The use of the “Wilhelm Scream” was priceless! I actually laughed out loud… I am a post production sound designer/mixer, and the Wilhelm Scream joke has been so overused it’s actually become funny again, mostly just due to how out of hand it has become with every sound designer I know trying to slip a Wilhelm Scream by the supervisor/director, and clients… I’ve snuck Wilhelm Screams into just about every type of sound effect you could imagine! For a period of time I was working overtime, and sadly getting burnt out working long hours recording/sound designing/mixing, mostly TV commercials. To keep myself going, I ended up entertaining myself by sneaking in at least one Wilhelm Scream into every TV and/or Radio advertisement I worked on. Eventually my coworkers all did the same, and we had a competition based on how many Wilhelm Screams we could get by all levels of approval, and finally aired on TV/Radio. I still laugh about all the silly ways we incorporated the Wilhelm Scream into the sound design! The best ones were the inappropriately used screams, some I still have no idea how they went unnoticed by both the bosses and clients! Thank you for giving me a good laugh remembering those silly times! 🙃 hahaha!

We had solar hot water on our house back in the 70's. It actually got a write-up in Family Handyman. Worked great... In the dead of winter, on a cloudy day, water would still come down from the roof at around 100F. In the summertime it was more like 190F. And this was just north of NYC. And, with a total of 165 gallons of storage capacity, there was no such things as running out of hot water.

As huge as Tsar Bomba was, it was actually only HALF as powerful as originally designed. The designers realized that the aircraft would be unable to outrun the shockwave, so they decided to replace the uranium tamper with a lead tamper, resulting in roughly half the resulting energy production. The design was originally for double the energy.

I don't do podcasts often I would love for you to post them here, or in a new channel. I actually enjoy looking at audio visualizers while listening.

Here's a video suggestion: this is sort of in line with the Hungatonga thing from today's video, as well as your supervolcano apocalypse video from a while back. I suggest you do a video on the 1902 eruption of Mt. Pelee on the Caribbean island of Martinique. The reason is because when you talk about volcano disaster porn, there's only one cataclysmic eruption of a volcano, powerful enough to erase a city of 30000 people off the face of the Earth, for which we have actual photographic documentary evidence. You can talk about things like the eruption of Vesuvius and the obliteration of Pompeii, and other eruptions like the Ilopango eruption in the Americas that maybe ended Mayan civilization, but for most people the actual extent of the horror will never fully hit home because pictures of people scratching for evidence in the dirt will never have the impact of visuals of the catastrophe itself. When I took an until-then boring as dirt geology class in college (it was an elective) I was bored to tears until we got the part concerning volcanoes. Then it got downright horrifying and awe/dread inspiring. People hear that residents of Pompeii died mostly as a result of getting hit by superheated gas and particulate matter from a pyroclastic flow and, I think most people react to that with "uh, hunh?" And probably imagine the poor people gasping as they suffocate on dust-clogged air from the eruption. No, it was much worse than that. Which is fortunate as the dead of Pompeii and Herculaneum probably died instantly when the pyroclastic flow hit them, instead of slowly strangling them through asphyxiation or boiling them alive which is what used the be the story of how that went. The only contemporary thing comparable to the damage from a pyroclastic flow would be an atomic explosion. And of this particular horrific phenomenon, we have extensive photographic evidence of exactly one event, the eruption of Mt. Pelee. The city of St. Pierre was known as the "Paris of the Caribbean" because of how beautiful and cosmopolitan it was. When the volcano Mt. Pelee ("Bald Mountain") erupted, it belched out a superheated pyroclastic flow, also known in geology as a _nuee ardente_ or "glowing cloud" because, well, if you see it at night it glows eerily because of the temperature being somewhere around 2000 degrees. This pyroclastic flow was heavier than air and flowed downhill and enveloped St. Pierre and incinerated it to the point that not even ash was left. This is no exaggeration. Not even Hiroshima or Nagasaki were so completely erased by the atomic bombs as St. Pierre was by Mt. Pelee. Additional details might help you understand: Of the 30000 residents of St. Pierre, only one (yep one) human survived. The rest were killed instantly. The sole survivor was the local town drunk and bully who was in what passed as the local jail lockup, a bunker that used to be what's referred to as a "powder magazine" or place where gunpowder and explosives were stored, an extremely dense and fortified enclosure as you might imagine as it would have to contain the explosion if all that stuff lit off at once. The man who was in it was burned horribly but he did live. He was the only one. Everybody else, along with every dog, cat, goat, bird, snake, cow, horse and anything else larger than a bacteria simply ceased to exist, instantly flashed into products of combustion. It gets worse. St. Pierre was founded, as you might imagine for a Caribbean colonial town, on a nice natural harbor that was on that day filled with ships. People on those ships likely watched in horror as the entire city was instantly obliterated. No doubt that horror intensified when the _nuee ardente_ hit the water's edge and kept flowing over the surface of the water to the ships. Every ship in the harbor was burned to the waterline. People who tried to escape by jumping in the water were killed when the entire harbor began to boil. No crew on a ship in the harbor that day survived. The only witnesses to escape were the fortunate crew of a few ships who'd headed out of the harbor early enough to have a little more distance between them and the volcano. Many of them were scorched and the crew horribly burned but enough survived to carry the story away from the island with them. So yeah. The reason it'd make an interesting video is because happening as it did at the turn of the 20th century there's plenty of before-pictures of the lovely, picturesque city of St. Pierre and its inhabitants. And also plenty of pictures of what it looked like afterward. Which is essentially a moonscape cluttered with random rubble not even identifiable as parts of what used to be structures in a vibrant town populated by human beings. Look it up. It literally has to be seen to be believed. The destruction is absolute. If you'd dropped a "Fat Man" atomic bomb on St. Pierre, there might have been much more of it surviving afterwards. I guarantee you'd get a bunch of views on the video if you make it because of the extensive photographic documentation. I for one would sure like to see a proper Joe treatment done on it even if it is just fifteen minutes long.

