Time

« previous episode | next episode »

Jorge Luis Borges wrote, "Time is the substance from which I am made. Time is a river which carries me along, but I am the river; it is a tiger that devours me, but I am the tiger; it is a fire that consumes me, but I am the fire." And it’s still as close a definition as we have. This hour of Radiolab, we try our hand at unlocking the mysteries of time. We stretch and bend it, wrestle with its subjective nature, and wrap our minds around strategies to standardize it...stopping along the way at a 19th-century railroad station in Ohio, a track meet, and a Beethoven concert.

Guests:

Brian Greene, Jay Griffiths, Ben Rubin, Dr. Oliver Sacks and Rebecca Solnit

Unlocking The Secrets of Time

Neurologist Oliver Sacks tells us about his fascination with time. As his soon-to-be-published essay in the New Yorker will tell you, he's been fascinated by time and has used photography to get inside it since he was a little boy. We'll hear a recording of a baby becoming a young ...

It's All Relative

Both physicist Brian Greene and neurologist Oliver Sacks explain the very strange, very subjective nature of time.

The elasticity of experience is expressed by sound artist Ben Rubin in a piece he produced for The Next Big Thing. We include an excerpt on being in "the zone." ...

Ruled By Time

The self-declared Independent State of Trolheim does not recognize GMT (Greenwich Mean Time). Jay Griffiths argues that the question of what time it is in inextricably bound up with issues of power and politics. And we'll hear a piece from producer Aaron Ximm on the experience of listening to Beethoven's ...

You did not get the relatitvity explanation right. Special relativity says, if two people with watches are traveling at a constant velocity relative to each other, they both see each the others watch as moving slow. Suppose one should deacclerate (or accelerate) to catch the other. The one that does would find the others watch is fast (or slow). The accleration fixes the differences of the clocks. Likewisw clocks located in large acceleration fields (say the gravitional surface of the planet)run slower than clocks in a low accelaration fields (located off the planets surface). For the most part, for people moving with low velocities compared to the speed of light on the surface of the earth, time is the same for everyone.

I love RadioLab, but was highly distressed to hear a section of the Podcast/Radio show titled "Unlocking the Secrets of Time" aired on Jan. 4th, 2014.

At 8:02 in the recording a little girl says this:

"...Tony, if, um, if a dog makes wee wee in the house, if he's, if you have to make him house broken, if he makes wee wee in the apartment, you have to slap him with a newspaper, then if he doesn't do it again he's house broken…."

Hitting an animal, especially a puppy, should not be encouraged in any form, even from a little girl that knows only what her parents have taught her, which sadly in this case is—it's OK to hit a dog. This section could have easily been edited out and I am disappointed that RadioLab did not catch it and left it in for so many people to hear, and thus condone, whether intentionally or not.

I would encourage you to remove this section of the podcast.

Sincerely,
Terri

Hi,
I think Radiolab has the potential to become your best program.

It is provocative and goes quite far but then stops short. I think this is because you feel you have to/want to entertain. This results sometimes in flippancy, as for instance when you ridiculed that eminent physicist's kind gesture of letting you in on how he tries to feel time and electrons etc.

There was also a fairly easy way to go deeper and investigate the stretching to time in meditation - it would have been the felt-experiential side opposed to the hard scientific side.

As we finally are getting better science, we are realizing that there is more under the sun than our imposed/imposing conceptual armory has dreamt of.

Please do not shun depth, we are a capable audience, and leaven with such humor as does not demean or cut off the sense of awe - that all good scientists feel and want to transmit.
Thanks and all the best ,

Johannes

This episode opened my understanding enough to reconsider the meaning of this scripture...

2 Peter 3:8
But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day.

Someone on the show said the sun is directly overhead at noon. As most educated people know, this can only happen within the Tropics, and not in the US. That guy needs to get outside more.

Also, even though it is now accepted as an idiom, I wish you would not allow the expression "centered around". Try drawing a picture of that.

I missed part of the show, when you were talking about athletes perceiving time so much faster. I had an experience, at a 3 month silent meditation retreat, where my task was to be present in every moment. Near the end of the retreat, I was holding out my palm with sunflower seeds to feed the chickadees in the woods. I noticed as I watched the birds approach that I was seeing exactly how they shifted their feathers, like ailerons on a plane, to fly between the thick evergreen branches. Normally that would have just been a blur. And in that moment I remembered Leonardo da Vince's drawings of birds and their wings, and realized that in addition to drawing from deceased bird models, he had also watched them this closely, and this quickly, or is it slowly, as I was in that moment.

