      <p xml:id="p2" begin="00:00:06.300" end="00:00:09.270" region="bottomCenter">su trabajo era realmente el inicio de la ciencia</p>
      <p xml:id="p3" begin="00:00:09.470" end="00:00:13.790" region="bottomCenter">la gente piensa que la ciencia para así comenzó hace mucho tiempo con los griegos y</p>
      <p xml:id="p4" begin="00:00:14.100" end="00:00:19.930" region="bottomCenter">quizá con los árabes allí, pero en realidad la ciencia comenzó con este hombre</p>
      <p xml:id="p5" begin="00:00:20.250" end="00:00:21.900" region="bottomCenter">y ¿por qué digo que</p>
      <p xml:id="p6" begin="00:00:22.300" end="00:00:26.940" region="bottomCenter">bueno, miremos a los instrumentos que utilizó para observar los planetas</p>
      <p xml:id="p7" begin="00:00:27.190" end="00:00:30.760" region="bottomCenter">fue la primera persona que realmente parcela con exactitud</p>
      <p xml:id="p8" begin="00:00:31.020" end="00:00:33.350" region="bottomCenter">¿cómo los planetas avanzado en los cielos</p>
      <p xml:id="p9" begin="00:00:33.630" end="00:00:36.830" region="bottomCenter">y el calamar él habilidad</p>
      <p xml:id="p10" begin="00:00:37.040" end="00:00:40.600" region="bottomCenter">que la gente que hizo este habían separado vamos a saltar</p>
      <p xml:id="p11" begin="00:00:40.840" end="00:00:43.040" region="bottomCenter">este absolutamente hermosa grabado</p>
      <p xml:id="p12" begin="00:00:43.220" end="00:00:49.090" region="bottomCenter">que era necesario realizar esas mediciones que son muy muy difícil sin realmente bien telescopios</p>
      <p xml:id="p13" begin="00:00:49.410" end="00:00:53.440" region="bottomCenter">se puede ver que se hicieron mediciones precisas de ángulos</p>
      <p xml:id="p14" begin="00:00:53.660" end="00:00:56.000" region="bottomCenter">en ese momento por tyco traído ok</p>
      <p xml:id="p15" begin="00:00:56.270" end="00:00:56.990" region="bottomCenter">y aquí</p>
      <p xml:id="p16" begin="00:00:57.110" end="00:00:58.920" region="bottomCenter">son algunos de su nariz</p>
      <p xml:id="p17" begin="00:00:59.140" end="00:00:59.760" region="bottomCenter">ahora</p>
      <p xml:id="p18" begin="00:00:59.920" end="00:01:02.320" region="bottomCenter">resulta que murió</p>
      <p xml:id="p19" begin="00:01:03.140" end="00:01:05.950" region="bottomCenter">tras el nombre muchas de estas mediciones</p>
      <p xml:id="p20" begin="00:01:06.220" end="00:01:09.810" region="bottomCenter">y su técnico, niza bose fue</p>
      <p xml:id="p21" begin="00:01:09.980" end="00:01:10.500" region="bottomCenter">kepler</p>
      <p xml:id="p22" begin="00:01:11.000" end="00:01:14.220" region="bottomCenter">y esto es muy afortunados porque kepler tenía una brillante</p>
      <p xml:id="p23" begin="00:01:14.340" end="00:01:16.000" region="bottomCenter">así matemático</p>
      <p xml:id="p24" begin="00:01:16.300" end="00:01:17.070" region="bottomCenter">y él</p>
      <p xml:id="p25" begin="00:01:17.290" end="00:01:19.910" region="bottomCenter">tomó todas las mediciones de tyco traído che</p>
      <p xml:id="p26" begin="00:01:20.250" end="00:01:21.850" region="bottomCenter">y</p>
      <p xml:id="p27" begin="00:01:21.990" end="00:01:25.020" region="bottomCenter">tuvo que calcular detenidamente</p>
      <p xml:id="p28" begin="00:01:25.180" end="00:01:28.840" region="bottomCenter">las órbitas de los planetas esto es extremadamente dificultad de hecho</p>
      <p xml:id="p29" begin="00:01:29.170" end="00:01:29.890" region="bottomCenter">él</p>
      <p xml:id="p30" begin="00:01:30.030" end="00:01:35.000" region="bottomCenter">hizo su propio tablas saben ordenadores y calculadoras</p>
