Hey r/SmarterEveryDay community!

I am percolating on the idea of an impromptu adventure to take my 8 year old son to see the Eclipse. I saw the one in Oregon in 2017 and it was amazing..

He loves science and gets r/MarkRober 's Crunchlabs boxes every month and loves them, and I'm thinking of flying down from cloudy (and non-totality) Oregon to find a viewing party or event in the Dallas/Ft. Worth area...

Do you or anyone here have any recommendations on events to help me plan? I grew up loving Astronomy and I envision this being a life-changing event for him...

Many thanks,

Leon

Recently watched the video and want to use it as my desktop background. but couldn't find a good-quality picture of this frame. Can someone help me out? I did take a look at the extended video with slow-mo, but the background is not as bright as I like.

​

This is the frame I liked the most

I started supporting Destin monetarily after his speech at NASA and his appeal towards safety and responsibility. Loved that talk btw

I just recieved my Baseball in germany and I'm stoked. Will I recieve last years stickers aswell? I technically started supporting him 2023, but there where no more videos that year.

I'm making loose plans to watch the eclipse. I am somewhat limited on the travel distance I can do. Basically somewhere between Maine and eastern Ohio.

Should I still try and travel to make it if it's cloudy or other inclement weather? I realize this is subjective but wanted opinions. Perhaps someone has done this. I won't have a lot of funds invested, already took a vacation day and really just means a day of driving and $100 in gas or so.

if it matters or anyone curious I'll say I'm around broome/Tioga/chemung county NY

…a human hair would be size of a football field.

I’ve recently been thinking about how atoms are very tiny, (and most of that is empty space.) Putting splitting the atom into perspective.

Common Explanations I’ve Seen Avogadros number is the number of atoms in 22.41 Liters of gas: 6 x 10^(23) which is roughly equal to all the stars in the universe.

A human hair is a 17-181 micrometers across. Atoms are 0.1-0.5 nanometers across. A 140 micrometer width hair would be a 1 million carbon atoms wide.

If an atom were the size of an apple, the apple would would be size of the earth.

The problem with is they relate things and quantities I can’t really fathom in the first place: the volume of earth, the number of stars in the universe are essentially meaningless to me beyond “it’s a lot” which I already knew.

Human Scale Analogy

If an atom were the size of a human hair, a human hair would be the size of a football field.

Both are relatable sizes. I could imagine putting strands of hair side by side and filling a sports field.

What do you think? Any other interesting atom math?

Mentioned here at 2:28 or so

I remembered hearing about Edgerton for the first time from Destin in 194.

Super cool link.

In the first instance of you actually getting the matches to light, why does the last match light before the one that was struck before it? Also can you try this with an air rifle instead of a streight up rifle?

I was using my drill a bunch today with thin drill bits. Ended up breaking four of them. All four broke into 3 pieces. I immediately thought about the spaghetti episode. Does anyone know if it breaks the same way?

They finally removed the last two fasteners on the OSIRIS-REx collection canister and they were Phillips Head screws. I hate Phillips head. Specifically they look like the Torq-Set variety which should extract better but my question, isn't there something better? Particularly for something like this. I've abandoned Phillips for as many things as I can because they are so easy to strip out the head.

How can someone strengthen his intelligence? I mean, we always read that the mind is a muscle that needs training in order to remain stronger, smarter, and have higher concentration abilities. So, what steps can we actually take or specific practices that actually develop intelligence, thinking, problem-solving skills, and concentration? Does anyone know of sources from which we can solve numerical problems and provide an explanation or solution? Could this be a really effective step?

Video if you haven't seen it. https://www.youtube.com/watch?v=W4QSGlM06Gs&t=497s

QUESTION: There seems to be some odd artifacts in some of the slow motions shots in the latest video: Small black rectangles above the matches. In one shot it even seems as if a bite has been taken out of the bullet. If anyone has any Idea what causes this, I would love to know.

MY THEORY: My theory is that it has to do with light reflecting off the bullets and the matches/background or that the phantoms resolution isn't good enough to process the black areas adequately. I did notice this only happens when there is debris flying around. I also don't think it has to do with youtube video compression because it is so focused and appears in different shots.

If you want to go thru and pause the video yourself the timestamps are 9:39 and 8:16.

Now that the 4privacy company has been acquired, what's a good, trustworthy alternative?

I am loving your analog camera and film series. Just wanted to check if you would be interested in talking to someone that is researching how to reconstruct film photos that have gone through long term storage. The chemical reactions that are going on that is shifting colors and degrading the quality as a function of time. A friend of mines father was or is working on a research project in Switzerland in order to better recover the original quality of the photos. I am sure you can find your own sources too of course, but I found it fascinating to talk to the guy, or whoever is working on the project now as I suspect he is retired at this point.

I know the skills of fictional characters such as Sherlock Holmes is far fetched, but the skill of deduction and reading people is very valuable and can be a game changer for anyone.

