 Hi, I'm Zorsch Echtmann. I'm a mathematician by education. I'm a computer programmer and financial specialist professionally and I consider myself to be a teacher by inspiration. I was born and educated in the Soviet Union a long time ago. I graduated from Moscow University from the School of Mathematics, which at the time was probably one of the best in the world. I would also like to mention my high school education because I had a brilliant teacher who directed me towards mathematics and that included actually mathematical olympics, olympiads, which we had at the time in the Soviet Union, which I won a few prizes at the time. Then I was working within the computer industry as a specialist, the programmer primarily. Working for the Department of Statistics. At the age of 30 years old in 1979, I was my family immigrated to the United States and live in New York since. I was working for primarily financial companies. I was working for the company which provides financial data for all other financial companies, probably one of the best in this area. Then I was working for the largest in the world asset management company where I was responsible for all the data coming into their computer database. Well, after retirement, I was thinking about what exactly I can devote my efforts to and I was quite disappointed actually with the level of math education in many schools, as far as I could judge actually. I have decided to dedicate my efforts towards improving this math education in high school, primarily in high school. So I decided to create a few lectures, put it maybe on the Internet or something, and address certain students who would like to basically watch these lectures. Well, at that time after LERNCIS approached me with their offer to participate in their efforts to promote basically education in general and mathematical education in particular, I decided that this would be a perfect match between whatever information I would like to share, the knowledge which I would like to share, with abilities of the company like LERNCIS to distribute this information. It's like the relationship between the writer and the publisher, I believe. So I think it would be very beneficial for all the parties involved. For me, because it actually stimulates my creativity, hopefully for LERNCIS as well as a publishing house or an analogy of Internet analogy of publishing house, and hopefully for the students who will be using whatever information I can share with just to improve their logic, their analytical thinking, their creativity. Because math is actually considered at least by many, including myself, as a perfect tool to create your qualities of logic, analytical thinking, your creativity, etc. So I hope it will be very helpful for general audience, especially among home schoolers who might actually consider the Internet as the most important source of their knowledge. So I hope this cooperation with LERNCIS will be a success. Thank you very much.
