DaveE replied to the thread High School Why would sailboat racers prefer a full keel over a fin keel?.OK, It's not a great sailboat, and it's not a great power boat. But it is suitable for it's purpose. Jack of all trades, master of none... -
DaveE replied to the thread Undergrad Chua's oscillator circuit -- Intuitive picture.I'm not sure what you mean by "a spike", the circuit oscillates chaotically, so everything is changing. But, generally, you won't get a...

Like.
Re. the discussion about 'reality' of this simulation. If I understand correctly, the beauty of this class of systems is that it is very... -
DaveE reacted to Baluncore's post in the thread Undergrad Chua's oscillator circuit -- Intuitive picture with Like.
That simulations are real simulations, is a truism. Simulators do not model reality, they model a conveniently reductive, idealised...

DaveE replied to the thread Undergrad Chua's oscillator circuit -- Intuitive picture.Simulations can be very valuable when used appropriately. That's the problem; people think it's an easy answer to every circuit...

DaveE replied to the thread Undergrad Chua's oscillator circuit -- Intuitive picture.In the ideal circuit model: The only element that can dissipate energy is the resistor. The negative resistor (Chua diode) can only...

DaveE replied to the thread Undergrad Capacitor Voltages at t = 0: Zero or Split?.If y'all think repeating your position over and over, and over and over, and... will convince the other guy, you may want to focus a bit...

DaveE reacted to Dale's post in the thread Undergrad Capacitor Voltages at t = 0: Zero or Split? with Like.
As we have already discussed, the question is about ##t=0##, not ##t=0^+##. This is simply factually untrue. As the OP already discussed...

Under experimental zero-g conditions where there is no limit on space, time, energy, or materials there would be no limit. Since the...

DaveE reacted to Dale's post in the thread Undergrad Capacitor Voltages at t = 0: Zero or Split? with Like.
As we have already discussed above, all of that is true. But the debate is specifically about the completely unrealistic idealized...

DaveE reacted to pbuk's post in the thread High School Why would sailboat racers prefer a full keel over a fin keel? with Like.
Different posts here have provided parts of the answer, I'll attempt a summary for this specific question: In order to offset the...

DaveE replied to the thread High School Why would sailboat racers prefer a full keel over a fin keel?.This reminds me of a similar story about the old 12 meter America's Cup yachts. A classic yacht designer designed a hull with a fine bow...

DaveE replied to the thread High School Why would sailboat racers prefer a full keel over a fin keel?.Yes, but the information is out there. It's not that hard to find, but it is hard to understand. Fluid dynamics is a complex subject...
