1. War of conspiracy theory?

From China Daily:
Can the US open Fort Detrick, other labs for investigation?
2. Read some fascinating tutorial on Quantum Mechanics.

Does God play dice with the universe?

Causal determinism means the world is predictable if all the initial conditions are known. The world is like a giant clockwork governed by certain laws of nature. Some are known to human but most are not.

Heisenberg Uncertainty Principle says there's a fundamental limit to the precision with which the values for certain pairs of physical quantities of a particle, such as position, x, and momentum, p, can be predicted from initial conditions. The more precisely the position of some particle is determined, the less precisely its momentum can be predicted from initial conditions, and vice versa.

So maybe the law of cause and effect still hold, but one can never have all the information of initial conditions. It's not an observer effect but a fundamental property of quantum systems, where things are discrete not continuous, random not fixed.

It's good to know there's randomness in life and we're not destined by fate.
