management, preparation «f tax returns, banking, hospital administration, insurance,
publishing, to complex scientific and engineering applications such as weather
forecasting, space shuttle launching, oil and natural gas exploration, design of complex
structures like aircrafts, ships, bridges, sky-rise buildings, etc. With so many applications
