Picard and the Enterprise are urgently called back to Earth to see the results of an archaeological dig that reveals aliens may have visited the planet in the 19th century. Among the many relics they have found is one that is totally out of place - Commander Data's head. Data confirms that it is his own head and not that of his brother Lore. He seems completely at ease with the find, which is not the case with the rest of the crew. On the planet, Data encounters a temporal vortex and he suddenly finds himself transported to 19th century San Francisco where he meets none other than Guinan. Written by garykmcd

The title is in reference to British astrophysicist Arthur Stanley Eddington's 1927 concept that time is run as a "one-way direction" or "asymmetry" and that its direction can be determined by studying the organization of atoms, molecules, and bodies. See more »

Lt. Commander Data: It is possible, sir, that the events leading to my death will not occur for years, even centuries.
Captain Jean-Luc Picard: I hope that's true, Mr. Data. Nevertheless, this investigation began with your death. I'm simply trying to see that it doesn't end that way.
Lt. Commander Data: I appreciate your concern, Captain. But, to employ an aphorism, one cannot cheat fate.
Captain Jean-Luc Picard: "Cheat fate"?

Captain Jean-Luc Picard: Perhaps we can't, Mr. Data. But at least we can give it a try.

Good temporal episode
19 April 2016 | by (United States) – See all my reviews

After the silly, dull "The Inner Light", TNG returns to form with this excellent, important two-parter.

When Data's head is found in a long-abandoned mine or Earth, the crew investigates, which leads to Data being transported to the 19th century.

It's interesting that even though Data has no grasp of contractions, he's able to speak French, which has mandatory contractions.

It's also nice that Guinan is finally given something to do. This episode starts to elaborate on the close relationship between her and Picard, but there are still many unanswered questions.
