A long time ago, when I doing my apprenticeship in an electronics workshop, I was looking through a cupboard looking for a test box, when I found a small diecast box labelled “The flying arsehole”. I asked my boss:” What’s this?”, and he told me to plug in the power to plus/minus 12v, and the outputs X and Y or an oscilloscope X and Y. I did that, and presto! I saw a circle which expanded and contracted and moved round the screen. It was making a Lissajous figure which was being modulated to make it expand and contract and get a small offset to make it move around the screen. It looked exactly like there was an “asshole” flying round the screen. I put it back in the bottom of the cupboard, and as far as I know it’s still there, amusing apprentices for generations to come!
This is great. I feel like the section where you were greenscreened could have benefited by labeling which of the waveforms was being represented in the x plane and which was in the y plane. I lost track and had to use some of my attention capacity to figure it out instead of listening.
Now this is some really phenomenal explanation. Thank You for your time, Sir.
This is beyond and comprehensive, so so thanks to you sir !
The optical experiment and the real world application are great! I greatly appreciate your effort!
Thanks.
This was an amazing explanation. Incredibly detailed and thought out. Thank you!
Glad it was helpful!
Wonderfully explained...
Underrated.
Nice work.
Thanks.
This video requires more than one like button
WoW So well explained!!!
Where where you when I was learning physics!!!
Fantastic! One of the best explanations!
Very math help ty sir.
Thank you very much Sir!!! Hepled me alot for my FINALS
Amazing !!

Quite Well Done
Loved this explanation. Thank you so much
phenomenal explanation. Thank you very much sir
Thanks and welcome
The experiment were really great 😃
great video 🔥
Thanks 🔥
A Very clear and nice explination. I enjoyed watching your video
Thankyou
Loved the video! Have you other examples of lissajous figures use in physics?
THANK YOU SO MUCH....
Thanks sir from india
Are so also the shapes of electrons orbitals?
What would a 3D lissajous pattern look like? What if the ratios aren't integers, or are they always integers but just very large?
Thank you sir
You’re welcome
thank u 😊
Very well explained. Where were you when I was in high school?
Thankyou.
Polska Gurom!
Try and make it stationary
Can u speak hindi or punjabi please 🥺
No
