The topic: electric field.
Surprisingly, a more in-depth analysis of the articles in Figure 3 suggests that, not only did all of them appear in the same journal (Physical Review E), but indeed they are all concerned with the same topic (electric discharges) and share a relatively large fraction of PACS codes (05.45.-a 05.45.-ac).
More on the electric field as the topic can be found in Appendix 2. Briefly, we wanted an abstract topic that would include motion and effects that are not seen with the naked eye, because mixed and virtual realities are well-positioned to make the unseen seen.
The questions that pop up when electric bicycles are the topic of discussion usually revolve around their feasibility as a realistic mode of transportation.
The second dataset was on political candidates for a presidential election, while the third and final dataset was on the topic of electric vehicles.
Electric mobility is a topic of intense discussions in academia and industry since the stability of future energy supply as well as the associated environmental consequences are uncertain.
The air felt charged with an electric optimism, and no topic was off-limits, from atheism to the erotic.
The theme of the event is 'The New Beginning,' and we'll be looking at a host of topics from electric vehicles and live-streaming to co-working, e-commerce, artificial intelligence, toys and even emojis 😁.
Introductory physics 2, taught by a female faculty member, is also a lecture-based course, and focuses on conceptual understanding of topics including electric charge; electric field; potential and current; magnetic field; capacitance, resistance, and inductance; circuits; electromagnetic waves; and optics.
The topic of the electric field was chosen because it can be a challenge to embody highly abstract content.
