Astrology: Is it scientific?
Relevant answer
Answer
Dear Doctor
"Astrology, the study of the movements and relative positions of celestial bodies interpreted as having an influence on human affairs and the natural world, has been a subject of interest and debate for centuries. While some view astrology as a form of pseudoscience, others argue that it is a valid scientific practice.
One argument in favor of astrology as a science is that it has been used for thousands of years in various cultures and societies as a means of understanding and interpreting the world. Astrology has been used to predict weather patterns, natural disasters, and even political events. The fact that it has been relied upon for so long by so many cultures and societies suggests that there may be something to it.
Another argument in support of astrology as a science is that it is based on a complex system of mathematical and astronomical calculations. The positions of the planets and stars are calculated with great precision, and the interpretation of these positions is based on a complex system of symbolism and meaning. Astrology is not just about the stars and planets, it’s about the relationship between them and the earth, and how that relationship affects human life.
Astrology also has a psychological aspect, it can be used as a tool for self-discovery, personal growth, and insight into one’s own nature. Astrology can help people to better understand themselves and their place in the world, which is a valuable benefit in and of itself.
It is also worth mentioning that astrology is not a substitute for scientific methods, it is a complementary practice. Astrology and science can work together, astrologers can use scientific data and research to support their predictions and interpretation of astrological events."

Octo-Alloy, also called Ashtadhatu, is a traditional alloy to produce religious idols, ornaments and sculptures in indian subcontinent. My question regarding the alloy is
  • According to wikipedia,( https://en.wikipedia.org/wiki/ Ashtadhatu ), the alloy consists of gold, silver, copper, lead, zinc, tin, iron and antimony or mercury . Does this alloy consisting of so many dissimilar metals undergo phase separation during casting? Are there any research papers available about microstructure of this alloy, or about phase separation prevention of this alloy?
  • Again, some ornaments, especially bangles made of this alloy are made in forms of two interwinning wires of different color. Which metals are incorporated into which wire?
  • Where can I get credible Archeometallurgical and contemporary methods of casting (temperature, composition, time)and metalworking ( embossing, scribing) of this alloy? Was this work of a jeweler, a sculptor or a metallurgist?
  • Is there any possibility that the alloy is a high-entropy alloy? Have there been any research on molecular dynamics simulation of high entropy alloy of these particular alloying elements? I have not found any in interatomic potential repository
  • Had there been any research on MEDICAL (NOT ASTROLOGICAL) benefit of using octo-alloy( more specifically its self-disinfecting capability and heavy metal poisoning hazard)?

So, what are the Pros and Cons?
Do you want to know if you will get an un-treatable disease in the future? Is that healthy for you?
What does the government want to do with your data?
If the government makes a huge discovery on your data, will they share the profits with you?
Risk of getting a disease is often modified by environmental factors- how reliable will these predictions be? will this all just be another level of Astrology?
By limiting this test to those that can pay, is there not already a bias to the higher classes of society?
What is your opinion?
Relevant answer
Answer
The whole genetics field is opening up.
There needs to be more education of the public about their rights.
And there needs to be a government panel to assess genetic issues, especially the ethical issues. And this needs to have representation from across society
Regulation and monitoring is lagging behind scientific progress
It is a dangerous state of affairs

To me, an Erdös number seems like a harmless piece of trivia, akin to having the same astrological sign as some celebrity or sleeping in the same hotel room that a famous person had once slept in. I realize that a network of linked Erdös numbers may have interesting topological properties, but other than that, do they show anything of general significance?
Relevant answer
Answer
If E(x) represents Erdős number, then
E(x): H→R
is a mapping, where H is the set of all human beings, and N is the set of nonnegative integers.
H is an increasing variable set with time.
The solution of E(x)=0 has a solution x ∈ K where K is the set of all humans who are not co-authors with Erdős and not any co-author of any co-author of Erdős up to any order!
K is a nonempty set almost all elements in H are in K except a very few.
E(x)=1 has a few numbers of solutions, that is x∈C, where C is the set of co-authors of Erdős and the cardinal number of C is 511.
Now I raise the following question:
Assume that r >1 a positive integer. Is E(x) = r solvable?
In other words Is E(x) onto?
Another important question: What is E(Erdős)?
If the answer is E(Erdős) = 0 because Erdős is not a co-author of himself.
But on the other hand: Erdős is a co-author with some Erdős co-authors, and then E(Erdős) is not zero !
Is it a paradox like that of Russell's paradox?

