Beyond the specific topic of natural 14 C, it is hoped that this account may serve as a metaphor for young scientists, illustrating that just when a scientific discipline may appear to be approaching maturity, unanticipated metrological advances in their own chosen fields, and unanticipated anthropogenic or natural chemical events in the environment, can spawn new areas of research having exciting theoretical and practical implications. This article is about metrology, the science of measurement. More specifically, it examines the metrological revolutions, or at least evolutionary milestones that have marked the history of radiocarbon dating, since its inception some 50 years ago, to the present. The series of largely or even totally unanticipated developments in the metrology of natural 14 C is detailed in the several sections of this article, together with examples of the consequent emergence of new and fundamental applications in a broad range of disciplines in the physical, social, and biological sciences. Following the discovery of this year half-life radionuclide in laboratory experiments by Ruben and Kamen, it became clear to W. Libby that 14 C should exist in nature, and that it could serve as a quantitative means for dating artifacts and events marking the history of civilization. The search for natural radiocarbon was itself a metrological challenge, for the level in the living biosphere [ca. That was but the beginning, however. The year before last marked the 50th anniversary of the first edition of Willard F. Eight years later Libby was awarded the Nobel Prize in Chemistry.

A new facility and powerful new tools for dating sedimentary archives have been developed with the help of an EU-funded initiative, enabling scientists to better understand climate and environmental changes. The aim of the HIRESDAT High-resolution dating of sedimentary archives project was to develop facilities that would enable the highest possible resolution for the dating of sedimentary archives of past climatic and environmental changes such as global warming, carbon dioxide levels, droughts and monsoons.
High resolution achieved allowed these results to be correlated with known variations in the global climate taken from marine records. By identify their precise age, scientists are now able to better understand the possible causes of environmental changes observed in sedimentary archives.

When Tinder became available to all smartphone users in , it ushered in a new era in the history of romance. It aimed to give readers the backstory on marrying couples and, in the meantime, to explore how romance was changing with the times. But in , seven of the 53 couples profiled in the Vows column met on dating apps. The year before, 71 couples whose weddings were announced by the Times met on dating apps.
Dating apps originated in the gay community; Grindr and Scruff, which helped single men link up by searching for other active users within a specific geographic radius, launched in and , respectively. With the launch of Tinder in , iPhone-owning people of all sexualities could start looking for love, or sex, or casual dating, and it quickly became the most popular dating app on the market. But the gigantic shift in dating culture really started to take hold the following year, when Tinder expanded to Android phones, then to more than 70 percent of smartphones worldwide.
Shortly thereafter, many more dating apps came online. But the reality of dating in the age of apps is a little more nuanced than that. Completely opposite of what I would usually go for. Today, she can no longer remember what it was. Plus, Mike lived in the next town over. But after a few weeks of chatting on the app and one failed attempt at meeting up, they ended up on a first date at a local minor-league baseball game, drinking beer and eating hot dogs in the stands.

We present an overview on different environmental zones within coastal areas and summarise the physical basis behind the three most important methods that are available to date Holocene coastal sediments. Besides radiocarbon and uranium series dating, Optically Stimulated Luminescence O sl has increasingly been applied for dating in coastal settings over the past decade. This is illustrated by a number of case studies showing that O sl can be applied to sediments from almost any kind of coastal environment, covering a potential dating range from some years up to several hundred thousand years.
O sl dating may hence be the method of choice for deciphering natural environmental change along coasts as well as the presence and the impact of human occupation in such areas. In addition, we briefly show how and where these dating methods could be applied to constrain the palaeo-environmental context of an archaeological site at Vohemar in north-eastern Madagascar.

The discovery of abrupt paleo-climate change events and the prediction of environmental changes in the future time have raised an urgent request for high-resolution paleo-environmental records.
