Day 866 : Open the Door!



I didn't know that now my daughter can open the door to the entrance hall of our house.
Of course, it's a great pleasure to see her growth day by day, but it's a big headache to see she plays trick daringly step by step... :(

Day 866 : Friends



Today, my daughter visited a house of friend, and there 3 kids got together.
During their mothers were chatting, they looked like watching TV, playing with toys and various things.

But, according to my wife, my daughter looked like withdrawing into her own wold, didn't join other kids well. :(

Day 859 : Drawing



Yesterday, we went to BABiESRUS, and bought some drawing sets.
In the above picture, my wife is drawing Dokin-chan of Anpan-man for my daughter using a water pen. It's cool because it uses no ink, and there is no afraid spattering the floor. :)

But, the only problem is that pictures are of course volatile, and thus I have to carefully watch what my daughter is drawing to take pictures of them. :o

VAIO CW

Today, we went to Yamada Denki and bought a new PC for my wife.

My wife's choice was SONY VAIO CW, and I was a bit surprised because she wanted a BluRay drive.

,

It turned out that actually she wanted to watch "THIS IS IT" by BluRay media... :o
(It contains more bonus tracks than DVD version.) :)

BTW, I also spent my youth enjoying Micheal Jackson's tunes. So, I also enjoyed "This Is It." :)

Gödel's incompleteness theorems



Gödel's Incompleteness Theorems
Kurt Gödel (Translation and expository writings by Susumu Hayashi and Mariko Yasugi)
ISBN 4-00-339441-0

This is a unique book on the Gödel's incompleteness theorems.
It consists of 3 parts.
The first part of of the book is a translation of the original Gödel's paper, ant the second expository writings by the translators on historical perspective of foundation of mathematics mainly focuses on works of David Hilbert, not the theorems themself. This is because it's essential to understand the historical background why the theorems were discovered.
The third part is an annotation of Goedel's original paper, and furthermore the translators tries to reconstruct Goedel's thoughts when he discovered the theorems.

Actually, I picked up the book at a book store to have better understanding on Penrose's theory on consciousness, but the book is more than my expectation. :)

I'm not sure if there is an English translation of the book, but I believe it's worth reading anyway. :)

Snowy Tokyo



In Tokyo, we have snow usually once or twice a year, and today is the first snowy day of this winter.

It's around 9:00pm when it began to snow. So, my daughter didn't recognize it's snowing...
I'm wondering what she would say looking at the scene tomorrow morning. :)
