Leonhard Euler
Leonhard Euler, (born April 15, 1707, died Sept. 18, 1783), was the most prolific mathematician in history. His 866 books and articles represent about one third of the entire body of research on mathematics, theoretical physics, and engineering mechanics published between 1726 and 1800. In pure mathematics, he integrated Leibniz's differential calculus and Newton's method of fluxions into mathematical analysis; refined the notion of a function; made common many mathematical notations, including e, i, the pi symbol, and the sigma symbol; and laid the foundation for the theory of special functions, introducing the beta and gamma transcendal functions. He also worked on the origins of the calculus of variations, but withheld his work in deference to J. L. Lagrange. He was a pioneer in the field of topology and made number theory into a science, stating the prime number theorem and the law of biquadratic reciprocity. In physics he articulated Newtonian dynamics and laid the foundation of analytical mechanics, especially in his Theory of the Motions of Rigid Bodies (1765). Like his teacher
Johann Bernoulli, he elaborated continuum mechanics, but he also set forth the kinetic theory of gases with the molecular model. With Alexis Clairaut he studied lunar theory. He also did fundamental research on elasticity, acoustics, the wave theory of light, and the hydromechanics of ships.
Euler was born in Basel, Switzerland. His father, a pastor, wanted his son to follow in his footsteps and sent him to the University of Basel to prepare for the ministry, but geometry soon became his favorite subject. Through the intercession of Bernoulli, Euler obtained his father's consent to change his major to mathematics. After failing to obtain a physics position at Basel in
1726, he joined the St. Petersburg Academy of Science in 1727. When funds were withheld from the academy, he served as a medical lieutenant in the Russian navy from 1727 to 1730. In St. Petersburg he boarded at the home of Bernoulli's son
Daniel. He became professor of physics at the academy in 1730 and professor of mathematics in 1733, when he married and left Bernoulli's house. His reputation grew after the publication of many articles and his book Mechanica (1736-37), which extensively presented Newtonian dynamics in the form of mathematical analysis for the first time.
In 1741, Euler joined the Berlin Academy of Science, where he remained for 25 years. In 1744 he became director of the academy's mathematics section.
During his stay in Berlin, he wrote over 200 articles, three books on mathematical analysis, and a scientific popularization, Letters to a Princess of
Germany (3 vols., 1768-72).
Amy Widener is a real estate agent, mother of two, and a sepsis survivor. In 2013 Amy was in the best shape of her life. She had just finished a Disney half marathon and was reaping the benefits of her intense training, little did she know that that training was going to save her life. One night she woke up with extreme abdominal pain and was rushed to the emergency room where she learned that she had a kink in her intestines. They performed emergency surgery and released her after a little bit of recovery. Instead of Amy’s pain getting better with recovery after her surgery, it got worse. This resulted in subsequent trips to the E.R. only to be sent home with more and more antibiotics. Two months after her surgery she went into the emergency
Antimicrobial therapy is the cornerstone sepsis treatment, and the therapeutic goal should be centered around administration of effective IV antibiotics within 60 minutes of septic shock or severe sepsis (without shock) recognition. The initial antimicrobial therapy should be empiric and focused on having activity against all expected pathogens (bacterial, fungal, viral), based on each individual patient situation. Daily reassessment of antimicrobial therapy should be performed, with de escalation in mind; procalcitonin levels can be of use to direct discontinuation in patients with no evidence of infection following initial septic
Sepsis is a problem of bacterial, parasitic and fungal infection. Due to this the body develops a systemic immune response to get rid of the infection or tissue damage. This causes inflammation throughout the body mainly found in small blood vessels or it leads to septicaemia which is where microbes or infections are found in the blood this can also be called blood poisoning. Septic shock is a life-threatening condition were hypotension occurs as blood pressure drops to a dangerously low level after an infection. In septic shock the patient may experiences tachyeordia this is where there is a greater heart beat than normal (90 heart beats a minute) and tachypnae were the patient is breathing faster than the normal rate (12-20 breathes per minute).

