radiating electric field (or electromagnetic signal) produced when radio stations broadcast? Include a description of what is producing the signal as well as the reasoning behind how this could produce a signal. We know that electromagnetic radiation is produced by accelerating charges. In the radio transmitter‚ electrons oscillate up and down and are thus accelerating. An electron will exert a force on another electron when they are some distance away‚ like charges repel. When the electron in

Chapter 1 From X-Rays to Ion Beams: A Short History of Radiation Therapy James M. Slater Abstract Radiation therapy (RT) developed in several eras. Patients’ needs for more effective treatment guided the efforts. The development of ion beam therapy (IBT) can be seen as a corollary in this continuous endeavor to optimize disease control while minimizing normal-tissue damage. It could not have materialized‚ however‚ without the curiosity‚ ingenuity‚ and perseverance of researchers‚ engineers

Living a human life/human nature Aristotle was a man of philosophy‚ science‚ and mathematics. He used these three tools to explain what he thought the purpose of being a human being was‚ and just what being a human being entailed. To describe what a human being was‚ he came up with many theories‚ which involved friendship‚ happiness‚ and human nature. He also believed that not everyone was a perfect human‚ meaning‚ there were things an individual must do throughout his or her life to achieve

The Universe and Our Galaxies The Universe and Our Galaxies Examples of Elliptical (Messier 87 ) and Spiral Galaxies (NGC 3559) Examples of Elliptical (Messier 87 ) and Spiral Galaxies (NGC 3559) Edwin Hubble was one of the first people to actually realise what a galaxy is‚ the measurement of the “Hubble Tuning Fork” Classification scheme shows how round or rightly wound their “arms” are. E0 means that an elliptical galaxy is extremely round‚ whilst E7 is flat. However not all galaxies

Electromagnetic radiation Electromagnetic radiation (EM radiation or EMR) is one of the fundamental phenomena of electromagnetism‚ propagating and traveling through space via photon wave particles‚ carrying radiant energy. In a vacuum‚ it propagates at a characteristic speed‚ the speed of light‚ normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave‚ it has both electric and magnetic field components‚ which oscillate in a fixed relationship to one

The universe is a vast and interesting place where there are many mysteries to explore and many adventures that we‚ as the human race‚ must partake upon. Many astronomers and scientists of all kinds have spent their time finding new discoveries and creating many new theories about different aspects of the universe. Some of these discoveries and theories include planetary accretion‚ the differences between inner and outer planets‚ the formation of planetary rings‚ how the asteroid belt got there‚

EDUCATION FOR THE DIGINITY OF HUMAN LIFE Education‚ if looked at beyond its conventional boundaries‚ forms the very essence of all our actions. What we do is what we know and have learned‚ either through instructions or through observation and assimilation. When we are not making an effort to learn‚ our mind is always processing new information or trying to analyze the similarities as well as the tiny nuances within the context which makes the topic stand out or seem different. If that is the case

In this review we will learn a lot of things about the effects of radiation in plants and some information about the plants and radiation. So as I go on my research I found out that‚ in moving from the water to the land‚ several living creatures had to subdue the number of problems. It must include the fortification against reproduction‚ fluid and nutrient transport‚ desiccation and ultraviolet radiation. So plants started from algae‚ it has been found in a long time photosynthesizing bacteria could
