  1. i just thought of something else, the formula of einstein, E=mc^2E = the amount of energy you need to give a object with the weight of m (in kilo's) the speed of light ©.c = 300.000.000c x c = 90.000.000.000.000.000 metres/secondlets say i want to give an object that weighs 1 gram the speed of light,according to the formula that would be 90.000.000.000.000 JoulesThe nuclear bomb dropped on Nagasaki during the 2nd world war had the energy of 84.000.000.000.000 Joules.See how difficult it gets, AND, keep in mind how much damage the bomb did to that place. And how are you going to make sure that all the energy is transferred to the 1 gram object and it's almost impossible to create a barrel that will hold such blast.


  2. Still, a object can't be given the speed of light because there wasn't enough energy (oil, gass, stuff) in the entire universe, (proven by some scientist ). AND, how can you say that something operates at the speed of light? the speed of an object is metre/second, that's different from computer speed, cpu-ticks/second that simply can't be compared. to keep it simple.the speed of an object is different from the speed of operation. people often get confused in that.


  3. easy cake. here's the code (just made it up should work)html -- [feedback.html]===============<html><head><title>asdf</title></head><body><form action="feedback.php" method="post"><input type="text" id="name" name="name"> <--- the senders name<input type="text" id="email" name="email"> <--- the senders mail<textarea name="contents"></textarea> <--- the mail contents</form>=======================================end of html file now start PHP file=========feedback.php =========<?php$_POST["name"];$_POST["email"];$_POST["contents"];mail('youremailadress@foobar.com', 'Feedback mail', 'mail sent by' . $name . ' with email adress ' . $email . 'contents : ' . $contents);?>


  4. There's no reason to BUY any html page editor thingy, dreamweaver is just like frontpage but a little better. But on the long run, text-editor-webmasters will excel over the GUI-web's because GUI is limited in functions. I could do a few things with tables in VIM / notepad that you can't do in dreamweaver or frontpage.BUT, GUI-interfaces are indeed usefull if you just start learning html.


  5. IP is easy if you mean the client that connects to your server has to be logged.$adress = $_SERVER['REMOTE_ADDR'];insert that line and the variable $adress will be the IP you need.But city is not possible i think, because the IP only refers to the company that has registered the subnet ( first 3 digits of you ip). So you can only find out who someones ISP is. And in wich country someone is. All you need to do is a whois to the ip you just got.


  6. My physics teacher also told me that if you move very fast, let's say you're moving in a very fast train, the clock on that train would tick slower than the clock on the train station (you would be going forward in time). So, if you move at the speed of light, you would be going a lot forward in time. But he also said that it's impossible to give something the speed of light, because there isn't enough energy available in the whole universe.


  7. It's unethical, but it's the industry's own fault. They're charging way to much for stuff that's produced for a small fraction of the price you pay. AND, if it weren't for illegal downloads, noone would consider using highspeed internet, hell, if you just browse and mail, why would you use highspeed.
