    It’s really simple.

    Sound is air vibrations at different strengths (volume) and frequencies (pitch). Taller waves are loud. Thinner waves are higher pitched. The math looks like this:

    Volume * sin( Pitch * time)

    Generally, low pitch sounds are louder and easier to see in a sound wave. A kick is really easy to spot. The rest of the weird janky movement of the sound wave is like a bunch of these equations added up to create the sound… generally.

    The trick to understanding sound is that it’s a difference over time. The change in pressure is registered by your brain. A record player is literally just the physical transcription of this math and the speaker is just oscillating back and forth to reproduce the sound.

    Okay maybe it’s not super simple, but I hope this helps.

    I’ve heard an american nurse’s perspective who’s had to clean uncircumsized children. What I gather is thar americans are so generally unhygenic and neglectful that it’s extremely common for parents to bring in children for cleaning when things go wrong. She thinks circumscion is a medically sound option.

    The american government thinks circumcision is a cost effective preventive measure, which makes sense if you’ve seen the price of healthcare. The rest of the world generally agrees that this practice isn’t super effective, and it’s primarily fueled by judaism and islam or aesthetic.

    I’ll spare the horror stories and scary diagrams for my fellow man. I’m against circumcision. Have you seen what it looks lile after surgery and how much pain the baby is in? The diaper hurts them.

    We don’t complain about having to clean baby girls. Not to mention the risk for irreversable damage that can reduce pleasure or be painful for life.

    I think consenting individuals should participate in the anatomy of their body and not have that choice taken away by religious/lazy parents.
