The polar bear is part of the Ursidae family and it’s scientific name is, Ursus Maritimus. It’s physical characteristics are that it is white, six to nine feet and 800 to 1,300 pounds. It feeds upon seals and fish for nutrients. The polar bear population is decreasing drastically because of global warming and is at an all time low of about 22,000. Even though they live most of their lives in the water, their home is on the ice nursing and taking care of their cubs. They were marked as threatened…

Sound is an amazing spectacle, it is a thing that is made up of vibrating waves that move up and down back and forth. Two ways to think of sound in a real life example are: 1st a slinky; the way it jiggles back and forth is much like how a sound wave can jiggle, 2ond a water wave; the way that the wave looks much like a squiggly horizontal line that is what sound waves act much like. A vibration, A.K.A the up and down slinky motion and the to and fro water wave motion, are called vibrations. A…

Experiment #6: Polarimetry Resolution of (∓)-Racemate: (∓)-ɑ-Phenylethylamine OBJECTIVE All chiral molecules have a mirror image of themselves. While they have the same physical properties, they interact with other chiral molecules completely different. Since there are many chiral molecules in organics, this can lead to the need to make optically pure products. If the chemist does not, it can lead to many problems including death. In this experiment, the separation of two enantiomers was…

Introduction The microscope is an optical instrument that produces large images of small objects that cannot be observed by the human naked eye. There are two types of light microscopes: compound microscope and Electron microscope. Light microscopes are divided into two categories: Compound microscopes and Stereoscope microscopes. Electron microscope functions in the following way; a stream of electrons emitted from an electron source built in the microscope, the obtained image is in black and…

The experiment is an investigation about the Zeeman Effect in an atomic Cadmium lamp. The part of the spectrum observed will be the 645nm (red) emission line. Electrons occupy energy levels within an atom when a photon of energy hf is absorbed by an electron in the n=1 level and if the energy is such that the electron is excited and ascends to the n=2 level after some time the electron will then descend back to the n=1 level and a photon of hf will then be emitted again. Each atom has its own…

SHAH How to do HDR photography (lions) HDR Photography HDR (High Dynamic Range) photography is a form of image processing that uses a series of images captured at different exposures to produce one, amazing photo. The dynamic range is a term used to infer to the ratio of darkness to the light. The idea is usually to compress the compress the light and have it appear on the final processed photo or computer in the same manner the eyes sees it. According to Photography.TutPlus, a good digital…

Visual acuity Main article: Visual acuity Visual acuity is the eye's ability to detect fine details and is the quantitative measure of the eye's ability to see an in-focus image at a certain distance. The standard definition of normal visual acuity (20/20 or 6/6 vision) is the ability to resolve a spatial pattern separated by a visual angle of one minute of arc. The terms 20/20 and 6/6 are derived from standardized sized objects that can be seen by a "person of normal vision" at the specified…

Since ancient Greece, humanity has become fascinated with science. The development of new technologies that will further the existence of mankind, has been the goal for many great scientists. Through centuries of experimenting, the mid-evil era of alchemy, and many years after, Chemistry became a topic of much importance. During the 1800’s, science had become one of the most rapidly growing fields as explanations for how things work, or the technological progression allowing us to discover more.…

Are dogs colorblind? the answer yes/ no, they see in color, just not the way humans do due to the lack of certain cones in their eyes. Moreover, how does color blindness work in humans? To see how color works we first have to analyze how we perceive color. The way we see “Color” is determined by the wavelength of a stream of light. This means that each color of light has its own wavelength. The combination of all lightwaves (primary colors) produces white. The absence of lightwaves makes an…

Diagram of Prototype A that consisted of an octagonal prism with a length of 11 in. or 27.94 cm. and height of 10.16 cm., while we created corrugated layers within the prism. We decided to change all the dimensions to centimeters instead of using inches as the units. Tinkercad model of Prototype B that consisted of a hexagonal prism with a length of 27.94 cm., height of 10.16 cm., and sides of the base of 4.445 cm. WIthin the hexagonal prism consisted of 6 equilateral triangles are connected…
