5:46 "I don't believe in getting something for nothing"
Because that would violate the laws of thermodynamics and conservation of mass.
And what does that have to do with his comment?
Sure did :)
You're the one who didn't get the joke.
BestServedCold was making a joke about the line at 5:46 where the host is talking about giving credit for content to other providers. But in science circles, various laws of conservation are based on the premise that you don't get something for nothing. And as with most joke explanations, none of this is funny anymore.
BestServedCold it makes me think of the robot from interstellar. "how are we going to escape this black hole?" "the same way humans have always traveled: by leaving something behind."
Could you please do more materials science / metallurgy videos like this? This video was done extremely well!
Yeap have a lot planned. Steel is one. Nitinol is the one I am most excited for!
As a student in material engineering, I'm glad to finally see some nice content about this field popping up on youtube ;)
Im graduated 3y ago, how it is going?
@@ing.joelmanzino6439 the calculus is and phys is the biggest struggle for me. but its going...
Fun Fact: the top of the Washington Monument is capped with aluminum because it was so valuable at the time.
TheJaredtheJaredlong I thought it was copper tip

Aluminum because limeys with weird accents haven't dictated my variant of English since 1776. And while we're at it, it's defense not defence, cookies not biscuits, cilantro not coriander, eggplants not aubergines, parking lots not carparks, and able seaman is not and never had been a rank in the American navy and sounds really dirty.
I have a bachelors and a masters degree in civil engineering and I never knew this stuff. Awesome stuff, glad I subscribed :)
Yeah I was speaking to my civil engineering friends a few days ago and they said the same thing. Yer all about that steel and concrete.
you never knew*
thanks DazeNure, corrected it, was a little drunk when I posted the comment :P
let's be real education sucks on this planet!
I think you misunderstand the purpose of higher education. It teaches us how to learn, how to evaluate, ask questions, experiment. What topic stays static? Very few. So you can't learn what you need for a lifetime within a small length of time. Only how to learn.
One of the most approachable, rapid descriptions of how copper alloying of aluminum works and what it allows. Y'all have a great series of videos, so I'm crawling them as I get some time. The dozen or two I've seen so far are well edited, quick-paced, clear, and use a balanced mixture of graphs, pictures, and such to convey things clearly.
Just imagine being that guy that had all his money in aluminum and be alive that day the price dropped. lol
Thats what i was thinking lol, poor investment XD
Like the ones that today invest in bitcoins and similar stuff
The price drop happened VERY slowly over 50 years.
@@MrLeCapitan way to ruin the joke.
Fun fact, last year aluminium was sold for $1500~ per ton, lowest point in over 3 years.
Today, it's sold for $2488~ and still increasing.
HUUUGE profits.
You left out the 5 lb cap on the Washington monument being aluminum, because at the time it was more precious than gold.
Hey everyone, hoped you like the video. If you want to ask me anything or just say hi, hit me up on twitter. I will be a lot more responsive there. My username is Fiosracht (which is the Irish word for curiousity)
So here's a funfact:
the first engine propelled flight was actually by a German engineer called Gustav Weißkopf. That just got confirmed a few years ago, as historians found the documentation of a witness, with wich they could confirm the date, which was only days before the Wright Brothers.
NOT true - You cannot provide one bit of evidence.
When you have the evidence come back but we will not hold our breath.
Seond your claim does not indicate that it was a manned flight.
The Wright Brother's flight was manned and it was photographed.
from German Wiki
In the ten years after this alleged flights over two or over seven miles
there is Gustav Weisskopf never again managed to reproduce these alleged
performance, although he has built numerous aircraft and even made
numerous unsuccessful attempts to start.
jajajajajajajajaja you are a fool
+crosstimbers2
Historian John Brown researched the history around the Wright Brothers and Weißkopf for a long time.
In the Townlibrary of Pitsburgh he found Newspaperarticles from 1901, which describe detailed Weißkopfs first succesfull flight on board of his Plane 'Nr. 21' in Connecticut onAugust 14th 1901. There are articles by 'Bridgeport Sunday Herald' and several other Newspapers (274 Newspaperarticles in total), which are enough proove to state his manned flight as a fact.
I would strongly recomend the book 'Gustav Weißkopf und die Brüder Wright: Wer flog zuerst?' (ISBN: 1533605688) if you speek German good enough.

PS: he was an American citican at that point, he had imigrated to the US, so you can calm your patriotism, America still was first, dont worry. There is no reason to call me 'a fool' or rage about this topic, we are all smart adults (I hope).
+crosstimbers2 the first flight manned confirmed and proved was by Santos Dumont, Wright Brothers did use a launching rail, and Dumont won the Aero Club competition in France 1906. You can invent anything first than anybody but if you don't come to prove your achievements you are a fool.
