Asked in History of Science, Science, Superstitions
What superstitious beliefs have a scientific basis?
Superstitious belief, by definition, have no scientific basis. Science requires that ideas are tested in a way that is repeatable and falsifiable. Falsifiable means that there must be a way that the test shows that a stated belief is not true, while most superstitions rely on metaphysical entities or powers that are so vague they can not be dis-proven. Here are some examples of superstitions, and where they may have come from. Breaking a mirror is seen as seven years of bad luck from...

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. ...

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. ...
Asked in Chemistry, History of Science, 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. ...
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. ...

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. Answer: 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...

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 . ...

Asked in History of Science, Evolution
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...
Asked in Chemistry, History of Science
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...
Asked in Biology, History of Science, Taxonomy
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. ...

Dimensional formula of capacitance?
The unit, Farad, is Coloumb / Volt, so the dimensions are charge / voltage. To reduce to base SI units: Coloumb is ampere x second. Volt is joule / coloumb. Joule is newton x meter. Newton is mass x acceleration, that is, kilogram x meters / seconds2. ...

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). ...
What did Hugh Bennett do on April 14 1935?
I don't know about April 14 - HOWEVER -- - When the Soil Erosion Service was established as part of the United States Department of the Interior in September 1933, Bennett became the director. He continued to speak out on soil conservation issues, especially through the Dust Bowl years, and eventually influenced the passage of the soil conservation act of April 27, 1935, which created the Soil Conservation Service at the USDA. ...
