rryHonors Biology7 December 2017William Lawrence BraggWilliam Lawrence Bragg may not have been one of the scientists who directly discoveredDNA’s structure, but his research and findings shaped the future of science. He was born inAdelaide, South Australia in 1890. His parents were Gwendoline Bragg and William HenryBragg. His father was the Elder Professor of Mathematics and Physics at the University ofAdelaide. When he was young he broke his arm and his father used the earliest versions of x-raysto examine the break. This was the first use of x-ray for a medical use. After graduating highschool at age 14, Bragg began his studies at St. Peter’s College in Adelaide. When he was 16, hewent to the University of Adelaide to study mathematics, physics, and chemistry. He graduatedfrom the University of Adelaide in 1908. After this his father accepted an offer to be thecavendish chair of physics at the University of Leeds in England. The whole family then movedto england and Bragg entered Trinity College, Cambridge is the fall of 1909. He had received ahuge scholarship from Trinity even though he took the exam in bed while battling pneumonia.After initially excelling in math, he moved to study physics and graduated with first honors in1911.W. Gansereit 2He then started to work on x-ray crystallography with his dad. Working alongside his dadhelped Bragg because it gave him a start in the “industry” of science that his dad was alreadysubmerged in. The crystallography work that he did with the help of his dad gave him a jumpstart into working on other projects. Personally, I believe that working with someone can bebeneficial because the work may get done faster and you can have more than one perspective onsomething. However, working with someone can be troublesome because you could disagree ontopics or maybe disagree on how to do something which will hinder the task at hand. Bragg’s lawmakes it possible to calculate the positions of the atoms in a crystal from how an x-ray beam isdiffracted by the crystal lattice. His law is used in crystallography which is still used in sciencetoday. His crystallography work helped start the chain of events to discover the structure ofDNA. Using crystallography, Rosalind Franklin was able to find the image, Photo 51, whichhelped James Watson and Francis Crick developed the first DNA model. He also providedsupport to Francis Crick and James D. Watson who worked under his aegis at the Cavendish.Bragg also helped develop sound ranging in early WWI, which uses sound to determine thedistance and direction of the source or its reflector. Which later became sonar, which is a widelyused tool of modern day.With all of his work in mind, Bragg was highly awarded. He worked on crystallographyalongside his father, which won them the nobel prize in physics in 1915. Winning the prize at theage of 25, Bragg was, and still is the youngest laureate ever. He was also knighted in 1941 byKing Henry VI. Bragg was awarded the Hughes Medal of the Royal Society in 1931 and 1946.Awards such as these can create a “competition” between people to see who can do the best ordiscover something new. This can be beneficial because it will make people want to work harder3so that they will win the award. However, if someone is trying to just win an award they mighthave “tunnel vision” and not put detail into something just so that they can finish first.W
