Apple co-founder Steve Wozniak has launched a school to teach computer science and technology-related skills. Wozniak last week announced creation of what is being called an online university, known as Woz U. In the beginning, Woz U will only offer classes through electronic devices connected to computers. Later, the school plans to open up classrooms in more than 30 cities so students can attend in person. Steve Wozniak founded Apple Computer, with Steve Jobs, in 1976.
