One hundred seventy years ago, tuberculosis was a lethal disease. This illness posed a significant threat to humanity, resulting in an estimated 1 billion deaths between 1700 and 1900. Notably, traces of tuberculosis have been found in the mummies of ancient Egyptian kings. In the late 1840s, German botanist Hermann Brehmer, confronted with the fatality of tuberculosis, relocated to the Himalayas in search of fresh air. Remarkably, he survived and is believed to have successfully fought off Mycobacterium tuberculosis in that less favorable environment for bacterial growth. As a result, numerous nursing homes emerged across Europe and the United States, including specialized facilities for tuberculosis care and luxury accommodations for the affluent. However, by the 1940s, many of these nursing homes began closing due to the emergence of antibiotics, which drastically changed their economic viability. Throughout history, it seems that economic value often proves transient. - Joseph’s “j...
The tallest mountain in the solar system is Olympus Mons on Mars, towering about three times higher than Mt. Everest. Its area, covering 295,000 ㎢, surpasses the size of the Korean Peninsula (220,850 ㎢) and is nearly equivalent to that of France or Arizona. While Olympus Mons has a greater height than any mountain on Earth, its vast area results in an average slope of only 5 degrees. As a result, hikers who ascend Olympus Mons often feel as if they are traversing a flat plain. For humans, the steepness of a climb matters more than its height. For example, ascending a steeper 5 m pole can be more challenging than gradually scaling a 500 m mountain. In life, choosing the right slope to climb is often more crucial than focusing solely on the height reached, whether going uphill or downhill. - Joseph’s “just my thoughts”
