How Much Water Is on Earth? Total Water and Freshwater Explained

THE CRA PERSPECTIVE • EARTH SCIENCE How Much Water Is There on Earth? Can our planet ever run out of water? Exploring Earth's enormous water reserves, the freshwater shortage and the future of humanity. Water is one of the most extraordinary and essential resources on our planet. Our planet is called the Blue Planet for a reason. Approximately 71% of Earth's surface is covered by water. But does that mean we have an unlimited supply of water for human survival? Look at the oceans, rivers, lakes, glaciers and countless streams across the world. Water seems almost endless. It falls as rain, flows through rivers, disappears into the ground, freezes into ice and rises into the atmosphere as water vapour. Yet billions of people experience water shortages. Some communities struggle to obtain safe drinking water, groundwater reserves are declining in several regions, and pollution is making important water sour...

🔬🌍 INTERNATIONAL DAY OF MEDICAL PHYSICS – NOVEMBER 7

 Honoring the Science Behind Modern Medicine
📅 Shared by CRA | https://craarts.blogspot.com


“Invisible hands that guide the healing rays.”


Each year on November 7, the world observes the International Day of Medical Physics (IDMP), a global tribute to the vital yet often unseen role of medical physicists—the professionals who bridge physics and healthcare to save lives using science.

This day also marks the birthday of Marie Skłodowska-Curie, the Nobel Prize-winning physicist who pioneered the use of radiation in medicine, making November 7 a fitting tribute to her legacy and the future of medical physics.


⚕️ What Is Medical Physics?

Medical physics is a specialized branch of applied physics focused on the development and application of physics principles in diagnosis, treatment, and prevention of diseases.

Key areas include:

  • Radiation Therapy: Ensuring precise cancer treatment using targeted radiation.

  • Medical Imaging: Improving accuracy in MRI, CT, X-ray, PET, and ultrasound.

  • Nuclear Medicine: Monitoring and applying radioisotopes in diagnosis and treatment.

  • Radiation Protection: Keeping patients and healthcare staff safe from exposure.


🧬 2025 THEME: “Medical Physics: Securing Trust in Radiation Medicine”

This year's theme emphasizes the crucial role of trust, safety, and precision in modern medical technologies that rely on radiation. From cancer centers to neonatal ICUs, medical physicists ensure every scan and treatment is both effective and safe.


👩‍🔬 In Tribute to Marie Curie

Born on November 7, 1867, Marie Curie’s groundbreaking research on radioactivity revolutionized the world. She was the first woman to win a Nobel Prize, and the only person to win in two scientific fields—Physics and Chemistry.

“Nothing in life is to be feared, it is only to be understood.”
— Marie Curie


🩻 Why This Day Matters

  • 🌐 It raises awareness of the life-saving science behind medical equipment.

  • 🎓 Encourages students to explore careers in STEM and medical physics.

  • 🏥 Highlights the contributions of physicists in clinical environments.

  • 🛡️ Promotes radiation safety and ethical practices in healthcare.


🖌️ Artistic Reflection

As an artist, I’m fascinated by the unseen beauty of energy, waves, and radiance. Medical physics isn’t just science—it’s a form of healing light. From the silhouette of a lung on a scan to the curves of radiation beams, there's a quiet artistry in how precision and compassion meet.

“Every dose of radiation is a silent stroke of healing—delivered with mastery, backed by science.”
— CRA

Rejected by KFC, Remembered by the World: The Jack Ma Story

THE CRA PERSPECTIVE • SUCCESS & LEADERSHIP Rejected by KFC, Remembered by the World: The Jack Ma Story How rejection, persistence, curiosity and an unconventional vision helped shape the journey behind Alibaba. RESILIENCE • ENTREPRENEURSHIP • POSSIBILITY Sometimes, the door that closes in your face becomes the beginning of a journey you never imagined. Imagine applying for a simple job, standing among 24 candidates, and discovering that you are the only person who has not been selected. For many people, that moment could become a lasting source of embarrassment, self-doubt or resentment. For Jack Ma , the Chinese entrepreneur associated with Alibaba, this rejection became one of the most widely repeated episodes in his personal story. He has publicly recalled that 24 people applied for a KFC job in his city, 23 were accepted, and he was the one who was rejected. But the real story is not about a fast-food job. It is about wh...

Same Tree, Different Eyes: The Psychology of Perspective

THE CRA PERSPECTIVE • HUMAN PSYCHOLOGY Same Tree, Different Eyes Why we see the world differently—and how perspective shapes our decisions, relationships and lives. We do not always see things exactly as they are. We often see them through the lens of who we are. Imagine a large, beautiful tree standing beside a quiet road. Its branches stretch towards the sky, its leaves dance in the breeze, and its shade offers relief from the afternoon sun. A child might see a place to discover birds and nests. A carpenter might see the possibility of creating a table or a chair. A woodworker might think about timber. A businessperson might calculate its commercial value. An environmentalist might see biodiversity, ecological balance and the importance of conservation. The tree has not changed. Its physical presence remains the same. Yet the thoughts, emotions and possibilities it evokes are remarkably different. This simple observation ope...

Google Dreambeans AI in India: How It Works

THE CRA PERSPECTIVE • AI & TECHNOLOGY Google Dreambeans AI Arrives in India How an experimental AI app transforms everyday digital activity into personalised stories, ideas and discoveries. What if your AI assistant could quietly connect the dots in your digital life and prepare a personalised collection of stories, ideas and recommendations for you each morning? Imagine opening your phone and finding a beautifully illustrated suggestion for a place to visit, a hobby to explore, a reminder about an upcoming event or an activity connected to something you recently searched for. Instead of typing a prompt and starting from scratch, an AI system has already prepared a small collection of ideas based on the information you have chosen to share. This is the idea behind Dreambeans , an experimental artificial intelligence application developed by Google Labs. The app has now arrived in India, bringing a new approach to personalised AI experiences. ...
