Absolutely no one:


Science Shorts: 6:40 *BIG D*

[idk_jojo]

I thank you for making such a well explained video but i lost it when he said "BIG D" 😂😂😂😂

[tobycaunce]

First channel Ive found with Physics A Level videos without a boring, dull voice-over😂. Thank you!

[Scarletchi]

If anyone has any money they can donate they should. Not all heros wear capes. You are a legend good sir.

[shanikaanderson]

am i the only one who loves the way he writes and draws

[snhtsljedc]

I love how he’s trying to act innocent and ignore at comments who talk about BIG D

[ericsonofjohn]

I used to hate electricity...then I watched your videos on it and now have a new found love for it. I used to hate waves, I’m currently watching your videos on them and I have a new found love for them. Thank you.

6.40 best moment and it's not even mechanics...haha banter

[mrhatter]

gagahahahaI CHOKED AT BIG D

also please do some worked examples for this? Pls pls

[aliaslam]

who s watching this few days before physics paper :((((

[sar_jayy]

Thank you for making our lives easier ! You're one of the best teachers ever !
You explain the difficult concepts in such an easy manner... Love you for that sir. I'm done with your waves series and now I'm moving on to electricity. This world needs teachers like you and Mr. Walter Lewin.... Hats off to both of you !

[tinadop]

Just wanted to say that that was so helpful thanks

[cyndawu]

Oh my word. You have no idea how much I struggled with this experiment exam question. I went to websites to text books and I still get very confused. You saved my life. Your video is amazingly detailed and organized. Hopefully, I do well in the predicted grade exams. Thank you very much :D

[dualityofideas]

Thank you for your whole series on physics, it was well presented and you've made it simple to grasp the concepts. Even though it was aimed at A levels. I used it to understand the concepts required for MCAT.

[fobiastation]

I learned from you rather than spending loads of money to classes
Great teaching sir 👍

[nicolek]

god bless you, you just explained grating better than my textbook and my teacher combine, thank YOU

[asifalamjoy]

Your explanation was fantastic . Till the last moment of watching this, I scared of these wave stuffs. But watching this video has made my concept clear. It makes me to smash the face of my physics teachers the way they explained such as interesting thing. God bless you brother

The AQA A-level spec also mentions that students should know uses of diffraction gratings - one is xray crystallography, which is used to identify elements. This is also how DNA was discovered (by Watson and Crick, I think)

[stanpeter]

First of all, it was amazing! I really understood a lot.

Did you really have to emphasize the "big d" part? I lost it when you said that lol

For A-Level pupils in my last job, I built a device that demonstrates De Broglie’s theorem. A laser passes through a diffraction grating creating an array. A motor spins the diffraction grating to produce the rings
