    Testing Philosophy

    We rake Christina over the coals on what they offer as evidence and proof of claims. Should philosophy be any different? Or is philosophy similar to theology? Is philosophy in general as subjective as religion? On the never ending debate on free will is there an experiment that proves or...

    Correlation With Python

    ...so the product is always positive. When signal components and correlation points do not match in sign the summation is zero or close to it. w = 2*ma.pi*fr[f]/n divides the sine curve of the correlation function into n pieces. for j in range(ncor):s = s + y[j+i]*ma.sin(w*j) does the...

    Rastafarian

    It is intersting how a dead African political leader became a messianic fugue to Rastafarians. Perhaps how an HJ became levated to a messiah by non Jews shortly after he would have lived. Ratafarin is bible based, adope and coopted to fit the needs of a downtrodden minority...

    Gender Roles

    The 'battle of sexes' has been a theme throughout human history. I do not know if the term is still used. It also includes gender neutral hair styles and dress. A prevailing attitude has long been women and gays for that matter should be who they are without bias, but not hetero men. A social...

    What is capitalism?

    Like most political terms the meaning of capitalism changes and needs context. There are positives and negatives to free market capitalism.

    Encoding Numbers

    A Gray Code is a binary code that changes only 1 bit at a time. One modern usage is in rotary postilion encoders. Shining light through holes in a disk with straight binary is problematic, had to unambiguously determine multiple simultaneous bit changes. A simple math technique with wide...

    The Biblical Flood Caused An Ice Age

    I don't know who's who in creation science but I heard this in passing on a radio show, Heard this in a Chi stain show. 'Secular' science says there is evidence that there have been multiple ice ages, but they are wrong there has only been one. And it was caused by the biblical flood. It goes...

    What is social science?

    There is hard science and soft science. Physics is a invariant hard science. Psychology which has an experimental basis is a soft science. It can be based on statistical inference, but there are no deterministic equations and variables as in a hard science. Hard and soft science both use the...

    The Jesus Cult Of Pain

    A bloody Jesus on a cross in agony wearing a crown of thorns represents a cut of pain and suffering. There was a large such a crucifix hanging over the alter in the church I went to as a kid.
