Alpha Particles Nuclear Physics
758 wordsErnest Rutherford was born in New Zealand in 1871 as one of 12 children. It was Rutherford who first "split" an atom and who discovered the atomic "nucleus", a name that he invented. For this he is regarded as the greatest experimental physicist of his time. Rutherford was one of the first and most important researchers in nuclear physics. Soon after the discovery of radioactivity in 1986 by the French physicist Antoine Henri Becquerel, Rutherford discovered the three different types of radiatio...

Atomic Mass Mass Spectrometer
455 wordsThe moles beginning is traced back to the most basic units of matter, atoms. Since atoms are extremely small, scientists have perplexed a great deal over finding a way to measure atomic mass. They struggled to find a universal container that had the capability to mass atoms. Measuring the mass of one atom on a balance in grams is not practical, because the result in grams is an amount too small to be of any use in the laboratory. Fortunately, a new idea came about. If two or more same amounts of...

Liquid Fueled Rockets Liquid Fueled Rocket Fuel
901 wordsA rocket is a device that does not need atmospheric oxygen to burn its fuel, since it carries its own, either separately or in chemical combination with fuel. Rockets are propelled forward by gas or liquid being expelled backwards. Rockets work on a fundamental law of motion by Sir Isaac Newton that states, for every action there is an equal and opposite reaction. This helps explain how rockets fly on earth and in space. For example, the rocket fuel is exploded in a controlled way so that the ex...

Red Blood Cells Vitamin B 12
464 wordsAnemia is a disease of the blood. Anemia is characterized by a deficiency in red blood cells or in the concentration of hemoglobin in the body. These deficiencies are caused by either decreased production or increased destruction of blood cells. Anemia is most common among women in their reproductive years, infants, and the elderly. Because one of the major functions of red blood cells is to transport oxygen, a decrease in red blood cells decreases the amount of oxygen delivered to the body's ti...

Alpha 1 Antitrypsin Shortness Of Breath
907 wordsEmphysema is a condition in which there is over-inflation of structures in the lungs known as alveoli or air sacs. This over-inflation results from a breakdown of the walls of the alveoli, which causes a decrease in respiratory function (the way the lungs work) and often, breathlessness. Early symptoms of emphysema include shortness of breath and cough. Emphysema and chronic bronchitis together comprise chronic obstructive pulmonary disease (COPD). Emphysema is a widespread disease of the lungs....
