中文简介: | 观察,测量和数据记录是科学的核心活动。投机和新理论的发展也是至关重要的,但最终必须根据实际情况对这些理论产生的预测进行测试,而这只能通过进一步测量来完成。无论是使用诸如标尺和温度计等简单仪器进行测量,还是使用电子显微镜或激光等复杂设备进行测量,都需要决定如何表示结果,使用哪些测量单位以及精确到将进行测量。在这个单元中,我们将依次考虑这些点。 |
课程简介: | Observation, measurement and the recording of data are central activities in science. Speculation and the development of new theories are crucial as well, but ultimately the predictions resulting from those theories have to be tested against what actually happens and this can only be done by making further measurements. Whether measurements are made using simple instruments such as rulers and thermometers, or involve sophisticated devices such as electron microscopes or lasers, there are decisions to be made about how the results are to be represented, what units of measurements will be used and the precision to which the measurements will be made. In this unit we will consider these points in turn. |
