Svante August Arrhenius Svante August Arrhenius was born at Uppalsa, Sweden, on February 19, 1859 His intelligence and creativity were apperent nt from an early age--he taught himself to read when he was three Although credi ted with many scientific innovations, he remains best known for his ionic theory of solutions, For which he was awarded the Nobel Prize in chemistry in 1903 Arrhenius henius died in Stockholm on October 2, 1927 Science is a human endeavor subject to human frailties and gover

The Universe
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

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

Photography is a technique of producing permanent
Photography is a technique of producing permanent images on sensitized surfaces by means of the photochemical action of light or other forms of radiant energy. In today\'s society, photography plays important roles as an information medium, as a tool in science and technology, and as an art form, and it is also a popular hobby. It is essential at every level of business and industry, being used in advertising, documentation, photojournalism, and many other ways. Scientific research, ranging from

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 :

Black Holes
Black Holes On December 3, 1995, astronomers using the Hubble Space Telescope identified a black hole in the galaxy NGC 4621, located 100 million light-years from Earth in the direction of the constellation Virgo. This is the second super-massive black hole that astronomers using the Hubble Space Telescope have found. Astronomers believe that the mass of this black hole is about 1.2 billion times the mass of our sun, but it is concentrated in a space that is not any bigger than our solar system

Challenger
Challenger
Challenger It was a cold, crisp, and damp morning on the Florida Space Coast as the space shuttle Challenger raced through the sky at speeds approaching mach 2 at an altitude of 104,000 feet when something went perilously wrong. All of America watched, including the family members of the seven doomed crew members, as Challenger exploded into an expansive ball of fire, smoke and steam. An Oh. . . no! came as the crew’s final utterance from the shuttle as the orbiter broke-up. As the reality of
