A hypothetic body that completely absorbs all wavelengths of thermal radiation incident on it. Such bodies do not reflect light, and therefore appear black if their temperatures are low enough so as not to be self-luminous. All blackbodies heated to a given temperature emit thermal radiation with the same spectrum, as required by arguments of classical physics involving thermal equilibrium. However, the distribution of blackbody radiation as a function of wavelength, known as the Planck law, cannot be predicted using classical physics. This fact was the first motivating force behind the development of quantum mechanics.

Benjamin Solomon "Ben" Carson, Sr., (born September 18, 1951) is a columnist and retired neurosurgeon. He is credited with being the first surgeon to successfully separate conjoined twins joined at the head. In 2008, he was awarded the Presidential Medal of Freedom by President George W. Bush. After delivering a widely publicized speech at the 2013 National Prayer Breakfast, he became a popular figure in conservative media for his views on social issues and the federal government. Early life Carson was born in Detroit, Michigan, the son of Sonya (née Copeland), a Seventh-day Adventist; and Robert Solomon Carson, a Baptist Minister.[1] His parents were both from rural Georgia.[1] At 8, his parents divorced and he and his 10- year-old brother, Curtis, were raised by their mother.[2] He attended Southwestern High School in Southwest Detroit, and graduated from Yale University, where he majored in psychology. He received his M.D. from the University of Michigan Medical School. Medical career Ben Carson Carson was a professor of neurosurgery, oncology, plastic surgery, and pediatrics, and he was the director of pediatric neurosurgery at Johns Hopkins Hospital.[3] At age 33, he became the youngest major division director in Johns Hopkins history, as director of pediatric neurosurgery. He was also a co-director of the Johns Hopkins Craniofacial Center. According to Johns Hopkins Hospital literature, "Dr. Carson focuses on traumatic brain injuries, brain and spinal cord tumors, achondroplasia, neurological and congenital disorders, craniosynostosis, epilepsy, and trigeminal neuralgia. He is also interested in maximizing the intellectual potential of every child."[3] Carson believes his hand-eye coordination and three-dimensional reasoning skills made him a gifted surgeon.[4] After medical school, he became a neurosurgery resident at Johns Hopkins Hospital in Baltimore. Starting off as an adult neurosurgeon, Carson became more interested in pediatrics. He believed that with children, "what you see is what you get, ... when they're in pain they clearly show it with a frown on their face or when they are happy they show it by smiling brightly.[4] " In 1987, Carson successfully separated conjoined twins, the Binder twins, who had been joined at the back of the head, making them craniopagus twins. The 70- member surgical team, led by Carson, worked for 22 hours. At the end, the twins were successfully separated and can now survive independently. As Carson wrote in his book: “ ...they would always exsanguinate. They would bleed to death, and I said, 'There's got to be a way around that... I was talking to a friend of mine, who was a cardiothoracic surgeon, who was the chief of the division, and I said, 'You guys operate on the heart in babies, how do you keep them from exsanguinating' and he says, 'Well, we put them in hypothermic arrest.' I said, 'Is there any reason that – if we were doing a set of Siamese twins that were joined at the head – that we couldn't put them into hypothermic arrest, at the appropriate time, when we're likely to lose a lot of blood?' and he said, 'No way.' ...two months later, along came these doctors from Germany, presenting this case of Siamese twins. And, I was asked for my opinion, and I then began to explain the techniques that should be used, and how we would incorporate hypothermic arrest... And, my colleagues and I, a few of us went over to Germany. We looked at the twins. We actually put in scalp expanders, and five months later we brought them over and did the operation, and lo and behold, it worked.[5] ” Carson figured in the revival of the hemispherectomy, a drastic surgical procedure in which part or all of one hemisphere of the brain is removed to control severe pediatric epilepsy. He refined the procedure in the 1980s, encouraged by Dr. John M. Freeman,[6] and performed it many times.[7][8] In addition to his responsibilities at Johns Hopkins, he has served on the boards of the Kellogg Company, Costco, and the Academy of Achievement. He is an emeritus fellow of the Yale Corporation. In March 2013, Carson announced he would retire as a surgeon, stating "I'd much rather quit when I'm at the top of my game, and there's so many more things that can be done."[9] His retirement became official on July 1, with Carson saying he would leave the decision of whether to go into politics "in the hands of God, but much can be done outside the political arena."

