Telescope (Part-Two); Types of Telescopes for Astronomy
Though Kepler telescope has faced a severe malfunction (on its four reaction wheels) during its designed mission and has almost loosed the stability, engineers didn’t just terminate the mission but devised a remarkable solution and used the pressure of sunlight to stabilize the spacecraft so it could continue to do science.
Telescope (Part-One); General Background
With many revisions and modifications, from the inventors and the scientific community, the commercial production of the telescope began in 1758 by John Dollond.
Do You Know, Today, June 14 is World Blood Donor Day?

Finding the Acceleration Due to Gravity, Radius of Gyration, and Moment of Inertia by using Compound Pendulum
Speed of Light - A Universal Constant, General Background
During the beginning of 17th century, almost all consider light as it does not have velocity. In the early period, many also assumed that the light …
Speed of Light; A Universal Constant but is Affected by Curvature of Space-Time
The concept of bending of light by gravity was introduced earlier by Newton. But later Einstein's theory predicts that the curvature of space caused by the Sun's mass should bend starlight twice as much as Newton's principles predict it should.

Whisky Tastes Better When Diluted with Water Before Drinking, Try it
No one till exactly knows why adding some water on whiskey glass made the test better. To solve this dilemma, researchers of chemistry at Linnaeus University, Sweden, Björn Karlsson, and Ran Friedman tried to study the chemical properties and behavior of water diluted whiskey using the computer simulation technique. The report was published in the journal Nature.
More Advanced Microscopy Technique - Cryogenic Electron Microscopy (cryoEM)
Traditional transmission electron microscopes (TEMs) are not effective for some materials particularly biomolecules and this advance Cryogenic Electron Microscopy (cryoEM) works properly.
