Sanders stood his ground. He later said that Mrs. Clinton should apologize for saying his campaign had lied. We took a look at the numbers. First of all, Mrs. When it comes to people who work in the oil and gas industry, Mrs. Clinton has indeed raised more money than Mr.
Maximizes ability to distinguish between sp2 and sp3 carbon. C KLL acquisition conditions: Interpretation of XPS Spectra The C1s spectrum from a sample with high concentration of sp2 carbon will have a broad, asymmetric tail towards higher binding energy. One or more satellite features, several eV from the main C1s peak, will also be observed in samples with high sp2 concentration.
That is, we can get both parent and daughter elements from the magma inherited into minerals that crystallize out of lava, making these minerals look old.
Xenon reacts with fluorine to form numerous xenon fluorides according to the following equations: However, due to the high radioactivity and short half-life of radon isotopes , only a few fluorides and oxides of radon have been formed in practice. Under extreme conditions, krypton reacts with fluorine to form KrF2 according to the following equation: These are compounds such as ArF and KrF that are stable only when in an excited electronic state ; some of them find application in excimer lasers.
In addition to the compounds where a noble gas atom is involved in a covalent bond , noble gases also form non-covalent compounds. The clathrates , first described in ,  consist of a noble gas atom trapped within cavities of crystal lattices of certain organic and inorganic substances. The essential condition for their formation is that the guest noble gas atoms must be of appropriate size to fit in the cavities of the host crystal lattice.
For instance, argon, krypton, and xenon form clathrates with hydroquinone , but helium and neon do not because they are too small or insufficiently polarizable to be retained. Bonding in such compounds can be explained using a three-center four-electron bond model. For example, bonding in XeF 2 is described by a set of three molecular orbitals MOs derived from p-orbitals on each atom.
Bonding results from the combination of a filled p-orbital from Xe with one half-filled p-orbital from each F atom, resulting in a filled bonding orbital, a filled non-bonding orbital, and an empty antibonding orbital. The highest occupied molecular orbital is localized on the two terminal atoms. This represents a localization of charge which is facilitated by the high electronegativity of fluorine.
Public Opinion Introduction The television, newspapers, and textbooks commonly proclaim, as though it were proven fact, that the earth is 4 to 5 billion years old. What is not commonly taught is how the scientists determined that age. What assumptions did they make? What evidence did they use?
F Perhaps not all of these processes have been uniform.
Share by Mail The question of the meaning and proper interpretation of the early chapters of Genesis is one of the most heated subjects in Christendom today. Few other topics have evoked such polarised opinion and division. The diversity of views on Genesis, even among the most learned of exegetes and scholars, is staggering. While one extreme insists that the days of Genesis must strictly be interpreted as seven consecutive hour periods thus rendering the earth very young indeed — in the order of thousands, and not millions or billions, of years old , at the other extreme lies the notion that the early chapters of Genesis are devoid of any historical content at all.
There is a plethora of competing views which reside in the middle of those polar extremes: In this article, I attempt to show that, while it is possible to interpret the book of Genesis in light of a young earth, there is no Biblical mandate for this conclusion: That is to say, Genesis could be interpreted in that manner, but it does not have to be.
And, as a scientist, the arguments for an ancient earth seem to be very compelling needless to say, when it comes to Darwinian evolution, it is a very different story. Having shown that Genesis does not require that one read it as conveying a young earth, I hope that readers will be convinced that we can thus read and understand the science on its own terms as well. It seems to me that there are three major subtopics which an article of this nature must address. The proper interpretation of Genesis One.

A younger Sheldon in Sheldon at age 9, in “I’m not crazy, my mother had me tested. Sheldon Lee  Cooper  , B. Originally from East Texas , Sheldon started college at the age of 11, receiving his first Ph. Sheldon was involved in numerous experiments as a wunderkind, such as his plan to provide free electricity for his hometown by building a nuclear reactor – a plan stopped by government pen pushers claiming it’s illegal to store yellowcake uranium in a garden shed.
Proudly geeky, he has no qualms about speaking Klingon , wearing vintage t-shirts sporting superhero logos, or spouting various historical and cultural anecdotes e. While he might claim to be the perfect human specimen, Sheldon does have his faults. Sheldon is characterized by a strict adherence to routine and hygiene; an overly intellectual personality; a tenuous understanding of irony, sarcasm and humor; and a general lack of humility or empathy, the former of which is demonstrated in the fact that he has no problem voicing to his peers his admiration for his superior intellect.
These qualities, along with his penchant for pranks , are his character’s main source of humor. He is often considered to be the most iconic character of the show. He has an older brother named George Jr. Meanwhile, he was forced to watch football by his father.

