Father & Son

#Antony and Son

AK Antony's statement calling for the defeat of his son, Anil Antony, the BJP candidate in Pathanamthitta, is indeed bold but unexpected. While on the surface, Antony's stance may seem admirable it raises questions about the underlying dynamics within his own party and family. This public disapproval could indicate internal strife  within his family.

 Antony's statement challenges traditional notions of familial loyalty and dynastic politics prevalent in Indian politics. In a society where family connections often play a crucial role in political advancement, Antony's stance could be seen as a departure from the norm.. It highlights the complexities of familial relationships in the political arena.

Seemingly, the "Krupasanam Amma" rejected the request of Elizabeth, Antony's wife, who pleaded good prospects for her son. Antony and his son are not a role model for all fathers and sons in Kerala.

Upholding Mohiniyattom

#Upholding #Mohiniyattom.

Kalamandalam Sathyabhama's courageous stance on the essential elements of Mohiniyattom dance competitions should be commended, She emphasizes the significance of talent and skill over superficial attributes created by make-up. Her dedication to upholding the integrity of the art form deserves respect, as she fearlessly speaks out against the prevalent biases that prioritize appearance over talent. 

It's imperative to recognize and support artists like Sathyabhama who advocate for the true essence of their craft, rather than succumbing to societal pressures that undermine its authenticity. The backlash and insults directed at Sathyabhama on social media are not only unjust but also indicative of a broader issue within the artistic community. 

Rather than engaging in constructive dialogue  resorting to threats and humiliation only serves to stifle creativity. It discourages artists from speaking  truth. The notion that a male artist is inherently unfit to perform the role of Mohini in Mohiniyattom is not a regressive belief. Though Art transcends gender boundaries, and talent knows no gender a man dancing as Mohini would not get that much appeal

.Sathyabhama's advocacy for merit-based evaluation  should be celebrated as a step towards creating a more equitable artistic community. Her question, whether the authorities can delete the mark column for artist's beauty for Mohiniyattam in art fairs, is relevant..

Feast tussle

#Feast #tussle

Governor attending or not, Chief Minister Pinarayi Vijayan not inviting Governor Arif Mohammed Khan to the Christmas party he is hosting is an unhealthy practice

It is to be remembered that

earlier, the governor had invited the CM and other ministers to his Christmas party at Raj Bhavan on December 14. But they declined the invitation amid the tussle with the governor over various issues.

Parties are often held as part of building a strong cultural belief and friendship. Such celebrations bring people together and develop respect and understanding. The current imbroglio of the feast shows that the head of state does not need friendship with the head of government. Poor are the chief minister's advisers.

Fans clash

#Fans #clash

It was reported that the Footbal World Cup celebration turned violent in various parts of the state. In Kochi and Thiruvananthapuram, fans even attacked police officers and in Kannur, a fight between various groups of fans left three injured. Additionally, DYFI and AIYF activists clashed in Kottarakara.

This kind of clash between supporters is mainly caused by their emotional bonds as they feel the need to defend what they support, and this happens more often in football. In football, the average duration of a match is 90 minutes, which causes fans to experience different types of emotional outbursts. And this is compounded by overconsumption of alcohol and drug use. The only remedy is to let the fans fight each other and waste their chergy.

However, if innocent people are attacked, it will be dealt with with an iron fist. Less trouble in countries with footballers and more trouble in countries where no internationally renowned player is present, it's quite incomprehensible.

Particle nature

This equation is often taken to mean that matter and energy are two sides of the same coin. . . . 

One of the simplest examples of this is electron-positron annihilation. " 

CREATING MATTER FROM LIGHT

If you can convert matter entirely into energy, you should be able to do the reverse. It’s known as the Breit–Wheeler process and involves colliding two photons to create an electron-positron pair.

In 1905, Einstein wrote a paper that was changed Particle Physics forever.

Einstein,  E = mc^2

In 1927, Dirac clarified Einstein’s idea as dualistic particle: E=±MC²      

 (matter – antimatter are two sides of the same coin)

Madam Wu

Chien-Shiung Wu (May 31, 1912 – February 16, 1997) was a Chinese-American experimental physicist who made significant contributions in the field of nuclear physics. Wu worked on the Manhattan Project, where she helped develop the process for separating uranium into uranium-235 and uranium-238 isotopes by gaseous diffusion.

She is best known for conducting the Wu experiment, which proved that parity is not conserved. This discovery resulted in her colleagues Tsung-Dao Lee and Chen-Ning Yang winning the 1957 Nobel Prize in Physics, while Wu herself was awarded the inaugural Wolf Prize in Physics in 1978. Her expertise in experimental physics evoked comparisons to Marie Curie. Her nicknames include the "First Lady of Physics", the "Chinese Madame Curie" and the "Queen of Nuclear Research".

Higgs boson.

The biggest news in particle physics is no news. In March, one of the most important conferences in the field, Rencontres de Moriond, took place. It is an annual meeting at which experimental collaborations present preliminary results. But the recent data from the Large Hadron Collider (LHC), currently the world’s largest particle collider, has not revealed anything new.

Forty years ago, particle physicists thought themselves close to a final theory for the structure of matter. At that time, they formulated the Standard Model of particle physics to describe the elementary constituents of matter and their interactions. After that, they searched for the predicted, but still missing, particles of the Standard Model. In 2012, they confirmed the last missing particle, the Higgs boson.

How nature works

Sometimes, if you want to understand how nature truly works, you need to break things down to the simplest levels imaginable. The macroscopic world is composed of particles that are — if you divide them until they can be divided no more — fundamental. They experience forces that are determined by the exchange of additional particles (or the curvature of spacetime, for gravity), and react to the presence of objects around them.
