Any good chemist would understand that when Abraham Lincoln said “four score and seven years ago” he was actually using significant figures. The Declaration of Independence was signed on July 4th while Lincoln delivered this speech on November 19th. This means that it actually occurred four score, seven years, four months, and 12 days before. Admittedly that does not roll off the tongue as smoothly, so it’s understandable that Lincoln would only use two significant figures. Significant figures are the reason that the beginning lines of the Gettysburg address will forever be remembered by Eighth graders across the country. Without the use of significant figures, numbers in chemistry wouldn’t have any meaning. I could say 2g when I’m really …show more content…
If you are given a measurement of 4g and a measurement of 4.0001g, you would understand that the equipment used to measure 4.0001g is much more precise than the equipment used to measure 4g. Although significant figures tell us about the precision of the measurement, we really cannot attest to the accuracy of the measurement unless we are sure of the correct answer. The same rule about the estimated digit is applied when taking measurement. The way to report an analog measurement is to write down all the digits you are “confident” in and estimate one digit further. For example, if using a 10ml graduated cylinder with nine markings in between the numbers 1ml and 2ml and the liquid falls between 1.5ml and 1.6ml, but closer to 1.5ml, the digits you are confident in are 1 and 5. Therefore you estimate another digit which you think it could be such as 1.53ml. When making a digital measurement, the rule is to always write down every digit while understanding that the last digit is an estimation. There are also a few important differences between the course policy and the textbook. One is that the book states that if you place a $#$#0$#$# to the right of trailing zeroes, it would make those zeroes significant e.g. 500. has 3 significant figures while 500 has 1. This is not true and they should be ashamed. Another difference is in the convention of marking significant figures. In this course, Professor Halpin will underline all significant figures to identify them. It just makes it easier to get the correct answer while rounding to the correct number of significant figures. The book does not do

This speech, led by Abraham Lincoln, was a public address honoring those who have fallen as a result to the Civil War. Similar to the Pericles’ Funeral Oration, it was a dedication to soldiers and assured that their impact would not be in vain. Both of these speeches were delivered orally except that the address only occurred in one occasion. “Fourscore and seven years ago our fathers brought forth on this continent...”(citation) went onto a very memorable Abraham Lincoln quote. The Union Americans put less emphasis on the greatness of their military conquest in comparison to the Athenians. They focused more on the rights and equality of all men. They fought to defend their liberty and honor it, meanwhile the Athenians were declaring their love for their democracy. The democracy envisioned in America by the Union was more respectable and fair to all citizens as opposed to the Athenians which claimed to be equal voices by citizens but marginalized those who could become
The importance of significant figures in chemistry is that when doing any type of experiments, accuracy and precision is key. Being exact is extremely important during any sciences and math.
While the Gettysburg Address is fairly short in length at around 300 words, this famous speech delivered by President Abraham Lincoln on November 19, 1963 in Gettysburg, Pennsylvania is both enduring and meaningful for all Americans today, almost exactly 146 years later. The first paragraph of his speech sets the tone, in which Lincoln does not directly mention the bloody Battle of Gettysburg, in which 50,000 soldiers lost their lives. Instead, he refers in the opening phrase, “Four score and seven years ago,” to the founding of America through another important written document, the Declaration of Independence in 1776. I believe Lincoln wanted the country to focus on preserving this
The address has Biblical references as well, in the first six words: “Four score and seven years ago” (Lincoln 1). A shared language found in the Bible, particularly in the Psalms. Words such as devotion, hallow, consecration, new birth can be found other religious text and scriptures. In his last
Four and a half months after the Union defeated the Confederacy at the Battle of Gettysburg, Abraham Lincoln delivered the Gettysburg Address on November 19, 1863. He gave the Union soldiers a new perspective on the war and something to fight for. Before the address, the Civil War was based solely on states’ rights. Lincoln’s speech has the essence of America and the ideals that were put into the Declaration of Independence by the founders. The sixteenth president of the United States was capable of using his speech to turn a war on states rights to a war on slavery and upholding the principles that America was founded upon. By turning the Civil War into a war that was about slavery he was able to ensure that no foreign
In TMA02 I asked my tutor to give me specific feedback on the learning outcome Ky1. I was advised that I should take a little more care with significant figures and scientific notation. There has not been much emphasis on significant figures and scientific notation in TMA04. However I have taken the advice given by my tutor and broadened it to include attention to detail in all areas dealing with numbers within this assignment especially in questions 2 ai) 2ci) & 3bi).
