Reading Definition and 636 Threads

Reading is the process of taking in the sense or meaning of letters, symbols, etc., especially by sight or touch.For educators and researchers, reading is a multifaceted process involving such areas as word recognition, orthography (spelling), alphabetics, phonics, phonemic awareness, vocabulary, comprehension, fluency, and motivation.Other types of reading and writing, such as pictograms (e.g., a hazard symbol and an emoji), are not based on speech based writing systems. The common link is the interpretation of symbols to extract the meaning from the visual notations or tactile signals (as in the case of Braille).

    Intro Physics Suggestions for conceptual E&M and modern physics reading

    I'm looking for suggestions of resources to learn introductory E&M and "modern physics" (I'm thinking relativity, QM, particle) conceptually. This learning is out of self interest. While my focus is for conceptual understanding, this doesn't mean any suggested resources should be devoid of...

    Water activity meter reading over 1

    Good evening. I recently was taught how to use our new water activity meter, and I noticed something strange. This meter uses changes in the reflectance of a mirror. Whenever we'd bring the sample up to temperature, the measurement would reach a low point, then at about 0.5° below our set...

    Normal force reading on a scale -- How and why?

    Homework Statement let's say you have a regular bathroom scale, which we know measures the normal force that it exerts on a person aka. apparent weight. Now let's say that we didn't know that it measured the normal force when a object was on it. Obviously we still know that the only two forces...

    "Reading" Schrodinger's equation

    I am starting to learn Quantum mechanics. I can't wait for my completion of QM, as I am running behind all the concepts taught in the class; but I can't even go on studying chemistry, or I can't even analyse anything, without understanding the atoms in reality. I believe in (Russell's??)...
