What makes 2021 Physics Nobel Prize special?

Physics Noble Prize Laureates

This year Physics Noble Prize has been divided among three Scientists:

Syukoro Manabe (USA)

Klaus Hasselmann (Germany)

Giorgio Parisi (Italy)

The Royal Swedish Academy of Sciences committee jointly decided to award these three scientists with the Noble Prize in Physics. The work of the three Laureates is different in various aspects however they share monotony in solving the complex problems of the world with the help of physics.

The work of two Laureates Syukoro Manabe and Klaus Hasselmann is related to climate change, how it affects the world today following the continuing burning of greenhouse gases since the Industrial Revolution. They have designed computer models that help measure the earth’s climate and predict how far the environment would be increasing because of the rising global warming.

Manabe in his research discovered that if you double the CO2 in the atmosphere, the temperature would increase by 2 degrees Celsius. And Klaus made an analogy between the rapidly varying weather and slowly varying climate. Here he explains his work with the help of Einstein’s Brownian motion which says, the rapid weather fluctuations influence climate.

Klaus further adds that the weather on the time scale of days influences the oceans on the time scale of years.

The third Noble Laureate Giorgio Parisi has a little different contribution to physics. He won the prize as a result of successfully presenting the evidence in the physics field which help understand the difficult and chaotic phenomenon. His work is applicable to varying fields, such as biology, mathematics, neuroscience, and the growing machine learning processes.

Why does this Noble Prize matter?

The biggest challenge this planet faces today is climate change. The Paris climate accord 2015 signed by 196 parties, maneuvered a climate policy to restrict the rising temperature at 1.5 degrees Celsius by 2100 years. However, the limit of 1.5 degrees Celsius is going to be surpassed at the end of this decade in 2030, almost 70 years earlier than predicted in the accord.

This award honors the Climate Scientists whose work has led to the discovery of how carbon dioxide will change the scale of the environment in the coming few years. If the climate is not tackled today, it will have a grieving impact in the future and might not be possible for anyone to retreat anytime soon. This Noble prize is also important because it has been announced before the United Nation’s forthcoming Climate Conference in November 2021.

Thanks for your company!

Emily Elizabeth Dickenson: The greatest Poet

Waqar Ahmed | The Productivity Science Hope is the thing with feathers That perches in the soul, And sings the tune without the words, And never stops at all, - And sweetest in the gale is heard; And sore must be the storm That could abash the little bird That kept so many warm. - I’ve heard it in the chilliest land, And on the strangest sea; Yet, never, in extremity, It asked a crumb of me. In the thorns, we found strength and in flowers we found pain. That is the situation you caught in when you read the lines of Emily Dickenson. The finest poet of the 19 th century enlightened with the figments of death and immortality in her words. Emily is a great American poet and deserves to be known across the globe for her art. Her writing had brought her to a point where there was no fear to be afraid of. Not even her death. America at that time was facing some identity challenges as women were yet to be emancipated from their Kitchens and there were no vote ri...

Steal like an artist by Austin Kleon

Book Cover (Source: Tapan Desai) Summary (informal) Everyone wants to become something in his life. There’s no single formula to achieve one’s desired destination. In this rapidly changing information climate, everything has become more competitive and less rewarding for those who do not pay more attention to details. It is healthy to settle one’s mind to steal ideas productively from those who have experimented with them successfully. There’s no harm in stealing ideas as there’s nothing as new to the world today given the scale of information exchange around the globe due to the Internet. Since everything is already available on Google, one must go there and copy from authentic sources. Make changes in it and sell it to the world. While you are working on the project, keep an eye on wrongs that might discredit the efforts. Copying from a single person is plagiarism, but doing the same thing from more than one is research. A good ar...

Make your Morning Special

Waqar Ahmed | The Productivity Science There is a blessing in the morning routine, early wake-up, doing breakfast, and starting off with the most important work. Nature runs its clock between the sunrise and its fall. It is also the most productive time a human can ever have. When someone starts off the day with morning, 99% chances are that everything will go well. Remember, the start of the day with a positive attitude is important. Remind yourself that you are the most important biological creature on this earth and you have a purpose to serve. Start with light work in the morning such as reading a newspaper. It will set your tone for the rest of day because you’re signaling your mind that if you can accomplish this little act, you can do anything for the rest of your day. Morning is precious time. Be careful and divide your day from important to less important things. As the day goes by, so does your potential. Make sure that by the end of your day you have accomplished remark...
