Trivial facts which you did not know,
Invention of the ESCALATOR
1900 Escalator invented by Charles Seeberger
Escalator = Scala Elevator
The escalator as we know it was later re-designed by Charles Seeberger in 1897, who created the name 'escalator' from the word 'scala', which is Latin for steps and the word 'elevator', which had already been invented.
An escalator is a conveyor type transport device that moves people. It is a moving staircase with steps that move up or down using a conveyor belt and tracks keeping each step horizontal for the passenger. However, the escalator began as an amusement and not as a practical transport. The first patent relating to an escalator-like machine was granted in 1859 to a Massachusetts man for a steam driven unit. OnMarch 15 1892, Jesse Reno patented his moving stairs or inclined elevator as he called it. In 1895, Jesse Reno created a new novelty ride at Coney Island from his patented design, a moving stairway that elevated passengers on a conveyor belt at a 25 degree angle.
The escalator as we know it was later re-designed by Charles Seeberger in 1897, who created the name 'escalator' from the word 'scala', which is Latin for steps and the word 'elevator', which had already been invented.
Charles Seeberger, together with the Otis Elevator Company produced the first commercial escalator in 1899 at the Otis factory in Yonkers, N.Y. The Seeberger-Otis wooden escalator won first prize at the Paris 1900 Exposition Universelle in France. Jesse Reno's Coney Island ride success briefly made Jesse Reno into "the" escalator designer and he founded the Reno Electric Stairways and Conveyors company in 1902.
Charles Seeberger sold his patent rights for the escalator to the Otis Elevator Company in 1910, who also bought Jesse Reno's escalator patent in 1911. Otis then came to dominate escalator production, and combined and improved the various designs of escalators.
According to Otis, "In the 1920s, Otis engineers, led by David Lindquist, combined and improved the Jesse Reno and Charles Seeberger escalator designs, and created the cleated, level steps of the modern escalator in use today. Over the years, Otis dominated the escalator business, but lost the product's trademark. The word escalator lost its proprietary status and its capital "e" in 1950 when the U.S. Patent Office ruled that the word "escalator" had become just a common descriptive term for moving stairways."

One hour before Alexander Graham Bell registered his patent for the telephone in 1876, Elisha Gray patented his design. After years of litigation, the patent went to Bell.
Thomas Edison filed 1,093 patents, including those for the light bulb, electric railways and the movie camera. When he died in 1931, he held 34 patents for the telephone, 141 for batteries, 150 for the telegraph and 389 patents for electric light and power.
The first fax process was patented in 1843.
Count Alessandro Volta invented the first battery in the 18th century.
During the 1860s, George Leclanche developed the dry-cell battery, the basis for modern batteries.
In 1894 Thomas Edison and W K L Dickson introduced the first film camera.
In 1895 French brothers Auguste and Louis Lumiere demonstrated a projector system in Paris. In 1907 they screened the first public movie.
The first electronic mail, or “email”, was sent in 1972 by Ray Tomlinson. It was also his idea to use the @ sign to separate the name of the user from the name of the computer.
Queen Elizabeth of Britain sent her first email in 1976.

1998..Nobel Prize for medicine and Physiology.
Robert F. Furchgott
Louis J. Ignarro
Ferid Murad
The Nobel Prize in Physiology or Medicine 1998 was awarded jointly to Robert F. Furchgott, Louis J. Ignarro and Ferid Murad "for their discoveries concerning nitric oxide as a signalling molecule in the cardiovascular system".
Importance in medicine today and tomorrow
Heart: In atherosclerosis, the endothelium has a reduced capacity to produce NO. However, NO can be furnished by treatment with nitroglycerin. Large efforts in drug discovery are currently aimed at generating more powerful and selective cardiac drugs based on the new knowledge of NO as a signal molecule.

Shock: Bacterial infections can lead to sepsis and circulatory shock. In this situation, NO plays a harmful role. White blood cells react to bacterial products by releasing enormous amounts of NO that dilate the blood vessels. The blood pressure drops and the patient may become unconscious. In this situation, inhibitors of NO synthesis may be useful in intensive care treatment.
Lungs: Intensive care patients can be treated by inhalation of NO gas. This has provided good results and even saved lives. For instance, NO gas has been used to reduce dangerously high blood pressure in the lungs of infants. But the dosage is critical since the gas can be toxic at high concentrations.
Cancer: White blood cells use NO not only to kill infectious agents such as bacteria, fungi and parasites, but also to defend the host against tumours. Scientists are currently testing whether NO can be used to stop the growth of tumours since this gas can induce programmed cell death, apoptosis.
Impotence: NO can initiate erection of the penis by dilating the blood vessels to the erectile bodies. This knowledge has already led to the development of new drugs against impotence.
Diagnostic analyses: Inflammatory diseases can be revealed by analysing the production of NO from e.g. lungs and intestines. This is used for diagnosing asthma, colitis, and other diseases.
NO is important for the olfactory sense and our capacity to recognise different scents. It may even be important for our memory.

Spectacles.
Modern glasses are typically supported by pads on the bridge of the nose and by temple arms (sides) placed over the ears. CR-39 lenses are the most common plastic lenses due to their low weight, high scratch resistance, low dispersion, and low transparency to ultraviolet and infrared radiation.[citation needed] Polycarbonate and Trivex lenses are the lightest and most shatter-resistant, making them the best for impact protection.[1]
An unpopular aspect of glasses is their inconvenience. Though modern frames can be both lightweight and flexible, and new lens materials and optical coatings are resistant to breakage or scratching, glasses can still cause problems during rigorous sports. Visibility can be significantly reduced by becoming greasy, trapping vapour when eating hot food, swimming, walking in rain or rapid temperature changes (such as walking into a warm building from cold temperatures outside). Scraping, fracturing, or breakage of the lenses require time-consuming and costly professional repair.
