Hydrogen Summary Essay Example for Free

Hydrogen Summary Essay * This is how hydrogen fuel cells work: 1. Gas stored in tanks 2. Atoms reach anode 3. Become hydrogen ion and a free electron 4. Ion goes through electrolyte layer 5. Hydrogen ion passes, but free electron does not 6. Free electron runs through external circuit from anode (-) to cathode (+) 7. Current of electrons creates electricity 8. Hydrogen ion enters cathode and combines with oxygen to become water which is better for the ecosystem because water vapor is not dangerous. * Why hydrogen as fuel? Efficient: not expensive to fill and it gives you more range. Emission Conscious: Hydrogen fuel cell cars release water vapor back in the atmosphere and don’t damage it by releasing C02 just like the other fuels. Fueling Up/Range: Since hydrogen is stored and highly compressed tanks it can hold more than any other fuel and has a bigger range. Global Economic Competitive Edge: Hydrogen is not as expensive as gasoline and it would cost you about  ½ of the money that you used to fill your car with gasoline to fill your car with hydrogen. * Better than other fuels: Hydrogen VS Ethanol: * Ethanol releases CO2 while hydrogen releases water vapor * Ethanol competes with the food producers(corn in the US, sugar cane in Brazil)and hydrogen doesn’t compete with anyone. * Ethanol is inefficient to produce while hydrogen is efficient. Hydrogen VS biodiesel: * Biodiesel solidifies in cold temperatures and it is harder to travel through the tubes(high viscosity) while hydrogen doesn’t solidify. * Biodiesel releases the most C02 out of all the fuels. Hydrogen releases water vapor * The range for biodiesel cars is 10% less than propanol cars . Hydrogen cars have 25% more range than biodiesel cars and 15% more than propanol cars. Hydrogen VS propanol: * Propanol has problems in high climates due to viscosity and the fuel solidifying while hydrogen cars don’t have problems with this. * Propanol releases C02 in the atmosphere, hydrogen releases water vapor. * The range for a propanol car is 15% less than a hydrogen car.

