Is it possible to have it shipped to the U.S.? I checked it out once I heard about the offer, but did not see shipping options for outside of the local area.

Video A great production from BBC. I had not seen this before so I figured I would post it for others that had not seen it. After I watched this, I downloaded the entire show and was very pleased with the quality, both in content and production value. It was refreshing to see quality graphic work put into an evolution video. **I posted this here so as to make it visible to everybody rather than sticking it in biology as it's more light-weight than I would expect for that forum. Feel free (as I know you would) to move it if deemed necessary.

I'm a math student and would like som feedback
Scientia replied to khelben1979's topic in Mathematics
One thing that I notice from a cursory view is that your solutions are written like fractions. I kept wondering why you were ending up with rational expressions until I noticed the pattern. -
Quickly identifying upper and lower bounds for zeros
Scientia replied to Scientia's topic in Linear Algebra and Group Theory
Thank you for your response. I'll be looking into Sturm's theorem, although it's probably way over my head at this point. I've pretty much just been doing what you mentioned. I just look at a specific term and estimate about what I need to change my divisor to in order to make it positive or negative. I was just wondering if there was something that I missed. I suppose that i'll just have to get used to the idea that not everything is perfectly clear, especially as I progress into more advanced mathematics. -
I have a quick question regarding the identification of the lowest upper bound and the greatest lower bound for the zeros of a polynomial function. The method that my book shows is to use to upper and lower bound theorem involving synthetic division. This involves performing division with 1, 2, 3, etc. and -1, -2, -3 etc. until the bounds are found, but what if the lowest upper bound is something like 57 or 89? I'm I supposed to perform division for every number or is there a way to identify a smaller group of possible bounds. I've just been using the results of division to estimate about where it would be and eliminated possibilities from there, it just does not seem very...I don't know.. math-like to have to do that.

I seem to be having an inordinate amount of difficult with understanding the concept of horizontal stretching and compressing graphs. Vertical stretching and compressing makes sense. [math]y=2f(x^2)[/math] If I understand it, this is simply multiplying the output of the function by two. All that happens is that the [math]y[/math] value is double whatever it would be as a result of [math]y=f(x^2)[/math]. This means that an input of 1 gives a [math]y[/math] value of 2, an input of 2 gives 8. This would stretch the graph away from the x-axis due to the y value increasing faster than it otherwise would. The part that confuses me is when you multiply the [math]x[/math] value while it's inside of the function. I was unable to figure out how to graph Horizontal stretching on a calculator so I just manipulated the functions to show the graph that I wanted for this post. Below is the graph of [math]y=f(x^2)[/math]. This is simple enough, what confuses me is what happens when I give [math]x[/math] a coefficient greater than 1. [math]y=f(2x^2)[/math] Now I realize that to graph this, all that I have to do is multiply the [math]x[/math] coordinate by [math]1/2[/math] and keep the [math]y[/math] coordinate the same. [math](1,1)[/math] becomes [math](.5,1)[/math] and [math](2,4)[/math] becomes [math](1,4)[/math] etc. The problem is, I don't understand why this happens? Why am I not doubling the [math]x^2[/math] like I intuitively would? EDIT: I think I may have discovered what part of my problem is, [math]y=f(x^2)[/math] does not result in the graph that I have posted above as the function referenced by [math]f(x^2)[/math] is not given. I think what the book is asking is, what value of [math]x[/math], when multiplied by 2, gives the same output as the function would have if not multiplied by two. Is this correct? If so, it would explain what is happening as a function [math]f(x) = x^2[/math] (the actual function for the first graph) would indeed result in the value of [math]x[/math] needing to be .5 as [math]y=f(2x)[/math] when [math]f(2x)[/math] would be referring to [math]f(x) = x^2[/math]. .5 would be multiplied by 2 and then passed to the function which would square it to give the value of 1. Making the coordinates [math](.5,1)[/math].

I'm not a physicist (yet) but I would say that being open minded in any scientific field would mean that you do not dismiss theories that you do not agree with without objectively examining the evidence.
-
Just thought that I would let you know that you are awesome. The quality of your posts are very high (where applicable) and played a very large role in my decision to begin visiting the forum daily. Since I joined a couple of months ago, you, along with some of the other advanced members, have astounded me with your grasp of your fields of study (although I am hardly qualified to rate your expertise) and renewed my outlook on the value of online communities for the discussion of science. I grant you one 'woot', do with it as you please.
Mildly relevant information: I'm a physics major, which has made you particularly appealing....academically that is...<_<.

