2.1 長さの縮みと時計の遅れと質量の増大 はじめに空間（長さや距離）

2.1 長さの縮みと時計の遅れと質量の増大
はじめに空間（長さや距離）と時間（時計）と質量について考える．特殊相対性理論では，静止慣性系における物体の長さ☆はその物体がその静止慣性系に対して速度☆で運動しているとき，その運動方向に，光速を☆として☆に縮み（ローレンツ収縮し）短くなり，運動方向と垂直方向には何ら縮まず☆のままである．また同じく静止慣性系における時計の刻み☆は，その時計がその静止慣性系に対して速度☆で運動しているとき☆に遅れてゆっくり刻むようになる．さらに同じく静止慣性系における物体の質量☆は，その物体がその静止慣性系に対して速度☆で運動しているとき☆に増大する．
ここでこの長さの☆への縮みや時計の☆への遅れや質量の☆への増大は，本当に実際に実在的に縮んだり遅れたり増大したりするものか，そうではなくて観測的にみかけ上縮んだり遅れたり増大したりするようにみえるだけで，実際は縮んだり遅れたり増大したりすることは起こらないのかということについて考える．今までの特殊相対性理論の解釈や，教科書や解説書，啓蒙書の記述では，すべて前者がとられており，実際に縮んだり遅れたり増大したりするという解釈であるが，ここでその実在的な解釈は誤りであって，観測的にみかけ上縮んだり遅れたり増大したりすると考えねばならないことを示す．元々そうなる（即ち縮んだり遅れたり増大する）と考えないと，相対性理論全体が一般相対性理論も含めて，実在の物理的世界を表さなくなってしまうということから，実際にそうなると解釈されているのであるが，これから議論していくようにそれは誤りであって，相対性理論は光にかかわるものを除いて実在の物理的世界を表すのではないのである．
まず長さの縮みについて，慣性系☆において静止している長さ☆は☆が長さ ☆の方向に慣性系☆に対して速度☆で運動するとき，慣性系☆からみると☆ に縮んで☆に観測される（☆へ写像される）ということである．即ち☆に縮んでいるのは☆に写された☆の☆のことであって☆そのものではないのである．これを今までの特殊相対性理論では☆の長さ☆そのものが静止から運動すると ☆に実際に縮む，と間違えているのである．長さの実在値は縮まないが観測値が縮むのであって，この実在と観測を混同して，観測値と同じく実在値も縮むとしているわけである．あるいは観測値が縮めばその向こうの実在値も縮むとして，みかけ上のものを実在のものと同一視しているのである．ここで速度というのは相対的なものであるから，☆から☆をみても同じことがいえる．.即ち☆に静止している長さ☆は☆からみると☆に縮んでみえる（☆に写像される）．.実際の☆の☆は縮んでいない．要するに相対速度☆の二つの慣性系から互いに相手をみると，実際には両方とも縮んでいないのであるが，互いに縮んでいるようにみえるということである．この実際には両方とも何ら縮んでいない，というところが本書と観測力学で新しくした重要なところであって今までの教科書や解説書，啓蒙書などには書かれていないことである．

2.1 length of the contraction and the clock delay and the mass of the increase
beginning in space (length and distance) and time (clock) think about the mass. In the special theory of relativity, when the length of the object in the still inertial system ☆ is that the object is moving at the speed ☆ against the still inertial system, in the direction of motion, the shrinkage in ☆ the speed of light as ☆ (Lorentz contraction c) shortened, the movement direction and the vertical direction remains no shrinking without ☆ in. The same tick of the clock in the still inertial system ☆, the watch is so chopped slowly late in ☆ when in motion at a speed ☆ against the still inertial system. Further object of mass ☆ is in the same stationary inertial system, increases ☆ when the object is moving at the speed ☆ against the still inertial system.
Here, the increase of delays and mass ☆ to the to the length of the ☆ shrinkage and watch ☆ is either really really realistic to shrink Dari delay or to increase or to those, observed manner is not the case Just it appears to be or to increase on a shrink Dari or delay apparent, actually think about the fact that what does not happen to be or increased or delay shrink. Interpretation and of the special theory of relativity up to now, textbooks and Reference, in the description of the enlightenment certificate, all has been taken is the former, it is the interpretation that or actually shrink Dari delay or increase, real that here interpretation is a mistake, to indicate that it must be considered or to delay or increase shrink the apparent observation manner. If you do not believe so made ​​originally (ie, contracted to increase or delay Dari), the entire theory of relativity is the general theory of relativity also be included, since it is that no longer represent the physical world of reality, it is actually Sonaruto interpretation While in than is that it as we discuss now be erroneous, relativity is not I represent the physical world of reality except those related to light.
For first of length contraction, when ☆ to have length ☆ the death stationary in inertial system ☆ exercise against inertial system ☆ at a speed ☆ in length ☆ direction of, shrinks to ☆ when viewed from the inertial system ☆ It is that the observed (mapped to ☆) to ☆. That's has shrunk to ☆ it is not something that ☆ be that photographed the ☆ Bruno ☆ of the ☆. This special is in the theory of relativity ☆ length of up to now ☆ itself is actually shrinks when you exercise ☆ from a stationary, it is of that mistake. The length of the real value of a than shrink but observed value does not shrink, and then confuse this reality and the observation, it is not as well have been the real value is also contracted with the observed value. Or as an observed value contracts also real value of the beyond if shortened, it is of being equated with those of the real thing on the apparent. Because here's that speed is relative, it can be said the same even look at the ☆ from ☆. . That length is stationary in ☆ ☆ it appears to shrink in ☆ when viewed from ☆ (is mapped to ☆). . Actual ☆ ☆ Bruno has not shrunk. In short, we look at the opponent each other from two of the inertial system of relative speed ☆, but is not yet shrunk actually both, it is that seems to shrink with each other. This fact to both of you do not shrink any, that place where textbooks and manual ever be a place important to the newly in this book and the observed dynamics, in such enlightenment certificate it is that it is not written.

On the contraction and the length of the delay of the clock and 2.1 mass increases at the beginning (or long) and time (the clock) and the mass of the special theory of relativity ， stationary objects in inertial system, the length of the object to the static inertia system in - speed when the movement in the direction of motion ， ， and light - to - shrinkage (Lorentz contraction is shortened ，) remains in the movement direction and in the vertical direction, but also in any contract that the clock in the static inertia system, ，This is the same watch for the static inertia system in - speed moving slowly away, when the delay is more like the rest of objects in the inertial mass, ， object to the static inertia system in - speed motion is increased when the.
