Space may be the final frontier, but it’s been studied since the dawn of civilization. And while early man could only stargaze with unaided eyes, astronomers today use extremely sophisticated equipment to examine the universe.

Finding the most effective way to produce a product or service is the job of an Industrial Engineer. They are the bridge between management goals and operational performance. They solve problems by combining production resources: people, machines, materials, information and energy. They use mathematical techniques, expert computer systems, cost analysis, financial planning, quality control and complex distribution plans to improve profits view more

Medical appliance technicians combine a knowledge of human anatomy with math and power tools to create artificial limbs and braces. They work as assistants to orthotists and prosthetists, medical experts who use specially-designed devices to help patients overcome a physical disability. The technicians read prescriptions and detailed information about what the patient needs. They often work from a cast or impression of the limb as a pattern, taking careful measurements with precision instruments view more
