Acceptance Speech I am sorry my uncle could not make (he is dead) it I will represent him. My Uncle DeMorgan’s is a great and powerful yet successful man at what he does. Here is some of my uncle’s background (history). Augustus De Morgan was born on June 27, 1806 in
India. He was an Indian-born British mathematician. (Wikipedia. “Augustus De Morgan.”18 October 2006. 5 December 2006 <http://en.wikipedia.org/wiki/Augustus_De_Morgan>) De Morgan’s observation influenced everyone across the world, the algebraisation of logic taken over by George Boole, which cemented Morgan’s claim to the find of logician. (cf. Bocheński’s History of Formal Logic. 4 Dec. 2006) one achievement would be that he came up with the law known as De Morgan’s law and was the first to introduce it. Augustus was a very honorable and great uncle to be around. Anyway another achievement was that the De Morgan crater on the Moon is named after him which I am so very proud of. My uncle went to
Trinity College England when he was only 16 years of age. He immediately came under the influence of George Peacock and William Whewell. They became his life-long friends; from then on he resulted in the interest of algebra and from the interest in logic—the two subjects of his future life work. My uncle then died on March 18, 1871 due to a nervous prostration. This was overly upsetting. Anyway another achievement would be that my uncle got his degree in Bachelor of Arts, in which I was exceedingly impressed and overly proud of him for what he had accomplished even though I was not born. At the prestige’scollege of
Oxford and
Cambridge which at that point did not allow any Jews or Dissenter. My great uncle taught at a new college that opened up in
London at just the young age of 22 my uncle was a professor of Mathematics and some of his studies are still used to this day. Another interesting fact about my uncle was that he received his secondary education from Mr. Parsons, a professor of
Oriel
College,
Oxford, who appreciated classics much rather than mathematics. Another interesting, but dishearten fact was that my uncle had no job opening’s available at his college. Which sooner rather then later, he got another job which was teaching in
London. I would now like to thank my Uncle’s mother and father even though they could not be here (dead) which was disheartening. I would also like to thank my uncle for teaching me while he was still alive how to do math and the importance of math in life experiences. He was such a loving and great uncle to me and I am deeply saddened by the fact he was unable to attend this great ceremony (Mathematicians Hall of Fame). I dearly miss him…….. I would also like to thank the people that will hopefully vote him in to the Hall of fame of Mathematics. (Even though he was chosen to the induction of the hall of fame) I would also like to thank my relatives for showing up for the ceremony of my uncle Augustus De Morgan. An hopefully he will be voted in!!!! He sure deserves it. (Wikipedia. “Augustus De Morgan.”18 October 2006. 5 December 2006 <http://en.wikipedia.org/wiki/Augustus_De_Morgan>)
1)
A. n /\ ( d \/ c ) = 107 B. ( n /\ d ) \/ c =18,498 C. n /\ d \/ c = 107 D. ( n /\ d) \/ ( n /\ c)=18,498
2) A and C both have the same number hits which is 107 because they have the same search criteria with the same words and the parenthesis don’t matter when it comes to searching. B and D have the same number of hits which is 18,498 because they have the same number of hits because there searching has the same names with both “And” and “Or” in the same order.
3) My job for Part 3 was to find out how my searchs compared to van digrams and here are the ways they turned out
Professor Glass did say that these assignments were ment to be applied to real world searches, so I used Google for these search strings…
When entering a search string with Google, they give you the helpful hint of capitalizing ”OR”, as well as including “AND” by default; Though I did include it anyway.
a. N ^ (D V C) = “New York State” AND
(“Death Penalty” OR “Capital Punishment) 377,000
b. (N ^ D) V C = (“New York State” AND “Death Penalty”) OR “Capital Punishment” 377,000
c. N ^ D V C = “New York State” AND “Death Penalty” OR “Capital Punishment” 377,000
d. (N ^ D) V (N ^ C) = (“New York State” AND “Death Penalty”) OR (“New York State” AND “Capital Punishement”) 119,000
N ^ (D V C), (N ^ D) V C, and N ^ D V C all came up with the same number of hits (377,000) because they all are searching the same content, though parenthesis are put in different places, and in one instance is not used at all. In other words, they all mean the same thing though they look a bit different.
Venn Diagram C
I found that Venn Diagram (C) corresponds to N ^ (D V C), as well as (N ^ D) V (N ^ C).
Venn Diagram B
I found that Venn Diagram (B) corresponds with (N ^ D) V C, as well as N ^ D V C.

