.... attention, speed dependent activities, and abstract reasoning dysfunction. Also mild language impairments begin to surface. In the moderate stage, language deficits such as aphasia and apraxia become prominent. Dysfluency, paraphasias, and bizzare word combinations are common midstage speech defects. In the severe stage the patient is gradually reduced to a vegetative state. Speech becomes nonfluent, repetitive, and largely non-communicative. Auditory comprehension is exceedingly limited, with many patients displaying partial or complete mutism. Late in the course .....

.... and ideas. This essay titled "Natural Selection and the Human Brain: Darwin vs. Wallace" takes a look directly at two hard fought battles between evolutionists and creationists. Using sexual selection and the origins of human intellect as his proponents, Gould argues his opinion in the favor of evolutionary thought. In this essay titled "Natural Selection and The Human Brain: Darwin vs. Wallace," Gould tells about the contest between Darwin and another prominent scientist named Alfred Wallace over two important subjects. These topics, one being sexual selection and the ot .....

.... hits the northern surface at an angle instead of hitting it directly. By hitting the earth's surface at an angle there is not as much radiation warming the surface. As the earth rotates and the sun moves further north the temperature increases and the weather turns warmer. During the three months of spring the sun continues to move north and warming the earth more efficiently. At around June 21st the sun is directly facing the tropic of cancer. At this time the movement north comes to a halt and the earth's surface is at its warmest point, the summer solstice. It is also .....

.... "What is fusion?" One simple way of explaining it is taking two balls of clay and mashing them into one, creating a new, larger particle from the two. Now replace those balls of clay with sub-atomic particles, and when they meld, release an enormous amount of energy. This is fusion. There is currently three known variations of fusion: the proton-proton reaction (Figure 1.1), the carbon cycle (Figure 1.2), and the triple-alpha process (Figure 1.3). In the proton-proton reaction, a proton (the positively charged nucleus of a hydrogen atom) is forced so close to another prot .....

.... out the surface of the airscrew blades. Attempts to utilize the "straight blade" propeller were made by balloonists. These contraptions were quite strange and hardly fulfilled their purpose of actually propelling the balloon. The basic propeller had evolved from the simple concepts of da Vinci, and was slowly becoming an effective means of aerial propulsion. To reach the next plateau of flight an increased knowledge of the propeller would be needed, and the mysteries of the propeller and mechanical power would need to be solved. These substantial tasks remained for a .....

.... dyslexia is derived from the Greek “dys” meaning poor or inadequate and “lexis” meaning language. Dyslexia is a learning disability characterized by problems in expressive or receptive, oral or written language”(Wilkins URL). Simply put, dyslexia means trouble with reading, writing, and spelling. Dyslexia is not stupidity, laziness, lack of interest, or anything to be ashamed of. Dyslexia is not a disease; it has no cure and it will not go away. It knows no age, gender, or class boundaries. “There is a significant disproportion between the sexes, however. The proportions of mal .....

.... and replenishes it, if it were to die, the ratio would change greatly after many years. It is the difference between this ratio now and the time is died that allows a date for it to be established. Potassium-argon dating, another dating method, is possible due to volcanic ash and rocks found near many fossil sites. Rocks and ash created in this manner contain potassium-40, but no argon. As time passes, the potassium-40 decays into argon-40. In the laboratory, the sample is reheated, and since argon-40 is a gas, it is released. The ratio of argon-40 released to potassi .....

.... packed 5 to 10 MB of storage, the equivalent of 2,500 to 5,000 pages of double-spaced typed information, into a device the size of a small shoebox. At the time, a storage capacity of 10 MB was considered too large for a so-called "personal" computer. The first PCs used removable floppy disks as storage devices almost exclusively. The term "floppy" accurately fit the earliest 8-inch PC diskettes and the 5.25-inch diskettes that succeeded them. The inner disk that holds the data usually is made of Mylar and coated with a magnetic oxide, and the outer, plastic cover, bends easil .....
