A heat can only be generated by a system, if the system contains some kind of motion in its elementary/fundamental structure. As I explained also, there are no two ways around it, if you speak about heat energy you must be referring to motion within the system!!!

Now, if you remove all visible matter and energy from a square measure of space, you will find that...

A plane flying straight ahead through the air doesn't have to account for local topography by moving up and down like you on the surface have to.

This is because:

* gravity smooths out the plane's local frame of reference;

* the atmosphere smooths out the plane's local frame of reference;

* it's for the same reason you don't have to...

What's gravity good for?]]>

The geometry of the gauge field (read: field of phase changes) concerned looks like a truncated cone capped with a spherical dome.

That means, there is a hemisphere which has a line of latitude extended to a surface with constant curvature. So the bundle of fibers from that circle of latitude and lying over the conical surface (a section of the total space), has planes...

\(E = m\dot{R}^2 = \frac{8 \pi GmR^3}{R}(\rho - mR^2 \omega^2 + mc^2 \Lambda R^2)\)

In which a Lagrangian can be derivable by setting the equation to zero

To get a rotation term in the universe may seem like an assumption that the rotation term enters the equation with a...

Are we missing a rotation term in the Friedmann equation?]]>

They cite that If you deposit 10k you get 0.79 every day. What are the actual effective yearly benefits in %? Is it 3%? More? Less?

Time comes back in all areas: mathematics, physics, philosophy, in our everyday life etc ... But as soon as we try to define it, we arrive at problems. Is there time? The problem of time contrary to the coordinates of space-time is that it escapes all our senses. Now, the axioms of mathematics and the physical...

That number is, rather famously, n! (say "n factorial"). And we have a number of ways to write it.

\(\textrm{card} \, S_n \equiv \textrm{card} \, \left\{ f \, | \, f : \textrm{ordinal}_n \xrightarrow[\textrm{onto}]{\textrm{1-to-1}} \textrm{ordinal}_n \right\} \\ n! \equiv \prod_{k=1}^{n} k \\ \Gamma ( n + 1 ) \equiv...\)

What follows is my intuitive understanding of gauge theories, though I do have a lot of the relevant geometric mathematics to hand if it would interest anyone - from a purely mathematical viewpoint it is quite nice.

So, a physical theory is said to be gauge invariant - loosely a gauge theory - if it takes the same form under local continuous symmetry transformations. Since continuous symmetry transformations are given by some Lie group \(G\) - presumably specific to the...

Here's some sample data:

The equation needs to have a horizontal asymptote at about 212°.]]>
