  • The Physics of Thermometers, Temperature and Cold Atoms

    Why in the News?

    An article in The Hindu explained the scientific principles behind thermometers, temperature scales, absolute zero, and ultra-cold atomic physics, highlighting how measurement of temperature evolved from mercury thermometers to quantum physics-based studies of cold atoms.

    What is Temperature?

    • Temperature is a measure of the average kinetic energy of atoms and molecules in a substance.
    • When heat is supplied:
      • Atoms and molecules move faster.
    • When heat is removed:
      • Their motion slows down.
    • Thus, temperature reflects the degree of atomic agitation inside matter.

    Celsius Scale

    • Developed by: Anders Celsius

    Basis of the Scale

    • 0°C: Freezing point of water
    • 100°C: Boiling point of water
    • The interval between these two points is divided into 100 equal parts.

    Mercury Thermometers

    Why Mercury is Used

    • Uniform expansion on heating
    • Easily visible liquid metal
    • Good thermal conductor

    Digital Thermometers

    • Modern digital thermometers use Semiconductor materials
    • Principle
      • Semiconductors conduct limited electricity.
      • Higher temperature releases more free electrons.
      • Increased electric current is measured electronically and converted into temperature readings.

  • Google’s new ‘information agents’ are a privacy and web infrastructure problem

    Why in the News?

    Google recently introduced “information agents,” AI assistants capable of continuously monitoring the web on behalf of users. These agents aim to automate information gathering, recommendations, and decision-making by integrating data across Google’s ecosystem such as Search, Gmail, Maps, Chrome, YouTube, Android, and Calendar. 

    What are Information Agents?

    Google Information Agents are AI-powered assistants, announced at Google I/O 2026, designed to run continuously in the background of Google Search to monitor the web, synthesize information, and act on your behalf 24/7. They act as an evolution of Google Alerts, proactively providing updates on topics like apartment hunting or price tracking.

    Key Features & Capabilities

    1. Proactive Monitoring: Instead of waiting for a manual query, agents constantly check the web for updates tailored to specific goals.
    2. Synthesis & Action: Agents gather data from multiple sources, provide insights, and can trigger actions (e.g., booking, alerting).
    3. “AI Mode” in Search: Activated within the Google App, where users can set up and track these agents.
    4. Personalization: Agents use user-provided details (budget, location, preferences) to provide personalized, actionable results.

    Why Do Google’s Information Agents Represent a Structural Shift in the Nature of Internet Use?

    1. Passive-to-Autonomous Transition: Traditional search depends on active human input where users consciously search for information. Information agents shift this model toward persistent AI monitoring that continuously scans the internet without repeated user intervention.
    2. Continuous Monitoring: Agents remain active over time rather than responding to one-time prompts. They monitor categories such as housing, travel, stocks, health, or shopping preferences.
    3. Cross-Ecosystem Integration: Google integrates information from Search, Gmail, Maps, Chrome, Calendar, YouTube, and Android, enabling deeper behavioural profiling than standalone AI assistants.
    4. Predictive Personalization: Agents function by collecting increasing amounts of personal data because improved recommendations depend on richer behavioural information.
    5. Machine-to-Machine Internet: The article highlights a structural change where digital interactions increasingly occur between automated systems instead of humans directly browsing websites.

    How Could Information Agents Intensify Data Privacy and Surveillance Concerns?

    1. Behavioural Profiling: Agents require intimate personal details to function effectively. A housing-monitoring request may reveal location preference, family size, budget, commuting constraints, timeline, and travel plans.
    2. Sensitive Data Accumulation: Users may unintentionally disclose religious beliefs, political preferences, sexual orientation, medical history, and financial behaviour, expanding risks of sensitive profiling.
    3. Indefinite Data Storage: Information collected for agentic services may remain stored for prolonged periods, increasing risks of misuse or surveillance.
    4. Data Concentration: Google already possesses vast datasets through existing platforms. Information agents deepen concentration by linking fragmented behavioural data into unified user profiles.
    5. Limited Regulatory Protection: Current frameworks remain underdeveloped regarding liability if AI agents influence financial or personal decisions that later harm users.

