Sunlight grass and flowers

A warm evening, so we walked along past this grassy area. Unfortunately I’d forgotten I have hay-fever, (it’s just the start of the season) so I walked round with my eyes itching!

I think the flowers are buttercups and dasies, Is there is a song with those words in it? Good to see the flowers though. The bees were buzzing around and enjoying them.

We walked about three miles, we saw a few people and actually chatted at a distance, but it was good to get out.

Daisies

This summer I hope to see daisies and Vinca

green leaves and yellow flowers.

Aquilegia is fading, Poppy flowering in sun.

The garden changes so fast,

you have to run to keep up…..

climbing roses tower over paths,

Sweet showers of rain swell the fruit………………………………………

Soon it will be autumn again.

Fallen leaves and dead flowers.

Enjoy the sun

While you can.

Daisy type flowers

One of my favourites. The centres of these are a multitude of flowers with petals round the edges (think of sunflower hearts). There are oxeye daisies and osteospermums, cone flowers, asters, all sorts of types and colours. Life in all its variations can be wonderful. This photo is of Rudbeckia I think, taken at Trentham Gardens in the autumn. What I like about daisies is the length of time throughout the year that they flower. They cheer me up.

Have you ever made daisy chains? We used to when we were kids. Pick a daisy and make a hole in the stalk with your fingernail parallel with the stalk, then thread another daisy through till the flower head is in contact with the stem. Then do again till you have a chain. (I’m not suggesting you do this, just how we did it, you shouldn’t pick wildflowers).

White and yellow daisy type flowers remind me of sunshine. The dark leaves could be space and the greenery earth. Strange how a picture of petals and leaves make me think if the universe.

We need light to live. Heat from the sun warms us enough to keep the planet temperate. Light allows plants to photosynthise and create Oxygen. Without sunlight we would just be a lump of rock and frozen gasses in the infinity of space.

But it goes further than that…. the first chemical that was present after the big bang, was Hydrogen. Atoms of hydrogen were pulled together by gravity to form stars. Stars are nuclear reactors, the more hydrogen they gather from surrounding clouds of gas, the heavier they get. Eventually nuclear fusion begins and the stars light up. Hydrogen atoms join together and create Helium….

After a while (a few billion years) the stars will have converted most of their Hydrogen to Helium, and further pressure changes that to heavier atoms, from Carbon, upwards in increasing atomic weight. Eventually the star is a cinder of Iron.

But once a star is mainly burning Iron atoms, it needs to use more energy to turn the Iron into heavier elements than the Iron can provide. The energy from it also helps keep the layers of material in the star supported, or expanded. The pressure of radiation and photons of light hold the layers of star plasma up.

Then the star uses up all its fuel . If it is small nothing much may happen and it just burns out. But if it is large enough the pressure from radiation and light is not enough to hold up against the force of gravity which is trying to make it collapse.

The inward pull of gravity can make all the atoms collapse inwards, making a neutron star. A tiny ball of it will weigh a massive amount.

But if the old star is heavy enough it continues to collapse, then the energy created by the collapse can cause the stars outer layers to explode outwards. This may be a Nova, or Supernova. Supernovae create a flash of light that can be as bright  as a whole galaxy.

If the star was even bigger it can collapse completely and create a black hole. In that case the gravity of the black hole will not allow matter or light that comes close to it to escape. There is a complete absence of light.

Funny what thinking about daisies can do to you.

Apologies to the physicists, chemists and biologists out there for my rambling explanation. I’m short on facts and figures but I do like to think about these things.
