Some people say there is no difference between a scientist and an engineer, while other people think the two careers are totally separate from each other. Scientists and engineers typically have strong opinions about what they do, which makes sense, since it involves discovering, inventing, and improving pretty much everything, right? How would you describe the difference between a scientist and an engineer?

The Difference

Scientists are the ones who create the theories, engineers are the ones who implement them. They compliment each other, and often work together, the scientists telling the engineers what to make and the engineers telling the scientists the constraints that said thing to be made doesn't meet. They are indeed different, but they work very close together.

— The Walker

Not VS, but AND

Scientists ask what happens and why in the natural world, while engineers use the answers scientists find to create new inventions and ideas not in the natural world. Both are equally important, as without scientists engineers would not create, and without engineers the research scientists do would be wasted. They go hand in hand.

— ashley

It is not VS but AND

There is hardly any difference between the two. In the end it is all mathematics and physics.

— Logical

Science vs Engineering

Science is about knowledge and engineering about invention.

— Aburo Leusttas

Computer Scientist & Software Engineer

Science is a lot of high level theory and engineering is implementation and optimization. Often a Computer Scientist will come up with a plan that a Soft Engineer have to modify because the theory is not realistic enough to be in production. Engineers deal with math, efficiency and optimization while Scientist deal with "what is possible".

A Scientist would be happy spending a million dollar creating a trinket worth 10 dollars as long as it's good science. An engineer don't have that luxury.

— Ying

Can you tell I do English Lit?

Engineering is, in a way, more of a science than science itself is. There is something integrally artistic about searching for knowledge simply for knowledge's sake, as a scientist does, and something slightly less so about the functional, practical, minimalist themes behind most engineering. Science is more romantic, in a way, a never-ending search, engineering limited to goals, profit margins and physical means.

— Michael

Scientist View

I am a scientist who works daily with engineers. I'm generally treated as one of them and often perform the same duties. The main difference is that a scientist focuses on the unknown while the engineer focuses on the "known". We actually complement well when the engineers can overcome their ego.

— Nate

they are the same

i think there is no difference between a scientist and an engineer because both work for nature and humanity

— aqeel

Scientist vs Engineer

As we can see from the list of the Noble Prize in Physics, we can already tell who inhabits that area. Scientists are the ones who starts the process, and their work are sometimes theoretical in manner, but really exciting both mathematically and mystically.

Engineers doesn't really need to go that far to serve their purpose. I seldomly see an engineer who knows the strong force.

— muon

THE Difference

Engineers trained for Using tools, where Scientists are trained for Making them. Engineers are Hard Workers, Where Scientists are free Workers. Engineers Spend most of there time to looking at a solution where Scientist spend their time looking at the Problem. Engineers always treats the decease where scientist treats the root of the deceased. Engineers are narrow minded and scientist are broad minded.

— Supun

They are cousins!

Scientists develop theories and work to verify them, Engineers search in these theories to "optimize" things in real life. For instance, scientist may research and find out some properties of a material, engineers look for how to utilize these properties in optimal manner while considering efficiency, cost, and other aspects of interests.

There is an overlap between science and engineering. In fact, you may find an Engineer who "develop theories" and a Scientists who "optimize".

— Motasem

Science Vs. Engineering

Scientists, Engineers (and yes, managers) are all after the same thing! Science explores the phenomena of nature and attempts to find the laws that govern them; Engeering attempts to use the laws of nature (already known) to replicate them in situations leading to usable end results; Management provides the logical frame work (What and why -- the strategy and when and how [- the operations) for our efforts through science and engineering! Hence every professional is a scientist, engineer and manager (with different proportions, depending on their job assignment or career choice). Then what is technology? --- Technology is an integrated outcome of sceince, engineering and management pertaining to the phenomena of choice. This Nuclear Technology is the intergation of S/E/M pertaining to nuclear fission or fusion. Automotive technology is a collection of S/E/M efforts pertaining to automobiles and hence include I.C. Engine technology, Steering and Control technology, etc.

— Dr. K. Subramanian

The Honest Truth

Scientists get PhDs; Engineers get jobs..