Classic KISS principle. Keep it simple stupid.

For most of those cultures, each knuckle/phalanx has a specific assigned value. Base 10 probably won the popularity contest because it doesn't need a higher level of indoctrination to understand "how many fingers am I holding up?" versus "what's the value that our culture has assigned to the knuckle am I indicating?" 7:55 I thought you were about to recite the refrain of a Prong song, "Snap Your Fingers, Snap Your Neck." 🤟

@@dave900575 What you've demonstrated is that base 10 math is the ideal way to do operations on our decimal (AKA base 10) Arabic numerals. If a base 12 culture developed a numeral system, it would likely iterate after every 12 cycles instead of 10 like ours. That culture would be more concerned with factors of 12 than factors of 10. There's nothing magic about "10" in and of itself except in base 10. In base 12, "12" is the magic number that makes division/multiplication easy. Taking it out of the hypothetical: The hardware in electronics communicates via binary (base 2). Binary-to-decimal conversions get cumbersome for humans, so hexadecimal (AKA hex, base 16) was created to make the human interaction easier when programming/debugging, plus it's a great compression of binary (1 hex character encodes 4 binary bits). Hex uses the "numerals" 0-F (0-9h represents 0-9d and A-Fh represents 10-15d [h for hex, d for decimal]), so that the digits iterate after every 16 cycles. Doing operations in base 16 becomes second nature fairly easily because of how the hex numerals iterate. To bring it back to your question: What's the advantage of using a different base? It all depends on what you're trying to do/communicate and with whom/what.

Just my two cents :D

Great video as usual, but your explanation of wing lift was incomplete. We used to think that wing lift did indeed come only from the difference in pressure between the top and bottom airflow. It turns out that vortices form at the wing edges and that is what creates the majority of the lift. When those vortices spill off the end of the wing it causes drag, which is why you see small vertical winglets at the end of the wings on most commercial aircraft.

