There is limited footage of Stephen Hawking before his illness, as he developed ALS in his early 20s. However, there are some clips of him as a young man giving presentations and speaking at events. Hawking's groundbreaking work in theoretical physics and cosmology began before his illness and continued throughout his life.

The ancient Greeks, particularly Empedocles, proposed the idea that all matter was made up of four elements: earth, water, air, and fire. This concept influenced early ideas about chemistry and alchemy.

Isn't it so they can monitor and look at any trends. Also for historical references probably. ALso it probably helps them predict any future earth quakes becasue they monitor the conditions and then they can evacuate when there are predictions because as technology increases, they have more tools to process data but they need to record so that in the future hwen they have even better tools, they can better analyse.

Kepler thought that the planets were all rotating on giant celestial spheres which were stacked between the 5 platonic solids.

You can read about this in his book: Mysterium Cosmographicum

Copernicus thought the planets orbits are circular, kepler decided they are elliptical. This however took him many years to discover, as also he thought that they were circular for a very long time.

It was when one of the top astronomers of that time died (Tycho Brathe) and he got hold of his data that Kepler could finally make accurate calculations.

From these calculations he found that the planets must have elliptical orbits, and he chose to believe Brathe's data rather than the age old belief in circular orbits.

Max Planck's constant, denoted by the symbol h, is a fundamental physical constant used in quantum mechanics to relate the energy of a photon to its frequency. It has a value of approximately 6.63 x 10^-34 Joule seconds.

A person who studies that category is called an astronomer.

Lavoisier's discovery, known as the law of conservation of mass, states that in a chemical reaction, the total mass of the reactants is equal to the total mass of the products. This implies that mass cannot be created or destroyed in a chemical reaction, but only rearranged.

Both Aristotle and Galileo triggered a Paradigm Shift.

Galileo mainly influenced the world of 'scientists'.

To be honest a universe with or without earth as centre doesn't matter that much

Probably Newton made more difference, only would there have been a 'Newton' without Galilei

But also Newton mainly influenced the world of 'scientists'.

Aristotle cause a Major Paradigm shift in The Western World. A reality Redesign.

One that changed the view about reality from a holistic view (The One, The Fire, The All, ..) in a creationist view. Physical common sense reality + supreme God.

Scientists should report their results once they have completed their research, analyzed the data, and drawn conclusions. It is important to share their findings in a timely manner to contribute to the scientific community's knowledge and transparency.

Scientists discovered many things from the two Voyager missions in 1980 and 1981. They discovered a hexagonal pattern of circulation above the northern pole. They learned more about Saturn's rings and their complexity, finding more "gaps" in the widest rings. They found even more of the numerous small moons that orbit the planet or lie within the rings. Voyager 1 also made the first close observations of the moon Titan.

Using precise data, reliable instruments, and rigorous mathematical models are essential for scientists to make accurate calculations. Additionally, conducting repeatable experiments and thorough peer review processes can help validate the accuracy of their calculations.

Democritus gave a theory, but Aristotle shut him out. Everybody forgot about this, and there was no one looking into this, no progress was being made.

Yes, metals used for jewelry like platinum and gold have low reactivity, making them resistant to tarnishing and corrosion. This is why they are popular choices for jewelry as they maintain their luster and appearance over time.

Nikola Tesla was a Serbian-American inventor, electrical engineer, mechanical engineer, and ... Nikola completed primary school, followed by middle school. ... Tesla did, however, attend lectures in philosophy at the university as an auditor ...

No, Robert Koch did not contract anthrax through his experiments. He took strict precautions to protect himself and others while working with dangerous pathogens, such as using protective gear and following proper safety protocols.

Antoine Lavoisier defined an element as a substance that cannot be broken down into simpler substances by chemical means. He proposed the Law of Conservation of Mass and the concept of chemical elements in his work on the nature of matter.

Scientists believe that chemical evolution occurred around 4 billion years ago, shortly after Earth was formed. This process involved the formation of complex organic molecules from simpler compounds through reactions such as polymerization and the assembly of molecules on mineral surfaces.

1. it was electrons

Pebble is primarily composed of silicon dioxide, which is not soluble in water. Therefore, pebbles are considered insoluble in water.

Robert H. Goddard is considered the first scientist to successfully launch a liquid-fueled rocket in 1926. He used a combination of liquid oxygen and gasoline as propellants in his rocket experiments.

Scientists hypothesize that chemical events preceded the origin of life on Earth because these events could have provided the necessary building blocks for life to form, such as organic molecules and simple compounds. By understanding how these chemicals interacted and evolved over time, scientists can gain insights into the origins of life on our planet.

Scientists use measuring instruments to accurately quantify, analyze, and record physical quantities such as length, mass, temperature, and time. These instruments help scientists collect precise data, make informed decisions, and validate their hypotheses through empirical evidence. Ultimately, measuring instruments are essential for ensuring the reliability and reproducibility of scientific findings.

One of the main defects of the Bohr atomic model is that it does not explain the spectra of atoms with more than one electron accurately. It also cannot account for fine details in spectral lines caused by interactions between electrons. Additionally, it does not incorporate the wave nature of particles, as described by quantum mechanics.
