I saw this story a few days ago, and it was one of those rare science stories which made me go: 'mmm, that's interesting...'. From the perspective of: that's why I can rarely catch that fly In a nutshell:
This sounds like something out Frederik Pohl's MAN PLUS. Astronaut Roger Torroway is converted into a cyborg able to live on the surface of Mars, the vanguard of a colony project. The first cyborg died from sensory overload. So Torroway is given a computer to mediate the flood of data from his enhanced sensorium. When something is knocked over in the lab, he catches only those items that would break upon hitting the floor. He literally did not see the other items, and his time sense was speeded up during the catch. Torroway's time sense is later slowed (by varying his perception of the environment) to make the months-long trip to Mars pass in a subjective instant.
Yes, flies are in bullet time all the time. must be very boring for them when not much is happening...
