Reflecting Telescopes: All You Need to Know
Reflecting Telescopes: An Overview The history of telescopes is fascinating. The first telescope was invented in the 17th century. Note that it was spectacle-maker Hans Lippershey, who was credited as the inventor of the first refractor telescope, and Galileo Galilei, who pointed the telescope towards the skies. Early refractor telescopes, however, suffered from chromatic aberration, […]
Portable and Handheld Telescopes: All You Need to Know
Portable and Handheld Telescopes: Introduction Telescopes have undergone significant transformations since the 17th century – or when the first refractor telescope was invented. Note that spectacle-maker Hans Lippershey was credited as the inventor of the telescope and Galileo Galilei as the scientist who pointed the telescope towards the skies. In 1668 Sir Isaac Newton created […]
Magnifiers: All You Need to Know
I. Magnifiers: Introduction Magnifiers are defined as instruments that enlarge the size of images. Interestingly, the phenomenon of magnification was highly valued in the ancient world. In Ancient Egypt and Rome, for instance, people used crystals and gemstones to view small objects or images; the magnifying glass was also used to ignite paper. Note that […]

Catadioptric Telescopes: A Complete Guide
Catadioptric Telescopes: Introduction While both reflecting and refracting models continued improving over the years, advancements in lens technology outside the field of telescopy led to the development of the catadioptric telescope – a combination of refracting (lenses) and reflecting (mirrors) optics. To provide an example, in 1820, physicist Augustin-Jean Fresnel developed the prominent catadioptric lighthouse […]
Fluorescence Spectrophotometry: Principles and Applications
Fluorescence spectrophotometry is a set of techniques that deals with the measurement of fluorescence emitted by substances when exposed to ultraviolet, visible, or other electromagnetic radiation.Ā It has wide application in chemical and biological sciences as it can be used to analyze a biological system, by studying its interactions with fluorescent probe molecules (So and […]

There are different types of centrifuges that can be used for various applications, including research into organelles and biological molecules. Theory of Centrifugation The theory behind centrifugation […]
Radiation: Friend or Foe? What Can We Learn From Radiobiology?
We are routinely exposed to radiation. Simply, radiation is the propagation of energy in the form of waves or particles through material in space (Mu et al., 2018). The world is full of background radiation to which we are constantly exposed. Everything we see and hear comes to us in the form of radiation. Radiation […]
Colorimetry- a comprehensive guide for your color science
Ā Overview of Colorimetry Colorimetry, as the name suggests, means the measurement of colors. In terms of chemical analysis, it is, more specifically, the measurement of the concentration of a particular compound (solute) in a colored solution (solvent). During scientific work, we often need to measure quantities of a particular compound in a mixture or […]
