Welcome to the Smarter Every Day subreddit! It’s a place for those addicted to learning and to look at the world differently each and every day.

Our goal here is simple: To encourage an atmosphere of learning.

You should want to become "Smarter Every Day" and I hope our fascination with science, the world around us, and its governing physical laws somehow motivates you to do this.

Is the LockDown app discontinued?

All I get is a "Internet connection lost" message when I try to use it.

All my other apps connect fine, it's not my WiFi.

Anyone know what happened? It's hard to Google for answers because "LockDown" is such a common phrase.

Help Finding Episode?

I watched an episode on a streaming service last night (I think it was Disney+) and it combined a few different glass experiments Destin has done including breaking windshields as well as a bullet and Prince Ruperts drop. I recommended it to a few friends but can’t find the combined episode anywhere??? Apparently Disney+ doesn’t store viewing history. It’s driving me crazy. I think the episode was 22 minutes long but it could have been 24. Someone please help!

I'm looking for the video about Fort Morgan and Mobile Bay that Destin covered.

Hey all, I remember Destin making a video about Fort Morgan, on the Gulf Shores peninsula, and the Mobile Bay. I've tried searching youtube to no avail. I suggested my parents visit there in a few days as I enjoyed my visit at the fort years ago. If y'all could link or comment the name of the video to give my parents a better experience, I'd really appreciate it!

P.s. I loved the first Thinkercon!!! Any news on another convention happening?

EDIT: Thanks all. Guess I was thinking the NDQ podcast episode Damn the Torpedoes was a video; kind of speaks to the podcast's quality. 👍🏻 Check it out below, if you're not in the know.

I need everyone's help for a second.

For a while now I've been looking for something very specific, and if I know the people that watch Dustin's videos you can all pull through and help me here.

I've been looking for something relatively small snd mechanical too "fiddle" with. Just something to admire the amazing work that went into the craft and manufacture of the idem.

For example as of late I've come into the possession of a 1890s handrail with a amazing ratchet! I became absolutely obsessed with the satisfying click and mechanism that made up the relatively simple ratchet.

I know this is vague but I know that this is the single best group of people I could ask a question like this too.

Taught some colleagues how to put on snow chains on the car.

I suppose this just as well could have been an r/mademesmile post, but the last guys comment, "Today I got smarter" made me think of this sub.

Nanotubes. I’m not sure if this has been asked or if an appropriate place to request; what are your thoughts on Carbon Nanotubes? Have you considered doing any video content about it for your YouTube channel?

Heard a story about "the craziest rescue" by the Coast Guard

The pastor at my grandparents' church told this story from a Coast Guard rescuer in Florida. The pastor asked the Coast Guard pilot what the craziest rescue he'd ever done was and the pilot told this story. (It's second hand so I apologize for the lack of information)

These two teenage boys had taken a small boat out off the coast of Florida and eventually got too far out and couldn't get back into shore. A rescue operation was initiated by the Coast Guard to find the 2 teens in the boat. It eventually got dark and they continued searching in the dark using their night vision goggles. (They were using the grid search pattern. I don't remember how that was important to the story). Eventually, one of the pilots noticed a tiny light on the horizon. They reported this and proceeded to investigate the small light. They flew 17 miles away from where they had been searching and found the two teens in the boat.

After rescuing them and taking them back to the mainland, the pilot said to the teens, "it was a good thing you had that light with you. We wouldn't have found you without seeing the light." The teens replied, "we didn't have any light with us." The pilot asked what they were doing then to make the light he saw. They explained they had a cigarette lighter, but it was empty and wouldn't light. So they kept striking the flint wheel creating a tiny spark. That spark is what the pilot could see in his night vision goggles from 17 miles away.

Need help understanding the airplane on treadmill question.

So I am confused here. I completely understand that the wheels of an aircraft are free flowing and therefore not relevant to the conversation but I still do not understand how a plane would be able to lift off from a treadmill.

All my Google searches have stated it will but I still do not understand why.

The treadmill keeps pace with the plane’s speed, therefore the plane is stationary in relation to the ground, therefore no airspeed.

Why is the answer “yes”?

Am I looking at this wrong?

Edit: missing word and an incorrect statement

Has Destin published any papers?

Or has his work been cited in any papers? I remember him talking about that in the whip video, and the vortex ring video also comes to mind.

Destin, if you see this, you're awesome and thank you

As Matt Parker and Adam Savage put it in their podcast, I'm kind of a poly noob. I'm not a scientist nor engineer, I don't have the technical skills, rigorous knowledge these people have, but I like to learn a lot about different topics and build intuition from all of these. I have over the years gathered bits of knowledge here and there. It doesn't help in any "useful" way at all, but when I learn something, or when I think about something I have enough of these bits of knowledge to kind of understand where I'm at, and what to look for.

Obviously Destin has been a big part in my learnings over the years. Him and many other awesome engineering and science focused channels.

But what I want to thank Destin for is the focus he puts on the people behind all of this. It's kind of the only of the big "science" channel that does it. It's awesome.

In this day and age it's easy, at least for me, to feel disconnected. Of course there was this huge lockdown thing, but apart from that we're living more and more disconnected, distrusting lifes. We don't see people, we see systems, and anonymous profiles, and corporations, and "stuff just happens". You can go out and buy groceries without needing to talk to anyone at all. It's not a critique, just a fact.

So to see Destin always talking to the people that make the stuff happening, shaking hands with them, it just feels good. It's kind of nothing and silly in the "grand scheme of things" or whatever, but it's simple. It's human. And it makes me feel good.

And I think that if from time to time I catch myself thinking about all these invisible workers, all the people that spend hours of their time and a lot of energy just to make stuff work, at all levels, and have this feeling of "damn human society can be awesome", it's in part thank to Destin and his channel.

So thank you Destin, for constantly bringing awereness to the human part behind everything. Every process, every bit of work, every thing that is produced, manufactured, designed, shipped, transformed, at one point, was touched by a human hand.

People in their 20s what do you do to get smart everyday like what are some must skills to develop that can help you in the long run

I was wondering how do we learn to become discipline and build that strong mindset to open ideas and learning to think outside of the box. How do we train our mind to learn new things instead of feeling foggy all the time. What are some self growth skills to develop in your 20s

Would Destin do a podcast about Huntsville?

For a few months I have been listening to Troy do his podcast about the people and things in and around Huntsville.

I would love to see Destin do this. I am sure he has a lot of great "Destin" stories to tell!

Einstein of Agriculture - Will Harris of White Oak Pastures

Check out this Joe Rogan Podcast with Will Harris, owner of White Oak Pastures, a revolutionary family farm utilizing REGENERATIVE agriculture and humane animal husbandry practices. Here's a clip of the podcast.

Joe Rogan and Will Harris, a fourth-generation cattleman and farmer from Georgia, discuss how factory farming with a lot of machinery and chemicals is bad for the long term sustainability of our farming lands, as well as the quality of food we get from these plants and animals. A major shift is under way back to resilient sustainable regenerative farming.

White Oak Pastures is where I order my meat from.

When people ask you why you use, "big words", what do you tell them?

Might not be the right place to post, but just as the title says, when people ask why you choose to use a certain complex word over a more simple term, what is your explanation?

Does you fingerprint leave a unique signature on the water ripples when running it around a wine glass to create a sound?

Pretty much like the title. Does you fingerprint leave a unique signature on the water ripples when running it around a wine glass to create a sound? Or will the same frequence have the same ripples? Or, is it impossible to recreate someone else's ripples and therefore sound, due to the fact that each fingerprint is unique?