Feeds Feeds No! “I can’t take this anymore. This is too much for me ”. This were the words spilling out of Bisi’s mouth as she scanned through the notice board.She has just failed the M.B.B.S part II exams for the third time. Since Bisi’s childhood days, she had always dreamt of becoming a doctor. She loved doctors! She loved the sight of them, the smell of them, everything about them. Seeing those (doctors) in their immaculate white ward coat, as she made her way to school every morning gave her copious joy that carried her through the day. There was this one time she had the privilege of having a one-on-one chat with the chief medical director of one of the hospitals in her neighborhood, during her school’s visit to the hospital; she was frenzied the whole time. She couldn’t stop talking about it. Bisi, on her part didn’t do badly. She was the best in her class and had bagged various awards for her excellent performance both in national and international competitions. Chief and Mrs Adebola; Bisi’s parents were indeed the proudest parents around. Bisi was the last of four children yet she showed a very high sense of responsibility. She became an object of reference for other parents who often pointed her out to their kids as someone to be emulated. By the time she finished from secondary school,she went ahead to take the Joint Admission and Matriculation Board (JAMB) exams. She passed it as usual and proceeded to attend the screening exams into the prestigious University of Ibadan.She emerged as the best student and she was granted scholarship to study Medicine and Surgery. Wow! Here she was.Her dreams of becoming a doctor was just a hair’s breath away.She was indeed excited.She worked tenaciously to make sure she came out best. She went to classes day in, day out. In the day,to attend lectures and at night (popularly called AWOKO or TILL DAY BREAK) to read her books. She never bothered making flamboyant hairstyles or even applying a make up. To her, all that was a complete waste of time. She was that serious! . In the third year of her stay in the university, tragedy struck. She took her final pre-clinical exams (popularly know as M.B.B.S ) for the first time and failed! . She was furious. “It can’t be! How could I ? . I have worked too hard to be hit by this kind of bad luck” She said. She complained and complained,but at the end she was calmed by her colleagues and was advised to concentrate on the re-sit exams. She took the re -sit exams reluctantly feeling she deserved better. But as if the god of failure had made a tent in her hostel room; she failed again! She was a psychological wreck knowing full well that she only had one last go at the exams.Her dreams of becoming a doctor were becoming bleak. She had to do something about her failing streak. She intensified her study and hardly even took a bath. Her forth coming exams became the subject of her nightmare. Even her so called friends and colleagues began to ridicule her. All these while,she had the backings of her family. They still had faith in her despite her recent misfortune. However, her dad’s patience began wearing thin. He couldn’t comprehend how his beloved daughter,the apple of his eyes had missed it. He had bluntly said he was disappointed in her to say the least. This really mounted pressure on her and put her at the brink of collapse.The time eventually came for her to write the exam and she did. The long awaited results of the re- sit exams was finally pasted on the notice board.Everyone who had taken the exams rushed to the notice board to check their results including Bisi. Lo and behold, Bisi had failed for the third time. This was the last straw that broke the Carmel’s back. She screamed and shouted “I can’t take it anymore. This is too much for me. No!!!!!!!!!!!!!! “. How was she going to break the news to her parents.Her whole world was crashing down in front of her and there was nothing she could do. The thought of leaving medical school sent chills down her spine. This is all she had lived for. She would probably die a day without it. Suddenly, a thought ran through her mind; “Yes! I am going to end it all”. She ran as fast as her legs could carry her to her hostel. She rushed into her room,grabbed her bag, took out some drug and popped out ten tablets. “This is it! I would rather kill myself than living one more day which in itself is death”. She threw the tablets into her mouth and soon afterwards fell to the ground. She felt life being snuffed out of her. Suddenly,she heard a voice “Honey! … Honey wake up”. The voice was familiar. It was her husband’s. “Sweetie you are gonna be late for work,” the voice said. She opened her eyes and saw her husband sitting by her. He has been shaking her vigorously for the past ten minutes. She got up, smiled and burst into uncontrollable laughter. Her husband kept on wondering why she had choose to laugh in that manner in the early hours of the morning. He smelled his breathe and said to her ” Honey, is everything OK ? Does my breathe stink that bad? ” . She then smiled and replied “Sweetie you won’t believe the dream i just had. Don’t worry i will tell you all about it when i get back from the office”. She rushed into the bathroom,prepared and hurried off to work. On arriving her workplace,she walked briskly into her office and shut the door behind her to reveal the inscription ” DR. ADEBOLA BISI,CONSULTANT GYNAECOLOGIST “.
You are at a meeting of a religious nature when it devolves upon you to speak. There are a few general suggestions that will be of help to you. In the first place, notice the following negative suggestions : 1. Do not speak at great length. It is not fair for you to occupy an undue share of time. As the meeting is necessarily short you should make your remarks very brief. 2. Do not speak too personally. A public meeting is almost never the place for intimate revelations. Maintain a certain degree of reserve. 3. Do not present any controversial topic. A meeting of religious nature is not the place for controversy. 4. Do not speak in bitterness or in contempt of anything or anybody. A meeting of religious nature is the place for good will. 5. Do not speak egotistically or boastfully. A religious meeting is the place for humility. On the other hand, you should observe the following rules: 1. Speak briefly. 2. Speak quietly and reverently. 3. Maintain a certain reserve. 4. Speak so that all will agree with you. 5. Speak kindly of everything. 6. Speak with humility. 7. Present one leading thought, and only one. Form this thought in accordance with the spirit of the meeting. If any general thought has been given for discussion be sure that your topic comes under the leading topic. If you try to present more than one leading thought you will not be able to present it clearly in the short time at your disposal. You can present one thought clearly and emphatically. 8. Give one or two examples to prove your main assertion. Make these examples as specific as possible. Give names, places, and dates, or any other specific and exact references. 9. Conclude by repeating your main assertion in some emphatic form. By doing this you show that your talk has had one object, and that you wish all thought centered on your theme.
In the deep, dark ocean, viruses have won safe harbor through thievery. With stolen genes that make sulfur- digesting enzymes, viruses provide metabolic backup to bacteria feasting on the sulfur plumes of hydrothermal vents, researchers propose May 1 in Science. In return, the viruses secure a host in the harsh depths of the sea. Though the oceans are rife with bacteria-infecting viruses, called bacteriophage, researchers know little about the ones that invade sulfur- oxidizing bacteria. These bacteria are key sources of energy for organisms that live in hydrothermal vents. But the bacteria are difficult to study because they don’t grow in labs. Geomicrobiologist Gregory Dick of the University of Michigan in Ann Arbor and colleagues spotted the genetic looters in samples from vents in the western Pacific Ocean and the Gulf of California. By sequencing DNA in each sample, the team found the genomes of sulfur-oxidizing bacteria and 18 types of viruses. Fifteen of these viruses, the researchers found, had snatched and held onto bacterial genes involved in converting elemental sulfur to sulfite, a necessary step in energy production. By toting these filched metabolism genes, the authors suggest, the viruses bolster the host bacteria’s energy output.
