 TORRICELLI INVENTS THE BAROMETER

THE LAST WEEK EVANGELISTA TORRICELLI SHOWED THAT THE AIR HAS WEIGHT

 

This physicist and mathematician at the University of Pisa and born on October 15, 1608 in Faenza discovered after a long work the BAROMETER.

To do this, he used the mercury by ascending it in a tube, creating a vacuum in the upper part, pushed by the weight of the air in the atmosphere. So he showed that the air has weight. 

The barometer is used to measure atmospheric pressure or barometric pressure, that is, to measure the pressure in an open vessel and also to calculate the height of the mountains.

Torricelli's theorem is an application of Bernoulli's principle and studies the flow of a liquid contained in a container, through a small hole, under the action of gravity.

Over time we will discover if this Galileo Galiley student, a student educated at Benedetto Castelli and now a PhD supervisor, makes this invention one of the most important of the time.

THE BATTLE OF THE LAND: PHYSIOCRATS AND LOUIS XV

10/20/1758 (Paris)

With a war against Great Britain still on, Louis XV has to face a new economic movement: the physiocracy

The current king, Louis XV, The Beloved, was for a time loved by the

Louis XV

people as a courageous and capable king. However, for some time 
he has gotten into battles for land he has not been able to win, and 
the current one against Great Britain and Prussia does not seem to
be different. All this added to the scandals concerning their 
followers have made the town have a bad image of Louis XV, 
see in the stab he received about a year ago for one of his servants, 
a wound from which the king recovered. But now our king faces 
another problem: physiocracy. Recently a book has been published 
by François Quesnay, the king's doctor since 1744, and his name is 
"Tableau Économique". This text defends that wealth is based on
food produced by the country, mainly agriculture, disregarding trade
and manufacturing as sources of wealth, considering them "sterile”.
This is based in Britain’s system, where the land and weather make
agriculture easier. The supporters of this movement, the physiocrats,

François Quesnay

try that neither the owner of the land nor the state intervene in these
activities and that the price of the land is lowered, ideas that Quesnay
coined under the term
"Laissez-faire", something that to the King does not seem like a good
idea even though the movement is gaining strength and more and more
followers.

Here you have a resumed video that we recorded about Louis XV (you
need to turn captions in english)

And Here you´ve got an Spanish adaption of the "Tableau Economique"

THE NEW VACCINE THAT IS SAVING 

SO MANY LIFES   

Finally the cure to the deadliest disease of the time 
is discovered: the smallpox.

As you know, lately the smallpox virus has spread very quickly. This is a contagious disease caused by a virus which is characterized by causing fever and the appearence of pus. It can be transmitted through direct contact with infected body fluids or with contaminated objects, such as sheets, covers or clothing.

The English physician and scientist Edward Jenner has discovered last Wednesday the cure for the disease that more deaths is currently causing. He has achieved it by extracting pus from a pustule from the hand of Sarah Nelmes, a milker who had contracted her cow's smallpox, and inoculating it into a healthy 8-year-old boy named James Phipps, who later incubated the disease between the 7th and the 9th day. Eventually, he inoculated him with the smallpox virus, but he didn't get sick since a vesicle had formed at the inoculation points and thanks to that, he knew that he had discovered the cure for smallpox.

On our part, we want to thank Edward Jenner for his great discovery and we hope that many more lifes will be saved.
