Diameter?

How do you work out the radius of a satellite dish when all you know is its diameter? That was the strange question I tried to answer on twitter last night.

First of all I had to remember my school girl maths from fifty years ago.

I remembered the diameter if found with the formula 2 pi r. Where pi is 22/7. I couldn’t remember the decimal version and I wasn’t using a calculator so I divided 7 into 22 and got 3.142. Then r is the radius, which is half of 70=35.

So then I had to multiply (on paper again) 2 Xx 3.142= 6.284. And multiply that by 35. As my multiplication is not good I added 3 lots of 62.84 together = 188.52, then added 6.284 together five times = 31.41 (yes it’s long winded but accurate). Add the two figures together and you get 219.93.

I don’t know BODMAS or PODMAS or whatever they are called. But I actually got it right. Not to bad for an oldie!

PS the formula for area is pi r squared. Not going there!

Dragon illustrations

For my final college report I’m looking at the history of the depictions of dragons (OK very niche). I’m trying to understand how they were illustrated and how they change across the world. I’ve found out Korean dragons have five toes, Chinese four or five and Japanese three toes. They have different shapes. They go from serpentine to with two or four legs. No wings or wings. Some are fire-breathing. They may be mythical but they seem to evolve.

Mural in Fenton Cafe

Mural at Fenton Town Hall by an unknown artist. It is painted in tiny squares (like pixels) and based on a plate design of an oak tree, cottages and a tumble down fence. I’ve seen it before about two years ago. Now it’s much more complete. It’s a huge picture. Very interesting and beautiful.

I had been told by staff there that it had been painted by a particular artist. I’m afraid that was not true and I’m happy to set the matter straight and confirm it was not painted by her.

cat dragon

used basic photoshop drawing tools to turn my cat into a dragon. She was stretched out on the bed this afternoon and the way she was lying was just right for this.Added some blue sky, and with that cute look it just worked, she could be twisting and turning in the air ready to land on the top branches of a tree, ready to furl her wings and sit and have a peaceful wash or she might be ready for mischeif? Whatever she does she will remain cat sized and gentle.

She could also be a bat cat, or a magpie cat. Genetically manipulated to be catwomans friend, you saw it here first!
