As part of my introductory physics class next year I'm planning on including more history of science into the curriculum. During one class I've decided to include excerpts of translations from Galileo's Starry Messenger and Dialogues Concerning the Two Chief World System (I'll also include...

Hi, everybody :) I joined this forum because I'm currently writing a sci-fi story and I want to create an alien world that is scientifically correct, but due to my lack of knowledge and experience I'm facing some big troubles. I have a ton of questions(I hope I won't bother you much). So here is...

Hey! :o I want to begin with my master thesis and now I have to choose a topic. I am thinking about a topic that is related to theoretical computer science and more specific to Computability or to Complexity Theory. Could you give me some examples of topics that are related to Complexity Theory?

I am in my last year of high school here in my country and I've been thinking of something related to mathematics and physics and computers. I've decided that computer science would probably be the best course to choose. Do you know what is the best job you can get with a computer science...

Did Aristotle advance Western science? I know he was a geocentrist, but I'm looking at science before him, and there isn't much of anything there. The fact that he wrote down his ideas, in and of itself, seems to be an improvement in science. The fact that he was thinking, and talking, and...

I would very much appreciate if you could shed some of your insight on the following question that has been troubling me. I faced difficulty in computer programming as many times I could not find logic for even a simple problem (which many other classmates would do easily) while in some cases I...

Science fantasy vs science fiction. Do we have it wrong? At out science Meet Up group we were talking about Interstellar travel. As usual, the properties of matter, energy brought up. Regardless of how described in scientific jargon, FTL is all silly gobbledygook in science fiction books and...

Hi everyone. I am in my final year of an engineering degree, hoping through this site to find some much needed help with the science aspects of my final project. I look forward to discussing science!

Do you think Newton's piety was important to developing or fueling his philosophical and psychological impulses to be a great scientist and mathematician ? Did his religious and alchemical goals orient his scientific researches; his outstanding mechanical, mathematical, and optical theories...

Okay, so I'm currently sitting my final exams before I'll be attending university come September. Here in Ireland if you wish to attend any third level institute then you must apply to CAO (Central Applications Office) on your CAO application you put a numbered list of courses you are interested...

Can some name easy understanding book related to earthquakes, seismic analysis so that non civil engineer or geologist etc can understand can this topic and seismic analysis basics.

So, I've been inspired by shows like Fringe, games like Deus Ex and Halo, and movies like Robo Cop, The Machine, Eva, and Blade Runner. My interests would fall into the categories of things like neuroscience, biological engineering, nanotechnology, bionics, AI, body-computer interfaces, etc.--...

I'm familiar with the delayed choice experiment, and I'm trying to suss out this new setup. http://www.sciencealert.com/reality-doesn-t-exist-until-we-measure-it-quantum-experiment-confirms Reading this article is not very beneficial if there's a confounding typo. Paragraph 10: Should that...

Hi all again, I started a post earlier and it was buried somewhere by now. I really need more input and information and hope you all can help. How are admission process different, CM vs MS&E? CM belongs to Physics department while MS&E is usually on the engineering side. I got my Physics...

Hi all. Awhile back I posted about potentially changing schools to study Mechanical Engineering. Unfortunately financially this was not possible. However, my school does offer degrees in physics which I do find interesting. Currently I am studying Computer Science, and I'm considering adding a...

Hello, I will begin my junior year in MechE next fall. So far it's been an enjoyable degree and experience. the problem is, I tend to be more interested in the science itself of what I'm studying, rather than its applications. Which makes me sometimes think that I should have majored in a...

I am looking for a book on the history of science. I do not want one that is targeted to 'general public', in the sense that I want it to be more towards the academic community, i.e. more deeply presented and cited, etc. Are there any recommendations?

Hi PF, I have been currently pursuing a degree in Computer Science to hopefully end up having a career as a software engineer, as I am taking classes I am finding that the assignments are getting more and more difficult to a point where I find myself lost and in need of guidance. Which got me...

I'll be a 2nd year physics student next year, and my question is should I start taking some CS classes or take CDS (Computing for Scientists)? I've heard programming is very useful for someone trying to get into research or industry, but Computing for Scientists looks obviously useful as well...

Hellow guys, I know this topic is old for many people but I've read a lot of articles and forums and I would like to finally have a discussion started by me. So join me! I always enjoyed the universe and everything related to it, I am just very curious. As so I've seen a lot of Ted X videos...

An coworker's loves Charles Dickens and reads all sorts of other books with "high literary content". Most science fiction doesn't qualify as great literature. Lots of shallow character development, generally simplistic moral conflicts, etc. Mostly we have good stories in interesting...