Shop Now Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth. Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old. With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.
Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.
Pin jacks on the lower front panel provided external input to the db meter, external modulation and sweep synchronized voltage.
His calculations did not account for heat produced via radioactive decay a process then unknown to science or, more significantly, convection inside the Earth, which allows more heat to escape from the interior to warm rocks near the surface. For biologists, even million years seemed much too short to be plausible. In Darwin’s theory of evolution , the process of random heritable variation with cumulative selection requires great durations of time.
According to modern biology, the total evolutionary history from the beginning of life to today has taken place since 3. Huxley , attacked Thomson’s calculations, suggesting they appeared precise in themselves but were based on faulty assumptions. The physicist Hermann von Helmholtz in and astronomer Simon Newcomb in contributed their own calculations of 22 and 18 million years respectively to the debate: However, they assumed that the Sun was only glowing from the heat of its gravitational contraction.
The process of solar nuclear fusion was not yet known to science.

May 17, Michael Rogalski For 60 years, American drivers unknowingly poisoned themselves by pumping leaded gasoline into their tanks. Here is the lifelong saga of Clair Patterson—a scientist who helped build the atomic bomb and discovered the true age of the Earth—and how he took on a billion-dollar industry to save humanity from itself.
He was queasy, not out of his mind. But on a mild October night in , shortly after Dymock groggily tucked himself into bed, something within him snapped. Like a man possessed, Dymock rose, fumbled through the dark, opened his window, and leapt into his garden. Hours later, a passerby discovered him lying in the dirt, still breathing.
He was hurried to a hospital. Many of his coworkers were acting erratically too. One night that same week, he had arrived home feeling ill. By sunrise, he was thrashing at phantoms. His family rang the police for help—it would take four men to wrap him in a straitjacket. A few miles away, Herbert Fuson was also losing his grip on reality. He’d be restrained in a straitjacket, too. The most troubling case, however, belonged to Ernest Oelgert.

Updated 8 January c Introduction In a related article on geologic ages Ages , we presented a chart with the various geologic eras and their ages. In a separate article Radiometric dating , we sketched in some technical detail how these dates are calculated using radiometric dating techniques. As we pointed out in these two articles, radiometric dates are based on known rates of radioactivity, a phenomenon that is rooted in fundamental laws of physics and follows simple mathematical formulas.
Dating schemes based on rates of radioactivity have been refined and scrutinized for several decades. The latest high-tech equipment permits reliable results to be obtained even with microscopic samples. Radiometric dating is self-checking, because the data after certain preliminary calculations are made are fitted to a straight line an “isochron” by means of standard linear regression methods of statistics.
The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date. Technical details on how these dates are calculated are given in Radiometric dating. Here is one example of an isochron, based on measurements of basaltic meteorites in this case the resulting date is 4. Reliability of radiometric dating So, are radiometric methods foolproof?

Some of the test and monitoring equipment for the military was the best that could be produced at the time and no expense was spared in its construction. At the budget-built end, there were the countless test-gadgets intended for radio repairmen or radio hobbyists that might seem to barely be able to perform the intended task but clever designs sometimes resulted in very useful test instruments.
Biddle of Philadelphia imported these instruments and each box has his tag attached.
Tilton moved to a virgin lab, and when he tried again, his numbers emerged spotless.
How Old Is The Earth? How old is the Earth? Scientists think that the Earth is 4. Coincidentally, this is the same age as the rest of the planets in the Solar System, as well as the Sun. In the early Solar System, all of the planets formed in the solar nebula; the remnants left over from the formation of the Sun. Small particles of dust collected together into larger and larger objects — pebbles, rocks, boulders, etc — until there were many planetoids in the Solar System.
These planetoids collided together and eventually enough came together to become Earth-sized. At some point in the early history of Earth, a planetoid the size of Mars crashed into our planet. The resulting collision sent debris into orbit that eventually became the Moon. How do scientists know Earth is 4. The oldest rocks ever found on Earth are 4. Scientists assume that all the material in the Solar System formed at the same time. Various chemicals, and specifically radioactive isotopes were formed together.
