I had a discussion with someone who studies psychology recently and she was referring to mental stress as of what I thought being called physical stress. Namely while she was talking about mental stress she mentioned stressors and hormones. So my problem: Stress = tension Physical =...

Hubs don't exist anymore since switches are so cheap to make. So below you can see the main differences: Switch Works with MAC addresses Connects computers in a LAN (Ethernet) Router Works with IP addresses Connects computers in a WAN (Internet). An other way to put it: connects different...

I am trying to learn about neuroscience on my own but every book I have picked up goes so much into details for every single thing that I tend to miss the bigger picture. I have some questions that I can't seem to find answers on, mainly about how neurons work. Keep in mind that I have a...

Thank you for your reply. I read it also on my previous thread but couldn't answer because the thread got closed. Portfolio is pretty much a way to show your work. In this case as a coder and designer, I try to show some of my coding projects and some of my graphics. I agree, "wanna" is a...

I opened this thread under General Discussion but it got closed without me knowing why. So I repost it here(assuming that it was in the wrong place). So I am a soon under-graduate in computer science and I've put up a portfolio to stick out from other candidates when I apply for internships...

Although I have taken Discrete Mathematics I am really bad with probability and would appreciate your insight in this. I had a discussion with a friend about aliens. So the question that arose is what is the probability that aliens on a different planet somewhere look similar to an animal...

I will be honest and say that one reason I prefer other similar web sites to physicsforums is the looks of it. I think physicsforums has the best people to discuss with but the previous appearance of the forum was really ugly. The new design looks better but it could become even better. I...

Ok, but if each parent has 2 alleles, then we have a total of 4. How are only two alleles chosen from those 4 for the child? Is it a random choice?

I am learning about genes and heritage currently and I am a bit baffled about something. In my book it states that in a plant's gene, if S is for smooth leaves and s for rough leaves, then we get these combinations: Parent plant | Child plant | Dominant alleles S + s -> Ss...

Free courseware is good but I already spend a lot of my time in front of the computer so would prefer something I can read when I am in the toilet or on the couch. The two books mentioned look good but not cheap. I have started considering maybe buying an ebook reader instead and just...

Hi, I have been looking through amazon all night reading reviews and I am baffled about which book I need :confused: I study Computer Science at bachelor level and recently got an interest into biology(not sure which kind). I want to be able to read an article or a forum's post on for example...

I am 25 years old and I have completed 2 years of bachelor courses where the majority is courses in Computer Science. Now I find myself in a situation where I can take specific courses for the 1 remaining year and get a general bachelor degree. With this general bachelor degree I am able to...

I am not sure myself. We just started deeper into Java at my class at the moment and it feels like it's not my thing.. I want to know exactly what I am doing. With all the abstraction I feel like this is a philosophy class and not a technical class. That's the main thing that got me into...

I have taken Computer Science for a bit more than a year and I was concidering to maybe jump to Electronics. My main reason for this is that I don't want to spend the rest of my life on a chair. I do love sitting by the computer, scripting/programming, learning and everything but I feel that...

Sorry for being mystical. I will clarify: random binary matrix of size 4: 1 0 1 1 0 0 0 1 1 0 1 0 0 1 0 0 random binary matrix of size 2: 1 1 0 0 and so on. So i make random such binary matrices M from size 1 to N. I also make a binary vector b in the same way. Then I try to solve them...
