- Kelvin - 316 words
Kelvin "Thomsons view on the recent age of the world have been for some time one of my sorest troubles, (pg. 107)" This quote is used to collaborate the authors idea that Darwin was deeply opposed to Kelvins calculations about the ago of the earth. The author further backs up this idea by using another quote in which Darwin calls Kelvin an "odious spectre, (pg. 107)." It is then stated that Darwin did eventually compromise with Kelvins calculations. Gould uses a quote from the last edition of the Origin to make the statement more concrete. Darwins reasons for compromising with Kelvins theory are then explained in the following paragraphs. Gould discusses Darwins distress as his leading suppo ...

- A Vogadro Was Born On June 9, 1776 In Turin, Italy He Began His Career In 1796 By Obtaining A Doctorate In Law And Practicing - 596 words
A vogadro was born on June 9, 1776 in Turin, Italy. He began his career in 1796 by obtaining a doctorate in law and practicing as a lawyer for three years after. In 1800, he began to take private lessons in mathematics and physics and decided to make the natural sciences his profession. He was appointed as a demonstrator at the Academy of Turin in1806 and the Professor of Natural Philosophy at the College of Vercelli in 1809, and in 1820, he was appointed the professor of mathematical physics. He was a physics professor but he also experimented in chemistry using mathematics to base most of his findings. Avogadro is well known for his hypothesis known as Avogadro's Law. His law states that a ...

- Cryogenics And The Future - 1,202 words
Cryogenics And The Future Cryogenics is a study that is of great importance to the human race and has been a major project for engineers for the last 100 years. Cryogenics, which is derived from the Greek word kryos meaning Icy Cold, is the study of matter at low temperatures. However low is not even the right word for the temperatures involved in cryogenics, seeing as the highest temperature dealt with in cryogenics is 100 (C (-148 (F) and the lowest temperature used, is the unattainable temperature -273.15 (C (-459.67 (F). Also, when speaking of cryogenics, the terms Celsius and Fahrenheit are rarely used. Instead scientists use a different temperature measurement scale called the Kelvin ( ...

- Fusion - 1,323 words
... eating, and the onset of nuclear fusion. The situation in star formation differs in one respect: after gravitational collapse ceases and star begins to expand again due to heat from exoergic nuclear fusion reactions, the expansion is arrested by the gravity force associated with the enormous mass of the star. In a star a state of equilibrium in both size and temperature is achieved. In ICF, by contrast, complete disassembly of fuel occurs. The fusion reaction least difficult to achieve combines a deuteron (the nucleus of the deuterium atom) with a triton (the nucleus of a tritium atom). Both nuclei are isotopes of the hydrogen nucleus and contain a single unit of positive electric charge ...

- How A Star Is Born - 1,174 words
How A Star Is Born Birth of Stars Since my entire thesis for this paper is about how a star is born, I guess the first thing I should start out with is by telling you exactly what a star is. Stars are self-luminous gaseous spheres. They shine by generating their own energy and radiating it off into space. The stars' fuel for energy generation is the stuff they are made of -- hydrogen, helium, carbon, etc. -- which they burn by converting these elements into heavier elements. Nuclear fusion occurs, which is when the nuclei of atoms fuse into nuclei of heavier atoms. The energy given off by a star through nuclear burning heats its interior to many millions and, even in some cases to Pleiades S ...

- Influences On Normal Physical - 1,230 words
Influences On Normal Physical Physical growth in early childhood is partially easy to measure and gives an idea of how children normally develop during this period. The average child in North America is less than three feet tall at two years of age. Physical growth contains no discrete stages, plateaus, or qualitative changes. Large differences may develop between individual children and among groups of children. Sometimes these differences affect the psychological development of young children. These differences create a nice variety among children. Most dimensions of growth are influenced by the child's genetic background. Also, races and ethnic backgrounds around the world differ in growt ...

- Jupiter Moons - 1,332 words
Jupiter Moons Jupiter, the largest of the Jovian planets, reigns supreme throughout the solar system. Named after the Roman god Jove, the ruler of Olympus; "Jupiter is the fifth planet from the sun and is also the largest planet in the Earth's solar system. It is 318 times moremassive than Earth and is two thirds of the planetary mass in the solar system. Jupiter's surface, unlike earth, is gaseous and not a solid. It is about 90% hydrogen and 10% helium with traces of methane, ammonia, water and rock. Jupiter's interior is very similar to the Sun's interior but with a far lower temperature."(Columbia) However, it is still unknown for certain, but Jupiter is believed to have a core of liquid ...

