Cosmic rays are to scientists much like photons are to astronomers. Just as astronomers use light (or photons) to view our galaxy and beyond, scientists use cosmic rays to infer useful properties about our galaxy. In fact, cosmic rays offer one of the few ways in which scientists can actually sample real matter outside of our solar system. By identifying the various nuclei that are dispersed throughout our Galaxy, scientists hope to unravel the mechanisms that actually produce these nuclei -- from stellar nucleosynthesis to nucleosynthesis within supernovae to nuclear fragmentation. Just think, the iron in your blood came from a supernova billions of years ago in our solar neighborhood! To measure cosmic rays directly, before they have been slowed down and broken up by the atmosphere, research is carried out by instruments carried on spacecraft and high altitude balloons, using particle detectors similar to those used in nuclear and high energy physics experiments. However, there are other means of studying cosmic rays that reveal new information.. An analysis of cosmic rays using a cloud chamber reveals a connection between frequency and altitude.
Cosmic rays are high energy charged particles, originating in outer space, that travel at nearly the speed of light and strike the Earth from all directions. The term "cosmic rays" usually refers to galactic cosmic rays, which originate in sources outside the solar system, distributed throughout our Milky Way galaxy. However, this term has also come to include other classes of energetic particles in space, including nuclei and electrons accelerated in association with energetic events on the Sun (called solar energetic particles), and particles accelerated in interplanetary space.

...ojector illuminates the tracks from the side to make them visible briefly.
Fortunately, humans and animals on the surface of the Earth are largely protected by the Earth's atmosphere and by the Earth's magnetic field, which deflects low-energy cosmic rays away except over the polar regions. Some cosmic radiation does reach the surface of the Earth, and it is possible that people living at very high altitudes have a slightly higher risk of cancer because of this. Cosmic rays can seriously damage DNA. If DNA damage cannot be repaired by the cell, the cell could die. If the damage is copied into more cells, then a mutation could occur. Exposure to large amounts of cosmic rays could increase the risks not only for cancer, but cataracts and neurological disorders. Long term exposure to cosmic rays, or short intense bursts, could affect the evolution of life on Earth.

The Use of X-rays for Diagnosis and Therapy Essays

- According to Oxford Dictionaries, an X-ray, also known as a type of radiation is defined as an electromagnetic wave of high energy and very short wavelength (between ultraviolet light and gamma rays), which is able to pass through many materials opaque to light and being absorbed to different degrees by different materials. In medicine, an X-ray is produced by the deceleration of charged particles, especially electrons, or by electron transitions in atoms. An X-ray machine sends these particles through the body....   [tags: Use of X-rays]

The History of the X-Rays Essays

- ... (2.) A man named William David Coolidge solved this debacle by creating the vacuum sealed Coolidge Tube, which not only allowed an increase in power through the tube that allowed better pictures, but it also permitted more stability in the x-ray tubes, thus giving them a longer working lifespan. The Coolidge tube could operate to energies up to 100,000 volts. General Electric went on to make x-ray tubes capable of operating at energies up to 1,000,000 volts, which gave the x-ray technology enough stability to become industrialized and mass produced....   [tags: crystals, rays, medicial, industial]

Morality in Measure for Measure by Shakespeare Essay

- Morality in Measure for Measure          Shakespeare's play, Measure for Measure, focuses on human morality. The play also explores the question of what kind of sexual conduct is socially acceptable, and what is not. The play depicts various attitudes toward prostitution, promiscuity, and premarital sex. But it also suggests that human laws and perhaps human morality are quite arbitrary and relative.   Measure for Measure considers the need for statutes and laws to govern sexual appetites and ensure domestic tranquility....   [tags: Measure for Measure]