CNS Involvement in GBS: Brainstem Auditory Evoked Potential

CNS Involvement in GBS: Brainstem Auditory Evoked Potential BRAINSTEM AUDITORY EVOKED POTENTIAL AS AN INDEX OF CNS DEMYELINATION IN GB SYNDROME Dr. Smita Singh*, Dr. Nitesh Mishra**, Dr. Shraddha Singh#, Dr. Sunita Tiwari## ABSTRACT: Guillain-Barrà © Syndrome (GBS) is an acute, frequently severe and fulminant polyradicular neuropathy that is autoimmune in nature. GBS manifest as rapidly evolving areflexic motor paralysis with or without sensory disturbances. It mainly involves peripheral nervous system and autonomic nervous system. There are rare evidences about the involvement of central nervous system (CNS) in GBS. The main objective of the study was to assess the CNS involvement in GBS using the Brainstem Auditory Evoked Potential (BAEP). The study was conducted in the clinical neurophysiology lab in the department of physiology, CSMMU Lucknow. Study group involved 26 subjects (n=26) having GBS and control group involved 30 normal subjects (n=30). BAEPS were recorded by Neuroperfect- EMG 2000 EMG/NCV/EPsytem. The data so obtained were subjected to analysis using Statistical Package for Social Sciences (SPSS) Version 13.0. There was significant increase in PIII PV peak latencies and PI-PIII PI-PV interpeak l atencies in both left and right ear in the study group, which showed the CNS involvement in GBS which can be assessed using BAEP. Key words: Guillain-Barrà © Syndrome, Central Nervous System, Brainstem Auditory Evoked Potential INTRODUCTION: Guillain-Barrà © Syndrome (GBS) is an acute, frequently severe and fulminant polyradicular neuropathy that is autoimmune in nature. GBS manifest as rapidly evolving areflexic motor paralysis with or without sensory disturbances. The usual pattern is ascending paralysis i.e. weakness begins in distal limbs but rapidly advances to affect the proximal muscle functions. Lower cranial nerves are usually involved causing bulbar weakness and difficulty with handling secretions and maintaining airways. Deep Tendon Reflexes (DTR) usually disappears with in 1st few days of onset. Bladder dysfunction if present is usually transient1. In severe cases of GBS autonomic involvement is common. Usual feature are loss of vasomotor control with wide fluctuation in blood pressure, postural hypotension and cardiac dysrhythmias. Pain is another common feature of GBS most common is deep aching pain in weakened muscles. GBS shows mainly two types of pathophysiology, demyelinating form and axonal degeneration. Basis of demyelinating form is conduction block, which results in flaccid paralysis and sensory disturbances. Recovery is possible as remyelination occurs. Axonal degeneration shows slow rate of recovery and results in greater degree of residual disability. CSF shows albuminocytological dissociation that is elevated CSF protein level (100-1000gm/dl) without accompanying pleocytosis. CSF usually remains normal when duration of illness is less than 48 hours. CSF protein level increases at the end of first week of illness. Electrodiagnostic features are mild or absent in early stages and lag behind clinical evolution. Demyelinating form shows prolonged distal latencies, slow conduction velocities, conduction block and temporal dispersion of compound action potential. Axonal form shows decrease amplitude of compound action potential without conduction slowing and prolongation of latencies. There are several clinical, pathologic and electrophysiologic evidences that have established that GBS affects predominantly the peripheral nervous system. Focal demyelination of the Schwann cell derived myelin has been described. Neuropathologic and electrophysiologic evidences for involvement of central nervous system are rare. There are few studies2, 3, 4, 5, which have been performed to explore the involvement of CNS in GBS. However, there exists no study in the Indian environment regarding the same. The present study is an effort to explore the CNS involvement in GBS by measuring auditory evoked potentials. This test evaluates the integrity of auditory (Brainstem Auditory Evoked Potential) pathway by measuring evoked potentials. Evoked potentials are recorded as electronic impulses by surface electrodes attached to the scalp. A computer extracts these low amplitude impulses from background brain wave activity and averages the signals from repeated stimuli. Brainstem auditory evoked potentials, produced by delivering clicks to the ear, and help to locate auditory lesions and evaluate brainstem integrity. MATERIAL METHODS: The study was conducted in the clinical neurophysiology lab in the department of physiology, CSMMU Lucknow. The subjects of study group were selected from neurology, pediatrics and medicine department of CSMMU Lucknow and selection of the subjects of study group had been done on the basis of detailed history, though clinical examination, laboratory investigations and clinically proven cases of GBS. Normal healthy controls were selected after through clinical examination and it was insured that they do not have any apparent clinical illness that may affect the evoked potentials. Clearance from the institutional ethical committee was obtained written informed consent had been taken from the entire subjects study and control group. The study was conducted on clinically diagnosed cases of GBS of both sexes. The subjects were diagnosed on the basis of history, clinical examination, and typical CSF profile (albuminocytological dissociation) and electrophysiological evidences of demyelination. Subjects having prior neurological illness, apparent hearing and visual impairment, AFP due to another cause were excluded from the study group. All the subjects of study and control group were tested under similar laboratory conditions. Subjects were given sufficient time to relax rapport had been established so that they feel comfortable and cooperate during investigation Recordings