Junker is pronounced like Yunker rather than how you pronounced it.
This guys voice is so nice to listen to
Agreed. It's nice to hear a fairly strong Irish accent that's actually easy for non-irish to understand.
+Falcrist irish? i thought it was german
Adam Malik DEFINITELY Irish. There's no mistaking that lilt.
+Falcrist is it? usually irish is inaudible to me
Adam Malik Please refer to my first comment! :D
BTW, Junkers is pronounced yoon-kers
Ja! Das ist because es ist German!
Ja! Ach Ja!
Es ist Deutch
Also, it’s pronounced “a-LOO-min-um”
lol... ya... same as that idiot that think he's god's gift to the EU... well... actually the EU guy is related to the airplane guy.
watching this as an aerospace engineering student was super satisfying; glad to know there's more people out there interested in our craft :)
Very nice video! I just spent the last year in engineering college learning much of this and you simplified and summarized it beautifully. I think it even helped strengthen my understanding. Thanks a tonne!
Yeah I always found metallurgy a bit over complicated in college, we don't need to think in 3D or understand the physics to the atomic scale. Just knowing the basic mechanism and understanding the phase diagrams is the most important part.
I agree, even though i find metallurgy fascinating i hated studying it, mostly because our professor expected us to memorize everything including the graphs.
I can still draw the Fe3C diagram just from memory.
Another amazing video! I'll definitely be supporting you on Patreon from now on. And I was already a huge fan of the vlogbrothers and all the awesomeness Hank and John inspire/support, but to find out that they're sponsoring a small, yet very informative channel like yours is just one more reason to love them.
A small note at ~3:35, I'm pretty sure that the entire plane will not move at the same time like you show. Breaking all those bonds would require a lot of energy. The copper in duraluminium is more used as a barrier for the progression of dislocations which are always present in material and are the source of plastic deformation.
Aside from the excellent content in your videos, you have a very impressive and humble style of presentation. Like you, I've been following many UA-camrs for years. There's a lot of great content out there, but for science-oriented channels like this, I really appreciate the simplistic approach you take to presenting such sophisticated content. Nothing flashy, nothing over-the-top. You have a way of making the content speak for itself. Glad to see your channel is still growing and I wish you continued success.
3:19 Companion Cube?
Same thing I was thinking.
Look it up. It's from the game "Portal"
lmgtfy.com/?q=companion+cube
An object in Portal I believe
Not an object. A dear friend.
This is cool! I've been learning about stress-strain of materials, age hardening, and atomic structures. More interesting than the textbook for sure!
I started high school this year already thinking about engineering as my future job, and your videos just confirms how beautiful this subject is. Continue with this great job, I simply adore it.
Boy! You guys make complicated stuff clear! Even for me! I love the pace and graphics of your videos! Thank you!
love the blue print background
These videos are so good!! Amazing job!
Thanks! Do you have any more videos in the works? I really enjoyed your Nerf gun one
Thanks! Yup! We've been a super busy with our day jobs but we'll have something out within the next week :)
I just discovered your channel. I am currently studying civil engineering and find your videos really interesting. I have watched a lot of them in the last few days. All the animations are very well made. The way you explain things in makes it very easy to understand, even some of the more complex topics.
This has definitely become one of my favorite channels. Great job! :)
as a fan of the vlogbrothers and their numerous channels, im both happy, and not surprised to see that they sponsored your content. Keep up the fantastic work and I'll continue to watch and support everything you create
Titanium and carbon fiber composites: allow us to introduce ourselves.

*see's price tag of titanium & carbon fiber*
Aluminum it is..
@@Skip.8221 no he is talking about the SR-71 Blackbird the fastest plane in the world it needs Titanium because of the high heat created at high speeds and Titanium can resist high tem the best at the time it was designed.
@@mi4johns loll😂
You meant to say cannot be "overstated". If it "cannot be understated" it would mean it was insignificant.
Very good video. Keep up the good work, friend.
Charles Edward Taylor was an American inventor, mechanic and machinist. He built the first aircraft engine used by the Wright brothers in the Wright Flyer. As an aviation maintenance student i feel compelled to give credit to Charles for actually making the engine and not the wright brothers
These are very informative and helpful. Thanks for putting in the time to make quality videos. A lot of people don't understand the effort it takes to make good videos like you do.
Just contributed subtitles for Russian, hoping to see them live any time soon... Cheers!
hellorobots thank you! I'll have a look, haven't got a notification for it yet for some reason
OK, thanks a lot!
hellorobots I don't even speak Russian but thank you for doing that.
TheCompulsiveWinner thank you for saying this
Same here. Thanks for contributing. We need more people like you!