What are there feasible ways I can improve my deductive skills and people reading skills?

What steps can I take and resources should I use to become a more analytical person using my deductive reasoning skills, and become a better people reader?

Watching the recent SmarterEveryDay video, it's insinuated that 1 Saturn V = 1 moon landing. While in comparison the starship stack would need n (11+) launches to get to the moon. This was obviously done to drive a point, and not a technical truth.
I'm curious how many Saturn V rockets were launched (successfully) prior to the first moon landing?

​

I’m wondering if or when we’ll get another video featuring a rocket, specifically SpaceX Starship.

Hi Destin,

First of all I need to congratulate you on your amazing response to Diana's situation. A huge amount of people are not just unsupportive, but abusive, in cases of chronic fatigue syndrome diseases. You on the other hand do seem to 'get it'. The same goes for Diana's husband, but on an entirely new level. The man is a saint. Thank you both for being there for Diana in the format you have shown in your video. Your visit is exactly what she, and other people like us in the world, need.

Below is the second reason I'm posting here. I also emailed it to Diana's physics girl email.

Hi,

I am a physics researcher from the UK with a similar medical situation to Diana. I have MECFS, and I have had to diagnose and treat myself with MCAS by reading vast amounts of the medical literature.

In addition to treating myself for MCAS and MECFS, I have seen a POTS specialist. Many interventions have helped a little, but there are no cures.

If you want I can double check everything you are doing based on what I'm doing for myself and my (new found) knowledge on chronic fatigue diseases/MCAS. I'm concerned if Diana is still bedbound and she has been diagnosed with MCAS. To me that implies she hasn't been treated adequately- or is extremely unfortunate and not responding to the various medications that need to be trialled in MCAS patients.

If you want my help in any capacity feel free to contact me back. I can send you the resources I've read which I think are the most useful (a couple of scientific papers and books). I can also check what you are doing with Diana in bit more detail. To be clear I HAVE NO CURE, I AM NOT A DOCTOR, but I do think Diana's quality of life can be improved.

I am a very high achieving physicist and was 2 days away from sitting the viva for my PhD when I came down with a mysterious virus that left me with severe MECFS. When I started this journey I had severe MECFS (but not as bad as Diana by the looks of it), and after 10 months of treating myself I'm now at the mild end of moderate MECFS. I still feel awful, however the improvement to my quality of life is immense.

If you want my help email me, I'm in the UK but fortunately we live in the world of the internet where physical location means very little.

I'm not looking for money or exposure or anything like that, just to help a small amount.

Best wishes.

Not sure if this is the idea proposal forum, but here it goes. I work for a department Southern California and I think it’d be an interesting episode focusing on the engineering of the fire service. Some examples:

• centrifugal fire pumps
• drafting water from fixed sources
• diesel engines
• fluid hydraulics
• pump cavitation
• force application with hands tools (forced entry)
• principals of fire
• EMS cardiac monitors
• rope rescue and other search and rescue ops
• aerial firefighting

Let me know if this seems like it could be entertaining or not.

Love your content!

I can read words on the page but I cant extract meaning a lot of the time. I can memorize math formula and apply them but I can't think through how I'd construct simple tools or machines.

I love the idea of puzzle solving and there's some things where I can do well, but generalized puzzle solving doesnt work for me.

Take the three ring and post moving puzzle. I know there's a specific algorithm for it because ive completed it and then gotten faster at it, but my understanding was intuitive, I didnt think "I know how to move these parts" I FELT it. Does that make sense?

I dont want to risk working on this field and not showing anything for it in the end, because it seems like SED is the level of IQ you need to be.

This might be a dumb question, but I was just wondering. If you are travelling at the speed of sound, inside of like a jet for example and you screamed. Would you be able to hear your scream for as long as you fly supersonic?

This is more of a theoretical argument because it's all based on a Pathfinder game, but here is the question. If I took an anvil and shrunk it to the size of a coin with a weight of lets say 1 ounce and then fired it from a sling and the anvil immediately began returning to its original size and say 50 points as it left the sling, would it maintain the same trajectory or would it fall flat?

A few friends and I believe that as the object increases in size, the force imparted on it by the sling would be insufficient to propel it any further, and it would slow down significantly. The person making the argument believes that once the object is in motion, initial force is not relevant, and it would continue traveling at the same speed.

If anyone has come across anything on this, I would love to get a link because I had a hard time finding any discussion on it.

Edit1 - after some research I have settled on the law of conservation of energy and the formula for kinetic energy which is mass times velocity squared concludes that the velocity of the anvil goes to 0 as it returns to full size because kinetic energy stays the same. But the debate is still on and I’ve been told they will not accept the answer unless a physicist agrees.

On the most recent instalment of Smarter Every Day, Destin explained to a crowd of industry insiders and policymakers why they needed to read SP-287 What Made Apollo a Success?. I was interested to read it as well, but the source was a scanned PDF and HTML. I have translated the text into an eBook for easier access for everyone.
