What happens when you take the factorial of one half?

You can't multiply ½ × ... × 1. That makes no sense.

But mathematicians found a way — the Gamma function.

Here's the deep explanation:
• Why factorial counts arrangements
• How Gamma extends it to ALL numbers
• The Gaussian integral trick (squaring!)
• Why (½)! = Γ(3/2), not Γ(½)
• The beautiful result: √π/2 ≈ 0.8862

Most videos just state the answer. We explain WHY it works.
