The decision of whether or not to observe a light particle affects how the light behaves beforehand.

Composed of light-absorbing, colloidal quantum dots linked to carbon-based fullerene nanoparticles, these tiny two-particle systems can convert light to electricity in a precisely controlled way.

This shows that light is actually neither just a particle nor just a wave, but rather both simultaneously.

Light behaves like both a wave and a particle.

Nanophase can make them 50 nanometers wide, which renders the zinc oxide transparent no more white goop since each crystalline particle is small enough to allow harmless light to pass through.

Nanophase can make them as small as 50 nanometers wide, which renders the zinc oxide transparent no more white goop since each crystalline particle is small enough to allow harmless light to pass through.

And particles of sound, known as phonons, are just as susceptible to Heisenberg's uncertainty principle as particles of light (photons) or, indeed, any other fundamental particle.

Because nobody knows what the mass of a Higgs boson might be, the particle must be hunted indirectly, typically in giant machines that propel particles to near-light speed, then smash them together and generate an array of other subatomic particles.
