Wow, was looking for a doppler effect sound byte and found this, watched it on a whim, was instantly enthralled. Teachers like this are so rare. Definitely gonna watch a lot of these tonight.

Best explanation of doppler effect i have ever seen... Thank you

That circle is freaking perfect!

you explained so good... my gratitude from Nepal...

This guy is actually the best

i really liked the way this sir had hopped up and down seriusly he has a good sense of humor and that plup plup plup is ringing in my head throughout!!!!! thumbs up for him

I grew up in Colombia, studied my highschool physics in the 90s with Mr. Hewitt's book. It inspired me. I'm now an engineer thanks to him, I still whisper to myself "física física física" when facing a problem....

its so easy to understand him that after two weeks of struggling trying to figure out what the doppler effect is, i finally understand!

-Starts with a W .. -Ripples I'm deaying xD

Hey Paul, this is espectacular really im amazed of how awesome yo teach classes, with this video I really learned the Doppler effect. Thank you , regards from Uruguay

Best explanation video ever

Very inspiring :) thank you!

Thank you so much this helped me immensely

he explains it so well c:

I wish i had a teacher like you

man i wish I could find an awesome instructor like this

The best explanation .... Better than the blue and red shift! !!!

Omg he speaks so rthymically its hypnotic

Very good explanation, sir

I learned more in these 3 minutes and 12 seconds than i did in 4 hours of my physics class...my teacher got nothing on this dude lol.

This guy is good!!

very good teacher :->

this guy is so good

I want this guy as my teacher for every goddamn science class.

We need more teachers like this, yea ?

Well because the frequency gets to one direction at a different rate than normal. The bug was moving at the same speed but the frequency changed because the ripple of the wave was headed towards the right and than back to the left.

This guy is very amusing

You make me want to take physics more when im in year 12 ;D

i like canadian teachers

cud u pls make a vid explanation bout spacetime, gravity & blackholes.

The left handed teacher said that the change of frequency due to motion is called the Doppler effect. Still I am kind of dazed. Some species,like myself,simply dont get It. Sad,isn't! Hence,Hierarchy.

Could somebody explain why the one increasing is not speed but frequency of the wave ?

If you want to be taught by him, read his book "Conceptual Physics"

Blip blip blip

What grade is this fore?

can this guy be my teacher!?

good teacher, yea?

i want to be that teacher's student :(

RIPPLES! haha

He sounds a bit hiperactive :)

why this video have that stupid frame?

It's the Christian Effect. Doppler Effect? Nah, it'll never catch on, sounds too strange.
