    • [Science] - Free will could all be an illusion (Last post by Khaos)
    • Quote: But, we are all here on this big blue ball anyway, so what's the harm in speculating? Simply because there is no harm, does not mean it has any worth. Quote: And, maybe one of you smarty-pants will be inspired and figure out how to answer this, or some other currently questionable(?) question While I do not mind the appeal to my intellectual vanity, I am not so egotistical to think that I have the ability to figure something like this out. First and foremost because it doesnt matter.
    • The Grateful Thread (Last post by Edan)
    • I'm grateful that I got to spend the morning at a client's today... the office was quiet, the sun was shining through the windows, and I could hear the birds singing. Lovely.
    • Rants far and wide (Last post by Edan)
    • It's amazing the number of people I deal with everyday who seem to think I'm a mind reader. If I ask a question it's cos I need to know the answer... ignoring it completely or sending me something without explanation really isn't helpful and it just leads to me being annoyed I have to ask again, and them being annoyed when I do ask again. If they just read what I wrote the first time and responded appropriately we'd all be a lot happier...
    • Should jedi train in combat? (Last post by Bareus)
    • What i personally believe is that Jedi should be capable of defending someone and themselves, and in what way you want to do that is up to you. Personally i practice martial arts When we speak about "defending Jediism" then i see it so that we should verbally clear up misconceptions and misunderstandings that may give an individual a incorrect view of Jediism. Or correct any incorrect information given about Jediism that may mislead people
    • Graphene, "super material of the future"... (Last post by OB1Shinobi)
    • if anyone hasnt heard of this stuff, its awesome video: if youd rather read, from: www.graphenea.com/pages/graphene#.Vyt4W9IrIdU Spoiler: In simple terms, graphene, is a thin layer of pure carbon; it is a single, tightly packed layer of carbon atoms that are bonded together in a hexagonal honeycomb lattice. In more complex terms, it is an allotrope of carbon in the structure of a plane of sp2 bonded atoms with a molecule bond length of 0.142 nanometres. Layers of graphene stacked on top of each other form graphite, with an interplanar spacing of 0.335 nanometres. It is the thinnest compound known to man at one atom thick, the lightest material known (with 1 square meter coming in at around 0.77 milligrams), the strongest compound discovered (between 100-300 times stronger than steel and with a tensile stiffness of 150,000,000 psi), the best conductor of heat at room temperature (at (4.84±0.44) × 10^3 to (5.30±0.48) × 10^3 W·m−1·K−1) and also the best conductor of electricity known (studies have shown electron mobility at values of more than 15,000 cm2·V−1·s−1). Other notable properties of graphene are its unique levels of light absorption at πα ≈ 2.3% of white light, and its potential suitability for use in spin transport. Bearing this in mind, you might be surprised to know that carbon is the second most abundant mass within the human body and the fourth most abundant element in the universe (by mass), after hydrogen, helium and oxygen. This makes carbon the chemical basis for all known life on earth, so therefore graphene could well be an ecologically friendly, sustainable solution for an almost limitless number of applications. Since the discovery (or more accurately, the mechanical obtainment) of graphene, advancements within different scientific disciplines have exploded, with huge gains being made particularly in electronics and biotechnology already. The problem that prevented graphene from initially being available for developmental research in commercial uses was that the creation of high quality graphene was a very expensive and complex process (of chemical vapour disposition) that involved the use of toxic chemicals to grow graphene as a monolayer by exposing Platinum, Nickel or Titanium Carbide to ethylene or benzene at high temperatures. Also, it was previously impossible to grow graphene layers on a large scale using crystalline epitaxy on anything other than a metallic substrate. This severely limited its use in electronics as it was difficult, at that time, to separate graphene layers from its metallic substrate without damaging the graphene. However, studies in 2012 found that by analysing graphene’s interfacial adhesive energy, it is possible to effectually separate graphene from the metallic board on which it is grown, whilst also being able to reuse the board for future applications theoretically an infinite number of times, therefore reducing the toxic waste previously created by this process. Furthermore, the quality of the graphene that was separated by using this method was sufficiently high enough to create molecular electronic devices successfully. While this research is very highly regarded, the quality of the graphene produced will still be the limiting factor in technological applications. Once graphene can be produced on very thin pieces of metal or other arbitrary surfaces (of tens of nanometres thick) using chemical vapour disposition at low temperatures and then separated in a way that can control such impurities as ripples, doping levels and domain size whilst also controlling the number and relative crystallographic