      <p xml:id="p31" begin="00:01:35.210" end="00:01:40.100" region="bottomCenter">se utiliza mucho tablas para hacer e especialmente matemáticas muy complejo</p>
      <p xml:id="p32" begin="00:01:40.290" end="00:01:42.380" region="bottomCenter">división era extremadamente difícil</p>
      <p xml:id="p33" begin="00:01:42.790" end="00:01:47.630" region="bottomCenter">y él estos escritos en estos lo que se llama rudolf encontrar tablas</p>
      <p xml:id="p34" begin="00:01:48.180" end="00:01:49.480" region="bottomCenter">y la clave</p>
      <p xml:id="p35" begin="00:01:49.650" end="00:01:51.670" region="bottomCenter">pero creo que descubre</p>
      <p xml:id="p36" begin="00:01:51.920" end="00:01:57.350" region="bottomCenter">es sumamente importante y aquí vemos algunas de las ideas originales</p>
      <p xml:id="p37" begin="00:01:57.460" end="00:02:02.750" region="bottomCenter">sobre los movimientos de los planetas y el particular que fue más importantes fue este</p>
      <p xml:id="p38" begin="00:02:02.900" end="00:02:04.840" region="bottomCenter">que es la órbita de marte</p>
      <p xml:id="p39" begin="00:02:05.080" end="00:02:08.260" region="bottomCenter">y vemos que las órbitas de marte no es un círculo</p>
      <p xml:id="p40" begin="00:02:08.520" end="00:02:11.630" region="bottomCenter">en realidad es una elipse nosotros y la suma</p>
      <p xml:id="p41" begin="00:02:12.170" end="00:02:13.700" region="bottomCenter">es un enfoque</p>
      <p xml:id="p42" begin="00:02:14.070" end="00:02:14.710" region="bottomCenter">esta</p>
      <p xml:id="p43" begin="00:02:14.860" end="00:02:15.760" region="bottomCenter">fue el momento</p>
      <p xml:id="p44" begin="00:02:15.960" end="00:02:17.660" region="bottomCenter">cuando comenzó la ciencia</p>
      <p xml:id="p45" begin="00:02:18.240" end="00:02:20.000" region="bottomCenter">cuando la gente hacer mediciones</p>
      <p xml:id="p46" begin="00:02:20.130" end="00:02:23.220" region="bottomCenter">y estudiado cuidadosamente lo que significaba estas mediciones</p>
      <p xml:id="p47" begin="00:02:23.470" end="00:02:27.030" region="bottomCenter">y como saben en aquellos días antes de galileo</p>
      <p xml:id="p48" begin="00:02:27.170" end="00:02:31.360" region="bottomCenter">copérnico pensaban que la suma se movía alrededor de la tierra</p>
      <p xml:id="p49" begin="00:02:31.570" end="00:02:33.820" region="bottomCenter">de hecho el sentido común sugiere como</p>
      <p xml:id="p50" begin="00:02:34.160" end="00:02:35.740" region="bottomCenter">en la mañana aquí</p>
      <p xml:id="p51" begin="00:02:35.850" end="00:02:40.610" region="bottomCenter">en la tarde como en el sentido común sugiere que la suma va alrededor de la tierra</p>
      <p xml:id="p52" begin="00:02:40.880" end="00:02:43.290" region="bottomCenter">pero commonsense puede ser engañosa</p>
      <p xml:id="p53" begin="00:02:44.490" end="00:02:46.420" region="bottomCenter">la propia ciencia commonsense</p>
      <p xml:id="p54" begin="00:02:46.630" end="00:02:54.290" region="bottomCenter">parece detrás de los detalles de examinar más profundamente en las paredes parece estar ocurriendo intenta encontrar algunas pruebas ahora</p>
      <p xml:id="p55" begin="00:02:54.690" end="00:02:58.370" region="bottomCenter">las evidencias aquí indicó que en realidad era tierra</p>
      <p xml:id="p56" begin="00:02:58.500" end="00:03:00.640" region="bottomCenter">que ronda algunas vueltas</p>
      <p xml:id="p57" begin="00:03:02.140" end="00:03:06.040" region="bottomCenter">y eso era gente conocida como christian hoy armas muy</p>
      <p xml:id="p58" begin="00:03:06.200" end="00:03:07.680" region="bottomCenter">famoso</p>
