Gilbert Strang

Yes. I bought a book , finally.
It's a classical Gilbert Strang Linear Algebra and Its Applications which is not at all in the list of wished book last month. The decision is made because to read Galier Geometric Methods and Application -- well actually for any applied mathematics -- you need to have a solid basic in Linear Algebra. That's why, finally I bought Gilbert Strang's book.
At the same time, I started to reread the Routledge Philosophy Guidebook to Kant and the Critique of Pure Reason book.
