Hello your videos are awesome but it would be cool to have just the audio on a platform like Spotify so I can listen and do other thing at the same time thanks :)

[novokid]

Very good video; explains a concept of oscillations and producing radiowaves that I struggled to understand before :)

[leonardogoncalvesjacometti]

your videos are truly amazing, thank you

[georgebaker]

This was very helpful with my science work

[nishtakasundass]

I started to love waves after watching this.

Cognito,


any idea when space and cosmology will be discussed for Edexcel IGCSE and GCSE physics.
Hertz-sprung Russell Diagram, Development of Stars etc..

Bro helped me with a science project he is a walking w
