  1. Hello.
  2. My name is Loretta.
  3. And today I will be talking about the mathematical concept of bitches
  4. and most importantly, their use
  5. in real life
  6. started.
  7. You may be wondering what our major
  8. they have
  9. ordered rectangular array of number
  10. here,
  11. the road at the state of horizontal elements and the columns at the set of vertical
  12. and notices are always represented
  13. by a capital at
  14. the elements themselves can be number
  15. function letters,
  16. a really anything
  17. right
  18. get into the uses of matrices in real life.
  19. So we have always used matrices in real life. Have never realised
  20. this. As you can see on the slide in front of you,
  21. if you ever used
  22. as spreadsheet like excess,
  23. you have used matrices unknowingly
  24. to here under under table in front of you.
  25. We have two students who have written to,
  26. and there
  27. marked are given
  28. that is 22 26 25
  29. 21.
  30. So why? If you want to put these data in a more concise manner
  31. without having to put the headers of rows and columns,
  32. we can do that using matrices.
  33. So when you are transferring data, it's easier.
  34. And if both parties know what these rows and columns are.
  35. It's very easy to understand
  36. now. Then let's look into
  37. it uses
  38. in life
  39. Well, First of all, let's start with
  40. the usage of
  41. matrixes in Stein's and especially, physics
  42. would require a video.
  43. But here is one interesting aspect. Matrixes on you
  44. in
  45. kind.
  46. So in front of you is what is causing RGB metric be valley of three separate colo.
  47. You are
  48. that primary in nature
  49. to any colour on the pixel can be done with varying value of our G B,
  50. the stand for red, green
  51. and blue, the primary and basic colours.
  52. And these values are in that order only in the form of red, then green and then blue.
  53. For example. In 23 you can t range,
  54. which has only
  55. read
  56. part of the Matrix
  57. as the highest number, which is 2 55.
  58. Similarly, with green and blue
  59. but yellow hana
  60. is a mix of
  61. red and green, so
  62. yellow would have
  63. the high value for red
  64. and green.
  65. This is mainly used
  66. in astronomy, especially
  67. when we send satellites to other planets and other
  68. tele bodies.
  69. What we do is
  70. when the satellite captured image,
  71. it is much easier for him to transfer these numbers
  72. in the form from metric.
  73. The values are transferred from the satellite
  74. to Earth, and then they are recreated in a computer
  75. rather than standing the image themselves between require
  76. a lot of data, transfer it
  77. at the satellite, maybe millions of kilometres away.
  78. So if you ever think of pursuing astronomy and the career,
  79. this will come
  80. in use for you
  81. moving on
  82. to one of the main uses
  83. of matrix,
  84. which is in computer science.
  85. There are a lot of aspects of computer scientists that
  86. news matrix
  87. one of the most important. One is encryption.
  88. Encryption is basically when you have information
  89. already in the former from Matrix,
  90. you apply logic to it
  91. and it is saved and a different form of metal.
  92. So,
  93. given the example on screen,
  94. there is a matrix.
  95. Abby
  96. and CD are given in that order,
  97. but we apply a logic to it, which is criss cross
  98. and the positions swap for now, D. B and
  99. I, my new matrix.
  100. So any potential hacker might see the encrypted form,
  101. and it would not make sensitive.
  102. But if you apply the reverse logic,
  103. it will make sense.
  104. So this is one aspect of where
  105. matrixes are used in computer science.
  106. The next expect is taken August
  107. Sekera Graffiti is the process of hiding secret
  108. data underneath any form of media
  109. that his images
  110. audio, video or even text.
  111. So, as you can see on screen, there is a matrix on my left
  112. left image
  113. is extracted from the image on the rights to any person
  114. with the knowledge of matrix.
  115. And a bit of coding
  116. can use steganography as a tour of hiding.
  117. Secret Information
  118. taken on Gaddafi does require some pre required knowledge,
  119. and
  120. it can be used if you want to share
  121. any data with your friend.
  122. And this has become increasingly necessary in our world, which is filled with
  123. cyber threats and attacks.
  124. Finally, let's talk about the money
  125. and how matrices are news
  126. businesses
  127. and economic
  128. businesses
  129. may use
  130. metrics is to
  131. track EGY
  132. where they changed one variable at a time
  133. and see
  134. the output of that
  135. So
  136. company might have a product and they advertise it,
  137. and whatever money they get,
  138. they are saving it
  139. and then planning ahead for the future as the first company
  140. and that has resulted in a law.
  141. So they tested new strategy this time
  142. changing the variable of saving to remain
  143. so they have a product,
  144. they advertise it,
  145. they reinvest the money they make
  146. and that results them in a
  147. profit.
  148. This is the use
  149. of matrix is.
  150. And if you find it's as the CEO of a company,
  151. how you would like to start air own start up
  152. you might want to use matrix is to ensure that you have
  153. profit every time.
  154. Right? So that's all about
  155. News of Matrix is in real lives and professions.
  156. Hope you enjoy. Thank you very much.