This is just an awesome channel. Keep up the good work.
thanks Dustin. New video out tomorrow!
Your videos are fun to watch, and easy to learn from. Never thought I'd say that about an engineering video, but you proved me wrong. Keep up the excellent work!
Thanks so much for the video Brian, I'm studying the very same principles you mentioned at the moment and it's very inspiring to see how such principles can change the world! Thanks so much keep it up!
For a material scientist student like me, this review was absolutly amazing.
the tip of the Washington Monument in Washington DC is a pyramid of Aluminum, which at the time was worth more than gold
This video was so much more interesting than what I expected that it would be. Amazing work!
You've got a winning formula here. I could watch your channel all day. Very well put together. You deserve 10 times the subscribers!
I'm glad that Hank and co are behind you, he's good people.
Who the eff is Hank?
+Geph C Hank Green, from the vlogbrothers/scishow/crash course
Geph C As Erica said Hank and his brother John are Vlogbrothers (who apparently sponsored this video), though I know him better from Scishow. If you get a kick out of Real Engineering, there's a fair chance you'll also like a lot of the stuff Scishow does.
"Who the eff is Hank" is an inside joke from the community arround the vlogbrothers xD
And given that +Geph C's Profile pic is a "Hanklerfish" I'm certain that he/she just wanted reference that joke ^^
Hank is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing farther north than any other broadleaf tree. Young Hank trees have smooth, coppery brown bark, while older trees have white, papery bark, of which the outer layers can be stripped off without killing it.
I wish my physics class focused more on technology instead of endless calculations about abstract concepts. I'm so glad I graduated from high school.
I don't know about you, but I learnt about materials in chemistry.
We did polymers (High density, low density, thermosetting and thermosoftening)
Nano particles and properties of metals.
What you're looking for is engineering, which is based in physics.
Carlos Saraiva - Wrong. Technology can exist without a theory explaining it. If it works, it works. No theory necessary. Often...the physical explaination follows the technology. There are endless examples, but I'm sure you can think of several off the top of your head. There is one in this video.
brentmel any and all sciences work in the same frame: Theory -> Practice -> Theory. We first make a new assumption based on knowledge available, then test this new idea in so called 'physical world' and then refine our theory...
S C - I think you are confusing technology with science
This was an amazing video to watch as I just started Metallurgy this semester at MST. Keep up the good content.
This is exactly what I was looking for; UA-cam videos like this one that combine my engineering education with fun and simple real life examples. This is going to motivate me 👌🏼
I really like these videos!
Real Engineering: Great content and Real knowledge.
Comment Section: I love the bLuE BaCkGrOuNd.
I love your channel and I really like your personality. I am learning so many different things and the visualizations are incredible! Go on with your wonderful job!!
Great video.
I am an Automobile Engineering graduate myself. But many of concepts I didn't understand properly enough back then, were made easier to digest due to some of your videos. For example. Most of planes and aerodynamics videos. That's very great effort from your side. Keep up the good work.👌😇👍👍
Duralumin!! Has anyone here read Mistborn?
yes, i was completly surprised as well.
As a non-native speaker I didn't recognise it, but it's great to see fellow Sanderson fans here
It's my favourite book series so far. Sanderson is a master at writing.
yes literally loved those books so fuckin much
you should read the way of kings its also a really good book
more on materials please?
This info wasn't even found in my university Material Science class. Thank you for sharing with us common folk!
You got sponsored by Hank and John?!?!? Congratulations man!! You are on your WAY.
Great vid. And I'd love something similar on composites. They are one of my very favorite topics. I've been working with them for about 10 years now, and I'm always looking for new projects that warrant them.
Oh, vlogbrothers are supporting this? Cool :)
If you call gold a precious metal, imagine a world where iron never existed
We'd probably never even discover electricity and be able to use it to refine our aluminium.
It was called the “Bronze Age”.
@@lawrencedoliveiro9104 XDDD
Thank you so much for all of these amazing videos
Just found your channel and absolutely love it! Great stuff, keep up the good work.
Not "junkers". It's pronounced "yunkers". It's German.
+Andy Wilderness Wouldn't it make sense to be pedantic given the nature of engineering? Therefore one should be precise in their pronunciation.
Andy Wilderness no it's not, you don't need to be a rocket scientist to know how to pronounce juncker
So why don’t you write the name of the country correctly as “Deutschland”?
And it’s “you’n’kers”.
@@james-ch I mean if you don't know where the name came from it's difficult to know how to pronounce it.
0:50 You mean Napoleon III, which is not "the" Napoleon.
I've say 20 subscriptions, but nobody seems to get the admiration by their subscribers as much as you do, keep it going your videos are so interesting! :)
Good for you man. I enjoy seeing growth in sponsorships.
