CAPTCHA
- CAPTCHA Definition: Completely Automated Public Turing test to tell Computers and Humans Apart. It is a security measure to distinguish between human users and bots.
- Purpose: Protect websites from automated attacks like spam, fake accounts, and data theft.
- Origin: Introduced in the early 2000s due to increasing bot activity. The first patent was filed in 2003 by Luis von Ahn and his team.
- How it works: Presents challenges that are easy for humans but difficult for computers, such as identifying distorted text or specific objects in images. Based on the Turing Test.
- Evolution: Started with distorted text, evolved to include image recognition, audio challenges, and behavioral analysis (e.g., mouse movements with “Invisible reCAPTCHA”). reCAPTCHA was introduced in 2009 to digitise printed text.
- Applications: Used in website forms, comment sections, registration pages, financial transactions, account recovery, and online surveys.
- Limitations: Can be bypassed by increasingly sophisticated bots. Presents accessibility challenges for users with disabilities. Can be annoying and time-consuming for users.
- Future: Needs to become more accessible and user-friendly while remaining effective against evolving bot technology.
Mahabodhi
- Protests for BTA Repeal: Buddhist monks under the All India Buddhist Forum (AIBF) are protesting at the Mahabodhi Temple demanding the repeal of the Bodh Gaya Temple Act (BTA), 1949. The Act establishes a management committee for the temple with equal Hindu and Buddhist representation.
- Grievance: Buddhist bodies want full control over the Mahabodhi Temple (Mahavihara).
- BTA Provisions: The BTA created an eight-member management committee with equal representation from Hindus and Buddhists. The district magistrate, traditionally a Hindu, is the ex-officio chairperson, leading to a perceived Hindu majority in the committee.
- Historical Context: Emperor Ashoka built the Mahabodhi Temple in the 3rd century BCE. It remained a Buddhist site until the 13th century, when Buddhism declined. In 1590, a Hindu monk established a mutt, bringing the temple under Hindu control. The BTA (1949) aimed to resolve the dispute between Buddhist and Hindu heads but the fact that the DM was an ex-officio chairman and traditionally from the Hindu community was a source of contention.
- Past Protests: Protests and memorandums have been submitted in the past, including a Supreme Court writ petition in 2012 that is yet to be heard.
- Government Intervention: In 2013, the rule was amended to allow the ex-officio chairman to be of any faith. In the early 1990s, there was an attempt to pass the Bodh Gaya Mahvihara Bill that would give control to the Buddhist community, but it went into cold storage.
TopoMat
-
Topological materials are a new class of quantum matter exhibiting unique properties: conducting electricity on their surface like a metal but insulating internally like glass.
-
Discovery & Recognition: Discovered in the late 20th century, groundbreaking work in this field was recognized with the 2016 Nobel Prize in Physics.
-
How They Work: This behavior stems from quantum mechanics, particularly the topology of electronic band structures and spin-orbit coupling. Electrons behave differently on the surface (free-moving) versus the inside (localized).
-
Mirror Analogy: A mirror, composed of a glass front (insulator) and a metallic back (conductor), helps illustrate this duality.
-
Quantum Foundation: Understanding topological materials requires quantum mechanics. The UN declared 2025 as the International Year of Quantum Science and Technology.
-
Significance: These materials hold potential for next-generation electronics, quantum computing, and low-power devices. An example of a chip made from topological material is already released by Microsoft.
-
Electron Behavior: In metals, electrons are free (“unruly”) forming a “soup” that conducts electricity and reflects light. In insulators, electrons are bound (“shy”), preventing conduction and allowing light to pass through. The behavior decides how light interacts with the materials.

Governor’s Bill Power
- SC Verdict: Governors must act on state bills in a timely manner, adhering to the advice of the council of ministers (Article 200), without undue independent discretion.
- Tamil Nadu Case: Governor’s delay in assenting to 10 bills and subsequent referral to the President after re-enactment by the Assembly was deemed “erroneous in law” by the SC.
- No “Absolute Veto”: The SC clarified that Governors do not possess an “absolute veto” or “pocket veto” under Article 200, preventing indefinite delays.
- Timelines Prescribed: The SC set timelines for Governors: one month to withhold assent, three months if acting against State Cabinet advice, and one month for re-presented Bills.
- Governor’s Role: Emphasized as a constitutional head, not a political actor, bound to act with deference to parliamentary democracy and the will of the people. Must act as a “catalyst and not an inhibitor”.
- Limited Discretion: Governor can only refuse assent to a bill when a bill is different and Governor’s discretion is subject to judicial review.
- Implications: Curbs misuse of gubernatorial powers, reinforces the legislative process, and sets a precedent for states facing similar issues (Kerala, West Bengal, Telangana, Punjab).
- Article 142: Exercising powers under Article 142 of the Constitution, the bench also declared the 10 Bills as having received assent given “the unduly long period of time for which these Bills were kept pending by the Governor before the ultimate declaration of withholding of assent and in view of the scant respect shown by the Governor”.
- Kerala’s Plea: Kerala government requested its similar case against its Governor be transferred to Justice Pardiwala’s court, given the ruling’s relevance.
