Indeed, a post calculated -- and I use the term loosely -- to strengthen the illusion that Vixen is competent in physics without her having to display any actual skill at the subject.
Of course there are proofs of Archimedes' discoveries, and not just his work in displacement and buoyancy. The most satisfying proofs are empirical. Similarly there are many ways in which one can try to prove one is competent in physics. But the only one that matters is the empirical one: one actually has to be able to do physics. Telling dubious stories about her prowess at school, the praise of her teachers, etc. simply will not substitute.
A fair amount of Vixen's claims either base themselves on physical science principles, or are testable by those means. She's hitched her wagon to a claimant, Anders Björkman, who she believe has her back when it comes to science; she can just parrot what he says and no real scientist would be able to argue against it. But when it comes to science, the man is an obvious crackpot with no discernible skill at physics, or at best no discernible desire to represent it accurately. What's more important is that her critics have the knowledge and skill to see this for themselves while she's still wallowing in ignorant bluffs. Her critics also have the knowledge and skill to know -- not just guess or suppose -- but to know that she don't have any idea what she's talking about when it comes to the physical science portion of her claims. That knowledge is not going to be displaced by her nostalgic recollections of questionable authenticity.
She keeps peppering us with ill-conceived questions such as how a ship can "float on its superstructure." She considers it an unshakable article of faith that any ship, once it has passed its angle of vanishing stability, will turtle. She stumbled across a lecture presenting some of the elementary principles of transverse stability, but she don't seem to actually want to learn about the subject. She's using scientific references as opaque, magical incantations to dispel criticism, not as tools to help learn about the way the natural world behaves. If she expended half the effort she spends in pretending to be right toward actual learning, she might be happier in the long run even if it means shedding some of the counterfeit pretense to erudition along the way.
