What superstitious beliefs have a scientific basis?

As of 2007 Atheism has been proven to be a religion with zero honesty or truth! Atheism is all fiction; confirmed by honest scientific tests! The Atheists have also lost in the Supreme Court! God won!

Every single sentence of history in the honest Bible has anywhere from three to over 250 records found to confirm each line! The Bible is all truths, facts!

History of Science

Who discovered vaccines and how?

There is a history of smallpox inoculation that goes back as far as 1000 AD in China, Africa, and Turkey. However, the person credited with creating the first vaccine is Edward Jenner, an English scientist who pioneered one for smallpox in 1796. His breakthrough came from taking pus from a blister of someone infected with cowpox and using it to inoculate another person, thus preventing smallpox in that person. He developed this treatment after hypothesizing that dairy workers were rarely, if ever, infected with the deadly smallpox virus because most of them were already infected with cowpox, which has a very mild effect on humans.

How many branches of science are there?

There are innumerable branches of science. No matter how small a field is, is a branch and there are new fields opening every day. Just look at science journal publisher and there hundred of subjects just a for a limited area like subatomic physics. Big branches include physics, chemistry, and biology where there all sorts of overlapping subjects like chemical physics.

Marie Curie

Who was the husband of Mary Curie?

The husband and scientific collaborator of Marie Skłodowska-Curie was Pierre Curie, a French physicist who was a pioneer in the fields of crystallography, magnetism, piezoelectricity and radioactivity, and a Nobel laureate. He received the Nobel Prize in physics with his wife in 1903.

Periodic Table

Who created the periodic table?

The first periodic table was developed by Dmitri Mendeleev in the mid-19th century.He wasn't the only person thinking along those lines ... both John Newlands and Lothar Meyer had proposed similar ideas

However, Newlands was largely criticized and ignored at the time, and Meyer didn't make any predictions, so Mendeleev's table (which did make predictions about the properties of several as-yet-undiscovered elements) is generally regarded as the first.

Botany or Plant Biology

What is a transpiration in a plant process?

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. Transpiration also includes a process called guttation, which is the loss of water in liquid form from the uninjured leaf or stem of the plant, principally through water stomata.

René Descartes

Why did René Descartes believe in god?

One of his reasons for believing in god is that he knows (or thinks) that God is perfect. Since perfection includes existence, he therefore assumes that God must exist.


Descartes made a series of increasingly unsupportable suppositions to back up his beleief in God:

1. I exist (A supportable statement for an individual - Cogito ergo sum)

2. I have in my mind the notion of a perfect being (The idea that anyone can develop an idea of a perfect being is not provable. The Aztec may have thoght their bloodthirsty gods perfect as well)

3. An imperfect being, like myself, cannot think up the notion of a perfect being (There is no proof although it is believable that humans are not perfect and it is debatable if the idea he has of a perfect being is indeed perfect)

4. Therefore the notion of a perfect being must have originated from the perfect being himself (This is a flight of fancy)

5. A perfect being would not be perfect if it did not exist (Buddhists, for example see perfection in the loss of being)

6. Therefore a perfect being must exist (This does not follow from any of the above statements)

What is an allele and what is a nasty allele?

Allele is word used by Mendel for counter parts of an elementon later called factor and renamed as gene e.g. T and t are alleles for a gene that controls height in pea plant .Nasty allele is not biological term .

Note word elementon is technical term used by Mendel , it is not element used in Chemistry .

Why does a ball fall to the ground?

Because God made all this way. As it is.

If someone decides to break a law, that is their decision.

History of Science

Is evolution reversible?

Answer 1

Evolution is not a process that can be reversed. The core principle behind evolution is that traits with a positive impact on survivability or reproduction tend to passed on to subsequent generations. Evolution itself is merely the slight alteration of a species gene pool over many generations. Perhaps you can see that the question "Is evolution reversible is something of a misnomer. Is the process by which you change something reversible In certain processes the thing that is changed can be returned to its original state, but this process also requires change. If you intended to reverse an evolutionary process the only way you could do so would be through evolution. This type of process has no non-reflexive logical inverse.

Perhaps what the question intended to ask was whether a species could "revert" back to a "less evolved" state. An example to explain this would be the reversion of humans to a more apelike genetic structure. This is certainly possible. If traits that were more apelike positively impacted the survival rate or the reproduction rate of the humans that had them than humans would begin to evolve to become more and more like our simian ancestors.

Answer 2 : There are certain examples of reversal in evolution .Most familiar trend can be seen in evolution of Dinosaurs which were of small size in Triassic period , evolved to maximum size in Jurassic period ,and again decreased in size in Cretaceous period .

Answer 3: The process of Evolution doesn't have a "direction", it doesn't favor one type of organism or trait as being "higher" than another. So in a broad sense evolution simply goes where environmental conditions dictate, there's no backward (reverse) or forward.

Could traits that were once non-adaptive reappear in a population if environmental conditions changed to make them adaptive again? Yes

Can an individual organism reacquire older traits that were not part of it's original genetic makeup? No

Do some older traits occasionally reappear in vestigial form in some individual organisms. Yes (there are instances of humans being born with a short tail etc.)

Answer 4

Evolution is basically a stochastic phenomenon. In order for evolution to "back-track", every single change in the genome that had occurred would have to be reversed in the exact reversal of the order that they occurred in. This is so extremely unlikely to ever occur that, were it observed, we would have to conclude aliens were pulling our legs.

But although evolution is not reversible, it is possible for traits to evolve a similarity with an earlier form. Consider for instance the fish-like shapes of whales: they evolved from land-dwelling mammals, which in turn can trace their ancestry back to early fish. Same shape, completely different genetics.

Answer 5

If you cloned an extinct animal, it might count as evolution going backwards. Not sure about that though, cause it's a pretty philosophical question.

What does a bohr model of iron look like?

Hydrogen the simplest of all elements, was investigated most extensively both experimentally and theoretically. As long ago as 1885, Balmer succeeded in obtaining a simple relationship among the wave numbers of the lines in the visible region of the hydrogen spectrum.

The first quantitative correct derivation of the Balmer formula on the basis of an atomic model was given by Bohr (1913), in his theory of the hydrogen atom. Those theory has played such an important role in the development of atomic physics that even though it has been modified and extended by the later developments in quantum mechanics, it will be worthwhile to present the original simplified theory.

In 1913, Niels Bohr proposed a model for the hydrogen atom which retained the earlier nuclear model of Rutherford but made further stipulations as to the behavior of the electron. A dramatic explanation of the Rydberg spectral expression resulted.

What is meant by the biological hierarchy?

The biological hierarchy refers to the different levels of classification from domain to species (eight levels). The three domains are Bacteria, Archaea, and Eukarya, while the types of species number in the high hundred thousands or low millions. Each organism can be classified into a race and then taxonomically into species, genus, family, order, class, phylum, kingdom, and then domain.

What would life be like without penicillin?

Simple scrapes, cuts and internal injuries would slowly build and ravage our body both from the inside-out and the other way around. There are certain strains of bacteria that are resistant to almost every form of antibiotic. 2 of them may cause a lot of damage in the near future: MRSA (Methicillin Resistant Staphylococcus Aureus) and VRE (Vancomycin Resistant Enterococcus).
