Quiz-Samasya 2019 finals

  1. 1. SAMASYA FINALS
  2. 2. ROUND 1 SCIENCE FOR COMMUNICATION  12 QUESTIONS  +10 FOR POUNCE/BOUNCE
  3. 3.  1.  If something is moving through the air at some velocity, it experiences a drag force due to air resistance. The drag force increases exponentially with velocity. Thus X needs to exert an exponentially increasing force to the ground. Also X needs to be resistant to sweltering heat, as friction is one of the implications of what he does best.  Who is X?
  4. 4. THE FLASH
  5. 5.  2.  Beams of light are tricky to contain because photons are very difficult to turn around or stop mid-air. Perhaps the easiest way to create a 3-foot-long beam would be a mirror opposite to reflect the light.  Also ,the power of a visible light laser pointer would need to be upped by a factor of about a thousand before it could do any damage, and a laser of that power would require an extensive cooling system.  These are some of the reasons why people have questioned the authenticity of a very famous object. Which object?
  6. 6. LIGHTSABER
  7. 7.  3. In Boston, lived ____, as did ____, Who gained mgh on a hill. In their liquid pursuit, ____ tripped on some trash in the sand. He changed his potential To kinetic, torrential, But not before grabbing ____'s hand How do we more popularly know this scientific rendition?
  8. 8. JACK AND JILL
  9. 9.  4.  What is the physics concept being demonstrated here and by whom? 
  10. 10. MOMENT OF INERTIA WALTER LEWIN
  11. 11.  5.  "In an ever-changing world it is a single point of consistency. If my life were expressed as a function on a four-dimensional Cartesian coordinate system, that spot, at the moment I first sat on it, would be (0,0,0,0).”  What is (0,0,0,0)?
  12. 12. SHELDON’S SPOT
  13. 13.  6.  Metamaterials are tiny, artificial structures are smaller than the wavelength of light and exhibit negative electromagnetic properties that affect how an object interacts with electromagnetic fields. In 2006, Duke University's David Smith took an earlier theory posed by English theoretical physicist John Pendry and used it to create a metamaterial capable of distorting the flow of microwaves. Smith's metamaterial fabric consisted of concentric rings containing electronic microwave distorters. When activated, they steer frequency-specific microwaves around the central portion of the material.  What highly popular fictional object could these metamaterials make a reality in the near future?
  14. 14. THE INVISIBILITY CLOAK
  15. 15.  7.  A self-centered person is excessively concerned with himself and his own needs. Self- centered people tend to ignore the needs of others and only do what's best for them. In the seventeenth century, however, self-centered meant "fixed or stationary."  Give us both the scientific concept, and the metaphor related to it, to describe the above?
  16. 16. HELIOCENTRIC MODEL/THE WORLD REVOLVES AROUND THEM
  17. 17.  8.  The formula for converting between kinetic energy and thermal energy is 1/2mv2 = mcT. The average __________ weighs about 0.4kg, the average ____ has a velocity of 11 m/s and average ______ weighs 1kg, and has a specific heat capacity of 2720 J/kgc and has to reach a temperature of 2050C. 1 average ____ would generate a temperature increase of 0.0089 degrees celsius. Thus the velocity needs to be 1665.65 m/s.  What question stands answered by the above, which recently put many social media sites into a thinking fix?
  18. 18. HOW FAST SHOULD ONE SLAP A CHICKEN TO COOK IT?
  19. 19.  9.  X is an annual contest ,started in 2008 by science journalist John Bohannon,under the auspices of continuing sponsors Science Magazine and the American Association for the Advancement of Science. The winners are chosen by an expert panel of scientists and artists. X has become popular in trying to explain a usually mundane concept in an interesting and expressive way.  How is this done?
  20. 20. 10. What scientific concept is depicted here?
  21. 21. CONSERVATION OF ANGULAR MOMENTUM
  22. 22.  11.  The shortcomings of traditional indicators and the multitude of scientific performance dimensions led to the development of innovative, alternative measures. Altmetrics is “the study and use of scholarly impact measures based on activity in online tools and environments. The goal of this paper is to investigate whether ________ _____ for unpublished manuscripts that are uploaded to the Internet could be used as an early indicator of the future impact of the scientific work, as ________ _____ always express a clear positive semantic meaning.  Fill in the blanks with a possible indicator.
  23. 23. FACEBOOK LIKES

  50. 50.  5.  The first-ever commercial X, dubbed the "Radarange" stood at nearly six feet tall and weighed 750 pounds, according to the Southwest Museum of Engineering, Communications, and Computation. It also required a water line to cool the magnetron tube. That first model was priced at around $5,000 in 1947, the equivalent of approximately $53,000 today. The models today are more compact and affordable and are present in nearly all houses.  ID X
  51. 51. MICROWAVE OVENS
  52. 52.  6.  The X girls were a group of female factory workers who contracted a form of poisoning from painting watch dials with self-luminous paint, which contained X. X was initially used in dials because it was self-emitting and did not require any external energy source. However, the poisoning of the X girls led to a stop in the usage of X in watch dials and was soon replaced by Tritium and Strontium aluminate.  ID X.
  53. 53. RADIUM
  54. 54.  7.  This term was originally coined by Eugene Wigner, who initially believed in an alternate model, but was soon convinced by the evidence for this current most popularly accepted model. It seemed a little out of the ordinary for him, and thus led to the coining of the word. This is observed in the elements: Helium, Oxygen, Calcium, Nickel, Tin, Lead and the hypothetical Unbihexium.  What is the term?
  55. 55. MAGIC NUMBERS
  56. 56.  8.  This is a simplified version of a graph, which was one of the most important discrepancies between theoretical predictions and observed data, in the beginning of last century. What problem is being depicted in this graph?
  57. 57. GALAXY ROTATION PROBLEM
  58. 58.  9.  Although primarily famous in a completely different field, X was where the World Wide Web was developed, and X put the software in Public domain, and even made it open license for maximum dissemination. X has now recently started a project to restore the first ever website, info.X.ch, and also has claims to being associated with one of the first photos on the web, although indirectly.  ID X.
  59. 59. CERN
  60. 60.  10.  CPA lasers opened up an industry for more precise machining of a wide range of materials. This has found particular use in the machining of brittle materials, used extensively on electronic devices, which is made up of alkali-aluminosilicate and has great surface strength.  What have these CPA lasers improved production in, without which most of us would have a tough time?
  61. 61. GLASSES FOR SMARTPHONES
  62. 62.  11.  X Y is a collection of biographical essays ,published by the Indian Academy of Sciences.
