Fermented Soy Fermented soy is often found in Asian cuisine. You can find it in miso, soy sauce, and tempeh. The fermenting process converts minerals into forms that are more easily absorbed by the body. What is it Supposed to Do? Researchers are also examining whether eating soy foods can help prevent hormone-related cancers, such as breast, prostate, and uterine cancer. Soy sauce also contains an antihypertensive component. According to WebMD, the live bacteria in yogurt, probiotics, have many benefits depending on the strain. These benefits include antimutagenic effects, anticarcinogenic properties, improvement in lactose metabolism, reduction in serum cholesterol, and immune system stimulation. Honey Enzymes Enzymes are found in raw honey.
The remedies were few and hardly efficacious, the mercury inunctions and suffumigations that people endured were painful and many patients died of mercury poisoning. Only the Spanish influenza epidemic of accounted for more loss of duty during that war. Up until the early 20th century it was believed that syphilis had been brought from America and the New World to the Old World by Christopher Columbus in In a new hypothesis was put forward, that syphilis had previously existed in the Old World before Columbus.
The soldiers were mostly mercenaries — Flemish, Gascon, Swiss, Italian, and Spanish — and were accompanied by camp followers including cooks, medical attendants and prostitutes.
Potassium decays with a half-life of million years, meaning that half of the 40 K atoms are gone after that span of time. Its decay yields argon and calcium in a ratio of 11 to Its decay yields argon and calcium in a ratio of 11 to
Primary source references As a preface to this document, I want to point out that it is a shame that we have to continue to refute the same arguments that evolutionists keep bringing up over and over again in their attempts to argue against the fact of creation, which fact has been well established since the day the earth was created ex nihilo several thousand years ago.
It is also a shame that the masses have bought all this based on some circular reasoning about fossils, where fossils tend to be found buried, similarities between various life forms, the presence of certain decay products in rocks, and other inherently speculative arguments about the past, based on phenomena that exist in the present.
If I hope to accomplish anything, it will be to simply encourage critical thinking. One must get past the arguments ad populum that its popularity counts for something , ad hominem that if you attack the person making the argument, this counts for something , and especially ad baculum that there are people who have the clout to decree it as true , to ask the key questions and challenge the unsubstantiated assumptions and thinking of those who would hold to the evolution position.
Today there are an increasing number of anti-creationist authors who are producing books and periodicals that make this relatively brief presentation insufficient to deal with all the points in dispute. Those defending creation today who don’t have the time to devote their life’s study to gaining expertise in all fields of inquiry must principally be prepared to think critically, logically, and challenge unsubstantiated assumptions made by these people.
They must also keep a level head in the face of some vicious attacks and diatribes that will be directed against them, as is advised in the scriptures 1 Peter 3: By way of definitions, I want to point out that when I speak of “evolution,” I am referring to the popular contemporary use of the word, which in a nutshell is the belief that all life forms are related by ancestry, and that the first life form occurred spontaneously, all due to completely natural processes. When I speak of “creation,” I am referring to the inherently obvious fact that the origin of all life forms can be attributed to a creator who purposefully created them with planning and intent, and the documented fact that this occurred over the course of a week’s time several thousand years ago.
This document is not a scientific thesis, but an apologetic intended to be submitted and defended by me in an interactive, online electronic forum.
Potassium-40 is useful for dating very old fossils because..?
A fever is any body temperature elevation over The body maintains stability within this range by balancing the heat produced by the metabolism with the heat lost to the environment. The “thermostat” that controls this process is located in the hypothalamus, a small structure located deep within the brain. The nervous system constantly relays information about the body’s temperature to the thermostat, which in turn activates different physical responses designed to cool or warm the body, depending on the circumstances.
A fever occurs when the thermostat resets at a higher temperature, primarily in response to an infection. To reach the higher temperature, the body moves blood to the warmer interior, increases the metabolic rate, and induces shivering.
The isotope potassium decays into argon at a predictable rate. By measuring the ratio of the two present in a rock, we can work out how long it is since the rock was formed from magma.

