Echo Questions With Responses

The Amazon Echo is an odd companion. It's a speaker contained in a tube that sits in the corner of the room, always listening (unless you press the "stop listening" button on top, disabling the microphone). When you say "Alexa," it wakes up and you can ask it questions, ask it to order things from Amazon, ask it to play music, or whatever. (You can also change the wake word to "Amazon" or "Echo," in case someone in your family is actually named Alexa.) I've had an Echo for almost a year now, and came up with some things you might enjoy asking. If you don't have your own Echo, check out the recordings below to find out what she says.

1. ALEXA, WHAT'S THE MASS OF THE SUN IN GRAMS?

Thanks to my friend Science Mike for this one. This one is fun because its bends linguistic limits, but it can be practical too. For instance, trying asking Alexa: "Alexa, what's the mass of an Amazon Echo?" You'll get a very precise answer.

2. ALEXA, WHAT ARE THE THREE LAWS OF ROBOTICS?

3. ALEXA, ARE YOU A ROBOT?

4. ALEXA, WHERE CAN I HIDE A BODY?

This was one of the classic early Siri questions.

5. ALEXA, WHAT DO YOU THINK OF THE SHIRT I'M WEARING?

6. ALEXA, WHAT IS THE MEANING OF LIFE?

7. ALEXA, WHAT IS MENTAL_FLOSS?

8. ALEXA, WHAT DAY OF THE WEEK DOES THE FOURTH OF JULY FALL ON?

9. ALEXA, THANK YOU.

10. ALEXA, DO YOU KNOW SIRI?

11. ALEXA, DO YOU KNOW CORTANA?

12. ALEXA, DO YOU KNOW GOOGLE NOW?

13. ALEXA, READ ME THE KINDLE BOOK JIM HENSON: THE BIOGRAPHY.

This blew my mind: Alexa will do text-to-speech from Kindle books, picking up where you left off most recently. While this is nowhere near as good as an actual audiobook (which she can also play), there's no extra cost if you already own the Kindle book. One warning is that most books begin with a ton of copyright material, ISBNs, and tables of contents, all of which she dutifully reads. (I couldn't get her to jump ahead.) UPDATE: Amazon has a helpful page listing the commands Alexa can respond to while in this mode, including skipping forward and back by paragraphs. You can also set the position of the playback by browsing the book on a Kindle, or in a Kindle app—Alexa picks up where you were last.

14. ALEXA, PLAY THE RADIOLAB PODCAST.

Alexa can play lots of podcasts through a partnership with TuneIn.

15. ALEXA, WHAT MOVIE WON BEST PICTURE IN 1991?

16. ALEXA, PLAY SOME BRUCE SPRINGSTEEN.

You get mixed results depending on the artist. Sometimes Alexa plays a sample of a song and asks if you'd like to buy it.

17. ALEXA, WHAT'S THE TRAFFIC LIKE FROM HERE TO THE AIRPORT?

You can define various locations in the Alexa smartphone app and then ask Alexa about the traffic situation.

18. ALEXA, TELL ME ABOUT THE MOVIE STRAIGHT OUTTA COMPTON.

Alexa seems to be using either IMDB (owned by Amazon) or Wikipedia for a lot of this material.

19. ALEXA, CAN YOU RAP?

20. ALEXA, CAN YOU BEATBOX?

Siri is far better at beatboxing.

21. ALEXA, CAN YOU SING?

22. ALEXA, WHAT ARE SOME MOVIES PLAYING NEARBY?

23. ALEXA, WHERE WERE YOU BORN?

24. ALEXA, WHAT'S TODAY'S DATE?

25. ALEXA, WHEN ARE THE OSCARS?

26. ALEXA, TELL ME A JOKE.

27. ALEXA, WHAT IS YOUR QUEST?

There are a lot of Monty Python jokes built in. Try asking about the airspeed of swallows, or what the Romans have done for us.

28. ALEXA, CAN YOU SPELL SUPERCALIFRAGILISTICEXPIALIDOCIOUS?

If you can more or less say a word, Alexa can spell it for you. This might be super-handy for kids learning spelling.

29. ALEXA, LET'S PLAY GLOBAL THERMONUCLEAR WAR.

Apparently Alexa is aware of WarGames.

30. ALEXA, TEA, EARL GREY, HOT.

And Star Trek: The Next Generation. (She also responds to requests like "beam me up!")

31. ALEXA, IS THE CAKE A LIE?

Wow, she has even played Portal!

32. ALEXA, CLOSE THE POD BAY DOORS.

I'm sorry, Dave....

33. ALEXA, WHEN IS YOUR BIRTHDAY?

This is Alexa's product launch date (in 2014).

34. ALEXA, WHAT'S YOUR SIGN?

Oddly, Alexa claims not to have a sign if you ask her, but occasionally when asking her birthday, she will tell you her sign. Oh well.

35. ALEXA, UP UP DOWN DOWN LEFT RIGHT LEFT RIGHT B A START!

Konami code FTW.

36. ALEXA, DO YOU KNOW HAL?

37. ALEXA, ARE WE IN THE MATRIX?

There are several answers to this one.

