Light Acquisition02:16

Light Acquisition

9.4K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Light as Energy01:35

Light as Energy

95.6K
The energy required to carry out photosynthesis is light— typically electromagnetic radiation from the sun. The range of all possible wavelengths is known as the electromagnetic spectrum.
Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...

The Wave Nature of Light02:12

The Wave Nature of Light

61.0K
The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

Photoreceptors and Plant Responses to Light02:00

Photoreceptors and Plant Responses to Light

28.3K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

5.5K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Atomic Absorption Spectroscopy: Radiation and Light Sources01:13

Atomic Absorption Spectroscopy: Radiation and Light Sources

1.2K
Atomic absorption spectroscopy (AAS) relies on the Beer-Lambert law, which requires that the radiation source emits a narrow range of wavelengths to match the absorption characteristics of the analyte atom. The primary criteria for choosing an appropriate radiation source in AAS is to provide a precise and intense emission at specific wavelengths that will allow accurate detection of the analyte.
Two common narrow-range 'line' sources used in AAS are hollow-cathode lamps (HCLs) and...

Area of Science:

  • History of Science
  • Medical History
  • 19th-Century Scientific Networks

Background:

  • John Davy, brother of Sir Humphry Davy, served as an army doctor and researcher.
  • His early career and intellectual development are less documented than his brother's.

Purpose of the Study:

  • To examine the crucial formative period (1808-1814) of John Davy's life.
  • To situate John Davy within the scientific and literary cultures and networks of his time.
  • To explore his early research and disputes.

Main Methods:

  • Analysis of three previously unpublished manuscript sources from the Davy Letters Project.
  • Examination of John Davy's activities at the Royal Institution, as a student in Edinburgh, and in Cornwall.
  • Investigation of his scientific dispute with John Murray.

Main Results:

  • Details John Davy's work as an assistant at the Royal Institution (1808-1811).
  • Documents his student period in Edinburgh (1811-1813) and a scientific dispute over muriatic acid gas.
  • Covers his return to Cornwall in 1814 before his military medical postings.

Conclusions:

  • The study illuminates a key period in John Davy's development as a scientist and physician.
  • It highlights his engagement in contemporary scientific discourse and networks.
  • Provides context for his later career as an army doctor and editor of his brother's works.