(Database: Project Muse)
(1A) “New York State” and (“death penalty” or “capital punishment”) = 26 hits
(1B) (“New York State” and “death penalty”) or “capital punishment” = 371 hits
(1C) “New York State” and “death penalty” or “capital punishment” = 371 hits
(1D) (“New York State” and “death penalty”) or (“New York State” and “capital punishment”) = 26 hits
(2) Statements that yield same results & why?: A&D and B&C. Due to database feature and statements are equivalent.
(3) Corresponding Venn Diagrams: Statements A&D = Venn Diagram C. Statements B&C = Venn Diagram B

2) In part 1, which searches yield the same results and why?
In part one, the searches that yield the same results is A and C, because they both are searching for the same result of death or capital punishment and the search is the same except that the parenthesis makes the search look different when it is really the same search.
3) For each of the searches above, determine which Venn diagram corresponds to the search:
a) Search A corresponds with Venn diagram C, because it includes everything but excludes the A, and B search.
b) Search B corresponds with Venn diagram D, because it includes everything in A, B, and C.
c) Search C corresponds with Venn diagram D, again because it includes everything in A, B, and C, it is the same question. It is just placed in a different order.
D) Search D corresponds with Venn diagram C, because it is what is in N and D or what is in N and C.

1) a)
“
new york state” and ( “death penalty or capital punishment”) 26 hits
b)
(“
new york state and “death penalty”) or “capital punishment” 371 hits
c)
“
new york state” and “death penalty” or “capital punishment” 371 hits
d)
(“
new york state” and “death penalty”) or (“
new york state” and “capital punishment”) 26 hits
2) a and d showed the same results . “ NYS” and “death penalty” or “capital punishment” means the exact same thing as “NYS” and “death penalty” or “NYS” and “capital punishment”. The first is just a simpler way to state it.
b and c had the same results. Whether using brackets or not these statements are the same.
3)
a) corresponds with the c) Venn diagram.
b) corresponds with the d) Venn diagram.
c) corresponds with the d) Venn diagram.
d) corresponds with the c) Venn diagram.
1)
a. Death and Penalty: 7102 hits
Death Penalty: 6563 hits
b. It always appears in the text and most of the time the words are adjacent but usually does not appear in the title.
c. put the whole phrase in quotations.
2)
a. d^p: 7102 hits
b. dVp: 150359 hits
c. s: 6563 hits
d. s^n: 637 hits
e. s^ ~n: 5186 hits
f. sVc: 7235 hits
g. s^c: 731 hits
3. And: to find documents containing two or more search terms
i.e: death and penalty finds documents mentioning death and penalty
Or: to find documents that contain any one of several search terms
i.e. death or penalty finds documents mentioning death, as well as documents mentioning penalty, or both.
Not: to exclude a search term
i.e. death and not penalty finds documents regarding death, removing those documents mentioning penalty.
4)
a. d^p: 15528 hits
dVp: 200415 hits
s: 4649 hits
s^n: 17 hits
s^ ~n: 4581 hits
sVc: 9132 hits
s^c: 5 hits
b.
d^p: 1659 hits
dVp: 22105 hits
s: 1633 hits
s^n: 0 hits
s^ ~n: 1630 hits
sVc: 3223 hits
s^c: 33 hits
1 -
A) DP = 936 D^P = 949
B) The words can be anywhere in the search together or apart which answers why there are more death and penaltys then the word death penalty together.
C) I would put the phrase in quotes….”Death Penalty”
3) And gives you results of both or however many items you search.
Not gives you the first word you enter and not another word thats you may enter ( joe not jack ) that might be widely associated with the other.
Or gives you the opportunity to put words in together to get the result for both of them or however many as appose to one or the other.
If you write an exact phrase like ” Music Television Movies” then those 3 words or however many, will need to show up together in the search and you will most likely get less results.
