Synthesis of Salicylic Acid and Potentiometric Determination of Its Purity and Dissociation Constant

Union of Salicylic Acid and Potentiometric Determination of its Purity and Dissociation Constant â€â€â€â€â€â€â€â€â€â€â€â€â€â€â€â€- Abstract The reason for the examination is to combine salicylic corrosive from the ester, methyl salicylate, and decide the acid’s separation consistent and immaculateness. The ester was changed over to salicylic corrosive by base hydrolysis. The items were refluxed and recrystallized, to guarantee greatest immaculateness, and sifted, dried, and gauged. The dissolving purpose of the item was resolved utilizing a Fischer-Johns liquefying point device. The corrosive at that point broke up in independent containers with 95% ethanol and water and titrated with 0. 050 M NaOH, recently normalized with potassium hydrogen phthalate, through potentiometric titration. The pH after option of base was estimated and plotted against the volume of titrant included utilizing three unique plots. Results show a 61. 0% yield and the dissolving point contrasted from the hypothetical by a scope of 3. 11-6. 83%. The pKa determined was 2. 865, contrasting from the writing estimation of 2. 98, by 3. 86%. The hypothetical virtue of the example was 100. 0%, which contrasted with the trial one by 1. %; the trial immaculateness is 101. 7%. Potentiometric titration ends up being satisfactory in the assurance of the corrosive separation steady and virtue of an example. Beside that, the amalgamation demonstrated satisfactory given the high immaculateness of the item. â€â€â€â€â€â€â€â€â€â€â€â€â€â€â€â€- Keywords: co rrosive separation consistent virtue liquefying point ester INTRODUCTION Potentiometric strategies for examination depend on estimating the capability of electrochemical cells without drawing a lot, apparent current. For a considerable length of time, potentiometry has been utilized to find the endpoint in most titration set-ups. Skoog, et al. , 2004). Potentiometric strategies offer a bunch of points of interest, its principle advantage being its low operational expenses. Voltmeters and cathodes are, by and large, far less expensive than most current logical instruments. Models appropriate for direct potentiometry in field work, away from the research facility, are cheap, conservative, and simple to utilize. Basically nondestructive of the example, I. e. , addition of the anode doesn't radically change the organization of the test arrangement (with the exception of the slight spillage of electrolytes from the reference cathode), terminals are generally liberated from obstructions. Stable potential readings are accomplished decently quickly and voltages are handily recorded as elements of time. At last, the wide scope of analyte exercises, over which a portion of the accessible marker anodes display stable, almost Nernstian reactions, speaks to a significant bit of leeway (Day and Underwood, 1991). Potentiometric titrations include estimation of the capability of an appropriate pointer terminal as a component of titrant volume. This pointer terminal is speecific to the hydronium particle, H3O+. It offers adavantages over direct potentiometry in that it isn't reliant on estimating outright estimations of Ecell. This is expected to having the estimation dependent on the titrant volume that causes a quick change in potential close to the comparability point. This makes the procedure generally liberated from the juction potential vulnerabilities as this potential remains around consistent during the titration procedure. Rather, the titration results rely intensely upon having a titrant with precisely known focus. The instrument just signals the endpoint and carries on like a customary substance pointer. Beside that, the reference anode potential need not be known. Above all, ionic quality impacts are not significant in the titration technique in light of the fact that the outcome is analyte focus, regardless of whether the anode reacts to exercises. The separation of a feeble monoprotic corrosive is given by the condition HA †H+ + A†(1) [H+][Aâ€] [HA] where HA is the monoprotic corrosive, and A†is its conjugate base. The relating harmony steady for this corrosive separation is characterized as Ka = (2) Ka[HA] [Aâ€] which, when trying to discover [H+], reworks to [H+] = (3) Prior to the identicalness point, before any titrant was included and the analyte is the main species present in arrangement, the pH of the framework is determined from the convergence of that analyte and its separation consistent. For the situation where a frail monoprotic corrosive is being titrated with a solid base, resulting expansion of the titrant will make a response happen between the corrosive and the base. HA + OH†> H2O + A†(4) The nearness of the corrosive and its conjugate base in arrangement will cause the development of a cushion arrangement, which are