『音の原子』完全な周波数分析が可能な音の最小継続時間は0.093秒。fast Fourier transform(FFT)アルゴリズムの実装によるスペクトル音楽と疎表現の可能性、及びWavelet変換によるフィールドレコーディング音源の粒状合成とコマンドライブラリの構築。

Well, the short answer is .093 seconds. That’s about the shortest amount of time mathematicians need to generate a full analysis of a sound’s component frequencies.

Armed with the calculus technique of the Fast Fourier transform, mathematicians typically take the amplitude values from a mere .093 seconds of sound and draw a complete audio portrait. This portrait consists of the volumes of each component frequency that makes up a complex sound.

□ Franck Bedrossian / "Manifesto"

>> http://outhere-music.com/store-AECD_1106

フランス、スペクトル楽派の流れを汲む若手の急先鋒、Franck Bedrossianの作品集『Manifesto』。鋭利で凍てつくような音の凝集体が、無機的でながら何処か生温い幻夢の響きを奏でています。


※ スペクトル音楽…「複雑な音響をオーケストラで再現するために、フーリエ変換による音響の解析、周波数変調を初めとするアナログ変調、内挿といった情報理論とその工学技術が駆使（Wikipedia:トリスタン・ミュライユの頁から抜粋）」する等といった音響学的技術が実践された楽曲群を指す。

因にFranck Bedrossianは、スペクトル楽派を推進したGérard Griseyに師事。

□ NatGeoSociety: Time Travel Not Possible?

>> on.natgeo.com/kjOveU

タイムトラベルの不可能性 - メタマテリアルとレーザーを用いた原始宇宙の再現による否定。 ミンコフスキ空間における擬似粒子のエントロピー的振る舞い。

この宇宙モデルでは、粒子は過去に辿った経路を遡行できない為、その無秩序性に依り、時間逆行を理論上可能にする粒子経路の『輪』が完成しない。『如何なる次元においてもエントロピー増大が起きる』ことが重要なのかもしれない。

私たちは「時間の矢」のような『過去』と『未来』の概念を書き換える必要がある？
→「時間」は、それ自体が散逸する無秩序性によって決定されている事象を顕現する。

In the toy model, the equivalent of time travel would be for a plasmons to complete a loop that runs along the exact same path it had previously traveled. But once the plasmon has strayed from that path?due in part to entropy?making the loop is no longer possible.

RNA dynamics deconstructed: RNA plays a critical role in directing the creation of proteins, but... http://bit.ly/ebQgEN

The scientists harnessed an existing technique to trace the fate of newly produced RNA and paired it with a new sequencing-based technology that counts molecules of mRNA.

The results also gave the researchers a view of some of the in-between steps, during which mRNA is edited or processed -- an unexpected but serendipitous finding. "That's the beauty of sequencing: it has a very extensive view so it shows you things you didn't expect to see,"