Discovery of Potassium Dr. Doug Stewart In English chemist Sir Humphry Davy discovered that chemical bonding was electrical in nature and that he could use electricity to split substances into their basic building blocks — the chemical elements.
In he isolated potassium for the first time at the Royal Institution, London. He electrolyzed dried potassium hydroxide potash which he had very slightly moistened by exposing it to the moist air in his laboratory. The electrolysis was powered by the combined output of three large batteries he had built.
For this example, the term half time might be used instead of “half life”, but they mean the same thing. It varies depending on the atom type and isotope , and is usually determined experimentally. See List of nuclides. The half life of a species is the time it takes for the concentration of the substance to fall to half of its initial value.
The common potassium-argon dating process makes use of the decay of 40 K to 40 Ar, even though much more of the 40 K decays to 40 Ca. The reason is that 40 Ca is common in minerals, and sorting out what fraction of that calcium came from potassium decay is not practical.
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? Just how reliable are these dates? As with any experimental procedure in any field of science, these measurements are subject to certain “glitches” and “anomalies,” as noted in the literature.
Radiometric Dating and the Geological Time Scale
Wujing Zongyao , Four Great Inventions , List of Chinese inventions , and Heilongjiang hand cannon Based on a 9th-century Taoist text, the invention of gunpowder by Chinese alchemists was likely an accidental byproduct from experiments seeking to create elixir of life. In the following centuries various gunpowder weapons such as bombs , fire lances , and the gun appeared in China.
A slow match for flame throwing mechanisms using the siphon principle and for fireworks and rockets is mentioned. However by the Song court was producing hundreds of thousands of fire arrows for their garrisons. The first proto-guns, known as “fire lances”, were first recorded to have been used at the siege of De’an in by Song forces against the Jin. By some fire lances were firing wads of bullets.
Potassium 40 is a radioisotope that can be found in trace amounts in natural potassium, is at the origin of more than half of the human body activity: undergoing between 4 .
Etymology[ edit ] Potassium nitrate, because of its early and global use and production, has many names. Hebrew and Egyptian words for it had the consonants n-t-r, indicating likely cognation in the Greek nitron, which was Latinised to nitrum or nitrium. Thence Old French had niter and Middle English nitre. By the 15th century, Europeans referred to it as saltpeter  and later as nitrate of potash, as the chemistry of the compound was more fully understood.
The Arabs called it “Chinese snow” Arabic: Potassium nitrate is moderately soluble in water, but its solubility increases with temperature see infobox. The aqueous solution is almost neutral, exhibiting pH 6. It is not very hygroscopic , absorbing about 0. It is insoluble in alcohol and is not poisonous; it can react explosively with reducing agents, but it is not explosive on its own.
In this book, al-Rammah describes first the purification of barud crude saltpeter mineral by boiling it with minimal water and using only the hot solution, then the use of potassium carbonate in the form of wood ashes to remove calcium and magnesium by precipitation of their carbonates from this solution, leaving a solution of purified potassium nitrate, which could then be dried. The terminology used by al-Rammah indicated a Chinese origin for the gunpowder weapons about which he wrote.
From caves[ edit ] A major natural source of potassium nitrate was the deposits crystallizing from cave walls and the accumulations of bat guano in caves.

Potassium—argon dating[ edit ] Decay scheme Potassium is especially important in potassium—argon K—Ar dating. Argon is a gas that does not ordinarily combine with other elements. So, when a mineral forms — whether from molten rock , or from substances dissolved in water — it will be initially argon-free, even if there is some argon in the liquid.
However, if the mineral contains any potassium, then decay of the 40K isotope present will create fresh argon that will remain locked up in the mineral. Since the rate at which this conversion occurs is known, it is possible to determine the elapsed time since the mineral formed by measuring the ratio of 40K and 40Ar atoms contained in it. The argon found in Earth’s atmosphere is
How does Carbon Dating Work? Potassium dating (half-life: billion years), Uranium dating (half life: billion years), etc. There are calibration charts as well to account for the change in the amount of carbon content in the atmosphere over the years to diminish errors. Although carbon dating technique has its.
