Answer: Radiation has a profound effect on matter. Particularly in forms where it has high energy. There are basically two kinds of radiation‚ and they are electromagnetic energy and particulate radiation. Low energy electromagnetic radiation isn’t generally hazardous‚ as long as the field strengths are low. You wouldn’t want to stand in front of a radar antenna when it’s radiating‚ but we are swept by low power electromagnet energy all the time. Those so-called radio waves are everywhere. Light

A Life Without Technology There’s no doubt that technology brings with it some scary things. The scariest of them all is of the uncertainty. Human beings are creatures of habit and any introduction of anything new typically raises an eyebrow (at least) or pitchforks (more often). It’s a somewhat common theme that is tiresome to me‚ but one that rages with debate throughout the times. If you study history‚ many of the same arguments that are made as to why the Internet is ruining our society and

scientists find themselves asking is "Is there life on other planets?" Since the first famously documented UFO sighting in 1947‚ the idea of extra-terrestrial life has been debated almost non-stop. The subject has inspired many TV programs‚ such as The X-Files‚ and films (Mars Attacks‚ Independence Day‚ and the Men in Black films to name but a few). Scientists have come up with many new ideas and ways of trying to either prove or disprove the existence of life elsewhere. Mars is a very similar planet

I could not be able to survive like Nya did. I would not be able to go what she went through. I think it would be physically impossible for me to survive like Nia did. I would not be able to whatsoever.I would not be able to have a good attitude. I would not have any mental toughness. I would also not have any motivation. If i was in her situation‚ I would not be able to have good attitude like Nya did if I was not with my family. I would go Crazy and complaint. It would be horrible I would be crabby

Life without Electricity In today’s society humankind has become dependent on electricity to be able to live and function. So how would the world be if we couldn’t rely on electricity? There would be no TVs‚ factories‚ cars‚ or even phones. Without electricity we would have to go back to our great great great grandparents’ ways of living. To entertain themselves children would have to learn how to use their imagination. In a world without electricity there would be no video games to play or TVs

The Impact of Aerosols on Solar Ultraviolet Radiation and Photochemical Smog R. R. Dickerson*‚ S. Kondragunta‚ G. Stenchikov‚ K. L. Civerolo‚ B. G. Doddridge‚ B. N. Holben ABSTRACT Photochemical smog‚ or ground-level ozone‚ has been the most recalcitrant of air pollution problems‚ but reductions in emissions of sulfur and hydrocarbons may yield unanticipated benefits in air quality. While sulfate and some organic aerosol particles scatter solar radiation back into space and can cool Earth ’s

Julius Scheiner was most likely the first person to realise there was a possibility of silicon being a basis of life. This idea was then grapsed by the british scientist James Reynolds in 1893. he then pointed out that its molecular integrity withheld in high temperatures which might allow life to exist at very high temperatures. Silicon seems promising when it comes to being the basis of life‚ but when the topic is researched futher. Carbon‚ when it is oxidized during the respiratory process‚ it becomes

in the field of human Services and I attend school full-time. As anyone can imagine I am always extremely busy. My days start at five in the morning and on average I don’t get to bed until midnight. I don’t even like to think of what life would be like without my computer because I use it through out most of my day. The school I attend requires their students to retrieve all the necessary information for his or her classes via internet. I also use the computer for several other reasons that are

can be a way to deliver messages‚ a poetic medium‚ a fine art‚ or nothing more than a source of entertainment. No matter what it is used for‚ music is the perfect art and our lives would be that much less complete without it that life as we know it would not at all be the same without music. Music is the perfect art. It has movement‚ because it progresses over a set period of time. All musical works have a beginning and an end. However‚ music does not restrict the audience in the way that movies