— TheWanderer

Everyone else writing cliches

Engineers and scientists do the same jobs. Engineers only learn a particular field in great depth. For example, a physicist will know maxwells laws, and basic circuit theory; but an electrical engineer will have studied next to nothing but electrical phenomena for the same time. Engineering also crosses the traditional boundaries of science- chemical engineers study the physics of chemical reactions on large scales. Both jobs are problem solving jobs. Both involve design testing and innovation. Both can be research jobs involving the study of new phenomena

— Studied both- worked as both

Engineer

"All engineer are scientist, but all scientist are not engineer"

— Narendra thapathali

they have a difference

though my knowledge to both engineering and science is limited but according to my level I could say that science allows us to have more information about how the universe that we live in does work ,but the engineering uses scientific principles to convert universe resources into some thing useful so engineers always feed rules and laws provided by scientists to make the life easier and comfortable .

— sharmarke

scientist

A scientist invents a law and an engineer applies it. As long as science is concerned both use it and misuse it .

— hari

Engineer vs Scientist

Scientists discover the nature such as pressure directly prop to temperature, they think hard to find the laws of nature. On another hand Engineers uses these laws of nature to invent to equipments such refrigerator, engine. And also engineers uses scientists laws to triumph in their inventions. Engineers are concerned with costs and scientists are not.

— future engineer

Engineer vs scientist

Scientist discover new things...they work in laboratories to research and discover new cure to disease ultimately for the living community...engineers makes things happen...engineers create things...ultimately for the benefit of society as well....both have their own area of expertise....

— McQueen

Engineer vs Scientist

engineer is a person who implement new things like devices or objects. he produced new things which are artificial not natural. but a scientist research on the natural things .discover new things as well as livings things like animals etc.

— usman ali

scientist

scientist suffer when working but engineers just copy scientists

— uranus

Scientist vs Engineer

Scientist for invention of new theories. Engineers for applying those theories for piratical applications.

— Narendra, Scientist

Engineer vs. Scientist

Engineers solve practical problems,Scientist solve theoretical problems.

The Library of Science

The library of Science is already written in nature. Order, math, physics. Engineers protect and apply the library and learn some unwritten parts along the way. Society Profits. Scientists learn and discover the unwritten parts and are paid for their efforts. Engineers ultimately accept or reject theories to the library. Scientists and Engineers are idealists and dreamers vs pragmatics and doers. Both use the same library, and the fools in both houses believe in magic and chaos, and teach the wide-eyed children to believe too. The rest of us then spend lifetimes trying to undo the brainwashing thru science or practical example. The question science can't answer is who wrote the library of math, physics, and laws of nature, and forced all of nature to follow all of the laws of science all of the time. Unfortunately atheist scientists try to discover/intuit the answer in a lab, then teach the little children their findings to the detriment of us all.

— RWJ PE

engineer vs scientist

The difference lies in that in Engineering we use science to make decisions for a product, project for efficiency, performance, better performance, low cost..etc, while the Scientist is about discovering, experimenting-provide the "building blocks" for the engineer to use and create and design.

— Rina

Easy

Scientists discover what already is. Engineers create that which isn't.

— Engineer

engineer vs scientist

Scientist they research n discover to the planet at large(nature) ...but few scientists apply that whereas engineer: research,discover ,apply and produce t

— touch

It greatly depends.

The difference depends greatly on the particular field of study. There are as many engineers involved in research and development as there are scientists involved in application and optimization.In my opinion the main difference is the old Artistic/cerebral dichotomy. Scientists usually go for more philosophical subjects. Whereas Engineers usually go for more mathematical subjects.

— Bio-med Eng

difference b/w eng. and scientist

i think there is a lot of difference b/w them . scientist discover something and thinks something different or unique while engineer do what other do.

— Nagesh sharma

It's bloody obvious

A natural scientist tries to understand nature, and an engineer tries to create what nature doesn't have by making use of what scientists have discovered.

— ChemEng

engineer vs scientist

An engineer works with the things which is already designed by a scientist . an engineer has some boundaries but a scientist need not care for any thing and he works on what a scientist should work .

— udhithsanthosh

scientist VS engineer

scientists will think deeply through the atoms but engineers will think beyond the atoms

— sathish chandhra

here is the diff

engineer is integral part of scientist,as scientist's work is a basic raw materials for engineer

— kamar

Engineer vs. Scientist

The main difference lies in the main field of work. An engineer is more on the physical aspect of matter (or materials) while a scientist is more on the functionality & "concepts" related to the matter (or material). However, both works on same scientific concepts of matter or material in the field of Science and Technology.