Go to a local community college for a remedial math course. This will start from a very basic level and move up to pre-algebra. Don't be afraid to ask questions in class. Aside from that, without having an instructor, you will find any type of auto-didactic methods frustrating.

That was indeed a wonderful talk. Dawkins never fails to deliver.

Religion is attacked because of it's demand to be believed as correct. (Varies with different religions.) A preference of pepperoni over sausage does not mean that the sausage eaters are wrong, it's accepted as an opinion. Many religions on the other hand declare themselves to be true and all others to be false. They may even go as far as to damn those who chose another belief to spend eternity in hell, or reincarnate as a lesser being or object. Now, depending on how far the religion takes this, it can become a burden on others which is evident through war and crime done in the name of any particular religion. There are many other reasons why religion is such a strong focus of dialectic such as it's claims on the origin of life and the universe. These are questions which we hope to one day answer through science. Many religions attempt to answer these but can not provide the evidence which a scientific approach requires. I recognize this as a difference between science and religion/faith however in a society where scientific amelioration has played a large role, it seems that more people are becoming dissatisfied with the reports given by some religions. I could digress further and take up more of your time however I will attempt to end this post quickly. Science and religion do not easily get along, it comes down to science's role in society and religion's. As science begins to replace religion's accounts with it's own, the debates will only grow in number and ferocity. While I feel that religion could be eradicated or at least demoted to mythology and we would be better off, my lack of experiment/studies do not lend me the authority to make that claim officially with any real credence. ^--$0.02

From the video it looks like he jumped or at least began to jump as the car hit the crates. This would make his movement completely separate from the crates, the only risk would be the possibility of him falling off early and being run over or having a crate hit the windshield and come back up at him. If he had stood on the crates the whole time he would have likely been just fine anyway. I'm not a physicist (yet) but if I had to guess I would say that his inertia (or resistance to a change in his state of motion) would keep him from moving anywhere but down due to gravity. The car would likely be well out of the way by then.

I'm pretty sure my focus with switch to C soon. I program in Python currently as a hobby.

Why don't you read the file contents into a list?

Try using a diagnostic boot cd like Hirens (link at bottom of message). It could be that all of that rattling has damaged one or more of your hard drives. Use the boot CD to run tests on the hard drives. Run read/write and surface checks. You could also try the recovery console and run chkdsk.

