The year is 1915. It's the beginning of November. You are a college student and near your house lives a mad scientist. People don't like him. But, he is your friend and you occasionally visit him. You get to learn about different science stuff.
One day, he calls you and says he has something to show you. He asked you to come to his house at midnight.
At midnight, he took you to a nearby field. He gave you a cylindrical container and asked you to set its tail on fire. Once you lit it, it began expelling a huge amount of gas vertically to the ground. It then rose up, and zipped high up to the sky. It never came back down again.
Dr. Scientist explains that it would reach an altitude of 20,000 kilometers and then orbit the earth once in roughly 12 hours time. Previously, he has sent 23 such containers to orbit the earth in a network. He then pulls out an instrument from his bag. He pressed the button saying "PRINT". The instrument prints out on a sheet of paper some coordinates. Dr. Scientist says that those were the coordinates of his favorite pen. No matter where you keep the pen on earth, the instrument would print out its location. He then went on to tell some of the complexities he is facing in designing the final model of the instrument. Some you understood, some you didn't.
Two days later, you go to his house again. But, wait! Something feels strange. You rush to the doctors lab and find the whole place in a mess. The doctor has been robbed? You search for the doctor. Is the doctor safe? Where is he? You then find a note on under the table.
It says,
Beta,You go back to your room and there you find the instrument. This is where the actual question begins.
You press "PRINT". The printed page shows the coordinates.
