Chirp

*chirps*

I just thought I should meep or chirp to say I'm not completely dead. Just busy with differential equations and partial fractions and isoclines and all that stuff - since I'm going to take a test as part of moving (if however slowly) towards my shiny papers.

Yes, I should have known this about... ten years ago. But that time has already passed.

Also, I suppose there have been other things going on, it's just that when I'm doing various other things, I don't find the time to report on here, and so when I do go back and say "hey, it's awfully empty in here", there has been so much time since the things actually happened that I can't really sum them up :)

So... meep! Are there any other meeping critters around? Or perhaps some chirping ones, or even shiny crows?

Meep :)

*grins* If you're still having fun with series, try sticking complex numbers into some of them and see the stuff you get. There are some neat and surprising identities! Also, any convergent Taylor series for real numbers will also be an analytic complex function, conveniently.

Complex numbers are actually much more well-behaved than real ones, in this matter... if a complex function is differentiable, then it's differentiable to all orders, and has a series expansion to boot. Those things don't always go together for real functions. *shuts up now*

The problem in question is thinking "I'm stuck on this research problem involving brackets, so I'll go read more about Lie groups or differential geometry or topology until it all makes sense" where it might already be the case that I know everything I need to know to solve the problem. :(
