• Introduction; 1. Radical contingency and the materializations of technology; 2. From stone to radiation: the depth and speed of technical embodiments; 3. The technicity of time: 1.00 oscillations/sec to 9,192,631,770 Hz; 4. Infrastructure and individuation: speed and delay in Stelarc's Ping Body'; 5. Losing time at the PlayStation: realtime and the 'whatever' body; 6. Life, collectives and the pre-vital technicity of biotechnology Conclusion.

"Mackenzie seeks to pinpoint the relationship between conceptions of technology and technology as a physical and temporal process. Although Mackenzie's philosophical exploration of transductions of the living and nonliving addresses broad subject matter, the underlying concepts are analyzed with precision." Summing Up: Recommended.
