FAQ – Radioactive Age-Dating

I made an app to estimate your probability of finding a girlfriend! It is commonly assumed that having a high paying job will make you more attractive. Physical characteristics like height and muscle may also play a role. We try to identify which attributes are the most predictive, and which are mere assumptions not supported by data. Off the top of my head, I came up with the following attributes: In these cases, I tried to assign 1 to about half the population, and 0 to the other half. Yeah, if you expected a statistically rigorous study, you can stop reading now. To collect data, I tabulated every person I could think of and rated them either 1 or 0 in each of these attributes. The three variables that are the most significant are:

Slowly and painstakingly, geologists have assembled this record into the generalized geologic time scale shown in Figure 1. This was done by observing the relative age sequence of rock units in a given area and determining, from stratigraphic relations, which rock units are younger, which are older, and what assemblages of fossils are contained in each unit.

Using fossils to correlate from area to area, geologists have been able to work out a relative worldwide order of rock formations and to divide the rock record and geologic time into the eras, periods, and epochs shown in Figure 1.

The empirical findings in Everybody Lies are so intriguing that the book would be a page-turner even if it were structured as a mere laundry list. But Mr Stephens-Davidowitz also puts forward a deft argument: This brilliant book is the best demonstration yet of how big data plus cleverness can illuminate and then move the world.

No Fury Like a Data Scientist Scorned Here is a quaint story of a data scientist who had a short telephone interview for a position at online dating site and .

He graduated from Grinnell College with a degree in chemistry. There, he met his future wife, Lorna Laurie McCleary. For graduate school, they both attended the University of Iowa , where he was awarded an M. Both were then sent to work on the Manhattan Project , first at the University of Chicago and then at Oak Ridge, Tennessee , where he encountered mass spectrometry. After a postdoctoral year at Chicago, Patterson moved with Brown to the Division of Geology later the Division of Geological and Planetary Sciences at the California Institute of Technology in , as founding members of its geochemistry program.

He and Laurie had four children. Zircons are extremely useful for dating since, when they are formed, they possess tiny imperfections of uranium inside them but no lead.

Carbon , Radiometric Dating and Index Fossils Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.

Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information.

As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.

Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods. This uses radioactive minerals that occur in rocks and fossils almost like a geological clock.

Idealized and simplified diagram of the Grand Canyon There are a number of lava flows on the plateau that the canyon is cut into yellow in Figure 1, above. These lava flows are Cenozoic in age, and some of them spill into the canyon. The walls of the canyon are mostly cut into horizontal rock layers of Paleozoic age green in Figure 1, above. There is an angular unconformity at the bottom of the Paleozoic layers. An angular unconformity is the result of tilting and eroding of the lower layers before the upper ones are deposited.

These tilted and eroded layers are Precambrian in age blue in Figure 1, above. The geological relationships of the various formations are quite clear. The lava flows which spill into the canyon must be younger than the canyon. The canyon must be younger than the rock layers that it cuts into. The sediments above the angular unconformity must be younger than the sediments below it. The ordering of events which resulted in Figure 1 must be: The blue layers are deposited.

Dating Fossils – How Are Fossils Dated?

Is carbon dating accurate? Only to a certain extent. In order for carbon dating to be accurate, we must know what the ratio of carbon to carbon was in the environment in which our specimen lived during its lifetime. Unfortunately the ratio of carbon to carbon has yet to reach a state of equilibrium in our atmosphere; there is more carbon in the air today than there was thousands of years ago.

Furthermore, the ratio is known to fluctuate significantly over relatively short periods of time e.

Judge hands CNN a victory in fight with White House One of the bigger pieces of product news at Facebook’s F8 developer conference this week was the announcement that Facebook will soon turn on a new dating feature. Dr Steve Carter, a data scientist who helped design and build the psychometric and relationship models that became the basis of eHarmony — the dating site where he was a founding member and worked for nearly 20 years — is working at the social network, out of its offices in Los Angeles.

His LinkedIn profile notes that he joined Facebook in August Back in January, there was a brief mention of Carter doing work for Facebook, but at the time it was not known that he’d actually left eHarmony months before that. It seems that he’s only recently updated his profile with that information, coinciding with Facebook now finally making its dating intentions public.

We have reached out to Facebook and the company declined provide a comment for this story. Carter’s profile on LinkedIn describes him as a data science manager, “helping Facebook get even better at making meaningful and beneficial connections between people and communities. Before this, he held a number of roles at eHarmony, starting as a research analyst on the founding team in , before eHarmony had even launched, working his way up to chief scientist at the company, which has had backing from the likes of Sequoia and TCV in its history.

In that time, he also picked up four patents in online social matchmaking, including one for employment matching.

Yellowfin Team The first couple of weeks of the Australian new year is an odd time. In theory the holiday break is over but summer is still in full swing. The roads are uncluttered and when you look around the workplace, there are plenty of vacant seats. Business may have officially resumed but nobody is taking it too seriously. This is the ideal time for channellling creative ideas and plannning projects for the year ahead. We mention all of this in an attempt to explain why the two of us have been busy planing a Yellowfin webinar about speed dating, love and data science.

Our objective is to show how a data science workflow based on the CRISP-DM methodology can be integrated into Yellowfin in order to develop a model that can be deployed and productionised for operational use. Along the way we will demonstrate how data scientists can streamline the data wrangling, feature engineering and visualisation steps.

Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.

History of the greenhouse effect and global warming By S. Enzler MSc History of the greenhouse effect and global warming Svante Arrhenius was a Swedish scientist that was the first to claim in that fossil fuel combustion may eventually result in enhanced global warming. He proposed a relation between atmospheric carbon dioxide concentrations and temperature. He found that the average surface temperature of the earth is about 15oC because of the infrared absorption capacity of water vapor and carbon dioxide.

This is called the natural greenhouse effect. Arrhenius suggested a doubling of the CO2 concentration would lead to a 5oC temperature rise. He and Thomas Chamberlin calculated that human activities could warm the earth by adding carbon dioxide to the atmosphere. This research was a by-product of research of whether carbon dioxide would explain the causes of the great Ice Ages. This was not actually verified until After the discoveries of Arrhenius and Chamberlin the topic was forgotten for a very long time.

At that time it was thought than human influences were insignificant compared to natural forces, such as solar activity and ocean circulation. It was also believed that the oceans were such great carbon sinks that they would automatically cancel out our pollution.
