Just one piece from the Great Minds puzzle range! Will you be able to master this challenging set of wooden brainteasers? Aim: Separate the pieces, then see if you can rebuild the comet and the globe. Galileo’s Globe Italian scientist and astronomer. As well as the telescope, Galileo also developed the compass and the thermometer. He claimed that the Earth was not the centre of the Universe but that the planets, including Earth, orbited around the Sun, a controversial theory at the time! By watching a lamp swinging in a cathedral he made discoveries about the perpetual motion of a pendulum. He worked out that a cannonball fired from a cannon follows a special kind of curve called a parabula. His fabled experiment at the top of the Leaning Tower of Pisa demonstrated that objects of different weights will fall at the same speed. Halley’s Comet English astronomer and mathematician. As a young man, Edmund Halley excelled at mathematics, physics and astronomy, becoming the youngest member of the Royal Society at the age of 22. He is best known for calculating the orbit of the comet, now known as Halley’s Comet, only visible from Earth every 75-76 years. Its appearance had been recorded since 240 BC, it even features in the Bayeux Tapestry produced shortly after 1066. After seeing the comet in 1682, Halley realised it was the same comet that had been sited in 1456, 1531 and 1607. He predicted its return in 1758. It duly appeared on Christmas Day of that year. Sadly, Halley did not live to see his prediction fulfilled.
