Three passions, simple but overwhelmingly strong, have governed my life; the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind.
—Bertrand Russell in What I Have Lived For
Have you ever thought about inventing something? Were you worried that your idea was too strange or unrealistic? Well, maybe you should think again.
Strange and unrealistic ideas never stopped Arthur Pedrick. Pedrick was a British inventor. Originally a government clerk, he spent his retirement in the 1960s and 1970s developing new and unusual ideas. Some of these ideas contradicted basic physics, but that didn’t stop Pedrick. One of his strangest ideas was a plan to connect Australia and Antarctica using large tubes, a distance of 10, 000 km! These tubes were designed to carry giant ice balls from Antarctica to Australia. The ice would then melt in the Australian desert, and the water would be used for irrigation. Another of Pedrick’s inventions was a radio-controlled golf ball. A golfer could change the speed and direction of the golf ball using small flaps attached to the ball, which could be controlled by computer chips. Using radio waves, golfers could also find their lost golf balls. Arthur Pedrick had thousands of bizarre ideas for inventions, most of which were never constructed.
Though many of Pedrick’s inventions were never developed, a lot of other strange ideas have been. In 1989, a company designed and sold a theft-prevention device for expensive cars. As part of this device, several tubes were attached to the bottom of a car. If someone tried to steal the car, super hot flames were emitted from the tubes and burned the car thief. Some people who were not thieves, however, were seriously injured by this device which they accidentally set off by walking past the car.
Other strange inventions include underwear for dogs and pens with drinkable ink. The underwear keeps dogs from making a mess when they go out for a walk. Also if you were ever thirsty during a test, a pen with drinkable ink would be very handy!
If you have an idea that seems a little out in left field, don’t let that stop you from trying it. You' 11 be in good company.

A collision between an aircraft and one or more birds is termed a bird-strike. Pilots sometimes record a birdstrike while at cruising altitudes, but most of them happen when an aircraft is relatively close to the ground, usually in proximity to an airport and during the circling, descent to land or take-off phases of a flight.
Birdstrikes may cause significant damage to an aircraft and/or, if the birds are ingested into a jet engine, a significant and sudden loss of power. If this were to happen during take-off or initial climb of a fully loaded passenger aircraft the results could be catastrophic—loss of the aircraft and the lives of those on board. Any bird is a potential hazard to aircraft and this is especially true as bird numbers and bird size increase.
Unfortunately airports themselves can be attractive to birds—rodents, insects and other small animals are a food source often found in flat grassed areas such as the runway strips. Even so, this problem can be reduced by careful habitat management or bird harassment techniques practised by airport maintenance and safety personnel.
Care needs to be taken by local authorities in deciding the location of rubbish tips, or when permitting other land uses that may be attractive to birds in this way. Of course these effects cannot always be anticipated with certainty since birds such as gulls have been recorded as travelling 50 ki-lometres or more from their roosting area to an attractive food source.
Local authority planning schemes often apply strict controls on developments such as abattoirs, cattle feed lots, grain handling, piggeries, canals and marina developments, fish farms, and suchlike. In most cases these uses will not be permitted without a full environmental study. That study should be required to deal with the question of likely bird hazards if the proposed location is in proximity to an airport.
In some instances it may be necessary to consider ways of managing a particular land use in order to reduce its attractiveness to birds, for example the adoption of land-fill measures at garbage tips, or enclosed rather than open-air activity. Specialist ornithological opinion may be necessary. In such cases it may not be possible to implement immediate changes in land use, but this should not inhibit the adoption of long-term measures which are designed to achieve this. Summary:
A collision between an aircraft and one or more birds is known as a bird strike. It usually happens when an aircraft is close【61】, and may result in significant damage of the aircraft or loss of the aircraft and【62】of passengers and crew if they occur during take-off or initial climb.