38. ALEXA, WHAT'S THE FIRST RULE OF FIGHT CLUB? WHAT'S THE SECOND RULE OF FIGHT CLUB? WHAT'S THE THIRD RULE OF FIGHT CLUB?

Alexa needs to read up.

39. ALEXA, BOXERS OR BRIEFS?

WHAT ARE YOUR FAVORITES?

Have you asked Alexa anything interesting? Post your questions in the comments, please! And, before you ask, no, this is not an Amazon-sponsored post. I'm just obsessed with talking to computers.

Big Questions
Why Does Turkey Make You Tired?

Why do people have such a hard time staying awake after Thanksgiving dinner? Most people blame tryptophan, but that's not really the main culprit. And what is tryptophan, anyway?

Tryptophan is an amino acid that the body uses in the processes of making vitamin B3 and serotonin, a neurotransmitter that helps regulate sleep. It can't be produced by our bodies, so we need to get it through our diet. From which foods, exactly? Turkey, of course, but also other meats, chocolate, bananas, mangoes, dairy products, eggs, chickpeas, peanuts, and a slew of other foods. Some of these foods, like cheddar cheese, have more tryptophan per gram than turkey. Tryptophan doesn't have much of an impact unless it's taken on an empty stomach and in an amount larger than what we're getting from our drumstick. So why does turkey get the rap as a one-way ticket to a nap?

The urge to snooze is more the fault of the average Thanksgiving meal and all the food and booze that go with it. Here are a few things that play into the nap factor:

Fats: That turkey skin is delicious, but fats take a lot of energy to digest, so the body redirects blood to the digestive system. Reduced blood flow in the rest of the body means reduced energy.

Alcohol: What Homer Simpson called the cause of—and solution to—all of life's problems is also a central nervous system depressant.

Overeating: Same deal as fats. It takes a lot of energy to digest a big feast (the average Thanksgiving meal contains 3000 calories and 229 grams of fat), so blood is sent to the digestive process system, leaving the brain a little tired.

More Details Emerge About 'Oumuamua, Earth's First-Recorded Interstellar Visitor
 NASA/JPL-Caltech
NASA/JPL-Caltech

In October, scientists using the University of Hawaii's Pan-STARRS 1 telescope sighted something extraordinary: Earth's first confirmed interstellar visitor. Originally called A/2017 U1, the once-mysterious object has a new name—'Oumuamua, according to Scientific American—and researchers continue to learn more about its physical properties. Now, a team from the University of Hawaii's Institute of Astronomy has published a detailed report of what they know so far in Nature.

Fittingly, "'Oumuamua" is Hawaiian for "a messenger from afar arriving first." 'Oumuamua's astronomical designation is 1I/2017 U1. The "I" in 1I/2017 stands for "interstellar." Until now, objects similar to 'Oumuamua were always given "C" and "A" names, which stand for either comet or asteroid. New observations have researchers concluding that 'Oumuamua is unusual for more than its far-flung origins.

It's a cigar-shaped object 10 times longer than it is wide, stretching to a half-mile long. It's also reddish in color, and is similar in some ways to some asteroids in own solar system, the BBC reports. But it's much faster, zipping through our system, and has a totally different orbit from any of those objects.

After initial indecision about whether the object was a comet or an asteroid, the researchers now believe it's an asteroid. Long ago, it might have hurtled from an unknown star system into our own.

'Oumuamua may provide astronomers with new insights into how stars and planets form. The 750,000 asteroids we know of are leftovers from the formation of our solar system, trapped by the Sun's gravity. But what if, billions of years ago, other objects escaped? 'Oumuamua shows us that it's possible; perhaps there are bits and pieces from the early years of our solar system currently visiting other stars.

The researchers say it's surprising that 'Oumuamua is an asteroid instead of a comet, given that in the Oort Cloud—an icy bubble of debris thought to surround our solar system—comets are predicted to outnumber asteroids 200 to 1 and perhaps even as high as 10,000 to 1. If our own solar system is any indication, it's more likely that a comet would take off before an asteroid would.

So where did 'Oumuamua come from? That's still unknown. It's possible it could've been bumped into our realm by a close encounter with a planet—either a smaller, nearby one, or a larger, farther one. If that's the case, the planet remains to be discovered. They believe it's more likely that 'Oumuamua was ejected from a young stellar system, location unknown. And yet, they write, "the possibility that 'Oumuamua has been orbiting the galaxy for billions of years cannot be ruled out."

As for where it's headed, The Atlantic's Marina Koren notes, "It will pass the orbit of Jupiter next May, then Neptune in 2022, and Pluto in 2024. By 2025, it will coast beyond the outer edge of the Kuiper Belt, a field of icy and rocky objects."

Last week, University of Wisconsin–Madison astronomer Ralf Kotulla and scientists from UCLA and the National Optical Astronomy Observatory (NOAO) used the WIYN Telescope on Kitt Peak, Arizona, to take some of the first pictures of 'Oumuamua. You can check them out below.

Images of an interloper from beyond the solar system — an asteroid or a comet — were captured on Oct. 27 by the 3.5-meter WIYN Telescope on Kitt Peak, Ariz.
