Hero of Alexandria is remembered for his iconic work on geometry, Metrica, which was lost for many years but was then discovered after 1896. His most significant contributions include the Heron’s formula to find the area of a triangle, the Hero engine, and a wind-harnessing machine.
Imagine any low but major production becoming constant, consistent and not relied on human/animal labor, 2000 years ago. The standard would be out of this world compared to anything else. I think that is something extremely taken for granted, just how good even our worst products are made, because we can replicate the motions, via machines to exacting measurements, over and over and over and over.
"You need one of those wired devices that are used to close garbage bags" is a really long way to say "twist tie" Edit: just remembered they are also called "wire ties" especially if they are the kind without the paper on them.
A good question! Try it out by carefully watching the spout of a boiling kettle. Actually, when water boils, most of the dissolved material, such as food colouring, is left behind. If this were not the case, we would get purple rain, green steam, rainbow-coloured raindrops, etc etc . . . Deane.
I must've driven Mum nuts making all these kinds of contraptions and whatnot! But in the end I had a great appreciation for science, history and engineering.
Nothing to do with the mainstream media it is the internet who is dumbing down everybody so they'll become good little consumers . Using imaginary concepts like left and right to put everybody into groups so they can be controlled . And constantly telling everybody that everyone's out to get you so you better trust us which gets people spending money on phone credit
the angle of the steam create rotation, in theory you can have the holes anywhere and it would still cause an effect, the reason the holes are symmetrical is to demonstrate the full potential of the engine, this allows the can to spin with less effort.
Actually it is thought that the books he wrote were actually lectures that he presented at the great library of Alexandria in Egypt, which was probably similar to a university.
@@jasonbennett7002 The Watts steam engine also achieved a greater efficiency by adding a gearded mechanism on its valve and gears are a technology that traces back to the ancient greeks as well.
I built a Hero's steam engine that does 5400 RPM. (www.HeroSteamEngine.com with embedded TH-cam video). Thoughts about whether an aeolipile (Hero's steam engine) could have driven a car or train or do other useful work has been debated for a century or more. I decided to build one and measure its power output to settle the question. I calculated its theoretical efficiency at converting heat energy to mechanical energy and it was only about 1%. But when I built one I found that the efficiency was only 0.01%, possibly due to losses from friction and air resistance. The results are given in detail in the web site. Look it up to see video, photos, calculations, discussions and dispelling myths about Hero (Heron of Alexandria) himself.
What if you had already highly condensed and hot gas, say from the surface of Venus that you could channel? I imagine that would allow for a much more efficient energy conversion.
@@edwardlecore141 Yes you would expect a hotter, more dense gas to produce more thrust but the thrust would depend on the pressure in the surrounding atmosphere. I suspect that on a celestial body where this gas exists, the atmospheric pressure would have to be high to maintain the gas in that state. Then the gas would not escape from the jets of the Hero steam engine unless it was raised to an even higher temperature and pressure and there may not be much advantage in the end.
@@Evan-e-cent The engines would not be in that atmosphere but in a sub-terranean area of much lower pressure, and the engines would be used for domestic power consumption. I am writing a sci-fi novel featuring ancient Romans building such colonies of Venus, so I need to come up with a power system for their city. I figured hero engines could work, exploiting gravity and pumping in the atmosphere above and removing the need for wood, coal or anyone to feed it.
@@edwardlecore141 OK. I don't know why an underground location would have lower atmospheric pressure than above ground, but hey that's fiction! Who knows!
Hero studied ancient documents, so it is not sure to my mind that he actually 'invented' anything. What is interesting is that aside from the aeolipile toy, he also built musical instruments that were powered by wheels that drove pistons. So he knew about steam power, and he knew how to build a compressor (or engine) that used rotary motion to drive pistons to produce compressed air. Is there any doubt that somebody already knew how to make a working piston engine 2000 years ago? I am pretty sure that technology has been supressed for an extremely long time. No wonder they burned the library of Alexandria. The Romans must have been desperate to get the dark ages rolling.
Considering the reference materials he used were already ancient in his day, 2000 years ago, who knows what was really going on with technology many thousands of years ago? I bet the answers are out there, but I doubt we will hear about them any time soon.
Lots of presumption in your post muslims burned libraries as a rule genius hero's engine wasn't a toy the fact expertsbrainwaahed people into believing it had no practical purpose is part of the psyop.
Wow. Really didn’t know that steam power was first invented around the time of Christ! Could have produced healthy, tasty, crunchy cooked vegetables for the last supper🥦🥕
thank you for uploading this. I didn't see it when it originally aired 30yrs ago. I rarely ever missed an episode 👌🏼

These guys were the masters of explaining things simply!
The intro song 😂yes explain this to me like a child.

Imagine... Being mentioned still in 2024. He would be proud.

Great introductionary project to show the power of steam. I wonder if food colouring will affect the puffs of water droplets.
i doubt it will change the colour of the puffs

@@CuriosityShow It would rain saltwater if evaporation took all the chemicals.

Excellent - that was the idea, and I bet you ended up with confidence in being able to DO things - Rob
The second he said "You'll need an Adult to help you" I realized that 30 years of
dumbing down on MSM had taken their toll. 😕😭

Thank you. That helped me a lot for my invention. We are all one chain of actions and reactions
why did you need a can with two holes on the top?
the angle of the steam create rotation, in theory you can have the holes anywhere and it would still cause an effect, the reason the holes are symmetrical is to demonstrate the full potential of the engine, this allows the can to spin with less effort.
Used to watch this show
Had there been a university in those days, Hero for sure would have been the head of its engineering department.
Actually it is thought that the books he wrote were actually lectures that he presented at the great library of Alexandria in Egypt, which was probably similar to a university.
@@Evan-e-cent Wao, thats cool
Not sure of the commas in the wrong place there ?
I remember drinking deep spring mineral water from these push button cans

Wholesome af
just wondering if anyone knows what that "garbage closing tie" is actually called? does it have a name?
GREAT VIDEO DEANE! THNAKS AGAIN!
I believe they are called different things in different locations, but here in Canada, they are called twist-ties
@@Maninawig
Ah yes. Twist ties. Sound correct, I known I've heard of those here in the TrumpTopia.
Anyhow. Thanks for the reply
Twist-ties yes. Or doohickey
It was a wonderful time were we didn't need to have a label for every single thing it was just the thing that worked
With gas prices today, i m a bit sceptical if we would be enjoying it rotating for hours.
So, James Watt didn't invented steam engine?
@@jasonbennett7002 The Watts steam engine also achieved a greater efficiency by adding a gearded mechanism on its valve and gears are a technology that traces back to the ancient greeks as well.
It took me 20 hours to realize this was a kids show.
Really cool
Pretty sure it’s Heron not Hero
One mistake in 30 years that's not too bad

That sounds a lot better than what they actually had.
technically there is mention of it from 225bc, a long while before christ. Hero just gets the credit for making a big show of it
