he didn't invent it!
It was Saturn, because he thought Saturn's rings looked like ears.
Yes Galileo was very important, because if he wasn't born than we might not even now about the stars, the planets, the moon, or even about the universe. And why is that? That is because Galileo was the one whom discovered it. Galileo was also the one whom "invented" science, math, and other great things we now do in school today. Galileo was the one whom invented the telescope, the thermometer, and other great and useful things that we use in our every day lives.
Many many things people can invent.
hi
A suggested explanation that might be true and is subject to testing by further observations is
Plato placed great importance on rational processes and believed that knowledge could be attained through reasoning and logic. Medieval scholars at Oxford, heavily influenced by Plato, also valued the role of rationality but often relied on religious teachings as a source of knowledge. On the other hand, Galileo emphasized the importance of observations and empirical evidence, challenging traditional beliefs and relying on direct observations to form his scientific theories.
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
There will be a sudden change in temperature and it is likely that the thermometer may even break.
yes he did
No there isn't; closest thing might be a thermometer.
A notebook to write them down in.
You might need to use a thermometer in a lab to measure the temperature of a sample or solution, monitor the temperature of a reaction, or ensure that a process is carried out at a specific temperature for accuracy and reproducibility of results.
