The big problem I had with calculus was remembering enough algebra to do the tests. The concept made sense, though even before calc I was having trouble with some of the notation. I know the P/t thing is doing something with rate of change, I just don't know what the symbol means, which would probab...

Today's update, worked on a spreadsheet so I can plug stuff in and tweak things, like max mechanical drive with whatever system I work out, capacitor sizes, etc. Greek is the trouble right now. Some of the letters Woodward uses don't seem to be Greek, or are different forms of the letters than the t...

So "G" should be a constant to look up? That helps a lot. I'd imagine that's what it is, in not seeing any reason he wouldn't be using standard stuff. Now to re-read things again So I can start again trying to parse out where which variables are. Right now it's mechanical drive frequency and electri...

So, found my notes, here's the fun parts, I'm wanting to work to being able to go from knowable quantities such as capacitance(in farads), voltage, acceleration etc. into physical needs and predictions. On page 73 of his book, he has the main equation. Is "G" gravities? I need to look up more on ele...

I have a few questions, having been rereading Woodward's book. I'll have to get notes for a few about equations, but I'll start with a thought for a different thruster design. Put a plain cap stack on a carriage with a a magnet or coil. Acceleration is provided by an electromagnet, much like in a s...

Anarchy is lack of government, not lack of law. Even without government basic laws of human nature still hold, and the slightly more advanced rules needed for a peaceful society dont need a government to enforce them.

This was just a thorium reactor, with boiling zinc as the fuel. I'm not sure that would work, but considering it was first published in 1947, there probably wasn't a lot well known about how reactors work.

It is also probably the first plot involving space nazis.

Reading Rocketship Galileo. How's a thorium- zinc nuclear thermal rocket sound? Weren't the late 40s fun?

You missed my point: Given: Keys to BFR being cheaper than F9 = 1) Full re-usability 2) High volume of launches 3) Re-usability without refurb across 100x launches ...and given: Stated goals of block 5 = 1) Full re-usability 2) High volume of launches 3) Re-usability without refurb across 10x launc...

Just out of curiosity...is it reasonably possible that both EM Drive & Mach Thruster drive will turn out to work? Or are their "theories" of operation in some way incompatible? My understanding is that the proposed theory for the workings of the EmDrive involves rejecting wave-particle duality. In ...

To further explain my position which you quoted, I have not seen (read/heard) of any compelling evidence to date. The primary evidence that sparked the interest 2 years ago came from China. A Professor Yang had published data eluding to high thrust and a possible pseudo-confirmation of Shawyers (ag...

I'm not finding anything on lunar payload mass. I remember reading somewhere it was similar to gto, is that right? I know it's less than leo, but more than Mars. It also sounds like the Roadster was put in it's trajectory from just the two stages? Makes me think you would get some mass efficiency by...

300k could probably build them a "sledgehammer" demonstration unit, with several ounces of thrust far beyond any doubt. A million? Quad thruster drone or something. Wormhole generator? The big thing is to get it scaled better. Get it farther above the noise floor, amd it becomes more solid. And/or d...

So, got the book out of my work bag and looked it up, it's the "Mach guitar" design one of Cramer's students did. Apparently his setup was crap for multiple reasons, but I'm thinking it's worth exploring the setup's potential at least in theory. The tuning fork here could be looked at as a pendulum ...
