Plaster of Paris

-

Representational 


Okay, fellow class 10th buddy! Let's unravel the mystery of why calcium sulphate hemihydrate has such a fancy name: "plaster of Paris." 
Imagine this: you're in Paris, building a beautiful castle out of...plaster!

 

But not just any plaster. This special plaster comes from a magical place called Montmartre, just outside the city.
**Here's the story:**

1. **Montmartre Magic:**


 Montmartre has hills filled with a special rock called "gypsum." When heated, this gypsum transforms into a fine, white powder called "calcium sulphate hemihydrate." It's like the rock learns a cool new trick after taking a fire bath!


2. **Parisian Plaster Power:** Back in the 1700s, Paris wanted to spruce up its buildings with shiny plaster decorations. Guess what they used? That's right, the calcium sulphate hemihydrate from Montmartre! It sets quickly and smoothly, perfect for creating intricate designs and shapes.
3. **A Name is Born:** Soon, everyone was buzzing about this amazing plaster from Paris. They started calling it "plaster of Paris," paying homage to its special origin. And the name stuck!
So, even though "calcium sulphate hemihydrate" sounds scientific, "plaster of Paris" has a cool historical story behind it, reminding us of the magical transformation that happens in those Montmartre hills.
**Bonus Tip:** Remember, this special plaster isn't just for fancy decorations. It's also used for casts, because it hardens quickly and supports broken bones! 


So, next time you see a cast, you can imagine a little bit of Parisian magic inside it.
I hope this explanation makes sense and adds a fun twist to this scientific term! Keep exploring the world of science, young Einstein!

This speech was written by Mohit, it was delivered on the occasion of National Youth Day at FIS (Manasa).     Speech Swami Vivekananda, in his childhood he was called Naren, was born on January 12, 1863 in Kolkata. His father, Vishwanath Datta, was an advocate in the High Court of Kolkata. Vishwanath had a deep interest in music and he thought of it as the source of much innocent pleasure. He used to read Bible and recite poems of Persian poet Hafiz with great joy. Naren's mother, Bhuvaneshwari Devi, was extraordinarily intelligent and it was her habit to study Sanskrit scriptures the Ramayan and the Mahabharata.     When Naren was studying in sixth class of Pandit Ishwar Chandra Vidyasagar's Institution, he was told that he would have to study English. He was not willing to do so. It was a foreign language, he said, so why should he learn it? The teachers persisted and Naren went home crying to his parents and there his father made him aware about the Joy of Learni...

 Bhagat Singh's association with the Hindustan Socialist Republican Association (HSRA) was a pivotal chapter in India's freedom struggle. Here's a detailed account of his journey into the organization: --- Early Influences and Political Awakening 1. Family Background:      Bhagat Singh was born into a family deeply involved in the independence movement. His father, Kishan Singh, and uncle, Ajit Singh, were active revolutionaries, exposing him to nationalist ideas from a young age. 2. Impact of Jallianwala Bagh (1919):      The massacre at Jallianwala Bagh in 1919, when Bhagat Singh was 12, radicalized him.

अज्ञेय जी कहते हैं ‘मेरा सच्चा पाठक वही है, जो मेरा लिखा हुआ समझे और उसके अनुसार कर्म करे।’ शेखर को लगता, उसके शरीर में कोई परिवर्तन हो रहा है। उसे लगता, वह बीमार है; उसे लगता, उसमें बहुत शक्ति आ गयी है; और वह, अपनी दुम का पीछा करते हुए कुत्ते की तरह, अपने ही आसपास चक्कर काटकर रह जाता...      अपने शरीर की माँग वह नहीं समझता, लेकिन उसे लगता, यह माँग कुछ अनुचित हैै, कुछ पापमय है। और वह चाहता कि किसी तरह उसे दबा डाले, कुचल डाले, धूल में ऐसा मिला डाले कि उसका पता भी न लगे, चाहे शरीर ही उसके साथ क्यों न नष्ट हो जाय...      वह मन उस पर से हटाना चाहता। यह तो वह जानता नहीं था कि किस तरह से शरीर से मन हटाए, लेकिन कविता में रुचि थी, और इसलिए उसे आशा थी कि वह उसमें अपने को भुला सकेगा। वह हर समय, हर प्रकार की कविता पढ़ने लगा। उसने संस्कृत-कवि पढ़े, उसने उर्दू से अनुवाद पढ़े, उसने जो कवि उसकी पाठ्य-पुस्तकों में थे — Tennyson, Wordsworth, Shelley, Christina Rossetti, Scott — सब पूरे पढ़ डाले। फिर उसने वे कवि पढ़ने आरम्भ किये, जो उसकी पुस्तक...