      <p xml:id="p59" begin="00:03:07.830" end="00:03:11.120" region="bottomCenter">científicos de hecho algunas personas dirían que fue el primer</p>
      <p xml:id="p60" begin="00:03:11.430" end="00:03:16.060" region="bottomCenter">científicos físicos alma y básicamente físico teórico</p>
      <p xml:id="p61" begin="00:03:16.520" end="00:03:18.480" region="bottomCenter">porque escribió la primera ecuación</p>
      <p xml:id="p62" begin="00:03:18.890" end="00:03:20.320" region="bottomCenter">y de hecho en un en</p>
      <p xml:id="p63" begin="00:03:20.480" end="00:03:22.130" region="bottomCenter">en holland en los países bajos</p>
      <p xml:id="p64" begin="00:03:22.290" end="00:03:23.550" region="bottomCenter">ponen pistolas de juguete</p>
      <p xml:id="p65" begin="00:03:24.290" end="00:03:25.080" region="bottomCenter">billetes</p>
      <p xml:id="p66" begin="00:03:25.230" end="00:03:29.950" region="bottomCenter">usted encontrará que en la mayoría de los países científicos sobre billetes de hecho</p>
      <p xml:id="p67" begin="00:03:30.200" end="00:03:31.970" region="bottomCenter">en gran bretaña tenemos faraday</p>
      <p xml:id="p68" begin="00:03:32.140" end="00:03:33.370" region="bottomCenter">y tenemos darwin</p>
      <p xml:id="p69" begin="00:03:33.700" end="00:03:39.130" region="bottomCenter">y sus aquí en los países bajos tenemos toy guns y si vas a ross figura austria</p>
      <p xml:id="p70" begin="00:03:39.350" end="00:03:40.470" region="bottomCenter">usted antes más duras</p>
      <p xml:id="p71" begin="00:03:40.590" end="00:03:44.680" region="bottomCenter">es curioso que en américa han políticos de billetes</p>
      <p xml:id="p72" begin="00:03:44.970" end="00:03:48.310" region="bottomCenter">sugiere algo diferente del resto del mundo</p>
      <p xml:id="p73" begin="00:03:48.570" end="00:03:49.310" region="bottomCenter">sin embargo</p>
      <p xml:id="p74" begin="00:03:49.490" end="00:03:50.480" region="bottomCenter">hoynes fue realmente</p>
      <p xml:id="p75" begin="00:03:50.710" end="00:03:55.690" region="bottomCenter">un físico y aquí están algunos de sus dibujos fue la primera persona a proponer la</p>
      <p xml:id="p76" begin="00:03:55.710" end="00:03:57.440" region="bottomCenter">ola teoría de luz</p>
      <p xml:id="p77" begin="00:03:57.740" end="00:04:03.940" region="bottomCenter">pero también sabía un montón de matemáticas y también comprendió y diferenciación</p>
      <p xml:id="p78" begin="00:04:04.380" end="00:04:09.830" region="bottomCenter">aquí están sus dibujos de las ondas de luz saliendo de una vela y</p>
      <p xml:id="p79" begin="00:04:09.840" end="00:04:12.570" region="bottomCenter">aquí están algunos de los dibujos de sus libros</p>
      <p xml:id="p80" begin="00:04:12.680" end="00:04:19.620" region="bottomCenter">y él lo que he entendido realmente tomó la primera pintura en un resorte ver</p>
      <p xml:id="p81" begin="00:04:19.650" end="00:04:21.180" region="bottomCenter">de ver n.w.o.b.h.m.</p>
      <p xml:id="p82" begin="00:04:21.390" end="00:04:22.640" region="bottomCenter">así que es realmente</p>
      <p xml:id="p83" begin="00:04:22.780" end="00:04:23.640" region="bottomCenter">el padre</p>
      <p xml:id="p84" begin="00:04:23.770" end="00:04:26.950" region="bottomCenter">de este reloj que gente paga mucho dinero defecto</p>
      <p xml:id="p85" begin="00:04:27.140" end="00:04:30.600" region="bottomCenter">en comparación con este fantástico que es un gran</p>
      <p xml:id="p86" begin="00:04:30.880" end="00:04:36.320" region="bottomCenter">tipo de realmente un increíble e tipo de culminación de tecnología</p>