Currently in the United States, we have 2.3 million people incarcerated in prison and jail, and an additional 7 million people either on probation or parole, thus, making us the most incarcerated nation on the planet. In comparison, we have a bigger prison population than those of China and Brazil combined. Clearly, this has become a tremendous problem and has affected many people, generally poorer people of color. The people as described, usually come from a childhood of abuse, gang violence, poverty, and early victimization by law enforcement in impoverished neighborhoods. I believe the issue isn’t the people within the community, but rather the system the governors that community. I believe our corrupt justice system

In the last couple of years, many Americans including political leaders have agreed that our criminal justice system is deeply flawed, unsustainable and inefficient and needs to be reformed. Our criminal justice system was “created to keep communities safe, to respect and restore victims and to return offenders who leave prison to be self-sufficient and law-abiding” (DeRoche, 2012). However, it is not only the offenders but the criminal justice system itself. There are five major problems within our criminal justice system. The first and biggest problem is our overpopulated prisons. Each year millions of people are incarcerated in local, state, and federal prisons.

The Common Law, Criminal Justice System is one of three types of legal systems. The Common Law is used in the U.S and is presented as a type of legal system that bases most of their convictions by the court 's decisions. From having the most cases determined by the courts can look to be favorable to the rich who are able
Unequal treatment of minorities characterizes every stage of the process. This the price that is paid in order to keep this false fallacy of justice while African and Hispanic Americans, and other minority groups, are victimized by disproportionate targeting and unfair treatment by police and other law enforcement officials; by racially skewed charging and plea bargaining decisions of prosecutors; by discriminatory sentencing practices; and by the failure of judges, elected officials and other criminal justice policy makers to redress the inequities that become more glaring every
Auguste Escoffier Auguste Escoffier was born on October 28, 1846, in the village of Villeneuve-Loubet, France. He was the son of Jean-Baptiste Escoffier and his wife Madeleine Civatte. His father was the village's blacksmith, farrier, locksmith, and maker of agricultural tools. Escoffier's childhood dream was to become a sculptor. Unfortunately, he was forced to give up that dream at the age of thirteen, just after he celebrated his first Holy Communion.
Garden is a captivating composition. There are many elements in this painting, that altogether, make it a complete, finished work of art. Although the painting is asymmetrical, the placement of the lines and shapes give the perception of a balanced work. The artist has utilized the space by placing the focal point in the center and creating implied and actual lines to draw your eye to it and across the painting. It is an abstract artwork, and is representational of a true
Johann Heinrich Lambert didn’t come from the wealthiest of families. His parents were tailors. Therefore, at the age of twelve, recognizing his family’s financial condition, Lambert ceased traditional education and dropped out of school. He worked alongside his father in order to help provide. Lambert didn’t let this deter him completely, however. He was capable in both French and Latin, and spent his free time educating himself to the best of his ability. It wasn’t until after he became the assistant to Professor Basler Zeitung of Basel University, that he was able to return to his studies. He then had a brief stint as a clerk due to his impeccable handwriting. When he was twenty he tutored the sons of Count Salis ...
The United States prison industry is unlike any other in the world. It is very expensive and is largely ineffective in reducing the crime rate and the rehabilitation of its offenders. The Prison Policy Initiative, a nonprofit organization devoted to finding the hidden impacts of society’s reliance on incarceration, discovered in a recent study that the average incarceration rate for the United States in 2014 was “716 out of 100,000 people”, whereas the rest of the world is around “155 out of 100,000 people” (Wyler). According to a report that examined the catastrophes of mass incarceration released by the White House, the U.S. prison population has increased 220% between 1980 and 2014 despite there being a drastic
The prison system in the United States has long been a topic of debate. Many people view prison as a dark blot on the character of our nation. However, many people view it as a justifiable, necessary evil that maintains the safety of the productive citizens of our society. As prisons are being filled to capacity, these two camps continue to argue whether more prisons should be built, or if the judicial system should relax the sentences upon lesser criminals. These two points, though valid, do nothing to remedy the real situation our nation faces, in dealing with an ever increasing prison population. While the number of people incarcerated has continued to rise, it has done little to curb the actual crime rate in America. This will continue
The U.S. corrections system has had a long history of being the most progressive in the world. It has been the model for many corrections systems around the world. From the invention of the modern prisons to the mission of Rehabilitation and modern probation. Even for most of the nineteenth and twenty century, the U.S. corrections remained in the lead for having the best ways to deal with offenders. However, even with all of the advances in the corrections system the U.S. is now know for having one of the most populated prisons in the world. In fact, since 1973, the U.S. imprisonment rate has increased from under 100 people per 100,000 to almost 500 per 100,000 (American Corrections, 2016).