arrangements that oppose an extraordinary change in pH, should a solid corrosive or base be added to the framework. At these focuses, the slant of a built titration bend is at its base. This is the pre-identicalness point. There is a point during the pre-comparability point locale wherein both the corrosive and its conjugate base are available in equivalent sums. This happens when half of the corrosive has been killed, or when the titration is at the half-identicalness point. Now, the buffering limit of the framework is at its most extreme. Beside that, disentangling Eq. 3 now by assessment, the [H+] is equivalent to that of the Ka. Taking the negative of the logarithm of the two sides, one will have the option to get the connection pH = pKa (Skoog, et al. , 2004). In this way, the separation consistent might be registered through deciding the pH at half-proportionality point. This examination will utilize salicylic corrosive as the analyte. Salicylic corrosive, Fig. 1. Salicylic corrosive is a feeble monoprotic corrosive, fit for discharging the acidic hydrogen associated with the â€COOH gathering. The hydrogen of the phenol bunch is difficult to discharge in light of the fact that the oxygen is balanced out by reverberation. Salicylic corrosive is a normally occuring substance, typically delivered by plants. It is found chiefly in the willow's leaves and bark. The unadulterated corrosive has a few helpful therapeutic properties. It is an antipyretic (fever reducer), pain relieving (torment reliever) and calming (growing reducer). Be that as it may, unadulterated salicylic corrosive makes for a very disagreeable medication. Salicylic corrosive contains two acidic practical gatherings, the phenolic (C6H5OH) and the carboxylic corrosive (RCOOH) gatherings. These gatherings cause the corrosive to be an aggravating substance that consumes the fragile coating of the mouth, throat, and stomach, henceforth its esterification to acetylsalicylic corrosive or anti-inflamatory medicine, before ingestion as pain relieving (Reed College, 2009). Esterificaton is the procedure by which a carboxylic corrosive is changed to an ester. Esters are natural exacerbates that are inferred for the most part by responding a carboxylic corrosive and a liquor. The general equation for esters is with the RC=O bunch gotten from the parent carboxylic corrosive, and the â€OR’ bunch from the parent liquor. The component for the response of the liquor and carboxylic corrosive to shape the ester is as per the following: Fig. 2. System of Esterification from a Carboxylic corrosive RCOOH and liquor R’OH Esters may likewise be orchestrated by responding the carboxylic corrosive with different reagents, for example, SOCl2 to frame the acyl chloride, which will at that point be treated with a liquor in pyridine, to esterify it. Esters are among the most across the board of all normally occuring mixes. Numerous esters are wonderful smelling fluids that are answerable for the fragrant scent of leafy foods. For instance, methyl butanoate is discovered n pineapple oil and isopentyl acetic acid derivation is a constituent of banana oil. The ester linkage is likewise present in creature fats and other naturally significant atoms. The substance business likewise utilizes esters for an assortment of purposes. Ethyl acetic acid derivation, for instance, is normally utilized as a dissolvable whi le numerous dialkyl phthalates are utilized as plasticizers to shield polymers from being fragile (McMurry, 2004). Methyl salicylate is delivered by numerous plants. It was first confined from wintergreen leaves, Gaulthea procumbens, and is regularly known as oil of wintergreen. Fig. 3. Methyl salicylate An ester of salicylic corrosive and methanol, it veils one of the acidic hydrogens in salicylic corrosive by supplanting it with a methyl (CH3â€) gathering. Subsequently, it is a generally lifeless intensify that doesn't discharge salicylic corrosive productively into the body. It is, consequently, not a successful pain relieving, or torment executioner. In any case, it is added to numerous items, quite for its scent, particularly root lager and liniments. With the goal for it to be actuated, methyl salicylate must be changed over to salicylic corrosive by natural combination, explicitly through saponification, a procedure much the same as that experienced by creature fats to become cleansers (McMurry, 2004). In this examination, salicylic corrosive will be orchestrated from methyl salicylate by base hydrolysis. Its separation consistent will likewise be estimated through potentiometric titration. In like manner, the level of virtue the salicylic corrosive utilized in the response will be in like manner decided. Approach In combining salicylic corrosive, 1. 2 g of sodium hydroxide (NaOH) were broken down in 7 mL water in a round base flagon.. Half of a milliliter (0. 5 mL) of methyl salicylate was added to this blend. The blend was then efluxed for 15 minutes and cooled to room temperature. One-milliliter augmentations of 3 M sulfuric corrosive (H2SO4) were included until the development of a white encourage, salicylic corrosive. Half of a milliliter (0. 5 mL) of the corrosive was added to guarantee total precipitation of the item. The blend was then cooled in an ice water shower with a temperature of at generally 5 °C for the response to die down. The item was then separated and flushe d with cold water, and recrystallized in water. The solids were then sifted on a pre-gauged channel paper and air-dried in the storage

