Dating techniques are procedures used by scientists to determine the age of an object or a series of events. The two main types of dating methods are relative and absolute. Relative dating methods are used to determine only if one sample is older or younger than another. Absolute dating methods are used to determine an actual date in years for the age of an object.

Relative dating

Before the advent of absolute dating methods in the twentieth century, nearly all dating was relative. The main relative dating method is stratigraphy (pronounced stra-TI-gra-fee), which is the study of layers of rocks or the objects embedded within those layers. This method is based on the assumption (which nearly always holds true) that deeper layers of rock were deposited earlier in Earth's history, and thus are older than more shallow layers. The successive layers of rock represent successive intervals of time.

Since certain species of animals existed on Earth at specific times in history, the fossils or remains of such animals embedded within those successive layers of rock also help scientists determine the age of the layers. Similarly, pollen grains released by seed-bearing plants became fossilized in rock layers. If a certain kind of pollen is found in an archaeological site, scientists can check when the plant that produced that pollen lived to determine the relative age of the site.

Absolute dating

Absolute dating methods are carried out in a laboratory. Absolute dates must agree with dates from other relative methods in order to be valid. The most widely used and accepted form of absolute dating is radioactive decay dating.

Radioactive decay dating. Radioactive decay refers to the process in which a radioactive form of an element is converted into a nonradioactive product at a regular rate. The nucleus of every radioactive element (such as radium and uranium) spontaneously disintegrates over time, transforming itself into the nucleus of an atom of a different element. In the process of disintegration, the atom gives off radiation (energy emitted in the form of waves). Hence the term radioactive decay. Each element decays at its own rate, unaffected by external physical conditions. By measuring the amount of original and transformed atoms in an object, scientists can determine the age of that object.

Words to Know

Cosmic rays: Invisible, high-energy particles that constantly bombard Earth from all directions in space.

Dendrochronology: Also known as tree-ring dating, the science concerned with determining the age of trees by examining their growth rings.

Half-life: Measurement of the time it takes for one-half of a radioactive substance to decay.

Radioactive decay: The predictable manner in which a population of atoms of a radioactive element spontaneously disintegrate over time.

Stratigraphy: Study of layers of rocks or the objects embedded within those layers.

The age of the remains of plants, animals, and other organic material can be determined by measuring the amount of carbon-14 contained in that material. Carbon-14, a radioactive form of the element carbon, is created in the atmosphere by cosmic rays (invisible, high-energy particles that constantly bombard Earth from all directions in space). When carbon-14 falls to Earth, it is absorbed by plants. These plants are eaten by animals who, in turn, are eaten by even larger animals. Eventually, the entire ecosystem (community of plants and animals) of the planet, including humans, is filled with a concentration of carbon-14. As long as an organism is alive, the supply of carbon-14 is replenished. When the organism dies, the supply stops, and the carbon-14 contained in the organism begins to spontaneously decay into nitrogen-14. The time it takes for one-half of the carbon-14 to decay (a period called a half-life) is 5,730 years. By measuring the amount of carbon-14 remaining, scientists can pinpoint the exact date of the organism's death. The range of conventional radiocarbon dating is 30,000 to 40,000 years. With sensitive instrumentation, this range can be extended to 70,000 years.

In addition to the radiocarbon dating technique, scientists have developed other dating methods based on the transformation of one element into another. These include the uranium-thorium method, the potassium-argon method, and the rubidium-strontium method.

Thermoluminescence. Thermoluminescence (pronounced ther-moeloo-mi-NES-ence) dating is very useful for determining the age of pottery.

Dendrochronology is a dating technique that makes use of tree growth rings. (Reproduced by permission of .)

When a piece of pottery is heated in a laboratory at temperatures more than 930°F (500°C), electrons from quartz and other minerals in the pottery clay emit light. The older the pottery, the brighter the light that will be emitted. Using thermoluminescence, pottery pieces as old as 100,000 years can be dated with precision.

Tree-ring dating. Known as dendrochronology (pronounced den-dro-crow-NOL-o-gee), tree-ring dating is based on the fact that trees produce one growth ring each year. Narrow rings grow in cold or dry years, and wide rings grow in warm or wet years. The rings form a distinctive pattern, which is the same for all members in a given species and geographical area. Thus, the growth pattern of a tree of a known age can be used as a standard to determine the age of similar trees. The ages of buildings and archaeological sites can also be determined by examining the ring patterns of the trees used in their construction. Dendrochronology has a range of 1 to 10,000 years or more.

