Retraction of Scientific Articles in India
I read with great interest a news article published in Nature on rising retractions in India (1). Though India doesn't boast of any university or IITs in top 100 list of globally reputed rankings like Times Higher Education, QS etc; it has seen a steady rise of research papers from what we had in 2001. However India's research papers are not cited heavily and there is an overall doubt about the quality (2). No wonder the retraction rate is high. Most of the Indian institutes don’t punish the scientists with retracted papers. I personally know one or two scientists in my circle who have carried on unfettered despite having had several of their papers retracted. Now, Indian researchers are under immense pressure to perform because in most of the places incentive of publication is promotion or increments. Recently India has seen an unprecedented rise in the Private Universities and Colleges whose sole motto is increasing student enrolment and vying for the prized global or national rankings (3). Professors literally perish if they don’t publish; they are given targets to publish and incentives like the salesmen or the corporate. Obviously with so much under stake the numbers of publications will continue to swell with increased retractions, unchecked growth and no real-world impact.
At least 25 papers of one scientist from Saveetha University, Chennai has been retracted in July 2025 (4). This particular Chennai based university is under radar for maximum retractions in the past 4 years with 99,80 and 90 retractions in 2023,2024 and 2025 (5). One Physics professor of IIT Dhanbad has had 34 retractions since 2018, yet he got promoted to Associate Professor recently (6). UGC, the regulator of all Indian Universities and the apex body, a decade ago had prepared a list named UGC CARE list in line with the Beale list to prevent predatory journals and paper mills. However, very recently UGC scrapped its own CARE list creating more confusion, utter dismay and sparking fears about unscrupulous paper mills (7).
Overall, as India is gearing up for burgeoning private education paraphernalia with ever increasing appetite for quantity over quality of research papers and a pressure to perform, it doesn’t appear that retractions are going to stop soon.

Asia's contribution to Quantum Mechanics on its centenary
I read with great interest the editorial (1) and essay (2) on celebration of the centenary of quantum mechanics. I was particularly happy about the mention of Lucy Mensing, a woman scientist who contributed to quantum mechanics.
However the focus on the development of the subject of quantum mechanics was shown to be mainly Euro Centric. Though it is true and many American scientists like Oppenheimer indeed congregated in Europe to study the new science of quantum mechanics, there were two major centres outside Europe which played a crucial role in the development of the theory of Quantum Mechanics. Self-taught Physicists from Calcutta, India and Osaka, Japan, independent of the European stalwarts developed theories in Quantum Mechanics which became part of the subject matter and its history. For example, Satyendra Nath Bose trained in Calcutta University and while working as a young professor in Dacca, now called Dhaka, developed Bose - Einstein Statistics (3). This statistical model had a far reaching impact in categorising sub atomic particles as Bosons and in Bose Einstein Condensate research. Though many Nobel laureates owe their award to Bose Einstein Condensate and Bosons, S.N.Bose himself never got a Nobel. Also, trained in Cambridge, another Indian nuclear physicist, Homi J Bhabha used quantum mechanics to explain the cascade showers in cosmic rays.
Similarly, Hideki Yukawa of Osaka University combined quantum mechanics with nuclear forces to predict Meson, a subatomic particle. Yukawa Potential results from an analogy of quantum field theory. When Mu Meson and Pi Meson were proved to exist by experimental physicists in 1936 and in 1947, Yukawa was awarded a Nobel prize in 1949 (4). Bhabha and Yukawa attended the immensely eminent Solvay Conference of Physics with master proponents of Quantum Mechanics.
So, it appears that outside Europe there were Asian centres of excellence where quantum mechanics theory was developed without training from Europe. Very often, these Asian masters are overlooked however it must not be forgotten that S.N.Bose and Yukawa were homegrown talents who played a crucial role in the development of quantum mechanics in the very beginning. Both of them later on went to Europe and the USA for further work; however their formative years when they formulated their contributions were totally independent of the then European stalwarts.

