    The Bible doesn’t say that you shouldn’t edit or correct the Bible because the authors of the Bible didn’t have the rest of the Bible.

    Moses gives some explicit commands to the Israelites to not modify the commands he gives in Deuteronomy, but that doesn’t really apply to the other books.

    Likewise, some guy named “John” warns against anyone adding or removing from the account of his acid trip in Revelations, but that doesn’t really apply to other books.

    The “Bible” was constructed over a long process and while what many think of as the “Bible” was finalized by 400AD there are still disagreements today (See Judaism, Catholicism, Protestantism, Pentecostalism, Mormonism, and many other smaller sects).

    The original authors wrote disparate works for distinct purposes at distinct points in time. They were not writing with the goal of manufacturing a multi-thousand year story bound as a single volume.

    How do we know the full story?

    We don’t. We use archeology, biology, anthropology, and other scientific disciplines to determine a likely path of the story of humanity as a whole. Some disciplines use the books of the Bible and other contemporary accounts to guide areas of future study, but if you want a single source for the history of the earth, humanity, or even the Israelites the Bible isn’t going to offer an honest perspective.



  • A microphone is a membrane attached to a means to generate electricity (like shaking wires around a magnet). When you make sound by a mic you shake the membrane and it in turn generates a small amount of electricity.

    This electricity is an analog signal (it’s continuous, and the exact amount changes over time). We can take that signal and digitize it (literally chop it up into distinct digits) by using an ADC or analog to digital converter. Essentially an ADC takes a snapshot of the analog signal at a specific point in time, and repeats that snapshot process very quickly. If you take enough snapshots fast enough you can have a reasonable approximation of the original signal (like following a dotted line).

    Now we have a digital signal and we can store those series of snapshots in a file.

    But how do we turn that back into sound? We literally just follow the process in reverse.

    We open the file and get the list of snapshots. We pass those to a DAC or digital to analog converter that generates a continuous analog signal that passes through every original point. We pass that signal to thin wire wrapped around a magnet and attached to a membrane. This mechanism takes the small generated electric field from the DAC and causes the membrane to shake in the same pattern that the mic originally shook in.

    In practice there are often other steps in line such as amps to increase the strength of a signal or compression to minimize how much space the snapshots take up.