The Declaration of Independence, a key to American beliefs, had been around for one hundred years, at this time. With this in turn, the celebration of being a free country and having civil rights was ringing about. Freedmen, former
Before 1864 Lincoln thought the best way to win the Civil War was to use a soft war strategy. General William T. Sherman’s Atlanta Campaign and March to the Sea were the beginning of a new era of warfare. He swayed Lincoln’s opinion to believe that the only way to win the war was to fight a total or hard war. This new war tactic was a major component of assuring Lincoln’s reelection in 1864. Without this, the outcome of both the election and the end of the war may have been much different.
A cannot be correct because as stated in the book America: A Narrative History, Lincoln said that Stephen A. Douglas was “…preoccupied only with the process (“popular sovereignty”)”. Therefore, the Lincoln-Douglas debates did not see Douglas abandon popular sovereignty, as this was what he was concerned with the most.
Four and a half months after the Union defeated the Confederacy at the Battle of Gettysburg, Abraham Lincoln delivered the Gettysburg Address on November 19, 1863. He gave the Union soldiers a new perspective on the war and a reason to fight in the Civil War. Before the address, the Civil War was based on states’ rights. Lincoln’s speech has the essence of America and the ideals that were instilled in the Declaration of Independence by the Founders. The sixteenth president of the United States was capable of using his speech to turn a war on states’ rights to a war on slavery and upholding the principles that America was founded upon. By turning the Civil War into a war about slavery he effortlessly ensured that no foreign country would
When it comes to the Gettysburg Address, Lincoln, wrote it within three days in July after the chaos that resulted in deaths and injured soldiers. Lincoln, believed that you can move forward after a loss by reminding the people (government) of principles that are bigger than just one person, give an accurate description of the mess that they're placed in, understand and acknowledge the sacrifices made, propose a rededication towards the main goal (mission), lastly, remind them again of the principles and how they're bigger than one person alone.
There is many important times from the past and many of them are very significant. One very important moment in history was when Abraham Lincoln was president because he changed many things that were very important. He was the United States 16th president. He believed like the constitution said that all men are created equal. He fought so that all the African Americans can be treated as equal as the white man. He was one of the people who changed the future for the African American people and it was really hard for him but he did what he could. Lincoln did want them to be treated as the white people but he didn’t believe that they should be equal politically. He didn’t want them to have the right to vote he just wanted them to be treated like
The time of the speech was towards the end of the civil war, when the North and the South where still fighting after a bitter 4 year war. The battle of Gettysburg had already been fought and Lincoln had given the distinguished Gettysburg address just a few months before. He spoke of freedom, devotion, and the ideals for which he believed the Union stood. Lincoln had also already written the emancipation proclamation which had freed the slaves of the south in the previous year. The audience which
Abraham Lincoln was considered by many American’s as one of the greatest Presidents of the United States. Having come from humble beginnings it could be said that Abraham Lincoln rose up to meet all the challenges that would greet him, and it could be argued that at the time the only person who could successfully guide the United States through the Civil War was Abraham Lincoln. At the time of his presidency, the United States was falling apart, with the South trying to secede from the North, creating much chaos that Lincoln had to deal with. He worked slowly and throughly, which sometimes got people agitated but he was a very careful working man and knew that it was better if he took his time. Abraham Lincoln was not
“I have never had a feeling politically that did not spring from the sentiments embodied in the Declaration of Independence.” Abraham Lincoln admired the declaration of independence and its founders. The Declaration of Independence was formed by the thirteen States of the confederacy. Represented by American liberty from each state. Twelve of these states where holders of slave. Abraham Lincoln legacy was for all men and women to be created equally. No matter what color or race you are, you have the right to life, liberty and the pursuit of happiness. It also states America’s freedom from Great Britain. What most people get wrong is that The Declaration of Independence wasn't signed on July 4, 1776. This was the date that congress Adopted
