Dancing Girl

Now I came across this today and I’m not quite sure what to make of it. Many people are praising it while just as many are unsettled by it.

Check it out: http://www.news.com.au/perthnow/story/0,21598,22492511-5005375,00.html

Some people see her spinning clockwise, others see her spinning anti-clockwise. If you stare long enough you should see her change direction. Some people can make her change at will. Though no-one can make her move both ways at once.
Apparently its achieved by an unchanging animation of only 34 frames on a constant loop.

It is believed that the two-dimensional image does not contain enough three-dimensional information to tell the brain which way she is spinning. Therefore your brain fills the rest in, as is often seen in many optical illusions. Hovever in this case the brain can do it in two ways depending on which side of your brain you favor.

Now I’m not one of the people who is greatly disconcerted by this but im intrigued that rather than see her spin occasionally I see her go back and forth or side to side.

So what do you make of it?

I met Ray Mears on Sunday!Ray Mears

He was giving a lecture and by virtue of my mother I managed to get a ticket. After the lecture he was signing his books and I was able to talk to him. He is a very dedicated person and I admire the work he does trying to preserve a dying skill.

Bushcraft is something that has really interested me. Just the thought of going in the ‘wilderness’ and managing to survive is inspiring to me. But then our ancestors did it and that way of life lasted longer then ours has and was not so detrimental to the environment.

By the way did I mention I met Ray Mears.

paintballing.jpgHello again, sorry its been such a long time since my last post. It’s just been a cumulative effect of preparing for exams, sitting them, being lazy and recovering from exams and being more lazy. Oh yeah and the small thing of applying for uni.

Anyway the other day a couple of friends and me went paintballing, we’d been planning this for months as a stress reliever after the exams. So eventually we all arrived by various means of transport including scrounging lifts from parents, friends and friends parents bearing in mind few of us can drive and fewer have access to a car. Anyway all 15 of us eventually made it and were all in good spirits, being all experienced from the one time we’d been before.  Though two or three hadn’t been before and we all reassured them saying, “Its doesn’t hurt, you’ll be fine”. We finally get kitted out after more than a long wait and collect our guns and go for the safety briefing. The first thing the marshal says, “If anybodies told you it doesn’t hurt they’re lying!” we grin behind our masked as there are a few audible intakes of breath from the newbees.

After all that we get down to the whole shooting each other thing and find out the other team mainly consists of squadies and this one cocky guy in just a tee-shirt. So we taught him a lesson (he he). Which consisted of paintballs on skin. However that didn’t last too long as we were promptly decimated by the squadies who had much better aim, vastly superior tactics and more money to buy ammunition with as the MoD was paying their wages and we were all students. We did come back at the end though by defending the barracks effectively. So the score was only 1000 – 300 which wasn’t a total loss.

I think the main problem with our team was the lack of communication, and these two girls who didn’t seem to get that your meant to shoot the other team not your own. But please note I’m not saying girls are stupid or unable to grasp the complexities that is tactics in paintballing, seeing as last time there were three girls who were well impressive.

At paintballing i mean…

Einstein

Einstein the Genius of his day and still ours, did you know his teachers called him thick or problem child or something like that you get the idea. Anyway in my Physics lesson the other day we were eventually formally introduced to his legacy. One of the reasons I took Physics and now 1 year and 6ish months later I get to use his equation E=MC2. Its not really anything special the way in which we use it anyway. But it does pose quite an interesting point.

From the equation you can see that energy (E) is equal or proportional to mass (M). The C2 is just speed of light squared and like a constant not important right now. However going back to E = M this means the more energy something has the more mass it has. This makes sense because your car has more mass when it has more petrol in it. The petrol being the energy in stored form.

This seemingly normal fact got us physicists thinking. When you are at the top of a skyscraper or in an aeroplane wouldn’t you have more mass as you have more potential energy. BTW potential energy is like a store of energy the higher you are the more you have as you have further to fall. So that means every time you go up the stairs you gain a small amount of mass. For some reason we really found this funny, I don’t know if you agree but there it is.

We thought about it some more and then with a bit of help from our teacher realised that you really do not gain any mass as it is lost as CO2when you breath. So fear not you are no heavier when you ascend the stairs, probably lighter due to the exercise.

Though please note when I talk about mass its only in very small amounts, tiny even.

I read this the other day and thought it was so good I had to share it, this is basically an e-mail from a Wife to her Husband:

To my darling husband, before you return from your overseas trip I just want to let you know about the small accident I had with the pick up truck when I turned into the driveway. Fortunately it wasn’t too bad and I really didn’t get hurt, so please don’t worry too much about me.

I was coming home from Wal-Mart, and when I turned into the driveway I accidentally pushed down on the accelerator instead of the brake. The garage door is slightly bent but the pick up fortunately came to a halt when it bumped into your car. I am really sorry, but I know with your kind-hearted personality you will forgive me. I am enclosing a picture for you.

Your loving wife.

Hello world!

Hello everyone,

This is my first ever blog, and i’ve been thinking about getting one for some time now. For me this is a way to communicate my ideas, feelings and thoughts. But more importantly to rant.

So you are very welcome and hopefully this will be a two way process.

By the way SilverBack is a nickname that I was branded with a little while ago and kind of appealed to me.
