Faroe Islands

The Faroe lslands is a North Atlantic archipelago located 320 kilometres (200 mi) north-northwest of Scotland, and about halfway between Norway and lceland. It is an autonomous territory within the Kingdom of Denmark. The islands have a total area of about 1,400 square kilometres (540 sq mi) with a population of 51,783 as of June 2019.

In Faroe Island, it rains 300 days during the year, so the settlers introduced the grass roofs as it provided protection from the sobbing rain and thermal insulation. The load of a sod roof is approximately 250 kg per m2. In winter the total load may well increase to 400 or 500 kg per m2 because of snow. Sod is also a reasonably efficient insulator in a cold climate. The birch bark underneath ensures that the roof will be waterproof.

The term 'sod roof is somewhat misleading, as the active, water-tight element of the roof is birch bark. The main purpose of the sod is to hold the birch bark in place. The roof might just as well have been called a "birch bark roof", but its grassy outward appearance is the reason for its name in Scandinavian languages: Norwegian and Swedish torvtak, Icelandic torfpak.

Why planes don't fly in a straight line on a map?

Have you ever been on a long-haul flight and wondered why your aircraft is takinga curved route instead of flying in a straight Iine when you look at the inflight map? This is particularly noticeable when flying between Europe and the U.S. when aircraft will fly over Greenland and Northern Canada rather than just simply flying from point A to B as it would visually appear on a map. The reason for this is down to simple mathematics and physics. The circumference of the Earth is lot further around the equator than it is at higher or lower latitudes towards the poles of the earth, such is the spherical shape of our planet.

Flying around the smaller circumference of the Earth is called the "Great Circle Route" and also very noticeable for flights from the U.S. to Asia that will fly far above Alaska and Siberia rather than wha would appear to be a straight line. If you think about drawing a line around a globe in the middle where it is widest, versus towards the North or South poles, the differentiation of distance begins to become apparent, and it not only saves a huge amount of time but also fuel. Because the Earth revolves on its axis, this forces the equator to "bulge out" and be wider. Despite what some theories suggest, the Earth is not flat, and so curvature becomes an incredibly importan factor in routes aircraft take. Similar to the Earth itself, aircraft, therefore, take flight routes that also appear to be a curved line, tracing the Earth's shape.

This is the largest digging machine (or trencher or rotating shovel) in the world.

It was built by TAKRAF and is shown here crossing a road in Germany on the way to its destination, an open air coal mine. Although at the mine the treads are unnecessary, it was cheaper to make the machine self-propelled than to try and move it with conventional hauling equipment Bagger 293 is 96 metres (314.9 feet) tall (Guinness World Record for highest terrestrial vehicle, shared with Bagger 288). It is 225 metres (738.2 feet) long (same as Bagger 287), weighs 14,200 tonnes (31.3 million pounds), and requires five people to operate. It is powered by an external power source providing 16.56 megawatts. The bucket-wheel itself is over 21.3 metres (69.9 feet) in diameter with 18 buckets, each of which can hold over 15 cubic metres (529.7 cubic feet) of material. It can move 240,000 m3 or 218,880 tonnes of soil per day (the same as Bagger 288).

Children living in Siberia getting UV light exposure during the long dark winter months.

Make-believe summer lasts for a minute or two as kindergarten children in SUN-less Lovozero bathe in ultraviolet light. Brief exposure to UC radiation provides the children with vitamin D, normally supplied by sunlight. The "sunshine vitamin" strengthens young bones.
