    What does statistically significant mean?

    That's really clear...

    Proof of this limit formula for e

    The above "solutions" are all tautologies. They all assume that e exists and is the base of natural logarithms. Now, this is true, but the proof of this is outlined at http://planetmath.org/convergenceofthesequence11nn, I have found no other site with this proof. Essentially done in two...

    B Suspended Mass

    Just to note that the F-4 (Phantom Jet) of the 1950s and later, which looked like a brick could fly because it was given enough power.

    B Suspended Mass

    Thank you, Nugatory I think "I've got it." If the "mass" were kept aloft by an airfoil (vertical lift generated by horizontal motion), i.e., translating induced drag to vertical lift by the airfoil, is theoretically possible with a super large airfoil of no weight itself to generate large lift...

    B Suspended Mass

    Is there any way to convert horsepower into pounds thrust?

    Don't want to start a "fight."

    B Suspended Mass

    Aware that work done on the mass is zero. BUT it won't stay up on its own. Where does the force come from? How is it generated?

    B Suspended Mass

    Still, no answers posted. Only vague generalities.

    B Suspended Mass

    To maintain a 550 lb mass in the air not touching the ground at sea level (radius of Earth is 4000 miles), what is the expenditure of energy required given perfect efficiency of the process?

    B Does red-shifted light cause expansion of space?

    @phinds - Never thought of that.

    B Does red-shifted light cause expansion of space?

    Red shift is a result of the expanding universe, not the cause of it. Basic Doppler wave mechanics. Must keep the cart and horse in the right order. Question is did the original singularity have infinite energy? This is possible mathematically (1/zero). If it did, the universe will never...

    Tissue transplantation

    I hate to use the Internet as a reference but this is a simplistic one. It paraphrases what the more technical references state: Home Treatment / Support Long-Term Follow-Up Frequently Asked Questions Understanding graft-vs.-host disease ShareLONG-TERM FOLLOW-UP Understanding...

    Tissue transplantation

    Works the other way. The tissue that does the reacting is the donor tissue (the female tissue.) Hence the F > M transplant will result in a greater reaction (GVH.)

    Tissue transplantation

    Sounds like GVH disease would be more common in F > M transplant due to extra X and more potent immunologic response by female tissue and T-cells.

    Tissue transplantation

    How can one transplant a (donor) tissue to a recipient allograft and have it "take" if the donor and recipient are of different sex? They are automatically genetically different which can never be broached.
