The Galileo Thermoscope In 1603 there was an invention that changed how our society works. Thermometers gave us a sophisticated understanding of heat. Thermometers are used almost everywhere, doctors use them, people in the weather industry use them, it is so efficient it is even used by your parents to immediately check if you have a fever. They are more efficient and reliable than measuring temperature with a hand or using your feelings to tell the weather. But how did this amazing invention come to be? In 1603 the renowned scientist Galileo Galilei invented a thermoscope. The thermoscope he invented worked on the principles of buoyancy and gravity. The Galileo thermoscope had water with hand blown glass bulbs, filled with a coloured liquid for…show more content…
The thermoscope did not have a scale at all. Under the hand blown bulbs there were metal tags attached, with each of the metal tags somewhat differing in weight. As the temperature increased the water’s temperature increased too causing the bulbs close to the original temperature to rise to the top and the bulb with the exact temperature to sink down slightly below the bulbs which are close to the surrounding temperature. Although the thermoscope was partly credited to have been being created by Galileo the original inventor was Santorio Santorio. Santorio was a close friend of Galileo who had received the blueprints from Galileo himself. In order to make Galileo’s thermoscope into a thermometer Santorio added a scale so that the precise temperature would be indicated by the bulb slightly below the bulbs on top. In conclusion, I believe that the first thermometer has impacted society by helping it become more efficient and useful also the Galileo thermometer would make a whole new world for new
It is often stated that the great Italian scientist Galileo Galilei ""invented"" the thermometer that now bears his name. … According to the biographer Viviani, writing in 1718, Galileo invented a thermometer around the time he was made chair of mathematics at Padua university in late 1592.
Who invented the thermometer first?
1612: Santorio Santorio – the first thermometer The Italian, Santorio Santorio (1561-1636) is generally credited with having applied a scale to an air thermoscope at least as early as 1612 and thus is thought to be the inventor of the thermometer as a temperature measuring device.
Who actually invented the Galileo thermometer?
The credit for developing the “Galilean thermometer” must go to the Accademia del Cimento, a research organization active in Florence from 1657 to 1667 under the leadership of Ferdinand II, Grand Duke of Tuscany.
Did Galileo invent a mercury thermometer?
The great Italian scientist Galileo may have been the first person to use a telescope to observe the heavens, helping spark the scientific revolution of the 16th century, but Galileo definitely did not invent the famous thermometer and captivating curiosity that bears his name, according to a new article.
What did Galileo invent to measure temperature?
thermoscope While working in Padua in 1596, Galileo invented a device called the 'thermoscope.
Who invented digital thermometer?
Galileo Galilei is the person who invented digital thermometer. He was also a mathematician, engineer, physicist, astronomer. He also played a major role in scientific revolution of the 17th century.
Who invented Celsius thermometer?

Did Galileo invent the first telescope?
Galileo Galilei (1564-1642) was part of a small group of astronomers who turned telescopes towards the heavens. After hearing about the "Danish perspective glass" in 1609, Galileo constructed his own telescope. … The initial telescope he created (and the Dutch ones it was based on) magnified objects three diameters.
Thermometers measure temperature by using materials that change in some way when they are heated or cooled. In a mercury or alcohol thermometer, the liquid expands as it is heated and contracts when it is cooled, so the length of the liquid column is longer or shorter depending on the temperature. Modern thermometers are calibrated in standard temperature units such as Fahrenheit (used in the United States) or Celsius (used in Canada), or Kelvin (used mostly by scientists).

