathematics.

    Data analysis.

    Always good to solve some Riccati equation at the party.

    Here is one for you (don't use Matlab):

    When I did go to parties, I instead lifted weights and picked up chicks.  Most never knew I was into math.

    Ill get to it, I hope this is not some attempt to make me prove myself.  I have no inclination to do so.  But if its just for fun, Ill get around to it.  Im being forced to learn java spring, gradle, and groovy right now at work for the next 6 months.  I have years in .Net chaps my hide they switched.
