Ghost in the Shell: She must therefore have ended her five years of military training in , and she must have been born at least 18 years earlier, in at the least. She was turned into a cyborg at age 5, thus in The writer probably just forgot to add all the cumulative time-periods together. Saito’s flashback episode in the second season indicates that Motoko served overseas in an unofficial capacity; officially, the Japanese Self-Defence Forces avoided combat during WWIV, except for recapturing Nemuro. Ishikawa says that nobody knows who she is, only that she’s “a genius at combat” and that everyone calls her “the Major”. How she came by that rank is somewhat up in the air.

Radioactive Dating Because the radioactive half-life of a given radioisotope is not affected by temperature, physical or chemical state, or any other influence of the environment outside the nucleus save direct particle interactions with the nucleus, then radioactive samples continue to decay at a predictable rate and can be used as a clock. This makes several types of radioactive dating feasible.

For geologic dating, where the time span is on the order of the age of the earth and the methods use the clocks in the rocks , there are two main uncertainties in the dating process: What was the amount of the daughter element when the rocks were formed? Have any of the parent or daughter atoms been added or removed during the process?

Though radiocarbon dating is startlingly accurate for the most part, it has a few sizable flaws. The technology uses a series of mathematical calculations—the most recognizable of which is known as half-life—to estimate the age the organism stopped ingesting the isotope.

Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age. Scientists also use direct evidence from observations of the rock layers themselves to find the relative age of rock layers. Specific rock formations are indicative of a particular type of environment existing when the rock was being formed. For example, most limestone represents marine environments, whereas, sandstones with ripple marks might indicate a shoreline habitat or riverbed.

The study and comparison of exposed rock layers or strata in different areas of Earth led scientists in the early 19th century to propose that the rock layers could be correlated from place to place. Locally, physical characteristics of rocks can be compared and correlated. On a larger scale, even between continents, fossil evidence can help in matching rock layers.

October 17, iStock With more and more people relying on online dating to meet a partner, the act of online dating also gets studied more and more. Here are 11 revelations from recent studies. This phenomenon was observed in a study conducted at the University of Wisconsin-Madison. Women tended to claim that they were 8. Men lied by less—only two pounds—but rounded up their height by a half inch more often.

People lied the least when it came to age.

Times have changed, and that is a good thing—especially the fading-away of cruel taboos that once stigmatized women who engaged in premarital sex or bore children out of wedlock. Thing is, times change for a reason. The values question assumes that sexual mores loosen naturally from conservative to liberal. In reality, these values have ebbed and flowed throughout history, often in conjunction with prevailing sex ratios.

Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).

Unlike the radioactive isotopes discussed above, these isotopes are constantly being replenished in small amounts in one of two ways. The bottom two entries, uranium and thorium , are replenished as the long-lived uranium atoms decay. These will be discussed in the next section. The other three, Carbon , beryllium , and chlorine are produced by cosmic rays–high energy particles and photons in space–as they hit the Earth’s upper atmosphere.

Very small amounts of each of these isotopes are present in the air we breathe and the water we drink. As a result, living things, both plants and animals, ingest very small amounts of carbon , and lake and sea sediments take up small amounts of beryllium and chlorine The cosmogenic dating clocks work somewhat differently than the others.

Carbon in particular is used to date material such as bones, wood, cloth, paper, and other dead tissue from either plants or animals.

Are There Gaps in the Genesis Genealogies? Many view the original New Answers Book as an essential tool for modern discipleship. Both of these books answer such questions as: Can natural processes explain the origin of life? Can creationists be real scientists?

Oct 30,  · When it comes to dating, research shows, looks are all that matter, at least initially, something Tinder has taken full advantage of.

Cosmic age problem In the 18th century, the concept that the age of the Earth was millions, if not billions, of years began to appear. However, most scientists throughout the 19th century and into the first decades of the 20th century presumed that the universe itself was Steady State and eternal, with maybe stars coming and going but no changes occurring at the largest scale known at the time. The first scientific theories indicating that the age of the universe might be finite were the studies of thermodynamics , formalized in the mid th century.

The concept of entropy dictates that if the universe or any other closed system were infinitely old, then everything inside would be at the same temperature, and thus there would be no stars and no life. No scientific explanation for this contradiction was put forth at the time. In Albert Einstein published the theory of general relativity [16] and in constructed the first cosmological model based on his theory.

In order to remain consistent with a steady state universe, Einstein added what was later called a cosmological constant to his equations. Einstein’s model of a static universe was in addition proved unstable by Arthur Eddington. The first direct observational hint that the universe has a finite age came from the observations of ‘ recession velocities ‘, mostly by Vesto Slipher , combined with distances to the ‘ nebulae ‘ galaxies by Edwin Hubble in a work published in In addition, these galaxies were very large and very far away.

