Was quantum shell theory disproved?

Quantum shell theory was first proposed by the physicist Niels Bohr as an explanation of the unexpected complexity of the spectra of hydrogen and various other atoms. According to Bohr each quantum shell represents a certain state of energy, attributed to the electron orbiting within that shell. So an electron within the lowest shell would be orbiting at the orbit closest to the nucleus, and thus has the least energy, whereas an electron within a higher shell would be orbiting at the next closest orbit to the nucleus, and thus has a bit more energy by a discrete amount as given by Planck. However, it was noted that this explanation, although it worked perfectly with hydrogen, became more and more inaccurate as the atomic mass of the element in question increased. Therefore, later the electrons and nucleic particles in Bohr's quantum shell theory, with its discrete, pointlike particles, was augmented by another description from wave mechanics, based on Schrodinger's equation, that envisioned Bohr's discrete particles as a sort of vibrating instrument- although what exactly it is that vibrates, and what exact relation it bears to the particle, did not seem to be clear at the time (and is still ambiguous to some extent now). After the assertions of wave mechanics were successfully tested (such as the predicted diffraction of electrons etc.), its description was recognized for the wonder it was, and nowadays replace quantum shell theory as a more accurate and complete description for the working of the atom. This is not to say, however, that quantum shell theory was disproved, just as the dawn of relativity does not disprove Newtonian mechanics. All the modern quantum mechanics, with its powerful wave equation, has done was to replace Bohr's more naive view with a more mature, complete and accurate understanding of the working of the atom. The fact that Bohr was superseded does not mean he was wrong, merely that his description was not complete or nearly accurate enough to account for the phenomena observed. Even now, because of the simpler maths, it's still used as a introduction to the weird wonders of the quantum world.

What chemist is given credit for discovering oxygen?

Oxygen was first discovered by Swedish pharmacist Carl Wilhelm Scheele in 1772 by heating mercuric oxide and nitrate salts.

(But don't try this at home: both very toxic experiments).

Also there was a main quarrel about the 'first' claim between Priestly (VIII-1774) and Lavoisier (1774, later) and Scheele (letter in IX-1774, but found after his death)

Is evolution a random process?

Answer
No. It is far from random, there is nothing random about it. If I were to race my three year old nephew I would win, easily. I am faster and stronger and I have more stamina. The outcome of the race would not be random, it would be inevitable. Evolution is the same. The organism that is better equipped to reproduce will have more success and therefore become dominant and potentially drive other strains or species out of existence. The only random element is the mutations that cause one animal to be more fit than another. Most are harmful and die out in a generation or some, some are neutral and make no real difference (these are the variations we look at for DNA tests in court) and a few are beneficial. The good ones are passed down and over time an accumulation of good changes causes the organism to become a different sort of organism. This could be likened to poker. One hand is clearly better than another but the cards are dealt at random. Still, the best hand wins and the worst player is out of the game the soonest. Hope this helps!

Answer - Yes
Evolution is very random as it is based on mutations in the genetic code of organisms, although this process is random natural selection is NOT random and it is one of the main principals of this theory.

Answer 3

Yes, and no. Evolution is random in the sense that the solutions it produced (metabolic paths, body shapes, and so on) were by no means necessary outcomes, but produced by happenstances of genetic chemistry and chaotic environmental pressures. Should we rewind the clock and reset life to its most primitive form, there is no reason why the same lifeforms should evolve again. Evolution is non-random in the sense that whatever solution was produced would still have to have met the same criteria for survival and replicative ability. To summarize: natural selection limits the randomness of genetics, but by no means eliminates it.

What do you mean when you say that neither ecological succession nor natural selection is progressive?

When saying that neither ecological succession nor natural selection is progressive, it means that neither process inherently leads to more complex, advanced, or improved organisms or ecosystems. Instead, both processes result in changes that are driven by environmental conditions and can lead to different outcomes depending on various factors.

Is God choosy on which religion you follow?

