Combining oxygen with hydrogen extracted from hydrazine is how Mark Watney, in the movie “The Martian,” made water on Mars. We are going to need Watneys on earth too. 97% of the Earth’s surface is covered by water, but 96% of that is saline. And it gets worse. 3.4 million people die every year due to waterborne diseases. Water purification is a grand challenge today and is at the same scale as global warming and depletion of nonrenewable natural resources. I want to address this challenge. As a kid, out of curiosity, I used to study the ingredients in household chemicals. A lot of dangerous substances had very useful applications. Chlorine, for example, is both a poison to humans and the thing that makes pools swimmable. This kind of paradox about common household chemicals and what they do to water is what led me to take rigorous science courses in high school, where I nurtured my passion for chemistry, as well as biology, and physics. I participated in chemistry league competitions and Olympiads as a way to build my knowledge piece by piece, like building lego. I studied atomic structure, covalent bonds and ionization energy asking myself: Why? How do molecules stick to each other? When would it be advantageous to unstick them? …show more content…
This further led me, in my junior summer, to a mentorship program with Professor Jaehong Kim at Yale, during which I learned about various materials used for sustainable water treatment, such as fullerenes, carbon nanotubes, and nano-sized membranes. By the end of the summer, I was able to design my own “super-nanomaterial.” but I would have to wait until college to synthesize
During the time of the Apollo Moon Landing, the world glued itself on the possibilities of the future. The future became reality, and everyone, particularly Americans, became enchanted by the possibilities brought to attention. However, the world became so wrapped up in the illusion of the future they failed to grasp the problems of reality. Herblock's cartoon "Transported" brings us back to reality, showing the problems we need to focus on. (specify the audience)
Becoming aware of this is the first step to changing this so called “default setting”
I am sitting here completely dumb founded as I think about chemistry. How does chemistry relate to me? How do I relate chemistry? It is such a subject that I am unsure of how it fits into my life other than a class I took in high school. As I dig deeper instead of just scratching the surface, I realize that I use and will be going to use chemistry more and more in my life.
Chemistry relates to everything we touch, see, smell, hear, and taste because atoms make up everything in the universe. Chemistry influences so much in our everyday lives that it is hard to think of an activity that does not involve a chemical process in some way. The science also plays a major role in the human body. Our bodies are made up of chemicals, in fact almost 96% of our body mass is made up of four different elements: hydrogen, oxygen, carbon, and nitrogen. Besides the physical way I am affected by elements, chemistry also majorly affects me in my line of work as a certified nursing assistant. As a certified nursing assistant I work in a nursing home and
Water may be a renewable resource, but the world’s supply of drinkable fresh water is being consumed more rapidly than ever before, and most importantly, more rapidly than it can be replenished. Only 2.5% of water on Earth is fresh
Main Point 1: Us humans have overpopulated the earth and will continue to grow if actions aren’t took. We had a population approximate to 7.4 billion people living on earth in 2016. It takes about 40 years to increase the population by 3 billion. Earth can only hold 10 billion people max. Therefore, we will overpopulate the earth around 2040. We need to conquer another planet however, not all planets have the basic elements to sustain life.
NASA will get to Mars one way or another but it certainly won't be with the help of the U.S Senate. The government has cut back on funding for the space agency and has begun to apply pressure to their agenda. It seems to be a classic case of catch-22. Unless some outside force like SpaceX or even aliens could help the doomed space agency, they may just remain grounded.
Water is the key to survival, it has very important role in living organisms. Life on earth will be impossible without it. Water is considered one of the most sensitive and important subjects in the Middle East, where increasing water deficiency and quality decline of the available water are forthcoming According to the World Health Organization (WHO) the first line of defense is protecting water supplies from contamination (Al-Khatlb et al., 2005).
Imagine being able to live on a planet forty light years away! NASA recently discovered seven planets orbiting a somewhat nearby star. It is likely that many of the newly discovered planets have a chance of being able to support life. This relates to United States history, because NASA discovered these possibly habitable planets, it gives us a goal to learn more about them, and it shows we might be able to live on these planets one day.
Chemistry is the basis for understanding many important mysteries surrounding intelligent life. Chemistry explains evolution – all compounds being carbon based and the evolution of simple substances like amino acids into proteins then DNA. My favourite practical was the synthesis of Aspirin experiment – this further fuelled my interest in neuropharmacology.
Water, otherwise known as H2O, is an odorless & tasteless liquid essential in life, that supplies nutrients and allows species to continue to exist on this very Earth. It helps with functionality of the human body by regulating temperature, brain energy, muscles, relieving headaches etc. In modern times, 71 % of the Earth 's surface is covered with water while oceans hold over 96.5 % of all Earth 's water. It can be found just about anywhere from rivers and lakes to icecaps and glaciers, in the ground, and even in humans and other animals. Nearly 57 to 60% of water is found in an adult body while in infants 75 to 78% of water is found. We depend heavily on water for survival everyday. As humans, we can survive only a month without food and only a week without water, which is why it’s crucial that we maintain proper filtrations and purifications of our water systems nationwide. Globally, The United States of America (since the early 1950’s) is the only country that uses Fluoride in their water in order to lower amounts of tooth decay unlike other countries ( although such health benefits haven’t been proven nor
Water is without a doubt the most precious resource on Earth; it is not only essential to the survival of our planet, but it is also essential to the survival of human beings and animals. As humans, we need access to clean water for several reasons, including physical, environmental, and industrial conditions. However, the most crucial aspect of clean water is our survival. Sixty percent of the human adult body consists of water, and it is vital in order for our bodies to function properly (The USGS Water Science School, 2016). A body can survive up to a month without food, but without water it can only survive about one week (All About Water, 2004).
Nasa has planned for 6 men to embark on a manned one-way mission to Mars by 2030. They want to colonize the supposedly interesting red planet, costing upwards of 30 billion dollars.
Access to clean water is a basic human right and yet people around the world don’t have that right and they struggle to survive without it. The many uses of clean and potable water include water for drinking to cooking other daily purpose. It is reported that over 1.1 billion people lack access to an improved water resource and three million individuals, and majority of them children, suffer and die from water-related disease. The need to improve water quality and providing clean water should be major project for developed countries like the US and so called “well developed countries”.
Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed.
