There are Linux gods, Microsoft gurus, famous scientists, notorious hackers, game designers, authors, entrepreneurs, and more. How many do you know? Go ahead and test yourself.<br /><br />For each name:<br /><br />1. <b>If you recognize the name give yourself 1 point.</b><br /><br />2. <b>Give yourself another point if you know an approximate date of birth.</b><br /><br />3. <b>Finally, a further 3 points for identifying what that person is famous for.</b><br /><br />Underneath the list is a set of links to help you find the answers. You'll have to do a little bit of research, but you wouldn't be doing a geeky test like this unless you enjoy that kind of thing... would you? :) * Update - I've removed some duplicates and marked those numbers with <i>DUPLICATE REMOVED</i>.<br /><br /><i><b>THE LIST</b></i><br /><br />1.

So I have prepared a list of questions\tasks that I think would be useful to complete before going for a C# related job. I have also provided a separate page with questions AND answers for the first set of 173 questions, and another page for the answers to the rest of the questions (not including Scott's questions). You can find the first link below the first set of questions and the second link at the bottom of the post - they are also directly below if you want to jump straight to them.</span></p><p><a href="http://www.toqc.com/entropy/TheAnswers1.html"><span style="font-size:78%;">http://www.toqc.com/entropy/TheAnswers1.html</span></a></p><p><a href="http://www.toqc.com/entropy/TheAnswers2.html"><span style="font-size:78%;">http://www.toqc.com/entropy/TheAnswers2.html</span></a></p><p><span style="font-size:100%;">Before you do the questions, make sure you follow these rules:</span></p><p><span style="font-size:100%;"><span style="color:#ff0000;">Rule 1</span> - Don't say to yourself "yeah I know that" and move on to the next question.

By saying a property is emergent we are saying that its parts cannot fully explain that property. It seems that, as though "by magic" these emergent properties appear when systems get complex, and large enough. The trouble is, even though they are real there is no overall classification system for them (like that of fundamental particles). So why not make one?<br /><br />Let's have a crack at it. first off we need a model and some rules.<br /><ul><li>Our model will be a universe made of a several instances of a single indivisible, fundamental particle, which we'll call <strong>A</strong>.</li><li>The concept of "size" in our universe will be governed by the amount of <strong>A</strong> particles we have. E.g. a size of 3 (<strong>AAA</strong>) is bigger than a size of 2 (<strong>AA</strong>). Emergent properties will happen at different sizes.</li><li>As with our (real) universe we don't really know what an emergent property is. There may be many more than we can percieve. So we'll assume that emergent properties happen with collections of <strong>A</strong><strong>.</strong> Our rule of collections will be simple, if we have a collection, <em>n</em> of <strong>A</strong> then the number of emergent properties of a certain size <em>x </em>is the number of times we can fit <em>x</em> into <em>n</em> (rounded down). NOTE - <em>this rule is arbitrary</em>.</li><li>Finally, we'll take it one step further and give each emergent property a name. Better still, we'll call it a new particle (e.g we'll say <strong>AA</strong> = <strong>B</strong>). Remember though, we only define these new particles by the number of <strong>A</strong> they contain, not by each other.</li></ul><p>Confused? Me too, here's an example:</p><p>First off, pure reductionism (no emergent properties). Let's count the number of particles in this system (we'll try it with a universe containing 5 <strong>A</strong>) <strong>. </strong></p><p><strong>1 AAAAA</strong></p><p><strong>2 AAAAA</strong></p><p><strong>3 AAAAA</strong></p><p><strong>4 AAAAA</strong></p><p><strong>5 AAAAA</strong></p><p>Size does NOT matter in this universe, if you used a microscope to peer down through the scales you would see at size <strong>1</strong> the 5 instances of <strong>A.</strong> As we get larger (<strong>2 and up</strong>) the 5 particles still totally describe the universe and nothing new happens (is emergent). No molecules with new properties, no vortexes, no human consciousness, etc. - just cold, hard, boring particles. The number of<span style="color:#ff0000;"> things</span> in this universe is 5.</p><p>Now let's add in some rules of emergence. </p><p><strong>1 AAAAA</strong></p><p><strong>2 (AA)(AA)A</strong></p><p><strong>3 (AAA)AA</strong></p><p><strong>4 (AAAA)A</strong></p><p><strong>5 (AAAAA)</strong></p><p>At size <strong>2 </strong>for example, size does matter - we have 2 new <strong>B</strong> particles (<strong>AA</strong>) and (<strong>AA</strong>). Following this logic further you can see we have an (<strong>AAA</strong>) particle, which could be called <strong>C. </strong>Then (<strong>AAAA</strong>) = <strong>D</strong> and (<strong>AAAAA</strong>) = <strong>E</strong>. When we replace sets of <strong>A</strong> with other letters we get:</p><p><strong>1 AAAAA</strong></p><p><strong>2 BBA</strong></p><p><strong>3 CAA</strong></p><p><strong>4 DA</strong></p><p><strong>5 E</strong></p><p><br />The list of all <span style="color:#ff0000;">things</span> here is (A,A,A,A,A,B,B,C,D,E) which is 10 entities. The number of <span style="color:#ff0000;">things</span> can be counted by using a basic formula:</p><p># of <span style="color:#ff0000;">things</span> = sum[i=1,...,n] (floor(n/i))</p><p>So we can loosely say that 2<strong>A</strong> = 3 <span style="color:#ff0000;">things</span> (an <strong>A</strong>, another <strong>A</strong>, and a <strong>B</strong>) so, roughly speaking, 1+1=3.</p><p><strong><em>So what's this good for?</em></strong></p><p>The classification and categorisation of emergent properties is adhoc. What if there is a pattern in the REAL WORLD by which we can classify and possibly even predict emergent properties?</p><p>Something to think about...</p><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/10153993-110778590919951289?l=rileyperry.blogspot.com' alt='' /></div>Riley T.