In mid-August, couples and lonely hearts packed a Brooklyn basement to hear scientists make sense of something the crowd could not: love. It was the 11th meeting of the Empiricist League, a kind of ad-hoc, small-scale TED Talks for scientists and the New Yorkers who adore them. In the back corner of the room, Christian Rudder sat by himself at the bar, nursing Stephen King’s “It.”

Rudder, the 39-year-old president and co-founder of the online dating site OKCupid, had come to deliver a distilled version of what he’s been working on for the last five years. In 2009, Rudder started OKTrends, an in-house blog for OKCupid, as a way to attract new members to a site that was nearly out of money. The posts covered such topics as the best camera angle for a profile picture and how people lie on their profiles — the mysteries online daters wonder about.

Soon, Rudder’s insights and wry wit were attracting millions of views. All of a sudden, Rudder, a one-time indie actor and rock star, had transformed himself into a dating laureate for the data age. By assembling users’ clicks and keystrokes into one place and spending hours inside Excel, Rudder had found a way to articulate our humanity.

Savvy book publishers took note. In 2012 Rudder proposed a book based on his blog, and Crown outlasted nine other publishers with a seven-figure bid. The book arrives on Tuesday, bearing the kind of Gladwellian title — “Dataclysm: Who We Are When We Think No One’s Looking” — meant to tell readers that a Big Idea lies between the covers.

Rudder’s talk at the Empiricist League borrowed from the book’s first chapter, covering the basics of whom we’re attracted to and why. Accompanied by a slideshow, he brought up a chart

Both charts are reprinted here from the book “DATACLYSM: Who We Are When We Think No One’s Looking” by Christian Rudder. Copyright © 2014 by Christian Rudder. Published by Crown, a division of Random House LLC, a Penguin Random House Company.

And then Rudder delivered the punchline. “And the male version is … ”

The crowd lost it — groans, hoots, hollers, total, uproarious laughter. It was enough to make me wonder why Louis CK doesn’t use Excel charts in his stand-up. Rudder, who has a kind of self-effacing charisma (“This segues to the next point on my shitty piece of paper here”) stammered for a bit and smiled. “It is kind of terrible.”

Later, somebody in the crowd shouted a question: “Could you point to an age at which, for a woman, it’s not even worth signing up?” Laughter again.

Rudder demurred. “This is attractiveness votes, so think of this as our proxy for lust,” he said.

The questioner interrupted. She was looking for a clear-cut answer, a capital-T Truth. “You know the number!” she shouted.

Rudder: “From the time you’re 22 you’ll be less hot than a 20-year-old, based on this data. So that’s just a thing.”

A flawed, messy, human thing that we probably could’ve intuited, but now, thanks to the data, we know. In the age of Big Data, the empirical has deciphered the intimate. And Rudder’s the one holding the cipher.

Rudder is now the president of OKCupid, but in 2009, before he started OKTrends, OKCupid was close to the end. The company had enough money to last until the end of the year, but without further investment that would be it. It was a free, advertising-supported dating site trying to scrape by in a market crowded with dozens of competitors and two hegemons: eHarmony and Match.com.

For over a decade, online dating had been taking advantage of Big Data before Big Data was even a buzzword. The hallmark of nearly any

Any except maybe Tinder-type sites, which pull from a Facebook account and rely heavily on profile images.

'>2 online dating site is the information a user volunteers in the hopes it’ll help find her love, sex or some combination of the two. That’s already a rich source of personal data to draw from, and OKCupid layered more on top of it. Every person coming to OKCupid has the opportunity to answer thousands of questions about what’s important to her and her prospective mate. The site runs the answers through some calculations to determine a match percentage for any given couple and then shows it to them. OKCupid’s mathiness was its sales pitch.

Rudder, who lives in the Williamsburg neighborhood of Brooklyn, is married and has never been on an online date. He co-founded the site in 2003, but he stayed out of the business for several years while touring with his rock band, Bishop Allen. In 2009, OKCupid’s cofounders called Rudder home to try to bring more users to the site by writing about its inner workings and its millions of members.

Their idea was to start a blog that shared the kinds of interesting tidbits about OKCupid users that they were already emailing around the office. The hope was that if Rudder cobbled together pithy insights into, say, how a woman’s body type correlates to her self-confidence, prospective users would read them and sign up.

