Want to know what your major should be, what you should do with your life, what cool jobs there are for you, or how to do a homework problem? This is the General Help sticky. Post those sorts of questions here, NOT IN A NEW POST.

Also, our IRC Trivia-SCI bot needs more Trivia. Especially looking for Mathematics and all fields of Science. No useless trivia, please. If you have any, post it here. Your post will be deleted once questions have been added to the bot. Stop in for a round! Link is at the top of this page, or just type the following line in your IRC client "/join #/sci/". Then type "!trivia". Please format your questions like this:

Up until a couple months ago, I had always thought that I sucked at physics, and had grades to corroborate. Then I found this book to the left: the Resnick/Halliday/Walker. All of a sudden things made sense in class and my grades shot up. Right now I'm lightyears of ahead of my class in physics. So my question textbooks does /sci/ reccomend for physics, chemistry and math?

This is now the textbook and and book request thread

I picked this up in the $5 bin at B&N years ago, Asimov's nonfiction is a great read for the layman.

Happy zeitgeist day slavefags

pic related, board chosen correctly. Project venus is about leading humanity through science, not violence and politics. Often i feel like im one of a rare few who understand the stupidity of governments etc.

Channers thoughts?

So basically you're saying that its the exact same bullshit and half facts that "zeitgeist" has been for years, and there's nothing new. Zeitgeist was mostly pseudoscience and conspiracy when it came out as a shitty movie that hoards of retards love and adore. What you've posted is certainly not new, and has no relevance to this board.

Scroll up and read the board rules.

Whenever you learn something, and then feel you have become enlightened above others, then you should slow down, release the excitement and consider it deeply. Consider whether you are correct or incorrect, consider whether you have actually been enlightened. It's very easy to become so satisfied with your new position that you don't bother analyzing things anymore. Sometimes, you have found some actual truth or understanding. Not most of the time though.

On the subject of this "zeitgeist" thing, there seems to be lots of fragments of sensible things, like "leading humanity through science", but it also seems to be wrapped up with a lot of nonsense. I would never buy an intellectual package deal such as this. It's the same reason I am not a Humanist. They take one sensible stance, Atheism, and then bundle in a bunch of stuff about ethics. Even if I agreed with the ethical stances, why attach them to the Atheistic stance?

Zeitgeist's drivel honestly sounds like old Soviet propaganda at points and at least the Soviets contributed.

Let's say, as a purely hypothetical mental exercise, you wanted to break into a bank vault or a high security safe. Without damaging the goodies inside, how would you get it open?

You're welcome to describe any method you can come up with, but try to keep it within the confines of the tools and skills you have, or could procure, at your disposal. So unless any of you own a tank, don't say you would just roll up in one and blow the hinges off with the cannon. You would probably destroy everything inside anyway...

Consider this for a moment. Intel's newest chips are using a 32 nanometer process, which means that the "wires" connecting the transistors together are roughly 32 nanometers long. The previous process was 45 nanometers, so we're jumping quite a bit every time.

The width of a silicon atom is roughly 1/4 of a nanometer, which means that the "wires" in the cpu are about 130 atoms wide, down from 180 in the last process. At this rate, it won't be long before it's physically not possible to make it any smaller. What then? Carbon nanotubes won't shrink it any (though they will improve performance drastically), so the only way to go is larger. What then? Will we eventually see dinner-plate-sized cpu's with 80lb heat sinks? Or will we stop growing the processing power and start shrinking the processes? Maybe both? What does /sci/ think?

Since there is no longer a Psychology board, I approach you, /sci/.

I am writing a paper on Kohlberg's stages of morality. Here I present you with a couple of scenarios. The answer you provide is not what I am interested in, it is the thought process involved in reaching your answer that I am after.

So please, if you have a second to look over these questions and shoot me a quick answer, I would be ecstatic!

1.) Two friends, Tim and Kyle, are walking down the street discussing Tim’s financial troubles. Tim has been laid off from work and doesn’t have enough money to provide food for his family. Kyle, on the other hand, has a job and some money saved up, though the ominous shadow of unemployment is always in the back of his mind. Tim asks Kyle for some money to pay for food and some bills. Kyle desperately wishes to help his friend, but knows in doing so he could possibly be putting his family in the same danger down the line. What should Kyle do? Why?

2.) Assume Kyle has refused to lend Tim the money. As they head off on their separate ways back home, Tim, with the knowledge that he scarcely has enough money to buy his family dinner tonight fresh on his mind, comes across a blind man collecting charity. The collection is for families that have been recently laid off and are in need of financial assistance. Tim, realizing that this money is for people in his exact situation, considers skipping over official channels and taking some of the money directly from the blind man, who will never know who is was that stole from him. What should Tim do? Why?

Thank you for your input, your help is greatly appreciated!

Ignore them, there is a bias against psychology as it is often believed to be the regurgitation of commonly held truisms. Psychology applies the scientific method to social and cognitive constructs. These construct are extremely complex, I would say the most complex constructs in human reality. However, it is difficult to control the wide range variability amongst people, the conditions, and even how material is presented, even when you use random assignment. Though it does not matter much, as our scales and measures are not very sensitive or refined; psychology is an infant science.

One also must account for the term psychology itself, more often than not, individuals who hold such a bias are thinking of clinical psychology alone. Clinical psychology has well been recognized for ignoring science and using unsupported methods to treat people. People also confuse psychiatry and clinical psychology. Ultimately, bodies of knowledge often suffer from elitist bias or are merely ignored. Who here really knows how large of an impact the ideas of psychologists like Skinner, Watson, Pavlov, Milgrim, Neisser, Hull and Tolman?

in question 1, kyle should think of long term planing. if he is already thinking it could be problematic for his family, he wont reach a conclusion that ends with him loaning the money

in question 2, it depends on Tim's state of mind; how long has he had these money problems, what is his outlook. The longer away both of those are from the present will increase his likeliness to steal, as he'll justify it by being desperate.

I've been wondering as to which came first, and since we know both are present I think we should also understand which came first. So, the question persists: soup or spark?

The question is meaningless -- soup doesn't create spark, and spark doesn't create soup.

B'sides, the "lightning in a swamp bottle" theory is *so* 19th century. These days we're finding polymer chains in cometary halos and deep inside meteorite rock. We'll probably find self-replicating polymers in the Oort cloud, where there's neither soup nor spark.

Why does the Rabies virus avoid most of the immune response?

How does it get through all those layers of immunity to result in 100% fatality!

It is THE god mode virus and it is absolutely incredible!

What do you think? Why?
>> No. 8169 ID: 8b7060
a lot of how the immune system works is chemical binding. maybe it doesn't have receptors to lymphocytes?
