sceince questions

One of the greatest scientific developments of the past 150 years is the discovery of antibiotics. For some basic background on antibiotics, listen to this very brief Centers for Disease Control (CDC) podcast about antibiotics:  

There is, however, a dirty little secret about Alexander Fleming and his discovery: it was an accident! As Fleming worked in his lab in the late 1920s growing disease-causing bacteria in tiny petri dishes, he got a little sloppy by leaving the petri dishes uncovered too long. One story even suggests that he may have sneezed into one of his petri dishes. Regardless of the exact cause, what resulted was a mold infestation on some of his bacterial dishes. However messy Fleming was, he was also smart enough to see that the mold infestation was killing off the bacteria he was studying. Completely by accident, he had found something that killed disease-causing organisms.

Such “happy accidents” are not uncommon in science. Some notable examples include aspartame (NutraSweet) which was discovered by a drug chemist who forgot to wash his hands. Even Isaac Newton benefited from a little accidental inspiration when he (supposedly) came up with a description of the concept of gravity after being knocked on the head by a falling apple. Scientists, like everyone else, make mistakes but, the best scientists use their mistakes and learn from them.

Reflect about the famous Louis Pasteur quote: “Chance favors the prepared mind,” as well as what you learned about scientific inquiry throughout the course. Then, during the week, address the following:

  1. What examples of learning by “happy accident” have you experienced in your own life?

What do you think it means for a person (especially a scientist) to have a “prepared mind,” as Pasteur describes?


How can a person prepare his or her mind to be open to chance within any particular discipline? What roles might education, job experience, and life experience play in creating a prepared mind?


What about science makes it particularly good at allowing people to analyze their accidents?


What are some risks associated with research that involves chance consider the risks associated with stem cell research, cloning, gene therapy, HIV.] Are there circumstances when research should not be conducted due to risks or are there ways to reduce risk?

Programming in C# console application

Major Assignment


This assignment will provide practice and experience in:

·         Writing a program – Topic 2

·         Debugging– Topic 3

·         Stepwise Refinement& Modularisation – Topic 4 and Topic 10

·         Selection – Topic 5

·         Iteration – Topic 6

·         Arrays – Topic 7

·         File handling – Topic 9

·         Structs – Topic 11

NB Depending on when you start this assignment you may need to read ahead especially on how to use files andstructs.


Read the assignment specifications carefully first.Write the first version of your program in Week 4 and then create new versions as you learn new topics. Do NOT leave it until Week 11 to start writing the program. Review Topic 4 on stepwise refinement. This is how you should approach the major. Also note that though your program must do something and must compile it does not have to be complete to earn marks.


One of the many tasks that programmers get asked to do is to convert data from one form to another. Frequently data is presented to users in well-labelled, tabular form for easy reading. However, it is impossible or very difficult to do further processing of the data unless it is changed into a more useful form.

For the purposes of this assignment I have downloaded and will make available the undergraduate applications to the 37 Australian universities from the Department of Education for 2009 – 2013 data file as a text file.

Your program will load this data into an array of structs, save the data in a form that is directly usable by a database (see below), display the data on the console in its original form and in its database form. It will also allow the user to display the highest number of applications for a given state and year.

Your program will use a menu to allow the user to choose what task is to be done. You will only be required to handle the Applications data. You can ignore the Offers and Offers rates data (see below).


See “undergraduateapplicationsoffersandacceptances2013appendices.txt” for the original data.

This is the data your program should produce and save:

Suggested Approach (Save a new version after each step)

I have put in brackets my assessment of the relative difficulty of each task. I found a hard task took more effort than a medium task which in turn took more effort than an ‘easy’ task.

1)      (easy) Write a method to display instructions to the user

2)      (easy) Write the code to display a menu and test it

3)      (easy) Write the code to display the contents of the data file line by line

4)      (easy) Write the code to save the contents of the data file to a new file

5)      (medium) Write the code to copy the file data into a simple array of structs where the structure is something like:
struct data  string line;
and the array is
data[] myData = new data[100];

6)      (easy) Write the code to deal with the unnecessary data at the start

7)      (medium) Write the code to deal with the unnecessary data at the end

8)      (hard) Write the code to modify the code to convert the original data into database format. You do not have to follow the exact structure given above, e.g. you could use commas instead of tabs

a.       You may want to divide this into two problems. First treat the numbers as a string, i.e.
New South Wales, Charles Sturt University,”3,769″
and when you have that working then work out how to convert “3,769” into 3769 etc

9)      (easy) Modify the struct to handle the modified data

10)   (easy) Modify the file save code so that is saves the modified data

11)   (medium) Write the code to find the highest number of applications in a year for a state


NB you can simulate any step in order to gain marks. For instance if you cannot modify the data into database format you could have a separate file with the sample data abaove and use that data to show that you can find the highest value in an array of structs.


You must zip (zip not rar, arg, hqx, 7z or any other format) your entire project, include the marking sheet with the Assignment Cover Sheet section completed and upload the one submission.


Failure to follow these instructions will delay marking and you may be asked to resubmit the assignment correctly.


A couple of Articles are attached.

I can format paper, only need contents.
