J.B.S. Haldane An Evolution Biography

J.B.S. Haldane was an evolutionary biologist who made many contributions to the field of evolution. Dates: Born November 5, 1892 - Died December 1, 1964 Early Life and Education John Burdon Sanderson Haldane (Jack, for short) was born on November 5, 1892, in Oxford, England to Louisa Kathleen Trotter and John Scott Haldane. The Haldane family was well off and valued education beginning at an early age. Jacks father was a well-known psychologist in Oxford and as an eight-year-old child, Jack started studying the discipline with his father and assisted him in his work. He also learned genetics by breeding guinea pigs as a child. Jacks formal schooling was done at Eton College and New College at Oxford. He obtained his M.A. in 1914. Soon after, Haldane enlisted in the British Army and served during World War I. Personal Life After returning from the war, Haldane began teaching at the University of Cambridge in 1922. In 1924 he met Charlotte Franken Burghes. She was a reporter for a local publication and was married at the time that they met. She ended up divorcing her husband so she could marry Jack, almost costing him his teaching position at Cambridge for the controversy. The couple married in 1925 after her divorce was final. Haldane took a teaching position at the University of California, Berkeley in 1932, but returned to London in 1934 to spend the majority of the rest of his teaching career at the University of London. In 1946, Jack and Charlotte separated in 1942 and finally divorced in 1945 so he could marry Dr. Helen Spurway. In 1956, the Haldanes moved to India to teach and study there. Jack was openly atheist as he said that was how he conducted his experiments. He felt it wasnt fair to assume no God would interfere with the experiments he conducted, so he could not reconcile having a personal belief in any god. He often used himself as a test subject. Jack allegedly would perform dangerous experiments, such as drinking hydrochloric acid to test the effects on muscle control. Career and Accomplishments Jack Haldane excelled in the field of mathematics. He spent most of his teaching and research career interested in the mathematical side of genetics and particularly how enzymes worked. In 1925, Jack published his work with G.E. Briggs about enzymes that included the Briggs-Haldane equation. This equation took a previously published equation by Victor Henri and helped reinterpret how enzyme kinetics worked. Haldane also published many works on population genetics, again utilizing mathematics to support his ideas. He used his mathematical equations to support Charles Darwins idea of Natural Selection. This led to Jack helping to contribute to the Modern Synthesis of the Theory of Evolution. He was able to link Natural Selection to Gregor Mendels genetics using mathematics. This proved to be an invaluable addition to the many pieces of evidence that helped support the Theory of Evolution. Darwin himself did not have the privilege of knowing about genetics, so a quantitative way to measure how a population evolved was a major breakthrough at the time. Haldanes work brought a new understanding and renewed support of the Theory of Evolution by quantifying the theory. By using quantifiable data, he made the observations by Darwin and others verifiable. This allowed other scientists across the world to use their own data in support of the new Modern Synthesis of the Theory of Evolution linking genetics and evolution. Jack Haldane died December 1, 1964, after a bout with cancer.

The First Law Of Thermodynamics - 1618 Words

First law of thermodynamics According to the first law of thermodynamics, the amount of energy given in a system remains the same the entire time. You are allowed to transfer the energy but it is impossible to create or destroy energy. If I was to take a tennis ball and hold my arm out at a 90 ° angle, then release the ball there is no possible way the ball would go higher than where it started. This important with energy policy because in order to learn how to make energy more efficient and cost effective you have to understand what is physically possible to accomplish. Energy security Energy security is the nonstop accessibility of energy sources at an inexpensive price, To provide solid economic growth and to maintain high levels of economic performance, energy must be readily available, affordable and be able to provide a reliable source of power without vulnerability to long or short term disruptions. Interruption of energy supplies can cause major financial losses and create chaos in economic loss as well as potential damage to the health and wellbeing of the population. Unconventional oil The U.S. Department of Energy divides unconventional oil into four types: heavy oil, extra heavy oil, bitumen, and oil shale.

