The requirement for degrees persists for several reasons, despite the growing emphasis on skill sets:

• Standardization: Degrees provide a standardized measure of education, ensuring a baseline level of knowledge and competence.
  
• Credentialing: Degrees serve as formal credentials that are widely recognized and respected by employees, indicating a certain level of expertise and commitment.
  
• Structured Learning: Degree programs offer a structured learning path, covering both foundational as well as advanced topics systematically.
  
• Comprehensive Education: Degrees encompass a wide range of subjects which are essential for all-round development.
  
• Networking: Colleges and universities offer networking opportunities, connecting students with peers, professors,alumni and industry professionals.
  
• Research and Development: Higher education institutions often provide access to research opportunities, fostering innovation and advanced study.
  
• Employer Preferences: Employers often prefer or require degrees as they simplify the recruitment process and serve as a reliable indicator of a candidate’s abilities.

Even though developing important skills is essential, degrees remain important for offering a well-rounded education, official qualifications, and chances to build connections. Achieving a balance between obtaining degrees and honing skills can provide a combination of benefits.

Srinivasa Ramanujan made profound and significant contributions to the mathematics, including:

• Number Theory
  1. Partition Function: Created approximate formulas for partition functions and unearthed Ramanujan’s tau function.
  2. Ramanujan Prime: Defined Ramanujan primes and provided characteristics regarding prime numbers.
  3. Studied and explored highly composite numbers.
• Infinite Series
  1. Ramanujan Summation: Devised techniques for assigning finite values to infinite series that do not converge.
  2. Have made important advancements in the field of q-series and continued fractions.
• Modular Forms
  1. Mock Theta Functions were found, leading to the advancement of the theory of modular forms.
  2. Explored modular equations and transformations.
• Elliptic Functions: Played a key role in the development of elliptic functions and their associated areas.
• Mathematical Analysis
  • Discovered and demonstrated the Rogers-Ramanujan identities.
  • The Master Theorem by Ramanujan: Offered a useful technique for calculating definite integrals and infinite series.
• Advanced in the field of continued fractions, offering fresh findings and perspectives.

Ramanujan’s deep understanding of mathematics, along with his many innovative findings and speculations, some of which were not even proven by modern scientists for some years has had a long-lasting effect, impacting different fields (like String Theory by Stephen Hawkings used the infinite number series of Ramanujan) and motivating further studies.

Detecting signs of life on exoplanets beyond our solar system is a complex task. Some methods include:

1. Biosignatures in Atmospheres:
   We study exoplanet atmospheres for specific gases (by transit spectroscopy, etc) that could indicate life.
   • Oxygen (O₂): Oxygen is produced by photosynthetic organisms. Detecting abundant oxygen could suggest biological activity.
   • Methane (CH₄): Methane can be produced by microbes or geological processes. Nitrous Oxide (N₂O) is used in microbial activity.
   • Water Vapor (H₂O) and Carbon Dioxide (CO₂) are essential for life and photosynthesis.
2. Fluorescence and Reflectance:
   Some organisms exhibit fluorescence when exposed to UV light. Detecting such fluorescence from an exoplanet could be a sign of life. Analyzing the reflected light spectrum can reveal unique signatures related to pigments or biological processes.
3. Temporal Variations:
   Seasonal changes or irregular patterns in light (due to vegetation growth, ocean currents, etc.) might indicate life cycles.
4. Technosignatures:
   We look for artificial signals (techno-signatures) like radio waves, laser emissions, or megastructures (e.g., Dyson spheres).

Obstacles:

• Distance: Exoplanets are located at a distance of light-years, which makes it challenging to conduct detailed observations.
• False alarms: Non-biological activities can imitate signs of life.
• Current telescopes do not have enough sensitivity to definitively detect what is needed.

India’s reservation system, established to address historical caste-based discrimination, has both positive and negative effects on academic quality and social mobility:

Academic Quality:

• Positive: The system promotes diversity by admitting students from marginalized backgrounds, enriching the learning environment.
• Challenges: Critics argue that lower entrance exam scores for reserved category students may compromise academic standards.
• Mitigation: Institutions must focus on improving teaching quality and infrastructure for all students.

Social Mobility:

• Positive: Reservations empower disadvantaged communities, breaking the cycle of poverty and promoting upward mobility.
• Challenges: Some view reservations as perpetuating caste identities and hindering merit-based selection.

Comparisons:

• India vs. USA: Similar to affirmative action policies in the US, both aim to increase diversity and inclusion. However, the Indian system is more rigid with quotas, while affirmative action considers various factors beyond race or caste. India’s reservations are constitutional mandates, while US policies vary by state and institution.
• Meritocracy Debate: India’s system emphasizes social justice, while the US debate centers on balancing meritocracy and equity.

In summary, India’s reservation system balances access, quality, and social justice. Comparing it to affirmative action elsewhere highlights diverse approaches to addressing historical inequalities.
