I meant this family thread. 
And what is Mayday? 
Can someone give me few points on astarmathandphysics.com ?
May Day occurs on May 1 and refers to several public holidays.
In many countries, May Day is synonymous with International Workers' Day, or Labour Day, a day of political demonstrations and celebrations organised by the unions, anarchists, and socialist groups. May Day is also a traditional holiday in many cultures.
The happy idea of using a proletarian holiday celebration as a means to attain the eight-hour day was first born in Australia. The workers there decided in 1856 to organize a day of complete stoppage together with meetings and entertainment as a demonstration in favor of the eight-hour day...At first, the Australian workers intended this only for the year 1856. But this first celebration had such a strong effect on the proletarian masses of Australia, enlivening them and leading to new agitation, that it was decided to repeat the celebration every year.
