Each of these scientists made significant impacts in their respective fields, laying the foundation for future scientific advancements.
What are the advantages of being a forensic scientist?
Some advantages are that you get respect from the law and you should feel 'happy' that you have solved a murder or what ever you are doing that field. Also... you can get to work out who did the murder, and how, what is the murder weapon, and if it was a gun or a long distance weapon where it came from. X
What did Alessandra Volta say in his life?
Alessandro Volta was an Italian physicist who is known for inventing the electric battery. One of his famous quotes is "The language of experiment is more authoritative than any reasoning: facts can destroy our ratiocination—not vice versa." This quote emphasizes the importance of empirical evidence in scientific research.
What is an element that scientists measure how old a dead thing is?
Scientist test this by measuring the radioactive decay of Carbon 14 to Nitrogen 14. Good for up to 70,000 years.

How do you put a broken candle back together?
Repairing a candle use a match/lighter to melt both broken sides and stick them back together. It will probably always be a little weak in that spot, but you may be able to make it look almost 'like-new.'
Which scientists discovered that toys use the principle of centrifugal force?
There isn't a specific scientist credited with discovering that toys use the principle of centrifugal force, as this concept has been known and applied in various fields for a long time. Toys such as spinning tops, yo-yos, and fidget spinners utilize centrifugal force to stay balanced and spin for longer periods of time.
Diagram of clinical thermometer?
A clinical thermometer typically consists of a long, narrow, glass tube with a bulb at one end filled with mercury or alcohol. The tube is marked with a temperature scale in degrees Celsius or Fahrenheit, with divisions marked on it. The mercury or alcohol expands and rises up the tube when heat is absorbed, indicating the temperature.

What are facts about Albert Einstein's history?
Albert Einstein was a very good man. He was born on March 14, 1879. He was born and raised to a German family, having very strict but good parents. He started out a very intelligent kid and as he went on he got smarter and smarter and started realizing what he wanted to do when he got older. He took several test at different University's earning lots of different awards. As he got older he started putting his brain towards some good he invented a few things such as the light bulb. When Albert was younger he worked in a few different places including a small shop with an older family friend. He started out and ended a good beginning and kept following his heart, Alber Einstein died a greatly remembered man!
These facts are 100% true and great reliable sources. I only put that because have of the stuff people put on these sights it is fake or made up and people still use that information, but most of the time its fake.
- Thank you very much!!(:
Did Albert Einstein work with another scientist?
Yes, Albert Einstein collaborated with other scientists throughout his career. One notable collaboration was with physicist Niels Bohr on the development of quantum theory. Einstein also corresponded and exchanged ideas with many other prominent scientists of his time.
What system of units do scientist use to find the properties of matter?
Scientists typically use the International System of Units (SI units) to find the properties of matter. These units provide a standardized way of measuring various physical quantities such as mass, length, time, and temperature. This allows for consistency and easier communication of data within the scientific community.
What did Albert Einstein do to make him famous?
First He Changed The The World In Mathe And Science.
Then When People Came To Take His Picture He Stuck His Tongue Out To See If That Would Drive Away Them But Ironically That Picture Is Now One Of Most Well Know Pictures.
Why do scientist seek to discover new laws of the universe?
Scientists seek to discover new laws of the universe to better understand how the world works and to improve our ability to predict and control natural phenomena.

By uncovering new laws, scientists can push the boundaries of our knowledge and drive progress in various fields.
Inventions of Albert Einstein?
Albert Einstein was a theoretical physicist, not an inventor (although he did once work in a patent office). While he did not invent things himself, his theoretical work was essential for a number of inventions that other people invented, including the atomic bomb and the laser.