Just one small problem, the material that changed the world is... plastic.
They are both incredibly important, but aluminum is used for bigger things, like buildings, and aircraft, while plastic is more used for things that need to be light but not strong, such as small household items, or children's toys.
Plastic is also used to make many boats and some houses and roadways.
Julia Plastic has definitely made it's contribution, but there is no doubt that Aluminum has made a far greater impact on the world of larger goods than plastic.
i know
@@skepticmoderate5790 Not entirely true.
Plastic is often used in aircraft construction, especially on modern skin sheets. When someone says anything about carbon fiber or kevlar or composite on an aircraft, they usually mean a honeycomb structure with six sheets of fabric held together and protected by thick coatings of epoxy resin.
YES, YOU SPELT ALUMINIUM CORRECT
No he didn't.
love your videos, very nicely put together, entertaining and highly entertaning. keep up the good work!
really enjoyed this, reminded me of some of my favorite university classes
Wow! I've heard of aluminum, but this "aluminium" sounds amazing!
Both words are right.
only americans pronounce it "aluminum", the rest of the world says "aluminium" and the narrator is Irish
Nicolas Dolgin Wow, thanks! If you don't mind, and have a few free moments...I mean, if it isn't too much trouble, could you answer a question for me?
How do Irish people pronounce "irony"?
'only americans pronounce it "aluminum", the rest of the world says "aluminium"'
That should be easy to prove.
Did the narrator really pronounce "Junkers" as 'junkers' ???
Seriously?
when carbon nano tube will replace most of metal?
The main problem is that it is hard to mass produce it
When plate from carbon nanotube won't be more expensive than gold
When its actually viable....
One small carbon nano tube is strong, but the problem lies in using it in a macroscopic scale. You can find interesting articles about carbon nano tubes not being the future material as they used to think :)
Still a really interesting invention to use together with other materials though, but not in itself.
In conclusion, not in the near feature :(
Well researched and produced video. Enjoyed it and learnt something at the same time!
some great educational videos you are making there! not only intresting history but also nice technoligy details i have not known before! please keep it up :)
great video but i think junkers is pronounced yunkers
Ironically, the British scientist (Humphry Davy) who named the stuff called it 'Aluminum'. Then _another_ British scientist (Thomas Young) took the liberty of renaming it 'Aluminium'.
That caught on, and even more ironically, the _Americans_ called it 'Aluminium' while the British occasionally insisted on calling it 'Aluminum'.
In 1828 American lexicographer Noah Webster reverted to 'Aluminum' in his dictionary, which caught on in the non-scientific portion of America, while scientists worldwide continue to use 'Aluminium'.
I learned this yesterday from Bill Bryson's Short History of Nearly Everything.
Apparently the British establishment didn't like the fact that the name deviated from the popular 'ium' naming convention of the time (sodium, potassium, cadmium etc).
So while British people like to claim Americans simplified the word (I'm British btw), I now know that it is us who are not using the correct original name!
Best description of age-hardening I have ever seen. Great video!
Great work! Your videos are awesome :) I watched all of them. Keep making them please
Hey +Real Engineering What are your thoughts on Elon Musk and his vision to shape the future in a better way? Also, what is your name if I may ask?
Elon is a huge inspiration to me. He is going to be remembered for a very long time. My name is Brian :)

always get excited when i see the now iconic blueprint and white text on my homepage.
Thank you for pronouncing aluminium correctly as some say aluminum
Both terms are correct.
Technically, they're both correct.
+Stu Beet lol u got triggered really easily
Aluminum is the correct accepted pronunciation in the US. Please refer to the Aluminum Standards Handbook if you cannot bring yourself to accept that as fact. There are 320 million Americans that pronounce aluminum that way.
You can check out the Aluminum Association here.

I think I should have uninstalled PUBG atleast 2 months before!
I dont want want to repeat nor I want bad grades😢 but its too late!
This was such an epic video. Just put the first year Materials in Mech Eng into context. So cool! Thanks so much!!
This video was really detailed and simple. Great video!
Aluminium might miss it's moment. Right now Aluminium is getting cheap enough to replace steel. However, with 3D printer Meta-Materials being able to create designer atomic structures we might not even use metal anymore, but synthetic carbon based materials such as nano tubes and improved forms of graphene.
What? Meta-materials are just used to selectively block certain portions of the electromagnetic spectrum or sound waves. And they are not actually a new material. They are just nano-scale structures built out of other materials. They could easily be made of aluminum itself. They also offer no improvement in strength-to-weight ratio. Why would they replace aluminum?
finally , someone that says aluminium right :')
Lol,I'm American,and I say aluminium.
w wyborn i wonder if Americans use uranium of uranum for their power plants... hmmm
