Do you know, I used to be an aviation engineer.The computer will become an invention that will change the world!Back then, I thought of building an automatic machine that could help me deal with those cumbersome structure calculations.When that machine is completed, it will benefit all the scientists...Ah, how wonderful... why are you such a passionate man....No, it will be useful to everybody in the world.However, it shouldn't be limited to only aviation, but also construction and the military. A calculation machine that can stand in every field.
