A new title “Keeping up with Time” has now been published and released to the http://www.amazon.co.uk website. The book is also available through book retailers in the UK like Waterstones, Foyles etc. The link to Amazon UK website is
At the present time, we see that facts are quite often manipulated and even manufactured to suit the purposes of the presenter. The mendacious molestation of facts, which is generally called the ‘alternative truths’, alters the perception of events and makes readers deeply suspicious of the authenticity of events. So, there is a need to bring out unadulterated basic facts so that readers can whet their appetite with truth. This book, Keeping up with Time, is an attempt to keep the discerning readers abreast with modern day issues, bare facts, basic analyses and unbiased opinions.
A wide variety of topical issues, articles, essays and blogs were presented in the book. Each one of these topics deals with issues where only factual and verified information was used and, as far as possible, complex issues have been dissected, simplified and explained in a clear and succinct way for the readers.
The book has been divided into three sections entitled ‘On Science and Technology’, ‘On Global Issues’, and ‘On Religion’. Each section has its own Glossary of Terms where difficult and unfamiliar terms and items have been explained, so that the topics in that section can be fully appreciated.
In the ‘On Science and Technology’ section, a wide range of technical issues of interest such as the black hole, gravitational waves, dark matter and dark energy, everything from nothing, entropy and the arrow of time etc. are presented. The most up to date information and research results have been incorporated and presented in a clear and succinct way.
In the ‘On Global Issues’ section, topics such as the inequality and inequity in capitalism, Solzhenitsyn’s views on communism, Tagore’s philosophical views, frailty in democracy, Orwellian viii dystopia, the illusion of reality, human population and many more are presented. As can be seen, some of the articles deal with historical events, while others look to the future.
In the ‘On Religion’ section, topics such as science and Islam, religion and morality, religious excesses in Islam, Einstein’s views on religion, the brutality of religious fanatics etc., are covered. In this section, views and opinions have been expressed somewhat provocatively; some readers may find that somewhat abrasive. But that was the purpose – to shake out the age-old views to bring people out of their comfort zones. But scrupulous attempts have been made to use only verified information and views.
During winter, more often than not, a large part of northern United States is pummelled by an Arctic blast, sometimes severe, sometimes less so, that lasts for a week or two. But this winter’s blast plunged not only Midwest and Northeast into a deep freeze with bone-chilling temperatures as low as negative 45 degrees Celsius, but it also tested the mettle of millions of people living in the Deep South, particularly Texas, a state that seldom experience sub-zero temperature.
An onslaught of freak wintery weather—a cocktail of heavy snow, sleet and chilling ice storm—with sub-zero temperatures knocked millions of Texans off the power grid and plunged them into deep freeze, the lowest being negative 12 degrees in Houston. Frozen and burst water pipes in homes and businesses were widespread. Unlike northern states, Texas is not equipped to handle ice, sleet or snow. As a consequence, hundreds of vehicles, including dozens of 18-wheeler, were involved in horrific and sometimes fatal pileups on untreated icy roads.
The recent extreme weather is not limited to the United States. That is because when the winter is extreme in one part of the hemisphere, it is often extreme all across the hemisphere. Thus, the “beast” from the Arctic hit Europe too. In January, Spain experienced a deadly snow storm with dangerously low temperatures. Even a tropical country like Bangladesh, especially the northern region, could not escape the wrath of the cold wave.
Snow fell hard in Greece and Turkey, where it is far less normal. Snow also fell in Jerusalem and parts of Jordan and Syria, while snow-covered camels in Saudi Arabia made for a rare sight. We also had more than our fair share of snow. In the lower Hudson Valley of New York, where I live, Mother Nature already dumped around 36 inches of snow since the last week of January, with more in the forecast. Most of the snow—24 inches—fell in a single storm event from January 31 through February 2.
Climate change deniers have often used cold winter weather to advance their argument that global warming is a Chinese hoax. In one infamous example, when an Arctic freeze descended on the northeast, including New York City, in December 2017, former US President Donald Trump tweeted, “Perhaps we could use a little bit of that good old Global Warming to protect against” harsh winters. Only an ignoramus person like him could make such a stupid statement!
It may be counterintuitive, but paradoxically, among the many factors, anthropogenic climate change is mainly responsible for the short-lived bursts of extreme winter weather that we have been witnessing in recent years. Indeed, there is strong scientific evidence that rapid heating of the Arctic caused by global warming is pushing frigid air from the North Pole further down south due to distortion of the polar vortex.