Before there was the thermometer, there was the earlier and closely related thermoscope, best described as a thermometer without a scale. A thermoscope only showed the differences in temperatures; for example, it could show something was getting hotter. However, the thermoscope did not measure all the data that a thermometer could, such as an exact temperature in degrees.
Galileo Galilei (1564-1642), wood engraving, published in 1864.Several people invented a version of the thermoscope at the same time. In 1593, Galileo Galilei invented a rudimentary water thermoscope, which for the first time allowed temperature variations to be measured. Today, Galileo's invention is called the Galileo Thermometer, even though by definition it was really a thermoscope. It was a container filled with bulbs of varying mass, each with a temperature marking. The buoyancy of water changes with temperature. Some of the bulbs sink while others float, and the lowest bulb indicated what temperature it was.
In 1612, the Italian inventor Santorio Santorio became the first inventor to put a numerical scale on his thermoscope. It was perhaps the first crude clinical thermometer, as it was designed to be placed in a patient's mouth for temperature taking.
Neither Galileo's nor Santorio's instruments were very accurate.
In 1654, the first enclosed liquid-in-a-glass thermometer was invented by the Grand Duke of Tuscany, Ferdinand II. The Duke used alcohol as his liquid. However, it was still inaccurate and did not use a standardized scale.
An old style mercury thermometer, which isn't safe if it breaks, and could be hard to read anyway.What can be considered the first modern thermometer, the mercury thermometer with a standardized scale, was invented by Daniel Gabriel Fahrenheit in 1714.
Daniel Gabriel Fahrenheit was the German physicist who invented the alcohol thermometer in 1709 and the mercury thermometer in 1714. In 1724, he introduced the standard temperature scale that bears his name—Fahrenheit scale—that was used to record changes in temperature in an accurate fashion.
The Fahrenheit scale divided the freezing and boiling points of water into 180 degrees; 32 degrees was the freezing point of water and 212 degrees was its boiling point. Zero degrees was based on the temperature of an equal mixture of water, ice, and salt. Fahrenheit based his temperature scale on the temperature of the human body. Originally, the human body temperature was 100 degrees on the Fahrenheit scale, but it has since been adjusted to 98.6 degrees.
The Celsius temperature scale is also referred to as the "centigrade" scale. Centigrade means "consisting of or divided into 100 degrees." In 1742, the Celsius scale was invented by Swedish Astronomer Anders Celsius. The Celsius scale has 100 degrees between the freezing point (0 degrees) and boiling point (100 degrees) of pure water at sea level air pressure. The term "Celsius" was adopted in 1948 by an international conference on weights and measures.

Lord Kelvin took the whole process one step further with his invention of the Kelvin Scale in 1848. The Kelvin Scale measures the ultimate extremes of hot and cold. Kelvin developed the idea of absolute temperature—called the "Second Law of Thermodynamics—and developed the dynamical theory of heat.
In the 19th century, scientists were researching what the lowest temperature possible was. The Kelvin scale uses the same units as the Celsius scale, but it starts at Absolute Zero, the temperature at which everything, including air, freezes solid. Absolute zero is 0 degrees Kelvin, which is equal to minus 273 degrees Celsius.
When a thermometer was used to measure the temperature of a liquid or of air, the thermometer was kept in the liquid or air while a temperature reading was being taken. Obviously, when you take the temperature of the human body you can't do the same thing. The mercury thermometer was adapted so it could be taken out of the body to read the temperature. The clinical or medical thermometer was modified with a sharp bend in its tube that was narrower than the rest of the tube. This narrow bend kept the temperature reading in place after you removed the thermometer from the patient by creating a break in the mercury column. That is why you shake a mercury medical thermometer before and after you use it to reconnect the mercury and get the thermometer to return to room temperature.

In 1612, the Italian inventor Santorio Santorio invented the mouth thermometer and perhaps the first crude clinical thermometer. However, it was both bulky, inaccurate, and took too long to get a reading.
The first doctors to routinely take the temperature of their patients were Hermann Boerhaave (1668–1738); Gerard L.B. Van Swieten (1700–1772), founder of the Viennese School of Medicine; and Anton De Haen (1704–1776). These doctors found temperature correlated to the progress of an illness. However, few of their contemporaries agreed, and the thermometer was not widely used.
Modern digital thermometers all descend from the first medical thermometer invented by Sir Thomas Allbutt.English physician Sir Thomas Allbutt (1836–1925) invented the first practical medical thermometer used for taking the temperature of a person in 1867. It was portable, 6 inches in length, and able to record a patient's temperature in 5 minutes.
