Mae Jemison is a physician and former NASA astronaut. She is also an engineer and a scientist with a background in chemical engineering and medicine. Jemison is notable for being the first African American woman to travel in space, participating in the STS-47 mission aboard the Space Shuttle Endeavour in 1992. In addition to her work in space exploration, she has been involved in various educational and advocacy efforts related to science and technology.

A scientist who studies financial systems is typically referred to as a financial economist. Financial economists analyze how financial markets operate, the behavior of financial institutions, and the impact of policies on economic stability. They often use quantitative methods and models to assess risk and investment strategies, contributing to our understanding of economic dynamics and market behavior.

A scientist presenting information typically conveys data, findings, or insights derived from research or experiments. This can include quantitative data, qualitative observations, or theoretical models. The presentation may be structured through graphs, charts, or written reports to effectively communicate results and conclusions to an audience. The goal is often to inform, educate, or persuade others about a specific scientific concept or discovery.

Scientists may choose observational studies over experiments when it is impractical or unethical to manipulate variables or assign subjects to different conditions. For example, studying the effects of smoking on health outcomes requires observing existing behaviors rather than randomly assigning individuals to smoke or not. Observational studies are also useful for examining real-world scenarios and long-term effects where controlled experiments are not feasible.

They should try again. Then check very carefully and see if they did the experiment correctly. They may have to change their hypothesis.

Albert Einstein was a Jew from Germany.

By presenting data that contradict those conclusions

It is important to communicate because if you can not decide any thing by your own so communicate with your brother and sister or your parents. If you communicate with them to decide something then you will surely get an answer

It means that she or he has to accept that the existing hypothesis appears to be true.

Yes it is. They need to keep records of experiments, like the process of the experiment, so they can repeat it again, and the results. This helps in further research they will do and that other scientists may do. Science is all about gaining and testing knowledge, so it is critical that they record their data.