These days, this kind of data-as-PR strategy is commonplace for startups. After the recent earthquake in Napa, Jawbone, which makes a fitness tracker, showed how the earthquake disturbed users’ sleep. And PornHub, the porn hub, recently outlined the different ways its users watch XXX content. But in 2009, Rudder said, “It was a different world because no company ever published any of their data about it. So even just the fact of publishing some stats felt kind of transgressive.”

Rudder’s first post about race — “How Your Race Affects The Messages You Get” — topped 1 million views. (Currently it stands at 1.2 million views.) This was raw shareable content before Buzzfeed or Upworthy had figured out the social Web. People, it seemed, liked reading about themselves.

But Rudder is no Virginia Woolf. His writing on OKTrends didn’t somehow speak to a larger, introspective truth. (Sample passage: “If you want worthwhile messages in your inbox, the value of being conversation-worthy, as opposed to merely sexy, cannot be overstated.”) Rather, the data did that for him.

“Often the deeper you go with it, or the more time you spend with these things, the more you see folk wisdom, or the shit everybody knows, confirmed with numbers.”

When Rudder highlights the differences in profile verbiage for those who like gentle or rough sex, it’s a voyeuristic peek into something you can’t even overhear at brunch. When he notes that a person who likes beer is more likely to want to sleep with somebody on a first date, it’s an intriguing question about our own personal correlations and causations. And when he writes that more people want sex daily rather than weekly as they move into their mid-20s, it’s a poignant insight into our shifting values as we grow from teenagers to adults.

To make these posts, it would take Rudder weeks to sort through the data his colleagues provided. He’d hunker down with a huge data set, load up Excel, and, as he puts it, “embrace the darkness.” “I’m very grim when I’m doing this stuff, as I’m sure you could imagine, and it’s just something about the grimness. You just live in it, man. If I have one talent it’s the ability to sit in front of anything, whether it’s Pro Tools or Excel or some postmodern novel or whatever it is, and just, like, do it.”

Sometimes the darkness doesn’t ebb even when Rudder hits publish. In late July, he wrote a post titled “We Experiment On Human Beings!” He was responding to the controversy over disclosures that Facebook manipulated users’ timelines to test how emotions spread through the network. Rudder thought Facebook got a raw deal in news coverage because all Internet companies run small- and large-scale experiments to help hone their products or make sense of their data. Among other things, his post disclosed that OKCupid sometimes inverted its match percentages, showing high marks to people who weren’t supposed to be compatible, therefore implying the opposite. OKCupid then measured whether those matches were less productive (i.e. led to fewer messages) than the traditional algorithm’s.

Rudder mused about experimentation in the same casual, jokey tone that he used to talk about the efficacy of users’ selfie habits. (“Maybe people just like each other because they think they’re supposed to? Like how Jay-Z still sells albums?”) The Internet went into umbrage mode, asking whether OKCupid had the right to change what it was showing its users for the sake of improving its product, and thus its bottom line. The Guardian, the BBC, and USA Today all covered the post. Tim Carmody, a tech writer, weighed in: “Ultimately, you ought to be ashamed to treat people and the things they make this way. It’s not A/B testing. It’s just being an asshole.” Were OKCupid’s users integral to its service or raw material to be manipulated?

Under fire, Rudder went on a podcast run by a producer for NPR’s “On the Media” a few days after the post was published. The studio ran hot — a producer in the booth interjected in the middle of his colleague’s interview to say:

Either you’re a company that’s trying to make the best possible product or you’re social scientists doing experiments about human behavior. And if you’re social scientists there are guidelines, and there are ethics, and there are things that scientists have to abide by. … In this conflation, some of the safeguards that social scientists would have get lost.

Rudder pushed back:

Part of what’s confusing about this experiment is the result. The algorithm does kind of work. … What if it had gone the other way? What if our algorithm was far worse than random? Then if we hadn’t run that experiment, then we basically are doing something terrible to all the users. This is the only way to find this stuff out. If you guys have an alternative to the scientific method, I’m all ears.

It got more contentious from there, which Rudder regrets. The flap has made him think hard about the value of sociological insights, and what the limits should be in the pursuit of them. “The more I think about it, a good line to hold to is, we don’t want to change anything the users have entered themselves. Then you are actually misleading people. Those are facts that you’re changing. Whereas an algorithm isn’t a fact, it’s a process.” People’s identities are sacrosanct, in other words, but how they’re introduced to whoever comes next is not.

