Communities Drones

After a long deliberation, the inventor has decided to use the time separation principle and has chosen to deliver sandwiches exactly when they are needed by means of helicopter drones. As a temporary measure, she will first use the communication drones that are already in use to carry confidential messages among the support team members. Later, special stealth helicopter drones will be ordered (and invented first), which be invisible to other teams and which will fly silently. [Pg.304]

It cannot be denied that women have contributed their fair share of original communications. Indeed, in proportion to their numbers they have shown themselves to be among the most active and successful of investigators. The society consents to publish their work which redounds to its credit. Why, then, should the drones who never have done, and never will do, a stroke of original work in their lives be preferred to them simply because they wear a distinctive dress and are privileged to grow a moustache ... [Pg.70]

There are about 20,000 species of bees, but it is only honey bees that make honey and wax in large amounts. Honey bees (workers, drones, and queens) are fascinating creatures they have their own social system and complex behavioral patterns, which we are only just beginning to understand. Working with a community of bees offers an absorbing and unique insight into the annual cycles and workings of the natural world. [Pg.260]

Honeybees are around three-quarters of an inch long, and most of them are workers (females). The males are called drones and are slightly larger than the females. Drones have a unique and specific function in this community to mate with the queen. Females are responsible for all the work inside and outside the hive. Among other activities, this work involves (indirectly) pollination and (directly) honeycomb construction. As outlined below, pollination is very important and crucial for the survival of humanity in addition, understanding the logic behind the construction of honeycombs can help us improve and optimize the design and construction of various pieces of equipment and structures. [Pg.50]

Acoustics ai uably originated with human communication and music. The caves in which the prehistoric Cro-Magnons displayed their most elaborate paintings have resonances easily excited by the human voice, and stalactites emit musical tones when struck or rubbed with a stick. Paleolithic societies constructed flutes of bird bone, used animal horns to produce drones, and employed ratdes and scrapers to provide rhythm. [Pg.2]
