A4 5 Jellyfish Jam
No full textIn this paper, we investigate how many jellyfish are required to power Karen's laser from the show SpongeBob SquarePants for an hour. We calculate the energy released from an average jellyfish sting as well as the energy required to power a 5 W laser for an hour. Assuming each jellyfish produces one sting, we require 258 jellyfish to power this laser
A5 7 Life Under Plastic, is it Fantastic?
No full textThis paper calculates the minimum thickness of the polyurethane dome that the character Sandy Cheeks from SpongeBob SquarePants lives in to withstand the pressure on the seafloor of Bikini Bottom, and the minimum thickness of the dome to withstand the pressure at the deepest point in the ocean, Challenger Deep. We find Sandy’s dome would need to be at least 0.031 m thick to withstand the pressure at Bikini Bottom, and at least 5.6 m thick to withstand the pressure at Challenger Deep
Can we predict how many professional footballers in the UK will develop Alzheimer’s?
Get PDFThis paper will be looking be looking at if it is possible to predict how many professional footballers In the UK will develop the neurodegenerative disease called Alzheimer’s (AD) which is a progressive disease where symptoms worsen over time affecting brain function. Footballers and other sports where trauma is frequent to the head is known to be linked to AD through chronic traumatic encephalophagy which affects cognitive impairment and behaviour
Wastewater, the Future of Power in Leicester's Homes
Get PDFSewage poses a pollution problem because it is in constant production. The solution lies in its conversion into a resource and on the assumption of daily production, sewage energy has the potential of becoming a supplement to Leicester’s energy portfolio. Sewage energy can be maximised sustainably in several ways, while also pushing the city it supplies closer to being carbon neutral. This paper explores the possibility of sewage being used to power the households in Leicester, considering its population.
Isabela Madrigal can save the ocean.
Get PDFIsabela, a member of the magical Madrigal family in Disney’s Encanto, can grow and control all types of flowers and plants. This power can help her increase the pH of the ocean. Ocean acidification has left many marine animals and plants in danger. She can increase high carbon neutralising plants such as seagrass and mangroves and can make them survive in areas where they usually would not grow in
Museum Activists as Agents of Social Change in War
No full textThe author highlights the importance of museum activism as institutions become agents of social change in war. The article provides an understanding of how local stakeholders in conflict scenarios such as the full-scale invasion of Ukraine in 2022 can become empowered and develop effective strategies to preserve their values and rebuild their careers. In addition, the author presents examples of international solidarity which have supported Ukrainian museums and their workers. The research findings support the potential of museum activism in sustaining cultural heritage in times of conflict
An Exploration of The Lived Experience of Informal Student Carers During Covid-19
No full textInformal Student Carers (ISC) are students who provide unpaid care to a friend or family member needing support. We explored the lived experiences of ISC and the challenges they faced throughout the Covid-19 pandemic. A scoping review, questionnaire-based survey and volunteer interviews were undertaken to identify the themes which predicate student carer’s experience during the Covid-19 pandemic. Our research showed that a combination of financial concerns, time constraints, and the lack of visibility of student caregivers all contributed to this student group's poor mental health during the Covid-19 pandemic. Educational institutions have an obligation to be informed and support the unique and varied needs of ISCs
P1 4 Beau and Arrow
Get PDFThis paper explores the possibility of firing an arrow to split a stationary arrow in half. Considering Newtonian projectile motion, the initial velocity of the arrow was determined to be 125 ms−1 . This is within the expected range of velocities for recurve bow and longbow archers. An optimum firing angle was found to be 44.6◦ . Forces acting within the system demonstrate that an arrow made of iron and poplar could split the stationary arrow under the right conditions
P1 7 A Superhuman Jump
Get PDFThis paper calculates the force required for Mario to jump in close proximity to a black hole, as shown in Super Mario Galaxy. This value, FJ , was found to be 6.67×1016 N. We applied this value to a similar jump on Earth and determined that the velocity when Mario leaves the ground is 4.54×107ms−1 or approximately 0.15 c. This value is significantly higher than Earth’s escape velocity indicating Mario would never return to Earth if he jumped on the spot
P5 3 Insane Tea Enthusiasts
Get PDFFollowing our previous study, we continue our analysis of the boiling time of water in an extreme pressure environment. We find the pressure required to extend the boiling time of water for three cups of tea to one hour.Our result is an astonishing 1.5×1010P a, which is comparable to pressures present in the lower mantle of Earth.The discussion of this finding leads us to an interesting conclusion, which is the fact that, under such circumstances, water transitions into its most dense state of ice called the ice-VII
