Radium In The Early 1900's

On the brink of discovery there is a thrilling glow of hope and promise. The hope of a betterment of life as it is and the promise of something new and exciting. The turn of the twentieth century was this threshold of opportunity and anticipation, and a booming era for scientists and inventors alike. Between 1900 and 1920 a plethora of modern day conveniences and concepts were brought to life. Without this unique period in time civilization might have had to do without escalators, Gillette’s double edged safety razor, modern vacuum cleaners, air conditioning, the Teddy Bear, crayons, airplanes, E=mc2, automobiles, Life Savers candy, and the bra, just to name a few.1 Along with the glitter of innovation can come an unintentional (and sometimes

The age of the earth has been debated for centuries. Many people believe in evolution that it took billions of years for everything and everyone to form. Others believe that God created the earth in seven days and that the earth is young. Secular scientist and Christian scientist both use different methods for determining how old the earth is. For example, Secular scientist look and use the layers of rocks to help them, while Christian scientist uses the Bible and look at historical data from other cultures to help them. Doesn't looking at archeological data seem more accurate than looking at rocks? If the earth is truly billions of years old, then why is there little sediment on the sea floor? Or how can secular scientist explain finding soft tissue in a fossil if the earth is old? The most logical explanation is that the earth is young. Many people believe something just because people say that it is true, sometimes it is good to investigate for yourself and see if it is good for you.

Encyclopaedia Britannica also states that it is “proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old” (1998). This method of age determination is dependent upon the decay of nitrogen and radiocarbon (Carbon-14) (Encyclopaediea Britannica, 1998; Opinions of Radiocarbon Dating, 2011). Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere (Encyclopaediea Britannica, 1998; Opinions of Radiocarbon Dating, 2011) and all living things exchange the gas carbon-14 with the atmosphere surrounding them. The amount of carbon-14 exchanged into the living organism is perfectly balanced with its surroundings, but when an organism dies, they stop taking in the gas and that equilibrium is damaged. Because Carbon-14 slowly decays at a known rate called its “half-life” in a dead organism, scientists can figure out how long ago it had stopped exchanging carbon with its atmosphere. Thus, its age can be determined by measuring the amount of Carbon-14 in a sample (Hirst, 2017; Opinions of Radiocarbon Dating, 2017; Oxford Radiocarbon Accelerator Unit Research Laboratory for Archaeology, n.d.; Earthsky, 2017; Cram, 1993). With the utilisation of Radiocarbon Dating, scientists have been able to discover that Lindow

8. Is it important to know exactly how old the earth is? Why or why not?

Scientist are able to use modern instruments to accurately date these rocks by measuring radioactive decay. These rocks are approximently 1.7 billion years old, less than half the age of the earth. These black rocks tell scientist not only how old they date back but

Dating the rocks of the Grand Canyon is a scientific way to find out the age of this mysterious landmark. The age of the Earth and the Grand Canyon is a question both of a biblical interpretation and scientific investigation. It can be viewed by an old earth creationist and young earth creationist. The two creationists have a difference of opinion concerning the formation and age of the Grand Canyon rocks.

In 1947 Clair "Pat" Patterson began to calculate the age of the Earth by the request of Harrison Brown at the University of Chicago. The age of the Earth was always questionable to historians before Pat Patterson. In 1650 James Usher Archbishop of Ireland accepted biblical views as authoritative and used events from the old testament to calculate the age of the Earth. His calculations gave him the result of Saturday October 22, 4004 B.C. at six o' clock P.M. Scientists after that began to try and measure the sediments of rock in the Earth but their calculations varied too widely from three million to fifteen billion years. It was then discovered that by calculating the amount of lead in meteorites you will be able to see exactly how old the Earth really is.

What I mean is that I believe when Ellen White says 6000 years, it is pretty close to 6,000 years. Clearly, it is not exactly 6,000 years as the date of 4,004 BC which this theory was originally based on clearly puts us over 6,000 years at this point. However, plus or minus 1,000 years seems to be in the concept of near when concerned with the broad concept that Ellen White says that the earth is about 6,000 years old. I do not ascribe to the earth being 9,000 or 10,000 years old. When Ellen White definitely says 6,000 years several times I do believe it is close around this general timeframe put

Just like one can tell that age of a person by thing such as their height, weight, hair, and skin, scientists should be able to see signs of wear on the earth. “Every year, water and wind erode about 20 billion tons of dirt and rock and debris from the continents and deposit them on the sea floor. Yet the average thickness of all of these sediments globally over the whole seafloor is not even 1,300 feet.” (The New Answers Book 4 113) This disproves the theory of evolution since there is so little settlement on the sea

In 1820 another French man named James Fourier took the next step in estimating the Earth’s age. He accounted for the fact that the Earth is still hot in its core and using mathematical techniques that he developed and we still use today for time-varying phenomena, came up with a number too staggering foe him to write down. He did however leave us his equations and it is easy to plug in the same numbers and get the answer that he could not say, which comes out to be 100 million years. (Gribbin, 16)

The Curiosity rover itself will age date the rock in order to determine if water was ever present on mars, how many years ago water was in the basin, the age of the rocks. The first form of age dating involves identifying the age of the rock itself, and the second is how recently the rock has been exposed at the surface. The first type of age process represents how long ago that Mars had an earth-like climate, and the second type of age process refers to how long the rock may have been impacted by cratering environments and volcanic activity. In the past crater counting usually helped to determine the age of the surface of the mars. The more surface craters there were, the oldest the planet was thought to be.

Before the discovery of radiometric methods to determine the age of the Earth, the first few attempts were off by thousands of millions

This method is used to determine the exact age of fossils, artifacts and the earth. This involves, examining several strata of the crust of the earth to show the time intervals of one layer of rock to another layer as well as use the layering principle to confirm the series of cultures.

Curie thus began studying uranium radiation and made it her doctoral thesis. With the aid of an electrometer built by Pierre, Marie measured the strength of the radiation emitted form uranium compounds and found it proportional to the uranium content, constant over a long period of time and influenced by external conditions. She detected a similar immutable radiation in the compounds of thorium. While checking these results, she made the discovery that uranium pitchblende and the mineral chalcolite emitted four times as much radiation as their uranium content. She realized that unknown elements, even more radioactive then uranium must be present.

This is what led Curie to take Becquerel’s work a few steps further and conduct her own experiments on uranium rays. She discovered that the rays were constant no matter what form or condition of the uranium. She theorized the rays came from the atomic structure. This idea was revolutionary and created its own field in science, known as the atomic physics, this is when Marie coined the word “radioactivity” to describe the phenomena. Even when they had their first daughter Irene in 1897 there work did not slow. Pierre then stopped his own studies to help Marie with her new discovery of radioactivity. In 1898 they discovered a new radioactive element. They named it polonium after Marie’s native country, Poland. They detected the presence of another radioactive element and called this radium. In 1902 they had extracted pure radium to prove its existence as a unique chemical element.
