BIBO - A Standard for Stable Currencies
BIBO - Bounded-Input-Bounded-Output is an engineering term. It comes from Control Systems Theory and signifies that any system, to be stable, must respond to a bounded input with an equally bounded output. Our system of bank currency - the money we are using every day - has a fatal design flaw - it violates the BIBO principle. Economic instability is built in to our money right from the start. This leads to the imperative that the economy must keep expanding endlessly. We are unable to achieve sustainable economic activity, to preserve our planet's finite resources, lest we face financial collapse. This, in short, is the situation as argued by Marc Gauvi

Global Climate Change: The Arctic Deep Time
Global Warming or Climate Change is a reality, we are being told, it is something we must deal with if in the near future we don't want to see the earth become inhospitable to life. And Global Warming is being brought on by humans burning oil and coal. It is the increase of carbon dioxide in the atmosphere, a gas that transforms our planet into a greenhouse, destined to warm up until we stop burning those fuels. "Cap and trade", is the way to reduce emissions to levels that will stop the inevitable warming up of the planet. No more increase in fossil fuel burning except ... if a country can pay for the right to continue emitting carbon dioxide.

The End of Money and the Future of Civilization
Large parts of the economy appear set to go to hell in a handbasket. The banking system, which should be of service to production and the economy, is itself on the verge of collapse. Yet the speculators who brought down those banks are being lavishly rewarded - bailed out with huge gifts of our hard-earned money. Unless we want to spend the rest of our lives working to pay off those huge debts, we must understand what exactly has been happening and why - where things went wrong. And we must figure out how money and b

Rattleback 'mystery' explained
A rattleback, also called a celt or wobblestone, is an interesting little piece of material with a roundish bottom and an unbalanced distribution of weight. When spun, it will soon start to rock and then, as the rocking motion subsides, it will settle down to spinning in the reverse direction. Rattlebacks do not work well on a slippery surface, which means that a certain amount of friction is a necessary condition for it to work... There are several videos on YouTube that show the spin reversal we see in a rattle

Extended Michelson-Morley Interferometer Experiment
The original experiment of Michelson and Morley was performed in 1887 in order to confirm the theory that says earth exists in an unseen sea of pre-matter called the aether, and that the daily rotation of the earth around itself and the constant travel of the earth around Sol, our sun, would expose any instrument on the earth's surface to what was called an "aether wind". The concept is that the aether, conceived as the medium that allows light waves to travel from one point in the cosmos to another, would influence the measurement of the length of a path of light, depending on whether the path is in
