前回の話を絵図にして 今回の話に　繋げよう

2022zionad @2022zionad

Let's create a visual representation of the previous discussion and connect it to the current one.

古典力学と違って 存在ではなく 情報を扱う物理では デカルト座標の扱いが どうなるか　 確認しよう

2022zionad @2022zionad

In contrast to classical mechanics, where the focus is on existence, in physics that deals with information, let's examine how the treatment of Cartesian coordinates is affected.

電子線や　x線を　 資料（サンプル）に　ぶつける サンプルは　アミノ酸や　タンパク質 アミノ酸や　タンパク質の ３次元　立体構造を知りたい

2022zionad @2022zionad

Blasting samples with electron beams or X-rays, the samples being amino acids or proteins, we aim to understand the three-dimensional structure of amino acids and proteins.

宇宙の部分空間に 原子複数を構造的配置した状態が サンプル物質塊（かたまり） 　 この部分空間に 電子線や　x線を　ぶつけて 電子線　ｘ線の散乱を 平面スクリーンで検出する

2022zionad @2022zionad

In a portion of space within the universe, where multiple atoms are arranged in a structured state, there exists a sample material block.

2022zionad @2022zionad

In this specific space, electron beams or X-rays are directed towards the sample material block. The scattering of electron beams and X-rays is then detected using a flat screen, capturing the diffraction patterns.

平面スクリーンに 散乱の痕跡が　点描画になる 点描画から アミノ酸や　タンパク質の ３次元空間内の　原子配置状況を　求める つまり構造が　 平面スクリーンの痕跡である点描画　 ２次元イメージの逆算で　求まる

2022zionad @2022zionad

On the planar screen, the scattered traces form a dot pattern. From this dot pattern, we seek to determine the arrangement of atoms in the three-dimensional space of amino acids or proteins.

2022zionad @2022zionad

In other words, the structure is deduced from the dot pattern on the planar screen, reverse-engineering a two-dimensional image.

カメラレンズを通過した後に 光線達が通過する　集合位置　 焦点 設計図では　点大きさ

2022zionad @2022zionad

After passing through the camera lens, the rays converge at a specific position, the focal point. In the design blueprint, it is represented as a point size.

電子線や　強力なX線を　 資料（サンプル）に　ぶつける場合は サンプルは　複数原子が存在する 宇宙内の　部分空間

2022zionad @2022zionad

When directing electron beams or intense X-rays onto a sample, the sample exists in a subspace within the universe and comprises multiple atoms.

囲碁の碁石を置くとこは　格子点 将棋やチェスの駒を置くとこは　マス目 点位置と 部分空間の違いはあるが ここでは　ほぼ同じで扱い

2022zionad @2022zionad

Placing Go stones occurs at intersection points, while chess or shogi pieces are positioned on squares. Although there is a difference in terminology between points and subspace, in this context, they are treated almost equivalently.

純度を高めた アミノ酸や タンパク質を　抽出し 資料（サンプル）にする

Extracting purified amino acids and proteins, increasing their purity, to be used as samples.

Placing that at the focus (impact point) of electron beams or intense X-rays.
