      doesn't go with the divisions of the knowledge map
    • Erin Hamson
       
      and then this other paragraph begins the division
  • If one reflects somewhat upon the connection that discoveries have with one another, it is readily apparent that the sciences and the arts are mutually supporting, and that consequently there is a chain that binds them together. But, if it is often difficult to reduce each particular science or art to a small number of rules or general notions, it is no less difficult to encompass the infinitely varied branches of human knowledge in a truly unified system
  • We can divide all our knowledge into direct and reflective knowledge. We receive direct knowledge immediately, without any operation of our will; it is the knowledge which finds all the doors of our souls open, so to speak, and enters without resistance and without effort. The mind acquires reflective knowledge by making use of direct knowledge, unifying and combining it.

  • Let us sto
  • p here a moment and glance over the journey we have just made. We will note two limits within which almost all of the certain knowledge that is accorded to our natural intelligence is concentrated, so to speak. [34] One of those limits, our point of departure, is the idea of ourselves, which leads to that of the Omnipotent Being, and of our principal duties. The other is that part of mathematics whose object is the general properties of bodies, of extension and magnitude. Between these two boundaries is an immense gap where the Supreme Intelligence seems to have tried to tantalize the human curiosity, as much by the innumerable clouds it has spread there as by the rays of light that seem to break out at intervals to attract us. One can compare the universe to certain works of a sublime obscurity whose authors occasionally bend down within reach of their reader, seeking to persuade him that he understands nearly all. We are indeed fortunate if we do not lose the true route when we enter this labyrinth! Otherwise the flashes of light which should direct us along the way would often serve only to lead us further from it. The limited quantity of certain knowledge upon which we can rely, relegated (if one can express oneself this way) to the two extremities of space to which we refer, is far indeed from being sufficient to satisfy all our needs. The nature of man, the study of which is so necessary and so highly recommended by Socrates, is an impenetrable mystery for man himself when he is enlightened by reason alone; and the greatest geniuses, after considerable reflection upon this most important matter, too often succeed merely in knowing a little less about it than the rest of men. The same may be said of our existence, present and future, of the essence of the Being to whom we owe it, and of the kind of worship he requires of us. Thus, nothing is more necessary than a revealed Religion, which may instruct us concerning so many diverse objects. Designed to serve as a supplement to natural knowledge, it shows us part of what was hidden, but it restricts itself to the things which are absolutely necessary for us to know. The rest is closed for us and apparently will be forever. A few truths to be believed, a small number of precepts to be practiced: such are the essentials to which revealed Religion is reduced. Nevertheless, thanks to the enlightenment it has communicated to the world, the common people themselves are more solidly grounded and confident on a large number of questions of interest than the sects  [35] of the philosophers have been.
    • Erin Hamson
       
      The role of religion is to fill in the gaps that man cannot discover on his own. The difference for us is that someday we will know.
  • The advantage men
  • found in enlarging the sphere of their ideas, whether by their own efforts or by the aid of their fellows, made them think that it would be useful to reduce to an art the very manner of acquiring information and of reciprocally communicating their own ideas. This art was found and named Logic. It teaches how to arrange ideas in the most natural order, how to link them together in the most direct sequence, how to break up those which include too large a number of simple ideas, how to view ideas in all their facets, and finally how to present them to others in a form that makes them easy to grasp. This is what constitutes this science of reasoning, which is rightly considered the key to all our knowledge. However, it should not be thought that it [the formal discipline of Logic] belongs among the first in the order of discovery. The art of reasoning is a gift which Nature bestows of her own accord upon men of intelligence, and it can be said that the books which treat this subject are hardly useful except to those who can get along without them. People reasoned validly long before Logic, reduced to principles, taught how to recognize false reasonings, and sometimes even how to cloak them in a subtle and deceiving form. [38]
    • Erin Hamson
       
      The last couple sentences are interesting because they talk about the human perspective timeline, how we seem to think that simply because something was recently discovered doesn't mean it didn't exist before then. Atom for examplke have always existed but we only recently have begun to discover their true nature.
  • Too much communication can sometimes benumb the mind and prejudice the efforts of which it is capable. If one observes the prodigies of some of those born blind, or deaf and mute, one will see what the faculties of the mind can perform if they are lively and called into action by difficulties which must be overcome.
  • The science of communication of ideas is not confined to putting order in ideas themselves. In addition it should teach how to express each idea in the clearest way possible, and consequently how to perfect the signs that are designed to convey it; and indeed this is what men have gradually done.
    • Erin Hamson
       
