The Danger of Air Pollution Gaining Access to the Brain

Leave a comment

The reason pollution has a metallic taste and scent and that it burns the eyes when exposed to it is because the particles of air pollution are tiny enough that they can travel through nerve cells, and gain direct entry to the brain, where the olfactory bulbar meets the frontal cortex, as there is no blood-brain barrier at this point. The body protects itself through the blood-brain barrier, which means that particles within the bloodstream, cannot get directly into the brain. This system has a slight flaw however as the nose acts as a direct conduit for incredibly tiny particles to bypass this security mechanism

The Physics of the Pac-Man Universe

The game of Pac-Man allows players to exit the world on one side, and re-enter upon a completely different side without delay. Pac-Man’s universe appears to be a flat, two dimensional, rectangular shape, but in reality it must be cylindrical like a pipe, only with the 2 ends of the pipe touching, making Pac-Man’s universe actually in the shape of a donut

The Legality of Murder Against Transgender Individuals in the U.S. Using the Gay Trans Panic Defense

Leave a comment

In 47 U.S. states, the Gay Trans Panic Defense is a law which states that it is possible for a defendant to be sentenced to a lighter prison term after having killed a gay or transgender person simply by claiming the victim flirted with or hit on them, therefore triggering a legally justifiable beating and/or murder

English Prince Charles’ Environmentally Friendly Vehicles

Leave a comment

Prince Charles owns an Aston Martin Volante which has been retrofitted to run upon surplus British white wine and whey. Charles received the vehicle when he was 21 and requested that engineers find a more sustainable fuel source for its engine because of his initiative to address climate change and the issues facing humanity before the 21st century. The engineers who worked upon the project felt that the task was insurmountable during the beginning of their research however after having successfully built such an engine, it is now accepted that the retrofitted engine actually runs better with more power upon white wine and whey than it does upon petrol, and as an added bonus feature, Charles has proclaimed that he thoroughly enjoys the delicious scent of the vehicle as it runs. Charles also had his royal train retrofitted to run upon cooking oil, another task which was successfully completed so that Charles can use the train half a dozen times per year

The Advent of the Imaginary Number Concept

Leave a comment

The value of “i” which represents an imaginary number is quite useful for balancing seemingly impossible tasks like when resolving problems with electricity or wireless technologies. Working with wave functions involves working with the value of an imaginary number because of its ability to resolve mathematical problems. If numbers are thought of as a straight horizontal line on an X axis, with 0 in the middle, with all negative numbers on the left hand side of zero (e.g. -1, -2, -3 etc.) and all positive numbers on the right hand side of zero (e.g. 1, 2, 3, etc.), then imaginary numbers would be plotted upon the Y coordinate axis, displayed vertically (e.g. +1i, +2i, +3i going up or -1i, -2i, -3i going down etc.). This allows imaginary numbers to be treated the same as regular numbers, just upon a different plane of axis. Imaginary numbers are essential to certain tasks like aircraft radio tower control as imaginary numbers allow for technologies like Radio Detection And Ranging (RADAR)

How Phosphorescence Works

Leave a comment

Glow in the dark products work because of a chemical additive which allows the product to absorb energy on one frequency, and reemit it as visible light which is a different frequency. Zinc sulphide and strontium aluminate are the most commonly used phosphors for photoluminescent products as they reemit energy over a considerably long period. When light is shone upon a glow in the dark object, incoming photons excite the phosphor molecules and these molecules then release that energy taken in by releasing photons and creating a dim light glow. Different phosphors release energy at different rates and thus, the slower a phosphor releases energy, the longer it will glow. The human eye is most sensitive to green light in the dark which is why night vision technology was traditionally created with a green tint

The Cultural Practice of Polyandry in Tibet

Leave a comment

Polyandry occurs in various cultures around the world, the practice involving a single wife with multiple husbands. Polyandrous relationships often involve men who know eachother (e.g. siblings, extended family, or friends). The harsh mountain existence of Tibet has driven parts of Tibet to engage in this practice, with multiple adults needed within a household to ensure survival

The Role of Dabbawalas Within Indian Society

Leave a comment

Indian railways are unique in that they have what are referred to as “dabbawalas” which means “lunch box men” in Hindi as the term “dabba” means “box” or in this case “lunch box” in Hindi and the term “wala” means “man” in Hindi. These dabbawalas deliver food which has been cooked by the loved ones of the people who are eating it (e.g. spouse who cooks food while their significant other commutes to work. The first spouse has that food delivered to second spouse so that it is hot and ready to eat after having started the work day). This system works extraordinarily well as holding a bag while traveling upon any Indian train is nearly impossible due to the volume of people who use the railway each day. There are 5000 dabbawalas in Mumbai, India and this collective makes an astounding 200,000 deliveries per day, equating to each member of the group making an average of 40 deliveries each. Each dabbawala carries approximately 145 lbs. of food daily. The system is actually quiet elegant as some members pick up food, some members commute on trains with food, some members travel by bike or other vehicle with food, and all members typically share responsibility in that they trade meals if they run across a partner who is traveling the direction in which they need to go. This helps boost efficiency and allows for more income to be generated than if these individuals decided to work solo. Food is often marked with specialized code words so that dabbawalas know where something came from and where it is intended to be. Food is typically prepared by a clients wife, mother, or sister, but as India is changing and more women enter the workforce, shifts in who fills which role are beginning to emerge. Those who do not have a significant other at home who is available to cook for them will often have food prepared by restaurants or hotels and delivered via dabbawala. It typically costs 550 Indian Rupees ($7.75) per month which is affordable and within reach for most Indian citizens as even lower income members of society like dabbawalas earn 13,700 Indian Rupees ($192.00) per month. This system continues to flourish even as India moves into the 21st century with modern fast food and traditional restaurant establishments available to most people, as the cost is generally lower than eating out and the quality of the food is virtually always healthier. This is one of many reasons as to why leaders within this sector of business believe that the continued vitality of the industry will continue to last into the foreseeable future
