Codes

 

Hello Everyone

image001

 

Last week Bill and Bob were learning about flags at school and l told them how flags could be used to send messages. This week by coincidence they started learning about signals and codes at Beaver Scouts.

 

They learnt about semaphore, which is sending messages across a distance using two flags held in different positions. Each position represents a letter of the alphabet.

 

Bill and Bob thought that it was all too difficult to remember it all. They concluded that it was much easier to use a mobile ’phone. smile1 (2)

 

When they set up camp in Auntie Alice’s garden they use their walky-talky set. One set in their tent and one in the kitchen which enables Auntie Alice to tell them when their tea is ready.

 

When they play at being secret agents, because they are twins, each calls himself Agent 003½. smile1 (2)

 

They then decided that they would make up their own secret code so that they could send each other secret messages that no one else could understand.

 

Here it is…

 

Each symbol represents a letter of the alphabet.

 

A  !                       J <                      S ∆

B  #                     K >                      T ∏

C  &                     L   ?                    U ∑

D  (                      M  [                     V √

E  )                       N  ]                     W ∞

F  *                      O ÷                      X ∫

G  +                     P  †                       Y ≠

H  0                    Q   ‡                      Z ◊

I  :                        R  •

 

Can you work out what these Bill and Bob secret messages say?

 

[))∏  [)  #)0:](   ∏0) #:&≠?)   ∆0)(∆   !∏   ∏0•))   ÷’&?÷&>   –   #:??

#) &!•)*∑?   0÷∞   ≠÷∑   &•÷∆∆   ∏0)   •÷!(∆   –   ∑]&?)   ∆![

 

You could use Bill and Bob’s secret code to send messages to your brothers and sisters and friends. Or you could make one up of your own!

Signal–flag training set used by sailors to help them learn signal codes

The little flags are made of wood 

 image033

The pattern and colours on each flag represents a number or letter and so spell out words when arranged in groups

 
image035

Signal flags were hoisted high up in the rigging of a ship so that using a telescope the signal flags could be seen by other ships from miles away 

 image037

A model of a shutter telegraph model (about 1795)

This way of sending coded messages was used to communicate between London and the coast from 1796 – a chain of huts was built on high ground and messages were sent from one hut to another down the chain by positioning the shutters in a certain way

It needed four men in each hut to keep watch with telescopes and operate the shutters using ropes – although the messages could travel so much more quickly than a messenger on a horse, the system did not work in fog or heavy rain

 
image039

A ship’s telegraph was used to communicate between the bridge where the captain stood and looked out to sea and the engine room – the handles on this machine would be moved and a bell would sound signals for the crew in the engine room

The captain would give orders regarding speed and direction and the engine room would signal back that they had carried out the order – you may have seen these in old movies

Today ships usually use internal telephones

 
image041

The electric telegraph revolutionized communication over long distances and lead to the development of Morse code in 1837

Morse code messages could be sent from ships using flashing lights – this hand held light from the 1950s had a trigger in order to switch the light on and off quickly so that the dots and dashes could be signalled between ships or across land

Messages can be sent in Morse code using pulses of electricity and there are still people today that use it to communicate with each other as a hobby

The children’s activity centre at the National Maritime Museum

Where you can have a go at sending your own Morse code messages 

 image048

The first mobile telephones were much larger than they are today

They were almost the size of a house brick

 
image050

Some messages can be conveyed in pictures – this lion represents England and the unicorn represents Scotland 

 image052

Of course you already know these and you will know what they mean in any country even if you can’t speak the language there

Flags represent countries or sometimes organizations

Flags can be seen at a distance

Of course when you create codes, it is really important to get your spelling right otherwise your message could be confused and difficult to understand.

HOW TO MAKE lNVlSlBLE lNK

 
Another way to send secret messages is by using invisible ink!

 
METHOD ONE

Write your message with a cotton bud or tooth pick using slightly diluted lemon juice or milk. In order for your message to be read, the person receiving it just has to heat the piece of paper up next to a light bulb.

*(Be careful – light bulbs get hotter than you think!)

 
METHOD TWO

Write your message in white crayon and expose it by just rubbing another colour crayon over it!
