Instead of saving for my kids' college, I make videos using the money I would have saved.
The thought is it will help educate the world as a whole, and one day generate enough revenue to pay for their education. Until then if you appreciate what you've learned in this video and the effort that went in to it, please SHARE THE VIDEO!

Has anybody else noticed you can 'break' persistence of vision? For example, if you look at a really fast moving object, like a spinning tire, or ceiling fan it looks blurred, but if you dart your eyes away from it, or towards it you can see a single 'frame' of the action?

I think Smarter Every Day is one of the few YouTube channels where I actually feel like I've DONE science, I fully understand and feel involved in learning it

Yup, the island was white and gold, no doubt on that!

The light house made me go back 3 times. I love natural illusions. Thanks for the trip.

Destin, I'm a 44 year old Australian atheist and I wanted to say two things.
1. I am a HUGE fan of yours - you are a genuinely likeable, fun, curious person and even coming up with the topics for your channel must be a labor of love.
2. I really and truly appreciate your quiet, gentle ministry of the Biblical verses at the end of each episode above the pic of what I think is Reepicheep - the Narnia series is another such example of beautiful, gentle, calm ministry of Christianity. I wanted to tell you how much that means to me.

Dr. Stuart Anstis was a high, high quality guest expert <3 So so much fun to listen to, did such a good job explaining everything with fluidity and depth!

So level with me... Did you see the colors on my island photo?
Also... if you'd like to take a poll on what the colors looked like to you, here you go:

You are the opposite of a TED talk but in the right way, less talk, more show and tell. I love TED talks as much as everyone else but I like to see THINGS instead of a slideshow. Thanks for giving me something interesting to watch and unwind whilst also learning. Looks like you have a great time doing it too.

Destin has the ability to explain the most complicated ideas in the easiest and most interesting way!! I am officially addicted to this channel.

the circuit board blew my mind way more than the picture thing. he populated that in an hour! that’s mind blowing.

The one issue I have with this video is that Destin says that if it wasn't 30fps we would begin to see flicker. That wouldn't happen because the frames aren't displayed and then removed before showing the next frame as a film projector does. What actually happens is that one frame is shown and then instantly replaced by a new frame so that there is always a frame visible. If you lower the frame rate, the video would just begin to look choppy and unnatural and at a certain point, our brains wouldn't detect it as motion at all, but as a slideshow of images.

I was so scared that there was going to be a jump scare lol

[cidgundyr]

I feel dumber every day because i am seeing you guys getting smarter :'

[jordanburns]

Plot twist:
Actually only the first 2 milliseconds of the video were real and your brain made up everything else.

My fiancee was freaking out because when she went to try out her wedding dress that she tried out 5 months ago looks yellow. Her mom, sister, and bridesmaid also agreed and freaked out. They accused the store that they were selling her a completely different color (another version of ivory). They were 100% convinced that the store were pulling something funky. She came crying, and I asked her: What was the weather when you first tried your wedding dress? Answer, it was a super bright, clear day. When she went the second time, gloomy, winter day. Also, ask her to show me a picture of the time that she tried her dress back in July. Well, she had a full, summer tan and dark hair. Second time, her skin is pale from the winter, and she died her hair blonde. I told her to try dyeing her hair back to dark brown, and get a spray tan. I explained that color is defined by three elements: the object (constant), the observer (brain - not constant), and the light source (not constant). She went back to try on the dress. She came back crying tears of joy, "babe, you're a genious!". Her dress was a brilliant and beautiful as she remembered. I told her, I'm not a genious. I watch SmarterEveryDay.

That spinning LED board is just like a very early version of television. Say Destin, you never fail to get me excited about the subject you present. Perhaps your own enthusiasm is instantly contagious?

Great content! You’re a very smart man. YouTube needs more of this
