Global Climate Change

Climate change is the change in average patterns of natural events or phenomena such as temperature and rainfall over time in a region or around the world. Changes may occur naturally as well as occur due to human activities posing threats to nature. How Climate Change Occur / Causes of Climate Change There has been a drastic increase in climate change since the industrial revolution around the globe. Greenhouse gases are the primary cause behind these climatic changes. These gases trap and hold light energy reaching the earth’s surface from the sun, and radiate it in the form of infrared heat. Eventually, this process causes an increase in the average temperature of the atmosphere of our globe. Carbon dioxide (CO2), methane (CH4), nitrogen oxide (N2O), and chlorofluorocarbons (CFCs) are major greenhouse gas contributors.  Carbon DiOxide (CO 2 ) .  CO2 is generated due to natural processes (i.e. volcanic eruptions) as well as through human activities (deforestation and burning of fossi

Marie Curie the Scientist - History, Nobel Prizes, Achievements & Facts



History of Marie Curie

    Polish-French Physicist Maria Salomea Sklodowska commonly known by French version of her name “Marie Curie” was a Polish (Poland was part of Russian Empire at that time) by birth. She was born into the family of a secondary-school teacher on November 7, 1867 in Warsaw, Poland. After completing her early education in Warsaw, she relocated to France (Paris) in 1891 to continue her studies at the Sarbonne

    She earned Licentiateships (at Sarbonne) in Physics and Mathematics. In 1894, she met her future life partner, Pierre Currie, a Professor in the School of Physics. She later married Pierre in 1895 and completed her degree as a Doctor of Science in 1903. Her husband Pierre Curie died in a tragic incident (caused by a street accident). Marie joined the University as a Professor of Physics.

Marie Curie’s 1st Nobel Prize – Physics Nobel prize winner 1903

    Marie Curie won her first noble prize for her momentous work in the Physics domain. She was the co-winner of the prize. The other two were her husband, Pierre Curie, and Henri Bacquerrel. She and her husband shared the Nobel Prize for their work on radiation phenomena (alongwith Henri Bacquerrel who discovered spontaneous radiation).

    Marie Curie, alongwith her husband, worked on the Phenomena by extracting Uranium from ore and found that the remaining part of the ore exhibited more activity than the pure Uranium, leading them to the conclusion that the ore carried some other radioactive elements. They discovered these elements to be Polonium and Radium. Marie herself coined the phrase "Radioactivity". According to her research, the activity of rays was dependent on uranium’s atomic structure and not on its form. The couple spent their time on Pitchblende, a crystallized form of Uranium oxide.

Marie Curie’s 2nd Nobel Prize – Chemistry Nobel prize winner 1911

    The 2nd Noble prize was presented to her in recognition of the discovery of Radium and Polonium (radioactive elements). Polonium was named after Madame Curie’s country of birth, “Poland”. She also worked on the isolation of Radium and studied the nature & compounds of these amazing elements. She produced Radium as pure metal in 1910, which led to the end of any doubts about the existence of the element.



What did Marie Curie discover?        They discovered Polonium and Radium by accident in 1898 while looking for uranium ore. They saw that the Uranium’s pitchblende was more radioactive than the Uranium separated from it. Conclusively, they discovered Polonium and Radium.

    Radium is now used in certain applications, such as industrial radiography, while being replaced in other fields by some other elements. Polonium, on the other hand, is used in antistatic devices and for research.

    Due to her enthusiasm for science and research, Madame Curie was connected to Science throughout her life. She died on July 4, 1934 at the age of 66. Despite her neutralization to France during her student life, Madame Curie kept connected her daughters with her mother tongue i.e. Polish and kept visiting Poland many times later in her life.

Did Universe Popped out of NOTHING

 If we succeed in getting rid of everything from a part of space i.e. from all the planets, stars, atoms, particles, even light and radiation etc, this space still have weight. It turns out that NOTHING is not nothing but it is something. How is that possible? Space is bubbling with virtual particles that pop in and out of existence. These particles do this in such a short time scale so the laws of classical Physics forgives the creation of these ghost particles which seem to come out of nothing. The laws of Quantum Mechanics allow this.  To visualize, consider an empty space within a proton. Since most of our physical world is made up of protons and neutrons, this so called empty space (inside protons) gives mass of proton. "Empty space is actually full of quarks and Gluon Field Fluctuations, so empty space is not empty" (Professor Derek Leinweber, University of Adelaide).  Here is the simple visualization. 0 represents nothing. But 0 can also be expressed as 1+(-1) or 1000

Magnets and Magnetism - Interesting Magnet Facts for Kids

Historical Background of Magnets      Without the use of magnetism, we can’t even imagine the existence of light and there wouldn’t be most of the technology that we see today, use today, and utilize in our daily routine. The Greeks were the first to discover magnets. There was a village named Magnesia in an ancient Greek city in Ionia (we know this stone as Magnet today because of the village of "Magnesia"), where a shepherd found a magnetic stone (Lodestone) and observed the magnetism when nails from his shoes and metal pieces in his stick got attracted to the stone. People began to believe it was a healing element.      People used to use the stars and the sun to find their way around. But after the discovery of magnets, the Chinese were the first to use them as a tool for magnetic compasses. Magnets come in different sizes - as large as the earth and as small as the cell. Yes, you read it right. Our planet Earth is itself a big giant Magnet.  The history of magnets goes b

How Sun Works: Quantum Tunneling

Do you know if the Sun was fueled by Gasoline or wood, it would have been burnt out in just a few hundred years, So how it is still here after 4.5 billion years.... Physics!!! The Sun is like a big nuclear reactor in the sky. It is fueled by nuclear reactions that fuse Hydrogen atoms into Helium, other heavier elements and energy (in the form of Photons) in the process. In this way the Sun is slowly converted into mass and energy in the form of sunlight and have more than enough fuel for us for billions of years. But nuclear fusion is not as simple as it looks. Fusion is the process that powers the Sun and the stars. It is the reaction, in which two atoms of Hydrogen fuse together to form an atom of Helium. In the process some part of hydrogen is converted into energy. On earth we need to heat hydrogen hundred times hotter than that of the Sun to set a fusion reaction. Sun has a temperature of 15 million Celsius degrees in its core whereas it requires more than 100 million Celsius deg