Under normal conditions, cold air is concentrated in a huge low-pressure gyre around the North Pole in an area called the polar vortex—about 15 to 50 kilometres above the Earth’s surface in the layer of the atmosphere known as the stratosphere. When the vortex is strong, the jet stream—a narrow band of strong, fast-flowing wind in the upper atmosphere that generally blows from west to east all across the globe—acts as a barrier between the spinning cold air in the north and the warmer air to the south. As a result, cold air remains trapped in the Arctic, making winters in the northern mid-latitudes milder.
How does global warming distort the polar vortex? It is well-known that the rise in global temperature is not evenly spread around the world. Because of the loss of Arctic ice which otherwise would have reflected a substantial amount of solar radiation back into outer space, average temperature in and around the North Pole is increasing about twice as fast as in the mid-latitudes. This is known as Arctic Amplification. Several studies show that the amplification is particularly strong in winter. Consequently, a rapidly warming Arctic weakens the jet stream, which in turn weakens the polar vortex to the extent that it becomes distorted, thereby spilling its cold air southward.
According to meteorologists, in a span of two weeks from December to January, Arctic Amplification gave rise to a phenomenon called Sudden Stratospheric Warming, in which temperatures in the atmosphere 15 to 30 kilometres above the Arctic jumped by nearly 55 degrees, from negative 80 to negative 25 degrees. This accelerated warming weakened the jet stream considerably and subsequently distorted the vortex so severely that it got knocked off the pole, resulting in a sudden plunge in temperature south of the Arctic Circle all the way to the US-Mexico border. Hence, the once-in-a-lifetime cold winter in Texas and other southern states.
Continued rise in global temperature will not necessarily mean an end to bitter cold waves during winter any sooner. One group of researchers believe that Arctic blasts will still occur, but their intensity will depend on how much greenhouse gases we vent into the atmosphere. It is very probable that they will become rarer over time, but the ones we are experiencing now will more likely persist and last longer. Another group says that warming in the Arctic will increase the chances of frigid polar air spilling further south, leading to more periods of extreme cold days in the future, much colder than the ones we are experiencing now.
Nevertheless, the recent weather pattern clearly demonstrates that both extreme heat and extreme cold can happen side by side. Besides, two to four weeks of cold snaps do not make a winter. They are short-term weather events, while climate is about long-term trends. Arctic blasts are, therefore, not enough to compensate for the overall warming of the climate across the planet. In fact, last year was one of the hottest years on record, with the average temperature surpassing a number of all-time highs. And it occurred without the warming influence of El Niño.
Finally, we are in a deep freeze amid global warming because our “senseless and suicidal” romance with fossil fuels has fundamentally changed the global weather systems for worse.

Today marks the fifth anniversary of the Paris Accord hammered out by more than 190 countries at the 21st Conference of Parties (COP21). The core objective of the accord is to save humanity from the existential threat posed by climate change. To that end, the participating nations agreed to keep the increase in the average global temperature to within 2 degrees Celsius while endeavouring to limit it to 1.5 degrees by the year 2100. Besides pledging to temper the rise in temperature, they agreed to restructure the global economy, phase out fossil fuels over the coming decades, switch to renewable sources of energy, embrace clean technology, and most importantly, reduce greenhouse gas emissions to zero by 2050.
The Accord gives every country the ability to set its own goals to confront the climate crisis, in line with their specific situation. Moreover, instead of demanding expeditious and deep cuts in fossil fuel usage, it allows parties to peak greenhouse gas emissions “as soon as possible” followed by a gradual decrease in order to reach the zero emissions goal. It is patently evident that such a vague timetable fits the interests of the major polluters, including the United States, China and India. Nevertheless, beginning this year, each nation is required to reassess its own reduction plans once every five years. However, there is no consequence or penalty if a country fails to reassess or falls short of the pledged reductions.
The Accord also requires nations to address “loss and damage” caused by climate impacts. Since the wealthy, industrialised nations are largely responsible for the backlog of climate changing emissions lingering in the atmosphere, they should compensate poorer nations for unavoidable loss and damage. But even after COP25 held in Madrid last year (2019), wealthy nations are playing Jekyll and Hyde roles—promising to cover losses while dragging their feet on providing new finance.
