Invention An invention is an object, patent, process,

or technique which displays an element of novelty. An invention may sometimes be based on earlier developments, collaborations or ideas, and the process of invention requires at least the awareness that an existing concept or method can be modified or transformed into a new invention. However, some inventions also represent a radical breakthrough in science or technology which extends the boundaries of human knowledge. Legal protection can sometimes be granted to an invention by way of a patent.

Alfred Bernhard Nobel Alfred Bernhard Nobel

(October 21, 1833, Stockholm, Sweden – December 10, 1896, Sanremo, Italy) was a Swedish chemist, engineer, innovator, armaments manufacturer and the inventor of dynamite...

Alfred Bernhard Nobel ... He owned Bofors, a

major armaments manufacturer, which he had redirected from its previous role as an iron and steel mill. In his last will, he used his enormous fortune to institute the Nobel Prizes. The synthetic element Nobelium was named after him.

DYNIAMITE Dynamite is an explosive

based on the explosive potential of nitroglycerin using diatomaceous earth (Kieselguhr) as an adsorbent. It is usually sold in the form of a stick roughly eight inches (20 cm) long and one inch (2.5 cm) in diameter but other sizes also exist. Dynamite is considered a "high explosive", which means it detonates rather than deflagrates.

History of dynamite Dynamite was the first safely manageable

explosive stronger than black powder. Nobel patented his discovery in October 1867. He originally sold dynamite as "Nobel's Blasting Powder". After its introduction, dynamite rapidly gained popularity as a safe alternative to gunpowder and nitroglycerin. Nobel tightly controlled the patent and unlicensed duplicators were quickly shut down. However, a few United States businessmen got around the patent by using a slightly different formula. Despite this, dynamite brought Nobel a great fortune, which he used to found the Nobel Prize.

How to make dynamite? Dynamite consists of three parts

nitroglycerin, one part diatomaceous earth and a small admixture of sodium carbonate. This mixture is formed into short sticks and wrapped in paper. Nitroglycerin by itself is a very strong explosive and in its pure form it is shock-sensitive (i.e., physical shock can cause it to explode), degrading over time to even more unstable forms. This makes it highly dangerous to transport or use in its pure form. Absorbed into diatomaceous earth, nitroglycerin is less shock-sensitive.

DYNAMITE- our friend... The chief uses of

dynamite used to be in construction, mining and demolition. However, newer explosives and techniques have replaced dynamite in many applications. Dynamite is still used, mainly as bottom charge or in underwater blasting.

DYNAMITE- our friend... Dynamite has been used

in armed conflicts, mainly to destroy bridges and other ways of travel, to slow the advance of supplies or enemy troops. Enthusiasts interested in safe-cracking have deliberately extracted nitroglycerin from dynamite by boiling the sticks and 'skimming' the nitroglycerin as it is forced out.

Nobel prize The Nobel Prizes are prizes awarded annually to people

(and, in the case of the Peace Prize, to organizations) who have completed outstanding research, invented ground-breaking techniques or equipment, or made an outstanding contribution to society in

physics, chemistry, literature, peace,

medicine or physiology and economics.

They are widely regarded as the

supreme commendation in their

respective subject areas. Those

honored with a Prize are known

as Nobel Laureates.Nobel Prize medal. Original design by the Nobel Foundation.