He is indeed choosy: Exodus 20: v3 "Thou shalt have no other God before me" -this invalidates most other religions. John 14: v6, "Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me." - This eliminates all other religions == According to the followers of god Khrishna, god is not choosy. Khrishna teaching; "It does not matter to whomever god one prays for, it is the Lord Khrishna who answers them anyway." Or something like that.... == Which god? == Actually, the Jews are God's "chosen people", but He established a different covenant with the New Testament, one that fulfills the prophecy of the Old Testament.

How did Charles Darwin and Alfred Wallace gather information which then led them to formulate the concept of natural selection?

I don't know about Wallace, but Darwin spent a lot of his time in the Galapagos Islands where he saw what he thought was natural selection in action without interference from, or as a response to, outside sources like mankind.

What evidence is there to support the theory that a 'manager leads best when his people get behind him'?

== == * Many good companies are always looking for ways to create good management that improve leadership and good communication skills with their employees. It is not an easy task being a Manager because he/she has to deal with many different personalities and debates within his employees and be fair yet stern. A good Manager learns to roll up his/her sleeves and get down to the level of his/her employees when time permits and always has his pulse on the working abilities of his employees. A Manager should be approachable to resolve problems and in most cases any employee with a problem should be heard and treated with dignity. Hard work and laughter between Manager and employee go a long way. * There is an old saying in management training that goes like this: If the employees aren't following....the manager isn't leading. The key has to do with the way the manager routinely communicates and interacts with those reporting to him/her. For example: Does he/she maintain or enhance their self esteem...or just browbeat and intimidate? Does he/she really listen...or is he/she just waiting to talk. Does he/she regard the employee's feelings or openly criticize them in front of other employees? Does the manager ask for help or input in making decisions?...or just assume he/she has all the answers. Dictatorial management is short-term effective at best and invariably ruinous in the long term. One of two things happens...the manager fails or the employees subsequently help him/her to fail!

How did Darwin think geographical location influenced evolution?

Darwin believed that geographical isolation led to the formation of new species through the process of natural selection. He observed that isolated populations of organisms in different geographical locations faced unique environmental challenges, resulting in adaptations that eventually led to the formation of distinct species. This idea of geographic isolation as a driver of evolution is now known as allopatric speciation.

How many languages has the origin of species been translated into?

"The Origin of Species" by Charles Darwin has been translated into over 70 languages. It is considered one of the most translated scientific works in history.

What is liberal humanism theory?

El humanismo surgió como movimiento intelectual en Europa durante el siglo XV, para promover la formación integral de las personas. Por eso los humanistas solían reunirse para compartir experiencias y debatir. Algo de esto último aún se mantiene, por ejemplo, en la actividad de los Ateneos en España. El humanismo también ha sido un movimiento renacentista que se propuso retornar a la cultura grecolatina para restaurar los valores humanos.

How did Charles I influence his nation?

Charles I of England's autocratic rule and conflicts with Parliament led to the English Civil War, ultimately resulting in his execution. He imposed unpopular policies and taxes, leading to widespread unrest and Royalist versus Parliamentarian division. His actions ultimately sparked a shift in power dynamics and paved the way for the establishment of a constitutional monarchy in England.

What idea of malthus did Darwin extend to all population?

Darwin extended Malthus's idea of competition for limited resources to all populations, suggesting that individuals within a population with advantageous traits are more likely to survive and reproduce, passing on these traits to their offspring. This process, known as natural selection, drives the evolution of species over time.

How did the ides of Thomas Malthus influence Darwin's thinking about evolution?

Thomas Malthus's idea of population growth outstripping resources and leading to competition for survival had a significant impact on Darwin's thinking. This concept provided Darwin with insight into the struggle for existence and natural selection, which became fundamental principles in his theory of evolution. Darwin incorporated Malthus's ideas into his own work to explain how species evolve and adapt to changing environments through the process of natural selection.

Who applied Charles Darwin's biological laws of natural selection to society and business asserting that those people and businesses that were the strongest fittest and most moral would survive?

That idea was popularized by Herbert Spencer, who applied the concept of "survival of the fittest" from Darwin's biological theory of natural selection to society and business. Spencer believed that individuals and businesses that were the strongest, fittest, and most moral would thrive and succeed in society and the marketplace.

How the ideas of other scientists influenced Darwin ideas and ultimately shaped his philosophies?

