[고2] 25년 10월 - 35번: 물리학에서 측정 단위 선택의 임의성과 그 의미

Consider units of measure, one kind of descriptive device we are familiar with using in physics. Spatial distances can be given in terms of feet or meters or some other unit, and the physics will be the same regardless. We conclude from this that physics does not prefer one unit of length over any other, and we may choose any one we like for reasons of convenience. We further conclude that any feature depending on that choice, such as the particular numerical value assigned to the spatial separation between two locations, is not out there in the world apart from a choice of unit. Temperatures can likewise be given in terms of the Fahrenheit or Celsius or Kelvin scale, and nothing in the physics changes when we switch from one scale to another. We conclude that the choice of scale is an arbitrary choice in description, and that any feature that depends on that choice is scale-dependent.

We further conclude that any feature depending on that choice, such as the particular numerical value assigned to the spatial separation between two locations, is not out there in the world apart from a choice of unit.
5	Temperatures can likewise be given in terms of the Fahrenheit or Celsius or Kelvin scale, and nothing in the physics changes when we switch from one scale to another.	Temperatures can likewise be given in terms of the Fahrenheit or Celsius or Kelvin scale. Nothing in the physics changes when we switch from one scale to another: any of these describe the temperature facts equally well.
6	We conclude that the choice of scale is an arbitrary choice in description, and that any feature that depends on that choice is scale-dependent.	We conclude that the choice of scale is an arbitrary choice in description, and that any feature that depends on that choice, such as whether one object is twice as hot as another, is scale-dependent, not out there in the world apart from a choice of scale.
7	(문제 지문에 없음)	Since physics does not recognize or pay attention to differences in scale or unit of measure, since the physics is the same regardless, we infer that the choice of unit or scale is merely an arbitrary or conventional choice in description.
8	(문제 지문에 없음)	There is no “unit of measure structure” in the world. Different units or scales simply provide different, equally legitimate ways of describing the world.
