Mass Trespass of Kinder Scout
Peak District ramblers in trouble: walking towards Kinder Scout on the occasion of their battle with the gamekeepers. The mass trespass intended to highlight the denial of access for walkers to open countryside, and some participants ended up in violent scuffles with gamekeepers

Czech Republic - Sokol Rally in Prague 1920s
A rally to promoting public exercise as a way to stimulate national self importance (through organised gymnastic and athletic demonstrations - usually mass-participation). Sokol was founded on the philosophy that a physically fit, mentally alert and culturally developed people can make a nation strong. The word "sokol" translates to falcon and is symbolic of the Sokol ideals: Courage, Strength, Endurance, Fraternalism, Love of democratic principles, and Pride in country. Miroslav Tyrs (1832 -1884) (depicted in the centre) was a key exponent of this approach and is duly being honoured by the ranks of passing Sokol participants. Tyrs believed that a nation must be physically fit, morally on a high plane and intelligent in order to secure independence and retain it. Elevated to Doctor of Philosophy at Charles University and a member of the Education Staff of Rieger's Encyclopedia, Tyrs formulated his Sokol plan, creating an entirely new gymnastic terminology. The next twenty years of his life were devoted to Sokol. He was the first Physical Director, editor of the Sokol paper and creator of calisthenics and exercises, placing the whole system on a firm scientific basis. Between the First and Second World Wars the organisation grew to have a million members. The Sokol programmes were organised to have mass appeal across all strata of Czech society and across all age grous."

Diagram showing the spectral class and luminosity of stars
Diagram showing the spectral class and luminosity of stars. The diagram was named The Hertzsprung-Russell Diagram, or the H-R diagram for short. At the beginning of the 20th century two astronomers found that if stars were plotted on a diagram with their luminosity (brightness) on one axis, and their spectral class on the other, that stars formed three distinct groups. The largest group, the Main Sequence Stars, is where 90% of the stars are found. These stars are fusing hydrogen into helium in their cores. This group propagates diagonally from the upper left corner, down to the right corner. The group below the main sequence is the White Dwarfs, which is a group of small, earth-sized stellar remnants. The third group, which is found above the main sequence is that of the giants.
Stars appear on a specific place on the main sequence depending on their mass and age. The mass determines when it will leave the main sequence.The H-R diagram is a significant tool for astronomers, when it comes to understanding stellar evolution
