Rate My Physics and Math Work: 17-Year-Old Asks for Feedback

[ekrim]

Is it bad that I'm a junior in engineering and don't know half the **** that he listed?

nah, especially if youre not EE

Although you should be aware of those topics and at least know the general idea of them

 

[Cyrus]

? I am an ME and I know most of those.

 

[ekrim]

? I am an ME and I know most of those.

discrete math, number theory, non-euclidean geometry, quantum mechanics, differential geometry? If you know those, great, but definitely not mechanical engineering staples.

optics, semiconductors, a lot of the programming, relativity, are things maybe we've been exposed to, but I wouldn't say we would know from schooling alone.

I expect any ME to know what I put in bold.

 

[ekrim]

I expect any ME to know what I put in bold.

Fair enough, does it count if I've forgotten most of the list?

 

[Cyrus]

Honestly though, most of the 'physics' stuff I expect an ME to be able to follow along in conversation, but not know all the exact details. I took this stuff in general physics, and I know every other engineer did as well. So they SHOULD know this stuff at a basic level at the very LEAST.

It should not sound like chinese to their ears.

 

[carstensentyl]

Seriously, yes it is. And its not a he, its a she.

I'm not too concerned. Most of the things he listed were physics-related. I don't imagine the theory of relativity applies too much to building bridges.

Certainly, I recognize many of the things listed, but have never worked with their calculations. I'm afraid I'm more of the practical variant of engineer.

Why so angry Cyrus? I apologize for not keeping track of the females on the forum.

 

[Cyrus]

You never worked with the calculations I put in bold?

Thats impossible to believe. Let me know what bridges I should avoid driving on in the near future.

I hope your bridge does not have any air flow over it, oscillations, or possibly resonance. I also hope you can do calculations on the Molecular Forces and Solid Materials that will make up the bridge.


Tisk tisk tisk.

Certainly, I recognize many of the things listed, but have never worked with their
calculations. I'm afraid I'm more of the practical variant of engineer.

They call those construction workers. Dont be one of those, be an engineer.

Why so angry Cyrus?

Because I hate this false notion that engineering is some BS hands on practical nonsense. Its hands on after you have done the hard theory. Its the 'practical variant of engineering' that builds stuff that kills people.

Sorry, but it annoys me to no end when students make comments about not knowing something as if it does not matter. Statements like this:

Is it bad that I'm a junior in engineering and don't know half the **** that he listed?

Shows me you don't care about knowledge.

Sorry I misled you to believe that. I care quite a bit about knowledge and will be one of the first to argue when I overhear someone saying that engineers are 'trained on the job'. Not so much about the theory of relativity, however. Oscillations, resonance. I've done some class-based work on those topics.
Again, I'm only a sophomore in my major, and have plenty of civil classes, and otherwise, to experience.
I certainly would not say that I "don't care", as that is not the case at all.
