Astronomers Part One Brief Descriptions of the Following Astronomers: Walter Baade : Baade was a German-born American, whose work gave new estimates for the age and size of the universe. During the wartime, blackouts aided his observatons and allowed him to indentify and classify stars in a new and useful way, and led him to increase and improve Hubble's values for the size and age of the universe (to the great relief of geologists.) He also worked on supernovae and radiostars. Milton Humason :

Creationism Vs. Evolution
Creationism Vs. Evolution
Creationism vs. Evolution In my short life on this planet I have come to question things that many take upon blind faith. We all know that we must some day die; yet we continuously deny the forces at work inside ourselves, which want to search out the answers of what may or may not come after. It is far easier for humanity to accept that they will go to a safe haven and be rewarded for their lives with pleasures and fantasies of an unfathomable scale than to question the existence of a supposed

The Will To Power
the Will to Power In the Will to Power, Nietzsche claims: The will to power interprets (-it is a question of interpretation when an organ is constructed): it defines limits, determines degrees, variations of power. Mere variations of power could not feel themselves to be such: there must be present something that wants to grow and interprets the value of whatever else wants to grow. Equal in that- In fact, interpretation is itself a means of becoming master of something. (The organic process con

Fusion: Our Future's Energy? Fusion energy seems to be the most promising energy source of the not-too-distant future. It is safe, it uses an energy supply that is so abundant that it will never run out, it gives off harmless waste, and it produces energy comparable to the Earth's sun! But are there any problems with this hopeful energy source? What is Nuclear Fusion? To understand fusion, it is a good idea to know about fission. This is the splitting of the nuclei of atoms into two or more sma

Neutrinos and Gamma Rays Emission of a beta particle produces an energy change in the nucleus of an atom. The energy change that is observed, however, does not add up to satisfy the Law of Conservation of energy. The conservation law can be balanced if another particle, called the neutrino is part of this process. In the time it takes to read just this sentence, more than a billion of them will have passed unnoticed through the reader's body. Neutrinos may account for an appreciable portion of

Black Holes: Infinity And Beyond
Black Holes: Infinity and Beyond If theories of their existence are true, black holes are the most powerful force in the known physical universe. Many people are familiar with the term black hole, but few people actually know anything about them. A black hole forms as a result of a massive star running out of fuel to burn (Chaisson, 193). Once the star is no longer exerting outward force by burning off gases, it begins to collapse under it?s own intense, inward gravity (Chaisson, 193). It is lik

Why Is There Gravity? When you pick up a stone and release it falls to the ground. This seemingly simple concept has been known throughout history as gravitation. Isaac Newton managed to explain gravity in terms of its effects, but few have come up with a working explanation for the driving force behind it. The mysterious nature of some of the more peculiar effects of gravity, as well as the simple ones, indicate that explaining why there is gravity will be a long, difficult, yet intriguing task

Lasers

Lasers The light from lasers differs from ordinary light in several important aspects. Ordinary light from a light bulb travels randomly in all directions (unless the bulb is equipped with an integral reflector that directs the light). The light is thus incoherent. Even when incoherent light is directed with a reflector, it still spreads rapidly. The light from a laser is temporary and spatially coherent. This means that all of the wave-fronts of light are lined up in time and space (see Diagram

Units,Dimentions, Measures and calabration. CHEMTUTOR Measurement is the most useful form of description in science. Often the most useful measurements are those that have a number and a unit, such as ‘12.7 inches.' Here '12.7' is the number and 'inches' is the unit. This unit of inches in the example is one of the common units in the dimension of length. A number, then, is an expression in numerals. A unit is a recognized way to divide the essence of a dimension for measurement, and a dimension

Abstract Albert Einstein is one of the most known scientists that ever walked the Earth. He created theories that seemed to completely change the idea people have on the world and its characteristics. Einstein was able to form equations that explained how the earth worked and why it worked the way that it did. His early years were a little sketchy, but when he realized that his passion for physics and mathematics overpowered everything else, it all seemed to fall into place for him. Einstein was
