    High School Ideal Base for a Number System

    I would propose binary, but use hexadecimal for communication numbers in writing.

    Undergrad Universe from Nothing: Cosmological Theory Explained

    Here are a couple of more mainstream ideas: http://www-personal.umich.edu/~huterer/PRESS/CMB_Huterer.pdf http://arxiv.org/abs/1201.2459

    Undergrad Gravitational Force/Earth Rotation Question

    Might it be more accurate to say it is a mathematical consequence of having radial motion in a rotating coordinate system? This is why it is often referred to as a "fictitious force" in the Newtonian system.

    Undergrad What Causes Jets to Entrain Mass?

    Fluids are treated as continuum mechanics. The jet has to displace air in its path, right? So it is going to transfer some energy/momentum.

    Undergrad Energy from cosmic microwave background

    Unfortunately you indicated a volumetric density. I think the number is reasonable though as https://dspace.carthage.edu/bitstream/handle/123456789/37/Adam%20Ferg.pdf?sequence=1 states ~10^-14 W/m^2.

    Graduate Gases that absorb IR radiation

    For atmospheric gases, water may be the best bet. http://thermal-imaging-blog.com/wp-content/uploads/2011/08/snellblog08-03-1.bmp

    Undergrad What Causes Jets to Entrain Mass?

    Free jets emanate form an orifice and are traveling at much higher velocities then the surrounding fluid (lets say air jets in air). The interface between the jet and the surrounding air needs to be at the same velocity, so the jet has to accelerate the nearby surrounding air to satisfy this...

    Undergrad Universe from Nothing: Cosmological Theory Explained

    Read this, and see the movie, and let Krauss and the others in the documentary explain it.

    Undergrad Universe from Nothing: Cosmological Theory Explained

    He said the implication of the WMAP data (and this now extends to Planck as it has reproduced the observations) are that we are truly in the center of the universe. Take it as you will. See the movie where he talks about it. You are presuming form your understanding what Krauss said.

    Software for learning structural analysis and FEM?

    Most universties have Ansys, some have Abaqus. I believe both Autodesk and Solidworks student versions have some FEA in them.

    Undergrad Universe from Nothing: Cosmological Theory Explained

    Lawrence Krauss discusses this in the film THE PRINCIPLE. He also discusses his statement that the implications for evidence from the WMAP satellite indicates that the Earth is "truly in the center of the universe".

    Undergrad Does The LCDM Model need reworking?

    You should watch the movie The Principle. It discusses the issue of the cosmological/Copernican Principle, and features Lawrence Krauss, Max Tegmark, Michio Kaku, George FR Ellis, Julian Barbour, Bernard Carr and others (narrated by Kate Mulgrew, aka Captain Janeway of Star Trek). And yes it is...
