😁👍👍 I understand your point about striking a star/planet for an "incident" - "horizontal column comparison to mountains/edge of visible universe...-? But in the overall Aggregate ("assuming evenly distributed" universe mass) the concept/horizontal Column...is inclusive of those stars/planets... Just for clarity.. - The actual "space" of Space (low overall matter density) is very, VERY profound..👍👍 Excellent comparison/visualization aid! TY!
Honestly this just somehow brought back memories from when I was still a kid watching these videos. You're a treasure for humanity Cody, never stop showing us your knowledge.
Same, I kinda put Cody and Mythbusters in the camp that turned me into a stem minded kid. Even now as a boring video editor, I still experiment, explore and learn things just cuz knowledge is fun.
Any other large RU-vidr would have animated those totes stacked... He asked us to use our imagination, that's totally reasonable! More relatable as well.
whenever I see a new Cody's Lab upload, I remember my fresh out of HS days. Physics undergrad dropout working in the bakery and showing up late on saturday because I stayed up until 11pm watching Beekeeping and random science vids on this very channel. That was almost a decade ago. glad this channel is still going.
Atmospheric Pressure is ~1 bar. 1 bar is ~1 kg/cm² 1 kg/cm² is 10 000 kg/m² 10 000 kg is 10 tons 10 tons is ~10 full IBC containers. It's nice when math is that easy.
i say this with absolute sincerity, i adore the use of "two and a bit" as a measurement. not all sciencey questions need exact answers, not everything needs to be precise. i know it's a small thing overall, but imprecise estimates have their place, and deserve respect when properly applied. been subbed for a long while, thanks for the consistent quality throughout 💜
@@MWB2Bleachfan These science/math communicator type of channels are better at it than most teachers, only because the visualizations seem to be much better. 2Blue1Brown, Tom Scott, Vihart, Periodic Videos, Numberphile... stuff like these channels should be used in classrooms honestly.
Man I hadn’t seen a Cody’s lab video in years. But this was amazing. I felt like I was getting a lecture from my uncle who was a phd in physics and he would ramble on about stuff like this sometimes. R.I.P. Uncle Mel And thanks Cody
A minor correction around 5:00: because the bottom surface of the fiber board is slightly lower, it actually experiences a slightly higher pressure, so there is a slight net force (upwards). If you work out how much this force is, it turns out to be buoyancy.
What's really fun is that with most cell phones you can measure atmospheric pressure carefully enough to see the difference across a couple of meters of vertical change. You can easily map what your phone shows to a finer scale and do the actual measurement to show that (deltaP)(Area) = buoyancy.
This effect also works on human bodies. The weight shown on your scales is LOW by a little bit - about 80-100 grams or 3-4 ounces to use very 'round' numbers.
nice, also puts into perspective what those guys in the titan submersible were under. 3km+ of water above them, and normal air is only several meters worth of water.
Even more astonishing is that they bragged about being a "diverse" company and they couldn't figure out something some simple as the math involved at those depths. It isn't a new field of science. How could they not figure that out? Diversity.
@@KainYusanagi 0.4 psi per foot of depth. (I can't be bothered to convert that to metric because kPa is an ugly unit) Now multiply by 10,000 feet of depth.
That fact about the mass between you and your neighbor compared to you and the edge of our observable universe is absolutely mind blowing. Never stop making videos :,)
Also, I know it sounds dumb but why EXACTLY does it take so much more energy to say move something vertically into space versus diagonally through air. Is it purely just the work required to fight against the vector of gravity for such a long distance? The obvious example I mean is a rocket; as I’ve already been told before, that the biggest thing a rocket fights against is air resistance. But then how efficient would it be if something can be sent straight up if it’s only meeting air resistance equivalent to the mass of that much water… Maybe Cody should just start a literal rocket science series for us.
@@oreodog My quick stab is that the air resistance is such a problem because the rocket needs to exit quickly. Think of it like moving through water quickly vs. slowly; resistance increases drastically with speed. It needs to exit quickly because gravitational force is persistent (as opposed to air resistance which is in response to motion), therefore the longer it takes to overcome that force, the more energy will be required to overcome it. Since gravitational force decreases with distance/altitude (modeled by the inverse square law), the faster you get further, the less overall energy is required. Since that energy is stored in a massive amount of weight (rocket fuel & associated boosters), more required energy consumption means more weight, which means more required energy again to generate lift for that weight, as a sort of vicious cycle that eventually makes escape impossible below some particular speed/time/acceleration threshold.
@@oreodog drag is proportional to the _square_ of velocity and rockets have to move very fast to fight gravity. The resistance a rocket encounters isn't actually equivalent or proportional to the mass in those water tanks
I "Think" he's in Utah. Pretty sparse living out there. For Instance, Daggett County, Utah is the least populated county in Utah, with a population of 1,029 as of 2023. Daggett County is located in the northeastern corner of Utah, bordered by Wyoming and Colorado. The county has a total area of 721 square miles (1,870 km2), of which 697 square miles (1,810 km2) is land and 24 square miles (62 km2) (3.3%) is water. It is the fourth-smallest county in Utah by area.
@@tbird81 Yes, I know. Here in Italy it is still pretty much unheard of to have _the closest neighbour_ be 10km away. In fact in continental Italy I'd be surprised if you can find a single point that is 10km away from a whole _village. Maybe_ you can find some in Sardegna.
This channel is one of the few remaining on youtube with raw passion for just sharing cool stuff. Cody, you're one of the golden gods of youtube for me, and I'm very grateful you keep doing what you do. You're awesome man, merry christmas and happy new year from Warsaw, Poland!