Working Seeples Yasmina Dardari MIA ’17 COLUMBIA UNIVERSITY - SIPA Admissions Blog In addition to taking 14 to 16 credits a semester and participating in student groups, some SIPA students also work part-time jobs or internships. Earlier this semester, SIPA News spoke with Yasmina Dardari MIA ’17 to discuss how she manages the demands of school, her social life, and her internship at Unbendable Media. What did you do before coming to SIPA? I worked in D.C. for a few years at public-interest communications firm that did work for nonprofits and governments. I decided to attend SIPA to dig deeper into my own interests in media and human rights and also explore some of the the policy issues my clients were working on. I’m really into media, politics, public relations, strategic campaigning, and human rights. My specialization in Technology, Media, and Communications and my concentration in Human Rights and Humanitarian Policy allows me to combine all of these interests. What do you do at Unbendable Media? Unbendable Media is a team of communications practitioners that do campaign strategy and public relations work for organizations that aim to build a better, more progressive world. A former colleague started the company and and reached out to me to join his team. I do much of the same work I did with the firm in D.C.â€"providing campaign strategy and public relations works for organizations working for the public interest. Having this particular part-time job has really informed my SIPA education. My clients work on the same policy problems that we work on at SIPA, so my work informs school and school informs my work. It’s like a two-way symbiotic relationship that makes me a better employee and student. Why Unbendable Media? I wanted to keep myself sharp in the field that I care about, so I started interning at the organization last summer. They liked my work and asked me to stay on as a part-time worker. I enjoy the work, so it was a no-brainer to accept the offer. It will allow me to work in media and politics, which is where my heart is. How do you balance your school and work commitments? It’s not easy. It’s give and take. Ideally I wouldn’t have to work while attending school, but financially I can’t afford not to. I didn’t work my first semester, which allowed me to throw myself into my studies. I was able to go to lectures and fully dedicate myself to schoolwork. It became difficult after that because I was the co-president for the Middle East Dialogue Group and had an assistantship in addition to my part-time work at Unbendable Media. Sometimes I feel like I’m missing out on the full SIPA experience. My schedule is exhausting but it’s taught me the value of self-care. I know now how important it is to keep my stamina up, so I’m smarter about taking breaks and making efforts to spend time on my hobbies and see friends. Also, my time management skills have improved so much because of this experience. I make sure I’m on track and hit my benchmarks. My life would be a lot less stressful [if I didn’t work outside SIPA], but you can make it work if you have structure. This interview, conducted by Serina Bellamy MIA ’17, has been condensed and edited.

Everyday life and the Internet is entwined, the Internet has transformed modern behavior, and virtually every aspect of living, is both widely known and a source of ongoing study. In plain terms, such unlimited access to information and communication has radically altered concepts of self and community.

Marshall McLuhan quoted: â€Å"When something becomes commonplace people don’t identify it as everyday life, it becomes almost invisible†. This unconscious control associated to other elements of everyday routines, such as showering, cleaning, from a long inner structure we recognize, these activities are built into our psyches from a very young age, fabrics of living from generations of ones family or society in which we live, a formula for everyday routines. These activities vary from culture to culture; both reflect each community or environment in which they live. Faith and Spi rituality was main focus for my subject choice, raised in a large extended strict catholic family, although my immediate family today do not participate in partaking rituals, but religion hold a strong fabric.