orientation of the graphene layers, then we will start to see graphene become more widely utilized as production techniques become more simplified and cost-effective. Being able to create supercapacitors out of graphene will possibly be the largest step in electronic engineering in a very long time. While the development of electronic components has been progressing at a very high rate over the last 20 years, power storage solutions such as batteries and capacitors have been the primary limiting factor due to size, power capacity and efficiency (most types of batteries are very inefficient, and capacitors are even less so). For example, with the development of currently available lithium-ion batteries, it is difficult to create a balance between energy density and power density; in this situation, it is essentially about compromising one for the other. In initial tests carried out, laser-scribed graphene (LSG) supercapacitors (with graphene being the most electronically conductive material known, at 1738 siemens per meter (compared to 100 SI/m for activated carbon)), were shown to offer power density comparable to that of high-power lithium-ion batteries that are in use today. Not only that, but also LSG supercapacitors are highly flexible, light, quick to charge, thin and as previously mentioned, comparably very inexpensive to produce. Graphene is also being used to boost not only the capacity and charge rate of batteries but also the longevity. Currently, while such materials as silicone are able to store large amounts of energy, that potential amount diminishes drastically on every charge or recharge. With graphene tin oxide being used as an anode in lithium ion batteries for example, batteries can be made to last much longer between charges (potential capacity has increased by a factor of 10), and with almost no reduction in storage capacity between charges, effectively making technology such as electronically powered vehicles a much more viable transport solution in the future. This means that batteries (or capacitors) can be developed to last much longer and at higher capacities than previously realised. Also, it means that electronic devices may be able to be charged within seconds, rather than minute or hours and have hugely improved longevity. Consumers can already purchase graphene-enhanced products to use at home. One company already produces and offers on the market conductive ink (first developed by researchers at the University of Cambridge in 2011). This is made by effectively mixing tiny graphene flakes with ink, enabling you to print electrodes directly onto paper. While this was previously possible by using organic semiconductive ink, the use of graphene flakes makes the printed material vastly more conductive and therefore more efficient. Another use for graphene along similar lines to those mentioned previously is that in paint. Graphene is highly inert and so can act as a corrosion barrier between oxygen and water diffusion. This could mean that future vehicles could be made to be corrosion resistant as graphene can be made to be grown onto any metal surface (given the right conditions). Due to its strength, graphene is also currently being developed as a potential replacement for Kevlar in protective clothing, and will eventually be seen in vehicle manufacture and possibly even used as a building material. As graphene has been proven to be much more efficient at conducting electrons than silicon, and is also able to transfer electrons at much faster speeds (relatively speaking, 1000 kilometres per second, 30 times faster than silicon), in the next few years you will begin to see products from consumer electronics companies, such as Samsung (who have been pouring money into researching the uses of graphene in telecommunications and electronics and have already taken out a huge number of patents concerned with the uses and manufacture of graphene in electronic devices) based on flexible, robust, touchscreen devices such as mobile smartphones and wrist watches. This could mean foldable televisions and telephones and eventually electronic flexible newspapers containing all of the publications you are interested in that can be updated via wireless data transfer. Being extremely translucent, in the coming years you can also expect to be able to fit intelligent (and extremely robust) windows to your home, with (potentially) virtual curtains or displaying projected images of your choice. Combining a few of these aforementioned potential uses, can you imagine car security systems that are connected to the paint on your vehicle? Not only would your car alarm be able to tell you if someone is touching your vehicle, it would be able to record that information and send it to you via your smartphone in real-time. It could also be used to analyse vehicle accidents to determine initial contact patches and resultant consequential energy dispersion. Soon we will begin to see clothing containing graphene-enhanced photovoltaic cells and supercapacitors, meaning that we will be able to charge our mobile telephones and tablet computers in a matter of minutes (potentially even seconds) whilst walking to school or work. We may possibly even see security-orientated clothing offering protection against unwanted contact with the use of electrical discharge. What all this means is that this discovery, made by a physics professor and his PhD student in a laboratory in Manchester, using a piece of graphite and some