An Important Announcement from the ARDMS:

The main point of the debate seems to be the following: Over the past decades, several research groups of self-proclaimed creationist scientists have claimed discoveries of dinosaur bones that they have managed to date, using radiocarbon dating methods , at some age which is a lot below the ‘usual’ i. The age that these groups claim to find is usually on the order of thousands or tens of thousands of years old. The particular example you bring up is one of the most famous such cases. The claims are really quite spectacular, when taken at face value, and therefore should be examined thoroughly. In this answer, I will try to go through this story in great detail, hopefully exposing the reasons why this work is not taken seriously by scientists. The research by Miller et al. A research team from the CRSEF, or Creation Research, Science Education Foundation, led by Hugh Miller, has claimed to have dated dinosaur bones using radiocarbon methods, determining them to be no older than several dozens of thousands of years old. Let’s look at their research methodology in detail indicated by bullet points:

He received his PhD in geological sciences at the University of Southern California and has served as a Smithsonian fellow and a postdoctoral fellow at the Nuclear Regulatory Commission. He has been a faculty member at Oklahoma State University and Florida State University, and a research associate at the Florida Geological Survey, and visiting scientist at the University of Groningen, the Netherlands.

He is an associate editor of the Journal of Coastal Research. He teaches courses on energy and climate, environmental geoscience, and coastal and marine geology. He has published more than 60 papers and a large number of technical reports, and has presented or co-authored more than papers at professional meetings. He and his colleagues and students are currently involved in a multi-year project modeling the long-term history and effects of major storms on coastal environments of the northern Gulf of Mexico and SE Atlantic coasts.

Physics (from the Ancient Greek φύσις physis meaning “nature”) is the fundamental branch of primary objects of study are matter and energy. Physics is, in one sense, the oldest and most basic academic pursuit; its discoveries find applications throughout the natural sciences, since matter and energy are the basic constituents of the natural world.

Tweet What Is Physics? Briefly defined, physics is the science that tries to understand the laws of nature and the relationship between energy and matter. However, it might be more appropriate to define physics as a way of thinking rather than as a profession. The field of physics trains students to take a logical, problem-solving approach in whatever situations they might find themselves. Physics students explore concepts and methods of science that can be applied in many different professional areas and research topics.

Physics deals with everything from subatomic particles to black holes and the overall structure of the universe. Physicists use mathematical formulas to try to explain their theories and make predictions. It is a science that has attracted and confounded some of the most brilliant minds of all time: But physics is also concerned with how things work on a more tangible level.

Invariance[ edit ] A toy called the teeter-totter illustrates, in cross-section, the two aspects of time reversal invariance. When set into motion atop a pedestal rocking side to side, as in the image , the figure oscillates for a very long time. The toy is engineered to minimize friction and illustrate the reversibility of Newton’s laws of motion. However, the mechanically stable state of the toy is when the figure falls down from the pedestal into one of arbitrarily many positions.

The laws of physics are applied to fields such as engineering, communications, biology, and electronics. The development of technologies like lasers and semiconductors resulted from pioneering work in physics. Televisions, microwaves and digital cameras would not exist without breakthroughs in physics. Physics is really the study of how the world works, and, it might be considered the most fundamental of all the sciences.

The goal of physics is to develop theories that summarize the laws of nature and lead to an understanding of why things work as they do.

You seem to say that the women’s choices are either be their equals or date them — you can’t do both. I don’t really have anything to add yet, but FYI, she might not care how “in demand” she is. I guess what I mean is that there is a dichotomy from being a love interest and a co-worker. And mixing those positions can be dangerous, but perhaps sometimes it is inevitable if you are a female in an environment of mostly males.

Physics (from Ancient Greek: φυσική (ἐπιστήμη), translit. physikḗ (epistḗmē), lit. ‘knowledge of nature’, from φύσις phýsis “nature”) is the natural science that studies matter and its motion and behavior through space and time and that studies the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is.

Paul Berry After building the product for Huffington Post, and owning the product and engineering groups at AOL after we were acquired, it was clear to me there was a huge gap between what the current CMS offering gave the world and what the world needed. Five years later we are at scale, moving the needle and doing to WordPress what Airbnb did to Craigslist. Social and Centralized WordPress, Drupal, and the custom CMS solutions of the world are all independent, non-connected instances that each need to be updated individually.

At the end of the Cretaceous period, the golden age of dinosaurs, an asteroid or comet about 10 miles in diameter headed directly towards the Earth with a velocity of about 20 miles per second, over ten times faster than our speediest such large objects may have come close to the.

The discovery also reveals a pathway to treatment, scientists report today in the journal Cell Reports. The disorders affect the digestive tract and lining of the gut, where inflammation causes cramps, constipation and rectal bleeding. Fever, fatigue and appetite loss often accompany the conditions. Although there is no cure, scientists think genetics, the gut microbiome and the immune system may all play a role.

But a clear cause eluded them until Ronai and his team landed on a suspect while examining an unrelated phenomenon. Since a gene called RNF5 is a key player in these activities, the scientists suspected that disrupting its function in mice would reveal major new insights. So, a decade ago, the team created mice that lack RNF5. But the mice without RNF5 responded much more severely. They developed acute colitis with all the symptoms people have. Close to 50 percent of the animals died within a few weeks.

At the time that Darwin’s On the Origin of Species was published, the earth was “scientifically” determined to be million years old. By , it was found to be 1. In , science firmly established that the earth was 3. Finally in , it was discovered that the earth is “really” 4. In these early studies the order of sedimentary rocks and structures were used to date geologic time periods and events in a relative way. At first, the use of “key” diagnostic fossils was used to compare different areas of the geologic column.

Although there were attempts to make relative age estimates, no direct dating method was available until the twentieth century. However, before this time some very popular indirect methods were available. For example, Lord Kelvin had estimated the ages of both the Earth and the Sun based on cooling rates. The answer of 25 million years deduced by Kelvin was not received favorably by geologists. Both the physical geologists and paleontologists could point to evidence that much more time was needed to produce what they saw in the stratigraphic and fossil records.

As one answer to his critics, Kelvin produced a completely independent estimate — this time for the age of the Sun.
