Metropolis and Transportation: For mankind, a ‘city’ was a ‘place’ where people were born, grew up, and eventually died. It was initially difficult for humans to choose a ‘place’ to live. Humans had to follow the fate they were given. However, with the development of transportation and the widespread adoption of online networks, humans have been able to select their own places of residence. Throughout history, humans have only been able to voluntarily choose where they want to live for a short time. Achieving freedom of movement marks a fundamental change in the form and character of cities. The development of transportation has completely transformed our lives. The emergence and evolution of transportation means, such as electric vehicles and high-speed trains, indicate that we are in the middle of a revolution that humanity is experiencing for the first time. If you do not respond to these changes, you will face difficulties. - Joseph’s “just my thoughts”
Human blood is a liquid that maintains a pH between 7.3 and 7.4. A change of just 0.2 in pH can be fatal. The substance responsible for regulating blood pH is carbonic acid. When carbonic acid dissolves in the blood, it creates a cooling sensation, contributing to the appeal of drinking soda. Humans convert food into glucose through digestion for energy, and this glucose combines with oxygen in a process called breathing to generate carbon dioxide, water, and ATP, which are essential for energy production. A significant amount of carbon dioxide is produced in this process. To meet a daily energy requirement of 2,560 calories, one needs to burn 640 grams of glucose with oxygen, resulting in the production of 938 grams or 552 liters of carbon dioxide. When carbon dioxide dissolves in water, it forms carbonic acid, which circulates in the bloodstream and exits the body through the lungs. While some argue that soda is unhealthy, especially for individuals with specific conditions, it is es...
