Facts of the compass

• Older roses-of-winds didn’t have sides of the world but the names of the 
• winds. There were two systems: Classical 12-wind system and Mediterranean 8-wind system.
• Magnetic compassdoes not point to a geographic pole, but to the magnetic pole.
• During the World War II, compasses were smuggled to the prisoners of war in German camps in the form of buttons and razor blades to help prisoners escape.
• The first needle of an iron needle compass from China was in a shape of a tadpole.
• When the Chinese started using a compass for navigation instead for divination, the typical navigational compass was in the form of a magnetic needle floating in a bowl of water.
• 5 facts of de inventor 
• Fact: Magnetite minerals and water – Most of the early Chinese compasses were made of magnetite minerals that would be bolted like a lace. On this magnetic float, placed in the water, the Earth’s magnetic field would work, so it would always be in the north-south direction.
  Fact: Use of magnetite – Needle of the compass was magnetized by rubbing the magnetite, blue-brown ore that came from China and Bengal.
  Fact: Origination of name – According to the legend, the word “magnet” derives from the name of the city Magnesia in Asia, there was a magnetite ore site in ancient times. According to another legend, the word originated from the name of shepard Magnus from Crete, who had iron shoes and once stopped on a stone made of magnetic ore.
  Fact: Useful improvement in Europe – Around 1300 the maritime compass was already widely used in southern Europe, Scandinavia and Iceland. But at this time the compass got useful improvement – it is placed in a cardanic hinge (two axes connected to the ring brass, allowing it to remain permanently in the horizontal position regardless of the swing of the ship).
  Fact: Wind rose – One more important improvement is the introduction of “wind rose”, that is, round tiles with sides of the world and a circle divided into 360 degrees. The “wind rose” would rotate until its northern direction would cling to the north end of the magnetic needle. After that, it was possible to read the ship course correctly.

Technological breakthroughs of history/ compass

What?

1. 1. 

   An instrument containing a magnetized pointer which shows the direction of magnetic north and bearings from it.
2. 2. 

   An instrument for drawing circles and arcs and measuring distances between points, consisting of two arms linked by a movable joint, one arm ending in a point and the other usually carrying a pencil or pen.

Why?
The magnetic compass was an important advance in navigation because it allowed mariners to determine their direction even if clouds obscured their usual astronomical cues such as the North Star. It uses a magnetic needle that can turn freely so that it always points to the north pole of the Earth's magnetic field


Who?
Magnetic field of the Earth and point Magnetic North-South. The First compass was invented in China during the Han Dynasty between the 2nd century BC and 1st century AD

Where?
In China by the military for navigational orienteering by 1040–44, and was used for maritime navigation by 1111 to 1117.

How?
To use a compass like this, you first figure out which direction is north. You let the needle settle then rotate the compass card so the needle lines up with the north-south axis and the end of the needle colored red, marked with an arrow, or printed 'N' points north.

When?
The magnetic compass was not, at first, used for navigation, but for geomancy and fortune-telling by the Chinese.

Technological Breakthroughs of History/ Light Bulb/ R.A

• 1 Technological Breakthrough

• 6 Questions to be answered 

• Images/ Pics 

_WHO?: Thomas Edison

_WHAT?: Light Bulb

_WHEN?: 1879 first working Lightbulb

_WHERE?: New Jersey

_WHY?: Because he thought that it would fix the darkness problem at night.

_WHAT?: The incandescent light bulb turns electricity into light bye sending the electric current through a thin wire called a filament. The resistance of the filament heats the bulb up. Eventually the filament gets so hot it glows.
