IKEA is a retailer selling low-price furniture, home accessories, bathrooms and kitchens around the world.

IKEA was founded in 1943 by Ingvar Kamprad in Sweden. The name IKEA comes from the initials of the founder's name (Ingvar Kamprad), farm where he grew up (Elmtaryd) and his home village (Agunnaryd).

Founded in 1943, IKEA today has over 235 stores in more than 30 countries and more than 110,000 co-workers (this is the exact word they use in egalitarian IKEA).

A survey in 2007 ranked 80-year old Ingvar Kamprad the second most admired man in Sweden.

Macadamia is the world’s most expensive nut. Native to eastern Australia and Indonesian Sulawesi, this nut is extremely hard to crack (it requires pressure of about 300 psi or 2000 kPa). Due to rather complicated production, the nut sells for 30-40 dollars per kilo on the international markets.

Spice Saffron, which is the stamens of the saffron crocus, has built a reputation for being more expensive than gold. Its high price stems from the labor input: only about 6 pounds (2,7 kilo) of saffron can be produced from each acre (0,4 hectare) of land, so the price per kilo goes as high as $6000.

The metric system is a widely adopted decimalized system of measurement that derives from decimal numeral system being the consequence of us having 10 digits (fingers and thumbs).

Before the metric system became a standard in Europe, the local laws on measures were set by trade guilds on a city-by-city basis. In Switzerland, the survey of 1838 discovered that the foot had 37 different regional variations.

At the end of 18th century Louis XVI of France commissioned the group of scientists to develop a unified, practical and simple system of measurement to replace the disparate systems used back then. The scientists come up with the metric system that was derived from the properties of natural objects, i.e. the size of the Earth, the density of water, and relations between these. For instance, 1 meter was originally defined as 1/40,000,000th of the polar circumference of the Earth.

There are about 20,000 known species of bee, in 9 recognized families.

Colonies of honey bees are long-lasting and may live for many years. The population of a healthy colony in mid-summer can average between 40,000 and 80,000 bees.

The male bees – drones – do not have stingers, and do not forage for nectar or pollen. Their only role is to fertilize a new queen. They die immediately after mating as this process requires from them a fatally convulsive effort. The drones are turned outside in autumn to die since their reproductive role is over.

Queen bee is an adult, fully sexually developed female, the mother of all the bees in the hive. The queens are developed from larvae selected by worker bees and fed only on royal jelly, a substance secreted by the workers that is high in protein, in order to become sexually mature. Adult queens are overweight and unable to fly. The average lifespan of the queen is three to four years.
