Long time no see Clip to Evernote

I didn't post entries during last few weeks. As you might notice from my Twitter posts, I came back from Rome without troubles. It was great being in Rome! I want to say thank you to all people I met in Rome. I uploaded photos I took in Rome, though some of these are missing titles and descriptions. I hope you enjoy these photos!

As I twitted, I stopped updating my Tumblr and started using Delicious. My FriendFeed now feeds kwkbtr’s log (this blog), Twitter, Flickr and Delicious (and If you want to keep track of my activities with one feed, I recommend using it.

As I wrote on the homepage, I will present a poster “Interference between independent bosonic fields under U(1) superselection rule” at QIT 21 in Tokyo on 4 Nov 2009. If you have time, please check it out!

I realized that it is hard to start writing in the diary again after stopped for a while. But anyway I finished one entry! I hope I can establish my pace, not only of updating this web site but also of my everyday life.

As I am not a native English speaker, there might be some grammatical mistakes in my English writings. If you find them, please let me know. I appreciate any comment :-)

Mathematica地獄 Clip to Evernote

Mathematicaで数値計算をやろうと思い超短時間での習得を試みるも、いまいちすっきり理解できず。本当は時間をかけてちゃんと勉強すればいいんだろうけどなあ。でも、プログラミングMathematica(Roman E. Maeder 著、時田 節 訳)の日本語が読みにくくてしょうがないのは私だけでしょうか。誰か、Mathematicaの精神がきちんと理解でき、かつ読みやすい本を教えてください。

QIPCのsocial programの申込を忘れていた。危ない。というか全然準備できてない。焦る。

日経サイエンス Clip to Evernote


日経サイエンスを書店で眺めた。Weak measurementの特集。まあ、two-state formalism(って言うんだっけ)自体は面白い考え方だと思うので、いい意味で妄想を膨らませて何か出てきたらいいですね。「負の確率」を強調するのはなんだかな、と思うけど。

桂キャンパス訪問 Clip to Evernote



桂キャンパスを訪問した。Nゲージに深く感動した。フォトニック結晶の話と光合成系でのanti-Zeno効果の話とweak measurementの話を聞いた。講演者の皆様お疲れさまでした。飲みに行ったときに出た話だが、(anti-)Zeno効果には、(非局所性のような)量子系に特有の性質は本質的ではないのではないかという気がする。皆さんはどう思われるでしょうか。