Spectra taken of these distant galaxies showed a red shift in their spectral lines presumably caused by the Doppler effect , thus indicating that these galaxies were moving away from the Earth. In addition, the farther away these galaxies seemed to be the dimmer they appeared to us the greater was their redshift, and thus the faster they seemed to be moving away. This was the first direct evidence that the universe is not static but expanding.

Islamic attitudes towards science The various Quranic injunctions and Hadith , which place values on education and emphasize the importance of acquiring knowledge, played a vital role in influencing the Muslims of this age in their search for knowledge and the development of the body of science. Greek contributions to Islamic world , Indian influence on Islamic science , Christian influences in Islam , and Chinese influences on Islamic pottery During this period, the Muslims showed a strong interest in assimilating the scientific knowledge of the civilizations that had been conquered.

Many classic works of antiquity that might otherwise have been lost were translated from Greek , Persian , Indian , Chinese , Egyptian , and Phoenician civilizations into Arabic and Persian, and later in turn translated into Turkish, Hebrew, and Latin. For a long period of time the personal physicians of the Abbasid Caliphs were often Assyrian Christians. Among the prominent centers of learning and transmission of classical wisdom were Christian colleges such as the School of Nisibis [34] and the School of Edessa , [35] the pagan University of Harran [36] [37] and the renowned hospital and medical academy of Jundishapur , which was the intellectual, theological and scientific center of the Church of the East.

An Age Difference Formula For Homos. Comments You’ve probably heard of the “half your age plus seven” rule of age differences in dating. The idea is that you divide your age by two, then add seven; that’s the youngest person you’re “allowed” to date. with someone much older than myself. I think I may withhold doing the math, even.

It’s up to us to develop the sensitivity to pick up on it. Pedantry can be the enemy of insight. This gives students the idea that there is a book somewhere with all the right answers to all of the interesting questions, and that teachers know those answers. And if one could get hold of the book, one would have everything settled. That’s so unlike the true nature of mathematics. Experience comes from bad judgement. The details are available from the author on request.

The author does hope someone will check the calculations, because he does not have a great deal of faith in his ability to carry through the details in a fault-free manner. He hopes however that the answers are qualitatively correct as stated. Every time we count pairs, we learn something from it. I’d used email since about , and it seems to me that 15 years of email is plenty for one lifetime.

It is the willingness of his teacher to listen to him. I will admit, however, that one key ingredient is caffeine.

Radioactive decay and exponential laws By Submitted by plusadmin on March 1, March In his article Light Attenuation and Exponential Laws in the last issue of Plus, Ian Garbett discussed the phenomenon of light attenuation, one of the many physical phenomena in which the exponential function crops up. In this second article he describes the phenomenon of radioactive decay, which also obeys an exponential law, and explains how this information allows us to carbon-date artefacts such as the Dead Sea Scrolls.

Radioactive Decay In the previous article, we saw that light attenuation obeys an exponential law. To show this, we needed to make one critical assumption: Exactly the same treatment can be applied to radioactive decay. However, now the “thin slice” is an interval of time, and the dependent variable is the number of radioactive atoms present, N t.

Student View Task Carbon 14 is a common form of carbon which decays over time. The half-life of Carbon 14, that is the amount of time it takes for half of the Carbon 14 to decay, is approximately years. If there is currently one microgram of Carbon 14 remaining in the preserved plant, approximately when did the plant die? IM Commentary The task requires the student to use logarithms to solve an exponential equation in the realistic context of carbon dating, important in archaeology and geology, among other places.

Note that the purpose of this task is algebraic in nature — closely related tasks exist which approach similar problems from numerical or graphical stances. The two solutions provided differ slightly in their approach in this regard. In either case, it is more appropriate to report the time since the plant has died as approximately 19, years since these measurements are never completely precise.

Alt version for sol’n 1 Since the half life of Carbon 14 is years, this means that after years there will only be 5 micrograms of Carbon 14 left in the fossilized plant:

Direct methods[ edit ] Direct data comes from vital statistics registries that track all births and deaths as well as certain changes in legal status such as marriage, divorce, and migration registration of place of residence. In developed countries with good registration systems such as the United States and much of Europe , registry statistics are the best method for estimating the number of births and deaths. A census is the other common direct method of collecting demographic data.

A census is usually conducted by a national government and attempts to enumerate every person in a country. However, in contrast to vital statistics data, which are typically collected continuously and summarized on an annual basis, censuses typically occur only every 10 years or so, and thus are not usually the best source of data on births and deaths. Analyses are conducted after a census to estimate how much over or undercounting took place.

These compare the sex ratios from the census data to those estimated from natural values and mortality data. Censuses do more than just count people.