Metamorphosis The Outsider Comparison Essay Example For Students

Metamorphosis The Outsider Comparison Essay * Franz Kafka writes with a unique style in Metamorphosis giving the reader a very anxious and tense feeling. Kafka achieves this by writing in very short and choppy sentences that reflect the thought process of Gregor. Along with these short, choppy sentences, Kafka includes a series of rhetorical questions showing the wild course Gregors mind goes through to make every minor decision as quickly as possible. * The Outsider is conversely written in a structure that creates a feeling of a lack of true emotion. Albert Camuss writing reflects the routine of Mersault and portrays a sense of normalcy within a very mournful situation. This is shown when Mersault is on his way to his mothers funeral and Camus writes that he routinely stops a restaurant to eat. This nonchalant writing style is different then Kafkas style where one shows abundance or overwhelming emotion and the other shows a lack of emotion in a very mournful time. * Kafka and Camus also differ in their writing tenses. In Metamorphosis, Kafka shifts from third-person to first person, in the first paragraph, and then continues on with third-person. These tenses go along with the style of showing the though process of Gregor and it gives a reader and outside as well as inside perspective into his thoughts. * The Outsider on the other hand is written primarily in the first person tense. Camus is able to the take the reader through Mersaults thoughts in his perspective, which lends to an added bias in feeling and emotion. Mersault does not show much emotion during the time of his mothers death because he has not been a part of her life in recent years and Camus is able to successfully show that because he uses 1st person tense and is able to portray bias in emotion. * The tone of both passages also differs. Metamorphosis portrays an anxious and worrisome tone. In Metamorphosis, Gregor randomly evolves into an insect and he discovers the many difficulties that come with that lifestyle. This abrupt evolution creates a tone of worry and anxious feelings because Gregor is confused and does not know what to in his current situation. Also, the added pressure from his parents and sister to support for the family creates a tone of worry. Because he is not able to perform his duties for the family and go to work to pay back debts, the tension is increased and he begins to become more panicked and worried. * The Outsider portrays a nonchalant tone mainly as a result of the attitude of the character Mersault. Throughout the first excerpt, Mersault continues to show his lack of emotion towards his mothers death, which is a very unusual phenomenon. Gregor continues his daily routine of eating at the usual restaurant despite the tragedy in his family. He also feels that it would take to much effort to visit his own mother and this along with other actions create a nonchalant tone that carries through this excerpt.

