Corrected entry: Charlie Epps is discussing the Riemann Hypothesis, and its relation to very large prime numbers. In the graphics shown on the screen to depict what he is talking about, one of the large numbers shown has "10" for its final two digits. This cannot be a prime number.
Corrected entry: Charlie says the disease is a Pandemic Flu, to which Terry replies "The Spanish Flu" and goes off on a monologue about that illness. Pandemic is not the name of the Spanish Flu, pandemic means that it's an illness that infects both humans and animals. There have been several pandemic flus across history.
Correction: Terry mentions the Spanish Flu as an example of a pandemic, rather than saying it's the only one. By the way, the definition of the word 'pandemic' is: "Epidemic over a wide geographic area and affecting a large proportion of the population." It has nothing to do with what the disease infects.

Correction: At the zoomed in shot, it appears to be a 10, but something is cut off to make it look like a zero. At a zoom out of this shot, the block reads 719, a prime number.
