THE TIME MACHINE

Many people dream of traveling to the past or the future, but that is physically impossible. That is why our mind is our personal time machine. We relive the past through our memories, process the present with our senses, and build the future using our imagination and anticipation. The mind is the subjective entity that allows us to gain knowledge and experience ideas, feelings, and memories. The mind is not bound by space or time. We reconstruct the past through history, and we imagine the future through science fiction. A song we enjoyed in the past can evoke emotional memories; this is known as nostalgia. History is the social science that studies the past by examining the evidence left behind by each era. Physically, it is impossible to travel through time—to the past or the future. We are prisoners of time. We are born, we live, and we die. I would like to share a list of ten artists I have listened to since my youth. I am now 62 years old. 

1- Salvatore Adamo 2- Leonardo Favio 3- Manolo Galván 4- Leo Dan 5- Nino Bravo 6- Los Angeles Negros 7- Charles Aznavour 8- Ruddy Marqués 9- Joe Dassin 10- Danny Daniel

TIME: MEASURE OF THE PAST

Ever since the Earth began its motion, it has served as a measure of the passage of time. The day is measured by the planet's rotation, and the year by its revolution. Currently, years are calculated from the birth of Christ—2,026 years have passed since then. The age of the universe is calculated from the Big Bang: 13.8 billion years. Days are measured in hours, spanning from one midnight to the next. A person's age begins at birth. Clocks measure time based on midnight and noon. As the examples above show, the measurement of time always involves the past. Although the past no longer exists, the sequential measurement of time remains. Time is a sequential mathematical entity. The fact that the past does not exist leads some to believe that time itself does not exist, it's an illusion.