of BAEPS: BAEPS were recorded by Neuroperfect- EMG 2000 EMG/NCV/EPsytem. The EPs were recorded with disc electrode from standard scalp location. Electrode were placed at vertex (Cz, reference electrode) ,ipsilateral and contralateral mastoid process (Ai and Ac active electrode) and forehead (Fz, ground electrode) after proper cleaning the scalp or skin site with alcohol followed by EEG conducting paste For recording 2000 click stimuli at the rate of 11Hz/sec with duration of .1 ms were delivered at 70 dB. The other ear was masked by pure white noise at 40 dB. This click generated by passing 0.1 ms square pulses trough shielded headphone. Electrical impedance was kept less than 5 kilo ohm. Peak latencies of all the waves I., II, III, IV and V and interpeak latencies of I-III,II-V and I-V were determined for both right and left ears separately. STATISTICAL ANALYSIS: The data so obtained were subjected to analysis using Statistical Package for Social Sciences (SPSS) Version 13.0. The data has been shown as mean ±SD, to compare the difference between the normal and healthy controls; â€Å"t† test for independent samples has been carried out. The confidence limit of the study was kept at 95%, hence a â€Å"p† value less than 0.05 denoted statistically significant difference. RESULTS: Table 1: Peak Brainstem Auditory Evoked Potentials for Left Right Ears ** p Table 2: Inter-peak latencies for BAEP for Left Right Ears * P DISCUSSION: Guillian Barre syndrome (GBS) is regarded as a predominantly motor neuropathy with transient or absent sensory features. Although the central nervous system is rarely involved, GBS associated with CNS, manifestations has been described in children by Okumura et. al (2002)6. and in adults by Maier H et. al. (1997)3, and Muller HD et. al.(2003)4 Maier H et. al. (1997)3 observed histopathological changes in CNS of GBS patients. He found infiltration of macrophages microglial cells and/or lymphocyte in different areas of central nervous system. Spinal cord and brainstem shows lymphocytic infiltration and microglial activation. Histopathological feature of CNS involvement is also observed by Muller HD et. al. (2003)4 in form of the cellular infiltration of spinal cord though not very significant and suggested CNS involvement in GBS occur, though rare. There are few studies which had demonstrated CNS (changes) lesion in GBS on neuroimaging. Nadkarni N et. al. (1993)7 observe MRI finding of CNS white matter lesion in patient of GBS who had developed symptoms of optic neuritis after plasmapharesis. These findings suggest there may be possibility of same antigenic mechanism of pathogenesis in CNS as well as peripheral nervous system. Okumura et. al. (2002)6 reported the clinical course and electrophysiological and neuroimaging of a patient of GBS associated with CNS lesion. He found mild slowing of background activities without paroxysmal discharge in electroencephalogram (EEG), mildly prolonged N2 latency with abnormal waveform in VEPs. BAEPs were unremarkable. In magnetic resonance imaging (MRI) there were multiple lesions in cortex and sub-cortex in the right occipital lobe and in the deep white matter in both frontal lobes. Despite all these lesions there was no evident CNS manifestation in the case. This implies that an association of CNS involvement in patients with GBS could be under estimated because some lesions can be clinically silent. The present study was an effort to evaluate central nervous system involvement in patients of GBS in Indian population because there is no study regarding the same performed in the India. In the view of known pathologic involvement of most proximal portion of peripheral nerves in GBS, the most likely cause of these BAEP abnormalities is focal demyelination of Schwann cell derived myelin sheath that covers the extramedullary portion of the auditory nerves. Prolongation I-III IPL indicative of lesion in the auditory nerve to medullary junction or lower pons around superior olive trapezoid body. The prolongation of I-V IPL suggests the abnormality of conduction of auditory signals from the proximal auditory nerve to the mesencephalon via pons. The findings of the study of BAEPs are comparable and show similarity with the results of study done by Zgorzalewicz M et. al. (2003)8 except there is an additional finding of IPL III-V prolongation in our study. In the study done by Schiff JA et. al. (1985)9 had also found prolonged I-III inter peak latencies (IPL) in five of six patients of GBS and I-V IPL in two of six patients, these results are comparable with the present study. Ropper AH et. al. (1986)10 also find the BAEP abnormality in the form of I-III and III-V IPL prolongation in patients of GBS, though that was not clinically significant. Whereas Nelson KR et. al. (1988)11, find the BAEPs abnormality in patients of GBS as prolongation of wave II latency and total absence of BAEM wave form in the early stage of disease and with the complaints of sudden onset of deafness, hearing improved with the recovery and BAEP abnormality of conduction block was replaced as a prolongation of wave I latency. After convalescent period BAEPs become normal. In present study there was no case present as similar complaint and BAEPs finding. Topcou M et. al. (1993)12 had performed evoked potential study in patients of GBS and found BAEPs and VEPs values were abnormal in some patients during early course of illness, though the values were not statistically significant. Wong V et. al. (1997)13 had found BAEPs abnormality in Miller Fischer syndrome (MFS), a variant of GBS. His findings of BAEPs abnormalities suggest proximal auditory nerve and brainstem involvement. CONCLUSION: Thus it can be concluded from our study that though often ignored, the central nervous system demyelination does occur in Guillain-Barrà © Syndrome (GBS) and the same can be assessed using evoked potentials like Brainstem Auditory Evoked Potentials (BAEP).

