Vibrational control

Egyptian researcher Haitham Taha, an assistant professor at the University of California and the author of the research paper, revealed the mystery of insect flight .aa

Insects owe much of their extraordinary evolutionary success to flight. Flying insects are better able to escape predators, locate food sources, and colonize new environments in contrast with their flightless ancestors. Due to their survival and development, which is so decisively decided by the flight results, it is hardly surprising that insects are among the most persuasive examples of adaptions in nature, in their visual, physiological, behavioral, and biomechanical characteristics. In consequence, insects give biologists a variety of useful examples, both to explain the relationships between structural functions and evolutionary limitations in organism design .aa

In biology and engineering thinking, insects are unstable when flying. However, current methods based on the direct medium do not fully capture the dynamic and stability characteristics of insect flight. Here, we discover the method used by flying insects, which is vibrational stabilization (vibrating their wings). It was explained by researcher Haitham Taha using a type of calculus: the chronological calculus. This finding is especially useful to biologists because the mechanism for stabilizing vibration can be exploited by many organisms .aa

The researcher also explained that all studies during the past years said that insects' flight is unstable and that they are constantly correcting the way the wing flaps in order to maintain their balance, and this requires complex calculations that must be present in the insect's brain, such as (GPS) .aa

The Egyptian researcher discovered a phenomenon that occurs to the balance of the insect while flying, which is "stabilization by vibration," meaning that if there is an unstable system that has a vibration at high speed, it acquires stability automatically without the need for GPS, which indicates that the insect's flap makes its body vibrate a lot and gives it stability .aa

In so doing, the Egyptian researcher Haitham Taha helped biologists research and innovate in this theory . aa