If a whale (or similarly paced out of water animal) heard the slowed down Beethoven, would it sound the same to them as it does to us? Or similarly, if Beethoven were to be sped up to the tempo of a hummingbird, would a hummingbird hear what we hear?

Why do you guys post this link to http://www.notam02.no/web/ if the Beethoven's 9th is un available - so bogus - marketing technique! If anyone has a direct link to the music I would appreciate - not some smoke and mirrors marketing technique hokus pokus.

At a previous residence, a beetle would scrape itself along a lighted wall every night at 10 p.m., presumably to get my attention because it wanted the lights turned out. (It also did this once when I left a pot of boiling water unattended, believe it or not.)

Good program. The Nova episodes that Brian Greene hosted earlier this year (these should be available for free viewing on the Nova web site) talk about the latest theories on time.

Railroad Time did not just happen. It was Samuel Pierpont Langley (who later became Secretary of the Smithsonian Institution) of Pittsburgh's Allegheny Observatory who made it possible to have a time standard for the railroads (and everyone else). And, like many things, it happened as a matter of financial necessity for the Allegheny Observatory.

When Langley arrived at the Allegheny Observatory in 1867, there was little money for actual astronomical research. With the strong support of Pennsylvania Railroad Vice President William Thaw, Langley started using the Observatory to determine precise time, by observing certain stars. He then sent time signals, by telegraph, to railroads, cities, and other subscribers. Annually, this time subscription service raised nearly $3,000 (a huge sum in that era) to fund Observatory research.

Interesting program. You might want to check out an interesting movie called Nostalgia for the Light by Patricio Guzman. An astronomer in it makes the case that everything that happens to us happens in the past. What we see with a telescope happened up to a great time ago, while by the time we hear what someone says a small amount of time has passed since it was said. This is a side idea in a beautifully done production with more important issue to examine and well worth viewing.

time & insects, in 1983 I would bike out Flatbush avenue to make my art at the end in Dead Horse Bay. I use the reeds that grow on the show and make my art on the tidal estuary sand and then wait for the tide to come in so the art is only in the water. in late afternoon at a particular time the crickets would start it's song. get those last photographs and go home. wonderful light and communing to the earth at the same time.

Hello everyone. I live in the UK and adore radiolab...I am itching to know what the piece of music at the end of the section on the recording of the little girl from birth to twelve is. Can anyone help? Sorry to be a pain if its obvious.

I often listen to music on my iPod on my way to work in the morning, and have discovered a strange phenomenon. Whenever I yawn, the tempo of the music seem to slow down a little. When I have completed the yawn, the music is back to normal tempo. While the pitch of the music has remained constant, during the yawn, I will experience a 127 bpm tune drop to 124 or so bpm (difficult to measure, obviously).

Has anyone else experienced this? I find it fascinating that one can alter the perception of time simply by yawning :-)

I listen to the show on SAT mornings and am enamored with it. Being a social scientist (sociologist), I appreciate and acknowledge the scientific approach while giggling at the humor and sharp conclusions. This is my favorite NPR show (well, the car dudes aren't far behind ...). The piece on "TIME" was fascinating - absolutely fascinating - even though I would still argue that a large portion of our understanding of "time" is socially constructed. So, I want to leave you guys a "hats off" compliment, and hope there will be many more seasons to listen, but if you ever go back to the issue of time, I wish you'd also talk to some sociologists.

1/7/2012 between 3-3:30pm I heard an (humorous) essay (sort of) on Time, e.g. amount of time in one's life spent filing nails, eating, blinking, laughing, singing, in other words doing innocuous things, as well as important things.
Grand Rapids, MI PBS station perhaps.
Can you identify the essay/poem/reading please?

excellent article on time -
consider that time is three dimensional one (forward and back) is past, present and future- up/down and left/right are alternative probabilities, just as all our three physical dimensions exist so too does all time.

this theory was put forth by Jane Roberts (a mystic) in the 60's.

I've been listening to Radiolab for quite a while now and I still think this episode is my favorite. It has all the greatest qualities of Radiolab; Oliver Sacks, stories, science, and insight. :) Thanks so much, everyone.

Try this small experiment that will dissolve your mind's conception of time when run in tandem with your biological clock.

