DaveE reacted to Baluncore's post in the thread How Far is Due East From Due West on Earth? with
Like.
Rudyard Kipling answered the question in 1889, with: The Ballad of East and West. " Oh, East is East, and West is West, and never the... -
DaveE reacted to Danieldsouza's post in the thread Embedded Engineer Exploring and Contributing to the Community with Like.
Hello everyone, My name is Danieldsouza, and I’m an embedded engineer with over 10 years of experience in embedded systems and...

DaveE replied to the thread Danish Scientists.At least to add Niels Bohr, he was about as famous as you can get in Physics.
-
"Due east" and "Due west" are directions, not locations. So there is no distance.

DaveE replied to the thread How Far is Due East From Due West on Earth?.How far is up from down?

DaveE reacted to Baluncore's post in the thread Extracting capacitance and inductance from s-parameters with Like.
If you are designing a PCB for operation over a narrowband, then your S-parameters will be for frequencies specified on both the low and...

Time to invest in a dedicated pair of single-focus computer work glasses. Your health is worth it. :smile:

DaveE reacted to Baluncore's post in the thread Undergrad Diodes and low grade thermal energy harvesting with Like.
Solar panels do not work in the dark. They are designed to operate at visual wavelength, in sunlight. Indoors, there will be thermal...

DaveE reacted to anuttarasammyak's post in the thread Undergrad Finding the minimum distance between two curves with Like.
Yes, after we check that the curves do not cross at first. We may include not smooth points and end points on the curve in the survey...

DaveE replied to the thread Undergrad Finding the minimum distance between two curves.Yes, as long as they exist and are unique. Otherwise you will also have to find the best one, like other min/max problems. There's...

DaveE reacted to anuttarasammyak's post in the thread Undergrad Finding the minimum distance between two curves with Like.
Find the two points that share the same normal line. It would be a general way as @pasmith showed.
-
You may be misunderstanding unique in this context. It doesn't mean that you can not produce the same subsets in different ways. What it...

DaveE reacted to Charles Link's post in the thread Undergrad Finding the minimum distance between two curves with Like.
@DaveE These two are no longer identical parabolas, but I believe @Gavran 's method will work for them. I'll try to post the result...

DaveE reacted to Baluncore's post in the thread Interpreting VIA PCB characteristics through TDR and TDT with Like.
TDR is a plot of impedance (driver voltage) against reflection time. Z = √( L / C ) You cannot say if it is the inductance or the...

DaveE replied to the thread Undergrad Finding the minimum distance between two curves.Excellent! Symmetry again. What about the curves y=4-x^2 and y=(2x-3)^2? Or y^2=x and y=(x+10)^2? I've given this zero thought, but I...
