Sunflowers, one
or many
Take
a close look at a sunflower in full bloom. What do you
see? Can you see the small petal-like rays on the edges of the
flowers? These are actually tiny imperfect flowers. And what
makes them imperfect is the fact that they lack stamens – the
pollen producing part of a flower. The disk in the middle is
made up of small flowers yellow, brown or purple in colour.
The sunflower plant is very useful. Its flowers yield a yellow
dye, its seeds are used for producing oil and its leaves are
used as fodder for animals. |

Taxed If You Have A
Beard
Peter
the Great who was the Emperor of Russia during the period 1682 -
1725 was responsible for replacing the traditional Russian
calendar with the Julian calendar. He was so influenced by
Western European culture that in his zeal to convert Russians he
imposed a tax on men who persisted in growing beards that gave
them a very Russian look! So taken in was he by European culture
that he founded a new city, St. Petersburg, and moved the
Russian capital there so that he could be closer to Europe. |

Mates lured by scent
One would imagine that
given the beautiful colours of their wings, female butterflies
would be fluttering them to attract the male. But no. Female
butterflies have a store of perfume in their bodies. This store
weighs about one-ten thousandth of a milligram. The female uses
just a tiny fraction of this and yet, even from a distance of 10
km the male manages to catch the scent and makes a beeline for
her! |

Space Station
The International Space Station is shown in
an image taken by the STS-110 crew members on board the Space
Shuttle Atlantis following the undocking of the two spacecraft
some 247 statute miles above the North Atlantic. The shuttle
astronauts left the space station 27,000 pounds heavier with the
addition of a 44-foot-long aluminium girder, the first piece of
a framework that will ultimately extend 356 feet by 2004. |

The biggest spewing
of ash
One of the best ways to tell the size of an
eruption is to work out how much ash it blew out. On this basis,
the biggest volcanic eruption in history was that of Tambora in
Indonesia in 1815, which blasted out some 80 cubic kilometre of
ash into the air! The second biggest eruption also happened in
Indonesia, at Krakatau. But at 18 cubic kilometre, Krakatau
looks tame compared to Tambora. |

Crocodile Tactics
You might find this tough to
believe, but freshwater crocodiles are harmless to man. They eat
only fish and small aquatic animals. The problem though is
spotting the difference between a fresh water crocodile and an
estuarine (salt water) one. You have to be an expert to tell one
from the other. The salt water species is the world’s largest
living reptile — it can grow to over 6 metre in length — and
also the most dangerous. Estuarine crocodiles kill hundreds of
people each year. They submerge themselves in water with only
their eyes and nostrils showing, making it very difficult for
someone to spot their presence. They attack unsuspecting prey
suddenly, drag the victim by tightly holding on to a limb
between their jaws and then kill it by twisting the limb so that
the prey twists and rolls over into the water several times
before drowning. The crocodile’s tail is very powerful, and is
often the weapon with which it hits the prey so that the victim
loses balance and falls into the water. Sounds gory, doesn’t it?
Unless you’re very sure that the reptile in the water is a fresh
water one, you shouldn’t be going in for a dip. |
