Last week, in Part 1 of Neil deGrasse Tyson’s interview with whistleblower Edward Snowden – via robotic telepresence from Moscow – much of the conversation focused on the U.S. Constitution and the 4th Amendment.
This week, the two self-defined geeks dive into some serious math as Edward tells Neil how cryptography works, from asymmetric encryption to secret sharing schemes and n-dimensional matrices.
But before you decide that Part 2 gets too technical for you, think again: the Cold War maybe be over, but in a world where a drone strike could be targeted using metadata, understanding how that data is derived and weaponized is just as important today as understanding the potential impact of nuclear fallout was last century.
And besides… then you’d miss out on Edward asking Neil whether cosmic background radiation, pulsars or other astronomical objects could be used to generate perfectly random numbers that could be used to generate perfect seed keys to be used in encryption, and the fascinating conversation that ensues.
You’ll have to decide that for yourself, but we think so.