      <p xml:id="p87" begin="00:04:36.490" end="00:04:38.700" region="bottomCenter">ya que hay 44</p>
      <p xml:id="p88" begin="00:04:38.810" end="00:04:41.170" region="bottomCenter">pero en realidad este uno más preciso que éste</p>
      <p xml:id="p89" begin="00:04:41.610" end="00:04:42.120" region="bottomCenter">ahora</p>
      <p xml:id="p90" begin="00:04:42.390" end="00:04:45.940" region="bottomCenter">hoynes sabía el centro de rollo pura fuerza de ley</p>
      <p xml:id="p91" begin="00:04:46.160" end="00:04:52.900" region="bottomCenter">y también nuevos o algo sobre satins mociones y darse cuenta de que saturno no podía ser sólido</p>
      <p xml:id="p92" begin="00:04:53.320" end="00:04:58.230" region="bottomCenter">así que es realmente uno de los primeros físicos teóricos si no el primero</p>
      <p xml:id="p93" begin="00:04:58.410" end="00:04:59.790" region="bottomCenter">y el entendió realmente</p>
      <p xml:id="p94" begin="00:04:59.920" end="00:05:01.470" region="bottomCenter">esta ecuación</p>
      <p xml:id="p95" begin="00:05:01.590" end="00:05:02.670" region="bottomCenter">en el cálculo</p>
      <p xml:id="p96" begin="00:05:03.280" end="00:05:04.090" region="bottomCenter">sin embargo</p>
      <p xml:id="p97" begin="00:05:04.720" end="00:05:05.890" region="bottomCenter">lo que sucedió entonces</p>
      <p xml:id="p98" begin="00:05:06.450" end="00:05:08.160" region="bottomCenter">fue que robert hook</p>
      <p xml:id="p99" begin="00:05:08.750" end="00:05:13.200" region="bottomCenter">que fue muy realmente un genio pero no muy buen matemático</p>
      <p xml:id="p100" begin="00:05:13.750" end="00:05:14.980" region="bottomCenter">escribió a newton</p>
      <p xml:id="p101" begin="00:05:15.540" end="00:05:15.820" region="bottomCenter">y</p>
      <p xml:id="p102" begin="00:05:16.080" end="00:05:20.250" region="bottomCenter">en la carta se decía usted cree que una ley cuadrados inversa</p>
      <p xml:id="p103" begin="00:05:20.380" end="00:05:21.380" region="bottomCenter">explicaría</p>
      <p xml:id="p104" begin="00:05:21.600" end="00:05:24.090" region="bottomCenter">los movimientos de los planetas en particular</p>
      <p xml:id="p105" begin="00:05:24.310" end="00:05:27.530" region="bottomCenter">el hecho de que las órbitas de marte fue una elipse</p>
      <p xml:id="p106" begin="00:05:27.710" end="00:05:29.530" region="bottomCenter">con algunos en su centro</p>
      <p xml:id="p107" begin="00:05:29.910" end="00:05:34.610" region="bottomCenter">ahora la ley cuadrados inversa es interesante se aplica a la luz</p>
      <p xml:id="p108" begin="00:05:34.940" end="00:05:38.180" region="bottomCenter">al alejarse de decir con la antorcha</p>
      <p xml:id="p109" begin="00:05:38.380" end="00:05:41.490" region="bottomCenter">la plaza inversa analogia la intensidad</p>

      <p xml:id="p112" begin="00:05:49.670" end="00:05:50.560" region="bottomCenter">ahora puedes</p>
      <p xml:id="p113" begin="00:05:50.970" end="00:05:54.400" region="bottomCenter">entonces realmente resolver estos problemas como la mayoría de nosotros sabemos</p>
      <p xml:id="p114" begin="00:05:54.630" end="00:05:57.210" region="bottomCenter">y él y utilizar tales cosas como</p>
      <p xml:id="p115" begin="00:05:57.580" end="00:05:59.630" region="bottomCenter">y la integración de cálculo</p>
      <p xml:id="p116" begin="00:06:00.060" end="00:06:02.530" region="bottomCenter">pero veamos su integración esto es de</p>

      <p xml:id="p119" begin="00:06:04.970" end="00:06:07.480" region="bottomCenter">y lo que vemos es como una curva</p>
      <p xml:id="p120" begin="00:06:07.820" end="00:06:09.330" region="bottomCenter">y quiere saber</p>
