• 05:30 How do you get a message from one place to another? How to go faster, farther, accurate?
  • Construct a universal theory of communication that could allow perfect communication

  • His master's thesis (written at the age of 21) is considered the most important master's thesis of all time.

  • Compress your information. Eliminate the redundancy. Just send what you can't predict. Is there a minimum size, a minimum number of bits that I can shrink my information to and not lose anything essential?
    • The entropy is the absolute minimum size you can compress your message without any loss.
    • The channel has physical limitations, and then there's always noise. Can I calculate for any channel a speed limit beyond which you know things are gonna fall apart? An information speed limit like the speed of light.
  • Use mathematics to eliminate noise
