January 30: Martyrs Day

January 30 is celebrated as Martyrs Day to honour the brave martyrs of India who have sacrificed their lives for the country.

Why January 30 is celebrated as Martyrs Day?

January 30 marks the death anniversary of Mahatma Gandhi. On January 30, 1948, at the age of 78, Mahatma Gandhiji, Father of the Nation was assassinated by Nathuram Godse.

There were warnings about life threats to Gandhiji, Gandhiji refused to toe the government’s stand that he required security. Gandhiji threatened to leave Delhi if protection was thrust upon him. His associates cite that had he accepted security his assassination could have been averted.

How it is celebrated?

On the occasion of Martyrs Day, the President, the Vice President, the Prime Minister, the Defence Minister, and the three Service Chiefs gather at the Gandhiji’s samadhi at Raj Ghat memorial and lay wreaths. Bugles are blown sounding the Last Post. A two-minute silence in memory of Indian martyrs is observed across the country at 11 AM and participants hold all-religion prayers and sing tributes in the honour of Martyrs.

International Year of the Period Table of Chemical Elements

UNESCO has declared 2019 as the International Year of the Period Table of Chemical Elements to commemorate the 150th birthday of the periodic table of chemical elements. The Periodic table of the Chemical elements was first published by Russian scientist Dmitry Mendeleev in the year 1869.

What is this Periodic Table of Chemical Elements?

The Periodic Table of Chemical Elements is the tabular arrangement of the chemical elements, arranged by atomic number, electron configuration, and recurring chemical properties. The important features of the periodic table are:

  • The seven rows of the table are called as periods and generally accommodate metals on the left and non-metals on the right.
  • The columns of the table are called groups and contain elements with similar chemical behaviours.
  • The elements from atomic numbers 1 (hydrogen) to 118 (oganesson) have been discovered in nature or synthesized in laboratories.
  • The first 98 elements listed in the periodic table occur naturally, though some are found only in trace amounts and a few were discovered in nature only after having first been synthesized.
  • Elements from 99 to 118 have only been synthesized in laboratories or nuclear reactors.
  • Efforts are on to elements having higher atomic numbers these elements would begin the eighth row, and theoretical work has been done to suggest possible candidates for this extension.

To celebrate the International Year of the Period Table of Chemical Elements the UNESCO would be organising events like online competition to test high school students’ knowledge of the table, and scientific experiments brought to schools around the world.