Despite all this, from a business standpoint OKTrends has certainly been worth it. Mass media devoured even the noncontroversial posts from the beginning. As Dan Slater wrote in his comprehensive 2013 book on the online dating industry, “Love in the Time of Algorithms”

The book was recently released in paperback with a different title, “A Million First Dates.” If only there were an algorithm to predict marketable book titles.

The mainstream print media jumped all over Rudder’s dispatches. In 2010, the OKTrends blog served as fodder for at least half a dozen New York Times articles and blog posts. “The PR that was generated from the blog was transformational for our brand,” says [OKCupid co-founder Sam] Yagan, who appeared on CNN and elsewhere to discuss some of the OKTrends findings.

OKCupid discovered earlier than most what data could tell us. As data has become more entwined with our humanity, and vice versa, it’s easy to forget what the point of it all is. Having, say, a central repository of friends’ birthdays so we don’t have to keep them in a separate calendar seems to be about little more than convenience. But Rudder and OKTrends showed that Big Data had more to offer. With every decision we make online we leave a trace about our intentions, conscious or otherwise. When all those traces are gathered together into one central space, they form a reservoir of knowledge about who we are.

Since OKTrends was started, 25 million new people have joined OKCupid; in the five years before the blog, the site had attracted 5 million. Two years after the first post, the media company IAC scooped up OKCupid for $50 million. If anybody knows correlation isn’t causation, it’s Rudder, but the start of OKTrends marked a new chapter in the company. Chris Coyne, one of the founders, told me the site “certainly became profitable shortly after that.” Rudder, and our data, had helped to salvage the company.

Rudder’s childhood had the same shambling, itinerant quality as his career. His family moved around a lot — Cleveland, Mexico City, Houston, Louisville, Little Rock, wherever his dad’s banking job took them next. “They were very nontraumatic-type moves. I don’t know, it was just a thing that happened,” Rudder said.

Along the way, he wasn’t aspiring to be anything in particular. Not a matchmaker, nor a data scientist, nor a star of a film that New York Times critic A.O. Scott named one of his 10 best of the year in 2005, nor the guitarist for a beloved indie pop band. He stumbled into all of it — they were just things that happened.

They started happening when Rudder went to Harvard in 1993. “I originally went thinking I would do math and physics and then I took some math classes my first year and I was like, whoa, fuck this. First, everybody was way better than I was. Second, I just didn’t like college. Period.” So he took a leave of absence and moved back to Little Rock, where he “hung out, sat around, worked for my girlfriend’s dad. Dicked around in Excel, basically.”

But even Rudder, who has used Excel in almost every job he’s had, could only dick around for so long. A year later he went back to Harvard, determined to change course even if he was right back where he started. Gone were the math and physics courses, in was the English curriculum. And then by senior year it was back to math. “Not to pick a fight with any post-structuralist critics or anything like that, but a certain frame of mind can only tolerate that kind of academic stuff for [so long],” he said. He earned a math degree in 1998.

After graduating, he followed friends to Texas, where he worked on a financial graphing tool (more Excel) and thought about becoming a baker. But the people he worked with at the bakery weren’t his style. “I just couldn’t handle the hippies. I never smoked pot or anything and I can’t deal with the searcher mindset, especially in a work environment where I was like, ‘I gotta get this done,’ and they were like, ‘Dude, man, we get paid by the hour.’”

And so, tired of the searchers, Rudder went searching. Like any sensible 20-something in the late ’90s, he turned to the Internet. He knew a guy who knew a girl who knew a startup looking for writers, so he got a job at TheSpark.com, and moved to Boston for it. TheSpark was a kind of proto-Buzzfeed that offered lifestyle quizzes and would later grow into SparkNotes, a CliffsNotes-knockoff on the Web. Rudder was the content guy, writing satirical humor posts (“How to Lose a Fight So The Other Guy Goes to Jail”) as a way to get people to stay after they came for the quizzes.

Those were the posts that, many years later, would mature into OKTrends. It helped that TheSpark is also where Rudder met Sam Yagan, Chris Coyne and Max Krohn, all of whom would go on to found OKCupid with him.

A few years after Rudder left TheSpark he and a Harvard pal, Justin Rice, self-released an album as the band Bishop Allen. The album’s fifth track gives a shoutout to Excel, which Rudder used to put the album together. “To figure out where edits should be, Christian would use spreadsheets. So he’d be like, ‘OK, we’re at this BPM, I know 11 measures in I need to splice in this drum fill,’ so he would figure out the exact moment in the timecode to put the edit,” Rice recalled.

