P1_1 Laser Power
Get PDFThe possibility of using a laser to provide power to a distant spacecraft via solar panels is examined. The power and divergence combinations of a laser required to outperform the Sun is determined at the distance of Pluto, a possible combination identified is a divergence of 3.5 × 10−6 rad, and a power of 260 TW. The results show that it would be possible however not recommended due to substantial inefficiency
'All Will be Amply Labelled…' The Educational Policies and Practices of the Horniman Free Museum
Get PDFThis work examines the policies and educational programming produced by the Horniman Free Museum in London prior to its closure in 1898. Relying upon primary sources, such as the writings of tea merchant and Member of Parliament Frederick Horniman and the staff of the museum, this article refutes previous scholarship on this museum and argues that the museum possessed a clear mission, curatorial and exhibition practices, and educational practices that were derived from late nineteenth-century museum practices and theory. By examining how the Horniman Free Museum created and described its policies and programming, this article presents a basis for further work on understanding how late nineteenth-century museums interpreted museum theory for constructing and displaying knowledge about the world
A1_1 Gwen Stacy’s Death, Physics or Just Storytelling?
Get PDFIn this paper, we examine the physics behind one of the most iconic scenes from Spider-Man comics, the death of Gwen Stacy. For Gwen to survive her fall without suffering from the whiplash effect, her body needs to experience a declaration of no more than 6g. This is possible if the web string acts like a spring system that extends 16.7 meters beyond its original length and can handle the forces exerted on it
P2_9 Leap Year? Get out of Here! Part 1
Get PDFIn this paper we investigate the feasibility of altering the Earth’s orbit, in order to remove the leap year. Since the Earth orbits the Sun with a period of 365.25 days, the orbital period must be reduced by 0.25 days. Under the assumption that the Earth’s orbit is circular at all times, we find that 1.22E30 J of energy must be removed from the orbit, and if this energy is to be removed over the course of one orbit, the acceleration of the Earth must be 2.17E−7 m/s^2 . Removing this energy will reduce the radius of the Earth’s orbit by 0.046
P3_5 Properties of a Kyber Crystal
Get PDFThis paper analysis the required properties for a lightsaber’s ”Kyber Crystal”. We conclude that it must have a power output of around 63.6MW to be able to generate a lightsaber temperature of 7680oK. It must also be able to generate an intrinsic magnetic field of 10.8mT
P2_8 Journey to the Depths of the Earth
Get PDFThis paper aims to determine velocity and travel time of a Bathyscaphe vessel as it descends to the bottom of the Mariana’s Trench and rises to the surface again. Using the density of the vessel while submerging as ρ_sink = 1100 kg/m^3 , the terminal velocity of the vessel is v_sink = 1.47 m/s and it will take 2 hours and 5 minutes to reach the bottom. Similarly, using the density of the vessel as it rises as ρ_rise = 1020 kg/m^3 gives a terminal rise velocity of vrise = 0.235 m/s and takes 12 hours and 59 minutes to reach the surface. The total travel time is 15 hours and 5 minutes
A4_4 Jack-Jack Keeps Falling On My Head
Get PDFIn The Incredibles, the antagonist, Syndrome, kidnaps the super human baby, Jack-Jack, by flying up towards a plane by using rocket-propelled boots. Jack-Jack attempts to escape him by turning his entire body into metal, causing Syndrome to drop rapidly due to the sudden change in mass. In this paper, we chose the metal platinum, and focus on the forces Syndrome will experience after Jack-Jack changes into platinum. We find that they would hit the ground with a velocity of around 38.7ms−1 and an impact force of 268.4MN, which is 500x to that of a car crash
A6_3 Traveling to the Future
Get PDFIn the special theory of relativity, a moving clock runs slow. This means that if a person was to move at high speeds away from earth and then eventually return, they would have aged less than someone stationary on the earth. In this paper, we determine the maximum theoretical amount of time the average person could travel to the future using this method and the velocity of the person as a function of the persons proper time as they take the trip. We found that the furthest a person could travel to the future is 267 million years. However, even an increase by just 10% to either the time of the trip by the persons perspective or to the acceleration can turn this answer from hundreds of millions of years to billions of years
P2_11 Predictive Model of Baking Cakes
Get PDFThis paper outlines the creation of a computational predictive model designed to estimate the time to bake a cake based on the total summed mass of its ingredients. The model constructed showed expected behaviours, with the centre of the cake increasing in temperature asymptotically to the oven temperature and gave reasonable agreement with baking times when compared to various online recipes
A1_4 Chickens Go In, High-performance Aircraft Come Out
Get PDFThis paper investigates how much thrust the plane from the film Chicken Run (2000) would require to take off. By using Mr Tweedy to scale the plane and making assumptions for the wing structure, body drag, and internal structure, a final thrust value of 18,000 N is found
