Copper at 80 cents a pound. Can we crack the code to build the world of the future? Far from prying eyes, the ground erupts; heavy equipment moving millions of tons of earth in search of something: I’ve managed to talk my way into this hidden lair. Boy, I hope I can talk my way out. This area, here, has been backfilled. They tell me that so much money flows out of this place, it’s like a gold mine.

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.

Consider also the most popular explanation offered for the photo right , that a concretion formed around an s-era hammer as minerals precipitated out of the surrounding limestone. From Adam until Real Science Radio , in only generations! Another paper, in the American Journal of Physical Anthropology Eugenie Scott ‘s own field on High mitochondrial mutation rates , shows that one mitochondrial DNA mutation occurs every other generation, which, as creationists point out , indicates that mtEve would have lived about generations ago.
That’s not so old! As our List of Not So Old Things this web page reveals, by a kneejerk reaction evolutionary scientists assign ages of tens or hundreds of thousands of years or at least just long enough to contradict Moses’ chronology in Genesis. However, with closer study, routinely, more and more old ages get revised downward to fit the world’s growing scientific knowledge. Consistent with this observation, the May issue of National Geographic quotes the U. Forest Service’s scientist at Mount St.
Helens, Peter Frenzen, describing the canyon on the north side of the volcano. But this was cut in less than a decade. Helens, the volcanic mount, is only about 4, years old! Secular scientists default to knee-jerk, older-than-Bible-age dates.

Apparent motion — The observed motion of a heavenly body across the celestial sphere, assuming the Earth is at the sphere’s center and is standing still. Atlas — An early liquid-fueled rocket, used by US astronauts and still in use for unmanned launches. Because of its lightweight construction it uses no staging, but only drops two of its engines. Azimuth and elevation — Two angles which give the direction of a surveyor’s telescope theodolite.
Azimuth is the rotation angle of the telescope around a vertical axis, measured counterclockwise from above from due north, a direction whose azimuth is zero degrees.
On the first page of the lab packet, ask students to define the following terms in their own words: isotopes, mass number, and atomic number. At the end of the lesson, students will be asked to reflect upon and revise, if needed, these definitions.

It doesn’t matter if it’s designed not to do that, it doesn’t matter if it’s not fissile enough to be used for an atomic bomb, it doesn’t matter if it hasn’t got enough material for critical mass, it’s gonna blow. The explosives are directed inward in order to generate the necessary chain reaction. High precision engineering is required to get everything to come together properly; if things are off by even milliseconds, the yield will be dramatically reduced and it may fizzle entirely.
In fact, partial detonation of the explosives will disable the nuclear weapon but probably contaminate the area with radiation.. Blunt force will not set off a nuclear weapon either, no matter how hard. In fact, here’s a film produced by the US Air Force back in showing nuclear weapons being purposely dropped out of planes, set on fire, and otherwise subjected to movie-of-the-week hijinks to demonstrate that rough treatment of nuclear weapons does not result in said weapons detonating.

There are lots of ways to guesstimate ages, and geologists knew the earth was old a long time ago and I might add that they were mostly Christian creationist geologists. But they didn’t know how old. Radiometric dating actually allows the measurement of absolute ages, and so it is deadly to the argument that the earth cannot be more than 10, years old. Radiometric methods measure the time elapsed since the particular radiometric clock was reset. Radiocarbon dating, which is probably best known in the general public, works only on things that were once alive and are now dead.
It measures the time elapsed since death, but is limited in scale to no more than about 50, years ago. Generally applied to igneous rocks those of volcanic origin , they measure the time since the molten rock solidified. If that happens to be longer than 10, years, then the idea of a young-Earth is called into question. If that happens to be billions of years, then the young-Earth is in big trouble.
As of January, , The oldest rocks found on earth are 4.

Most absolute age determinations in geology rely on radiometric methods. Earth is billions of years old. The most useful methods for measuring the ages of geologic materials make use of radioactive parent isotopes and their stable daughter products , as preserved in rocks, minerals, or other geologic materials. An isotope is a particular type of atom of a chemical element, which differs from other isotopes of that element in the number of neutrons it has in its nucleus. By definition, all atoms of a given element have the same number of protons.

Galena would have been noticed by anyone looking for metals in ancient times. Galena generally contains silver, sometimes in significant quantities. Doug Stewart Silver has been in use since prehistoric times. We do not know who discovered it, although the discovery would almost certainly have been of native silver. Nuggets of native silver metal can be found in minerals and sometimes in rivers; but they are rare.
The others were gold , copper , lead and iron.
Hunting the Elements
Presence of absorbers necessitates corrections to this law. ION An atomic or molecular particle having a net electric charge. Included are particle-induced gamma and x-ray emission, Rutherford backscattering spectroscopy, nuclear microprobes and other methods of nuclear reaction analysis. Also known as ion concentration. In surface chemistry, if the adsorption of one or several ionic species is accompanied by the simultaneous desorption displacement of an equivalent amount of one or more other ionic species, this process is called ion exchange.
May 24, · Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons. Given information about an element, find the mass and name of an isotope. Give evidence to support or dispute: “In nature, the chance of finding one isotope of an element is .
If you put in the effort to learn the material you will do well. Your grade will be based on the following categories. This will clearly indicate whether it was excused or unexcused. If you come to class without one you will be asked to go to the office to obtain it. If you miss class, and it is an excused absence, then you may make up the work you missed. You must see me before class starts or after it has ended and ask for the work. It is your responsibility to find out what you missed and to do it.
You must complete the work no later than the due date plus the number of days absent or the usual late penalties will apply.
