DaveE reacted to gmax137's post in the thread Other Don’t have a high enough IQ for physics so I want to give up with
Like.
I think everything in your post (after the first sentence) is incorrect. Here's what I know: Online IQ tests are meaningless Those... -
As noted above the conventional method for the determination of statistical uncertainty for a function is $$\Delta f = \sqrt{...

DaveE reacted to BillTre's post in the thread I Potential biosignature found in Mars rock with
Informative.
Here is some related information: One of the main origin of life on earth scenarios involves the interaction of fluids from... -
DaveE reacted to Ranger Mike's post in the thread Thread No-Go plug gage allows 3 turns to enter. That's too many! with Informative.
As with all things Government is involved with, confusion. The Old ANSI standard was 1 1/2 turns. two turns Max. Then the newer standard...

DaveE replied to the thread 3-terminal device external modeling.I fail to see the value of hypothetical questions like this. Your "new type of electronic device" is completely undefined. Suppose it...

DaveE reacted to .Scott's post in the thread Question about the voltage between two charged capacitors with Like.
Are you also connecting A1 and B2 together? If it's not a full electrical circuit, the voltmeter will likely read zero. Also, this...
-
DaveE replied to the thread 3-terminal device external modeling.You can't really describe a network without seeing what's inside of it. For a passive LTI network you should be able, with source...
-
DaveE replied to the thread 3-terminal device external modeling.I think the only thing you can say for the most general case is that the terminal currents all sum to zero (KCL) and that there are two...
-
This is only correct if you view ##\Delta L## and ##\Delta B## as fixed numbers. In a setting where you have estimated errors, it is...
-
Agreed. When rounding off to the so-called appropriate number of sig figs what you are really saying is "Don't worry about the...

DaveE replied to the thread Errors and significant figures.When I was a practicing EE, none of this ever made sense to me. These problems rarely mention the probability distribution of the data...
-
DaveE reacted to FactChecker's post in the thread Finding the nth roots of a complex number with Like.
By the time one takes complex analysis, he should be comfortable leaving it as ##\sqrt 2##. Leave the approximation accuracy for the...

Why not heat a stainless steel water container, that is fixed-in-place? If heated from below, the water will circulate and mix, so ice...

DaveE reacted to Frabjous's post in the thread Other Which branch of engineering is more physics heavy? with Like.
It is too hard to say without knowing at what level the courses are taught and what is offered in the physics department. This is what...

DaveE replied to the thread Other Which branch of engineering is more physics heavy?.But you asked about the convergence of engineering and physics. Engineering is nearly always about devices. Otherwise you'll be stuck...
