Streszczenie:<\/em><\/strong>
Mechaniczny zegar z wahad\u0142em przez stulecia przez stulecia stanowi\u0142 jeden z podstawowych sposob\u00f3w pomiaru czasu. Jego centraln\u0105 cz\u0119\u015bci\u0105 jest wahad\u0142o t\u0142umione, utrzymywane w ruchu przez mechanizm zegarowy. Mechanizm ten dostarcza energi\u0119 do wahad\u0142a i jest jednocze\u015bnie przez to wahad\u0142o regulowany; to sprz\u0119\u017cenie zwrotne sprawia, \u017ce dynamika uk\u0142adu jest nieliniowa i cz\u0119sto chaotyczna. Wi\u0119kszo\u015b\u0107 pr\u00f3b poprawy precyzji pomiaru czasu opiera\u0142a si\u0119 o redukcj\u0119 wp\u0142ywu efekt\u00f3w nieliniowych poprzez zminimalizowanie oddzia\u0142ywania mi\u0119dzy wahad\u0142em a mechanizmem – tak, by by\u0142o dobrym przybli\u017ceniem swobodnego wahad\u0142a matematycznego. Zupe\u0142nie odmienne podej\u015bcie zaproponowa\u0142 w 1722 r. John Harrison. Dzi\u0119ki analizie numerycznej mo\u017cna zbada\u0107 dynamik\u0119 jego konstrukcji i wykaza\u0107, \u017ce mo\u017cliwy jest b\u0142\u0105d wskaza\u0144 na poziomie kilku sekund rocznie, co jest warto\u015bci\u0105 nieosi\u0105galn\u0105 dla innych typ\u00f3w zegar\u00f3w mechanicznych.<\/p>\n\n\n\n

Dr in\u017c. David Ziemkiewicz pracuje w Instytucie Matematyki i Fizyki Politechniki Bydgoskiej. W ramach grupy fotoniki i in\u017cynierii kwantowej zajmuje si\u0119 badaniem ekscyton\u00f3w rydbergowskich i propagacji plazmon\u00f3w powierzchniowych. Jest autorem ponad 30 artyku\u0142\u00f3w naukowych na temat plazmoniki, metamateria\u0142\u00f3w o ujemnym wsp\u00f3\u0142czynniku za\u0142amania, ekscyton\u00f3w rydbergowskich, aerodynamiki skrzyde\u0142, fraktali i dynamiki zegar\u00f3w.<\/em><\/p>\n\n\n\n