      The importance of both sharing ideas, for the general benefit of man, and discovering things on our own, for our progression.
  • The general system of the sciences and the arts is a sort of labyrinth, a tortuous road which the intellect enters without quite knowing what direction to take. Impelled, first of all, by its needs and by those of the body to which it is united, the intelligence studies the first objects that present themselves to it. It delves as far as it can into the knowledge of these objects, soon meets difficulties that obstruct it, and whether through hope or even through despair of surmounting them, plunges on to a new route; now it retraces its footsteps, sometimes crosses the first barriers only to meet new ones; and passing rapidly from one object to another, it carries through a sequence of operations on each of them at different intervals, as if by jumps. The discontinuity of these operations is a necessary effect of the very generation of ideas. However philosophic this disorder may be on the part of the soul, [57] an encyclopedic tree which attempted to portray it would be disfigured, indeed utterly destroyed.
  • It is only after having considered their particular and palpable properties that we envisaged their general and common properties and created Metaphysics and Geometry by intellectual abstraction. Only after the long usage of the first signs have we perfected the art of these signs to the point of making a science of them. And it is only after a long sequence of operations on the objects of our ideas that, through reflection, we have at length given rules to these operations themselves.
  • nature of the different minds that determines which route is chosen

  • And what this means is that if you look at a pedigree like this, and for example, here we have a mother and a father, girls are always round, boys are square. And here you'll see the mitochondrial DNA, it's donated to all of the children, but the fact is that these boys, when they mate, when they have offspring, they will no longer pass along her mitochondrial DNA, so it will be lost. And the only way the mitochondrial DNA can be transmitted is through one of her daughters, who in turn, have daughters.
  • Here's some other interesting principles. Mitochondrial DNA passes always from the mother, so when a fertilized egg is formed, Dad gives his chromosomes, but he doesn't donate for any, doesn't donate any mitochondrial DNA.
  • animals are related to one another. This is kind of a fun undertaking. Look at this. Why is it fun? Well it's, it's kind of an amusing idea, how often were cows domesticated during the history of humanity? How often were sheep domesticated? Pigs, water buffalos, and horses. And what you see here is that cattle were domesticated on two occasions, probably once in Western Asia, the middle east, and once in Eastern Asia. Sheep were domesticated twice, all modern sheep following these two families here

  • And that is, certain genes can evolve progressively over a long period of time, because they don't encode vital functions, or they may even be sequences between genes that don't encode phenotype at all. Imagine, for example, we have a situation were here we have a gene which encodes a vital function, like the eye, here's another gene that encodes another function, oh I don't know, a leg. And here we have intergenic sequences. After all, as you have learned by now, more than 96% of the DNA in our genome, doesn't encode proteins, and probably isn't even responsible for regulating genes. So these sequences, right in here, can mutate freely during the course of evolution, without having a deleterious effect on the phenotype of the organism. There's no evolutionary pressure to constrain the evolution of these genes
  • And many of these neutral mutations, which have no effect on organismic fitness, but are simply evolutionary neutral, are sometimes called polymorphisms. The term polymorphism, -morph is once again morphology, derives from the fact that species tend to be polymorphic, we don't all have blond hair, we don't all have brown eyes.
  • If you look at two chimpanzees living on opposite sides of the same hill in West Africa, they are genetically far more distantly related to one another, than any one of us, by a factor of 10 to 15. Two chimpanzees, they look exactly the same, they have the same peculiar habits, but they're genetically far more distantly-related than we are to one-another, than I am to any one of you, or than any one of you is to one another. And what does that mean? It means that, roughly speaking, the species of chimpanzees is, at least, 10 or 15 times older than our species are. We're a young species, chimpanzees probably first speciated three or four million years ago, if the paleontological record is, is accurate. Paleontology is the study of old, dusty bones, so you can begin to imagine when chimpanzee bones become recognizable in the earth.
  • And what you see already, in such small populations, is that for example, this male here has two girls, and right away, to the extent he had an interesting Y chromosome, that Y chromosome was lost from the gene pool. This girl, here, had an interesting mitochondrial DNA, but right away that's lost, because she has, she has just two boys. And what you see, in very rapid order, in small populations, there's a homogenization of the genetic compliment, just because the alleles are lost within what's called, genetic drif
  • And if you ask that question, the answer is that we all had a common ancestress who lived about 150,000 years ago. All of us trace our mitochondrial DNA to her. Does that mean that there was only one woman alive there, she's called, Mitochondrial-Eve, again, we don't know her name. Does that mean there was only one woman alive, well it doesn't mean that at all because of what I just told you, in small populations the proto-human population.
  • How much are all of our mitochondrial DNA are related to one another, how distantly related are they to one another, given the rate of evolution of mitochondrial DNA sequences?
  • So where do we all come from, all of us human beings? How closely related are we to one another? Here's, here's a measurement of the distances between different mitochondrial DNA's from different branches of humanity. And what you see is something really quite extraordinary and stunning. Here, you'll see that the people, the non-African lineages here and here, are actually relatively closely related to one another.
  • And by the way, all the genes that are present here, the alleles that are present here, can also be found in Africa, but in relatively small proportions in Africa
    • Erin Hamson
       