We are now a full five years into the Paris Accord which, according to the former US President Barack Obama, is supposed to make the “world safer and more secure, more prosperous and more free.” Are we really on course to transform our planet into one as envisioned by Obama? Are we winning the race against climate change? Did we succeed in slowing down the damage resulting from climate change? By all accounts, the Accord did not make an iota of difference in decelerating the progression of our planet, and subsequently our civilisation, toward climatic meltdown. On the contrary, climate change and its deleterious effects are accelerating, with climate-related catastrophes piling up, year after year.
Our planet is now almost at the breaking point. The environmental changes sweeping across the world are occurring at a much quicker pace than five years ago. As the Earth warms, we are witnessing more cataclysmic wildfires turning forests into carbon dioxide emitters, not to mention calamitous floods inundating nearly half of landmasses in countries like Bangladesh, Maldives, Thailand and so forth. Persistent droughts, fierce storms and an increase in extreme weather phenomena—derecho, microburst, bombogenesis, Frankenstorm and many more—are on the rise. The fingerprints of climate change since 2015 can also be seen in the exacerbation of internal and international migration patterns of climate refugees.
Scorching heat waves, of all places, in the Arctic region, are now more frequent and long-lasting. It is quite likely that 2020 will be among the hottest years ever, even with the cooling effect of this year’s La Niña. Seas are warming and rising faster, putting more coastal cities at risk of going under acidic water. Warmer waters are wreaking havoc on marine organisms forcing them to migrate away from their familiar habitats. Glaciers are melting at an alarming rate, thus disrupting availability of freshwater.
Climate-induced mayhem is taking a heavy toll on the Arctic region. The amount of Arctic sea ice whose whiteness normally acts as a natural reflector of heat back out of the atmosphere is dwindling so rapidly that the region may soon become ice-free. Loss of ice is also changing the Arctic terrain—making it greener and prettier, but at the expense of releasing copious amounts of carbon dioxide and methane trapped in the frozen soil, which in turn is making global warming even worse. Additionally, scientists have found evidence that frozen methane deposits in the Arctic Ocean, worrisomely called the “sleeping giant of the carbon cycle,” are escaping into the atmosphere. In fact, northern landscapes are undergoing massive change, with potential ramifications not just for the Arctic itself, but the world as a whole.
Permafrost in cold climate countries is thawing at breakneck speed, releasing, just like Arctic ice, large amounts of long-stored carbon dioxide and methane. In addition, viruses and bacteria that had been buried under the permafrost for thousands of years are being released into the environment, posing health risks to humans and other forms of life. Also, deforestation of the Amazon rainforest in Brazil, a vital carbon sink that retards the momentum of global warming, has surged to its highest level since 2008.
As for peaking of emissions, there is a cavernous gap between the sharp cuts in emissions required to meet the goals of the Paris Accord and current projections. In a recent report, World Meteorological Organization (WMO), a specialised agency of the United Nations, states, “There is no sign of slowdown, let alone a decline, in greenhouse gases concentration in the atmosphere despite all the commitments under the Paris agreement.” Rather, emissions from just about every country are still on the rise, thereby making it difficult to close the gap so as to achieve zero emissions by 2050.
The report further notes that even the coronavirus-related drop in emissions failed to make much of a dent in the amount of heat-trapping greenhouse gases accumulating in the atmosphere. Consequently, WMO warns that the world risks becoming an “uninhabitable hell” for millions unless we drastically cut emissions—by at least 7.2 percent every 10 years if we want to keep the rise in temperature to 1.5 degree Celsius. Otherwise, we will soon be north of 3 degrees Celsius.
The warning from WMO is corroborated by a study published last month in the British journal Scientific Reports, in which the authors assert that we have already passed the “point of no return for global warming.” The only way we can stop the warming, the authors say, is by extracting “enormous amounts of carbon dioxide from the atmosphere.”
The Earth’s average temperature has already risen by roughly one degree since the advent of modern record keeping in 1880. The devastation caused by one degree rise clearly indicates that an additional 1.5 – 2 degrees Celsius rise before the end of this century will lock in the changes to the Earth’s climate system that will be beyond our adaptive capacity.
Five years ago, the then UN chief lauded the Paris Accord as a landmark agreement, a potent message from world leaders who had finally decided to take on climate change in earnest. Five years later, in a complete volte-face, the present UN chief, in a speech at Columbia University in New York, issued a searing indictment of our utter disregard for the pledges made in Paris. He said, “The state of the planet is broken. Humanity is waging a suicidal war on nature, facing new heights of global heating, new lows of ecological degradation….”