Most people before going to be take a glance and look at the clock...the next time you go to bed, conscientiously think about not looking at the clock or thinking about how many hours of sleep you will get. Simply get in bed put your head down and relax. You will be surprised to find that regardless of the amount of time you sleep 5hrs, 8hrs, etc. your body will feel rejuvenated and you will have deceived your mind from sensing fatigue.

P.S. Radiolab is the new television. Jump on the bandwagon.

About the thing where time has already written our history and it is just there frozen and waiting to happen? Time is the order those events happen. If it weren't for time, our universe wouldn't work. That is to say that if it weren't for time it could be as if some one were in New York, watching the sunset with the Statue of Liberty, the next thing we know, we're not born yet and the Statue is still being under construction!! Time puts the events into an order that makes sense.

Relating to the section about how time is relative to people, and how people in "the zone" perceive things more slowly than they actually happen: I have this experience while I'm playing music. When I play music, and play it well, it may feel absolutely perfect to me, just the right tempo. Curiously, though, when I listen to recordings of my playing, the music is too fast. Even music I've just played and felt was just right.

what you describe is true in a way but you think of the word time in it's poetic meaning

basicly time is nothing more the a different word for change... regerstating that change

For a week in my Senior year in high school I experienced severe time dilation. Everything was moving at normal speed, by my perception was that it all was going super fast. Frustrating, annoying, and overwhelming. Thankfully it went away in a week.

Andrew from Chicago

What if time doesn't exist? It seems to me that the goal for all of us is to remain present; to acknowledge that, in fact, all we really have is the present. Sure, our world and sun and lives exist in cyclical motion and things change, but to me the significance of that isn't found by breaking down time into its component parts to "figure it out," but rather, it shows us that the present is never the same. The present is where it's at. As we know, time is relative; subjective. In accepting this, try to just ignore time. Stop thinking about the past, stop thinking about the future. Imagine we are just people moving around in space, with events occurring all around us. Our present automatically encompasses all that has already happened so there is no use in dwelling on it. By accepting that the present is all there is, we realize we have much more time than we ever imagined. As the Zen masters say, "when you wash the dishes, wash the dishes."

I was wondering if the Oliver Sach's patient Mirin(?) V ( for whom time had slowed) saw the world around him move at a blistering pace and conversely for the female patient Hester Y. Did she see the rest of the world move at a snail-like pace. Any answers?

I was just listening to some episodes of radiolab that I missed... and well it's a good thing I did. The time episode really explained a lot to my boyfriend and I. We have been together for over a year and a half and really find the other person to be interesting and fascinating but we also have a lot of mis-understandings. What we realized is that we go at different speeds. Be is very speedy and gets a lot done. I am more slow, methodical and detail oriented. We totally operate on different planes! It was quite eye opening to think of things in these terms but at the same time makes us question if we are fundamentally in-compatible.

Thanks for the insite... not that we know what to do with it.

I do heart radiolab and find it to be just the right speed.

Patrick from California:

He considered real noon, i.e. what them cowboys called "high noon," where the sun appears to be at its highest point in the sky. That's when you're facing closest to the sun for that particular day.

The "noon" that we use to refer to a certain time in our standardized time zones is, generally speaking, not the same time as high noon, as it's a rather arbitrarily set time. Standard time zones were invented originally so that places linked by railroads would have synchronized times. Otherwise, they don't really have much significance in terms of positions of the sun, celestial bodies, etc. I know from my own casual observations that at least for part of the year here on the American east coast, high noon is actually around 1 or 2 PM.

Reading a book that talks about how Eratosthenes (ca. 276-194 B.C.) estimated the circumference of the earth by noting the length cast by a shadow at exactly noon in Alexandreia and Syene. He surmised that the difference in shadow length combined with the distance between the cities could tell him the circumference of the earth. My question is this: How did he do this if time was not standardized until the 1900's and train schedules as you mentioned :-)

The theory with setting two rolexes would work but because a rolex doesn't keep perfect time considering the fact that Rolex watches are self wound automatic peices. Two Rolexes will never keep perfect time. If you lay one down on its side and one on its back the one on its back will be faster than the one on its side. The thoery should have been stated with two quartz battery watches because they will keep better time than a Rolex

You guys failed to touch upon an instance where we all experience time at a significantly accelerated clip: our dreams. Personally, I have always believed this to be because we are unhampered by the physical world. Any thoughts?

Jennifer, I believe what you are looking for is the Japanese musician Nobukazu Takemura. It plays between 21:30 and 23:00? I think it's the song "Kepler" from the album Scope.