NOTE: This is an early program, the code is messy, uncommented, and could probably be shortened considerably with a skilled eye. I however have lost most of my interest in updating the program, if I was going to do it again it would be a complete re-write. I'm far too busy to do that now. This was written as a way to reinforce programming techniques that I was learning and to waste a boring day. It works as far as I know, if anybody wants to add/remove/edit the program, have fun. Save your criticisms for somebody who cares. Pyspoof 2.0 ------------------------------ A pseudo-anonymous email spoofer with address collecting. What is it? =+=+=+= Pysp00f started off as a very simple email spoofer written in Python, essentially that's what it still is. It's written in Python so you'll need to have Python installed on your system to run it. You must be warned though,if you don't use an anonymous smtp server you can be traced. Most people wont even get into that unless you try something really stupid such as bomb threats or any other similar bad idea. Features =+=+=+ A) Can send a single spoofed email. B) Can read in addresses from a text file and send the same email to all of them. C) Can take a URL from the user and pull just about every email address off of the page. D) Can take a text file from the user and find and pull out just about every email address. E) Can check old and new lists for duplicate entries. A) Single Email =+=+=+=+=+ If you select this from the menu, you'll be prompted for a 'From' address, this is the address that will show up to the receiver of this email as the sender. That's the 'spoofing' part of this program. It will ask for the address of the receiver, then a subject, then it will prompt for the body. Enter the body, press enter twice when you finish. Once you do, it will ask you for an SMTP server, if you don't know one use Google, or contact your ISP and ask for theirs. Next, just press enter and it will send the email to the specified address. B) Mass Email =+=+=+=+=+ If you select this from the menu, you'll be prompted for a list of email addresses, this list should be formatted as one address per line and needs to be in the same directory as this program. Give it the file name including the extension (.txt) and it will load the addresses. It will let you know how many it's loaded and ask you for the receiver, the sender address, subject, body, and server just like the single email function. Fill these out and it will send the email to all of the address in the file, it will notify you every time it attempts to send a message, and every time it successfully sends a message. It has a 10 email limit, once it reaches this, it will disconnect from the server, pause for 12 seconds, then reconnect and keep going. Some servers will limit the amount of emails you can send per session. Usually 10 is low enough to keep from having any troubles, if not then change it in the source. C) Web page scan =+=+=+=+=+=+ By selecting this option in the menu, you'll be prompted with another two options, to scan a web page or a file. In this case we'll discuss a web page. Select the option 'a' and it will prompt you for a URL. Enter the full URL of the page you want it to scan, once you do this it will connect to the server and grab the page. It will then ask you for a domain to scan for, this would be @hotmail.com, or @yahoo.com. If you want it to scan for everything that looks like an email address, simply enter an asterisk * instead of a domain. It will scan through the page for email addresses and let you know when it's finished how many its found. It will then prompt you for a filename including the extension that it will save these to, good thing about this is that it saves them in the proper format for the mass mailer. If the file you specify already exists, it will append the addresses to it. In the latest update, it now checks the file for duplicate entries, removes them and updates the file with only unique addresses. It's a good idea to look over the email address list before you use it. This is handy when you want to grab a bunch of emails from a site and send them all a message and be pseudo-anonymous in under a minute. Usually something that can take quite a long time. D) File Address Scan =+=+=+=+=+=+=+ This is very similar to the URL scan except in this case it scans a file. This is useful for when you've either got a bunch of email addresses in a file and want them to be formatted for the mass email function, or you've got something like an html file with addresses hidden away in the source. As with the URL scan, it will scan for addresses either with a specified domain or if you use the * option, it will scan for anything that looks like an address. As I said before, it's a good idea to look over the list before you use it for false addresses. It will notify you of how many addresses it found just after the scan so you can be sure early on of how many addresses you'll have. Just like in the URL scan, it will perform a duplicate scan over the file and let you know how many duplicates it found and removed leaving you with a file full of unique addresses. E) Duplicate Scan =+=+=+=+=+=+ This will allow you to enter a file name for it to scan for duplicates, it will scan the file line by line to see if it contains the same address twice, if it does, it will remove it. After it finds all of the duplicates it will tell you how many it's found and then overwrite the old file with a new list containing only unique addresses. Make sure you've got it formatted as one address per line, if you don't feel like doing it yourself, just run a file address scan (see D) and it'll format it for you. If you don't set it up this way, it wont work. F) Command Line Arguments =+=+=+=+=+=+=+=+=+=+ In the latest update, I have added support for command line options. This is useful if you want to run it while you're not home or away from the computer, every option can now be set automatically in a script and fully automated. When using a script to send emails, mass or single, you must have the body in a text file in the same directory. When specifying the subject, use underscores for spaces.

Not that I can contribute this, but I thought that it would be interesting to see the home/work labs that some of the people here use. It would help to see what other people in your field use and give you and idea of what you could use.

eztvefnet.org has full episode great quality downloads. It's great for shows.

@Innit: You say that you're currently a student at school. Would this be high school or college. If it's college, what is your major? What are your current classes focusing on? What is your mathematical knowledge?

@bignose: I really enjoy Numb3rs, i've got every episode to date on an external hard drive. I've also just watched the first 4 episodes of Big Bang Theory. I agree with your statement, it's simply okay. Strange thing, in the first episode, the first bit of dialogue between the two main characters is a discussion about the double slit experiment. The tall one (names escape me) is explaining the main result to the shorter one as though he has never heard about it. I do find it hard to believe that one can achieve a doctorate in physics without knowing of the experiment. @uncool: Part of the show's appeal to the general public is the over use of such jargon by complicating the scenario. It makes the mathematics seem more abstruse thereby inducing awe towards Charlie's intelligence. This is seen in many shows. A good example of total negligence towards realism is Live free or Die Hard. The computer 'hacking' was absolutely ridiculous and even a bit insulting towards the lack of knowledge on the subject of computers held by most. Did anybody notice that they used three of the actors from the show Rosanne? Strange to see them working together again. Edit: Futurama is a fantastic show, the quantum finish was quite funny. Here is a link to some interesting mathematical and scientific occurrences from the show's series so far. Number 15 is the quantum finish... http://usuarios.lycos.es/bbrp/mathematics.html

That's something that I just don't understand. For shows that focus on the medical field such as House, they don't think twice about using real medical jargon in the right context. It seems that whenever anybody gets near a computer on a television show, they quickly execute some unrealistic task with a few keystrokes, barely ever do they use a mouse, and everything is animated with annoying sound effects. More shows need to embrace science and technology and have experts in the fields working with the writers to respectfully include the material into the script.

This was read on The Screen Savers a while back. It's a joke, as has been stated multiple times in the thread. It's also been passed around the internet for many years now. The real worry here is that some parents really feel like this.
