Scientific Curiosity Captured in Photos Caleb Charland is a Maine-based photographer who combines a love of scientific experiments and photographs into wonderful and amazing photographs. If Isaac Newton or Benjamin Franklin were into photography, their photographs might look something like these: “Wooden Box with Horseshoe Magnet” “Atomic Model” “Demonstration with Hair Dryer and Aluminum Foil” Timelines This British Library timeline allows you to explore collection items chronologically, from medieval times to the present day. It includes a diverse combination of texts: those that allow glimpses of everyday life (handbills, posters, letters, diaries), remnants of political events (charters, speeches, campaign leaflets), and the writings of some of our best known historical and literary figures.

Slicers, Scimitars and Choppers Ok, I'll admit it. Lumping Scimitars and Falchions (and Messers) in with Sabers together in one category like this is a bit of a stretch... After all they come from very different time periods, were used in very different periods (two were cavalry swords, eastern and western, the others an oversized butchers knife of a peasant conscript) - but the medieval Falchion, Middle Eastern Scimitar and the early modern Saber all have one thing in common. They are exceptionally good at slicing and chopping things into pieces! In this article, we will be taking a brief look at all of these blades - from the battlefield huge cleaver knife of the conscripted peasantry - used with about the same grace as one would use an axe (and with a similar effect) to the noble swords of cavalries, both Eastern and Western that would ride in on horseback and 'cleave a man in twain' to put it quaintly.
The Mysterious Plain of Jars Often referred to as “an Asian version of Stonehengeâ€, the Plain of Jars is one of the most enigmatic sights on Earth. Shrouded in mystery and myth, this ancient place has fascinated archeologists and scientists ever since its discovery. [Photo Credits] Thousands of giant stone jars scattered around the Xieng Khouang plain, in Laos form one of the most bizarre archeological collections in history. Although it has been determined they are over 2000 years old, no one has yet been able to determine who built them and for what purpose. Made of sedimentary rock, like sandstone or granite, and calcified coral, the jars weigh up to 13 tons and are between 1 and 3 meters high. [Photo Credits]
Albert Einstein at the IISH Seventy-five years of systematic collection by the IISH does not only mean bringing together all kinds of collections from individuals and institutions who are important to social history, but also leads to a 'condensing' of documents from people whose own archives have not ended up at the Institute. Albert Einstein's (1879-1955) letters offer a good example of this process. On the occasion of the new president of the Royal Netherlands Academy of Arts and Sciences (KNAW) Robbert Dijkgraaf's introductory visit to the IISH (7 July 2008), we explored the possibility of exhibiting several of Einstein's letters. After all, Dijkgraaf is a renowned physicist and Einstein was once a foreign member of the KNAW. To our own surprise, a rummage through various archives did not only yield dozens of letters and manifests, but also a lecture with discussion, an unpublished preface, and various visual artefacts.