Need for more Psychological Counsellors and First aid in mental disease
The way we are behaving is increasing the rate of mental illness day by day. The stress, the relationship issues, the constant hook up and break up culture, financial distress all are adding up to our constant misery. Modern life is no longer easy. We pay the price of living by depression and anxiety.
India has now >15% population suffering from mental illness. However help is scanty with less doctors and counsellors available mostly in urban set up. I feel, instead of making too many engineers ( IT Jobs are the most attractive) we have to start making more psychiatrist and counsellors. The days are coming where common mental disorders like depression and anxiety will become as regular as Common Cold. There is so much to tell but nobody to listen. Tele counseling services are overflooded with suicidal calls. In India where mobile internet penetration is very high we should now add more tele counselors to save the distressed souls. Already like weight reduction apps India started Tele Manas, Mindpeers, Rocket Health etc for Counseling. Tele Manas the GOI initiative is spreading its network to different states in India.
https://telemanas.mohfw.gov.in/home
Click to get help
If you can pay by GPay and Phone Pe then you should be able to unburden your chest by a phone call. IT jobs are always popular, but next big lucrative jobs will be in Psychological health ( Mental Health Care). With every passing year, being a teacher I see many students crying for help. Since I am safe, non judgmental and highly approachable, most students favor to call upon me; however I am ill equipped to treat them. Hence I channelize them to campus doctor and counselors.
We are short of mental health care staff in our country and it is urgent that many more personnel should be trained in counseling and psychiatry. Next big lucrative career will be Psychology professionals because robots and AI cannot touch the soul of a human being. Common mental disorders will be the next pandemic unseen but known to all and with no help nearby the patients will feel helpless, frustrated. Even if they forget the stigma there will be no one to approach because of shortage of trained mental health care professionals.
In this regard I suggest a book " Where there is no Psychiatrist" by Dr Vikram Patel which can be a First aid for mental health. The link is given, free to download.
https://asksource.info/pdf/30256_wherethereisnopsych_ch1_2003.pdf
I also think it is time to increase enrolling of psychological counselors.
Hope is eternal and things will change.

Western Classical Music, Death and Funeral
Actually Mozart was very afraid of death. He died quite young and during his last days he was commissioned by a Count in Vienna to write a Requiem which he did with a dark assumption that the messenger of the Count is a harbinger of his death which was near. Listen to Mozart's Requiem
Then Beethoven courted death when he was turning deaf. Music was everything to him and how frustrating it must have been for him to discover at the prime of his musical career that he is losing the sense of hearing. A musician turning deaf is like a surgeon who cannot hold a scalpel because his hands tremor or like an orator who cannot speak ! Beethoven thought of suicide and wrote a will which is famously known as Heligenstadt testament ..
.http://en.wikipedia.org/wiki/Heiligenstadt_Testament ...
he actually changed his mind after a visit to a countryside and celebrated by writing the Sixth symphony which I believe is his best. A movie on Beethvoen called Immortal Beloved
Rossini, Bach and Handel also wrote several mass to be performed during burial ceremony in church.

Payment for Journal Reviewers
I have also observed the reviewers are slow to act; they send their opinions across after prodding and pleading. Every editor knows how difficult it is to make the reviewers submit their comments in time. Sometimes it takes months. Their reluctance to review for a journal is not caused by professional ineptitude but by lack of payment. If the journals are taking money for publication then the editors can pay, whatever small the amount may be, to the reviewers. Silver tonic always works in getting things done. Money can be an incentive for the reviewers and the reluctance and lethargy to review can go. This can also be a pathway to generate more income by the reviewers (2,3). The process of review actually takes a long time now and mars the spirit of the scientists who submitted their articles for review. I suggest the journal editors think of paying their reviewers for speedy publication (3). Many scientists prefer a journal for faster publication process. As you increase the speed of publication, the journal profits by attracting more authors and revenue generation in the end.

