Section 2.2
Applet about the simple pendulum, created by Prof. Wolfgang Bauer.
Section 2.3
Amorphous metals are “futuristic alloys” that can be molded at less than 100 C. As detailed in this Physical Review Focus article summarizing research from 2005, they can be stress hardened to change their mechanical properties.	This image shows how the amorphous metal can be molded at temperatures of only 100 C. Reprinted figure with permission from B. Zhang, D. Q. Zhao, M. X. Pan, W. H. Wang, and A. L. Greer, Phys. Rev.

Section 2.4
Video lecture (click on play button) with demos about buildings and earthquakes, by Dr. Robert Butler.
Section 2.5
Animation by David M. Harrison showing the isomorphism between a torsional oscillator and a mass on a spring.
In 2005, Anatoly Mal’shukov and his co-authors showed that it should be possible to detect the spin of conduction electrons by the resulting torsion on a nanoscale bridge, as summarized in this Physical Review Focus article.
Section 2.6
Electrons have wave properties, and therefore show interference effects. Electrons flowing through a conductor scatter off impurities and other crystal defects, and these scattering events change the interference conditions, resulting in small changes in the electrical resistance. In research from 2004, Dr. Hiroshi Yamaguchi and his co-authors showed that vibrations of a microscale cantilever cause detectable changes in the electron interference, as summarized in this Physical Review Focus article.	The tiny cantilever used by Yamaguchi and co-authors. Reprinted figure with permission from H. Yamaguchi, Y. Tokura, S. Miyashia, and Y. Hirayama, Phys. Rev. Lett. 93, 036603 (2004).