    Can AI Information Agents Overload the Internet’s Infrastructure?

    1. Bot Traffic Expansion: AI-driven internet activity is already increasing sharply.
    2. Striking Data: The article cites the Thales 2026 Bad Bot Report, which estimates bots account for 53% of global web traffic.
    3. Sharp Increase in Attacks: AI-driven bot attacks reportedly increased 15 times in 2025.
    4. Blocked Requests Surge: Daily blocked bot requests reportedly increased from 2 million to 25 million within a year.
    5. Exponential Crawling: A conventional Google search may trigger one crawl after a query. Information agents repeatedly scan websites, potentially generating hundreds of automated fetches daily per user.
    6. Infrastructure Burden: Millions of subscribers using persistent agents could impose enormous computational and bandwidth costs on websites.

    Example 

    1. Housing Listings: An agent monitoring apartment prices continuously would repeatedly crawl real-estate websites to detect changes.
    2. Stock Monitoring: Persistent stock monitoring may generate frequent automated queries throughout the day.

    How Could Information Agents Threaten the Economic Sustainability of the Open Web?

    1. Publisher Revenue Erosion: AI agents may summarize content directly instead of redirecting users to publisher websites, reducing click-through traffic.
    2. Server Cost Burden: Publishers would continue bearing infrastructure costs while AI systems scrape and synthesize content.
    3. Content Extraction Problem: Information harvesting without proportional traffic or revenue could weaken incentives for quality journalism.
    4. Potential Publisher Pushback: Websites may increasingly block Google crawlers or restrict access to AI scraping.
    5. Negative Feedback Loop: Reduced publisher incentives may degrade content quality, weakening the informational ecosystem itself.

    Comparative Contex

    1. AI Search Platforms: Similar debates have emerged around AI-generated search summaries reducing website visits.
    2. Media Compensation Models: Countries such as Australia introduced bargaining mechanisms between digital platforms and news publishers.

    Does the Rise of Information Agents Deepen Market Concentration and Digital Inequality?

    1. Platform Entrenchment: Google’s advantage lies in unmatched digital infrastructure across search, email, navigation, devices, and browsing behaviour.
    2. Lock-In Effect: Users embedded in Google’s ecosystem may find switching increasingly difficult due to personalized AI assistance.
    3. Subscription Divide: The information agents may initially launch for Google AI Pro and Ultra subscribers, creating differentiated access.
    4. Informational Inequality: Wealthier users may gain persistent AI assistants while others continue manual searches, widening informational asymmetries.
    5. Market Power Consolidation: Persistent agents could further strengthen dominance of already large digital platforms.

    Are Existing Legal and Governance Frameworks Adequate for AI Agents?

    1. Liability Gap: No clear framework exists regarding responsibility if an AI agent nudges users toward harmful financial or medical outcomes.
    2. Assistant-versus-Advisor Problem: Companies classify agents as “assistants” rather than advisors, limiting accountability.
    3. Regulatory Lag: Technology deployment currently outpaces legal adaptation.
    4. Need for Algorithmic Transparency: Users require clarity regarding how recommendations are generated and monetized.
    5. Data Governance Deficit: Existing laws inadequately address persistent behavioural monitoring by autonomous systems.

    Possible Governance Measures

    1. Consent Architecture: Ensures granular and revocable consent mechanisms.
    2. Transparency Mandates: Requires disclosure regarding data collection, recommendation logic, and commercial influence.
    3. Publisher Compensation: Develops fair economic arrangements for AI-generated content extraction.
    4. AI Liability Standards: Establishes responsibility for harmful outcomes from automated recommendations.
    5. Bot Governance Framework: Regulates autonomous web crawling and infrastructure burden.

    Conclusion

    Google’s information agents represent a transformative shift from search-based internet use to persistent AI-mediated interaction. While the model promises convenience and efficiency, it intensifies concerns relating to privacy, concentration of digital power, infrastructure strain, and publisher sustainability. The challenge for policymakers lies in balancing technological innovation with data protection, platform accountability, fair digital markets, and preservation of an open web ecosystem.