Essay on Abstinence and Orgy in Measure for Measure

- Abstinence and Orgy in Measure for Measure        Many existing views of Measure for Measure seem intriguing but incomplete. They might reinforce our perception of this play as fragmented and baffling, because they do not integrate apparently conflicting outlooks presented in the play’s Vienna, and generated by the mysterious action of Vincentio. Notice how the following different interpretations display the conflicts: the extreme view proposed by Roy Battenhouse that the Duke stands for God (Rossiter 108-28); the modified position of Elizabeth Marie Pope that the Duke is a successful magistrate with divinely-delegated powers ("Renaissance" 66-82), almost in line with Eliade’s version of...   [tags: Measure for Measure]

Exploring Morality in Measure for Measure Essay

- Exploring Morality in Measure for Measure    In Measure for Measure, Shakespeare is able to examine the concept of right and wrong through the characters of Mistress Overdone and Mariana. Throughout the play, by using characters that most people would find morally reprehensible, Shakespeare is able to give the audience a different view of these people and, hopefully, show his audience that people aren't always what they appear to be. Through the character of Mistress Overdone, Shakespeare is able to bring a jovial side to the oldest job known to man -- prostitution....   [tags: Measure for Measure]

Measure for Measure Essay: Angelo

- Angelo in Measure for Measure       Within Measure for Measure, the character of Angelo can be seen as a case study of will over moral nature. Angelo, a deputy, is given the Dukes authority to act in his behalf while the Duke is away. The story unfolds as Angelo uses the agency he's been given in ways that many men in authoritative positions have done. It is interesting to follow his line of thought and to realize that this is a man who is not unlike many others. The main conflict between Isabella and Angelo is a contemporary problem....   [tags: Measure for Measure]

The Good and Evil Angelo of Measure for Measure Essay

- The Good and Evil Angelo of Measure for Measure                  In Shakespeare's Measure for Measure, Angelo emerges as a double-sided character.  Scholars have argued for centuries whether or not Angelo is a moral character or an evil character.  Those scholars who support the notion of Angelo as moral often cite the following facts: the Duke obviously trusts Angelo, Angelo is disheartened enough by the end of the play to offer a sincere apology, and Angelo tries to resist the temptation that Isabella presents.  On the other hand, others have argued that Shakespeare depicts Angelo as a purely evil man.  These critics emphasize Angelo's treatment of Marian, the Duke's possible suspicion...   [tags: Measure for Measure]

Measure for Measure Essay: The Virtuous Isabella

- The Virtuous Isabella in Measure for Measure        Measure for Measure is not a celebration of family values, the play points towards both the political virtuosity, which sustains the comic, and the humbler self-knowledge that preserves the integrity of the virtuoso. Human virtue can only be chosen in freedom, but we need not deny ourselves the opportunity of ensuring that this choice is not stifled by the subtly related powers of abstract intellectualism and carnal necessity   Isabella in Measure for Measure personifies innocent virtue....   [tags: Measure for Measure]

Measure for Measure Essay: Immorality and Corruption

- Immorality and Corruption in Measure for Measure         In ‘Measure for Measure’, Shakespeare demonstrates that there is an innate immorality and corruption in the heart of man. Shakespeare illustrates that power does not cause corruption.  This is achieved by presenting the Duke, who has the most power in Vienna, as a moral hero, and conversely revealing the corruption of the powerless class through characters including Pompey, Mistress Overdone, and Barnadine.  Through all this, Shakespeare uses Lord Angelo in Measure for Measure to show that immorality and corruption is innate in mankind....   [tags: Measure for Measure]

Measure for Measure Essay: The Bed Trick

- The Bed Trick in Measure for Measure        Critics have referred to the concept of Mariana taking Isabella's place in Angelo's bed "the bed trick."  This plan of the Duke's, which is supposed to save Isabella, Claudio, and Mariana, appears to be almost corrupt and shameful, and is one of the reasons scholars consider Measure for Measure a problem play.  What exactly is going on here with all of these characters?  It seems almost uncharacteristic of the sweet, naïve, virginal Isabella to condone another performing such an act in her place.  Isabella is, in a sense, asking Mariana to perform the very act which she has not only been avoiding, but that she is disgusted by.  The fact that Isa...   [tags: Measure for Measure]