Physics and Science Free Essays

string(69) " on a far from trivial in the everyday sense of the physical theory\." Of course, nuclear explosions, power sources, â€Å"lawlessness† of computers and lasers, new materials show that the focus of interest of scientists extends far beyond the â€Å"fragments of the last century. † However overact image of the scientist, and the whole science – tenacious. Although little can be so far from the truth as painting created impressionable and ardent poet. We will write a custom essay sample on Physics and Science or any similar topic only for you Order Now Even when Mayakovsky wrote his verse, and in science and around Shakespeare’s dramas quite scale. To be understood correctly, I should note that the question â€Å"To be or not to be† as applied to humanity and not the individual, though considerable, was first raised by physicists precisely and on the achievements of physics. It’s not by chance that for about three centuries were marked by the science. People involved in it, opened and opened the fundamental laws of nature that determine the structure and movement of material objects in a large range of distances, time and mass. Ranges of these great – from the small, atomic and subatomic to the cosmic and universal. Of course, this is not physics said â€Å"Let there be light,† but they found its nature and properties, set contrast to the darkness, and have learned to manage them. In its work, physics, crucially the largest of them, have developed a certain way of thinking, the main elements of which is the willingness to rely on well-tested, fundamental laws and the ability of a complex nature, and the public, a phenomenon highlight the main element, as simple as possible, that allows us to understand the very complex phenomenon under consideration. These features allow physicists approach very successfully deal with problems often lie far beyond their specialization. Confidence in the unity of the laws of nature, based on extensive experimental material, confidence in their fairness, coupled with a clear understanding of the limitations of the applicability of existing laws physics pushes forward, abroad unknown today. Physics – the science is complicated. It requires a lot of intellectual effort from the people who do it. It is incompatible with the amateurish. I remember how, at the end of the University and the Shipbuilding Institute in 1958, I was standing at the crossroads – where to go next. And my father, very far from science, asked me if I could go back to engineering after a dozen years of studying physics. My answer was an unqualified â€Å"yes. † â€Å"In physics, after ten years of engineering? â€Å", – He said. My â€Å"no† and identified a further choice, which is not sorry and I do not regret a second. The complexity of physics and the importance of its results that create a picture of the world and encourage the spread of its ideas far beyond most of this science in the public interest to her. I will give some of these ideas, in the order received. This is a scientific (not speculative! ) Atomism, the opening of the electromagnetic field, the mechanical theory of heat, the establishment of the relativity of space and time, the concept of an expanding universe, and quantum leaps in principle, not because of the error, the probabilistic nature of the physical processes in the first place, the micro- level, the grand unification of all interactions, establishing the existence of not directly observable subatomic particles – quarks. Here then there are popular books that are designed not to teach physics beginners, and explain her interest. There is another purpose of popular books, including the very well-known to people of my generation is â€Å"Entertaining Physics† Yakov Perelman, not relative ME Perelman. I am referring to a demonstration of how much things in everyday life, familiar to us technique and technology, one can understand qualitatively, based only on the well-known fundamental laws of physics in the first place – the law of conservation of energy and momentum, and the confidence that they are universally applicable. Objects of the laws of physics are vast. Why not pour water into the boiling oil, why stars twinkle in the sky, why is twisted water, emerging from the bathroom, why crack the whip and why the driver spins it over his head, to enhance the sound of the click, why ever would try to jump off the rail locomotives, but never make it electric? Why roars menacingly approaching plane and moving away, he moves to a falsetto, and why dancers or figure skaters begin to spin, throwing open wide â€Å"arms,† but then quickly pressed his hands to the body? Of the â€Å"why† of each in everyday encounters, not to mention not everyday life in abundance. They may be useful to learn to see, train yourself to find incomprehensible. Books by E. Perelman contain a record number of such questions â€Å"why? † (Five hundred), give them the answers, in most cases – definitely right, sometimes – beckoning to the discussion, occasionally – probably incorrect, provoking disagreement. There are questions that science has to date simple and generally accepted answer. Hence, the reader is room for an intense intellectual work. Along the way, the author explains the ell-known professionals to but less severe confusion among outsiders. That is, the author emphasizes the operational nature of many of the definitions in such a universally recognized exact science like physics. Professionals know that even the most fundamental of concepts, which operates physics, such as time and energy, space and momentum adjusted as fur ther development of science itself. Even the vacuum, once the analogue of absolute emptiness, lack of anything was self-evident in the â€Å"empty† space in time â€Å"overgrown† means non-trivial features of the primitive raises complex object of study. Versatility physical approach dictates a similar attitude to the definitions of non-trivial concepts and other areas that are very far from physics. Read books mentioned ME Perelman interesting and professionals – to argue, to find other, allowing a simple, sometimes