Beginners understand that something happens.

If I put a seed in the ground and water it, a plant will grow.

If I flip the switch, the light turns on.

If I touch fire, my hand hurts.

Amateurs understand how it happens.

Germination occurs when you expose a healthy seed to water, good soil, and sunlight.

Flipping a switch allows electricity to flow to the light bulb, causing illumination.

A campfire burns at an average temperature of about 480°C.

Experts understand why it happens.

A specific combination of environmental factors, including proper exposure to water, oxygen, temperature, and light, trigger the cellular metabolism and growth of a seed.

When current flows through certain semiconductors, electrons recombine with electron holes, a process which releases energy in the form of photons.

My nervous system is equiped with nocieptors that detect potentially damaging thermal stimuli and cause a pain sensation when exposed to a minimum instensity of heat.
