The Body Electric: Signals and Systems
Like Duolingo, but for The Body Electric: Signals and Systems. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
Free during early access · No credit card · iPhone & Android
Key ideas in The Body Electric: Signals and Systems
- Cells pump charged particles across their outer skin to build up pressure
- Electrical signals cannot jump the physical gap between cells directly
- Opening tiny gates lets these particles rush back in to create a pulse
- Chemicals act as a bridge to restart the signal in the next cell
- How a nerve cell generates its own electrical charge for a pulse
- The sequence of events when a signal crosses the gap between neurons
- Nerve signals are waves of charge, not moving physical objects
- The signal moves instantly while the atoms in the nerve stay in place
- Opposite charges create a pull that can drag other molecules along
- Cells build up a 'battery' of ions on one side of a membrane
- Muscles require a specific 'push' from charged particles to move
- Minerals provide the raw materials for the body's electrical signals
- Stored ions act like a dam waiting to be released
- How the body uses charge to move specific molecules into cells
- The movement of charge is what actually does the work
- The consequence of losing the balance of salt and potassium
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives The Body Electric: Signals and Systems the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
When a signal reaches the end of one nerve cell, why can't the electricity simply spark across to the next one?