William Shakespeares The Taming of the Shrew Essay Example For Students

William Shakespeares The Taming of the Shrew Essay William Shakespeares The Taming of the Shrew raises many important issues, reflecting the context of the times it was composed and their values. In its modern 20th century reproduction, 10 Things I Hate About You, many of these issues are appropriated into different and also similar values and themes with the same relevance it has in the society.  The Taming of the Shrew is one of Shakespeares earliest comedies, focusing on courtship and marriage, while also sharing the essential characteristics of a romantic comedy disguise, deception, slapstick humour and a happy ending. The concerns of married life and in turn the roles of men and women in the society, would have been particularly relevant to English audiences of the Elizabethan times. We will write a custom essay on William Shakespeares The Taming of the Shrew specifically for you for only $16.38 $13.9/page Order now An important issue regarding Elizabethan marriages of mainly upper class society would have been the motives behind these: that being money, land and power. In the play, Baptista chooses the suitor to his daughter Bianca by their offer of wealth.  Tis deeds must win the prize, and he of both  That can assure my daughter the greatest dower  Shall have my Biancas love. (line 331, Act II, Scene 1). Thus, what you own and acquire in a marriage pre-determined the outcomes of marital disputes in such a society. However, 10 Things introduces a more suitable and readily accepted theme love. The thought of marriage for wealth and power and purchasing a wife, today, is something greatly frowned apon. In the film, the payment of Patrick Verona (Heath Ledger) to date Katherina Kat Stratford (Julia Stiles) was seen as something extremely offensive and wrong, while Bianca freely chose her date out of attraction and love. This illustrates the changed values and nature of relationships between men and women since the 16th century. It seems that Shakespeare confirms the traditional view that men should dominate and that women should submit to their authority in his play, The Taming of the Shrew. All the characters, excluding Katherina, appear to agree on the assumed social roles of gender and that her shrewish behaviour is unacceptable. Yet, in the end she had transformed and even gave a speech proclaiming female submission and male dominance. thy lord, thy king, thy governor  Thy husband is thy lord, thy life, thy keeper,  Thy head, thy sovereign; (Line 146, Act V, Scene II)  However, in the film appropriation, male dominance is reduced to an equilibrium and alternatively focused on the strong positive womens roles. Although the father, Walter (Larry Miller), still has responsibility and authority of his daughters, it is different to the Baptistas prerogative. The father is playing a paternalistic role. The daughters fall as victims of the power the father possesses and the rules he determines and enforces. Yet this power is minimised in the film and he becomes the spectator in his daughters lives. You know, fathers dont like to admit it when their daughters are capable of running their own lives. It means weve become spectators. Bianca still lets me play a few innings. Youve had me on the bench for years. He says to Kat. This suggests the ways and levels that parents have come to understand of accepting individuality and independence of their children, where in the film, the father finally accepts Kats independence and approves her studying at Sara Lawrence. In many Shakespearean works, the father is often entitled to give his daughter away in marriage to whoever he prefers. Since patriarchal values have since then been abandoned and today, we adopt the idea of equality of the sexes and the shifting roles of women in a society. Shakespeares audience expected the idealised woman to be acquiescent, passive and below their husbands foot. However, Bianca from 10 Things is admired not for these reasons. .uc7e949f2e010e1d3aa6d326bb419280b , .uc7e949f2e010e1d3aa6d326bb419280b .postImageUrl , .uc7e949f2e010e1d3aa6d326bb419280b .centered-text-area { min-height: 80px; position: relative; } .uc7e949f2e010e1d3aa6d326bb419280b , .uc7e949f2e010e1d3aa6d326bb419280b:hover , .uc7e949f2e010e1d3aa6d326bb419280b:visited , .uc7e949f2e010e1d3aa6d326bb419280b:active { border:0!important; } .uc7e949f2e010e1d3aa6d326bb419280b .clearfix:after { content: ""; display: table; clear: both; } .uc7e949f2e010e1d3aa6d326bb419280b { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uc7e949f2e010e1d3aa6d326bb419280b:active , .uc7e949f2e010e1d3aa6d326bb419280b:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uc7e949f2e010e1d3aa6d326bb419280b .centered-text-area { width: 100%; position: relative ; } .uc7e949f2e010e1d3aa6d326bb419280b .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uc7e949f2e010e1d3aa6d326bb419280b .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uc7e949f2e010e1d3aa6d326bb419280b .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uc7e949f2e010e1d3aa6d326bb419280b:hover .ctaButton { background-color: #34495E!important; } .uc7e949f2e010e1d3aa6d326bb419280b .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uc7e949f2e010e1d3aa6d326bb419280b .uc7e949f2e010e1d3aa6d326bb419280b-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uc7e949f2e010e1d3aa6d326bb419280b:after { content: ""; display: block; clear: both; } READ: What use of the supernatural does Shakespeare make EssayAlthough adopting the identity as the ideal woman empowers both Biancas with popularity, the definition and values of ideal has ever since changed as the film illustrates the perception of ideal young women as beautiful and fashionable.

She was branded as a shrew a name, in the Patriarchal society, used to indicate a domineering, sharp-tongued woman or those who resist the assumed authority of their husbands.  Not only is the freedom that Kat acquires in the film is particularly significant, but the degree that she submits and conforms is also relevant. In the Taming, Katherina was tamed from a wild Kate to a Kate  Conformable as other household Kates. (Line 269, Act II, Scene 1)
