Rainbow

After the rain, the rainbow. The base of it was really bright. The rain came down so hard and fast, a river of water came down the hill. The forecast is for possible thunderstorms tomorrow following the arrival of ex hurricane Epsilon in the North Atlantic. There have already been strong winds and the leaves have been flying off the trees. Autumn has arrived with a bang!

Clocks going back

Oh no! Clocks go back tomorrow night. What does that mean? Lighter mornings, but it goes dark an hour earlier.

They did an experiment in the 1960’s I think. They kept British summer time for about three years. It stayed lighter in the evenings. The other effect was that there were less accidental deaths of children because they were not going back from school in the dark when they were tired. But it didn’t catch on because sunrise in the North and Scotland was at about 10am. The idea has been suggested a few times since then but was voted down in Parliament. Maybe one day they will change it permanently. I wish they would. It also saved money and reduced power usage. So maybe its worth it.

Distances

I like knowing things, so I thought I would look u some measurements.

The shortest distance on earth I could find was the thinnest section of the crust of the Earth which is only under the deep oceans and is mainly made up of iron bearing rock. That is about 5km.

But the thickness of the Earth’s crust varies between 5km and 70km, so the average would be about 35 kilometers. To give you an idea of how far that is, it’s approximately the same as Dover to Calais, which is 33.3km.

The distance from the Earth’s surface to space is 100 kilometers. Or three times the distance from Dover to Calais.

Going up in size, the distance from the Earth’s surface to the centre of the Earth is 6,371km. Which is 63 times the distance to space.

Now we go a bit further. The escape velocity from Earth is 11.19 kilometers per second. That is the slowest speed something would have to move to fly up into space and leave Earth’s gravity for good. The more massive the object, the more effort it would take to leave the gravity well of an object. So a gas giant planet is huge compared with the Earth but is less dense on average. I don’t know the figures. I didn’t look them up, but I read that if we were as big as Saturn it could gloat on our sea?

Going further out, the Moon, which is the furthest human beings have travelled to after reaching escape velocity is 384,400km away.

If you want to travel to the Sun the distance is 150,800,000 kilometers….

But man-made objects have gone further. We have sent probes into the vastness of space. Voyager Two has left the Solar system and is currently about 18,603,199,501 kilometers away. In distance at the speed of light that’s 17 hrs 14 minutes and 13.5 seconds (approximately) as of yesterday.

Of ccourse that’s nothing compared with the nearest star to our Sun. Which is about 4 light years away from the Solar system. And then… Space is infinite…

Hedgehog in the shed

I just went out to check if there were hedgehogs in the shed. One was eating cat food but scuttled over to the corner as I shone my light in, so I took a quick photo and came out again. It’s quite a cool night so at least the poor thing has some shelter, food and water in there. There is a smaller one somewhere so we might have Hoglets soon. I think the shed needs tidying up a bit. Hubby seems to leave everything on the floor, but as long as there isn’t anything dangerous for the hedgehogs to eat they should be fine. I’ve got details now of the local hog charity so I might get in touch tomorrow. X

Juxtaposed

FB_IMG_1595155239254

Juxtaposed they sat

The jelly mold and the light

Till they got in a fight

The triceratops came off worst

The cat pounced

Paw out

Dinosaurs leg fell off

Juxtaposed in opposition

They growled

And snarled.

Only in the dark

The cats eyes sharp

Wobbled over to the triceratops

Whose battery had gone flat.

Batted it with a jelly paw

Splat!

Now he’s really flat!

Morning time.

Bin time

Sorry you can’t be glued.

Now jelly mold

Hangs it’s head in shame

Magnetised with a hook

To the fridge!

Urban sketchers Stoke-on-Trent challenge today, Light. I had got some new permanent markers so decided to do something colourful. I did use a fine liner pen and a 6b pencil. Also used an almost dried up pale blue felt pen to add some shading to the window frame. The standard lamp has a lampshade covered in sequins. (speckles on the drawing). There will be another challenge in a couple of days. I wonder what it will be….

Rainbow

_20200627_203233

When there is heavy rain overhead but a low sun I know there will be a rainbow somewhere. I looked out of the front door and saw this. I got a bit damp and had to change the exposure to get a halfway decent photo. But it came out OK. We also had a few rumbles of thunder, but it’s not been that bad… Last week the rain was far heavier. Tomorrow might be worse.