— MTMaturan

An Answer

I believe that there is a big difference between scientists and engineers. For one thing engineers are usually confined to building and designing. Scientists do not have as many boundaries and can really do whatever they want. However this could also include building and design. So as you can see there is some overlap. But scientists are more likely to do many more things including making theories.

— Scientist

engineer VS scientist

they are almost the same if we would look in general point of views, but i believed that scientist are those who always search for new things and tried to understand, but engineers tried to applied this science, by optimizing it, exploring the possibility of producing in big scale, but all this, will sum up in one "using science in service to mankind"

— lawrence

no such difference!!!!

I THINK BOTH ARE SAME ONLY DIFFERENCE IN THEM IS THEIR 'STYLE OF WORK'

— Susobhan

scientist is scientist and engineer

scientist is scientist and engineer but engineer is not scientist.

— vahid saadattalab

money vs glory

engineers work for money while scientists work for glory (scientists are compensated poorly)

— L

biggest difference

scientists always tries to modify and discover the things which are present in the real world. but engineers always things to do something new, like providing new facilities for peoples, create new functions or software to make the daily life easier and more easier.

— anurag rathore

answer

the difference between it is engineers are the person who protect those things which are made by scientist. scientist are making the things and engineering are giving the way to make that thing.

— Love Kumar

Simplest answer

Scientists discover things. Engineers build things.

— Jon

ENGFTMFW

Different mind set altogether. Engineer learns what is needed to get the job done and does it. Scientists learn for the sake of learning - they accumulate vast amounts of knowledge according to their whims, maybe discover something, write a book, and die. Dreaming vs Doing. BTW: if you think scientists are the only ppl making discoveries, look at which camp files the most patents.

— Dr. Ph.D Prof. LoL

Science

A phd, who also has a degree in engineering, is not a scientist because he has an engineering degree. He is a scientist in spite of it. Engineer is an overused term for anyone with a technical background who you can get to sign any CYA document.

— Villanova

difference, don't really know?

after checking out this wild search, by today's technology an engr isn't a scientist, however, if you relate to the early 1900's how could you not consider them the same?

— only 1 of me

engineering is science

both make observations, create hypotheses, make a prediction on what those hypotheses will find, observations and tests are done, the results are verified, then they use that knowledge to either create something new or create a scientific law (both can be done either by a scientist or engineer)

— engstudent

Amalgamation

A scientist researches the world using the scientific method. An engineer innovates new products with the results. Engineers may test their products to perfect them, but do not use the scientific method to research new things. Observation at most.

— ajw

Nothing Much

An engg is a person who makes the situations ideal for the scientists 2 discover and invent new technology which is helpful 4 human life...

— phyco-engg.

Two sides of the same coin!

Depending on what engineering you are referring to there are varying degrees of overlap (e.g. EE has a ton of overlap), but more often than not it stems from what engineering really boils down to: applied science. I do agree with the idea that science tends to concern itself more with the natural world where as engineering concerns itself with the man-made world. Ask anyone who is isn't an engineer or scientists and they think they have very little in common; ask someone that is one of the aforementioned and they will say they are nearly indistinguishable. It is funny to hear arguments between the two camps, but at the end of the day, everyone agrees that they build upon each other and advance one another. And if you are one of the two, you shouldn't let it bother you if lay people can't get it right...What are you doing outside the lab anyway?

— EMfortheWin

MS in EE?

Why is my Electrical Engineering degree called a Masters of SCIENCE?

— Ratcoon

They answer different questions

Scientists answer the questions: 'What is it?' or 'Can we possibly...?' whereas engineers answer the questions 'How do we...?' and 'What is it for?' Note, the middle two questions are where they overlap. (Note, as a scientist working in an Engineering Department, the 'What's it for?' question is one that causes me a lot of irritation)

"mad scientist" vs "mad engineer"

A "mad scientist" (as seen on TV) is an engineer but a "mad engineer" is not a scientist.

— George

Scientist=Ph.D

I am sorry but this is real simple. You can't be a scientist with out the "philosophy" part. No Ph.D=no scientist. If you have one you understand me.

