I'm 8 minutes into this video, and I'm thinking, "was this video sponsored by PPG?"

[@Palmit_]

nah. already got it, thanks. a lot of us do. also many vpns. for a clever channel. you're a bit silly taking sponsorship from an already massively saturated marketing marketer. you'll reach about 0.061% of the population that haven't got it or haven't heard of it already. do educate us with your sponsorship earnings and uptake. just for science sakes.

@@johnpats7024 yes. thats what i want to know as well. how much has each channel earned. and how much has youtube earned from their own ad's etc. the only way to be sure is get an accurate question, answered with an accurate answer. How's your research going?

[@andersjjensen]

"The scrap bin of fascinating things that don't make for an entire episode on their own" needs to be a recurring theme. I love the presentation style of this channel, and I'm often marveled at the research, script and production quality. I understand it takes an awful lot of time to do the feature length ones, so I'll happily take these "Charcuterie board" style videos if that means more episodes.

Thanks, very needed

[@MeneGR]

The real MVP!

[@NickNam3]

When designing a 3D printed height extender for my coffee table i encountered the problem where the pole of the table has to be tight fit in the extender. Doing this the extender would brake no matter how thick i made it, probably because the internal stresses where so big because of the tight fit of the table pole. By simply adding very small grooves in the extender the material has somewhere to go and there are no internal stresses. So simple yet soo important. Very intresting!

[@fricki1997]

A similar trick is to "feather" the hole, i.e. replace the simple circular circumference with a large number or angled rectangles (look up featherboard on Google, and then just imagine that going around a circle), it makes for a tight fit without the need for exact print dimensions. By varying the length of the feathers you can also vary the force applied, or how easy it is to install on the pole. I also read it's good for connections that often have to be pulled in and out.

[@NickNam3]

Materials science is the most qualitatively interesting field of science, but the most quantitatively is the most mathematically obtuse field of science. I’ll stick to my E&M.

[@adrianr5318]

Do you mean that materials science, from a quantitative point of view, is one of the most mathematically challenging fields out there?

[@Scrogan]

@ sorta, yes. At least among the practical fields, string theorists need not apply. The important part is the disconnect between simple mechanical laws that we determine empirically, and the complex nature behind how we think those laws actually arise from the condensed matter physics. Condensed matter physics is home to a decent amount of unsolved problems, gives rise to some unintuitive elements, uses conceptually difficult mathematics, and is computationally intensive. To be frank though, I barely passed condensed matter, and did so without understanding what Dirac notation is.

Curie point heating: The initial example showed it used with induction heating. But I have a soldering iron that uses conventional resistive heating (like your electric space heater) but the curie point operates a switch, that interrupts the electric current going thru the heating element.

I prefer hidden engineering failures. Like how engineers always put 2 inch bolts in places that when assembled, have only 1 inch of clearance. Or a bolt designed for a wrench to torque it to be recessed so a wrench can't interface with it........ there's countless more examples, but they're even more infuriating than hidden successes.

[@wellscampbell9858]

Regarding the curie point heating, some of the engineering overlaps with induction heating; the heat is generated by eddy currents which circulate in the work-piece. Higher frequencies concentrate the heating closer to the surface due to the skin effect. As the Curie point is reached there is a definite change of load, however if the power supply accommodates for that, heating can continue far beyond. The currents generate forces that oppose currents in the coil, so if your coil is cone-shaped, the steel can be made to levitate. One of the science-based YT creators (Mark Rober? Backyard Scientist? can't remember...) has a video where the levitating liquid ball of steel begins to BOIL!

[@dianapennepacker6854]

Try to get some mescaline aka Microdots if you guys haven't.. Better than acid in terms of spiritual tripping in my opinion. Like a cross between shrooms, acid, and MDMA. My friends who took more since I was broke cried at seeing headlights. Hardcore skater punks. Mescaline is derived from the peyote cactus. They are called buttons, and I could never actually get my hands on just any buttons. Nor could I ever get mescaline again. Yet online has changed that. My friend looked, and it was quite expensive at something like 70$ a micro dot. (That is the slang name of mescaline as they look like a tiny seed. A sesame seed to be exact.) Great stuff. For some reason I am reminded of the story of how X guy was pulled over by the cops with hundreds of tabs of acid. Put it under his arm pits. Ended up perma tripping? You guys ever been told that story. My sister says she knew a guy who did the same thing. I think she heard the story and lied.

