Are Solar Sails the Future of Space Travel? - 0 views

    • Virinchi Tadikonda
       
      Innovation is one of the most important factors of space travel. This simple design can turn into something that we can use to potentially travel vast distances. 
  • But it took a long time for solar sails to go from concept to reality. The first successful demonstration of the propulsion system didn't come until 2010, when Japan's Ikaros probe deployed its 46-foot-wide (14 m) sail and became the first craft ever to cruise through space on the backs of photons.

      This just tells us that nothing comes easy, and that we might actually be a long distance away from achieving the next space milestone, which is setting foot on another planet. 
  • The $27 million Sunjammer mission, which takes its name from the Arthur C. Clarke story, will use a sail built by California-based company L'Garde that measures 124 feet (38 m) on a side. The sail, made of an advanced material called Kapton, is just 5 microns (about 0.0002 inches) thick. It weighs less than 70 pounds (32 kilograms) and packs down to the size of a dishwasher, NASA officials have said.

      As much as funds are being cut from NASA and budget cuts are taking a toll on all space related activities, research is definitely crucial. But we do not hear about these researches in the news.

      Prevention of disasters is one of the most important security aspects of technology. This kind of probes will enhance safety among the public but the one thing I see is that the media has not covered this. It is not a big aspect of technology it seems, and I disagree. 
  • And some researchers have even higher hopes for solar sails, suggesting that a truly enormous sail —one the size of Texas, for example — could send a spaceship to another star system in just a few centuries. (A space-based laser would have to shine a powerful beam on the sail as the craft moved farther and farther away from the sun, however.)   
    • Virinchi Tadikonda
       
      This is the definition of future research for the benefit of society in the generations to come. This kind of technology can potentially unite us with another Earth. Unfortunately this is the first one I have found about any kind of research with solar panels in media. 
  • Several upcoming missions aim to harness the subtle push of sunlight, using gossamer "solar sails" to cruise through the heavens like boats through the sea.
  • A spacecraft equipped with a sail 1,300 feet (400 meters) wide, for example, could travel 1.3 billion miles (2.1 billion kilometers) per year, allowing it to escape the sun's sphere of influence in just a decade or so, according to researchers behind the Interstellar Probe, a NASA concept mission proposed about 15 years ago.

Simulacra and Simulation - Wikipedia, the free encyclopedia - 1 views

  • "Simulacra and Simulation" breaks the sign-order into 4 stages: The first stage is a faithful image/copy, where we believe, and it may even be correct, that a sign is a "reflection of a profound reality" (pg 6), this is a good appearance, in what Baudrillard called "the sacramental order". The second stage is perversion of reality, this is where we come to believe the sign to be an unfaithful copy, which "masks and denatures" reality as an "evil appearance—it is of the order of maleficence". Here, signs and images do not faithfully reveal reality to us, but can hint at the existence of an obscure reality which the sign itself is incapable of encapsulating. The third stage masks the absence of a profound reality, where the simulacrum pretends to be a faithful copy, but it is a copy with no original. Signs and images claim to represent something real, but no representation is taking place and arbitrary images are merely suggested as things which they have no relationship to. Baudrillard calls this the "order of sorcery", a regime of semantic algebra where all human meaning is conjured artificially to appear as a reference to the (increasingly) hermetic truth. The fourth stage is pure simulation, in which the simulacrum has no relationship to any reality whatsoever. Here, signs merely reflect other signs and any claim to reality on the part of images or signs is only of the order of other such claims. This is a regime of total equivalency, where cultural products need no longer even pretend to be real in a naïve sense, because the experiences of consumers' lives are so predominantly artificial that even claims to reality are expected to be phrased in artificial, "hyperreal" terms. Any naïve pretension to reality as such is perceived as bereft of critical self-awareness, and thus as oversentimental.

Barcode - Wikipedia, the free encyclopedia - 0 views

  • A barcode is an optical machine-readable representation of data relating to the object to which it is attached. Originally barcodes systematically represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional (1D). Later they evolved into rectangles, dots, hexagons and other geometric patterns in two dimensions (2D). Although 2D systems use a variety of symbols, they are generally referred to as barcodes as well. Barcodes originally were scanned by special optical scanners called barcode readers. Later, scanners and interpretive software became available on devices including desktop printers and smartphones.
  •  
    Barcodes are symbols just like any other, but they can only be read by computers! They're kind of like paintings for computers.

    This is a painting by Rembrandt from the Baroque. I chose to link this painting because before computer displays, one of the methods of visual exploration to extra-reality was through artwork. Rembrandt crafted the painting to show exactly what he wanted, not the truth.

The Radio as New Technology: Blessing or Curse? A 1929 Debate » - 0 views

  • Accommodated as we are to mass media, we must work to imagine the impact of commercial radio broadcasting in its early years. From the late 1800s, new electronic devices had been expanding the realm of shared human experience — people conversed on telephones, sent news through telegrams, played records on phonographs, and enjoyed films in local theaters. But until the radio, nothing offered such widely shared simultaneous mass experience. By turning on your radio set, you could listen to a jazz band, baseball game, religious service, even a president’s speech, live, along with millions of fellow listeners.

