/sci/ - Science & Math

Hey guys im 18 and currently going for Business Administartion. I doing great my GPA is 3.84 but i want to do more. Lately i got interested in computer science( im not good in computer tho) and i think i may change my major. Currently im talking an free online Cs101 and it looks nice!
Tell me the pros and cons of it!

What is the science in Computer Science?

Is CS or ECSE a meme? I'm currently a ChemE but nearly shit myself when I just saw some of these guys' starting salaries, benefits and hours in greater NYC of California. Is it worth switching over or is there something I'm missing?

I had a date with a 19-year-old today. I'm 24. Her profile seemed normal, but on the date she eventually said that she was stupid using the politically correct term "learning disabled." She didn't even really admit to having one, but she said she had one as a kid, which is the same shit. As soon as she said that I pretended to be interested for another 10 minutes and left. This is the second time this has happened to me this year. Previously, it was an 18-year-old woman who said the same shit, at the same coffee shop over the summer. Both of them were over 17 and not in university/college, but working. It used to be that there were some normal people who would forgo college to do other stuff, or take a gap year/holiday, but it seems like every single fucking person goes to college now, unless they are some kind of retard. I can't find the stats right now, but I remember reading that something like 60% of Canadian Gen Y women have gone to university or college, so at least 20% of below average intelligence women go to college. I never called the first one back and I'm not calling the one I met today either.

Is college basically high school now? Is it really so worthless that only the most retarded people don't go to it. I used to think of college or university as a personal choice that was right for some people and wrong for others, but it's basically just part of high school that you have to pay for with your own money or your parents' money now. It's been completely ruined by this. Even STEM is being inflated. It makes me wonder what my degree is going to be worth.

If you live in a first world country, don't bother with women who haven't gone to university even if they're under 20. 2/3 times they are stupid as hell. College is the new high school.

I'm a CS student. In the beginning of the course, there wasn't much math, some teacher said that in practice they don't use math at all. Some said that in some specific areas like AI, more math was used. Great, I wanted to study AI anyway. So finally I began to study AI and was one of the biggest disappointments in my life. Some fields like metaheuristics have no cohesive theory at all. Worst: I almost don't see people putting effort to find one. No elegant universal analysis or mechanism. Very little math used. Most publications are in the style of "I tried to change the parameters of this algorithm to this to see if it works better in some random instances of this problem".
But I believe that CS is important. In particular, I believe that AI is important.
You guys adore to mock CS. Fine enough. But can you suggest what math would be necessary to study CS and AI "seriously"?
I'm asking this probably because of how much I'm disappointed with my field, but still, the question is serious.
I would specially welcome answers from mathematicians that turned to the field of AI.
Most of the more relevant theorems and theories and algorithms that I saw in CS and AI were actually made by mathematicians and physicists, now I’m not surprised.

im confused about the differences

or is it a way to justify computer science as a field?

Reminder that CS is a subset of Cryptozoology

My program to find the primes up to the number you enter works like this:

-Creates array half the size of n that will hold the primes
-Sets the first element as 2.
-Starting at 3 (call this "place") and moving up the odd numbers until n or greater, it divides each of those numbers by the previously found primes, until the prime is equal or greater to half of place, and if none divided evenly, it adds place to the prime array.
-After place is greater than n, it exits the outer loop and if the last place was prime and place is 2 greater than n, then n is prime.
-Now I not only have determined if n is prime, but I have an array of all the primes up to n, which I then display for the user and tell them how many of them there are.

How can I further improve the efficiency of this program? Right now it finds the first 30 primes in only 326 comparisons of the inner for loop, and 100 primes in 3382 comparisons.

I'm majoring in computer science and I've hit a brick wall with 10 credit hours due to pre-reqs so I would like to pick a bs class to keep myself busy. Which would be a better choice? Intro to Homeland Security or Intro to Terrorism? Serial Killers course is already filled and intro to cyber-terrorism was canceled.

CS majors why do you waste 4 years and thousands of $ doing something you could literally learn for free?

/sci/ is this the ultimate meme STEM field?

What actually is computer science?

15 days to start computer science class, how hard is it? I was kinda good at math in high school and I enjoy programming.

import java.util.*;
import java.io.*;
public class Dictionary {

//fields
private Map<String, List<String>> myData;

//constructor
public Dictionary()
{
myData = new TreeMap<String, List<String>>();
}


//methods
int addDefinition(String word, String definition)
{
if (!myData.containsKey(word))
{
myData.put(word, new ArrayList<String>());
}


myData.get(word).add(definition);

return myData.get(word).size();

}

String removeDefinition(String word, int index)
{
return word;

}

List<String> removeWord(String word)
{
return null;

}

List<String> wordlist()
{
return null;

}

List<String> wordlist(String letter)
{
return null;

}

List<String> lookup(String word)
{
return myData.get(word);

}

boolean contains(String word)
{
return false;

}

int size()
{
return myData.size();


}

int load(String filename)
{
return 0;

}

void save(String filename)
{

}

void printword(String word)
{

}

void printAlpha(String letter)
{

}

void printAll()
{

}
}

proti:

new kind of science = computer science
