Questions related to Physical Sciences
I'm a grade 11 student from the Philippines and our school is currently holding online classes. Quarantine restrictions render us with no access to physical laboratories to hold tests and experiments in. We have been interested in the field of Physical Science and considered doing a comprehensive meta-analysis. However, our research coordinator discouraged us from choosing to do so. Is it still possible for us to pursue this topic? And what specific research topics could be feasible for us to do? Answers and suggestions are very much appreciated.
Physics is one of the physical sciences. The two other physical sciences are chemistry and astronomy. Astrophysics is the branch of physics that deals with space and celestial bodies.

Yep. RG is equating science with experiments. There may be those who like this, but experimentation is NOT THE ENTIRE SCIENTIFIC METHOD (and I would argue that experimentation is THE LEAST OF IT -- especially if one is developing a new perspective and approach). RG appears to have no appreciation for "just" verified observations -- even though that may be exactly what really new discovery looks like . Those observations may, in time (but not right away), be followed by experimentation. Verified observations by themselves may be very important and all we have for some time (in some new areas/kinds of investigation).
The outrageous bias of RG is so great that they now hide the Project Updates (of the Log) with multiple queries about one's experiments and hypotheses -- as if all good, clear hypotheses could be put "in a nut shell" (in a small "blank", with little context) AND that experiments are all that matter (or at least all that deserves several special headings). How about a heading for: "Verified Observations"?
I would ask: What experiments did Einstein do to lead and come up with his understanding of the universe? Did he start with experiments? NO!! He started with observation and MATH (which is basically verified observation). True, eventually some experiments were done to VERIFY HIS IMPORTANT OBSERVATIONS -- but all this did NOT begin with experiments..
And, all of this is not to mention major swathes of Biology. Come on, give us a break.
Referencing is very useful in science, offering support for evidence, reasoning, ethos, leads to a more concise text, and other advantages.
But, quoting the words of another, which is widely used in the humanities and philosophy, to convey, e.g., gravitas and erudition, seems often futile and counter-effective in science. One should rather trust his own words, and calculations. A worrisome point-of-failure in papers, and not by the authors!
In general, also, inlined quotes have a lifetime, as anything else. The authors' paper may still be correct, but a quote inlined in the text, can fail sooner. The more the number of inlined quotes, the higher the probability of failure. The authors and readers would be better served by sumarizing each view, and referencing, providing credit where credit is due, and citations.
On the other hand, some say that quoting the words of another is good because it makes science more humane, more fragile, more context-dependent, more understandable. Others think that it mostly shows the futility of quoting in science, where previous views are treated as immobile scientific truths, whereas they should be considered in history terms only, not providing a scientific guidance of what would be truth necessarily. In science [1,2], YES means NOT YET FALSE, and NO means MAYBE TRUE. The ground shifts.

Eddington  was one of the few who tried to answer the above question, for the case of the decomposition of white light by a prism; however, his answer is ambiguous. Burgers  reportedly (see Ref.) reportedly also refers to this case, but his interest lies in the phenomenon of turbulence, where Fourier analysis and other methods of decomposition are employed. Also, Hinze , just before mentioning the Burgers paper, says: "... Though a harmonic analysis of the velocity fluctuations [in a turbulent fluid] can be carried out, this fact is no proof that, conversely, the turbulent fuctuations are composed of these harmonics. Compare the similar problem in the case of sound, where one may distinguish between noise (turbulent) and note (composed of a number of harmonics)."
This problem could conceivably appesr in every domain of physics. Is there an unambiguous abnswer to Eddington's dilemma: "discovery or manufacture?"

