    On June 16, 1963, Valentina Tereshkova made history as the first woman to venture into space. Her achievement marked a significant milestone in the Space Race between the USA and the USSR during the Cold War.

    About Valentina Tereshkova’s Space Journey

    • In 1962, Tereshkova was selected among five women for the Soviet space program, aiming to achieve ‘gender equality’ in space exploration.
    • The USSR’s decision to send a woman into space was partly influenced by the success of Yuri Gagarin’s mission in 1961 and the desire to surpass the US in space achievements.
    • Tereshkova’s affiliation with the Communist Party and her skills as a parachutist were factors in her selection for the Vostok 6 mission.

    The Mission – Vostok 6

    • On June 16, 1963, Tereshkova piloted Vostok 6, becoming the first woman to orbit the Earth.
    • She spent 71 hours in space, completing 48 orbits around the Earth during her mission.

    Impact and Legacy

    • Tereshkova’s mission boosted Soviet prestige in the Space Race, following earlier successes like launching Sputnik-1 in 1957 and Yuri Gagarin’s historic flight in 1961.
    • Despite her pioneering role, the USA would later achieve milestones like the Apollo moon landings, surpassing Soviet achievements in manned space missions.
    • Tereshkova continued to advocate for women’s participation in space exploration and held prominent positions in Soviet politics and the Air Force.

    Indian Women in Space 

    Indian women have made significant contributions to space exploration, marking milestones and inspiring future generations. Here are notable Indian women who have ventured into space:

  • Quantum Physics Behind Diapers: How they absorb so much Liquid?

    Why in the News?

    Understanding the absorbency of diapers through the Quantum physics of water absorption and contrasting materials that do or do not absorb water.

    Absorption in Diapers: How it works?

    • Absorption depends on Microscopic forces and Material properties. Water molecules are attracted to materials like cotton due to their structure.
    • Cotton, a network of polymers with ions, absorbs water effectively by attracting water molecules.
    • For large fluid absorption like in diapers, Super-Absorbent Polymers (SAP) are crucial.

    What are Super-Absorbent Polymers (SAP)?

    • SAPs are synthetic materials with the ability to absorb and retain large amounts of liquid relative to their own mass.
    • They are commonly used in products like diapers, sanitary napkins, and other absorbent hygiene products.
    • SAPs are typically cross-linked polymers, meaning their molecules are bonded in a way that creates a network capable of absorbing water molecules.

    Examples:

    1. Sodium Polyacrylate: This is one of the most common types of SAP used in diapers. It forms a gel-like substance when it absorbs liquid.
    2. Polyacrylamide: Another type of SAP used in various applications, including agriculture and wastewater treatment, due to its high water-absorbing capacity.

    Quantum Physics Insight of SAP

    Quantum physics plays a fundamental role in understanding the behaviour of super-absorbent polymers (SAPs), particularly in how they interact with water molecules at the atomic level:

    1. Electron Sharing: SAPs contain ions like sodium, which have a strong affinity for water molecules. This attraction is based on the principles of quantum physics, where atoms like sodium and oxygen prefer to share electrons to achieve stability. This shared electron arrangement allows water molecules to bond with the ions in SAPs, facilitating the absorption process.
    2. Quantum Mechanical Properties: At the quantum level, electrons behave as waves and can exist in shared states between atoms. This phenomenon allows for the formation of stable bonds between water molecules and SAP ions, enhancing the SAP’s ability to absorb large amounts of liquid.
    3. Energy States: Quantum physics explains how SAPs manage energy states during absorption. As water enters the SAP, energy is released due to changes in the electron configurations and bonding energies of the ions involved. This process is crucial for maintaining the gel-like structure of the SAP and preventing leakage.

  • Formula for Flapping Frequency across Flying and Swimming Animals

     

    Why in the news?

    • Researchers at Roskilde University in Denmark discovered a formula that correlates the flapping frequency of winged and swimming animals to their mass and wing/fins size.
      • The formula applies universally across a diverse range of species, from insects to birds, bats, penguins, whales, and even robotic ornithopters.

    Formula for Flapping Frequency

    • The formula was derived from Newton’s second law (F= mass x acceleration) applied to animals flapping wings to stay airborne.
    • Factors considered in the derivation included air density, wing size, and the forces generated by wing movements.

    Research Methodology

    • The researchers derived the formula theoretically from Newton’s second law, relating the force needed to stay airborne or submerged to the wing/fins’ motion, air/water dynamics, and animal mass.
    • They incorporated empirical observations into a constant C to account for specific shape and flight kinematics variations.

    Application and Validity

    • The formula’s validity was tested across various animals:
      • 176 insect data points (e.g., bees, moths, dragonflies)
      • 212 bird data points (from hummingbirds to swans)
      • 25 bat data points

    Formula Extension to Swimming Animals

    • The formula also predicts the frequency of fin/fluke movements in swimming animals.
    • Adjustments are made for water density and buoyancy effects, excluding fish with swim bladders.

    Limitations and Modifications

    • The formula applies well in conditions with high Reynolds numbers (Re), where fluid flow is streamlined.
    • At low Re values, where viscosity dominates, modifications are needed.
    • The equation holds as long as animal density variations do not exceed a factor of ten.

    Insights and Future Research

    • Insights from the formula include understanding flight efficiency and potential evolutionary pathways for winged animals.
    • Future research aims to explore further insights hidden within the C constant, potentially revealing deeper principles governing animal flight and swimming dynamics.

  • What is an Electromagnet?

