Vallis | Video Esssays: The Irony of the Dunning-Kruger Effect at https://www.youtube.com/watch?v=kcfRe15I47I This is a common curve in electrodynamics where the descending region after the peak, is said to have “negative resistance” There are quite a few places where it shows up where variable resistance is possible. There the axes are voltage (Volts) or pressure

I design an electromagnetic field launch facility that lift the Starship second stage to its mission height and velocity on the planned time schedule ( a few minutes). It completely eliminates or replaces the booster. More importantly it also can catch and gently set the returning craft back in its cradle. So the overall size

Subject: Found the derivation of the gravitational energy density in a workable form Ben, Most humans live in little bubbles and are only vaguely aware of the whole. So global policies, issues and opportunities are made up by many billions of people acting independently. Or for “smaller” policies, issues and opportunities – millions, hundreds of

Archer.com Adam Goldstein, I saw your ad on Twitter (now X) promoting Archer. I read some of the website, but had to ask Google Bard for specifications on your craft and battery and motors. Your site is too glossy for me. Now people who might want to use VTOL are likely to be efficiency minded.

Plasma Channel: Designing A Next-Gen Ionic Thruster! (For Flight) at https://www.youtube.com/watch?v=nrEBoPYS4ns The stagnation pressure is (1/2) * AirDensity*Velocity^2. And the power goes as the cube of the velocity. So using velocity increments is not exactly the best measure. At least get yourself a spreadsheet or HTML/Javascript and have it keep track of the velocity, squared velocity,

Master Ivo: Field Propulsion, Explained with Working Proof at https://www.youtube.com/watch?v=lVjC47NBqfM You are wasting a lot of time inventing theories that are well known and trying to learn quantities that are relatively easy to measure and calculate. Start by thinking what you want to do. I suggest you use magnetic levitation first. Forces on wires and magnets

Richard Behiel: The Nature of Gravity, Part 1: Earth’s Potential and Acceleration Fields at https://www.youtube.com/watch?v=zjBo58RxYQ8 Richard Behiel, I like your animations, they are a help for visualizing. You might want to consider all the mass from the sun, cosmic rays, solar wind, meteorites, dust and things that collide and interact with the earth over billions of

The Action Lab: Magnetic Locking WITHOUT a Superconductor! at https://www.youtube.com/watch?v=V5FyFvgxUhE Fantastic. Now do some measurements, write some equations and write some software so people can plug in what they have and get estimates of what regions will be stable. Or give specifics of separation distance, mass and force, to calculate what speed to use and what

Susumu Komiyama, I was looking for your paper, “Electron temperature of hot spots in quantum Hall conductors” and found this THz imaging paper on ResearchGate. I think at zero temperature the magnetic energy density and its gradients are important. “hot spots” are just part of it. I was looking at ways to push the fields