The genetic information of retrovirus integrates into a host cell's DNA, which results in viral replication. The only solution is to attack the virus in order to get rid of HIV. Below is an attachment of how Biotechnology, Mathematics, Bio-process engineering and physical sciences can work together to find a solution.
Most of the great ideas in philosophy, math, science and engineering were done with simple pen and pencil. Great thinkers such as, Pythagoras of Samos Leonardo di ser Piero da Vinci, Newton, Edison, Charles Darwin, and others have created their great works with contemporary technology. The technology today is much more advanced and sophisticated with so many tools and functionalities, and yet still quite simple and limited, compare to technology of tomorrow. Will the future much more sophisticated and smart technology of tomorrow contribute to creation of greater ideas and works of philosophy, arts, math, physics, science and engineering tomorrow.
I think we have clearly entered the time of the anthropocene. Does that change the way we should teach physics and sciences? Or is it just again about good science teaching, but with a specific content?
- Science is an oversimplification or a simple explanation for a seemingly complex observed phenomenon--this is a universal definition applicable to all branches of science.
- Science is not a simple accretion of facts or data and their manipulation through statistics.
- While physical sciences (Physics, Chemistry and other branches, and their mathematical realms) remain theoretically far ahead of what is practically possible (see attachment), medicine lags far behind in rock-solid theory and tries to make that up with experiments in animals and humans and of course, through genetics -- the cart-before-the-horse approach. More so, medical researchers are surprised that their approaches to science might be called faulty or proven faulted.
- "Everything that can be counted does not necessarily count; everything that counts cannot necessarily be counted"-- Albert Einstein. There are instances where the immeasurable is more important than the measurable -- see attachment. Science, and particularly medical scientists, and most specifically migraine researchers have no clue about the immense depth and width and length of the immeasurable dimension.
- Straight quote from my book (see attachment): "Migraine remains a classic example of a clinical entity that has not yielded its secrets to statistical legerdemain. Perhaps in no other clinical entity has the immeasurable proven so much more important than the measurable...The key cranial physiological system involved in migraine remains unidentified...Natural laws become apparent only when science becomes abstract, bordering on art...Whatever is statistically significant is certainly publishable; equally certainly, it is not biologically or medically original".
- "Obviously science follows no (man-made) plan. It develops at random. Its progress depends on fortuitous conditions, such as the birth of men of genius, the form of their mind, the direction taken by their curiosity...Men of science do not where they are going. They are guided by chance, by subtle reasoning, by a sort of clairvoyance...We have an almost irresistible tendency to select the subjects of our investigations for their technical facility and clearness rather than for their importance"-- Alexis Carrel, "Man, The Unknown",1959--Nobel Laureate.
- This scientific misery refuses to let up, except in a few pockets of excellence in medical research, that are there for us all to admire.
- The accountant mentality of medical researchers of the 20th and 21st century is also there for all to see in medical journals published worldwide. The reversal of the swing of the pendulum is imminent with the demise of the p-value no longer a distant mirage -- see attachments.

Convergence approach is viewed evermore as an approach to be adopted in scientific research. The life sciences, physical sciences, Engineering, culture & media studies seem to have made major advances with convergence approach. What need the social sciences to do to get out of their departmental ghettos and work in partnership with others? Produce research papers with co-authorship, or use citations from other areas in one's research? In historiography would be necessary to work more along the view of connected histories?
In the article linked below, there is a table listed tight binding hopping parameter obtained from DFT calculations, I want to know what method they used to get those results?
Thanks a lot!
By definition, a shape is an external form or appearance of something. This is how the Oxford English Dictionary defines the term shape. But then this definition raises more questions than it answers.
In his Essentials of Topology with Applications, CRC Press, 2010, Steven G. Krantz asks whether a ruler and a sheet of paper have the same shape, since both are rectangles.
We might also ask the following related questions.
Does a donut have the same shape as a wedding ring, since each one has a hole in its center?
For that matter, do all objects with a single hole in their centers have the same shape?
Is the concept of hole part of the concept of shape? In other words, do we need to take into account the presence or absence of holes in every shape?
There are many different types of shapes in Physical Science. For example, a Wulff shape is an an equilibrium minimal surface for a crystal or drop which has the least anisotropic surface free energy for a given volume. Wulff shape are explained in
The theory of shape is a central topic in Mathematics. For example, Karol Borsuk introduced the theory of shape in his 1970 lectures:
For Borsuk, shape theory is the focus of geometric topology, which is a study of the topological properties of metrizable spaces.
Shape theory is also closely related to what are known as retracts.
Long before the study of shapes entered into the picture in the Physical Sciences and in Mathematics, shapes were the focus of the Fine Arts (painting and sculpture) and Philosophy. Capturing shapes is a central activity in painting. A classical example is the chiaroscuro effect using various forms of highlighting objects:
And shapes were (and still are) of great interest in Philosophy, The classical example an interest in external forms can be found in the works of Plato and Artistotle.
What we mean by shape? is an open question. A related open question concerns similar shapes. When do objects have similar shapes?
I am currently writing up my PhD which is a mixed method evaluation of a workplace intervention. I am writing up as one study and would welcome the opportunity to read other people's PhD thesis that have done a similar thing.
Is there anything similar to parametric down conversion in NMR?
(I know, NMR is an ensemble QC. But, how can I entangle a qutrit or qudit using it?)
Hello, every friend!
I need to calculate the optical potential between two nuclei, so I've tried to find open source folding potential calculation codes.
I have known that there are DFPOT and SPI-GENOA, but I haven't found their codes that can be used directly, i.e., where to download them?
Thank you very much!
I use what I call the "historical-investigative" method, which focuses on presenting scientific concepts as in the process of their discovery. The main vehicle for this is "rediscovering" these concepts while repeating historical experiments. See examples of how it is presented to teachers in the files attached.
This question can be broadened to the most of the physical sciences and mathematics, but I'm mostly interested in chemistry concepts like 'bonding' and 'structure.' At which age can a particular concept be assimilated? I'm not an education theorist; please feel free to suggest appropriate background reading. I'm expecting the answer is contextualized on the dominant educational approach for a given culture.
Electron bubble (an electron/ positron occupying a self created spherical cavity in liquid Helium-4 or Helium-3) is an interesting real physical system which closely represents a quantum particle trapped in a spherical cavity. I am interested to know other such systems. I would appreciate your help in providing such examples.