Why Might Freudian Therapy be a Waste of Time and Money Essay -- Psych

In his book Des Bienfaits de la Depression, Pierre Fà ©dida wrote a chapter called 'Il Faut Etre Deux Pour Guà ©rir' in which he explains why it is useful to talk when you are depressed.20 Patients usually believe that talking is not the solution but that the only way to cure is to bring back the lost person/situation whose absence initially caused the trauma. Psychological pain is a human particularity and therapy is meant to heal it. Fà ©dida uses the example of drug addicts who go on detoxification. Addiction to drugs often reveals an alarming state of depression and the fact of undergoing treatment for drug addiction is the sign of distress and will to be saved. Freud used to underline how human beings have created for themselves an interior metaphorical discourse to express extremely violent issues such as love, hate, life, death, sexuality...21 Analytical cure sight-reads this metaphorical language.

The therapist defines healing as the goal creating the patient's resistances. Thoses resistances to therapy can be explained as follows : the fact of being cured corresponds to a change of state.

Ben Jonsons On My First Sonne Essay -- Poem Ben Jonson First Sonne Es

Ben Jonson's On My First Sonne Ben Jonson writes On My First Sonne from a father’s point of view grieving over the death of his very young son. The title alone suggests which time period this poem is from i.e. it is from the 17th century (1603)- when the poet’s son Benjamin died- through the use of language of the time. This poem has been written in memory of a seven year old child whose death has dealt a great blow to a father. Throughout the poem, the use of religious comparisons and words creates a vivid picture of the thoughts running in the mind of Ben Jonson and we know almost exactly what he feels. The inter-relation of father and son in this piece of poetry leads us back to the beginning of the poem. The son, sitting on the right hand of his father, would remind a Christian reader of the Creed, in which the Son 'sitteth at the right hand of God the Father Almighty; From thence he shall come to judge the quick and the dead.' What others would interpret from the line-â€Å"Farewell, thou child of my right hand, and joy;† is that a father is bidding farewell to his most loved one and his heir. Again in line 2, when the poet says â€Å"My sinne was too much hope of thee, lov’d boy†, the poem suggests that Ben had taken his son much for granted as if now he possessed him and so loved him too much. It is ironical as he is comparing the love towards his son as a sin. As mentioned, he now considered that, love, his â€Å"sin† which has a deep meaning from a religious point of view. A sin, in the eye of GOD is a bad deed but in this case means a mistake or an error. The language used, hence in relation with religion, exclaims Ben Jonson’s sorrow and love for the child; despite the fact that he is in a way happy ... ...es of the poem. Contrastingly, in Refugee Mother and Child, the mother still showed her love and affection towards the child in the last few days. She cannot let go as easily. Most mothers would in this situation have lost hope and would have â€Å"ceased / to care†¦Ã¢â‚¬  but not her. She would ‘fight’ this sorrow till the end. Both poems hence clearly depict the true feelings about the death of a child. We get the perspective from two points of view in either case i.e. from a mother’s and a father’s point of view and the feeling before and after the death of a child. The language used is very specific and has been used in the most appropriate contexts. Sorrow and remorse are the main themes of both poems along with death of a child, yet there is another shadow of a theme i.e. the ‘sin’ of loving the child so much which causes almost endless grief in the end.

