Great scientists
Warming up
Words and expressions
What do you know about great scientists? Try this quiz and find out who knows the most.
1. Which scientist discovered that objects in water are lifted up by a force that helps them float?
Archimedes
Archimedes, Ancient Greek (287-
212 BC), a mathematician. He
found that if you put an object into
water the water pushes the object
up. It rises and partly floats. The
force of the water pushing it up is
the same as the weight of the object.
2. Who wrote a book explaining how animals and plants developed as the environment changed?
Charles Darwin
Charles Darwin, Britain (1808 -- 1882)
The Origin of Species was published in 1859. It explained how plants and animals had changed over time to fit in with a changing environment. At the time it was published it was very controversial. Many people believed the Bible when it said that the God made the first two people
(Adam and Eve) and that all other people came from these two. Darwin’s book showed that people had developed from apes instead. So this caused a lot of argument between religious and scientific people. However Darwin’s idea became very influential and is still accepted today.
3. Who invented the first steam engine?
Thomas Newcomen
Thomas Newcomen, British (1663--1729) He improved the first steam pump built by Thomas Savery in 1698 and turned it into a steam engine for taking water out of mines in 1712. James Watt improved it still further in the 1770s turning it into the first modern steam engine used on the railways.
4. Who used peas to show how physical characteristics are passed from parents to their children?
Gregor Mendel
Gregor Mendel, Czech (1822- 1884)
He grew pea plants and developed
ideas on heredity(遗传学) and
inherited (继承,承传) characteristics.
He concentrated on cross-fertilizing
(施肥) pea plants and analyzing the
results.
5. Who discovered radium?
Marie Curie
the power of radium
Marie Curie, Polish and French (1867-
-1934) In 1898 she discovered radium.
She received two Nobel prizes, one
(with Pierre Curie ) for physics (1903)
and one for chemistry (1911). She was
the first woman to receive a Nobel
prize and the first woman to teach at
the Sorbonne (巴黎大学).
6. Who invented the way of giving electricity to everybody in large cities?
Thomas Edison
light bulb
phonograph
motion pictures
Thomas Edison, American (1847- 1931)
He was already an inventor of other
electrical devices (phonograph,
electric light bulb) when in 1882 he
designed a system for providing New
York with electricity from a central
power station. This was a tremendous
achievement, which had previously been
thought impossible.
7. Who was the painter that studied dead bodies to improve his painting of people?
Leonardo da Vinci
the Last Supper
Mona Lisa
Leonardo da Vinci, Italian (1452- 1519) He was a famous artist whose skill for showing human skin tones made his paintings seem to come alive. He used to study dead people in order to make his paintings as accurate as possible.
8. Who invented a lamp to keep miners safe underground?
Sir Humphry Davy
the Safety Lamp
Sir Humphry Davy, British (1778- 1829) He did research into different gases and discovered the medicinal value of nitrous (麻醉) oxide(氧化物) (or laughing gas) as an anaesthetic(麻醉剂). In 1815 he developed a safety lamp for miners. The safty helmet made working underground very much safer.
9. Who invented the earliest instrument to tell people where earthquakes happened?
Zhang Heng
Zhang Heng, Chinese (78- 139) He invented the first seismograph to indicate in the direction of an earthquake. It was in the shape of a cylinder with eight dragonheads round the top, each with a ball in its mouth. Around the bottom were eight frogs directly under a dragon’s head. When an earthquake occurred, a ball fell out of the dragon’s mouth, making a noise.
10. Who put forward a theory about black holes?
Stephen Hawking
Stephen Hawking, British (1942--) He has worked in astronomy and studied black holes in space. He has shown that black holes do not only absorb everything around them but, from time to time, throw out matter as well. This may mark the beginning of new galaxies. This is an advance on the old theory which said that black holes “eat” everything they come across.
