The Positive Impact of COVID-19

Nature is relaxing 

 Despite the coronavirus threatening the world, it has some positive sides too. As the Covid-19 pandemic continues its blow, one can witness dramatic changes in people’s lives. And it already overshadowed other medical problems. Doctors and researchers notice unexpectedly positive side effects of the abrupt shifts in human behaviors in response to the pandemic. Moreover, prolonged lockdown is relieving nature with a reduction in human activities. Skies are bluer, the crime rates are lower.

Due to the lockdown, the pollution level fell dramatically and is still heading down. Nitrogen dioxide (NO2) is a toxic gas liberated from buses, cars, factories, etc. According to WHO, NO2 causes significant inflammation of the airways (lungs and trachea) at concentrations above 200 micrograms/m3. Now, vehicles and factories are under shutdown which results in the decrement of NO2 concentrations. Polluted cities like Chennai, Delhi, Bhilai etc. have experienced 100-200% of the decrement of NO2 toxic gas in the air. In most of the cities of India like Delhi and Tamil Nadu the concentration of NO2 is falling dramatically. 

Particulate matter 2.5 (PM2.5) is one of the most harmful forms of air pollution. It lies in the group I cardiogenic category. PM 2.5 is a microparticle which moves from lungs to the bloodstream and causes respiratory problems like asthma, heart attack, and causes premature death. According to the WHO, more the 4 million people are dying due to PM 2.5 every year. As a result of the lockdown, the concentration of PM 2.5 falls dramatically and saves millions of lives. 

These are the reasons behind the bluer sky and clear stars during the night as we see in the photos of Kathmandu. This prompted the addition of beauty in nature.

Researchers from Stanford University have collected the data of PM 2.5 from different cities of China and compared them with mortality rate. They conclude that the lockdown is likely to save 700 lives in China just by reducing air pollution in 1 month. 

The high amount of carbon dioxide (CO2) emission causes climate change and greenhouse effects. Lockdown triggered a significant fall in carbon emission by approx. 5%. According to the chair of a network of scientists, the decline could be the largest since world war II.  

With the days coming back to normal after the lockdown, the carbon emission and pollution revive too. But till then a lot of industries might already face complete loss compelling workers to be jobless. The government can act on such circumstances to push the renewable energy industry. Gradually, the government should focus more on renewable energy. The lockdown experience can be a milestone for purifying nature

The Core of Math Anxiety: Mathematics is Abstract and Our Purpose for Learning it is Concrete Think of the moment when kids understand that fingers —  not just their fingers  — is a way to count.  T hink also when they count two for legs on a chicken and also time passage in terms of days. There is a ton of abstraction that we all fall into right from the beginning. The abstraction leap from something like three fingers to the number “3” might be one of the biggest that we rarely acknowledge to the time that it deserves. The proof of that is that a common refrain in math education is “when are students going to stop using their fingers for counting?” My response is “hopefully never”, meaning that there is something unresolved with students that needs attention and time to. The pandemic regrettably proved that education has no interest/idea in shifting the historic purpose of mathematics — practice, perform, and practicality — into something more aligned to the abstract origins and beau