Scotch tape has completely revolutionised the way we look at potential limits of our abilities as scientists, engineers and inventors. The possibilities of what we can achieve with the materials and knowledge we have, have been blown wide open, and it is now conceivable to imagine such amazing prospective situations as lightning fast, yet super-small computers, invisibility cloaks, smart phones that last weeks between charges, and computers that we can fold up and carry in our pockets wherever we go. im at campus and i am finally done with finals, so i have a bunch of time to post right now i prefer not to link to wikipedia but i think this is ok its a(n impressive) list of potential uses en.wikipedia.org/wiki/Potential_applications_of_graphene i first heard of it from an article about body armor www.newscientist.com/article/dn26626-bul...-strong-body-armour/ or if you prefer: the highest caliber they use in this vid is a 45 but there is another from the same channel where they hit the graphene with an ak47
    • White Privilege (Last post by Goken)
    • Quote: EDIT i often post, and then as i read my post i either notice a mistake or i realize an idea that i forgot to mention, or that just belongs, and then i go and do an edit sometimes when i do this, i notice a "thank you" to the original post, which happened here, and i always wonder if the person feels tricked lol no trickery was intended! :laugh: I often have that fear. That's why I don't frequently edit my posts but rather make new ones. Since the "Thank you" was mine this time I can say I did not feel tricked. This time. :evil: :laugh:
    • A Childhood memory (Last post by Prelalo)
    • When I was younger there wasn't a day that I didn't get dirty, I was able test my limitations, what creek beds I could jump across, how fast I could run through a wooded area before I would run into a tree, how long I could hold my breath. I remember one occasion during physical education in school a fellow classmate had vomited, while the students and the gym teacher were waiting on the janitor I decided to get the broom and clean up the mess after a couple minutes of laughter and gross comments the most miraculous thing happened, one student grabbed the dustpan and another grabbed a trash can. That was the first time I was ever proud of myself and it was all because I just wanted to play with my fellow classmates.

    • My thoughts on this months reflection (Last post by MadHatter)
    • Ego Yet Humility This months reflection is ego yet humility. The first thing to do when reflecting on this to define the terms. Using the Merriam Webster dictionary we define ego as “ the opinion you have of yourself or self esteem” and humility is defined as “ the quality or state of not thinking you are better than other people : the quality or state of being humble”. Having defined these terms let us reflect on what the phrase means as a whole and how it applies to us as Jedi in particular. So looking at this phrase we can see that we can have ego but must temper it with humility. We can have high self esteem and a positive view of ourselves/our abilities without thinking that this makes us better as a person then other people. We can realize that we might be better AT something then others but that does not make us better then those without out talent. Its is a matter of balancing these two concepts so that one does not overwhelm the other. But why should we care if one over shines the other? Let us look at the dangers of this. If we have an over abundance of ego or in other words are egotistical we can try to take on more then we can chew and end up folding under the strain at the worst moments. Further it can lead to our discounting ideas and opinions from people we consider less then ourselves just because we are too proud to see the value of them. This forces us to learn the hard way. So what about the other side of the coin? What about having too much humility? What are the risks of that? If we are too humble then we might undervalue our thoughts, emotions, time, and well being. We might give too much of ourselves because we do not value our person enough to say no when we are over taxed. We might not speak up with a good idea because we don’t think its important enough. In short we might allow our own needs to be constantly put beneath others and risk becoming bitter and withdrawn. How does this apply to us particularly as Jedi? Well the entire code speaks to balance and lack of extremes be they good or bad. Too much of anything no matter how great it seems can be a bad thing. I personally love chocolate but too much is going to make you sick. So too can too much humility or ego poison the mind and spirit clouding perspective and making objective views next to impossible. Finally the most important reason to keep a balance is that we as Jedi are to recognize the sanctity of all life. So we cannot over value ourselves nor undervalue ourselves because all holds value in the connectivity of the living Force. Remember the true meat of a coin is not in the head nor in the tails but the metal between the two. So we see that the truly best perspectives are not in over abundance of ego nor humility but in a middle way between the two. To close let us look at a quote from the late Bruce Lee: “ Man should use his ego not be used by it or blinded by it”. This pretty much sums up how we should seek to view humility and ego. Tools to be used but dangerous if we are used by them.
