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...

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...

...domin function that matched your circuit and read the time domain solution. The differential equations for a capacitor and induct or are i = C * dv/dt v= L* di/dt. The equations represet energy storage in magnetic and electric fields. Adding parasitic resistance for the induct or and...

Like most political terms the meaning of capitalism changes and needs context. There are positives and negatives to free market capitalism. On the plus side all the technology from refrigerators to computes evolved through a competitive process. IBM is still here. Digital Equipment Corp, Daisy...

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...

A Christian paid TV program is running, it is Sunday after all, on biblical interpretation predicting a battle for The Red Sea. A German 'strong man' will soon to take over Europe ad lead an attack on Iran. https://www.thetrumpet.com/28737-the-battle-for-the-red-sea Christisn, Muslim, and...

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...

Working solutions to c;calculating math functions.

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...

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. Around the church were the ;stains of the cross'. A priest in full regalia with a scepter followed by...

My only experience with Bahai was a couple. What they talked about is victimhood, how they are persecuted for their beliefs. Victims of persecution for beliefs Christians Muslims Jews Baha'i Hindus Sikhs It seems persecution by an adversary is a key element to religion. Us vs them. In the...

A response to a post on another thread. In the 90s when I took a night class in modern physics it was a little anti-climactic. Some of the general principles I understood from elect cal theory. Principles of resonance and complex impedance are a general form that appear in electric circuits...

Branching from a post on god of atheism... If it is in the bible it is moral, of course. Morally objective and absolute? Does not pass the laugh test. There is widespread Christian support for an ethically and morally repugnant Trump. Moral relativism. Christians openly say they know it but...
