Chapter 1 introduces the field of structural dynamics with a detailed discussion of Newton's Laws of motion, starting with Newton's own words from The Principia. Each Law is discussed in detail using Newton's definitions of mass, inertial mass, inertia, force, centripetal force, inertial referen...
Let us help you review the topics you're learning about in class or study for a test with this middle school physical science course. Watch our short video lessons on the topics of chemistry, physics and space science, and then test your understanding with the quizzes and chapter tests. ...
Polycarbonates constitute an important class of polymers because of their remarkable impact strength. Bisphenol A polycarbonate (PC) is typical and has the repeat unit (2). 1H, 2H and 13C NMR studies clearly identify 180° aromatic ring flips about the C2 axis as the dominant motion in PC.91...
In 2004, physicists reported something remarkable: they had isolated ultrathin films of carbon atoms using sticky tape alone, and found that the films had astounding properties. The finding would forever change condensed-matter physics. Pablo Jarillo-Herrero ...
CallItAsItIs, as a professor for an in-person class, I do not respond well when a student stands up and shouts “Wrong!” (@760), disrupts the class, and then repeats his misunderstanding. In person, that student would be dismissed. Let me know, with some respect, if you have any ...
Over 500 scientific research institutes at home and abroad have participated in these projects, achieving important results in space life science, space medicine, space material science, and microgravity fluid physics with more than 280 papers published in international first-class journals, Lin said. ...
Recently, accelerations in SLR and in ice sheet mass losses have been detected, which is what you’d expect to happen when the globe warms, based on our understanding of the previous history of the Earth and our understanding of the physics of climate.Support for above: https://www.nasa....
This study used structural topic models (STMs) to analyze physics pre-service teachers’ conceptual understanding of scientific literacy. Participants included 126 physics pre-service teachers studying at Shandong Normal University in China. First, we used an open-ended questionnaire to collect the data...