  • Children who received at least three years (M = 4.6 years) of instrumental music training outperformed their control counterparts on two outcomes closely related to music (auditory discrimination abilities and fine motor skills) and on two outcomes distantly related to music (vocabulary and nonverbal reasoning skills). Duration of training also predicted these outcomes. Contrary to previous research, instrumental music training was not associated with heightened spatial skills, phonemic awareness, or mathematical abilities

The power of music - 1 views

  • Anthony Storr, in his excellent book Music and the Mind, stresses that in all societies, a primary function of music is collective and communal, to bring and bind people together
  • People with Tourette's syndrome—including many I know who are professional musicians—may become composed, tic-free, when they listen to or perform music; but they may also be driven by certain kinds of music into an uncontrollable ticcing that is entrained with the beat
  • There is a wide range of sensitivity to the emotional power of music, ranging from virtual indifference at one extreme (Freud was said to be indifferent to music, and never wrote about it), to a sensitivity that can barely be controlled. Individuals with Williams syndrome, for example, though they have severe visual and cognitive defects, are often musically gifted, and usually extravagantly sensitive to the emotional impact of music. I have seen few sights more extraordinary than a group of 40 young people with Williams syndrome breaking into uncontrollable weeping at tender or sad music, or uncontrollably excited if the music is animated.

  • Perseverative music has much more the character of a cerebral automatism, suggesting cerebral networks, perhaps both cortical and subcortical, caught in a circuit of mutual excitation. I do not think there are comparable phenomena with other types of perception—certainly not with visual experience. For instance, I am a verbal creature myself, and though sentences often permute themselves in my mind and suddenly surface as I am writing, I never have verbal ‘earworms’ comparable with musical ones.

This is your brain on music - CNN.com - 1 views

  • The results: The patients who listened to music had less anxiety and lower cortisol than people who took drugs. Levitin cautioned that this is only one study, and more research needs to be done to confirm the results, but it points toward a powerful medicinal use for music.
  • Among participants, the researchers found synchronization in several key brain areas, and similar brain activity patterns in different people who listen to the same music. This suggests that the participants not only perceive the music the same way, but, despite whatever personal differences they brought to the table, there's a level on which they share a common experience.

How Do Companies Make Any Money in Digital? - 0 views

  • The entire infrastructure of the ad industry has been re-architected, and redeployed.  The critical change is that the infrastructure is now open across the entire "stack" of technologies, and pretty much every major platform is open and extensible. This means that new companies can innovate on specific problems without having to build out their own copy of the stack.  They can build the pieces they care about, the pieces that add specific value and utility for specific purposes – e.g. New Monetization Models for Publishers and Brand Advertisers, New Ad Formats, New Ad Inventory Types, New Impression Standards, New Innovation across Mobile, Video and Social, and so on.

Future of Human Space Exploration Could See Humans on Mars, Alien Planets - 0 views

  • Closer to home, private industries like Mars One seek to establish a permanent settlement on the Red Planet. At the Smithsonian Magazine's "The Future is Here Festival" in Washington, D.C. this month, former astronaut Mae Jemison and NASA engineer Adam Steltzner spoke optimistically about the future of manned space exploration
    • Virinchi Tadikonda
       
      The way that planet Earth and our Solar System is operating is that the sun expands everyday, and planets revolving around the sun. The sun will eventually grow and expand with the future being sucking in all the planets, killing all life. Future expansion of other planets is necessary. 
  • Although the idea that bacteria — and life — could hitch a ride on traveling rocks to spread life to other planets is not new, Steltzner suggested a deliberate program that sounds more like science fiction than science fact. Such bacteria could carry our genome and the instructions to reassemble it after landing on a planet (and, one assumes, after the planet has been terraformed to support such life). Steltzner described the process as "printing human beings organically over time."
    • Virinchi Tadikonda
       
      Life in other planets is not at all impossible. There are many scientific methods to start life, the only question is how to do it, and will the life survive? 
  • In addition to curiosity-motivated exploration, Steltzner pointed out that as long as humans remain on a single planet, we are at risk of extinction when disaster strikes. "Our real estate portfolio suffers from a concentration of risk," he said.
    • Virinchi Tadikonda
       
      An important note is that we have limited resources on planet Earth. Once those resources are extinct, there must be exploration elsewhere from either Space, or deep in the unexplored regions of the oceans.

  • "Technology didn't slow us down getting to the moon," Steltzner said. "Technology won't slow us down getting to Mars."
    • Virinchi Tadikonda
       
      The problem with this technology is that all the information that was used for getting to the moon was lost. The old computers got replaced and the people who worked to get astronauts to the moon retired. The key this time around is to not lose the information. In Kennedy's presidency, it took a long time to get all the components together. Now that technology is more advanced, it should take less time to get to the moon, and should be a straight shot to Mars. 
  • Mars may be one of the closest planets humans want to colonize, but it certainly isn't the only one. Mae Jemison described the 100-Year Starship project to an interested audience. Funded by NASA's Ames Research Center and the Defense Advanced Research Projects Agency (DARPA), the 100-Year Starship project aims to develop the tools and technology necessary to build and fly a spaceship to another planetary system within the next 100 years. The program isn't necessarily concerned with building the ship itself as much as it seeks to foster innovation and enthusiasm for interstellar travel.
    • Virinchi Tadikonda
       
      The method of transportation is going to be very difficult. The researching that is in progress and takes a while to accomplish, obviously. Maybe this is NASA's plan to not release to the public yet? 
  • Though many people object to funding the space program when there are humanitarian needs that have to be met on Earth, Jemison points out that such exploration often leads to innovation and unexpected technology that make an impact on Earth-based programs. "I believe that pursuing an extraordinary tomorrow will create a better world today," she said.
    • Virinchi Tadikonda
       
      The original space launches did not revolve around trying to put up satellites, rather to explore space. Since then, satellites have been launched, telescopes have also been put up. Who knows what other technological aspects can be added once funding is no longer cut and innovation is big again?
