No, it is not true; but some experiments were realized at Munich recently but the meaning is another. And the problem is not new: in the years 1950-1952 some British physicists (Purcell et alii) proposed a theory of negative temperatures on the Kelvin scale.

1593 and it is call The Galilean Thermometer.
It will implode and create a black hole. not really, it'll just measure the heat..
John Harrison is credited with inventing the bimetallic thermometer in the 18th century. He used two different metals with different coefficients of expansion to create a device that could accurately measure temperature changes.
To create a homemade calorimeter for measuring heat transfer in chemical reactions, you can use a Styrofoam cup as the container. Place a thermometer inside the cup to measure temperature changes during the reaction. Insulate the cup with a lid to prevent heat loss. Record the initial and final temperatures to calculate the heat transfer.
Mercury thermometer
To make a calorimeter, you will need a container to hold water, a thermometer to measure temperature changes, and insulation to prevent heat loss. You can use materials like a Styrofoam cup, a thermometer, and a lid to create a simple calorimeter for measuring heat energy.
Scientists use data from the past to create a timeline.
No.
There is NO temperature at all below 0 (zero) Kelvin, because that is the ABSOLUTE zero point, absolute zero, the point at which there is an total absence of all thermal energy. Energy can be negative, the same as mass and eg. volume of matter.
To test hypotheses, scientists create experiments.
The water thermometer was invented by Galileo Galilei around the early 17th century. He used the principle of water expanding when heated to create a device that could measure temperature accurately.
By definition, something that measures temperature is a thermometer.'Thermo-' means 'to do with heat''Meter' means 'to measure'Thermometer literally means 'A measurer of temperature'You might mean a thermostat which is a special kind of thermometer which alterers its behaviour depending on the temperature. Thermostats are used in heating systems to prevent it from getting too hot.
