Electromagnetic Radiation Infrared Radiation
1,377 wordsYou might remember the heroic role that newly-invented radar played in the Second World War. People hailed it then as "Our Miracle Ally." But even in its earliest years, as it was helping win the war, radar proved to be more than an expert enemy locator. Radar technicians, doodling away in their idle moments, found that they could focus a radar beam on a marshmallow and toast it. They also popped popcorn with it. Such was the beginning of microwave cooking. The very same energy that warned the B...

Henri Becquerel Marie Curie
1,212 wordsHenri Becquerel, a French physicist, was born in Paris on December 15, 1852. His grandfather, Antoine-Cesar Becquerel, had fought at the battle of Waterloo in 1815 and later earned a considerable reputation as a physicist. He made important contributions to the study of electrochemistry, meteorology, and agriculture. Henri father, Alexander-Edmond Becquerel, also made a name for himself in science. His research-included studies on photography, heat, and the conductivity of hot gases, and lumines...

Marie And Pierre Marie Curie
1,431 wordsAspirations come from hopes and dreams only a dedicated person can conjure up. They can range from passing the third grade to making the local high school football team. Marie Curie's aspirations, however, were much greater. Life in late 19 th century Poland was rough. Being a female in those days wasn't a walk in the park either. Marie Curie is recognized in history by the name she took in her adopted country, France. Born in Poland in 1867, she was christened Many Sklodowska. In the year of he...

Dna Molecule Von Laue
1,115 wordsIn The Double Helix, a reader can find James D. Watson's first hand accounts of the competitive race in science that led to the discovery of the structure of the DNA molecule. The DNA research Watson and his colleagues took part in demanded knowledge in many areas of expertise, but the most important area was that of X-ray analysis. By creating photographic two dimensional pictures of the three dimensional DNA molecule, Watson and his team were able to analyze these pictures and determine that D...

Dry Ice Petri Dishes
1,905 wordsA particle cloud chamber is a device that makes visible to the human eye the presence of certain particles and cosmic rays. This paper will discuss the process in which a successful chamber prototype was developed. This paper will also discuss how the chamber utilizes the properties of a supersaturated environment to detect these particles. Finally, plans for the future development of a larger model to study the charge and energy of particles through the use of a magnetic field is presented. The...

Ozone Layer Ultraviolet Rays
1,294 wordsAtmospheric ozone layer depletion is a serious problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone layer is a region of the stratosphere containing ozone, or O 3 gas. The ozone layer is essential to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However, industrial and domestic chemicals ...

The Eye And Laser Surgery
1,567 wordsA Functioning Eye (Emmetropia) The eye is the organ of sight. It is used in almost everything we do, from playing sport to reading. A normal and well functioning eye can focus objects and images, both near and far, perceive depth and adapt to changes in light. The perception of depth is due to having two separate eyes creating two separate images, while the ability to adapt to light change is attributed to the iris and the dilator muscles. However these two aspects of the eye are not involved in...

All living organisms would suffer from too much mutation in the organism that all of its major organs would just stop working; and the organism would die. Until the 1970 s and 1980 s, most people, including scientists, took the ozone layer more or less for granted. They assumed it was one of the earths natural features and that it would always remain the same, This attitude chan...

Stop Global Warming Carbon Dioxide
1,721 wordsEFTHIMIOS MARIAKAKIS The greenhouse effect and global warming are issues that are talked about by geologists all the time. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absor...

Ultraviolet Rays Gamma Rays
343 wordsI went to Hawaii on vacation to get a tan, but I got something else instead. Ultraviolet rays are stronger, and hotter near the equator. When I got home I got x-rays. I was sent for treatment with gamma rays. Wow! What a vacation. It was so hot that I had to jump into a pool just to cool off. Ultraviolet rays have wavelengths between 10 nm and 430 nm. They also have a very high frequency of about 10, 000, 000, 000, 000, 000 Hz. - 1, 000, 000, 000, 000, 000, 000 Hz. Photon energy emissions are al...

It is very complex and has many parts and features which can have defects. However, to understand defects you must first know how the eye works. First light passes through the cornea, which is the transparent part of the sclera, or white of the eye, which is composed of tough fibrous tissue. Behind the sclera is a watery fluid called the aqueous hum...

2,387 wordsRadium is a silver-white, highly radioactive element. It? s atomic number is 88, and it is the heaviest alkali earth metal, having a mass number of 226. 025 (See Figure 1). Radium has at least twenty six isotopes, and all are radioactive (Shriver 1995). Since radium is chemically similar to calcium and magnesium, it is absorbed by the bones of animals. Once in the bones, it emits alpha, beta, and gamma rays (Shriver 1993). These rays shrink or destroy tissues and they are the reason radium is so...
