This is, indeed, a reupload - there was an error in the graphic at 2:00 that we tried to address with a pinned comment, but it was a little too much to clarify that way, so the graphic has been fixed!

@mcdrums87 6 лет назад

...and it’s back! For those looking at careers, chemistry vs. chemical engineering (IMO) is the best example of how a science degree differs from an engineering one. Chemists can tell you everything about a chemical, while chemical engineers will figure out how to produce a chemical in usable quantities. This is especially true for pharmaceutical companies employing chemists to develop the right drug formulas and chemical engineers to handle production. Obviously, both are related-you can’t really do engineering without the science-but as far as careers are concerned, a “science” degree will prepare you for more research, development, and lab work. An engineering degree will give you the design and production background for products and manufacturing.

@alexv5581 5 лет назад

Your point is? Without scientists engineering is nothing. This is coming from an engineer. What makes you think a scientists isn't capable if doing engineering work? Obviously any person with a degree in science has the brainpower, so that is not an issue. I have met many engineering students that struggle with the science aspect of things. Everyone thinks differently and no need to bash or have the discussion which degree is "better".

@jordanandrews6479 4 года назад

It also depends on how you apply your degree. I have a chemistry degree, but my job is a large scale production chemist, which is quasi-engineering. Either way, it's all pretty cool stuff!

@joeybroda9167 6 лет назад

I'm glad my field got mentioned. As a ChemE you can have a wonderful career making methane gas from landfills, manure pits, and sewage! This isn't sarcasm, I actually love my job.

@joeybroda9167 6 лет назад

In my degree, I took six dedicate math classes (linear algebra, calc I + II, multivariable calculus, ordinary differential equations, an ad calc). Most o the my engineering classes also used lots of math, especially integrals, derivatives, and differential equations,.

@gslim7337 6 лет назад

I actually design BioFilters for removing odour from Sewerage Treatment Plants and yes I do enjoy my job. I would have liked CrashCourse to mention the fundamentals such as Process Flow Diagrams, Mass & Energy Balance and Piping and Instrumentation Diagrams.

@jlhillmann79 6 лет назад

Surprised you didn't mention Mass and Energy Balances. In my experience, that's one of the key fundamentals that differentiates ChE from other engineering disciplines. I work with all different types of engineers (they have strengths/knowledge/experience that I don't), and it's always interesting to see how ChE's always seem to approach a problem thinking about black boxes with inputs/outputs, while other engineers don't.

@austinjackson761 4 года назад

Chemical engineer intern at an explosives plant! I love what I do. For me it’s perfect, I get to be creative with my projects, do calculations to solve problems, go out in the plant to get out of the office, work in teams and collaborate to achieve a common goal, and I get to see the work I do save the company money by making things more efficient. It’s challenging but very rewarding when you complete a project and realize you made that improvement. Be aware, not every company is fun to work for though. Make sure the people you work with are happy, motivated, and collaborative.

@pankajkhushalani 5 лет назад

English is not my first language and I usually use captions but the narrator in this video had such brilliant diction that I didn't need them. Apart from that, this video gave me a good insight on Chemical Engineering. I am a Junior Science College in India where we study Physics, Chemistry, Math/Biology, a language and a vocational subject such as Electrical Maintenance or Computer Science or Psychology or IT. In about 2 months, I have to decide which branch of engineering I should choose. This video helped a lot.

@saidzaid-alkailani519 6 лет назад

How is the Haber-Bosch process not mentioned? It is literally the most important chemical engineering process and the first thing most chemical engineering professors mention.

@Billionaire_B 6 лет назад

food science is a branch off chemical engineering and is making a new revolutionary development not only within the food themselves but also looks at new packaging materials and ways to extend shelf. just got to love chemical engineering

@SkywalkerAni 6 лет назад

Chemical engineering is a primary reason I have a job- I work in an office dealing with hazardous waste, and someone has to make and mix all those chemicals! For the record, I am not a Chemical engineer, the chemical engineering processes is a huge reason I have the job I do.

I think there is a mistake in 4:30 it is not polymerization it is actually Alkylation Polymerization is when we repeat the same molecule a certain quantity

@gelgamath_9903 6 лет назад

I kind of feel like this whole engineering series is glossing over or not even mentioning some of the darker sides of engineering. For example we just did an episode on chemical engineering without mentioning Fritz Haber

@joeybroda9167 6 лет назад

I was kind of surprised by this. This episode focused more on the idea of unit operations, so from that perspective I could see why Haber wasn't included. But Haber is definitely the most famous chemical engineer and an absolutely horrid human being.

@Bird_Dog00 6 лет назад

Fritz Haber is an interesting case. On one side, he played an important role in chemical warfare in WW1, but on the other, he was also instrumental in developing the Haber-Bosch process. And without that, there is a good chance we wouldn't be here to talk about it today...

@bryanhumphreys940 6 лет назад

He was, indirectly, responsible for the deaths of thousands and the births of millions. Yeah it's a moral quandary for sure.

