Query: Ideals and Virtual Realities   A main step for world progress is to keep sharing ever-present Ideals for
science and education within today Virtual Realities. On-line education is
transforming human society to new levels in the way people teach and learn
during the ongoing SARS-CoV-2 pandemic. There is an increasing interest in
having more and more reliable, fast and simple apps to communicate and also to
record, assemble and distribute videos and lectures in the fields of Physics &
Maths still using traditional didactic methods. We describe here how to
accurately reproduce chalkboard classes for the popular YouTube video platform
using OpenEyA-YT. The audience can thus be expanded over continents to help
mitigate the effects of physical isolation.
