Widely considered by academics to be one of the most influential inventions of the past 1,000 years, the printing press set in motion both the democratisation of knowledge and the establishment of our modern, knowledge-based economies.

For the first time, valued texts could be produced in their thousands and – thanks to the co-evolution of nationwide and international trade routes – allowed texts to be accessed widely by the majority, not just the wealthy aristocracy and intellectual elite.

The man credited with the invention of the printing press is inventor Johannes Gutenberg, who lived and invented the press in Mainz, Germany. Here, around the year 1440 – an exact date is not known – Gutenberg designed a device based on screw presses that, when partnered with inked movable type heads, allowed paper to be quickly and efficiently pressed with letters.

The type heads were made by pouring a lead-tin alloy into a hand mould, and were then affixed to the top of movable, rectangular stalks. The stalks could then be arranged in order to create words and sentences within a rectangular container, before being fed under a screw press. The screw press then clamped a paper sheet on top of the type heads, pressing their ink onto the sheet.

While sounding crude by modern standards, in the 15th Century this was a groundbreaking invention. Before the Gutenberg press, texts were largely hand copied by monks and select few learned individuals. As such, the availability and cost of these texts was immense and they could only be accessed by a minuscule percentage of people.

Consequently, by the mid 16th Century and on to the Renaissance, printing presses had exploded all over Western Europe, producing millions of mass-produced texts on a diverse array of topics from politics to botany. Indeed, famous English philosopher Francis Bacon said that the emergence of typographical printing had “changed the whole face and state of things throughout the world.”

Designed in the aftermath of the evacuation of Dunkirk by the British Expeditionary Force, the Churchill tank was Britain’s attempt to readdress the technology gap between their ageing Matilda II battalion and the German Panzer tanks that had them out- gunned.

The result was the Mark I, a heavily armoured battle tank equipped with a two- pounder main gun, three-inch howitzer in the rear and the most advanced and robust suspension system yet conceived. It was a defensive juggernaut, designed with one goal: to dominate the European theatre of war.

From its introduction in June 1941, the tank proved a reliable and versatile weapon platform capable of engaging targets quickly and efficiently. Key to this was its high speed of 26km/h (16mph) and excellent turning ability, characteristics made possible by its multiple-bogie suspension system. The suspension was fitted to the hull under two large pannier enclosures on either side, with the tracks running over the top.

Initially, the Churchill was fitted with a two- pounder main gun and three-inch howitzer (artillery piece); however, the former was soon upgraded to a six-pounder cannon and the latter replaced with a high-calibre machine gun.

These cannons gave the Churchill decent stopping power against medium armour, yet still left them short in firepower when compared with their German contemporaries. The Churchill’s main cannon continued to be improved throughout its lifespan, with 75mm guns fitted to Mk IIIs.

Despite its average firepower, however, the Churchill’s high manoeuvrability and excellent armour made it one of the foremost tanks of WWII, being extensively deployed in Europe and North Africa.