Within five years, the band’s songs would be featured in commercials for Sony and Target, they’d make a cameo in the 2008 film “Nick and Norah’s Infinite Playlist,” and the tours and CDs would bring in enough income for Rudder and Rice to focus on music more or less full time. Immersing himself in Bishop Allen was how Rudder paid the bills while OKCupid struggled to find its audience.

Dating Site For Scientists And Inventions

Bishop Allen wasn’t Rudder’s first taste of minor fame. In 2001, his old roommate from Harvard, Andrew Bujalski, cast him in his first movie, “Funny Ha Ha.” It was a kind of meditation on what it’s like to be a young adult stuck in mediocrity, and know it. Rudder played Alex, the unattainable guy that the film’s lead, Marnie, is chasing. Bujalski recalled over email, “He had zero interest in pursuing acting, but he brought complete honesty and fearlessness to it and knocked my socks off.” The movie made critics swoon when it came out in 2005, and they dubbed “Funny Ha Ha” the birth of a new genre of film: mumblecore. Rudder, the math major, satire-writer, Excel-dicker, had helped transform indie cinema. Just one of those things that happened.

“There isn’t really, like, a thread. I’ve definitely never planned any of this stuff out,” Rudder said, looking back. Rice, though, does see a throughline. “I think there’s a method for thinking that he can bring to bear on any given task. Whatever dissimilarities there are between the various kinds of things that he’s doing, they’re definitely united in that they allow for a systematic approach.”

If OKTrends was Rudder’s sketchpad, “Dataclysm” is his reluctant manifesto. The book covers data from OKCupid, Twitter, Facebook, Google and other sites to describe how Big Data has already changed our lives, and all the changes to come. “If there’s one thing I sincerely hope this book might get you to reconsider,” Rudder writes in the introduction, “it’s what you think about yourself. Because that’s what this book is really about. OKCupid is just how I arrived at the story.” Rudder wants to convince us that data is how we can arrive at our own stories. “As the Internet has democratized journalism, photography, pornography, charity, comedy, and so many other courses of personal endeavor, it will, I hope, eventually democratize our fundamental narrative.” Gone are the days when our moment is defined only by researchers, effete columnists or whoever else gets to say what a millennial is. Now, Rudder argues, the story is ours to tell.

But if submitting to Big Data is what’s required, are we interested in telling it? Rudder started writing the book in a pre-Edward Snowden era, when the conversation about data was largely about its possibilities, not its perils. There’s a telling passage early in the book when Rudder writes, “If Big Data’s two running stories have been surveillance and money, for the last three years I’ve been working on a third: the human story.” But that doesn’t go quite far enough. These days, isn’t the human story a combination of surveillance and money?

Rudder acknowledges that more data often doesn’t lead to more insight for anyone other than the company receiving it. “We want people to send more messages on OKCupid, but it’s unclear if that’s actually good for people,” he said. Our data, when amassed, can tell a larger story, sure, but we usually aren’t the ones actually doing the telling. It’s more often the NSA, or OKCupid, or some third party who bought the data from Twitter, who controls the narrative. Data may be helping to “make the ineffable effable,” as Rudder writes in “Dataclysm,” but the mass of humanity is still being interpreted through someone else’s filter.

And even then, the stories that are being told aren’t necessarily incisive ones. Rudder’s book is filled with interesting factoids — online daters are copying and pasting their messages to maximize the number they send; people of every race mention pizza on their profiles; the most popular place for a Craigslist missed connection in the South is Walmart — but they rarely surprise. They’re cocktail chatter, not sociological breakthroughs. “It’s very rare that you find that counterintuitive thing, much to the book PR agent’s chagrin,” Rudder said.

Perhaps that’s the breakthrough: that we’re actually quite good at intuiting our inner workings and secret desires already. “Often the deeper you go with it, or the more time you spend with these things, the more you see folk wisdom, or the shit everybody knows, confirmed with numbers,” Rudder told the Empiricist League. His real contribution isn’t that he offers 100 different insights into the way humans behave; it’s that 90 of the 100 are things we had a sense of already. Rudder’s posts and book are at their best when they act as little more than a mirror. We are who we thought we were. Now we just have the numbers to confirm it.

CLARIFICATION (Sept. 9, 9:46 a.m.): Christian Rudder took a year-long leave of absence from Harvard but did not drop out of school for that period, as this article originally stated.
