1.1 Information science Definition of information Science Information Science is a trans-disciplinary science with information as its object in study; the laws in information process as its content information methodology as its approach; and the strengthening human information functions particularly the intellectual ability, as its goal

一、黑体黑体辐射 1热辐射(heat radiation): （1)热辐射:辐射能量按频率的分布随温度而变的电磁辐射称为热辐射。 物体由于具有温度而辐射电磁波是物体内分子、原子的热运动引起的。 （2)热辐射的基本性质 ①任何物体(气、液、固)在任何温度下都有热辐射;

1 Introduction Background for New methodology Modern natural science methodology is mainly based on matter and energy Even though matter and energy are still necessitate factors in information system, yet the characteristic feature of information systems, particularly the complex ones, is neither matter nor energy but information Without information, the complex information systems, like brain and intelligent life. cannot be understood

按照原子理论,在每个原子里,电子环绕由中子和 质子组成的原子核而运动~称为电子云 原子核的线度≈5×10m电子云的线度≈5×10m 物质结构理论:

7-1物质的微观模型统计规律性 一、分子的数密度和线度 ·物质的分子是可以独立存在、并保持该物质原有性质的最小粒子

1. Information Processing Definition of Information processing All operations exerted to the information itself for its better utilization Information processing is necessary because most of the information in its original form may not be good for use. Thus information processing is the basis of later operations Two categories of information processing: 1)Shallow Level of Information Processing 2)Deeper level of Information Processing

3-1 Measures of Random Syntactic Information Shannon Theory of Information Key point: 1. Information is something that can be used to remove uncertainty. 2. The amount of information can then be measured by the amount of uncertainty it removed. 3. In the cases of communications, only waveform is concerned while meaning and value are ignored. 4. Uncertainty and thus information are statistic in nature and statistical mathematics is enough
