Brian McNeill, University Public Affairs Boxes upon boxes filled with the fossilized remains of a mastodon that died in Virginia more than 18, years ago are being hauled up the steps to Virginia Commonwealth University’s Virtual Curation Laboratory, where the massive Ice Age animal’s fossils—including the tip of a tusk, a very worn tooth, toe bones, a rib bone and a mandible—are slated to be 3-D scanned. The mastodon’s tooth was first discovered in by a bricklayer named Lawnell Hart, who then enlisted the help of College of William and Mary geology professor Jerre Johnson, Ph. Hart and Johnson visited the site again and found additional fossils, but the property owners would not grant them permission to conduct a proper excavation. In my cabinet, I kept that stupid fragment of the jaw and this tooth that was cavity ridden. In , the site’s new property owners granted him permission, and Johnson, along with a team of volunteers, excavated a staggering quantity of the mastodon’s remains, which suggest that the animal was hunted and butchered by pre-Clovis American Indians during the last Ice Age. The Virtual Curation Laboratory 3-D scanned this mastodon jaw fragment with an abscess, which was excavated near Yorktown, Virginia. We probably know its predator. These are really neat discoveries.

The West African Craton generally consists of a Precambrian granitized basement and its surrounding Neoproterozoic mobile belts, forming the larger central, southern and western part of the country. This region has been mostly affected by the Pan-African tectono-thermal event. In the north, beginning from Tangier in Morocco via northern Algeria to Tunis in Tunisia, a folded chain extends over the entire length of the Maghreb.

This belt is part of the Alpine chain, with its features more resembling the Betic and Apenine segments of the Alpine unit.

Its name is said to reflect a legend that states the prophet Job “Ayub” in the Quran visited this place and brought forth a spring of water by the blow of his staff on the ground. The water of this well is said to be exceptionally pure, and is regarded for its supposed “healing qualities. Ismail Samani mausoleum The Ismail Samani mausoleum 9th—10th centuries , is one of the most highly esteemed work of Central Asian architecture.

It was built in the 9th century between and as the resting-place of Ismail Samani —the founder of the Samanid dynasty , which was the last native Persian dynasty to rule the region in the 9th to 10th centuries, after the Samanids established virtual independence from the Abbasid Caliphate in Baghdad. The site is unique for its architectural style which combines both Zoroastrian and Islamic motifs. The building’s facade is covered in intricately decorated brick work, which features circular patterns reminiscent of the sun—a common image in Zoroastrian art from the region at that time which is reminiscent of the Zoroastrian god, Ahura Mazda, who is typically represented by fire and light.

The building’s shape is cuboid, and reminiscent of the Ka’aba in Makkah, while the domed roof is a typical feature of mosque architecture. The syncretic style of the shrine is reflective of the 9th to 10th centuries—a time when the region still had large populations of Zoroastrians who had begun to convert to Islam around that time.

The shrine is also regarded as one of the oldest monuments in the Bukhara region. At the time of Genghis Khan’s invasion, the shrine was said to have already been buried in mud from flooding. Thus, when the Mongol hordes reached Bukhara, the shrine was spared from their destruction.

From studying coral reef genomes to reef connectivity, these labs are devoted to researching the intensely interesting and dynamic ecosystems within our waters. Geodynamics Research and Visualization Lab The Geodynamics Research and Visualization Lab models the solid-state deformation of the lithosphere and upper mantle, with a focus on plate boundaries. This is accomplished through field work, analytic modeling, large-scale numerical modeling, data assimilation, and scientific data visualization.

Research areas are slab-driven mantle flow dynamics, feedbacks between the slab and upper plate, and designing high-resolution 3D models of plate boundary systems. Besides pencil and paper for analytic problem formulation, the lab has a core Dell Linux Cluster, geosolver, shared with the Knepley Computational Science Group and b a custom-built 3D immersive virtual reality workspace in Cooke Hall.

This group studies ice sheet processes and the history of glaciation to understand arctic climate change during the Pleistocene and the Holocene.

We can calculate the half-lives of all of these elements. All the intermediate isotopes between U and Pb are highly unstable, with short half-lives. That means they don’t stay around very long, so we can take it as given that these isotopes don’t appear on Earth today except as the result of uranium decay. We can find out the normal distribution of lead isotopes by looking at a lead ore that doesn’t contain any uranium, but that formed under the same conditions and from the same source as our uranium-bearing sample.

Then any excess of Pb must be the result of the decay of U

The depositional history of Glacial Lake Missoula and features formed during multiple drainage events of the lake. Glacial Lake Missoula has been of great interest in western Montana for years, but correlation of lake-stands and drainage events to the Channeled Scablands of Washington has been based mostly on inference, not on detailed ages. I have ongoing interest in working with students on geological mapping, sedimentology, and stratigraphy of glacial deposits in the Clark Fork River drainage basin to improve understanding and correlation of these deposits.

(Lab) differentiate the types of plate boundaries and their associated features on maps and profiles and explain the processes that occur at each type of boundary.

Sometimes we need to know how old the rock really is. If you try to register for a driver’s license, simply showing that you’re obviously older than a six year old isn’t going to be enough. With rocks, the primary method of determining the precise age – known as absolute dating – is to use radiometric dating. Radiometric dating uses known rates of decay for unstable radioactive isotopes to determine the age of a specimen. Certain things, from rocks to fossils, are made of a small percentage of radioactive isotopes.

Those radioactive isotopes begin to decay as soon as the object is formed in the ground as a rock solidifies, or as a living thing dies. The isotope used for dating an object depends on the rough time scale involved.

Volume 27, Issues 5—6 , 5 December , Pages Luminescence dating: Wintle Show more https: Laboratory procedures for dating sediments have been adapted from those for pottery and new procedures have been developed as the need arises. The majority of sediment dating applications are carried out on quartz and potassium-rich feldspars and the general characteristics of the TL and OSL signals from these minerals are reviewed. For sediments some new problems were encountered, with some grains perhaps not being completely bleached at deposition.

For OSL signals there is no simple procedure for the selection of a thermally stable signal, as there had been in the case of pottery.

It was the first permanent IBM installation in the world to do scientific work Comrie’s Greenwich setup had not been permanent. In late , Eckert presented a paper on this work to the American Astronomical Society. A seemingly mundane but significant aspect of this work was the new ability to feed the result of one computation into the next and print the results of these calculations directly, thus eliminating the transcription errors that were common in astronomical and lunar tables [ 17 ].

To illustrate with a quote from Kay Antonelli, University of Pennsylvania, referring to her wartime work [ 34 ], “We did have desk calculators at that time, mechanical and driven with electric motors, that could do simple arithmetic. You’d do a multiplication and when the answer appeared, you had to write it down to reenter it into the machine to do the next calculation.

We were preparing a firing table for each gun, with maybe 1, simple trajectories. To hand-compute just one of these trajectories took 30 or 40 hours of sitting at a desk with paper and a calculator. Ben Wood and his Statistical Bureau work with IBM to develop mark-sense technology to improve the efficiency of processing standardized tests [ 9 ].

Overview[ edit ] In the scientific method , an experiment is an empirical procedure that arbitrates competing models or hypotheses. However, an experiment may also aim to answer a “what-if” question, without a specific expectation about what the experiment reveals, or to confirm prior results. If an experiment is carefully conducted, the results usually either support or disprove the hypothesis.

According to some philosophies of science , an experiment can never “prove” a hypothesis, it can only add support. On the other hand, an experiment that provides a counterexample can disprove a theory or hypothesis. An experiment must also control the possible confounding factors —any factors that would mar the accuracy or repeatability of the experiment or the ability to interpret the results.
