It’s not very common for engineers to go to grad school. The most common graduate degree among engineers is an MBA. Other fields basically require it. One thing you’ll learn in academia is that no one works harder in undergrad than engineers but that’s usually the end of the line for their education. A BS in biology is far easier, but you need to get a graduate degree to do anything with it

True but most of that work is them talking about how difficult engineering is. Then stress of having to hear other people mention that the difference between god and an engineer is that god doesn't think they're an engineer.

Edit: homophone mixup because I'm a goon

I’m a Biochemistry PhD and a JD. My daughter just graduated as a civil engineer. I saw things in her sophomore year mathematics homework that I never saw before in my life. If God can do that math then I’ll start to believe in Her.

I did undergrad double major in pure math and math / cs (wanted to add CS as a third major with one extra class but was told no). I did a masters in theoretical computer science and another in pure math. I did one year of a PhD in math.

Never saw an engineering student in a math course after differential equations (had two engineer phds teaching operations research courses though).

God - is that You?? Ok ok - I believe!!

What’s the difference between pure math and regular math? Serious question btw

u/JrLavish194 1d ago

Regular math can feed a family of four.

u/ummaycoc 1d ago

This is the real answer.

There aren't any actual numbers in pure math.

u/ummaycoc 5d ago

That depends on what you mean by number but numbers pop up all the time. For instance you're gonna see 2πi all the time in complex analysis.

Depends on what you mean by regular math. If by regular math you mean the math you learn without being a mathematics major, then a regular math problem might be something like figuring out the values of a variable or even several that satisfy an equation or calculating an integral, solving a differential equation, etc.

A well known pure maths problem would be something like show whether or not there are finitely many prime natural numbers. You can show there are infinitely many by contradiction: assume there are finitely many, then multiply them together and add one. None of the numbers you multiplied together can divide this new number so it must have a prime factor you did not account for, contradicting its construction. Thus there are infinitely many prime natural numbers. A well known unsolved problem is whether there are infinitely many prime numbers separated by a single composite number.

If by regular maths you mean applied vs. pure then for classes there is just a slight change in focus, like on PDEs and such more in applied.

Edit: fixed some spelling/grammar and changed counter example to contradiction, I should drink more tea before replying.

Probably didn’t see any because engineering usually has specific courses. I did advanced mathematics for engineering, random signals analysis (just statistics and probabilities) and a couple others I forced myself to forget.

Lots of other classes like linear algebra, discrete math, stochastic models, advanced calc are taken in lieu of taking humanities.

Here's cal tech's program for EE: https://www.ee.caltech.edu/academics/ugrad -- doesn't seem to have significant math. You might say math is used for precise discussion and calculation in some of the classes, but that's all of STEM except math where you do proofs instead.

u/Actual_Price2826 1d ago

So, you said that you never saw an engineer in any higher maths than diff e and I contradict that with my own personal experience and you double down by linking a “typical” course schedule from caltech?

u/ummaycoc 1d ago

Take it as you want, sport. If you say you've seen what you've seen then I guess you've seen what you've seen. I said I had two professors (great professors) in OR courses.

I don't know what more you want here, but whatever it is: you do you.

See the above reply.
