The Black World Of Solitude.

Sunday, 21 June 2009

Ok, so today was daddy's day, so my family went out.

First it's a sunday, and on sundays i have swimming lessons, so i swam first.

After swimming we went to the Da Vinci exhibition. Beautiful. However no photos to be taken, so no pics for now. However there was something that caught my eye.

It was a bridge that requires no ropes to bind the wood together and no nut and bolt. The wood logs were connected by some dent in the wood, but nothing else. The heavier the load, the stronger and more secure the bridge. It was a good design, and I think it's called the emergency bridge as named by Da Vinci himself. The exhibits show Da Vinci's inventions (e.g. the flying machine, the pyramid parachute, etc.) and all his art work. And they have one corner full of Mona Lisa paintings. It's just amazing how that great man did his art using science. Makes his art look realistic.

And then he used math for one of his paintings which i forgot what the name was. It shows a man, hands parallel to the ground and the man standing in a square with his feet close together. It also shows the same man, this time in a circle, with his arms around 60 degrees from being parallel to the ground and his legs spread apart. I remember in the name there was this letter V, but I cant remember his name. There was also the painting "The Last Supper", which I'm not too sure what is it about.

By the way all these took place in the science centre, so if you are interested just go to the science centre. Of course you have to pay money. I think this one and only exhibit ends in August.

So after viewing all the exhibits we went to walk around science centre. When it was time to go home I headed for the souvenir shop and bought this packaging with rocks in it. Costs $9.90. Inside contained the crystal/mineral/rock i always wanted: Quartz.

The last time I bought one in a box and when I squeezed it, I did not feel any electrical charge on it. This effect is called piezoelectricity, where a force on the crystal will generate electrical charges on opposite sides of the crystal. Since there was an instruction manual in the packaging and it tells you how to see a spark appear from one quartz to another, i deduce it is real.

Ok, enough of science, i haven't checked whether it is real or not, will do so tomorrow. After buying the rocks thingy from the shop we went home. Then I turned on the computer and started typing this post.