Hold on, while I agree Joe's description was somewhat incomplete, the explanation provided here is definitely wrong, at least for conventional wings (see my note at the end of this post). Forgive how annoyingly "well, actually" my comment might seem, hopefully it contains some interesting insights into the complex silliness of everyday fluid dynamics. For a bit of credentials, I did my phd in computational fluid dynamics studying aeroelastic flutter and vortex shedding, and now work at nasa as a multiphase fluid dynamicist and spacecraft propulsion expert. Again, apologies for this "you're explaining lift wrong" rant, I think it is a weakness that many fluid dynamicists share. When we see lift being explained incorrectly we are compelled to unnecessarily intervene. I agree Joe's explanation was somewhat incomplete. It isn't really fair to say lift is "caused" by pressure differences. It's more like pressure differences are evidence that lift must be occurring. Pressure differences on two sides of a body immersed in a fluid by definition create a force, but that is just a tautology not a root cause explanation. Similarly, velocity differences between the upper and lower surface also don't "cause" lift, they too are evidence that lift must be occurring (as they imply a pressure difference). What actually causes lift is complex, but in my opinion it is understandable to a lay audience. My preferred way of describing lift is to think of it as the result of "flow turning", which I think provides a nicely intuitive and accessible explanation: As a fluid passes over a wing, the wing is shaped and/or angled in such a way that the flow is "turned" from going straight when it first encounters the wing, to going at a slightly downward angle after leaving the trailing edge of the wing. Because the moving fluid has momentum, if you turned it from going straight to going slightly downwards then you must have changed it's momentum, meaning you must now feel a force pointing upwards (because momentum is conserved). You could then ask "how does a wing turn the flow", which is a good question with different answers for different types of wings. But for most conventional wings (and for flat plates, or even your hand out a car window for that matter) it is a combination of two things: the angle of attack redirecting the flow on the bottom side of the wing downwards (a relatively minor contributor to the flow turning), and the flow on the top surface of the wing trying to "stick" to the top surface even as it drops away due to it's curved shape and/or angle (i.e. it remains attached despite the curvature/angle, creating an adverse pressure gradient), which is by far the larger contributor of the two. As you increase the angle of attack of a wing, the bottom surface is angled more downwards compared to the incoming wind direction (a minor contributor), and the top surface also "drops away" more dramatically (the major contributor), both of which increases the lift. I like this explanation because contained within this accessible (imo), jargon-free description is actually all of the complex fluid dynamics that is really underlying the flow turning and lift. For example, Navier-Stokes is represented insofar as the root cause is ultimately ascribed to momentum conservation which is exactly the components of Navier-Stokes which are relevant in this circumstance. Or, if you prefer a more old-school potential flow type perspective, this explanation is completely consistent (in fact it's synonymous) with the classic "lift is due to circulation enforced by the Kutta Condition at the trailing edge" explanation, because "flow turning" and "potential flow circulation" are really saying the same thing. Also, armed with this explanation, you can intuitively understand how stall happens (the flow stops sticking to the top surface), how wings can fly upside down (you just have to angle them more so the net flow turning is still towards the ground), and indeed why most commercial planes have winglets these days. Without those winglets, the pressure difference caused by the flow turning (really caused by the angle/curvature of the upper surface creating an adverse pressure gradient, which is the same thing) wants to equalize by driving flow somewhat towards the wingtip as that is where the high pressure underside can leak to the low pressure topside. That flow in the direction of the wingtip (in the so called "spanwise" direction), does create wing-tip vortices which are parasitic, but it also takes away some of the potency of the airfoils' flow-turning abilities, both of which decrease the lift-to-drag ratio. If you can stop that spanwise flow by not allowing the pressure fields to leak, then you can keep the flow best aligned with the wing's cross-section, allowing the maximum flow turning for the least drag. As I mentioned at the beginning of this rant, your explanation is actually somewhat correct in a very specific scenario, which is delta wings. Mind you, it has to be a full delta, and it has to be subsonic. Swept wings work based on the exact same principle I described above. And supersonic wings work by a totally different mechanism entirely (which is also super cool, but not relevant here). But for a subsonic delta wing, while there is still a minor component of the lift that comes from the flow-turning mechanism I described above (delta wings can still use airfoils as cross-sections), the majority of the lift is created by very large "attached" or "stationary" vortices that develop on the upper surface along the swept back leading edge. All vortices have a low pressure region at their core, so by attaching a permanent low pressure region on the top of your wing, then you get to bypass the need for flow-turning and skip straight to the lift. You also get a bunch of drag as a penalty, but other aspects of a delta wing balance it out to make it ok for subsonic flight. In this context, the roles are somewhat reversed in that if you measured the flow before and after the wing you would of course still see flow-turning (after all, to get lift momentum must have been transferred), but now it should be considered as evidence that lift must have happened, which happened due to an induced pressure difference created by attached vortices. Once again, apologies for this very long-winded diatribe. What you said wasn't bad, but I guess for me seeing someone correct a sorta wrong explanation with an even worse explanation apparently triggers a strong "well, actually" response in me.

