The Lightsabers Of Star Wars
The fictional Lightsabers are technically laser beams, which have diverse usage at low watts, like scanning UPCs, mapping buildings, remote sensing of the ozone layer or carbon dioxide levels.
Industrial lasers can burn and cut as well but have bulky power supplies, unsuitable for a lightsaber fight.

The Hit Effect
Lightsabers are shown to strike surfaces just like a real sword, but they are made of photons with no mass, so hitting something physical, or producing a sound when striking an object is only in the fictional realm
Current technology can create a high-powered laser beam in the shape of a glowing rod made of plasma but it still would not have the practical usage, namely, the sword fights shown in the Star Wars series.

Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