Thanks Cody! What struck me the most was how much little carbon there is on the earths surface. Plants seem to be an integral part of capturing it from the air and locking it into the soil. Then it can be used by other life forms! Mind blown!
Well yeah. Soil did not and could not exist without plants as their roots trap clay particles. Without plants, you would have only sand and rocks on land and rivers could not form.
Maybe that's why my cat follows me around so much: she's trying to ensure that, no matter which of Earth's square metres I occupy, there's always a cat in it :)
and there's an ant for every square millimetre on earth. oh and before someone asks "why isn't the whole world covered in ants?" 1. it is. 2. 3d space exists. the world is not a 2d plane.
This has the same energy as when I think about the fact that the moon and planets and stars are just objects out there. That's why you can see them, is because they're _right there._ I look at Jupiter through a telescope and think it looks pretty, and it's hard to really comprehend that the reason I can see it is because it's _right there._ Just like my neighbor's house, only a bit farther away, and unfathomably big. And the same is true of stars-I can point at Albireo and say "look how pretty that is" because they're _right there, right where I'm pointing._ And they're so far away that I'll have lived and died and been dead for hundreds of years before a photon bouncing off of my pointing finger ever reaches them, and they're so big and bright that I can still see them despite that. And it's crazy to think that those photons will have to go through more matter within 100 miles of me than the entire rest of their journey to Albireo combined
I understand completely. This thought leads me in so many different directions. Gravity and the laws of motion, and the history of collisions between objects, are all such that the Moon exists - a rock big enough to be its own world. A world which could collide with ours, but due to luck, hasn't so far. The moon is orbiting so close that we can see its surface features and the only thing fundamentally stopping us from travelling and staying there is not mathematics, physics, or chemistry, but economy and common sense. Our lives are so stable and serious, and we care about who's next to wear the big politician hat, and we have soap operas. However, all the time there's just a bloody giant rock spinning around us in a circle, and because of work and distractions, barely anyone stops and meditates about the implications for very long. It's the same vibe as looking at the sun briefly, and appreciating that the reason you can't look for longer is because you're literally looking at nuclear fission.
As I've posted elsewhere before- The greatest problem with closed ecologies is the inevitable amputation of the atmosphere. In the open on Earth, a square meter of good farmland extends at least 30 cm into the surface and has a mass close to a ton, with perhaps 10 to 50 kg of water available. But the air on top of it outweighs everything else at ten tons. Putting a dome generously ten meters above the soil leaves at most twelve *kilograms* of air, nowhere near enough to buffer the daily flows of water, water vapor, CO2, and oxygen that must flow in and out of the soil and plants. All the ills of ECLSS stem from this desperately limited air supply. For example, those ten cubic meters of air, at 400 ppm CO2, contain a whopping seven grams of CO2. The enclosed ecosystem is balanced on a knife edge. Any off-earth closed ecosystem will need a good buffer for oxygen, CO2, and nitrogen. All three gases must be able to be drawn from and returned to storage as the biosystems fluctuate in throughput due to seasonal and (on Mars) weather changes.
Cody, your explanation brought me a vivid imagining of the Earth inside a reaction vessel, undergoing hydrogen "distillation" with carbon as a catalyst. Very wonderful, thank you. Cheers to you in the dark time
love your videos man, been watching em for years now you had part in shaping me, not to a great extend but a positive difference. I wish you best of luck on your endeavours, CH base looks promising too :)
I thought the same thing, although the caveat there is that you generally go diving in salt water (which is why he needed the extra 300L of water I guess)
I did not expect my mind blown by an upload from Cody today, yet here I am and all the better for it! Thank You for staying around and staying as fascinating and informative as always!
Thanks for the holiday upload! The wonder of the natural world articulated thoughtfully and engagingly by way of some really mind blowing examples is always a treat on your channel. Your dedication to your craft(s) continues to inspire.
When I was a kid who loved science living in the rural west I always imagined doing stuff like you're actually doing. Seeing things like you do actually happen scratches an itch I've had forever. You're a special critter, man! Thanks for doing what you do.
Ur content is very fun to watch. I love what you have done with it and it has made me very happy over the years. I appreciate you and hope that you prosper and achieve ur goals.
I imagine when most people would see this video, that would just scream "Nerd!!" But if it wasn't for people like Cody in the past, we would still be chiselling into the stone. It reminds me the videos when I first stumble upon this channel. Loved it!
Thank you for making this video. It paints a really cool view in a multitude of perspectives. I really appreciate you bringing out something akin to a child-like wonder in myself and so many of your other viewers.
This is such a pure and entertaining channel, I love it. It makes me feel like a kid again, asking the simply interesting questions and really digging into the answers
I envy the view you have from your base. 10 km or even more distance clearly seen from that point. Far away mountains, blue sky, it's simply beautiful. So grand and serene.
Did you get a recent iPhone for filming? When you zoomed it changed the microphone and your voice got quiet. I saw a video from dankpods about the new iPhones and this is something he complained about. He also had a few tips on bad default settings that he changed.
Hi, I really enjoyed that visual comparison. Your visibility up in the mointains is incredible too. I am surrounded by hills and forests and can hardly look further than 20 kilometers, more often closer to four. Also if you filmed this recently I really appreciate the amount of sun you get in mid winter, it's been a deplorable mess of thick clouds and rain here for weeks. Thanks for posting, cheers from gloomy mid-northern Germany
This was alarmingly fascinating! It's good to know that if every tree were to spontaneously combust we wouldn't suffocate! I'd love to see you explore the environmental impact of it though!
yes - you can easily breathe the atmosphere if you burn all carbon, but you will still feel the greenhouse effect practically cooking the earth at the same time.