— Marc Andersen, Ph.D.

Engineer vs Scientist

Something important to note is that obtaining a training as a scientist does not necessarily make one "theoretical or purely research oriented", neither does a degree in engineering automatically qualify one to a "practical based /engineer" for that matter. If a physicist by training takes a career as an engineer in a power generation firm where he spends over 10 years work as a Power Engineer, then he may as well qualify to be an engineer (in the making). An "engineer" by training, may spent his lifetime doing scientific/theoretical research after the first degree and may never see the doors of a factory etc, He may not in this sense qualify to be called "practical" or to be termed an engineer.

—Wakhanu

Undergrad Science, Grad Engr

Scientists face minimal risk of being wrong en route to a plausible solution. In fact, it is expected that we should be wrong several times before finally being right. Engineers face high risk of being wrong even once because corporate or government money and deadlines are at stake. When scientists become engineers is when we have to make our research profitable and work under the extreme pressure of being right on a deadline. When engineers become scientists is when we are asked to deliver solutions that raise the bar set or challenged by the competitor’s engineers and scientists, which occurs on every new revision.

—Engineering_Scientist

Definition depends on which one you are

An engineer is someone who uses the scientific method to develop practical systems for scientists to use when trying to apply the scientific method in otherwise impractical ways.

—Texas7

engineer vs scientist

Much difference between two, scientist discover and deal with problems of discovered things while engineer apply that discovery in industrial process by solving the problems to optimise for application.

— ilyas

The difference, in a parable

A man and a woman are at opposite ends of a basketball court. Every 5 seconds, they walk HALF the remaining distance towards the half court line. A scientist says, "They will never meet"; an engineer says "Pretty soon, they'll be close enough for all practical purposes".

— patmat

both play good parts

Scientists make researches and come out with theories which the engineers use in their works.

— _ n.c. william

The Box...

The scientist spends most of his life thinking outside the box. The engineer defines his own box, and never strays outside.

Engineer vs Scientist

Both are students of science. One maps the way while the other shapes it so that it benefits the human race. Both are equally important.

Taxes

Scientists make tax money become discovered scientific truth, while engineers make scentific truth become taxable. In a nutshell, of course

— Tanner

Scientist vs. Engineer

A scientist is the one who explores the principles and the laws which are the outcomes of experiments made in the laboratories or so, whereas an engineer is the one who applies these laws or principles to the materials alonwith the economics to materialize the thought of the products. Further, we can say that the scientist is the developer of the concept and the engineer shapes this concept to product. An engineer is the applied scientist too.

— Gulshan Kumar Jawa

is there an impassable gap?

I don't think there is insurmountable gap between scientists and engineers. One can be a scientist and an engineer simultaneously. An engineer can make scientific discoveries and a scientist can as well build devices.

— Chard

somewhat the same

they r some what the same but a scientist is an expert in science, esp. one of the physical or natural sciences and a engineer is a person trained and skilled in the design, construction, and use of engines or machines, or in any of various branches of engineering so now do u see the diffrence

— reggie

Lab coats!

We ALL know - the scientists wear the white lab coats and the engineers were the funny hats when operating the trains!

—mark_stephen

Engineer vs Scientist

Engineers apply known principles and data to design and construct equipment and systems. Scientists perform experiments to develop and evaluate descriptions and laws accounting for behavior of the world around us. There is extensive overlap of the two endeavors and great fun in discovering new, previously unknown information and functions.

—maurysis

scientists research, engineers build

A scientist is someone who's paid for do research, to discover new things, to explore new frontiers. An engineer is someone who has studied the known facts and is applying them to make or build a product which is used or then sold, such as a building, a table design, a bridge etc. The scientist may study the bridges that have already been built to see where their structural weaknesses are, and to come up with new ways to build stronger or more stable structures in the future. The newer generation engineer would then study the newer ways of improved building, then apply those new facts and methods to the newer things he or she is involved in applying science to to make them better than they were before the new scientific discoveries.

— drdavid

Here's my shot at that answer

Scientist invent or discover it and engineers make it bigger and cheaper. I have degrees in Chemistry and Chemical Engineering and have worked as both and this has been the primary difference between my two careers.

— Karen

Not good enough? Here's my formal explanation of the difference between a scientist and engineer.