      Suggesting that all people came from Africa
  • So, what happens there, that's a testimonial to the tragic fate of the Indians, where the conquistadors from Spain came in, killed all the men, and took all the women, to be their brides. How else can you explain the fact that there's no Indian Y chromosomes, there's all, there is instead only European Y chromosomes.
  • When you do genetic counseling of family these days, one of the strictures is, that you never tell the family if the children have genetic polymorphisms that don't match that of the person whom they think is their father. They don't look like their, the person whom they regard as father, but that's always assumed to be a role of the genetic dice.
  • Here's a fun story I like to tell each year, and it's about the Cohen and Y chromosome, and you'll see what an amusing story this is, just from genetics. Now the name Cohen, in Hebrew means, a high priest, and you've heard people named Cohen, it's not such an uncommon name among the Jews. And it says, in the Bible, in Genesis and Exodus, that all the high priests in the Bible are the descendants of Aaron, the brother of Moses.
  • hen it should be the case that all male Cohen's should have the same Y chromosome, right?
  • Because keep in mind, any single affair with the milkman or the mailman, over 3,000 years, would've broke this chain of inheritance, any single incidence of non-paternity. It's a really astounding story, and it's hard, there can be no artifact to it, there's no bias in it, there's no other way to explain it.
  • And what they found was that all members of the, almost all members of the ruling cast among the Lembas, had the same Y chromosome, and the Y chromosome had exactly the same polymorphisms of the Cohen Y chromosome
  • What I'm telling you is that these two genes are totally interchangeable, that they are effectively indistinguishable from one another, functionally they have some sequence relatedness, but in terms of the way they program development, they are effectively equivalent. And what this means is that the progenitor of these two genes must've already existed at the time that the flies and we diverged, which six or seven-hundred million years ago, and in the intervening six or seven-hundred million years, these genes have been totally unchanged.
  • once the gene was developed, evolution could not tinker with it, and begin to change it in different ways, ostensibly because such tinkering would render these genes dysfunctional, and thereby would inactivate them, thereby depriving the organism of a critical sensory organ.
  •  
    An excellent discourse on who evolution works, and what it means for us today.

BBC News - Why companies watch your every Facebook, YouTube, Twitter move - 0 views

  • These days one witty Tweet, one clever blog post, one devastating video - forwarded to hundreds of friends at the click of a mouse - can snowball and kill a product or damage a company's share price.
  • It's a dramatic shift in consumer power. But what if companies could harness this power and turn it to their advantage?
  • At the most basic, these tools measure the volume of social media chatter. Researchers at Hewlett Packard showed that they can accurately predict a Hollywood movie's box office takings by counting how often it is mentioned on Twitter before it opens.

  • One European clothing company, popular with inner city youth in the United States, admits privately that its social media team is baffled by its customers' ever changing slang, and even the online Urban Dictionary provides little help.
  • Social media is quickly becoming a customer relationship management system, as companies have "for the first time access to people's minds in real-time," says Jorn Lyseggen. The tools on offer provide companies with dashboards that show trends, hot topics, the reach of brands, customer mood and how competitors are doing.
  • Social media may be all the buzz, but in reality "only a few firms get it [and use it], it's of peripheral interest for most", says Tom Austin at technology consultancy Gartner. Few realise that using social media has become much more than customer service and reputation management.
  • many social media tools are poorly integrated into the corporate workflow
  • But there are dangers. Financial Times columnist Lucy Kellaway warns that the obsession with social networking can make management lose focus.
  • To survive the world of social media, companies have to throw away their old marketing playbook.
  • "don't push... and don't pretend you are hip"
  • "Once companies have worked out that they should do something with social media, they usually don't know how to do it,"
  • "If you want to influence the people who influence your customers, that's a very powerful game, but it's also very dangerous if you get it wrong."
  • it's not about how many friends or followers somebody has, but whether they make an impact.
  • When Virgin America recently launched new routes from California to Toronto, it used Klout to identify a small group of social media "influencers" and gave them free flights. This generated thousands of tweets, triggered press coverage and delivered more immediate impact than traditional advertising.
  • "Consumers are spending their attention on social media," he says, but firms don't know how to repay them properly. "There's no manual for that yet."
  • Social media are dynamic, and today's Twitter may be tomorrow's forgotten website. "Don't assume that what works today will work tomorrow," says Tom Austin at Gartner. "Your model has to be continually adapted."

