Louis Braille was born in France in 1809. When he was just three years old, he accidentally poked himself in the eye while playing with one of the tools in his father's shop. Doctors tried to save his eye, but the wound became infected. The infection eventually spread to his other eye, leaving Braille completely blind at the age of five. When he was 12, Braille learned about 'night writing,' a communication system created by Captain Charles Barbier and used by the French army. It was written by pressing dots and dashes into thick paper, which let soldiers communicate on the battlefield at night without any light. Braille simplified Barbier's system, creating an alphabet that could easily be read by the blind. One hundred years after Braille's death in 1852, his life's work was finally recognized by the French government. To honor him, his body was reburied in the Pantheon in Paris, a special building reserved for French national heroes.

Some of the world's most beautiful places are at risk of being ruined forever. Thailand's Maya Bay, for example, has been shut down to allow the area to recover from the environmental damage it has sustained. Before the shutdown, it had been overwhelmed with visitors, receiving up to 200 boats and 5,000 tourists a day. Due to the litter and pollution left behind, an estimated 80% of May Bay's coral has been destroyed. Boracay, a tiny island long considered an idyllic tourist destination, was also shut down, remaining closed for six months for repair and restoration. The area had been damaged by an overflow of waste and sewage from excessive tourism. Although Boracay has reopened, there are now strict restrictions on tourism. These examples show why tourism is considered a double-edge sword. It can help a region's economy, but it also brings crowds of tourists who may end up damaging the environment.

Air pollution has become a big problem in many urban areas. Trees are considered to be a deterrent to air pollution, so planting more trees within cities is commonly seen to be an effective solution. However, planting trees is not as efficient as most people think - trees require a large amount of land, and there is a limited amount of land available in most cities. This is why City Tree was developed. This innovation, which is capable of filtering out pollutants, is expected to relieve the problem of air pollution. Developed by a German firm, it uses a combination of mosses specially cultivated to thrive in urban environments. The mosses purify the air by capturing particles and absorbing them into their biomass. In order to help the mosses survive under difficult conditions, IoT technology is used to supply water and nutrients. According to City Tree's developers, it can reduce air pollutants in the surrounding area by up to 30%.

Serpentinite is a type of rock that is known for its unique appearance. Its name comes from the unusual pattern on its surface, which is said to resemble the skin of a serpent. Formed deep within Earth's mantle hundreds of millions of years ago, these rocks gradually found their way to the planet's surface. Serpentinite has a slippery texture, and it is composed of high levels of iron, magnesium and water. It has historically been used as a material for constructing buildings for hundreds of years, mostly due to its marble-like characteristics. College Hall at the University of Pennsylvania, for example, was constructed out of serpentine stone in the late 19th century. It is now on the National Register of Historic Places. Because of its beautiful range of colors, including green, yellow and black, serpentinite is also used by artists to make sculptures and is sometimes cut into gemstones.

British runner Roger Bannister set an impressive goal - to become the first person to run a mile in less than four minutes. Because he was studying to be a neurologist, Bannister didn't have enough time for training. He knew he had better come up with a plan. He decided to use a simple 30-minute daily routine to prepare his body and to rely on his self-belief and vision. Bannister used to close his eyes and visualize every moment of the race. He could see the finish line, hear the cheering crowd, and feel himself making history. What separated Bannister from the other runners who had tried and failed was that he truly believed he could do it. He would even write "3:58" on a piece of paper and place it in his shoe before races. On May 6, 1954, all of Bannister's mental preparation paid off. He ran a mile in 3:59.4, setting the world record.
