Living Between Two Worlds Dayton Kwok Introduction As an American born Chinese, I’ve always had to switch between using English and Chinese. This is especially exacerbated since I lived in San Francisco, a city dominated by immigrants hailing from Southern China and Hong Kong. One moment I’m using English to talk to my friends, and the next moment I’m using Cantonese to talk to my family. My native language was English, but I also learned to speak Cantonese around the same time I learned to…

The theory of pro: An Italian perspective Introduction Universal Grammar (UG) is a linguistics theory which supports the idea that all human languages, although different in the surface, share some fundamental principles. These principles are generally true across languages, while parameters, on the other hand, are settings that allow for variation from language to language (White, 2003, p.2). The Extended Projection Principle (EPP) is a principle common to all languages which states that a…

protect an egg breaking on the ground, so can machines protect rovers when landed on a planet. Through viewing this, you can find out what type of machine my partner and I will use for our very own egg drop, and where you would see it contrasted in daily life. Withal, how gravity affects it and how drag, air resistance, and cushioning may help our device in landing. Additionally, you’ll find out our initial plan and how we believe it will help our egg survive the fall. The machine my partner…

fluidization velocity is used to determine the pressure drop. As mentioned above, when the solid behave like a fluid the bed is at fluidize state. So, minimum fluidization occur when the aluminum oxide start to far apart with each other and behave like a fluid. The experiment with different air flow rate between 2.0 to 20.0 L/min with 1 L/min…

This pressure that is dropped is measured using a pressure sensor that measures the difference in fluid pressure & when calibrated this pressure drop becomes a measure flow rate. The flow rate is given by, Qa = (Cd.A2/√(1-(A2/A1)^2))*(√(2(P1-P2)/P)) Where, Qa = Flow rate Cd = Discharge coefficient A1 = Cross-sectional area of the pipe A2 = Cross-sectional area of the orifice P1, P2 = Static pressures…

Ava Lilienthal Science Barcus 7-4 The Physics Behind Soccer Soccer really has a lot to do with science. From Newton’s laws of motion to the momentum of the person kicking the ball, the drag force and the magnus effect, and even the air pressure in the ball. It is harder than most people think. Next time you watch a soccer game, or play a soccer game, think about the science in the game. First, Newton’s Law’s are present when the ball is kicked. His first law, an object at rest stays at rest…

A scale model parachute will be designed and constructed to fall safely for the attached LEGO man to survive the parachute will provide enough air resistance to counteract gravity. One reason there is science in this problem is if the parachute goes to fast and kills the LEGO man to make the parachute go slower the parachute would have to be improved. Also, if parachute would be improved based on things such as how to make the air resistance greater making the parachute slower. Another, things…

vibrations, or more commonly known as vortex-induced vibrations (VIV’s), exerted on bluff bodies. Due to the production of vortex shedding beyond bluff cross sections, an alternating pressure distribution produces periodic fluctuations in lift and drag forces on the surface of the body; generating a vibrational response. This phenomenon plays a significant role in the design of common engineering structures such as bridges, oceanic structures, offshore drilling risers, cables, heat exchangers…

starts to lurch, I keep trying to swallow the stress but it feels like a hair dryer is blowing it back up. My knees start to buckle as I slowly inch forward in line. Drop after drop, yell after scream, I’m the first in line. “Next!” the lifeguard announces, clearly expressing that he has better things to do. My muscles tense. I have to drag myself to the clear…

inside lining of pipes or medical tubing it could greatly reduce drag and build up. This would reduce bacterial growth and clotting to a minimum. The textured surface enhances the flow of fluid and the texture of the wings give the impression that dirt and water would just roll off from its similar look to that of a cladded roof. Textures like these could even be utilized on aircrafts and water-crafts to act more aerodynamic and reduce drag. We constantly see self-cleaning surfaces like this in…