    PC: The Hindu

    Why in the News?

    Recently Scientists have designed a magnetic resonance imaging (MRI) scanner that costs a fraction of existing machines, setting the stage for improving access to this widely used diagnostic tool. So we need to know about the Electromagnet.

    What is an Electromagnet?

    • Invented in 1824 by William Sturgeon, electromagnets revolutionised technology.
    • Sturgeon was an English physicist and inventor who discovered that wrapping a coil of wire around a piece of iron and passing an electric current through the wire produced a magnetic field.
    • Electromagnets are used in Loudspeakers for sound reproduction, Motors for mechanical movement., and MRI machines for medical imaging, etc

    How Electromagnets Work?

    • Electric current flowing through a wire generates a magnetic field around the wire.
    • Coiling the wire enhances this magnetic field by concentrating it within the coil’s core.
    • This configuration creates an electromagnet, where the strength of the magnetic field is directly proportional to the current flowing through the coil.
    • The magnetic flux density so generated is measured in ‘Tesla’.

    Enhancing Magnetic Strength with a Core

    • Coiling the wire around a magnetic material (core), such as iron or steel:
      • Amplifies the magnetic field produced by the electric current.
      • Ferromagnetic materials like iron align their internal magnetic domains with the external magnetic field generated by the coil.
      • This alignment significantly increases the overall magnetic strength of the electromagnet compared to a non-magnetic core.

    Persistence of Magnetization

    • It refers to the property of a material to retain a certain amount of magnetization even after the removal of an external magnetic field.
    • Certain core materials exhibit retained magnetization even after the current ceases.
    • This residual magnetism is useful in applications requiring sustained magnetic fields, such as:
      • Superconducting electromagnets used in MRI machines, are capable of producing magnetic fields up to 30 Tesla.
      • Research electromagnets like those used in particle physics, which require stable and powerful magnetic fields.

    Who was Michael Faraday (1791-1867)?

    • Michael Faraday was a pioneering English scientist and physicist who made substantial contributions to the fields of electromagnetism and electrochemistry.
    • Faraday is best known for his experiments and discoveries in electromagnetism, which laid the groundwork for the principles of electromagnetic induction and the laws of electrolysis.

    Key achievements of Michael Faraday include:

    1. Electromagnetic Induction: He discovered electromagnetic induction in 1831, showing that a changing magnetic field induces an electric current in a nearby conductor.
    2. Electrochemistry: Faraday formulated the laws of electrolysis, which describe the quantitative relationship between the amount of material produced or consumed during electrolysis and the amount of electricity passed through the electrolyte.
    3. Faraday’s Laws of Electromagnetic Induction: These laws describe the fundamental principles of generating electricity using magnetic fields, forming the basis for the development of electric generators and transformers.
    4. Faraday Cage: He invented the Faraday cage, a device used to block electromagnetic fields.

  • No outcome in Bonn: why money is key to climate action

    Why in the news?

    The Bonn climate meeting failed to define a new climate finance goal, crucial for finalizing a sum exceeding $100 billion annually by the end of 2024.

    Key Highlights of the Climate Meeting in Bonn, Germany

    • Failure to Define New Climate Finance Goal: The recent climate meeting in Bonn did not make significant progress in setting a new climate finance goal. This new goal is supposed to replace the existing $100 billion per year target, which needs to be finalized by the end of 2024.
    • Outcome: The meeting only produced a lengthy 35-page “input paper” summarizing various countries’ demands and concerns, without providing any concrete numbers or agreements. This paper is expected to be developed into a formal negotiating draft for COP29 in Baku, Azerbaijan.

    Search for a New NCQG (New Collective Quantified Goal)

    • Importance of Climate Finance: Money is essential for climate action, including mitigation, adaptation, and other tasks like collecting and reporting climate data, which require substantial funds, especially in developing countries.
    • Existing Commitment: Developed countries had promised to mobilize $100 billion annually from 2020 to help developing countries fight climate change. This target is now being re-evaluated to increase the amount post-2025.

    Previous Assessment

    • Current Needs: It is widely recognized that developing countries now require trillions of dollars annually. A UNFCCC assessment indicated that these countries need about $6 trillion by 2030 for climate actions, with adaptation needs alone requiring $215 billion to $387 billion annually.
    • Energy Transition: The global shift to clean energy requires investments of about $4.3 trillion per year until 2030 and around $5 trillion annually thereafter until 2050 to achieve global net-zero emissions.
    • Developing Countries’ Demands: India has proposed that developed countries should provide at least $1 trillion annually after 2025, while Arab and African countries have suggested figures of $1.1 trillion and $1.3 trillion, respectively.

    Debate Over Contribution

    • Original Responsibility: According to the UNFCCC and Paris Agreement, only the 25 countries listed in Annexure 2, along with the European Economic Community, are responsible for providing climate finance to developing countries.
    • Shifting Responsibility: These countries argue that other nations, such as China, Gulf countries, and South Korea, are now economically capable and should also contribute. However, countries like China have stated they do not intend to take on additional responsibilities beyond their current efforts.
    • Developed Countries’ Stance: While acknowledging that the new target must be higher than the existing $100 billion per year, developed countries have not made any specific offers publicly.

    Way forward:

    • Clear Definition of Climate Finance: Establish a universally accepted definition of climate finance to prevent discrepancies in reporting and ensure transparency.
    • Precise Targets and Timelines: Set clear, incremental targets leading up to the final goal, with defined timelines for achieving these targets. This will provide a roadmap for both developed and developing countries.
