1	1	"Pilot"	Mick Jackson	Nicolas Falacci & Cheryl Heuton	January 23, 2005	101	24.92[1]
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. 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	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	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. Mathematics used: Patient Zero, Viral vector, Vector and SIR model
4	4	"Structural Corruption"	Tim Matheson	Liz Friedman	February 11, 2005	105	10.68[4]
An engineering student commits 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. Mathematics used: Pendulum and Foucault pendulum
5	5	"Prime Suspect"	Lesli Linka Glatter	Doris Egan	February 18, 2005	106	10.49[5]
A young girl is kidnapped, but her parents refuse to cooperate with Don's investigation. The girl's father is a 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	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. Mathematics used: Kasiski examination, Cryptography, Fibonacci sequence, golden ratio and Beale ciphers
7	7	"Counterfeit Reality"	Alex Zakrzewski	Andrew Dettman	March 11, 2005	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 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	108	9.99[8]
A new case 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. Mathematics used: Poker, geometric progression – paper folding, pyramid scheme, fingerprint and Schrödinger's cat
9	9	"Sniper Zero"	J. Miller Tobin	Ken Sanzel	April 15, 2005	109	10.54[9]
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. Mathematics used: Projectile motion, Tipping point, regression toward the mean and exponential growth
10	10	"Dirty Bomb"	Paris Barclay	Andrew Dettman	April 22, 2005	110	11.50[10]
A truck carrying radioactive waste disappears, and Don figures that a dirty bomb will be set off in downtown Los Angeles. When three suspects are caught but refuse to turn on each other, Charlie must try to convince one of them to give up the others and also the location of the waste. Mathematics used: Prisoner's dilemma and radioactive decay
11	11	"Sacrifice"	Paul Holahan	Ken Sanzel	April 29, 2005	111	10.80[11]
A researcher is murdered in his home, and Charlie must reconstruct data erased from his computer while Don investigates possible suspects. Final appearance of: Sabrina Lloyd as Terry Lake Mathematics used: Sabermetrics and econometrics
