Navigation

Navigation is according to the National Geographic the art and science of determining the position of a ship or plane or other vehicle and guiding it to a specific place. Consequently, navigation requires someone who can work out the vehicle location compared to other locations.

Some methods of navigation have been around for millennia such as the ancient mariners using landmarks or observing the movement of the sun and stars. Minoans who lived on Crete from 3000-1100 BC left records showing they used the stars to navigate.

At sea, mariners use a navigation method known as dead reckoning which uses the course and speed of a ship to determine its position. Piloting can also be used in narrow waterways by using geographical landmarks to determine a ship’s position.

Navigating on land whether on foot or in a vehicle involves the use of maps, reading the terrain, referring to a compass and landmarks such as hills or buildings to identify location. If you are in a town or city then maps that feature bus routes, train stations and underground stations are also accessed to provide information of location.

Celestial navigation or astronavigation involves the use of the sun, moon, stars, constellations and the horizon using an instrument such as a sextant to calculate position and location when travelling on the open sea which has no landmarks to aid navigation. A navigator needs to be aware of the different stars and constellations in the northern and southern hemispheres. For example, the Southern Cross constellation appears only in the southern hemisphere and the Plough constellation appears only in the northern hemisphere.

Other forms of navigation include the use of a satellite system called global positioning system or GPS. This system is owned and financed by the American government’s Department of Defence but anyone with a GPS receiver can use it. The GPS is a form of radio navigation and provides very accurate location and position information for the GPS receiver. This form of navigation can be used at sea or on land.

Navigation is not confined to travelling on land, sea or air. People navigate their way around their email inbox identifying which emails to answer, which to prioritise and which to ignore and/or delete. Indeed, people now have to navigate their way around websites of all descriptions whether in work or for personal use.

In fact, there are four types of website navigation. The first is the top menu which is the main website navigation bar usually at the head of the website page. The next navigation aid is the footer menu which may have a lot of information or just basic site information.

The third type is the side bar which is used in ecommerce and information heavy sites such as blogs. The sidebars can be on the left or the right of the screen page. The fourth type of website navigation is called breadcrumbs which are hierarchical that show how pages are nested within each other. Breadcrumbs are good for helping users find their way around within a website of specific interest to them such as online shopping websites.

Indeed, any organisation or business uses navigation to identify issues, plot course corrections and develop new ways of implementing services or products. Governments too, whether local or national, also use navigation tools to find out what voters are thinking regarding policies or voting intentions in a forthcoming election.

These methods can include focus groups, survey research using samples and populations, opinion polls, mail surveys, telephone surveys, interest groups or lobbying and protests such as marches to measure public opinion. From these methods policy documents, laws and manifesto declarations can be identified and implemented.

Which brings us to the present day and the current government is preparing to navigate its way around the ongoing unrest in Britain over issues such as legal and illegal immigration, open borders, two tier policing, the integration of communities with conflicting and contradictory belief systems, the axing of winter fuel payments for pensioners, net zero costs and the impending increases in taxes for the people of Britain.

How the Labour government navigates its way around these issues will determine whether it remains in power. The future of Britain as a stable, unified and functioning country is at stake as it could all too easily descend into a balkanised failed state.

Navigating the Alphabet (children’s poem)

To get from A to B to C
I’ll have to take a compass
with me and D to E to F I’ll need
a map but I’ve left it on the
shelf. So from G to H to I I’ll
be guided by the sun in the
sky. From there I’ll travel to
J and K and L so I’d better make
sure I locate a hotel and after a
hearty breakfast it’s off to M and
N and O where I’ll have a much
better route to go. Then on to
P, Q and R and a night spent
reading the stars and off to S
T and U where the cliffs and
the sea provide an amazing
view and onwards to W, X, Y
and Z where after a tiring
day out it’s time for bed. And in
the morning it’s all the way back
to A, B and C for you and me.

Upheaval..

