DOI: 10.1088/1361-6404/ac172f
Abstract: Traditional stilts have been known in many countries in Asia and Africa and are generally used as toys. The design is very simple, but their use is very difficult. Performers have to train intensively to… read more here.

DOI: 10.1088/1361-6552/ac015c
Abstract: This paper demonstrates the use of a smartphone’s sensors in recording experimental data for investigating the large angle of a physical pendulum. The smartphone (iPhone 5s) was attached to a beam to record simultaneously both… read more here.
