 The history of science is the story of how humans have tried to understand the natural world using observation, experimentation, and reasoning. It spans from ancient civilizations to the modern era of space exploration, AI, and quantum mechanics. Here’s a chronological overview, divided into key historical periods: 🏺 1. Ancient Science (Before 500 CE) 🔹 Mesopotamia & Egypt Early mathematics, astronomy, and medicine. Developed calendars, geometry (for agriculture, architecture). Papyrus medical texts (e.g., Ebers Papyrus ). 🔹 Ancient Greece Thales , Pythagoras , Hippocrates , Plato , Aristotle . First attempts at rational explanations (without gods). Earth-centered (geocentric) universe model by Ptolemy . 🔹 India & China India : Decimal system, zero, Ayurvedic medicine, astronomy ( Aryabhata ). China : Compass, seismograph, herbal medicine, gunpowder, papermaking. 🏰 2. Medieval Science (500–1500 CE) 🔹 Islamic Golden Age (8th–13t...

 Here are 10 facts about the human heart in Hindi: 1. मानव हृदय एक मांसपेशी का एक अंग होता है जो रक्त को शरीर के अन्य अंगों में पंप करता है। 2. यह हृदय एक मशीन के रूप में काम नहीं करता है, बल्कि एक स्वच्छ और स्वयं संचालित अंग होता है। 3. एक औसत मानव हृदय का वजन लगभग 250 ग्राम होता है। 4. हृदय के दो पंप होते हैं - दाहिना पंप जो रक्त को शरीर के अन्य भागों में पंप करता है, और बाईं पंप जो रक्त को फेफड़ों में भेजता है। 5. हृदय में चार मुख्य रक्त वाहिकाएं (वेन) होती हैं - दाहिने और बाएं ओर्टा (arteries) और दाहिने और बाएं वेन्स (veins)। 6. जीवन भर में, हृदय लगभग 2.5 बिलियन दाएं और बाएं धड़कनों को प्रस्तुत करता है। 7. हृदय के दिलचस्प ढंग से काम करने के लिए विशेष विद्युत चार्जित तंत्र होता है जिसे सिनोआट्रियल नोड (सीएनए) कहा जाता है। 8. दिल की धड़कन को एक साधारण मानव शरीर की शीर्षवर्गीयता के रूप में दर्शाया गया है, जो महसूस की जा सकती है। 9. हृदय एक आम वायुशोधित चम्पर (एम्ब्युलेंस) यानी दिल चम्पर बना सकता है जो दिल रोगियों के लिए उपलब्ध होता है। 10. स्वस्थ हृदय के लिए एक स्वस्थ जीवनशैली अपन...

 Chandrayaan-3 is a lunar exploration mission by the Indian Space Research Organisation (ISRO). It is the third mission in the Chandrayaan series, following the successful Chandrayaan-1 and Chandrayaan-2 missions. The primary objective of Chandrayaan-3 is to further explore the Moon's surface and enhance India's capabilities in space exploration. The Chandrayaan-2 mission, launched in July 2019, had an orbiter, lander (Vikram), and rover (Pragyan). Unfortunately, the lander lost communication during the descent phase, and the mission did not achieve a soft landing on the lunar surface. Despite the setback, the orbiter continues to orbit the Moon and conduct scientific observations. After the partial success of Chandrayaan-2, ISRO decided to plan and launch Chandrayaan-3 with improvements and lessons learned from the previous mission. The primary focus of Chandrayaan-3 is to attempt a successful soft landing on the Moon's surface.

 Science is a systematic and organized way of acquiring knowledge about the natural world through observation, experimentation, and analysis. It is a methodological approach used to understand the physical and natural phenomena, as well as to make predictions and explain how things work. The main goal of science is to provide explanations for the various phenomena and events that occur in the universe. Key characteristics of science include: 1. Empirical: Scientific knowledge is based on empirical evidence, which means it is obtained through observation and measurement of the natural world. 2. Objective: Scientists strive to remain unbiased and objective in their investigations, using rigorous methodologies to minimize personal biases and preconceptions. 3. Reproducible: Scientific experiments and observations should be reproducible by other researchers under similar conditions to ensure the validity of the findings. 4. Falsifiable: Scientific theories and hypotheses must be capabl...

Chemical  characteristics of Sewage Chemical characteristics of sewage indicate the sewage pollution extent and the type of treatment required. The basic chemical characteristics with test for determining are: a. Total solid, Suspended and Dissolved solid and  Settleble Solid: Present in small amount (0.1%), solid can be in four different forms. These solids can be  both  organic  and  inorganic  matter.  Organic  matter  consist  of  carbohydrate, fat, nitrogenous compounds etc. and inorganic matter consist of minerals and salts. Total solid is the sum of all kind of solid. The  estimation  of  suspended  solids,  both  organic  and  inorganic,  gives  a  general  picture  of  the load  on  sedimentation  and  grit  removal  system  during  sewage  treatment.  Dissolved  inorganic fraction is to be consi...

  Properties of Materials 1. Strength: Strength is the ability of s material to withstand various forces to which it is subjected during a test or in service. It is usually described as tensile strength, compressive strength, shear strength etc. 2. Stiffness: It is that property of the material due to which a material can resist deformation. 3. Toughness or Tenacity: It is the ability of material to withstand bending or application of shear forces without fracture. It is represented as energy absorption per unit volume of the material. 4. Ductility: It is the property of the material to withstand elongation or bending. Due to this property wires are made by by drawing out through a hole. 5. Brittleness: It is the opposite of ductility. Brittle materials fail suddenly without warning when stressed beyond their strength. They can not accommodate much change in shape without rapture. 6. Hardness: It is the ability of material to resist abrasion or cutting, or scratching etc. A hard...

Sanitary sewage or Dry weather flow (DWF): The flow of sanitary sewage alone in the absence of storms in dry season is known as dry weather flow. It includes waste water from infiltration, commercial establishments, public spaces and industrial zones. Sources of sanitary sewage:   Waste water generated by following supply source a. Public water supply: Water supplied by the municipal authority for domestic or commercial purpose turns into waste water after some losses.   b. Private water supply  Water supplied by private authority for different public spaces like schools, colleges, commercial units etc. c. Private source  Private water sources such as well, ground water pumping, canals etc. d. Infiltration of ground water   Water accumulated in the sewer line by transmission of ground water though joints. e. Unauthorized connection  Any connections that are not considered which designing of sewer line.   Common examples are connecting s...