Analysis of the Movie, The Insider Essay -- Insider Movie Film Analys

The Insider (1999) is a film rife with ethical dilemmas, suspense and controversy. It is based on a true story related to a 1994 episode of the CBS news show 60 Minutes that never aired. The plot puts Dr. Jeffrey Wigand (Russell Crowe) at odds with Brown & Williamson, the third largest tobacco companies in the country. Wigand was fired from his position as Vice President of Research and Development, at which he was instructed to hide information related to the addictive nature of nicotine. The plot takes off when Lowell Bergman (Al Pacino), producer for 60 Minutes, discovers that Wigand has a story to tell. The best way for Wigand to tell that story is with the help of Bergman, via an interview aired on 60 Minutes. However, tobacco companies have a history of viciously defending their profits, by whatever means necessary, and Brown & Williamson does just that. The story hits a climax as the interests and incentives of the television station CBS, 60 Minutes, Dr. Wigand and Brown & Williamson are played out. Portrayal of Business The film portrays business in an extremely negative light. It focuses on two central conflicts – one between Brown & Williamson and Wigand, the other between CBS Corporation and Bergman. Brown & Williamson is the primary antagonist. The film is ripe with examples of the bad things they do. Their principle, most damaging offense is deceit. They are charged with covering up the addictive properties of nicotine and finding ways to exploit it to increase profits. For example, in Wigand’s interview for 60 Minutes, he says that tobacco companies view cigarettes only as a delivery device for nicotine. He also says they take advantage of the addictive properties by manipulating and adj... ...ons, the responsibility that power implies and the responsibility of media as a corporate watchdog. It seems obvious that large corporations have a tendency to ignore the negative effects of their actions in favor of profit. This example, although sensationalized, still says to me that with power comes responsibility. It affirmed my belief that a corporation’s goal cannot be just to provide profit to shareholders, but there must also be an element of social responsibility. It also made me think about media’s role in business. I think it should be just as portrayed in this film. Bergman relentlessly pursued the truth, using a very credible source. Too often today, media is spoon fed by corporations. Media has a responsibility to objectivity that can be important in keeping businesses honest. But, it’s really up to media to maintain that objectivity.

Identification of Morphological and Physiological Characteristics of Unknown Bacteria Essay