@@SapientPearwood awesome info, thank you for taking the time to share your knowledge! This pilot and mechanical engineer enjoyed reading it. I've seen "down wash" used to refer to the flow turning you explained, but maybe that's a bit of pilot jargon and wouldn't be understood as easily by a general audience.

I'd love to see a whole video on "craziest oceanic creatures and their crazy abilities." And as far as "energy sources" go, while it's nowhere NEAR feasible yet, I'd love to see a video on antimatter reactors (like the Warp Cores from Star Trek.)

But anti-matter really isn't an energy source, it's a compact hypergolic fuel that needs to be synthesised using truly absurd quantities of energy. Unless of course we find antimatter dust floating in deep space that can be [safely] harvested, then it would be a net energy gain from out perspective.

Joe I’m SUPPPPER interested in bringing your podcast to KZread, as weird as it sounds I listen to ur vids when I go to sleep because my mom who died about a year ago now would sit up with me in bed and we’d watch all of ur fascinating topics so having basically hours of u talking is pretty damn cool as weird as that might be lmao

I just watched the episode you had on pistol shrimp and then the underwater eruption . Funny stuff. You should most definitely air your podcasts. Your insight and storytelling are great to watch

TOTALLY love to Check the Podcast here on KZread!

Can you talk about how farms have a severe lack of diversity in food and how they use insane amounts of water and chemicals. Like earth has 100,000 edible plants on it mybe more.

I once made a program on a calculator to convert everything to base pi. It was kinda weird. Personally I think base 16 makes more sense considering how ubiquitous hexadecimal is with computers. For heating applications, active solar + a heat pump is way more expensive and a bit less efficient than passive solar. I'm looking at ways to add passive to my system. If I can get some of that 80% energy heat loss from my active panels... I would prefer a podcast that is posted on youtube so I don't need to figure out another media platform. That shouldn't dissuade you from posting it on other media platforms as well.

Hex is merely a convenient representation for humans that maps tidily onto base 2, the numerical system of digital computers. If we could make reliable computers that operate in base 10 we probably would, unfortunately that is not the case at the moment.

Hex (and oct and binary) are sort of the opposite logic to base 12. The former are only divisible by powers of 2... Easy for simple mechanical/algorithmic systems. But 12 is 2,3,4,6, which gives more shortcuts for doing arithmetic in your head or with complex algorithms.

I say yes to the channel for your podcast. I follow you from Rome, english is my third language and for me the subtitles are very usefull to fully understand the contents.

7:20 actually, actual sound has a limit. The pressure of gas is dependent on the number of gas particles in an inclosed space. and _Sound is a Pressure Wave. Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving._ Because pressure waves theoretically are double the atmospheric pressure at the highest and perfect vacuum vacuum at the lowest. Because unlike charge, there is no negative pressure, only a prefect vacuum. Which is known as a shock wave. _ Strictly speaking, the loudest possible sound in air, is 194 dB. The “loudness” of the sound is dictated by how large the amplitude of the waves is compared to ambient air pressure._ Well I had an interesting read I got to say.

Watching this video as Russia invades Ukraine lets hope we wont see another Tsar Bomb

17:00 the misses and I with 5 more friends went to San Juan in June. It was amazing.

The Pinatubo's SO2 emissions had some longer lasting effects on the global climate, not just a few days: The cooling aerosols caused an average temperature drop of about 0.6 C for 15 months (says NASA). And it even caused some changes in the hydrological cycle (precipitation and river runoff) for about a year or so.

Yes, more Joe on KZread is ALWAYS a good thing.

You can actually count the subdivisions of your fingers with your thumb to get to to twelve (3*4) If you use your second hand to count how many times you got to twelve by raising the appropriate finger you get 60. That's where base 60 comes from.

Yo what’s up, Joe? Loyal subscriber here, love your stuff. As for your query on podcasts for KZread, personally, I’d love it if you posted them here on a second channel. Also, I would like to make a recommendation for these podcasts as well… if you could edit some of the episodes down to clips that could be posted as KZread shorts… That’d be awesome. Personally, to get invested in a long form podcast, I need a trailer, you know?

On base 12 and body parts: If you count the number of segments on non thumb fingers on one hand you get to 12, it sounds more complicated than it is but it’s really convenient to count that way because one hand does the counting and the other does the pointing.

Yo Joe love your channel. Been watching you for 2 years..
