Figure 1: Flywheel “D10 Flywheel” by tudedude is licensed under CC BY-NC-SA 2.0 Abstract Energy storage is vital to our modern-day society as a method of reacting to the supply and demand of electrical energy[1]. Alongside the global push to transition from non-renewable to renewable energy sources, there also exists a need to improve energy […]

The Lifespan of Alzheimer Disease

Posted Leave a commentPosted in Biology

Abstract Alzheimer Disease (AD) is a progressive neurodegenerative disorder that affects about 5.8 million people today, and is expected to grow to 13.8 million in 2050.[1] AD is a disorder that begins on the biochemical level with neurofibrillary tangles and β-amyloid plaques.[2] As the biochemical pathology accumulates throughout different regions of the brain, from the […]

Double slit experiment using Arduino and Light sensors

Posted Leave a commentPosted in Physics

1. Aim and Motivation  a. Motivation What is light? Many scientists from the past have questioned this. What I learned about light through science classes and literature research is that light has two different characteristics. In summary, light exhibits wave-particle duality. Scientific observation of the nature of light is a complicated problem. Einstein’s photoelectric experiment […]