Obesity is a word that everyone is currently familiar with. The media and health professionals have been working tirelessly to make the general public aware of its prevalence and detriments to society. With the staggering statistics of 32.2% prevalence in adults and a range of 13.9% to 18.9% prevalence in children and adolescents, these outstanding numbers stand out for themselves. (1) Increasing rates of obesity are associated with higher risk factors for other diseases such as; Type 2 diabetes mellitus, cardiovascular diseases, colon cancer, diverticulitis, cancer of the endometrium, and breast cancer. (2) Knowing how to combat obesity will lead to decreased complications of the condition as well as a lower risk factor for other diseases. In light of these significant numbers, our group chose to explore the relationship of dietary fiber to aid in the prevention and treatment of obesity, therefore also reducing the incidence other diseases. Our focus was on making a hot meal with a simple modification to increase the dietary fiber available. The original recipe is a white rice pilaf with the adjustment being made with a substitution of brown rice. This change will boost the fiber intake from 0.8g per serving to 2.6g per serving. The represents a substantial jump in accessibility to a vital part of our diet. We expect favorable results in the acceptance of our modification. The texture is a bit hardier, cooking time is longer, and cost is slightly higher, but we believe the benefits outweigh these variables. The RDA recommends between 25g-30g a day, but the average American receives only 12g-13g per day.(3) With this easy alteration, we hope to increase these low numbers that the average American receives up to the reco mmended levels. Purpose The purpose of our research study is to substitute brown rice for white rice in a pilaf. This pilaf can be eaten for lunch or dinner as a hot side dish or main dish. It is intended to introduce a serving of a whole grain in the diet and with it bring an increase dietary fiber. Literature Review Introduction The frequent occurrence of this disease, as mentioned above, has produced many scientific research studies concentrating on remedying and reversing the trend. Finding and interpreting the results was uncomplicated. I used the online databases; Google Scholar, Medline, and Cinhal to gather my data. My keywords included obesity and dietary fiber. I assembled strong studies that encompassed sample sizes ranging from 11-74,091 participants, with timelines up to twelve years, and accommodating populations in the United States, Spain, Finland, Brazil, Italy, Greece, the former Yugoslavia, Japan, Serbia, Belgrade, and The Netherlands. These studies centered on three different aspects of the relationship between dietary fiber and weight. These are expanded upon below. A synopsis of the reviewed studies can be found in Appendix 1. Correlations of the Development of Obesity Seven out of the ten studies compared the connection between dietary fiber intake and the development or current status of obesity. (2, 4-9) All studies included self reported questionnaires to collect sociodemographic, health history, physical activity, anthropometric, bowel movements, and dietary data. The most common dietary form used was the Food Frequency Questionnaire, with six complying. (2, 4-5, 7-9) The last study utilized twenty-four hour recalls. (6) Other measurements included height, weight, and subscapular skinfold thickness. The entire body of findings revealed that higher fiber intake was inversely related to long term weight gain and increased body fat. Reporting measures were diverse but included the same positive trend. Higher fiber intake equated to an average weight of 1.52kg less, a 48-49% lower risk of weight gain, and a BMI that was 1.5 less when compared to low fiber intake. Some studies investigated other variables in addition to increasing fiber. One study addressed physical activity in addition to increased fiber as a therapy. (5) This study along with another explored the incorporation of a low fat diet along with the high fiber diet. In both, dietary fat was not directly associated with reduction of body fat or obesity but showed a compounding result when correlated with higher fiber. A lower BMI difference of 2.75 was established on a low fat and high fiber diet. (6) Development of Diseases related to Obesity Two studies were taken on to look into the increased use of fiber to decrease the risk of obesity leading to Type 2 diabetes. (10, 11) In a large cohort with a sample size just under 36,000, self reported dietary and weight figures were collected. (10) After six years of follow up, the statistics were analyzed and the results showed a 22% lower risk of the development of diabetes from the highest quintile of dietary fiber intake. These optimistic results were in consensus with the other study. This study had more stringent controls and divided participants into two groups. (11) One received standard care and the other received intensive exercise and dietary counseling. Oral glucose tolerance tests and body composition measurements were calculated. After a four year follow up, the high fiber group gained 75% less than their low fiber counterparts, 0.7kg gain versus 3.1kg gain, respectively. Treatment of Obesity The last study out of the ten engaged the most scientific disciplines. (12) The sample was already obese. They participated in controlled feeding in a metabolic kitchen. The cross over design allowed for six weeks on either a low or high fiber diet with a six week washout period in between them. Daily logs were kept and an OGTT and Euglycemic hyperinsulinemic clamp was used every two weeks for measuring results. At the conclusion, fasting insulin was 10% lower, the AUC was lowered, and the rate of glucose infusion was higher after the higher fiber diet. Limitations All of the studies employed self reporting figures in some form, whether the basis of all of their information or for at least some part. This may lead to underreporting, overreporting, or misinterpretation. The definition of a whole-grain or high fiber food varied among studies. Recipe and ingredient databases or non-comprehensive food frequency questionnaires may aid in inaccurate recordings of intake. Although the study utilizing the metabolic kitchen was the best scientific representation among the studies it is worth mentioning that it was sponsored and funded by the General Mills Corporation. This could lead to a possible conflict of interest and hence a limitation to the studies findings. Conclusion The complete compilation of studies supports the purpose of our recipe modification. Each emphasized the importance of replacing low fiber foods with fiber rich foods to help prevent or reduce weight gain. The significant correlation between fiber and obesity has been established in this review. The protective role of fiber, along with physical activity and dietary fat, should be included in advice and management therapies tailored to this condition and other related to it. Materials and Methods For our subjective evaluation we designed three separate score cards; demographic, evaluation, and preference. Samples of the score cards can be found in Appendix 2. Sociodemographic For the demographic background we included questions regarding age range, household income range, ethnicity, and educations. We also included six questions probing background information on exposure and open-mindedness of our products.

