6.002 IS ALL ABOUT …
• Electronic devices and circuits:Modeling → What makes a good model?Analysis → What does “it” do and how/why does “it” work?Design → What is a good design and how is one found?Applications → Signal processing
Energy processingInterfacing to the “real (analog) world”
• Managing complexity:Physical complexity … individual complexityDimensional complexity … group complexity
• A powerful language for lumped-parameter analysis and design
• Practical skills for UROP, internships, education, research …
