1 00:00:10,520 --> 00:00:14,670 Hello, everyone, and welcome to day to day in this video. 2 00:00:14,690 --> 00:00:23,000 I would like to introduce you to the few times that are related to the shape of the Earth and understand 3 00:00:23,000 --> 00:00:24,740 what this means. 4 00:00:25,100 --> 00:00:27,600 The eye is not perfect there. 5 00:00:27,890 --> 00:00:35,450 So the eye is not completely spherical with the circumference of forty thousand seventy five kilometers. 6 00:00:36,050 --> 00:00:38,120 That would actually make another thing. 7 00:00:38,120 --> 00:00:45,290 Is it is the argument perfectly spherical, but it's not then is, of course, a couple graphic inventions, 8 00:00:45,290 --> 00:00:49,130 which includes multi valleys, kids, etc.. 9 00:00:49,130 --> 00:00:56,930 When we are talking about in comparison to the rest of the diameters of the event, the less mundane 10 00:00:56,930 --> 00:01:00,350 to not really the whole lot of radiation. 11 00:01:00,800 --> 00:01:08,740 So actually, if we are going on, we are talking about Trayvon Martin and the presentations, we actually 12 00:01:08,750 --> 00:01:15,890 often have to exaggerate the double cross examination of different areas or you get those up. 13 00:01:16,310 --> 00:01:23,900 So, yes, there is a double graphic invitation, but when we are talking about the empire, it's not 14 00:01:23,900 --> 00:01:24,630 very much. 15 00:01:24,640 --> 00:01:30,050 There are values are not much lower than the surface of the Earth. 16 00:01:30,410 --> 00:01:38,030 For example, the peak of Mount Everest is only eight thousand eight hundred forty eight meters above 17 00:01:38,030 --> 00:01:46,670 the sea level, compared to the arch diameter of approximately 12 million seven hundred fifty six thousand 18 00:01:46,670 --> 00:01:48,120 two hundred meters. 19 00:01:48,580 --> 00:01:55,850 So as far as it goes, when we are talking about the shape and the size of the entire hour, we do not 20 00:01:55,850 --> 00:01:58,100 have to worry about that much. 21 00:01:58,280 --> 00:02:04,370 What are the things that we have to worry about is the fact that the earth is squashed. 22 00:02:04,670 --> 00:02:13,220 The order is actually a little bit shorter from waterborne detection than it is if you are talking about 23 00:02:13,540 --> 00:02:14,150 meters. 24 00:02:14,180 --> 00:02:18,220 As you can see in the first diagram, the earth is squashed. 25 00:02:18,740 --> 00:02:20,990 This is enough to make that thinking. 26 00:02:21,290 --> 00:02:29,980 Then the ongoing geographical information system much more difficult than if we were working with upmarket 27 00:02:29,990 --> 00:02:30,350 food. 28 00:02:30,800 --> 00:02:41,290 Even though our planet is sick, it is not perfect sphere because before then the ultra did not fall 29 00:02:41,300 --> 00:02:49,820 and we saw bones like flat the observation, wobbly motion and the other forces are making the planet 30 00:02:49,840 --> 00:02:51,860 GTP shape very slowly. 31 00:02:52,160 --> 00:02:54,010 But extend Loung. 32 00:02:54,380 --> 00:03:03,710 This squishiness of the earth gives us Watchguard as Sammy Manjit and me my ex's is the ripple effect 33 00:03:03,710 --> 00:03:04,640 is very good. 34 00:03:04,820 --> 00:03:12,530 Then they would just stop about the diameter and the debris and that would be constant in all directions. 35 00:03:12,920 --> 00:03:20,690 But because that does not work, that mistaken may have some major axis that goes from Ecliptic on the 36 00:03:20,690 --> 00:03:22,550 other side of the equator. 37 00:03:22,790 --> 00:03:30,850 And the may mean that axis, which is shorter, which goes from not falling down to this hour or so, 38 00:03:30,860 --> 00:03:37,210 but we got a shape that is a sphere that we built and squashed a little bit. 39 00:03:37,670 --> 00:03:43,130 But if we talk about sphere and squashed it, it forms ellipsoid. 40 00:03:43,460 --> 00:03:46,270 So that's the terminology we use. 41 00:03:46,730 --> 00:03:53,270 So say we are trying to construct the model of the many Denge when we are talking about the precious 42 00:03:53,270 --> 00:04:02,540 measurement, which is not based on sphere, but it is based on little bit squashed spear like ellipsoid. 43 00:04:02,900 --> 00:04:10,300 Sometimes it is also called a satellite because it is so close to say it's almost a sphere. 44 00:04:10,730 --> 00:04:14,920 So sometimes we can hear term Sparerib, Esman. 45 00:04:15,410 --> 00:04:23,180 But what does that I mean, it just means you have taken a sphere and squashed it a little bit and we 46 00:04:23,180 --> 00:04:27,530 have a little bit better representation about the shape of the earth. 47 00:04:27,830 --> 00:04:33,320 The speed of light is three dimensional shape created from two dimensional ellipse. 48 00:04:33,710 --> 00:04:37,160 The Ellipse is an oval with immagine axis. 49 00:04:37,160 --> 00:04:42,560 That is the longer axis and in my mind, axis, that is the shorter axis. 50 00:04:43,040 --> 00:04:49,370 As you can see here in the diagram, we have the shorter axis that basically minorities' and the longer 51 00:04:49,370 --> 00:04:51,590 axis that is the axis. 52 00:04:51,590 --> 00:04:59,780 For example, if the Ellipse, the shape of the rotated figure is the strike that is another, then 53 00:05:00,050 --> 00:05:06,580 it is also true that it is not only squashed, but it's also lumpy. 54 00:05:07,070 --> 00:05:10,010 These are the technical terms, the artist GWI. 55 00:05:10,220 --> 00:05:19,010 And, Nancy, aside from the topography, the they have lately big lunch lady Whitlams across the surface 56 00:05:19,010 --> 00:05:19,800 of the earth. 57 00:05:19,970 --> 00:05:23,100 So here you can see the lumpiness of the earth. 58 00:05:23,590 --> 00:05:29,740 Sometimes it's very important for those lamps across the surface of the earth. 59 00:05:30,140 --> 00:05:31,760 Then we are doing that. 60 00:05:31,760 --> 00:05:34,600 We are generating something called joy. 61 00:05:35,180 --> 00:05:42,870 So joy is the count of the lumpiness of the Earth as well as the squashed ness of the Earth. 62 00:05:43,760 --> 00:05:49,750 Now, please let us understand different ways of models and the shape of the Earth. 63 00:05:50,450 --> 00:05:56,050 This is a representation of the Earth and one level of generalization. 64 00:05:56,060 --> 00:06:03,710 If they want to get a little bit bigger than that, they watch this very little bit and we get it into 65 00:06:03,710 --> 00:06:04,590 an ellipsoid. 66 00:06:05,240 --> 00:06:12,220 And if you want to make it even better representation of us, then we go into account. 67 00:06:12,270 --> 00:06:14,920 It's lumpiness and squashed nuts. 68 00:06:14,930 --> 00:06:18,500 And so we produce a joint that's. 69 00:06:18,800 --> 00:06:20,640 I hope you like the video stadion.
