The tread in the philosophy forum describes theories of why consciousness seems to go in the same direction as other arrows of time: https://www.physicsforums.com/showthread.php?t=124119 The T-asymmetry that we observe in the Universe is not explained, any more than why E=cmc is explained--it...

Umm. Two things: 1) If time flows symmetrically, then why would an observer only remember the "forward" flow? Shouldn't it be possible for an observer to live in the symmetric flow and remember only the "backward" flow? 2) Entropy increases in a CLOSED system. If you draw a box around the...

Of course, the equations are more easily shown to work with something simpler than a human, more like an electron. A closed timelike curve is not a paradox. It is more like traveling into the past to save a grandfather's life! This is because of the fact that the curve is closed; you wind...

Add a variable for what you want to show is invariant. Show that it makes no difference in the equation. For instance, derivative of a function is invariant with respect to a constant added. So you make the constant an independent variable. Take a derivative. Notice that the derivative of...

There are many representations possible, such as a 3x3 matrix of two-dimensional elements, the first being dimension being the set of integers 1 through 9 representing each piece, and the second being the set of integers 1 through 4 representing the four rotational possibilities. You can...

Space is an embedding metric of the distribution of mass and energy. Space, itself, is not energy, but contains energy. The volume of space enclosing a black hole contains much more energy than the same volume of space in an intergalactic area with little mass in it.

There are four principles of adhesives briefly described in: http://ezinearticles.com/?In-English,-Doc!-How-Do-Adhesives-Work?&id=1448917

http://www.bioedonline.org/news/news.cfm?art=2531" Take a look at http://dcwww.fysik.dtu.dk/~tbohr/RotatingPolygon/index.html to see water swirling in a cylinder spontaneously for hexagons and other polygons--it seems plausible that the hexagonal shape on Saturn's north pole is formed by...

An (n-1) polynomial will hit all the points, but is unlikely to be useful for interpolating or extrapolating experimental data, because often such curves will contain maxima and minima far outside the range of recorded values. If you eyeball the type of curve you expect to see, and count the...

The factorial does not have an inverse, since 0!=1!=1. The gamma function also does not have an inverse. However, by restricting the range of the factorial function (as is done for the standard trigonometric functions, sin, cos, etc.), we can define the inverse of the principal branch of the...
