Carbon fiber, 3D printed parts, multiple rotations. Numerous small refinements of the design to get to a 776 mph release. Your castle... -
DaveE replied to the thread High School XOR operand distinction.## A \overline B ## is as good as you will get IMO. You might also have to test for ## \overline A B ## to exclude the ## \overline...

DaveE replied to the thread Undergrad "Is Kirchoff really for the birds?".Yep. Ask anyone that's ever done a PCB layout for a SMPS or high speed digital if the schematic tells the whole story. YouTube creators...

DaveE reacted to weirdoguy's post in the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same? with
Like.
It has been discarded from modern quantum physics a long time ago (even though pop-science still talks about it). It has been discussed... -
DaveE reacted to Averagesupernova's post in the thread Undergrad "Is Kirchoff really for the birds?" with Like.
I watched the video posted at the beginning of this thread and I admit I did skip through parts of it. I will likely watch it again at...

DaveE replied to the thread Undergrad "Is Kirchoff really for the birds?".I'm reminded of a favorite quote from, maybe, the best analog EE prof ever: "Engineering is the art of approximation" - R.D. Middlebrook...

DaveE replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.Interference is just a consequence of vector addition. You'll also see it in water waves in a harbor. Lots of things are well modeled...

DaveE reacted to Baluncore's post in the thread Undergrad "Is Kirchoff really for the birds?" with Like.
In order to profit from comments and corrections, they have knowingly and deliberately, got it wrong. Every "view to the end" pays them...

DaveE reacted to pasmith's post in the thread High School Uncertain about part of the Order of Operations, from a formula with Like.
Exponentiation has precedence over multiplication.

DaveE replied to the thread High School Uncertain about part of the Order of Operations, from a formula.Brackets that don't include an operator are meaningless. (a) = a. First step, remove them. so, V=((H/100)^(a)*(b))+(c)=((H/100)^a*b)+c...

DaveE replied to the thread Undergrad "Is Kirchoff really for the birds?".I would bet that the people making these videos know the answer just as well as we do. I think they are playing up the mystery for...

DaveE replied to the thread Undergrad "Is Kirchoff really for the birds?".I think there's a broader issue on display here which is often neglected and not well taught in introductory physics. CIRCUITS AREN'T...

DaveE reacted to kuruman's post in the thread Undergrad "Is Kirchoff really for the birds?" with Like.
And the reason is that KVL is ##\oint \mathbf E\cdot d\mathbf l = 0## in disguise. Electric fields due to induced voltages are...

DaveE reacted to DaveC426913's post in the thread Options for fixing power connector on Acer laptop with Like.
Thanks everybody. A 65W USB-C charger has done the trick. I now have a perpetuitous, non-proprietary solution. Whatever it is that fails...
