> Projectiles are flying buckets. Appreciate the response. I dissagree, respectfully, but I guess it really depends on how the author defines the term "bucket", which isn't explicitly provided in the article. By common definition (1) and also based on the context used in the article, a "bucket" is a type of discrete vessel (container) and is discrete from the contents (payload or 'thing') it carries. Conversely, a projectile has no container. Additionally, a projectile doesn't necessarily need a discrete size. Atmospheric moisture or electromagnetic energy are examples of things that we consume which move through space in a continuous stream, but these things are not necessarily confined to a vessel or pipe. To more clearly differntiate the three: Bucket System == Container + Payload + Energy imparted on the container & payload. Pipe System == Container (i.e. pipe or guide) + Payload + Energy imparted on the payload alone. Projectile System == Payload + Energy imparted on the Payload alone. Clearly we rely on the atmosphere to transport water in the form of clouds, and we can rely on this mode of transport to deliver drinking/farm water even though clouds are not contained in a transport vessel, because humans have learned to leverage weather patterns. We harvest drinking water (thing) on land from the atmospheric pool of moisture originating from oceans. Similarly, we harvest radio signals (things) from antenna transmission in space (directed or distributed), but these transmissions are not contained and transported in any vessel. RF transmission (thing) along a waveguide (container) would fall under the pipe system definition. In wartime, propaganda leaflets (things) dropped from aircraft would fall under the projectile definition. Solar panels collect photons (things) projected from a light source to power electronics. All of these examples are things that are transported (naturally or synthetically) without the use of any container. Under the definition you provided, I could say that a slug of water in a pipe system is a "discrete bundle", so it's unclear where are we trying to draw the line or what the core significance is with this definition of "bucket". All that being said, I have no idea if this ultra-precise delineation between modes in which humans transport things is really germane to the original article. Maybe all that's needed is to differentiate between discrete and continuous transport modes. I was just stating that, for me, the ambiguity in this particular declarative statement prevented me from investing more time to finish reading what I felt began as an interesting line of thought. 1. https://www.merriam-webster.com/dictionary/bucket https://www.merriam-webster.com/dictionary/bucket