- Radon - 569 words
Radon Radon is an element that is on the periodic table of elements. It is a member of the family called the noble gases, which is group number 18. Radon is a gas. It is a gas at 298 k. it is the heaviest known mononuclear gas at that temperature. Radon is also colorless. When it is cooled below the freezing point, radon exhibits a brilliant phosphorescence, which becomes yellow as the temperature is lowered. At the temperature of liquid air it is sort of an orangish-red. The noble gases can be found on the very right side of the periodic table of elements. Radon has been around for quite some time. Radon comes from the element radium, which is derived from the element uranium. After radium ...

- Relativity Theory - 1,755 words
Relativity Theory The theory of relativity was introduced by Albert Einstein around the early nineteen hundereds. It is a theory which enables the human mind to understand the possible actions of the universe. The theory is divided into two parts, the special, and the general. In each part, there is a certain limit to which it explains and helps to comprehend. In the special, Einstein explains ways of understanding the atom and other small objects, while the general is designed for the study of large objects, such as planets. The theory of relativity having being created, succeeded the two hundred year old mechanics of Isaac Newton, thus showing Einstein as more of a futuristic thinker and a ...

- Super Conductivity Is A Natural Phenomenon In Which Certain Materials Such As Metals, Alloys, And Ceramics, Can Conduct Elect - 519 words
Super conductivity is a natural phenomenon in which certain materials such as metals, alloys, and ceramics, can conduct electricity without resistance. These materials are what we call superconductors. In a superconductor, once the flow of electrons begins, it essentially goes on forever, making it an important material to humans. Superconductivity was discovered by a Dutch scientist by the name of Heike Kamerlingh Onnes in 1911. While researching properties of materials at absolute zero, this man found out that certain materials lost its resistance to the flow of electrons. For years to come, his discovery was at the head of theoretical interest. The only problem though, was that people at ...

- Superconductivity - 1,518 words
SUPERCONDUCTIVITY The definition of superconductivity. Superconductivity is a phenomenon displayed by certain conductors that show no resistance to the flow of electric current. Conductors are materials in which the electron current goes through. There are 4 different kinds of conductors. Insulators, like glass or wood, have a very high resistance while semi-conductors, such as silicon, have a medium resistance. Conductors, like copper and other metals, have very low resistance, and superconductors, comprised of certain metals such as mercury and ceramics such as lanthanum-barium-copper-oxide, have no resistance. Resistance is an obstacle in the flow of electricity. Superconductors also have ...

- The Case For The Existence Of God - 3,155 words
The Case For The Existence of God by Bert Thompson, Ph.D. Introduction Either God exists or He doesn't. There is no middle ground. Any attempt to remain neutral in relation to God's existence is automatically synonymous with unbelief. It is far from a "moot" question, for if God does exist, then nothing else really matters; if He does not exist, then nothing really matters at all. If He does exist, then there is an eternal heaven to be gained (Hebrews 11:16) and an eternal Hell to be avoided (Revelation 21:8). The question for God's existence is an extremely important one. One might wonder why it is necessary to present evidence for the existence of God. As Edward Thomson so beautifully stat ...

... approximately every 24 hours on its axis. From where do we get our month? It comes from the moon circling the earth once approximately every 28 days. From where does our year come? It takes the earth approximately 365.26 days to go around the sun. `But where do we get our week?' There is no purely natural explanation for the week. The explanation, instead, is found in Exodus 20:11 (cf., Exodus 31:17): "for in six days Jehovah made heaven and earth, the sea, and all that in them is, and rested on the seventh day...." The week is an entirely universal phenomenon. Yet there is no purely natural explanation for it. Little wonder Isaiah wrote (40:26): "Lift up your eyes on high, and behold wh ...

- The Solar System - 1,185 words
The Solar System The Solar System consists of the Sun, the nine planets and their satellites; the comets, asteroids, meteoroids, and interplanetary dust and gas. It is composed of two systems, the inner solar system and the outer solar system. The inner solar system contains the Sun, Mercury, Venus, Earth and Mars. The outer solar system contains Jupiter, Saturn, Uranus, Neptune and Pluto. The inner planets are relatively small and made primarily of rock and iron. The asteroids orbit the sun in a belt beyond the orbit of Mars, tumbling and sometimes colliding with one another. Made mostly of rock and iron, the asteroids may be the remnants of a planet that never formed. The outer planets, wi ...

- The Universe - 1,282 words
The Universe It is always a mystery about how the universe began, whether if and when it will end. Astronomers construct hypotheses called cosmological models that try to find the answer. There are two types of models: Big Bang and Steady State. However, through many observational evidences, the Big Bang theory can best explain the creation of the universe. The Big Bang model postulates that about 15 to 20 billion years ago, the universe violently exploded into being, in an event called the Big Bang. Before the Big Bang, all of the matter and radiation of our present universe were packed together in the primeval fireball--an extremely hot dense state from which the universe rapidly expanded. ...
