  • Imagine a circle that contains all of human knowledge
  • By the time you finish elementary school, you know a little
  • By the time you finish high school, you know a bit more
  • With a bachelor's degree, you gain a specialty
  • A master's degree deepens that specialty
  • Reading research papers takes you to the edge of human knowledge
  • Once you're at the boundary, you focus
  • You push at the boundary for a few years
  • Until one day, the boundary gives way
  • And, that dent you've made is called a Ph.D.
  • Of course, the world looks different to you now
  • So, don't forget the bigger picture
  • A bipolar junction transistor consists of three regions of doped semiconductors. A small current in the base can be used to control a large r current flow ing between the emitter and collector.
  • a valence electron is an electron that is associated with an atom , and that can participate in the formation of a chem ical bond ; in a single covalent bond , bo th atoms in t he bond contribute one valence electron in order to form a shared pair
