Notice that each of those clumps is arranged like this: ball, ball, ball, magnet.

When a ball is sucked in to the magnet from the right, it's getting pulled right up next to the magnet so the magnetic field has the most effect on it. The shockwave from the ball striking is transferred through to the next balls in line, like a Newtons Cradle. The 3rd ball is far enough away from the magnet that the force of the strike greatly outweighs the force, sending it flying away at great speeds. The line repeats this process 3 times to build up the effect

That irrational orbits don't repeat, or that our solar system does not have a rational orbit.
The first is obvious - you assume that the orbit repeats and show that the length of the orbit must be some fraction of the time it takes to repeat. To show that there is zero probability of it having a rational orbit follows from the the fact that the rationals are countable and the reals not so much.

However, your memory vs. imagination note is very interesting in itself, I've never gave it thought, but it's clear to see that the higher your social rank, the more you lean on memory, memory of your achievements. The lower it is, the more you lean on your imagination, classical loser rationalisations (well, at least I'm the nice guy, I did the right things, I'm gonna laugh in heaven at those jerks, looking down upon them burning in hell). Also imagination vs. memory correlates with introversion and extroversion, the limits of which are indeed autistic and anti-social people. The first define themselves by their inner world, while the latter don't really have the inner world to speak of and define themselves exclusively through their achievements (people in between would get lesser achievements, but would get more satisfaction from them, because of respective serotonin levels).

There is very little money in topology. The place where the most money and research is being done in the mathematical field is economics.

But this is not true.
There are currently way more theories to be tested than experiments done to test them. In other words, we lack experiments and have too many theories.
Also, the large collaborations (CERN etc) can be seen as big experiments on which thousands are working. Of course they have theoreticians working with them, but it's mostly to tune a little what they already predicted.
What about the fact that predictions come way before the actual tests (gravitons..)? Would you say these experiments are not cutting-edge?

yes. it comes from the failure of the decimal system to realize infinity.
duodecimal system illustrates the equality much more cohesively.

$zdxdy=$kzdz

Not true.
For an otherwise vacuous spacetime with classical electromagnetism,
<div class="math">R_{ \mu \nu } \propto F_{ \mu }^{ \kappa }F_{ \kappa \nu }- \frac {7}{8}g_{ \mu \nu }F^{ \alpha }_{ \beta }F^{ \beta }_{ \alpha }</div>where <span class="math">R_{ \mu \nu }[/spoiler] is the Ricci curvature tensor (the curvature of spactime), <span class="math">g_{ \mu \nu }[/spoiler] is the metric tensor, and <span class="math">F_{ \mu \nu }[/spoiler] is the electromagnetic field tensor.

but it is? it's just half-filled d/f orbitals that arrange in an order resulting in an angular difference in electronic charge distribution instead of willy-nilly distribution or even placement

You may be right, pedant, but you missed the point of the post you're responding to. The curvature that results from typical magnetic fields is trivial. Magnetic forces operate very differently from space time curvature (unless you're assuming some Kaluza Klein compactification).

> New Derivation of the Ground-breaking "Trickster"-formula

Actually, Ramanujan did derive it earlier, but it wasn't as elegant (inb4: implying anything Ram has ever done is elegant). Jacob proposed to call it "Trickster" formula, because of how many mathematicians were confident it's wrong initially.
In the conclusion Barnett writes, that implications of this maths piece may indeed be followed by some unforeseen consequences. Perhaps, this equation will bring back the need in God into science? Or even disprove the fact, that c is maximal speed in vacuum?..