How I'd Hack Your Weak Passwords - 1 views

  • If you invited me to try and crack your password, you know the one that you use over and over for like every web page you visit, how many guesses would it take before I got it?
  • One of the simplest ways to gain access to your information is through the use of a Brute Force Attack. This is accomplished when a hacker uses a specially written piece of software to attempt to log into a site using your credentials.
  • And how fast could this be done? Well, that depends on three main things, the length and complexity of your password, the speed of the hacker's computer, and the speed of the hacker's Internet connection.
  •  
    Now, I could go on for hours and hours more about all sorts of ways to compromise your security and generally make your life miserable - but 95% of those methods begin with compromising your weak password. So, why not just protect yourself from the start and sleep better at night?

LDS.org - Ensign Article - Focus and Priorities - 0 views

  • principle of accountability also applies to the spiritual resources conferred in the teachings we have been given and to the precious hours and days allotted to each of us during our time in mortality.
  • The significance of our increased discretionary time has been magnified many times by modern data-retrieval technology. For good or for evil, devices like the Internet and the compact disc have put at our fingertips an incredible inventory of information, insights, and images. Along with fast food, we have fast communications and fast facts. The effect of these resources on some of us seems to fulfill the prophet Daniel’s prophecy that in the last days “knowledge shall be increased” and “many shall run to and fro”

  • our biggest need is a clearer focus on how we should value and use what we already have.
  • But to what purpose?
  • “knowledge of words, and ignorance of the Word,” in which “wisdom” is “lost in knowledge” and “knowledge” is “lost in information”
  • We have thousands of times more available information than Thomas Jefferson or Abraham Lincoln. Yet which of us would think ourselves a thousand times more educated or more serviceable to our fellowmen than they?
  • I could never complete my assigned task within the available time unless I focused my research in the beginning and stopped that research soon enough to have time to analyze my findings and compose my conclusions.
  • we must begin with focus or we are likely to become like those in the well-known prophecy about people in the last days—“ever learning, and never able to come to the knowledge of the truth” (2 Tim. 3:7).
  • But a bale of handouts can detract from our attempt to teach gospel principles with clarity and testimony.
  • Stacks of supplementary material can impoverish rather than enrich, because they can blur students’ focus on the assigned principles and draw them away from prayerfully seeking to apply those principles in their own lives.
  • Each of us should be careful that the current flood of information does not occupy our time so completely that we cannot focus on and hear and heed the still, small voice that is available to guide each of us with our own challenges today.
  • Our priorities determine what we seek in life.
  • “a man’s life consisteth not in the abundance of the things which he possesseth”
  • Our priorities are most visible in how we use our time.
  • Good choices are especially important in our family life. For example, how do family members spend their free time together? Time together is necessary but not sufficient.

  • We thought maybe we’d put together a few temporary, informal memos on network protocols, the rules by which computers exchange information
  • Less important than the content of those first documents was that they were available free of charge and anyone could write one. Instead of authority-based decision-making, we relied on a process we called “rough consensus and running code.”

  • Our intent was only to encourage others to chime in, but I worried we might sound as though we were making official decisions or asserting authority.
  • It probably helped that in those days we avoided patents and other restrictions; without any financial incentive to control the protocols, it was much easier to reach agreement.
  • This was the ultimate in openness in technical design and that culture of open processes was essential in enabling the Internet to grow and evolve as spectacularly as it has
  • we always tried to design each new protocol to be both useful in its own right and a building block available to others. We did not think of protocols as finished products, and we deliberately exposed the internal architecture to make it easy for others to gain a foothold.

      to me it's too much. we are spending our lives online in a world that can be valuable, but most of the time is not. it is so hard to balance time online with time doing other productive things. So much of our lives requires us to be on the computer, ugh.

    So, this begs the question... are we spending too much time on the Internet, too little? Or are we using our time online poorly or wisely? (We - personally, nationally, globally).