graphic, explaining the issue. But a layman can expand your horizons, not necessarily rushing to their own, different from the author, explanation. It is worth remembering that the writing – verbal impression, often greatly simplified, with sometimes very complex physical concepts, based on a far from trivial in the everyday sense of the physical theory. You read "Physics and Science" in category "Papers" No need to follow the example of the real character, the director of one of the Moscow Research Institute who denied particular theory of relativity (general he chityval! ) Because the formula is the speed of light! â€Å"What would happen if the light off? † – Wrote in the science department of the Central Committee of the CPSU venerable gunmaker. Studying physics, beginning to understand its laws, shall be attached to the special beauty, there is actually an extra dimension to the perception of the surrounding world. This was written when – the great physicist Richard Feynman, noting that understanding the nature of the glow of stars, the mechanism of their birth and death makes the picture night sky even more beautiful and romantic. I wish, in conclusion, to mention one, a few unexpected side benefit of knowledge of physics, though by no means superficial. About him once told Academician Migdal. It lights up in the mountains and attractions nearby couple. The young man explained his pleasant companion, why daytime sky is blue. He told her about the scattering of light, referred to Lord – theoretical Rayleigh. The girl was sitting with his mouth open, looking admiringly at the scholar. But of the bore, and he, showing carelessness and inattention to a senior, said that the probability of scattering of radiation is proportional to the cube of the frequency. Migdal but was already on the alert. Remembering a classic, it is appropriate only in a very weakened form, say, perhaps, academic â€Å"in thought, under the night darkness, mouth kiss the bride. â€Å"Young man, the probability of scattering can not be proportional to the cube of the frequency – it would clearly be contrary to the invariance of the theory with respect to time reversal. The relay, as it should be, the probability is not proportional to the cube, and the fourth power of the frequency! † – In his usual tone, dogmatic said Migdal. Needless to say, that triangle changes shape, and the fat was cathetus hypotenuse, reaching the top. In short, read about physics and who is not too late – learn it. It will pay off. Physics in Medicine Medical physics – the science of the system, which consists of the physical devices and radiation, medical diagnostic equipment and technology. The purpose of medical physics – the study of these systems for prevention and diagnosis, and treatment of patients using the methods and tools of physics, mathematics and engineering. Nature of the disease and the mechanism of recovery in many cases have biophysical explanation. Medical physicists are directly involved in clinical processes, combining physical and medical knowledge, sharing with the doctor responsible for the patient. The development of medicine and physics have always been closely intertwined. Even in ancient times medicine used for medicinal purposes physical factors such as heat, cold, sound, light, and various mechanical actions (Hippocrates, Avicenna and others). First medical physicist, Leonardo da Vinci (five hundred years ago), who conducted the study of mechanics of movement of the human body. The most prolific medicine and physics were to interact with the end of the XVIII – XIX centuries. , When they were discovered electricity and electromagnetic waves, that is, with the advent of electricity. To name a few names of great scientists who have made important discoveries in different epochs. End of XIX – the middle of the twentieth century. connected with the discovery of X-rays, radioactivity, theories of atomic structure, electromagnetic radiation. These discoveries are associated with the names of C. Roentgen, Becquerel, M. Sklodowska-Curie, D. Thomson, Planck, Bohr, Einstein, Rutherford. Medical physics has truly establish itself as an independent science and profession only in the second half of the twentieth century. – With the advent of the atomic age. In medicine, have been widely used radiodiagnostic gamma apparatus, electronic and proton accelerators radiodiagnostic gamma camera, CT scanners, and others, hyperthermia and magnetic therapy, laser, ultrasound, and other medical and physical techniques and instruments. Medical physics has many sections and titles: medical radiation physics, clinical physics, physics oncology, therapeutic and diagnostic physics. The most important event in the field of medical examination may be the creation of CT scanners, which have broadened the study of almost all organs and systems of the human body. OCT have been installed in hospitals around the world, and a large number of physicists, engineers and doctors worked on improving techniques and methods of bringing it almost to the limits of the possible. The development of nuclear medicine is a combination of methods and physical methods radiofarmatsevtiki registration of ionizing radiation. Positron-emission tomography imaging was invented in 1951 and published in the paper of Rennes. Physics and literature In life, sometimes without realizing it, physics and literature are closely intertwined. Ever since ancient times, people in order to convey to posterity literary word, used the invention, based on knowledge of physics. On the life of the German inventor Johannes Gutenberg is little. However, the great inventor, to convey to us the literary masterpieces studied the laws of physics and mechanics. Organized them in printing, he published the first book in Europe, which has played an important role in human development. The first Russian printer – Ivan Fedorov, was known to contemporaries as a scientist and inventor. For example, he was able to cast cannon invented multilateral mortar. A first remarkable images of the literary and art of printing – â€Å"The Apostle† (1564) and â€Å"Chasovnikov† (1565) will