Model Trains

Here are some images I recently took from a Model Train Convention :) Here are some model trees: Here are some model buildings: Note - this last display from 2020 Hobbies had oscillating and rotating parts.

Martian Dry Ice Craters


The following is a 3 phase water diagram with a 3 phase carbon dioxide diagram superimposed over the top: At moderate room temperatures (60F - 100F) carbon dioxide can build up to dozens of atmospheres of pressure (14.7 psi = 1 atm). Tire pressure is about 3 atmospheres or 40 psi, and most air compressors that pump tires can achieve about 15 atm or 180 psi. If an air compressor explodes that makes a big explosion, now consider how CO2 gas can build up to about 80 atmospheres of pressure before 2 phasing or beginning to liquidize (see chart above), an explosion of that magnitude would likely create "bomb" craters on Mars. Theoretically Mars past consisted of an exponential decay of such crater formations if it once was covered with dry ice.

Atmospheric Gas And Bouyancy

Icebergs float because ice is less dense and therefore more bouyant than water. However, bouyancy doesn't occur in freefall because there is no gravitational field to generate up or down, so ice cubes would jumble around in a glass of water every which way according to brownian motion. There needs to be a change in momentum to cause a less dense material to jumble on top of a more dense material which occurs naturally in the presence of gravitational or acceleration fields. Buoyancy is also caused by less massive objects bouncing faster and further than more massive objects given the same level of impulse or force being applied over time. In air, millions of molecules are jumbling and bouncing around in a gravitational field, and satistically the lighter masses end up higher than heavier masses. Earth is an open system and thereby is exposed to the light, shadows, and reflections from the sun, and many different molecules absorb many different wavelengths and get different levels of impulses than other molecules do which causes weather and climate patterns. So you can in fact get the paradox of more dense gasses at higher elevations than lighter gasses, but over time bouyancy should still equalize the distributions.

Circuit Resonance

The following shows a Simple Resonant Circuit (SRC) on PSpice:
Here the SRC is supergenerated by an operational amp then boosted by a transistor amplifier producing tones out a speaker:

Special Relativity

What happens if a ball is traveling at a universally constant speed, say measured to be 50 mph straight up relative to the people on a bus thats moving 40 mph relative to a sidewalk, but also measured at 50 mph at a 3-4-5 triangle relative to the people on the sidewalk?
In that case the ball exhibits a "special relativity" as it travels at a constant speed relative to all observers, which means either time is technically dilated or the bus length is technically shortened:
This phenominon of Special Relativity time dilation has been shown to exist for the decay times of particles in atom blasters:

Gravitational Collisions

Here is a representation of elastic and inelastic collisions using an experimental air track system and collision magnets: Here are the initial steps for reducing a 2 dimensional elastic collision down to a 1 dimensional elastic collision: Here is an example problem of the additional steps for solving a 1 dimensional elastic collision: Here is my own depiction of the dynamic gravitational forces on a rocket performing a planetary flyby: This shows the way in which a gravitational interaction can be modeled similar to a collision with the center of mass at the more massive body (gravitational collisions are a more complicated process as linear and angular momentum as well as gravitational kinetic energy may or may not be conserved all depending on the specific parameters, perhaps aerobraking or rocket propulsion are taken into account, and other effects such as magnetic forces and light or plasma radiation play an effect too depending on the circumstances): Here is an artist's depiction of the longterm gravitational trajectories that asteroids tend to take as they interact with planets and moons:

Q-BYTE

A Q-BYTE is a quantum byte that exists in a superposition of all states simultaneously:

Notice all the reflection and rotation symmetries: Highly useful in MATRIX Programming Languages.

Optic Refraction

This shows the dispersion of white light through a prism at various frequencies. The higher the frequency, the more the light gets refracted. As seen below, the further light travels through a medium, (1) the more absorbed it gets and (2) the more it travels in the direction of refraction. This is also analogous to what happens when light travels through a planetary atmosphere or refracts off the interstellar medium from the light escaping from entire galaxies. Could a cosmic redshift be caused by a universal low pass filter?