Music Education: Chamber Music
Chamber Music
Chamber music is music
written for small combinations of instruments, expressing intimate and personal
emotions. Originally it was meant to be performed inside a room with friends
and not in the concert hall. From the room or chamber this music gets its name
Chamber Music. Almost all the composers have written beautiful music in this
form. But the best chamber music has come from Bach, Handel, Haydn, Mozart,
Beethoven, Schubert and Brahms. Chamber music starts with the combination of
two instruments, a "duo" as it is called and goes right up to nine
instruments or "Nonet". More than nine instruments become music for
small orchestra or chamber orchestra. For these small orchestras the composers
have also written works and these are known as sinfonias, or sinfonettas, or
concertinas, in other words small symphonies and concertos.
Given below are the
different categories of chamber music.
The Duo :
This can be in various combinations, two violins, violin and piano, piano and
oboe, piano and clarinet,
piano and flute, piano and horn. The most common is the violin and piano
combination and in this, the works of Mozart and Beethoven are the momentous.
The Trio Sonata:
This is virtually a duo because the third instrument merely holds on to the
note like the Indian Tanpura. Bach and Handel wrote a lot of Trio Sonatas. The
form really existed in the Baroque Age (1600-1740).
The Trio: Very popular
chamber music form. The most Popular combination is violin, piano and cello.
There are other combinations, violin, viola and cello (known as string trio).
Beethoven wrote some wonderful string trios. Then there is clarinet trio or clarinet,
cello and violin in which combination Mozart wrote and so did Brahms. but the
most famous trios are the piano trios of Mozart, Haydn, Beethoven, Schubert and
Brahms. Dvorak's "Dumky" trio is also a lovely work;
The Quartet: most important is the string quartet
in which some of the greatest music of the composers have been written. This
consists of two violins, viola and cello. The string quartets of Haydn, Mozart,
Beethoven and Schubert arc the most important. The string quartet like the symphony
can be called the backbone of western classical music. By dropping one
instrument of the string quartet usually the second violin and adding either
piano, horn or clarinet, the composers have obtained unique patterns of sound.
The two piano quartets of Mozart, written for piano, violin, viola and cello,
are very great works. Brahms wrote three piano quartets and so did Beethoven
and Dvorak. Mozart also wrote flute quartets and oboe quartets and also a horn
quartet where a fourth instrument outside the string family is added onto a
string trio.
Quintet:
The addition of a fifth instrument either a viola in case of Mozart and cello
in case of Schubert creates the form of
the string quintet. Mozart's string quintets are great works and so is the
string quintet of Schubert. If the fifth instrument is a piano it is known as a
piano quintet as in the case of Schubert's popular Trout Quintet. Schumann, Brahms
and Dvorak wrote piano quintets. Mozart and Beethoven also wrote a quintet for
a combination of a wind quartet, that is clarinet, oboe, bassoon and horn and
the piano as the fifth instrument. The piano and wind quintets of Mozart and
Beethoven are utterly ravishing works. Mozart, Brahms and Weber also wrote
clarinet quintets, where the clarinet takes the place of the piano.
Sextet:
The addition of two more instruments to the string quartet makes it a sextet.
Brahms wrote two beautiful string sextets. He also wrote string quintets like
Mozart. Mendelssohn and Dvorak also wrote string sextets.
Septet:
A combination of seven instruments makes it a Septet. The most famous work in
this category is the Septet by Beethoven. It is a product of Beethoven’s youth
full of passion and feeling.
Octet:
A combination of eight instruments, strings and winds makes it an Octet.
Schubert wrote a famous Octet for winds and strings while Mendelssohn wrote an
Octet only for strings Both are captivating works.
Nonet:
Nine instruments is a rare combination and only some contemporaries of
Beethoven like Spohr used it. Chamber music ends with the Nonet. After that it
becomes orchestra.
Practical reasons made
composers write for small groups for it was not always possible to get a large
orchestra. Sinfonias and Sinfonettas could be also performed easily. One can mention
Mozart's serenade for thirteen wind instruments, a masterwork that remains
unsurpassed in charm and beauty. Most of Mozart's divertimentos and serenades,
which contain some of his most vivacious music is written for a small orchestra
of ten to fifteen players.
Chamber music is the key
to feeling the pulse of the composers. The greater the composer the better his
chamber music output.

