serendipitous‚ either by means of trying to create artificial chemicals‚ failing and creating something accidental‚ or just by plain dumb luck. Most of the discoveries and expansions of nitro compounds has to do with luck. One account of pure randomness is when Christian Friedrich Schöbein spilled a mixture of nitric acid and sulfuric acid on his wife’s apron. When he hung it to dry‚ he had converted the cellulose in the apron as an internal source of oxygen; when heated‚ it exploded. Phenols

Niyi Osundare: Not My Business This poem is about shared responsibility and the way that tyranny grows if no one opposes it. It is composed‚ simply‚ of three stories about victims of the oppressors‚ followed by the experience of the speaker in the poem. The poet is Nigerian but the situation in the poem could be from many countries. It echoes‚ in its four parts‚ a statement by Pastor Martin Niemöller‚ who opposed the Nazis. Speaking later to many audiences he would conclude with these words‚ more

Tone is a matter of great importance in writing‚ and is a key feature in any work of literature. Furthermore‚ it’s crucial in determining the deeper meanings of rhetorical writings as well--such as my letter to Mr. Wagner and my letter to Arne Duncan. Each paper has its own uniques style of how it wants to presents ideas‚ and this type of writing--also known as voice--is determined through the identification and analysis of context‚ audience‚ and purpose. For example‚ my letter to Mr. Wagner can

Examining market efficiency in India: an empirical analysis of the Random Walk Hypothesis Alan Harper South University Zhenhu Jin Valparasio University ABSTRACT This study tries to determine whether the Indian stock market is efficient by examining if the stock returns follow a random walk. Following previous studies‚ we use autocorrelation‚ the Box-Ljung test statistics and the run test and find that the Indian stock market was not efficient in the weak form during the testing period.

The randomness governing the denoument of a research study could be equated with that involving the outcome on flipping a coin.It could result in a tails or heads with equal probability.That is‚to be or not to be‚is in the hands of the forces of the universe figuratively

ammonium nitrate that is considered an explosive by the exothermic reaction. “Many chemical reactions release energy in the form of heat‚ light‚ or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy. In the lab‚ exothermic reactions produce heat or may even be explosive (Helmenstine‚ 2017).” An example of exothermic

Black Swans or Dirty Ducks? A Retrospective Challenge the Unchallenged It’s a duty of risk managers to challenge that which rests unchallenged. Nassim Nicholas Taleb did a great service by popularizing risk concepts in his book‚ The Black Swan . However‚ it is easy to get seduced by his enthusiasm‚ carried away by his pace and miss a few flaws. Over the last six years since it was published The Black Swan has been virtually unchallenged as a standard reference book. However‚ on closer examination

describe its behavior. Models may also be classed as either deterministic or probabilistic. A deterministic model always performs the same way under a given set of initially occurring conditions‚ while a probabilistic model is characterized by randomness. Another way of evaluating models is to determine whether it is static or dynamic. Static models do not account for time‚ while dynamic models do take this element into consideration. In calculus‚ dynamic models are often represented using

probability uses the same range of values‚ in every variables in each form of distributions. Probability Model is a stochastic model that shares a similar mathematical formulation with deterministic model that incorporates the same element of randomness‚ via contrasts and comparisons relying on predictions based on observation regarding each variable. Gaussian is the simplest probability model that operates and observes the Gaussian distribution‚ whether; it is through biology‚ medicine or public
