Barometer reading

My barometer pressures have dropped from about 1010 yesterday to 970 on my traditional barometer and 959 on my electric weather station. There is always a discrepancy of about 10 (millimeters of Mercury?) between the two.

What is ‘pressure’. Pressure is air pressure, the weight of the air pressing down on us from the top of the atmosphere downwards.

The guage on the traditional barometer has gone from fair (gold pointer) to rain with the black pointer.

How is pressure measured? One ‘bar’ of pressure is the average air pressure at sea level. It’s also measured in millimetres of Mercury.  There was a historical experiment to find out about the air pressure. The experimenters put a tube of  mercury upside down in a glass dish. This can leave a vacuum in the top of the tube. If you have the tube and dish at sea level the Mercury will be at a lowed level in the dish. This is because a larger weight of atmosphere is pressing down. Go up a mountain and the level in the dish will rise, because the air pressure up there is lower (less depth of atmosphere).

There is lots of information on sites like Wikipedia about air pressure. They probably describe how the air circulating in the atmosphere causes areas of low and high pressure. The weather is also influenced by the sea and its temperatures and the heating of the Earth’s surface by the sun.

Climate change

Walking round Trentham Gardens yesterday I saw a banana plant in flower, in this country, in mid September?! It is usually 5 or 10 degrees Celsius cooler than this.

The last four years have been the hottest in Britain (and the world?) ever. Climate change is a massive problem, its complex, but people are coming out on strike. Children have been showing today how much it means to them. Everyone needs to push the people in power to take action. To share technologies that reduce the need for power in the form of fossil fuels and nuclear energy. Sustainable engineering like wind and wave power need integrating into the worlds power grids. Solar energy should also be exploited. We have got to solve global warming fast if we can.

Metal working tools…

And other images from the Forge at Etruria. I was there today and took a few photos in the beautiful mid September sunshine we had today.

When the sun is bright and low it casts deep shadows and picks out intricate details that you might otherwise miss.

The glow from the flames of the Forge added to the atmosphere, you can almost feel the heat coming off those flames.

The Forge is the domain of Sculpted Steel. You can see demonstrations of the blacksmiths work on open days at Etruria Industrial museum.

Sun through cloud

The sun was shining through the clouds at Spode this afternoon giving everything a moody look.

Grey clouds, leaden

A glimmer of sun

Bright, yellow, hot

Sizzles through the clouds.

Humid heat festers

Industrial view languishes

Only a few plants

And a cat sleeping in the dust,

But alive,

Better than ruins.

 

Comfort food

DSC_2132

What’s your favourite comfort food.

Mine is simple, banana and custard…

Recipe, to make two portions.

1 large or 2 small bananas per person. 

2 heaped table spoonfuls of custard powder. 

2 flat tablespoons of sugar (but I use 1 flat table spoonful of sucralose based granulated sweetener)

1 pint of milk.

Method,

Chop the bananas to bite size pieces and put aside in two bowls.

Put two heaped table spoons of custard powder in a mixing bowl. Add sugar (or sweetener). Use less for thinner custard and less sugar for less sweetness.

Add a small amount of milk to the powder to make a thinnish paste.

Put the rest of the milk in a pan and bring to the boil.

Pour the boiling milk onto the custard paste and mix till the custard has dissolved into it.

Pour the mix back into the pan, bring to the boil and continue to boil for a minute or till the custard has thickened. Once it is ready pour over the bananas.

Eat! Don’t forget to wash up.