Darwin was influenced by ideas from other scientists such as Lamarck's theory of acquired traits and Malthus's principle of population. These ideas contributed to Darwin's concept of natural selection as the mechanism for evolution. Ultimately, Darwin's observations and synthesis of these ideas led him to develop his theory of evolution by natural selection, which revolutionized the field of biology.

What is the philosophy of survival of the fittest?

Survival of the fittest is a concept in evolutionary biology that suggests organisms best adapted to their environment are more likely to survive and pass on their genes. It is often associated with natural selection and the idea that competition drives evolutionary change. This concept has been used to explain the diversity of life and the adaptations of species over time.

How did Charles Darwin influence the insanity defense?

Charles Darwin influenced the insanity defense by proposing that mental illness was a result of biological factors rather than moral weakness or supernatural causes. This shifted the understanding of mental illness towards a more scientific and medical perspective, which eventually influenced legal systems to consider mental illness as a mitigating factor in criminal cases. Darwin's work contributed to the development of the modern concept of insanity as a defense in criminal trials.

Who suggested that children would develop into generous and moral individuals if they were left to their natural tendencies?

Jean-Jacques Rousseau, an 18th-century philosopher, proposed the idea that children would develop into generous and moral individuals if they were left to their natural tendencies in his work "Emile: On Education." Rousseau believed that children possessed innate goodness and would naturally grow into virtuous beings if allowed to develop without societal influences.

How does the concept of natural rights fit into the social contractual theory?

The concept of natural rights is central to social contract theory as it posits that individuals possess inherent rights that should be protected by society. These rights, such as life, liberty, and property, form the basis of the social contract, which outlines the mutual obligations between individuals and the government. The social contract theory argues that individuals agree to follow certain rules and give up some freedoms in exchange for the protection of their natural rights by the government.

What did Darwin's dad want him to be?

Darwin's father, Robert Darwin, wanted him to become a physician. He sent Darwin to study medicine at the University of Edinburgh, but Darwin found the lectures on surgery to be particularly gruesome.

What influence did Darwin have on the formation of the insanity defense?

Darwin's theory of evolution influenced the concept of mental illness by promoting the understanding that mental illnesses were biological and not solely the result of moral failings or supernatural forces. This shift in perspective led to the development of the insanity defense in legal systems, which takes into account the impact of mental illness on a person's ability to understand their actions and the consequences. Darwin's work contributed to a more compassionate and nuanced approach to mental health in the legal context.

When Charles Darwin set sail on the HMS Beagle what were the prevailing ideas in society particularly regarding the origins of the Earth and of human beings?

They thought that the Earth and all the creatures have always been the way they are. All the animals on the planet were there in the beginning. Darwin later disproves this because animals are constantly changing and the Earth was really different in the beginning.

What is the belief that inequality in society is the result of natural selection based on individual capacities and abilities?

You have two things confused. Societies working this way is the concept of Social Darwinism, a misguided attempt to explain societal differences by some form of group selection. Individuals do vary in their capacities and abilities and this is what natural selection is selecting and you confuse equality of identity with equality of morality under the law.

How would Charles Darwin explain depression?

English:

No less interesting is the discovery and scientific justification for intermediates forms in the evolution theory of Charles Darwin. These intermediates forms have been found, but information about this has not been published.

In addition, there is a scientific theory that explains the origin of life on planet Earth. This theory is most corresponds to modern scientific knowledge in many fields (branches) of science, but it this a scientific theory also has not been published.

По-русски:

Не менее интересным является нахождение и научное обоснование промежуточных форм в теории эволюции Чарльза Дарвина. Эти промежуточные формы уже найдены, но информация об этом не опубликована.

Кроме того, имеется научная теория, которая объясняет происхождение жизни на планете Земля. Эта теория наиболее соответствует современным научным знаниям во многих отраслях науки, но эта научная теория также не опубликована.

Was Charles Darwin's theory about revolution a lie?

Did you mean "Evolution"?

No, it was the explanation of the species problem at the time and has been refined and strengthened in the last 157 years so well that it has met all challenges head on and surmounted them with flying colors.

Creationism, regardless of stripe, is the actual lie.
