The Periodic Table of AI

The AI deciding: is this right or wrong?

• "Is 2 + 2 = 5?" → No.
• "Is water wet?" → Yes.
• "Should I trust this email?" → Yes or No.

Every fact check, every safety filter — all Boolean.

Anything involving amounts, sizes, or comparisons.

• "How many planets?" → 8.
• "What's bigger — elephant or car?" → Elephant.
• "How much does water weigh?" → 8.34 lbs/gallon.

If the answer is a number, a size, or a rank — it lives here.

The language pieces themselves — not what words mean, but what they ARE.

• "What does 'photosynthesis' mean?"
• "Is this Python code correct?"
• "What does '∞' represent?"

Spelling, grammar, code syntax, abbreviations — all Symbol.

Names of real things in the world: people, places, organizations.

• "Who is Einstein?" → A physicist.
• "Where is Tokyo?" → Japan.
• "Who made the iPhone?" → Apple.

Where things are relative to each other. Inside, outside, above, below, near, far.

• "Is the heart on the left or right?"
• "Which direction does the sun rise?"
• "Is Antarctica bigger than Europe?"

Physical position, geography, spatial relationships — Space.

Everything about timing, sequence, and dates.

• "When did World War II end?" → 1945.
• "How long does light take from the Sun?" → 8 minutes.
• "What came first — Renaissance or Industrial Revolution?"

Dates, durations, order of events — all Time.

How things connect to each other. Because, therefore, part of, similar to, opposite of.

• "Why does ice melt in warm weather?"
• "What's the connection between smoking and cancer?"
• "What is France part of?" → Europe → Earth.

The hardest type for AI. Requires understanding WHY, not just WHAT.

How confident is the AI? Is it guessing? Is the answer definite or just "probably"?

• "Will it rain tomorrow?" — maybe.
• "What's the most common surname in China?" — probably Wang.
• "Is this symptom serious?" — possibly, see a doctor.

When the answer is "it depends" or "probably" — that's Entropy.
