Terrorists also want to use simple and reliable arms.

Before attempting to create something new, it is vital to have a good appreciation of everything that already exists in this field.

I wanted to invent an engine that could run for ever. I could have developed a new train, had I stayed in the railway. It would have looked like the AK-47 though.

I'm proud of my invention, but I'm sad that it is used by terrorists.

My spiritual pain is unbearable. I keep having the same unsolved question: if my rifle claimed people's lives, then can it be that I a Christian and an Orthodox believer, was to blame for their deaths?

Things that are complex are not useful, Things that are useful are simple.

I had to gain experience as I did not have a technical education.
