b'SIGNIFICANT MOMENTS THE BEST THING SINCE SLICED BREAD!It is very difficult to choose one moment or event that changed the world, even when you can narrow it down to just the last 160 years! A moment so significant that the world would never be the same again. Do you choose a scientific or technological breakthrough? Antiseptics, heart transplants, chemotherapy an endless list of life-saving medical breakthroughs all post-date HGS. One giant leap for womankind meant women were given the right to vote in 1928many years later than men were awarded the same privilegeand truly a significant first-wave feminist moment. Is it more significant than the birth of cinema or popular music, the invention of the television, the car, the NHS, space travel, the internet?While you ponder which one you would choose, here are the views of the staff of HGS.ArtI would say the invention that changed the whole meaning and practice of art was the development of photography and the commercial use of the camera.Prior to this, the function and role of the artist was to represent reality. They painted portraits, landscapes, and items to reflect what they were seeing. With the invention of the camera, artists no longer needed to slavishly copy nature and could explore other aspects of art such as emotions, the use of materials and personal expression. This led to the development of the various -isms, starting with Impressionism in the 1870s. The most significant and challenging of these -isms was perhaps Cubism. It is still a huge influence on artists, designers andPhysicsarchitects to this day.Modern art has always provided a commentary on life and life events and has had an impact on everything from crockery, buildings and furnitureThere are so many branches of physics that it to the production of political, evocative andis difficult to highlight one specific idea but, if satirical images that make us really consider ourpushed, I would suggest Einsteins Theory of own opinions and beliefs. Special Relativity (published in 1905). In this he Ms Fisher generalised Galileos Principle of Relativity (that all uniform motion is relative, and that there is no absolute state of rest) from mechanics to all the laws of physics, and he incorporated the principle that the speed of light is the same for all observers regardless of any relative motion between source and observer.Interestingly, when he endeavoured to extend his theory to include gravity and make it genuinely universal he introduced a cosmological constant, in effect as a fix to make his theory work. He later described this as his greatest blunder We all make mistakes!Mr Jones60'