In the calculation to change the latitude and longitude to Cartesian (x,y,z) the first step is converting latitude and longitude to Radian. Anyone know why we have to do this and not just use the angles of longitude and latitude?
This is the instruction that i got from one of the reference:
"All latitude and longitude data must be converted into radians. If the coordinates are in degrees.minutes.seconds format, they must first be converted into decimal format. Then convert each decimal latitude and longitude into radians by multiplying each one by PI/180"
Please share if you know why we have to convert the data to rad?
Relevant answer
Answer
The sin and cos functions usually take angles expressed in radians as input.  Although this is merely a convention, its probably a good one because many problems involving angles express those angles most naturally in radians.
Of course, there are many exceptions as well.  The MATLAB programming language provides functions sind and cosd that behave exactly like sin and cos but take their inputs in degrees.  Apparently the developers of MATLAB believe that angles expressed in degrees come up often enough to justify providing the sind and cosd functions.
The bottom line is that, unless your programming language provides functions like sind and cosd, you will have to convert degrees to radians prior to applying the sin and cos functions.
The link below is a series of short videos that explore the relationship between radians and degrees and beyond.

After seeing so many questions related to astrology in RG I would like to know how many of us believe in it?
Relevant answer
Most people seem to think there is something in astrology although they would not consciously let it influence their decisions. It is nonsense to say, “I believe in it,” because belief is something you do when you have no direct experience. Astrology is something that requires experience and hands-on work to see whether it conveys any meaning or relevance.

Since we can send electromagnetic pulses from Earth to Spacecrafts out of the solar system and induce an electric current in their communication circuitry. Why can't we send more powerful pulses to induce more power to enable the  working of the spacecraft besides communication.
How feasible is my proposal?
Relevant answer
Answer
Max,
Beamed power is an old old idea.
Do you not remember the SPSS of the 70s? (I guess not...)
The plan to harvest solar power in high orbit, convert it to microwaves, and then beam those microwaves back to the Earth, was interesting.
And the idea was revived by Bob Forward's Starwisp proposal in the 80s.
There's nothing wrong with it except for:
a) The need for large emitters to reduce diffraction spread
b) The need for low-mass and efficient absorbers/converters (optical? microwave?)
It's an old trope to install laser arrays on Mercury and power solar sails to the nearby stars.
Perfectly doable - but to justify it you need deep solar missions - and I suggest that you look at the problem of providing even 1kW of power at Jupiter orbit from the Earth.
(calculate the beam spread for a plausible transmitter, and see how large your 'telescope/laser' needs to be)

 In her book, Influences: Art, Optics, and Astrology in the Italian Renaissance, Mary Quinlan–McGrath uses as one of her examples the Astrological Vault of the Sala dei Pontefici. The original version was commissioned by Leo X and apparently designed by Raphael just prior to his death in 1520. With the Sun located centrally for astrological reasons, the ordering of the remaining celestial bodies is Moon, Mercury, Venus, Mars, Jupiter, Saturn. Does anyone know of evidence as to how the sequence for Mercury and Venus was established in this case? The ordering of the planets with respect to their distance from Earth was under considerable discussion at this time.
 
 
Relevant answer
Answer
The order of the planets arises from knowledge of their sidereal periods computed by the ancient Babylonians.  They clearly recognized that closer objects closer moved faster while objects further away moved slower.  The initial order of increasing sidereal periods: Moon, Sun, Mercury, Venus, Mars, Jupiter and Saturn; the Sun was later placed in the middle of the listing. This order was later adopted by the Greeks, which was acquired, in translation, by Renaissance astronomers.
