Charlie assists Don on a serial rapist case by calculating a "hot zone", an area where the rapist is most likely to live. Don is removed from the case after Charlie's formula fails to turn up any leads but later a comment from their father then leads Charlie to change the equation to calculate two points of origin, instead of one, leading to a new suspect. Anthony Heald guest stars.

Mathematics used: Geographic profiling, probability theory, 11-dimensional supergravity theory and projectile motion

2| 2| "Uncertainty Principle"| Davis Guggenheim| Nicolas Falacci & Cheryl Heuton| January 28, 2005 (2005-01-28)| 104| 15.46[2]

Charlie successfully predicts the time and place of a bank robbery using what he says are elements of Heisenberg's uncertainty principle, but when the planned arrest goes bad, he retreats into the math problem P vs. NP.

Mathematics used: P vs. NP and Heisenberg's uncertainty principle

3| 3| "Vector"| David Von Ancken| Jeff Vlaming| February 4, 2005 (2005-02-04)| 103| 11.55[3]

A deadly strain of influenza is spreading through Los Angeles, killing many people. Don investigates whether the strain was released deliberately, and Charlie tries to calculate the origin and likely spread of the virus. Guest stars include CCH Pounder, J.K. Simmons, and Rainn Wilson.

Mathematics used: Patient Zero, Viral vector, Vector and SIR model

4| 4| "Structural Corruption"| Tim Matheson| Liz Friedman| February 11, 2005 (2005-02-11)| 105| 10.68[4]

An engineering student dies by what is ruled a suicide, but Charlie suspects foul play. Don disagrees, but he agrees to help Charlie investigate whether the student was murdered because of his research into a building's structural integrity. Alyson Reed, Douglas Sills, and David Hunt guest star.

The Hyatt Regency walkway collapsed in 1981 as did the Hartford Civic Center in 1978.

The episode concludes with Don Eppes saying that Occam's razor says "that the simplest answer is usually the right one."

Mathematics used: Pendulum and Foucault pendulum

5| 5| "Prime Suspect"| Lesli Linka Glatter| Doris Egan| February 18, 2005 (2005-02-18)| 106| 10.49[5]

A young girl is kidnapped, but her parents refuse to cooperate with Don's investigation. The girl's father (Neil Patrick Harris) is an innovative mathematician, and the kidnapping may be related to his work on the Riemann hypothesis.

Mathematics used: Cryptography, prime numbers, Riemann hypothesis and Riemann zeta function

6| 6| "Sabotage"| Lou Antonio| Liz Friedman| February 25, 2005 (2005-02-25)| 102| 11.46[6]

Don is investigating a series of train accidents which are recreations of previous wrecks. The saboteur leaves a note composed entirely of numbers. Keith Szarabajka guest stars.

7| 7| "Counterfeit Reality"| Alex Zakrzewski| Andrew Dettman| March 11, 2005 (2005-03-11)| 107| 10.55[7]

A strange series of robberies leads Don into a case involving counterfeit money, kidnapping and murder. Don is assisted by Secret Service agent Kim Hall (Sarah Wayne Callies) while Charlie uses math to analyze fake bank notes and track their spread.

Mathematics used: Guilloché pattern and wavelet analysis

8| 8| "Identity Crisis"| Martha Mitchell| Wendy West| April 1, 2005 (2005-04-01)| 108| 10.00[8]

A new murder with disturbing similarities to an old case leads Don to question whether he put the right man in jail. While Don tries to find the connection between the two cases, he asks Charlie to look for mistakes or flaws in the first case. Luis Antonio Ramos, Dominic Fumusa, Marek Probosz and Molly Hagan are among the guest stars.

Mathematics used: Poker, geometric progression – paper folding, pyramid scheme, fingerprint and Schrödinger's cat

Don is investigating a series of sniper killings, and Charlie is searching for an underlying pattern to the attacks. What appears to be bad data can't be eliminated from the analysis, because it fits the only pattern he can find. Lou Diamond Phillips guest stars as FBI sniper and tracker Agent Ian Edgerton.

Mathematics used: Projectile motion, Tipping point, regression toward the mean and exponential growth
