Tide

Time and tide wait for no man

Tidal reef,

High tide……

Why tide?

The Moon pulls on the Earth and the Earth pulls on the Moon. They are gravitationally linked so that one face of the Moon always faces us and the water in our oceans is attracted upwards towards it by its gravity. On the other side of the world there is also a rise in the waters because there is less gravitational pull on the oceans because they are futher away from the moon…..

Why high tides?

The water is pulled up so far by the moon, but as water flows inwards towards the land as the tide comes in it can also rise further if it is pushing into a narrowing area such as a gap between two islands or into the narrowing channel of a river or stream. In this case sometimes the water can overtop the banks if it is a particularly high tide, such as a spring tide. The water will rise higher if it is forced into the estuary by wind as well as tidal forces.

One third of the world’s population live on various coast lines around the world. If the world continues to warm up then these people will be at risk from the rising tides caused by global warming. Many countries have built costal defenses but these are being damaged every year during stormy weather. Replacing the damaged protective barriers is being abandoned in some places as not cost effective and some costal salt marshes are being recreated to protect the land.

Astronomical paintings

I love the challenge of trying to paint and draw astronomical objects. I have painted the Earth a few times, but also the Moon, the nebula shown here, Jupiter, and done digital drawings of the Earth and Moon, and the Veil Nebula plus other objects. I have also drawn Jupiter and Saturn.

I’m not an expert. They were all done without measuring the positions of features or stars, so for a real astronomer they probably look totally inaccurate. Still the universe is a wonderful place and the objects in it are amazing.

So if you can recommend an object I could have a go at painting I would be interested. I can’t promise it will be perfect. But I would have a go.

Skies

One thing about living in a temperate climate in the Midlands of England is the variations in the sky. We might have just had one of the hottest summer’s on record, but like most people here I am waiting for the rain to come back. The country usually gets enough, but at the moment satellite imagery shows the grass burnt to brown instead of the greens of summers. Trees seem to be fairing better because they have deep roots. But hopefully when the rain comes down from the sky the land will recover.

Skies….

Clouds fly on the breezes and winds,

Blue skies soon turn grey,

Magic sunsets illuminate the sky,

Stars shine out on high.

Shooting stars obscured by clouds,

Planet’s seem so bright.

Moon and Sun in turn appear,

Sometimes Moon hides Sun.

Look up, look up, into the air, not just to the ground,

Above your head the sky astounds,

The world below is gone.

 

Well I do like skies. There is something called the cloud appreciation society which has interesting information about clouds. They suggest blue skies are boring, and watching the different sorts of clouds is the thing to do, from cirrus, cumulo nimbus, asperatus, mammatus, stratus, so many names. New cloud formations identified. ..

Skies are such a barometer (no pun intended) of our atmosphere. I would hate to live in a country where the weather stayed the same for months.

Don’t stare at me. .

Instead of poetry a few words……

Large green eyes, look out of a dark green face. Paper thin skin, layers of chlorophyll ? What are you,  green, sap green, olive green, hookers green, lime green, a green apparition. Staring eyes that cast a spell over my mind. A sneer on your lips, worldly thoughts cascade in your brain.

What are you? Again, I think. Some mammalian plant? A simulacrum of humanity?

Leaves break out through your skin, vines, ivy, convolulus. Grow longer, twisting violently across your face. Your hair is fern fronds, feathery, tiny leaves on twining stems….

Your body is green as grass, a cauliflower and cabbage mass of leaves, courgette fingers, marrow thighs, feet stretching into the mud, but mobile like a human woman.

Veins like phloem and xylem gather fluids, rise up your trunk. Transpiration instead of breath. Are you deciduous or evergreen? Do you have an autumn season and wither into winter? Or are you still young in the cold months? Red berries blossoming on your lips? Heart of Oak or Yew?

You stand and stare at me. Looking into my room, glass holding back your strength. Your witch like hands or twigs beat on the widow pane. You cannot enter. But I cannot leave. Trapped by your tangled leaves. Tendrils fight their way in through the letter box. Green woman, earth, Gaia ….

 

 

Snow

IMG_20180801_223026_651something cool on a hot evening…

❄❄❄❄❄❄❄❄❄❄❄❄❄❄❄❄❄❄❄❄❄❄❄❄❄

Snow

Falling ice in slivers,

Mass of shakes and shivers.

The cold, blue white, icicle,

Rain turned soft, showy, beautiful.

All flakes are different they say,

None have the same symmetry. ..

Hexagonal, six sided

Wind and air embroidered.

Vast blizzard made of tiny stars devine

of silvered sheen, your shape defined.

Snow.

Cold.

White.

Feathered.

Chilling…..

Ways to prove the Earth is not flat!

PicsArt_1532810951522

I keep hearing about people who think the Earth is flat so I decided to do a thought experiment to see if it is possible…

• If the Earth was flat it would be daytime all over the world at the same time, or night time all over the world.

• The sun would rise at the same time everywhere and set at the same time.

• There would be no equator, and all parts of the world would be at the same temperature.

• There would be no north and south poles and no northern or southern lights.

• There would be no need for time zones.

• Flat earthers say the horizon is flat, but that is because the globe of the Earth has a very large circumference.

• If the Earth was flat boats would not go over the horizon.

• If the Earth was flat you would be able to see all the way to the other side using a powerful telescope on top of a big building.

• If the Earth was flat we would be able to travel to the edge.

• A flat Earth would cast a flat shadow on the moon during an eclipse of the moon. (this is because the Earth is between the Sun and the Moon when it happens and if the Flat side was facing the Sun if would be overhead and you would not see the moon, but it would cast a circular shadow).

•  Finally….If the Earth is flat….what’s on the other side? Is it Elephants and Turtles all the way down? ( according to Terry Pratchett)

The live and dead tree

IMG_20180728_172922_812

The live and dead tree sits hard on the ground.

One twist of bark still attached…

Like Ivy clinging to the trunk,

Twisted knotted rope like round and taut.

 

Green leaves, large and serrated, sprout out,

Twigs and branches caught in the embrace,

Dead wood holds up life to the sun,

Wise, wide trunk so aged.

 

How did you die?

We’re you struck, hit, broken, by wind or storm?

Did you find disease in your skin?

Is the clinging umbilicus of your wooden baby your clone?

 

Your age is ancient, your body skeletal.

Your upper limbs and branches peeled of all skin.

But still you sit hard on the ground,

Immortal, in a way reborn.
