Scientists Pierre Agostini, Ferenc Krausz and Anne L'Huillier won the 2023 Nobel Prize in Physics for "experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter", the award-giving body said on Tuesday. 

The prize, which was raised this year to 11 million Swedish crowns (about $1 million), is awarded by the Royal Swedish Academy of Sciences. 

Physics is the second Nobel to be awarded this week after Hungarian scientist Katalin Kariko and US colleague Drew Weissman won the medicine prize for making mRNA molecule discoveries that paved the way for COVID-19 vaccines. 

Created in the will of dynamite inventor and businessman Alfred Nobel, the prizes for achievements in science, literature and peace have been awarded since 1901 with a few interruptions, becoming the arguably highest honor for scientists everywhere. 

While the sometimes controversial award for peace can hog the limelight, the physics prize has likewise often taken center stage with winners such as Albert Einstein and awards for science that has fundamentally changed how we see the world. 

Last year, Alain Aspect, John Clauser and Anton Zeilinger won the prize for work on quantum entanglement, where two particles are linked regardless of the space between them, something that unsettled Einstein himself who once referred to it as "spooky action at a distance". 

Announced on consecutive weekdays in early October, the physics prize announcement will be followed by ones for chemistry, literature, peace and economics, the latter a later addition to the original line-up.

The King Abdulaziz Public Library in Riyadh has revealed a rare collection of postage stamps that chronicle contemporary Saudi history.

The collection spans various national occasions and events, both before and after the founding of the Kingdom.

The library's stamp collection comprises 13,000 stamps, including rare specimens issued during the reign of King Abdulaziz Al Saud. The oldest stamp in the collection dates back to March 1925.

A particularly significant historical stamp commemorates King Abdulaziz's accession to the throne in 1931-1932, preceding the unification of the Kingdom on September 23, 1932. The first stamp bearing the name "Kingdom of Saudi Arabia" was issued in 1934, with several editions printed in various colors.

During King Abdulaziz's reign, stamp collections were issued to mark significant events such as the opening of the railway, visits by Arab and Islamic leaders, and the introduction of airmail services.

This valuable collection offers a fascinating glimpse into the historical development of Saudi Arabia and its postal system.
