I met Destin when he came in for lunch today. Really sweet guy, and even stopped to say goodbye to me before he left :)

What is the name of the company and product that is advertised on the videos for a remote desktop type application?

Hi,

Destin is the main reason why i flew from Europe for this eclipse. His video after the 2017 eclipse was so impactful that it changed my mind from "i would like to see one" to "i MUST see one". Also his video with dr. Telepun was very informative and got me even more excited. After seeing the eclipse i must say i'm super thankful, it was amazing and worth all the effort.

So i was waiting for the new video to show up, i know it takes time to edit and all. But after seeing new video about Vulcan rocket i'm afraid there might not be the eclipse video?

How was Destin able to get his first slow motion camera when they can cost upwards of $100,000? Saw a similar question on the slow mo guys sub Reddit so I’m curious.

Hey r/SmarterEveryDay, I'm a grad student from Philadelphia. My team and I are working on a project for a smart car app. We are creating a project for smart car driving safety.

Imagine you are driving a car, and you have many distractions in the driving experience
(Ex: Acceleration, Breaking, Infotainment system, etc, like driving safety) . So this project aims to solve all the distractions by providing feedback at the end of every drive.

Would this be beneficial to you? Give me your thoughts & opinions.

So hear me out. If you put food in a total vacuum, and some kind of sensor to detect odors, how long would it take? Would it travel at all since there’s no air? Would the heat of the freshly cooked food radiate enough to move the molecules?

Tune in later for random thoughts.

Also, I’d still love to see an experiment explaining why we don’t like when in a car, and the front windows are up, but the back windows aren’t. What is actually happening with the pressure that humans don’t like.

Ok I’m done. Time for a bbq wing fest. Go Trash Pandas.

The recent video has me thinking a lot more about space than I usually have. Relatively new to the channel and loving it! I have two questions I am hoping someone here can answer

1. Why do comets have tails? If there is no drag in space, what is pulling these particles off of the body of the comet?
2. This is more of a thought experiment maybe. If the ISS were launched today, what would be different about it. Pressurization/Canadarm variations. What would be the biggest difference I wonder?

Hey there, I'm a grad student involved in the Atmospheric Perturbations around Eclipse Path (APEP) NASA Sounding Rocket mission that will be launching three suborbital rockets during the total solar eclipse tomorrow/today (April 8th).

Due to the mission being associated with the eclipse, we got a lot more press coverage than normal for a sounding rocket. This was cool at first; we got on the front page of the local newspaper, and had articles in many major online media outlets. But after the initial press, we got picked up by conspiracy theorists. Since it was a NASA mission during the eclipse, clearly we must be up to something nefarious. The mission acronym also being related to Ancient Egyptian mythology didn't help our case either.

At first it was all good fun seeing what people were speculating about the true purpose of the mission. But then some theories conjectured that the rockets were collaborating with CERN to summon something to end the world, or that they would release biological weapons over eclipse-watchers, or were intended to cause mass psychosis. Truly crazy, but these were significant enough to cause the creation of fact check articles. On articles which included the mission team photo, the comments became vile and incredibly racist and sexist remarks were levied at particular members of the team. People were also wishing our rockets would blow up on the pad, or fall back down and take us out. Fortunately no one has been personally tracked down and harassed.

I shouldn't focus on it, but as these conspiracies have received millions of views and grown to platforms such as Tim Pool, Alex Jones and Infowars, and OANN it is hard not to, especially when I've also heard people in public discussing these theories. Hundreds of thousands of people have learned something about this project that I've worked on for years, and they responded with mocking, hate, and fear. The hate is based on misinformation from people trying to incite fear, but it still impacts me. As someone who tries to spread truth and curiosity it was incredibly heartbreaking to see these waves of comments steeped in misinformation and chosen ignorance about something that I was a part of. After we launch and nothing happens I'm sure the conspiracies will go away, but the mission still has been tainted because a lot of people learned about it, but were misinformed.

I just wanted to come here and share the mission where it would be appreciated in order to spread some truth and curiosity.

Our mission is intended to study the effects of the eclipse on the ionosphere; they are suborbital rockets that will reach a peak altitude of 370 km (±5km). We actually already launched these rockets for the last (annular) solar eclipse back in October 2023, and they were recovered and refurbished to fly again. They carry a full suite of instruments for ionospheric measurement designed and built almost entirely by undergraduate and graduate students at ERAU and Dartmouth. The rockets will make measurements of the plasma density, temperature, and potential, as well as electric and magnetic fields, neutral density and winds*. We also have ejectable sub payloads that will allow for simultaneous multi-point in-situ measurements. We'll also be deploying balloons to assess the state of the lower atmosphere, and we have a lot of ground support instruments as well.

The ionosphere is the name for the region of the upper atmosphere which has become ionized by the sun and formed a plasma (largely 70 - 600km). It allows for things like over-the-horizon radio because radio waves at certain frequencies will scatter off of it at different altitudes depending on the density, and it can impact satellite communications like GPS when there are disturbances at the right length scales. When the sun sets, the density of the plasma drops because it starts neutralizing itself (recombination). It never totally disappears because the sun rises again. When the eclipse passes by, it is a very sudden and localized shock of neutralizing and reionizing that prior data has shown can cause strong waves in the ionosphere. The processes behind these waves is not fully understood because it is very difficult to study these eclipse effects directly. Scientific balloons do not fly high enough, satellites cannot orbit low enough for very long, and you can't just launch rockets anywhere there is an eclipse. Ground-based instruments are great for the big picture, but the temporal and spatial resolutions achieved by a rocket launch are unmatched.

So when you are watching the eclipse, here's one more thing to think about! Check out the rocket livestream, or if you are in the delmarva area, look to the skies as the eclipse passes by. We should be launching around 2:37, 3:22, and 4:07pm, as long as wind conditions are safe.

AMA about this mission or sounding rockets in general, I love talking about this and it would help get my mind off the conspiracies as we complete the final preparations.

Stay curious.

I'll be visiting Huntsville for work for two weeks in late July. Recommendations of what to do on a budget on the evenings/weekends?

NASA was tasked with setting up a standard lunar time. I am trying to wrap my brain around it but there are so many different things that go into it. Gravity has a direct effect on time right? So time passes ever so slightly different on the moon than on earth or in space? A lunar day is like 24 hours and 50min because the moons spin is so slow. So would there be different time zones? How the heck is all this gonna work? I think i have smoke coming out of my ears from thinking about it.

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.
