February 16, Geologists from the University of Innsbruck shed new light on a long-lasting debate about the trigger mechanism of large rockslides. Lake mud in two Alpine lakes in Tyrol reveal that rare strong earthquakes are the final cause of multiple, prehistoric rockslides in the Eastern Alps. The study has now been published in the journal Nature Communications. Many steep valleys in the European Alps show the relicts of large rockslides, during which several hundreds of million cubic meters of rocks get instable, collapse and impact everything on their path. This enigmatic pattern has puzzled researchers over the last decades and fuelled some intense debates.

Radiocarbon dating - Wikipedia

Woodbank does not monitor or record these emails. Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved. You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular. Pre B. We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind. Volta's pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications.

The majority of Egyptologists agree on the outline and many details of the chronology of Ancient Egypt. This scholarly consensus is the so-called Conventional Egyptian chronology , which places the beginning of the Old Kingdom in the 27th century BC, the beginning of the Middle Kingdom in the 21st century BC and the beginning of the New Kingdom in the midth century BC. Despite this consensus, disagreements remain within the scholarly community, resulting in variant chronologies diverging by about years for the Early Dynastic Period , up to 30 years in the New Kingdom , and a few years in the Late Period.

Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants.