@joeybroda9167 6 лет назад

i don't think we should understand Haber as a sum of how many he helped and how many he killed. We should look at this and say that science has an awesome potential. That the tools of modern science can uplift our world, or they can end them. And that's a really scary prospect. That's why we need to keep nationalists like Haber away from decision making. He was fine with letting tens of thousands of people choke to death on mustard gas. He was a horrible person and no amount of fertilizer will save his memory. This is not a moot question now. So much of science is advanced with money from defense departments. That has an effect on science. It increases our ability to build more fantastical machines of death. That is to no one's benefit, really. But if our back is against the wall, people will innovate and design. It will drive science forward that can have both good and bad repercussions. But if we are scared, we will try the bad stuff.

@science-health-safetymusic2322 5 лет назад

The most difficult Engineering course because chemical engineering goes beyond untouched and the unseen, nuclear chemistry we always imagine all the time cos we can not visually see them unlike other engineering courses not studying proton, neutron, positron, nuclear radiation etc.....they actually see and touch on hand when they practice their professions...but we Chemical Engineers we can not see how gases behave how chemical reactions actually happen etc.

@kierannurmi5488 6 лет назад

Despite the commonality of units between industries, most sectors (in Australia at least) will still demand experience in their particular sector which tends to work against chemical engineering graduates.

@munbun75 6 лет назад

I really hope you do one in this series on biomedical engineering. My soulmate (best friend not so) studies that and I would love to be able to show her an episode on that! I love crash course and all the information you bring to my life! ^_^

@mikkelfondt5425 6 лет назад

Great video, but you skipped one of the most important parts of the history of Chemical Engineering, Justus Liebig and the colour (yes, colour, not color) industry. Liebig changes chemistry from being a supporting subject for medical student to making chemistry one of the most important subjects because of the booming synthetic colour industry that singlehandedly made Germany a financial powerhouse, dominating Britain and competing toe to toe with USA.

@mikkelfondt5425 6 лет назад

Also, on a side note. The waste products of the Leblanc-process didn't just make putrid-smelling waste; the hydrogen-chloride began making fumes from the waste pile of calcium-sulphate, causing major hazard damage to the nearby residents.

@birdgod5584 5 лет назад

That sounds interesting, but most crash course videos are very short. Maybe they can make another video about ChemE where they can go into detail about the colour

@rkpetry 6 лет назад

*_...it'd also be nice to categorize this as 'electrochemical' engineering 0~20 eV 0~200 K°K based on atomic electron quantum orbital structures and 'chemical' mechanics-i.e. not, atomic nuclear, chemistry, 0~20 MeV 0~200 G°K, nor subatomic particles 0~20 TeV..._*

@beee7892 5 лет назад

Why did i only now see this... I was looking for what to take for college months ago. Well i still took chemical engineering anyway

@ManfredDudesonVonGuy 5 лет назад

First, as a chemist who started in a Chem E degree, Chem E has much less to do with chemistry than you portrayed. The job of a Chem E is to take what chemists figure out in beakers and make (literal) tons of it for industry. The real chemistry is already done well before a chem E does anything; they're really just systems engineers that focus on chemical manufacturing. Second, the chemical you put up as petrol/gasoline is not that chemical. That is the alkane nonane C0H20. Gasoline/petrol is a mix of many hydrocarbons, but is defined by the presence of octane C8H18 relative to other compounds. Also, C7H14 is heptane, not heptene.

@chimaijemotitolouis8291 6 лет назад

Ziggy Stardust isn’t that a subfields of chemical engineering?

@nealdesai8779 6 лет назад

Chima Louis there is certainly a large overlap, however chemical engineering is more about the process to create chemicals, rather than creating new ones. So a chemical engineer would be working at a factory, while a Materials scientist works in a lab.

@Lioralon1 6 лет назад

it's a very broad filed, so some materials engineers do things similar/overlapping with chemical eng, some work is closer to mechanical eng. (materials eng. has branched out of mechanical eng. actually!). really depends on the direction you go. Generally the main difference to chemical eng. is that while they work the process we work on the materials themselves, and also they work mostly on fluids and gases while we work mostly with solid state or something in between solid and fluid.

@Bird_Dog00 6 лет назад

I was actualy a bit surprised they didn't mention the Haber-Bosch process, given that it was as crucial to increasing the earth's carrying capacity as inventions such as irrigation or crop rotation.

@magzieforfunj187 6 лет назад

Articles about the history of chemical tend not to mention specific processes. They mention George E Davis as father of Chemical Engineering, introduction of Unit Operations, Chemical Engineering becoming more mathematical with the introduction of transport phenomena and reaction engineering. They probably didn't mention those process because of a combination of their sources don't mention them and trying separate the chemistry from the engineering.

While the video shows engineering reality as a life like Big Hero 6, groups of people knowledged in different aspects of engineering working together. Anyone know the video / creator? Let me know and thank you so much.

Is chemical engineering ≒ material engineering ? Every technology have to be materialized into material resources , like tools , machines , fuels or facilities , to be utilized. Then , fertilizer , plastic , semiconductor , new medicine …… chemical engineering is vital to all the stages of civilizational development 💖.

@elia-eo3bf 4 года назад

The difference between them is the main subject of chemical engineering is about processing techniques and the material engineering about the properties of materials
