Kirk Deitschman Hist Professor Bindi 26 April 2016 History of the Thermometer Temperature is the numerical representation of hot and cold usually measured by a thermometer. Temperature is also the measurement of how fast molecules and atoms of substances are moving. Temperature is measured in degrees on three different scales, Fahrenheit, Celsius or Kelvin. The thermometers we know today was not developed or invented by one specific person but was a collaborative effort from numerous different
medical devices ranging from clinical equipment to micro-implants, common imaging equipment such as MRIs and EEGs, biotechnologies such as regenerative tissue growth, pharmaceutical drugs and biopharmaceuticals. Biomedical engineering can trace its history to as far back as a hundred years ago when the first X-ray machines and electrocardiographs dramatically illustrated how technology could be used for the diagnosis of disease. Today the field of biomedical engineering is in full power, propelled by
Thermometers 1) Mercury thermometer History: The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam (1714). How does it work? The main element of a mercury thermometer is a capillary tube. The tube is sealed on both sides of the nutria and she pumped the air. At one end of the tube is a reservoir of mercury. To measure the temperature there is a special scale. Scale deposited on the bar attached to the tube. Scale measurement range from 34 to 42
snowfall, and record low temperatures. Monitoring temperatures is part of our everyday life — whether we're talking about the weather, our bodies, central heating, or cooking. In the United States, we typically measure temperature in degrees Fahrenheit. But in other countries, such as England, you'll get the weather forecast in degrees Celsius. Recipes will advise you to bake a pie at 205ºC and not 400ºF. In fact, the Celsius scale is the most commonly used temperature scale in the world. This week
scientific field, it made him to be acknowledged as one of many influential British inventors and scientists. He invented around fifty devices, wrote hundreds of scientific papers, and was the one that defined “absolute zero” in the Kelvin temperature scale. At the age of 10, Thomson attended Glasgow University. Even though it might seem as a very young age to attend a University, at that time in Scotland, schools were competing among each other. Accepting young, smart students was a positive impact
global temperature can be assessed by making the appropriate measurements and analyzing the data in a way that shows the connections and their magnitudes. Human population can be closely estimated and the consequences of their activities can be measured. For example, the volume of carbon dioxide, methane and nitrous oxide emissions is an indicator of human's energy and resource consumption. An examination of population size, atmospheric concentrations of these gases and global temperature relative
ash contains particulates and sulfuric aerosols which reduce the amount of light received from the sun (Burke, 1985). These smaller scale eruptions cause a net cooling effect due to the volume of ejecta and the light dispersing properties of the particulates released after an eruption. There is also evidence of volcanoes causing a global warming effect in Earth’s history. This was true during the Cretaceous time period where CO2 production dwarfed the CO2 levels of today (Refer to Figure 4). Large quantities
brackish-water marshes with salinities up to 14 ppt in southern France and on capturing common carp in waters with salinities as high as 17.6 ppt. in USA. Even the best growth of common carp is obtained when water temperature ranges between 23 °C and 30 °C, fish can withstand higher water temperatures and can survive cold winter periods.
industrial products. Epoxies demonstrate time and temperature dependent of mechanical properties specifically the creep compliance. As the constant load is being applied on the system, the material starts slow deformation. At primary stage, the creep rate decreases with time and reached to steady state value (secondary stage) which is followed by sudden increase which is known tertiary stage. It is known that creep compliance increases with temperature at constant stress load1. In an experimental
impacts locally to geography and ecosystems, but because of Novarupta’s status as the strongest volcanic eruption in Alaska’s recorded history, Novarupta left local as well as global impacts on earth’s climate. The Novarupta volcano eruption negatively impacted global climate by expelling a wide aerosol/dust veil of volcanic ash that decreased global temperature significantly, releasing oxides into the atmosphere, and triggering numerous earthquakes after the initial eruption. Large eruptions like
