About me:

My History ---------- I attended Oregon State U. and majored 3 years in Electrical Engineering. Then I switched to a Math major for my final years and graduated with a B.S. in Math. My first job was with Lockheed Aircraft Co. building the SR-71 (Black Bird). One assignment had me designing the pilot's suit. It was to be 1/4" thick consisting of 5 materials and required to drop the outside temperature from its high to 98 degrees next to the pilot's body temperature. A great math problem! Another job was at Memorex Corp. designing a "Matched Filter" for a 14" disc drive. This electrical filter was to make a pulse more symmetric and thinner. The more symmetric and thinner a pulse, would help minimize the "Pattern-Induced-BitShift" (PIB). Heavy math problem! (Main LaPlace transform equation took me 22 pages of hand written notes to derive the necessary equations. Oh, those little minus signs kept giving me trouble!) Next job was at Lockheed Missiles & Space Co. Here I had different assignments. One assignment had me analyzing, what is called Digital Signal Processing (DSP), a plume from a space craft to try and label it as a "Friend or Foe". If its a Friend no problem, but a Foe may require action to be taken for it may shoot you down. This job required understanding the Fourier Transform. (FFT algorithm was being used. That was a BIG math mistake. I switched to 10 other algorithms and partially solved the problem.) For more, see my SpectrumSolvers v. 6 app... fortranCalculus.info . After a lay-off in 1991, I started writing my math textbook/casebook. 26 years later the book is done plus a website, 4 apps developed, & front-end for a compiler I developed in order to show a new computer language that makes solving math problems very easy. This 'new' language takes a 'automobile' level computer to a 'airplane' level computer. Design solution times drop by (around) 95%; i.e. what took 20 months is now done in less than 1 month and the solution is optimal. ---