remain forever in people’s memory. The name of Mikhail Lomonosov we call one of the first in the series of the most remarkable representatives of the national science and culture. The great physicist, he left a number of works that are important for the industrial development of Russia. A large part of his scientific work took optics. He manufactured optical instruments and original mirror telescopes. Exploring the sky with their instruments, inspired by the infinite universe, Lomonosov wrote beautiful poetry: Opened an abyss full of stars. The stars of not, the abyss – the bottom †¦ Without such a science as physics would not be a literary genre as science – fiction. One of the founders of the genre was the French writer Jules Verne (1828 – 1905 gg. ) Inspired by the great discoveries of the XIX century, the famous writer surrounded physics glamor. All of his book â€Å"From the Earth to the Moon† (1865), â€Å"The Children of Captain Grant† (1867-68 gg. ), â€Å"20,000 Leagues Under the Sea† (1869-70 gg. , â€Å"The Mysterious Island† (1875 . ) are imbued with the romance of this science. In turn, many inventors and designers inspired the incredible adventures of heroes of Jules Verne. For example, the Swiss scientist – physicist Auguste Piccard, like repeating the path of fantastic characters he invented climbed into the stratosphere stratosphere, making the first step towards uncovering the mysteries of cosmic rays. The next fad A. Piccard was the idea of the conquest of the sea depths. The inventor himself sinking to the sea floor and to build them bathyscaphe (1948). For about 160 years ago in â€Å"Notes of the Fatherland† published â€Å"Letters on the Study of Nature† (1844 – 1845). Herzen – one of the most important and original works in the history of philosophy as well as natural science, Russian thought. Revolutionary, philosopher, author of one of the masterpieces of classical Russian literature works â€Å"My Past and Thoughts† – Herzen, however, was keenly interested in the natural sciences, including physics, he has repeatedly stressed in his writings. Now you need to turn to the literary heritage of Tolstoy. First, because the great writer was a teacher – the practice, and second, that his works relate to the natural sciences. Best known for the comedy â€Å"The Fruits of Enlightenment. † The writer is extremely negative attitude â€Å"to all kinds of superstitions,† he believed that they â€Å"hamper and hinder the true teaching it to penetrate into the soul of the people. † Tolstoy understand the role of science in society: first, he was a supporter of the organization of society on sound science, and second, it makes a powerful emphasis on the moral – ethical standards, and because of this science in the treatment of Tolstoy are secondary science . That is why Tolstoy ridiculed in â€Å"Fruits of Enlightenment† Moscow gentry in the heads of which are mixed science and Antiscience. I must say that at the time of Tolstoy on the one hand that time, physics is in deep crisis due to the experimental verification of the main tenets of the theory of the electromagnetic field, which disproved the hypothesis of the existence of Maxwell’s world ether, that is, the physical environment, which transmits electromagnetic interactions Of course, nuclear explosions, power sources, â€Å"lawlessness† of computers and lasers, new materials show that the focus of interest of scientists extends far beyond the â€Å"fragments of the last century. † However overact image of the scientist, and the whole science – tenacious. Although little can be so far from the truth as painting created impressionable and ardent poet. Even when Mayakovsky wrote his verse, and in science and around Shakespeare’s dramas quite scale. To be understood correctly, I should note that the question â€Å"To be or not to be† as applied to humanity and not the individual, though considerable, was first raised by physicists precisely and on the achievements of physics. It’s not by chance that for about three centuries were marked by the science. People involved in it, opened and opened the fundamental laws of nature that determine the structure and movement of material objects in a large range of distances, time and mass. Ranges of these great – from the small, atomic and subatomic to the cosmic and universal. Of course, this is not physics said â€Å"Let there be light,† but they found its nature and properties, set contrast to the darkness, and have learned to manage them. In its work, physics, crucially the largest of them, have developed a certain way of thinking, the main elements of which is the willingness to rely on well-tested, fundamental laws and the ability of a complex nature, and the public, a phenomenon highlight the main element, as simple as possible, that allows us to understand the very complex phenomenon under consideration.

The Harvey Memory Project - The Writers For Hire

THE HARVEY MEMORY PROJECT It’s hard to believe that it has already been more than a year since Hurricane Harvey dropped more than 30 trillion gallons of water along the Texas Gulf Coast, causing immeasurable amounts of destruction and devastation. To those who experienced the disaster firsthand, memories of those days (and the months of recovery after) are burned forever in their minds. In an effort to preserve, protect, and archive those memories, Rice University, Houston Public Library, Harris County Public Library, and the University of Houston Libraries have teamed up to form the Harvey Memory Project. The project, which is funded by the Rice Houston Engagement and Recovery Effort and by the Rice Humanities Research Centers Public Humanities Initiative, aims to collect various stories, pictures, and audio-visual recordings from people who survived the epic hurricane. The contributions that are collected will be held in a memorial repository, which will be available for use by both the general public and by researchers and students studying the history of Hurricane Harvey. For more information, to make a contribution, or to browse stories and pictures that have already been submitted, just click here: Harvey Memory Project.
