Why are there questions that no computer can answer?
Some problems are undecidable: no computer can solve them, no matter how powerful.
Charles Petzold · The Annotated Turing
How does a rational agent function in artificial intelligence?
Artificial intelligence is built through rational agents that perceive their environment and act to achieve goals.
Stuart Russell și Peter Norvig · Artificial Intelligence: A Modern Approach
What happens if only passwords are protected while people and processes remain vulnerable?
Digital security relies on the entire ecosystem, not just passwords and encryption.
Bruce Schneier · Secrets and Lies: Digital Security in a Networked World
What nullifies the protection of a strong cryptographic algorithm?
Modern cryptography protects messages only if the mathematical algorithms are implemented without errors.
Bruce Schneier · Applied Cryptography: Protocols, Algorithms, and Source Code in C
Why are social engineering attacks so effective?
The most vulnerable element of security is human psychology, not the firewall.
Kevin D. Mitnick · The Art of Deception: Controlling the Human Element of Security
Why is information security a continuous race?
Every new encryption method is eventually broken by creative people.
Simon Singh · The Code Book: The Science of Secrecy from Ancient Egypt to Quantum Cryptography
What guarantees that a simple Turing machine is so powerful?
A simple Turing machine can compute anything any other computer ever could.
Alan Turing · On Computable Numbers, with an Application to the Entscheidungsproblem
What fundamental unit of information measurement did Shannon introduce?
Any information can be reduced to a sequence of simple yes/no questions, called bits.
Claude Shannon · A Mathematical Theory of Communication
Why do people and computers aim for a good‑enough solution instead of the optimal one?
People and computers settle for “good enough” solutions because of bounded rationality
Herbert A. Simon · The Sciences of the Artificial
What happens to a simple program’s performance when the data volume grows significantly?
A good program doesn’t just work; it uses the most efficient method, like a chef choosing the optimal recipe
Donald Knuth · The Art of Computer Programming
What happens when a system refers to itself?
Consciousness arises from self‑referential loops, like a hand drawing itself.
Douglas Hofstadter · Gödel, Escher, Bach: An Eternal Golden Braid
How does an automatic system adjust itself to reach a desired state?
Systems self-regulate by using feedback from the results of their own actions.
