Infinite memory

I read an interesting article tonight about a woman who has an infallible memory of events from her life. She remembers everything - every single little thing - that happened to her since the age of 15. A couple of interesting things from the article:
- she remembers events infallibly, but not facts. So she didn't do particularly good on memory tests and also she didn't shine in school. So that's kind of useless right?
- For her, the adage "time heals all wounds" doesn't apply as she remembers all bad events clearly.
"I don't look back at the past with any distance. It's more like experiencing everything over and over again, and those memories trigger exactly the same emotions in me. It's like an endless, chaotic film that can completely overpower me. And there's no stop button."

For someone who has a horrible memory of both events and facts, a perfect memory is very very desirable. And yet I am not sure if I could accept not being able to rely on time to heal some of my wounds. It's funny how the disadvantages of certain gifts are not always clear.

Happy Pi Day!

What's so special about the following poem? (Try and answer with out reading the article)
Sir, I bear a rhyme excelling
In mystic force and magic spelling.

The article is actually really interesting. I love this one:
"in 1873, William Shanks announced he had found 707 digits over years of hand-cramping work; unfortunately, he had made a mistake after the 527th place. The following digits were all wrong." D'uh!!!

Also... "Pi Day is a time to honour not just a number and our fascination with it, but also the essential truth that there are some things we simply cannot know. We can only get close to knowing."

Nikola Tesla

Recently the hubby and I watch the movie The Prestige with Wolverine and Batman. In the movie, Wolverine contacted Nikola Tesla to build him a teleportation machine. Now as any physicist or engineer will tell you, Tesla is a name that is regularly heard in relation to magnetic fields and AC current. But I thought to myself, "how did Tesla get involved in the movie and the whole idea of teleportation? Why did the directors think of Tesla?".

After reading the following article, it all became clear! I knew Tesla invented AC current but wow - he invented so much!! and it seems he was famous for running currents thru his body to light up bulbs. Many argue that his work was much more important that that of Edison and yet the latter won is credited with more. Also there is some debate whether Tesla invented radio waves or it was really Marconi who is considered to be the father of wireless communication.
And then there was Tesla's idea of sending waves thru the earth (so called terrestrial waves) to maybe light up every part of the earth? :-) was he responsible for a huge explosion in siberia?

He seems to have been an amazing inventor.

I recommend reading this article to get an idea. It doesn't require any background knowledge and then you will see why he is the man :-) Also a lot of things that are referenced in the movie now make sense!

New Birth

Amazing pictures that capture the moment a dolphin joins the world.

The blood is kind of disgusting but ehh... I've heard human birth is also not the prettiest moment! yikes!!
On a related note... if this happened in the wild, would sharks be attracted by the blood? :-o
