SEMANTIC ANALYSIS

ⓘ The owner has associated the following topics to the website.

ⓘ The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by spie.org.

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Topics
Photonics Confidence: 79% Arrow up

Photonics is the physical science of light (photon) generation, detection, and manipulation through emission, transmission, modulation, signal processing, switching, amplification, and detection/sensing.

Though covering all light's technical applications over the whole spectrum, most photonic applications are in the range of visible and near-infrared light.

The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s and optical fibers developed in the 1970s.
SPIE Confidence: 78% Arrow up

SPIE is an American not-for-profit professional society for optics and photonics technology, founded in 1955.

It organizes technical conferences, trade exhibitions, and continuing education programs for researchers and developers in the light-based fields of physics, including: optics, photonics, and imaging engineering.

SPIE is most known for Photonics West, held in San Francisco.
Optics Confidence: 75% Arrow up

Optics is the branch of physics which involves the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it.

Optics usually describes the behaviour of visible, ultraviolet, and infrared light.

Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.
Engineering Confidence: 72% Arrow up

Engineering is the application of mathematics and scientific, economic, social, and practical knowledge in order to invent, innovate, design, build, maintain, research, and improve structures, machines, tools, systems, components, materials, processes, solutions, and organizations.
Scientific method Confidence: 70% Arrow up

The scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

To be termed scientific, a method of inquiry is commonly based on empirical or measurable evidence subject to specific principles of reasoning.

The Oxford Dictionaries Online define the scientific method as "a method or procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses".

Experiments need to be designed to test hypotheses.

The most important part of the scientific method is the experiment.