I've just returned from a pretty hectic day of poetry reading and listening. It seems lately that my life is in constant upheaval. At one time I was organised (or at least I tried to be) but lately I seem to rush from one event to another. I don't seem to have a timetable. Actually it's probably not a bad thing for at least I'm active and busy.

Anyway I'm not going to talk about personal upheaval but more about geological upheaval. I have an interest in geology but no sound education on the subject. Lately I've taken to watching programmes on the forming of the Earth; from these I've gathered snippets of information that I don't necessarily remember correctly. Why only this week I watched a programme about the demise of dinosaurs... however at the same time I was looking at train timetables (an example of my personal upheaval).

From this programme I gathered (rightly or wrongly) that a HUGE meteor or asteroid crashed into the earth with the force of 5 billion " Hiroshima's" ...5 BILLION? Did I hear correctly ...did I remember correctly? This led to the extinction of the dinosaurs after 10 million years of inhabiting the earth! I can't imagine such huge figures! However without this catastrophic event that mankind would not have existed. Well, this just blows the mind !

Then another programme informed me that the Lake District Fells were once the height of the Alps and only glaciation and erosion have brought them down to the size they are now! Of course I might have got it all wrong...
 
This doesn't however detract from my rather vague interest in the formation of our geography. I've always been an avid reader of maps. For me, maps are a whole book of information, absorbing me for hours. I sort of "enter" the map... exploring history, geography, archaeology, architecture, town planning, canal building, railway routes, reservoir construction, road building, drystone walling, the effects of glaciation, erosion, follies, monuments... the list goes on ..it's all there ...all you have to do is look. It's often with this looking and tracing routes I've walked... or I'd like to walk that my 'timetable' for the day goes all to pot.

Scafell in the Lake District

Over the years I've written quite a few pieces about the formation of mountains, islands, lakes etc so I've got two pieces of poetry this week that illustrate geological upheaval. I do hope you enjoy reading them.

        Trotternish ( Isle of Skye)

         Twixt sky and sea there is no line
         Only a far off island does define
         The horizon at a distance.
         Misty shapes loom out of the sea -
         Mountains formed by volcanic eruptions,
         In a time not known to Man.
         But science has told us the tale
         Of tectonic upheaval, shifting plates.
         Fire, ash, lava.
         Dark columns rising from the deep.
         Mountain tops smoothed by glaciers,
         Glens scoured out by mighty action,
         Moraine blocked corries, isolated in splendour.


         Goatfell ( Isle of Arran)

         Mirrored sides facing south, gathering the sunlight.
         Rugged peak stretching to the sky- touching clouds.
         Stark grey slabs set on sideways- pyramid like...
         Inviting, but daunting. Head in the mist,
         Feet in the peat moor.
         Majestic peak , scarred from apocalyptic upheaval.

Thanks, Kath (Lady Curt).

A map for life ....

Maps .... many of us would be lost without them! (Ba-bum-tush)

Seriously though, at some point you're probably going to need one in your life. Helping to broaden horizons and directing us in the right direction, you can't beat a proper map (except if you're looking for a new build which isn't on your map which inevitably was printed the year before). Even sat-nav's get directions wrong. I'm sure you have heard a tale of someone being directed down a farm track into the middle of nowhere or even being told, by said sat-nav, to drive straight ahead, even though there is a cliff in front of them. Like I said, you can't beat a proper map!


Directing life's journey:

Plotted before
from A to B
the journey 
seems simple.
Following the plan
to the letter,
ignoring the branches
leads to a predictable,
dull life.
Exploring those 
small deviations
broadens horizons
and minds.
Like a medical chart
maps out
the veins and arteries
bringing crucial blood
to vital organs,
valuable knowledge
is acquired
by seeking out
the smaller byways too.
Each path essential
to a full existence.


Take an adventure one day. Go along the road less travelled (taking care of your personal safety obviously). You never know what you might find!

Thanks for reading. ;-) x
