The Time Travel Mistake that can Secure Your Destiny

Small changes have a powerful impact over time

In Ray Bradbury’s A Sound of Thunder, Eckels hires Time Safari, Inc., to take him back to the Late Cretaceous to hunt a Tyrannosaurus Rex. When he faces his quarry, he loses all bravado and panics. He leaves the path, steps on a butterfly, and alters the present-day. Words are spelled differently. The other candidate won the election.

McCoy steps through the Guardian of Forever and stops Edith Keeler from being hit by a car. Keeler delays the US’s entry into World War II, Germany wins, and the Federation ceases to exist mid-sentence.

Marty McFly saves his father from getting hit by a car (different car) and almost erases himself from existence. Barry Allen saves his mother from getting killed when he was a child and… you get the picture.

It’s a trope of science fiction. Time travelers are always concerned about changing the present by making some small change in the past, but we never think that we can seriously change the future by making some small change today.

Should You Use Your Apple Watch in the Shower?

Is “just in case” worth the risk?

When the Apple Watch was first introduced, there was a lot of optimism about the new ways it would enable us to be productive. One of the common questions was whether you would be able to wear it in the shower to talk to Siri.

I understand the question. We can come up with some great ideas in the shower. This might be the only time we have to step back from a problem and think about it, and Siri gives us a way to capture those key insights.

If you really can’t go 10 minutes without talking to Siri, then yes. Yes, you can wear your Apple Watch (series 2 or later) in the shower. With some precautions, you won’t even break it.
