See what you would learn
Understand the physics behind ordinary things.
A course on physics through the everyday: why planes fly, why the sky is blue, how electricity reaches your kitchen, why ice floats. It explains the ideas in plain language you could pass on to a child.

Before the course is built
Setup asks about your situation first.
Lesson 1 opens on the moment you describe, and the examples use your role. For this request, expect questions like these.
- Which everyday mysteries bother you most?
- How did physics go at school: fine, badly, or not at all?
- Do you want to explain things to children, or just understand them yourself?
Right for now
If any of this sounds familiar, start here.
A child asked and you did not know
Why is the sky blue is a hard question.
Physics at school was equations
None of it connected to the world.
Course arc
Where the course goes, in order.
Cadence writes the lessons for you, so the exact path follows your answers. This is the ground a course built from this sentence covers.
01 / 06Forces and motion
Why things fall, float, fly and stop.
Heat and energy
Why coffee cools, why ice floats and where energy goes.
Light and colour
Why the sky is blue, sunsets are red and mirrors reverse.
Electricity and magnetism
How power reaches you and why magnets stick.
Waves and sound
Music, echoes and why the bathroom sounds good.
Explaining it
Passing the ideas on without equations.
What changes
What you will be able to do, and what you will stop believing.
You will be able to
Explain everyday phenomena
Describe why common things happen in plain words.
See physics around you
Recognise the same few ideas operating everywhere.
Pass it on
Explain to a child or friend without losing the truth.
Ideas this course corrects
Physics is about equations
Equations are the precise language. The ideas can be understood without them.
Everyday physics is simple
The everyday is where the deep ideas show up. Why ice floats is genuinely subtle.
Course questions
What to know before you start.
Is this a fixed course?
No. Cadence builds the course when you type the sentence and answer a few setup questions, so the lessons follow your situation. This page describes what a course built from this request covers. You see the whole path before Lesson 1.
Who is this course for?
A course on physics through the everyday: why planes fly, why the sky is blue, how electricity reaches your kitchen, why ice floats. It explains the ideas in plain language you could pass on to a child. It sits under Science & nature in the Ideas & discovery part of the library.
Do I need any prior experience?
No. Setup asks what you already know and where you want to use it, and the course starts from there. Bring a real situation if you have one; the examples are built around it.
How long does it take?
Courses run 7 to 30 lessons of about 10 minutes, sized to what you asked for. One lesson a day is the intended pace, and you can go faster. Lessons can be read or played as audio.
Does this course award a certificate or degree?
No. Cadence is for practical self-learning and does not award accredited degrees or professional certification.
