Among twelve similar coins there is one counterfeit. It is not known whether it is lighter or heavier than a genuine one (all genuine coins weigh the same). Using three weighings on a pan balance, how can the counterfeit be identified and in the process determined to be lighter or heavier than a genuine coin?

These spheres would be intimate mixtures of positve abd negtive matter, perha[s in a co-tetraheedral configuration. All over the surface sandwiches of positive and negative matter in the shape of plus signs would form. Each one would repel its four nearest neighbors. They would grow into tall filaments. Finally, they become rockets accelerating radially outward until they encountered filaments from other cosmic eggs. Vast chaotic zones would come about. I saw a picture of deep space in the Smithsonian which seems to show this.

I've heard that in the mediterranean shores of France speak a different language (a sort of Spanish/Italian mix) and is populated with black haired latin people, different ethny than the gallic/Germanic tall/blond-haired peoples of France.
Those regions also have a very different culture, climate and a complete different architecture from France too.
Why nodody does not do nothing to liberate those proud latin peoples from the Gallic colonisation ?

I recently read an article that stated the speed of light had been exceeded by transmitting data faster than the speed of light by a factor of 5x. I thought it would be really exciting news because of the laws of physics. It would mean the constant for time would be more of a variable than a fixed number.