[@timbehrens9678]

I am really curious about the frit points transparent for lidars. I am also not aware about those being of any relevance for radars.

[@kindlin]

I couldn't find any mention of fritting related to glass thermal stresses. They are there to reduce the amount of sunlight that enter the car, to reduce glare and improve comfort. EDIT: Through some additional targeted googling, I did find references to this affect, but I'm not sure it's the main purpose, and I'm surprised the most commonly known use of the frits was not mentioned.

[@Atmatan]

Couldn't TEGs be used in something like electric bicycles to act as an alternator for recharging via pedaling? Not sure why it seems like no one is exploring that..

[@mfbfreak]

First, be aware that TEG is the abbreviation of a Thermo-Electric Generator, most commonly made with peltier/seebeck modules. Those are awesome in itself - you can mount a few on a big heat sink and then charge a phone on the heat output of an oil lamp, or augmen the light output of said lamp by running a 1w LED on one. The LED will outshine the oil lamp by a lot. But triboelectric generators don't even come close to generating enough power to supply consumer electronics and proper lighting. What we now have (conventional brushless generators within the front wheel hub) is perfectly good for that. Those are high efficiency with low parasitic drag if not in use. Every conventional city and trekking bike uses those today, only the folks who really care about shaving off 500g and 3 watts of power drain don't use them. Bottle dynamos are deprecated.

[@Atmatan]

​@@mfbfreak So much of this is just plain incorrect that I don't know where to start. First off: NO bike uses a front hub motor, ever. They either use an axle motor at the pedals or a read hub motor: A front motor would send you over the handlebars and be unbreakable using conventional wheel breaks: Meaning all cheap bikes would be forced to use disk breaks, something they obviously don't do. Also: The only limit to the amount of power generation a TEG can output is the amount of friction viable between its supporting materials: I literally watched the video, mate, which you clearly didn't manage: All of this was well explained. I can find a 50 watt TEG right now from tegmart used in wood stoves that will output MORE power than my current e bike is even capable of taking in through ac, and that's just the first result on search, took no effort to find at all. You know drones were deprecated in 1967 but here we are reinventing the wheel again. If you''re going to argue viability, at least comprehend historical prescendent.

I hate to burst your frit bubble, but you showed many front windows for cars while explaining the fritting process.

[@dianapennepacker6854]

Yeah maybe he can break it down into chapters. Make them more relatable to each other. I also still don't understand auxetic materials. They have gaps, and compress, and come together. Seems pretty logical to me. I don't see how that makes a material thicker. Like saying when my house collapses it becomes stronger/thicker as you can only crush it so much. Only these rebound back to shape. The total dimensions don't get thicker, and still compress.

[@mouserr]

starting off by informing viewers of the forced commercial theyll have to sit through that ignore adblockers earned you the record for shortest watch time of any vid added to the do not recommend list at a stunning 3 seconds. hope that sponsor commercial was worth it and i hope more peopee start skipping vids over this kind of bs. youtube specifically told everyone it wasnt their job to protect users from malicious ads 'if it bothers you so much use an adblocker' they said dismissively and here you are bypassing those adblocks forcing commercial on users. many of which are if not scams, often promote illegal activities or is youtube fine promoting piracy via vpn. guess they dont mind piracy if it keeps traffic coming and you dont care if you chase off a viewer or 10 because 100s will not ensuring you get your sponsor money and youtube adcash.

I don't go around correcting every person, but engineering is supposed to be precise and requires precise language. I have a hard time taking someone seriously when they talk about engineering traditions. Traditions like what? Singing the Walmart song, sacrificing a baby goat, or just assuming people will understand you even if you use incorrect language. And I hope you are well also.
