Optometrist vs Ophthalmologist Understanding the difference between ophthalmologists and optometrists can be confusing for people seeking vision and eye care. There is some overlap in certain areas between an optometrist vs. Ophthalmologist, but there are also some very striking differences. Fortunately, once you have an understanding of what each of them do, you can know where to go to get the professional care that best fits your needs.

Acoustics is the branch of physics concerned with the study of sound. Sound is a wave made of vibrations in the air. Waves can be measured in a range of different ways: by their amplitude, wavelength, frequency, speed, and, at times, their phase. Sound information is transmitted by the amplitude and frequency of the vibrations, where the amplitude is experienced as loudness and frequency as pitch. The vibration is started by some mechanical movement and this causes a vibration on the molecules…

If one day, everybody disappeared from your life, and it was just you to survive, do you think you could? Well if not, how long do you think you could survive on your own? In the nail-biting novel Hatchet by Gary Paulsen, Brian finds himself on the ground in the Canadian Wilderness. After the plane crash, there was nobody around to help him. It was a miracle that he was saved after fifty-four gut-wrenching days. He struggled many times, but used the materials he had to somehow craft weapons and…

The bowl was not only carefully placed in Andrea’s home, but the real estate agent also places the bowl in the homes she sells. In the homes for sale, she positions the bowl in several locations that only when the looker’s eyes move “away from the refraction of sunlight on a pale wall, would they see the bowl” (596). This ray of light reflects against the pale wall and catches the eye of the…

The first lab error noted had to do with scratches on the test tubes used for the spectrophotometer. When inserting the tube into the Spec-20, slight scratches and damage on the tube might result in some light refraction; this would cause a slight aberration of absorption values. The liquids inside the test tubes would give off a reading greater than its actual absorption because of the scratches on the test tube. Used in the Beer’s Law plot, the slightly flawed…

Video 1 – costal erosion Boiol242 Week 3 Sandy beaches are a dynamic system that naturally experiences phases of erosion and accretion. Storm systems producing high energy waves that can rapidly erode sediments, particularly when infrequent or intense. During calmer periods, average swell waves deliver sediment back to the shoreline (beach accretion). Beach accretion is a much slower process than erosion whereby it’d take severl years for a beach to return to its pre – storm condition…

could easily reproduce to see the same results. He created experiments which demonstrated the reflection of light through the use of a darkroom with slits in an intermediate wall. Although he did not discover the rule for the relationship between refraction of light rays, his thinking was very similar to that of Snell. With this proof and the observation that the sky still illuminated after the sun had set, Al-Haytham was able to calculate the thickness of the atmosphere to 40 kilometers,…

Bergson has a very dynamic conception of self. His notion of the self is of one which is constantly evolving. While making a decision, for example, one’s selfhood is not just a witness of possible outcomes. Rather it is constantly morphing in the process of this deliberation. The inner dynamism of consciousness, according to Bergson, ensures that different states of our consciousness permeate and strengthen each other. And it is this dynamic series that would naturally lead to the formation a…

Analyzing the many works presented in the course, it was imperative to acknowledge the outside influences on the texts. Indeed examining the correlations between a text and its environment enables the reader to note relationships inherent not only in the text, but also across various works. Thus emerges the direct result of literature’s symbiotic relationship with its surroundings: shared characteristics across works in regards to culture, language, and form. One of the most apparent cultural…

Have you ever wondered why the night sky in the winter may look different to you than the night sky in the summer or fall? This is because we see the constellations at different times of the year for the different seasons- spring, summer, fall, and winter. Since the Earth orbits the Sun we do not get one constant area of constellations. The constellations we see in the summer are not the same ones we see in the winter. We never see the same constellation all year long. Unless the constellation…
