BIONICS QUIZ

WHAT IS BIONICS?
Bionics is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology.
1.After a hunting trip in the Alps in 1941, Swiss engineer George de Mestral’s dog was covered in burdock burrs. Mestral put one under his microscope and discovered a simple design of hooks that nimbly attached to fur and socks.
After years of experimentation, he invented ----------- and earned U.S. Patent 2,717,437 in October 1952.this is used in shoes and for fastening space suits.
2.High-speed trains can literally cause headaches. That's why Japan limits their acceptable noise-pollution level, which can be particularly high when the trains emerge from tunnels. As they drive through, air pressure builds up in waves and, when the nose emerges, can produce a shotgun-like thunderclap heard for a quarter mile.
Eiji Nakatsu, a bird-watching engineer at the Japanese rail company JR-West, in the 1990s took inspiration from the kingfisher, a fish-eating fowl that creates barely a ripple when it darts into water in search of a meal. The train’s redesigned nose — a 50-foot-long steel kingfisher beak — didn't just solve the noise problem; it reduced power use and enabled faster speeds.what do the Japanese call their bullet trains( the same thing they call a kingfisher in their language ?
3.The whole body Speedo swimsuit is banned in international swimming competitions . the surface design of this swimsuit is inspired by which sea creature  ?
