- 2411: Human Cloning Isn't as Scary as It Sounds
- ... takes a fertility drug so that she can influence when she has childrenor even how many. Why, then, would we object if a woman decides to give birth to a child who is, in effect, a non-contemporaneous identical twin of someone else? By arguing against a ban, I am not claiming that there are no serious ethical concerns to the manipulation of human genes. Indeed there are. For example ...
- 2412: The Big Bang and The Steady State Model
- ... average density of matter forever. There are observational evidences found that can prove the Big Bang model is more reasonable than the Steady State model. First, the redshifts of distant galaxies. Redshift is a Doppler effect which states that if a galaxy is moving away, the spectral line of that galaxy observed will have a shift to the red end. The faster the galaxy moves, the more shift it has. If ...
- 2413: Cryogenics and the Future
- ... a "thermodynamic process in which the temperature of a gas is expanded without adding or extracting heat from the gas or the surrounding system"(Vance 26). At the same time Pictet used the "Joule-Thompson Effect," a thermodynamic process that states that the "temperature of a fluid is reduced in a process involving expansion below a certain temperature and pressure"(McClintock 4). After Cailletet and Pictet, a third method, known as ...
- 2414: The Cosmos: Creation
- ... the corresponding atoms in the lab. Furthermore he found that the farther away the galaxy was the more it was shifted toward the red end of the spectrum. Hubble attributed this shift to the doppler effect. Hubble saw this and concluded that all galaxies are rushing away from us and the universe is expanding as a whole. Modern equipment has observed and verified this so-called Hubble expansion exists throughout the ...
- 2415: Black Holes
- ... exist. At the singularity, the laws of physics break down, including Einstein's Theory of General Relativity. This is known as Quantum Gravity. In this realm, space and time are broken apart and cause and effect cannot be unraveled. Even today, there is no satisfactory theory for what happens at and beyond the rim of the singularity. A rotating black hole has an interesting feature, called a Cauchy horizon, contained in ...
- 2416: Genetics Engineering
- ... soon define. Mankind may get so intelligent that we forget all of our animal instincts. As with all things, there can be a good side and a bad side. Genetic engineering will have a major effect on our future society. There will be many social changes. It is hard enough today to know whether someone has breast implants or if there hair is real. We might have to guess if a ...
- 2417: Galileo and Newton
- ... they are mostly conceptual views. Newton would have to support Democritus for initiating the atomic theory and would probably say that his ideas are relevant and not over simplified. Form in the world is the effect of other causes in a long, scientific chain of efficient causes by the interactions of atoms. In a way Newton's cosmological ideas are better because he was able to support interactions within the universe ...
- 2418: The Effects of UFO's on People
- ... colored balls of light, and disk shaped objects. Today unexplained aerial phenomena are generally referred to as unidentified flying objects (UFO's) or flying saucers. The effects of extra terrestrial sightings can have an adverse effect on people if influenced the wrong way. No solid proof has shown that UFO's are real, but many sightings cannot be proven otherwise. The media, stories, or one's own experience may often influence ...
- 2419: Salt and Its Uses
- ... early death. By many doctors and researchers are now beginning to feel that salt has gone too far. At the University of Alabama, a short-term research has been done on 150 people on the effect of the intake of salt related to high blood pressure. Result shows that those with normal blood pressure experience no change at all when placed in a extremely low salt diet, or later when salt ...
- 2420: Environmental Crisis
- ... population carrying capacity, unemployment and underemployment in the countryside, surging urbanisation, and spreading air and water pollution to mass illiteracy and education in relation to development. SDI itself has added such new concerns as the effect of son preference on female infanticide and the sex ratio, the impact of a fast fertility reduction on population aging, and the implications of exempting the country's 55 minority groups from the nation's ...