Music Education: Sonata
Sonata
Sonata refers to a particular structure or
form of music in which composers have written works ever since the 16th
century. A sonata can be for solo instruments like the piano or a combination
of two instruments like the piano and violin, piano and clarinet, piano and
cello, piano and horn etc. There is another type of sonata for three
instruments known as Trio Sonata which used to be popular in the 16th
and 17th centuries in which two of the instruments really played the
major role and the third held
the tune rather like the Indian tanpura or drone instrument. Sonatas are
usually in three movements but there is no fixed rule. The first movement is constructed with two melodies rather
like the first movement of the symphony. A simple formula will help to understand
this construction. Suppose we call the two melodies A and B, A being strong
and masculine, B being soft and
feminine. How are they presented? The first part of the movement belongs to A then B is introduced and combined
with A almost like a marriage and
then out of the blending or the marriage of these two melodies a third melody or
C emerges as the conclusion of the
movement. Therefore we can map the flow of this movement with the following
equation,
A B ABBA C
Where A refers to the
first melody B
to the second melody ABBA to the blending of the two and
C to the conclusion. In some sonatas there is an introduction before A, which
appears rather like the opening of a door and we can call this section D. The
first movement of the symphony and the concerto is based on this formula. So if
you are good in catching tunes you should be able to follow these forms of
music and have fun and enjoy yourself. Mozart, Beethoven, Schubert, Schumann
and Brahms all wrote beautiful Sonatas.

Music Education : Symphony
The Symphony
The most famous of all musical forms. It means an
orchestral composition in four sections with distinct pauses in between
sections. The four sections are called movements. But there are symphonies with
more or less than the standard four movements. The first movement is usually
the most important movement of a symphony and it sets the mood of the whole
symphony. It usually deals with two melodies or themes as they are called,
which are displayed, developed and brought to a conclusion. The first movement
is usually fast paced, magnificent and noble. The second movement is in
contrast, lyrical, personal, meditative and slow moving. It is intimate in
mood. The third movement is a dance and full of vivid motion. This dance
movement has two melodies, one stated by the full orchestra and the other by a
few instruments grouped together. The constant contrast that these two melodies
produce is the charm of this movement. The last movement or finale is a
blazing, triumphant fast paced piece of music of epical grandeur. The symphonic
message is the triumph of the human will over tragedy and the infinite
possibilities of human endeavor. Though there are symphonies that end
tragically in a slow piece of music, most symphonies conclude with a blazing
panorama of sound.
The great symphonies are the symphonies of Haydn,
Mozart, Beethoven, Schubert, Schumann, Mendelssohn, Brahms, Bruckner, Mahler,
Sibelius, Dvorak and Tchaikovsky. If you can listen to some symphonies of these
composers you will get a good idea of the sound of the symphony. Symphony has
become part of the English language and it means a richly blended outpouring of
different strands of sound. The word symphonic suggests grand scale and size.
Musically it means just that, a large scale work of tremendous passion and
grandeur.
I have provided a list of 10 important symphonies
below. Click on the link, you will be followed to Youtube. Track the movements
and their pace each time you listen one. Sometimes the movements and their
lengths are written below the Youtube title in the description section. For
example, if you pick up Beethoven 3rd Symphony you will find 4
movements;
0:20
I. Allegro con brio
16:13
II. Marcia funebre: Adagio assai
32:02
III. Scherzo: Allegro vivace
37:57 IV. Finale: Allegro molto
Here, time of each movement is mentioned in HH:MM (
hour:minute) format. The term Allegro means Fast pace and Adagio means slow
pace. Vivace means lively.
Likewise you can read a description of movements of
each symphony from Youtube or Internet to learn the separate pace and mood of
movements. About naming some symphonies as Eroica or Farewell or Unfinished, I
shall share anecdotes in a separate post.
