How do scientist learn from their observations?

Scientists learn from their observations by analyzing patterns, making connections between different observations, and forming hypotheses to explain their findings. They then design experiments to test these hypotheses and refine their understanding of the natural world through observation and experimentation.

What are the two methods scientist use to obtain empirical evidence?

Scientists obtain empirical evidence through observation and experimentation. Observations involve gathering information through senses or instruments, while experiments involve manipulating variables to test hypotheses and gather data. These methods help researchers make objective conclusions based on evidence.

Who was the German rocket scientist who led the American space program to the moon?

Wernher von Braun was the German rocket scientist who led the American space program to the moon. He was a key figure in developing the Saturn V rocket that propelled the Apollo missions to the moon.

Is it possible to prove a hypothesis by conducting rigorously controlled experiments?

Rigorously controlled experiments can provide evidence to support or refute a hypothesis, but they cannot definitively prove a hypothesis. Scientific hypotheses are continually evaluated, refined, and occasionally rejected based on new evidence and further experimentation.

What kind of objects would scientist study to learn about the composition of the Oort cloud?

The Oort cloud is spherical cloud of or shell comets nearly a light-year from the Sun. Comets are disturbed from this cloud by gravitational attraction and other factors and pass into the area occupied by the inner planets (Earth for example). Scientists then can observe these transient bodies to determine the composition of material in the Oort cloud.

Did Alexander Fleming have any brothers or sisters and what was there names?

Yes, he had several sisters, brothers, and half-brothers and sisters. His father, Hugh Fleming, married Grace Sterling and Grace was his mother. Seven children in all, Including Jane Fleming, Richard Fleming, and also his older brother Hugh Fleming.

How do scientists predict comet movement?

Almost all known comets follow an elliptical or circular path. This means that, over time, they return to our solar system at regular intervals. Astronomers identify each comet, and track its movement while it's in our 'neighbourhood' - then use the data to predict when it will next return.

What was arno penzias's scientist contribution to understanding the universe?

Arno Penzias, along with Robert Wilson, discovered the cosmic microwave background radiation, which provided strong evidence for the Big Bang theory. This radiation is a remnant from the early stages of the universe and has been essential in shaping our understanding of the universe's origin and evolution. Penzias and Wilson's discovery was awarded the Nobel Prize in Physics in 1978.

What did Jean Baptiste Lamarck discover?

Jean Baptiste Lamarck proposed the theory of inheritance of acquired characteristics, suggesting that traits acquired during an organism's lifetime could be passed on to its offspring. He also investigated the relationship between organisms and their environment, contributing to our understanding of evolution.

Why do scientists classif different species into th same genus?

A genus is a part of a family and each genus contains animals which are very closely related.

genus or genes as we can also say contains animals which look the same and have the same charectaristics , but can be told apart because of their colours , and are therefore sub divided into species.

For example :

a red eyed tree frog and an eurasian green tree frog belong to the same genus - frogs but are of different species.

What scientist studies rocks on other planets?

A planetary geologist studies rocks on other planets. They analyze the composition, structure, and history of rocks to understand the geology of other planets in our solar system.

Where do scientists perform their work?

Scientists perform their work in various settings such as laboratories, research institutions, universities, field sites, and even in some cases, corporate offices. The location depends on the type of research being conducted, with some scientists also working in government agencies or non-profit organizations.

Did Edwin Hubble ever invent anything else than the Hubble telescope?

Edwin Hubble did not invent the Hubble Space telescope (HST).

Edwin Hubble had been dead for forth years before HST was operational.

HST is named after him. He was an astronomer.

(See related links.)

If anything can be said to be invented by Hubble, it is to be found in a few ideas that came out of a few discoveries he made such as the existence of the Universe.

Only at the turn of the century with the construction of gigantic telescopes of almost a meter in diameter was it possible to distinguish the blobs known as nebulae as being outside of our galaxy. In the 1920s Hubble's observations confirmed the existence of other galaxies in the universe outside of our own galaxy, an idea that existed, but was controversial and lacked evidence earlier. (Earlier, the universe was thought to be infinite, but mostly empty except for our own little neighborhood of a few billion stars in the Milky Way. As always, we were the center of the Universe.)

In the next years, Hubble expanded this with data from others to quantify the observation that the Universe was expanding. (Now called Hubble's Law.) This led, of course, to the first data supporting the Big Bang theory suggested in by Georges Lemaître in 1927.

How do scientist study ancient atmosphere?

Scientist study ancient atmosphere by collecting pieces of the early atmosphere that were trapped and formed into rocks and minerals. They take these piece and crush them up to clearly see them and analyze them. Rocks and fossils allow scientist to collect more information of what the atmosphere looked like when they were created.

How do scientists use comparative anatomy to study evolution?

Comparative anatomy is the investigation and comparison of the structures of different animals. Scientists use comparative anatomy to study the difference between species and how they are alike in other ways.

By comparing the similarities and differences between a number of species, scientists can then construct a picture of their evolutionary relationships.

Why did other scientist not believe Alfred Wegener hypothesis?

Other scientists did not believe Alfred Wegener's hypothesis of continental drift in the early 20th century because he did not provide a plausible mechanism for how continents could move through the oceanic crust. Additionally, Wegener's evidence supporting his idea was largely based on geological and fossil similarities between continents, which were not considered strong enough to support such a revolutionary idea at the time. It wasn't until the mid-20th century, with the development of the theory of plate tectonics, that Wegener's hypothesis gained widespread acceptance.

What do scientists use to represent things they cannot directly study?

Scientists use models to represent things they cannot directly study. Models are simplified, abstract versions of complex systems or phenomena that help scientists make predictions and understand how these systems work. They can range from physical models, such as scale replicas, to mathematical models and computer simulations.

What kinds of tools do scientists use to find new planets?

Scientists use a variety of tools to find new planets, including ground-based telescopes, space telescopes such as Kepler and TESS, and techniques like the transit method and radial velocity method to detect exoplanets. Radio telescopes and gravitational microlensing are also used to discover planets outside our solar system.

Why do scientist use mirrors?

Scientists use mirrors for various purposes such as reflecting and redirecting light in experiments, telescopes, microscopes, and laser setups. Mirrors are also used for focusing light, creating optical illusions, and in devices like periscopes for viewing objects around corners. Additionally, mirrors are utilized to calibrate and align optical systems accurately.

What is the use of Hertzsprung Russell diagram?

The Hertzsprung-Russell diagram is used by astronomers to plot the luminosity of stars against their surface temperature or color. This allows scientists to analyze the evolutionary stage, age, and properties of stars, as well as understand their life cycle and predict their future evolution. It is a crucial tool in stellar astronomy for classifying stars and studying stellar populations.

Which scientist proposed the law of octaves?

The scientist who proposed the law of octaves was John Newlands in 1864. He noticed that when the elements were ordered by atomic weight, every eighth element had similar properties, similar to the musical concept of octaves.

How does scientists organize data?

Scientists organize data using various methods such as creating tables, graphs, charts, and databases. They may also use statistical analysis to identify patterns, trends, and relationships in the data. Proper organization of data helps scientists to draw meaningful conclusions and make informed decisions based on their research.

Is Ms Colette Stancel a famous scientist?

There is no widely recognized scientist named Colette Stancel, therefore she is not famous in the scientific community.

What is the name is people who studies the stars?

People who study stars are called astronomers. They observe and analyze celestial objects and phenomena, including stars, planets, galaxies, and more, to better understand the universe.