Inherit the Wind: Henry Drummond Essay

The authors, Jerome Lawrence and Robert E. Lee’s, main purpose through Inherit the Wind is proving that humans hold the right to think. Henry Drummond is vital in this discovery because of his firm belief that one should hold this right. Drummond’s hero archetype is the cause for his strong feelings, and he succeeds when convincing the audience of his beliefs by revealing the contradictions underlying his witnesses’ inherited religious beliefs. Henry Drummond arrives in Hillsboro as an atheist, and leaves as a hero. The townspeople’s initial reaction to the news that Drummond is defending Cates, alerts the audience. This is most apparent when Melinda, a young girl, first sees him and screams â€Å"It’s the Devil!† (Lawrence and Lee ). Drummond does not let the citizen’s misconstrued interpretation of him distract him from his goal, to take a stand. Drummond uses the case as an opportunity to fight for the right to think and develop one ’s own truths. Slowly the townspeople start to see through Brady and start to see the true Drummond. The Drummond who is committed to defending Cates and respects Cates for â€Å"standing up when everybody else is sitting down.†(Lawrence and Lee ). Brady and Drummond are alike in multiple ways such as their mutual respect for each other as well as their past together, but there are also very significant differences between them, such as their character. Drummond’s reason to defend Cates is to share a message throughout the world as well as protect an innocent man. Meanwhile Brady’s purpose is to gain popularity throughout the world, and only to help himself. Brady’s lack of dedication towards this case results in his downfall. In Act III of the play, the readers see Drummond’s quick mind, his ability to function under pressure, and his creativity. When the judge refuses all of Drummond’s witnesses he switches tactics and decides to call Brady to the stand a s an â€Å"expert† on the bible. Drummond’s character serves as a foil for Brady’s character, Drummond’s patient demeanor and open-minded, progressive way of thinking accentuates Brady’s narrow-minded way of thinking which causes the audiences support in his direction and opens their eyes to truth. The point where the Drummond’s point is finally made is when he stumps Brady. Drummond’s cross-examination of Brady causes humiliation and hysteria. Brady self-destructs when his convictions about the literal truth of the Bible are questioned and proved false due to Drummond. Drummond’s attack of Brady is not mean-spirited, it is  devastating. At the same time, the power of Drummond’s attack stems not so much from Drummond’s wit as from the weight of Brady’s egotism, stubbornness, and arrogance. Basically if Brady was not so cocky and arrogant he might have been able to prevent the case going the way it did. Although the trial in Inherit the Wind concerns the battle between creationism and evolutionism, a deeper conflict exists beneath the surface. Drummond points to this more basic issue when he asks his young witness Howard whether he believes in Darwin. When the boy responds that he hasn’t made up his mind, Drummond insists that the boy’s freedom to think—to make up his own mind—is what is actually on trial. This point in the book is where Drummond’s point becomes obvious; freedom of thought becomes the freedom to be wrong or to change one’s mind. Even though Cates is found guilty, Drummond wins a moral victory. He reveals his integrity when he defends freedom of thought, even for those he disagrees with. When Hornbeck criticizes Brady and Brady’s fundamentalist beliefs, Drummond tells Hornbeck that † . . . Brady had the same right as Cates: the right to be wrong† (Lawrence and Lee )! Drummond’s hero archetype and his initial analysis of Brady are the cause of his success with the people of Hillsboro. At the end of the play, Drummond feels the same way and is still fighting for people’s â€Å"right to be wrong† (Lawrence and Lee ).