So much for the Paris Accord! No wonder environmentalists believe that the Accord is meaningless, and with good reason. Indeed, the toothless, nonbinding, non-enforceable accord is an oversold empty promise—a gentleman’s handshake applauding the imposition of a global climate regime on humankind that is harming the planet in the name of saving it.
Finally, world leaders should realise that fixing the climate is not about making pretty promises at grandiose conferences held in glamorous cities. And if we rely on grandstanding and farcical Accords that give us false hopes, we will lose the race to keep our planet cool and habitable.

The COVID-19, a strain of coronavirus, sends an open letter to Humans on the occasion of Christmas 2020:
I am totally astounded and flabbergasted by the audacity you have displayed so far to my strength and ferocity. I may be small, a very small strain of coronavirus, but I am not weak. About a year and half ago, I evolved in your planet in the most populous nation on Earth. I thought I would have a fun time jumping from one to the other of 1200 million of your species. But Chinese government reacted very promptly, to my utter disgust, forcing me to stay within the confines of only 10 million or so Chinese. I will never forget or forgive the Chinese.
You know that I am a virus and hence I cannot live on my own. I need a body, preferably, a sick human body – a body with underlying problems like respiratory illness, diabetes, weak hearts having transplanted or bypassed, kidney problem, dementia and a lot of other problems, as my host. I do not want to go to anybody who is not prepared to be my host. After all, who does not like an easy prey, an easy meal? I hate going to a strong healthy body and fight it out with his or her body protection system.
You call your body protection or defence system an immune system. There is nothing immune from my attack. I am smaller than the smallest of a bacterium. You cannot normally see me or detect me unless you take me to an electron microscope. Even then, you have to be very careful detecting and photographing me. You take the shot from a wrong angle and you miss the point.
As I said, I need a host. I am not even alive on my own; unless I find a live cell in a live body like yours as my host within few hours, I would die. Once I get a host, I seek out the weak organ or tissue where I will have an easy task. First, I go to an organ of your body as an innocent bystander, observe how strong your organ is and how efficiently it is functioning. If the organ I am in is very efficient, then I tend to slip away to another organ. After all, I don’t want to sacrifice my life fighting a losing battle with a strong organ, whereas I could have a very comfortable life in another organ where I can flourish, multiply and even take over the whole organ!
When I multiply in an organ or capture the whole organ, I do not want to rest on my laurel. I want to go from your body to another body and keep capturing bodies. I use your cells as my hosts, your body as my survival machine. Before I make you inert (you know what I mean), I want to send some of us to some other human beings. I make you sneeze, make you cough, touch mucous membrane with your hands and pass it on to another person. I need your helping hand, literally. In fact, the more the merrier.
I hear that you have invented a vaccine against me, you want to kill me. It is then going to be an all-out war with me. I have lots of tricks up my sleeve – actually, up my spike to be precise. You think you can catch me by my spike, sort of catch a bull by the horn? No way. I will change my morphology such that as soon as you plan to bolt on to my structure, I will metamorphose to something else. Actually, I do not like the word metamorphose, as if I am doing a literary piece of work, I call it mutate. I mutate, I make your body cells mutate until those cells fail to function.
Mutation is the word I like most. As soon as you make something to catch me, you would find me that I have changed, I have mutated. It’s a cat and mouse game. And then you start the whole process all over again, back to square one. It goes on and on.
In all of this battle of wits, you forgot that I and my cousin called bacterium were the seed corns from which you were made. From the single cell bacteria to multicell bacteria and then to complex bacteria with RNA, DNA and mitochondria, that is how you came into being. Don’t forget all that of your past.
During the long evolutionary period of nearly four billion years, my cousin bacterium had done tremendous amount of work for you. You, all types of animals from antelopes to zebras, plants, fungi and algae were all made from innocent bacteria. My role was to terminate any unworthy species. Your fellow man, a very clever guy called Charles Darwin, very succinctly said, “struggle for existence and survival of the fittest.” I make that struggle as hard as possible and so don’t underestimate me.
May I remind you that during the last 450 million years when conditions on Earth were getting progressively favourable to you, as many as five times, 70 to 75% of all species of all living animals and plants had been wiped out. In addition, about 250 million years ago, nearly 99% of all life forms on Earth were obliterated. It was nearly going to start from a blank slate again. About 65 million years ago, dinosaurs were wiped out completely and that created conditions for life forms for you to evolve.
Life on Earth is a perpetual struggle. I quote again, Charles Darwin’s dictum, “struggle for existence and survival of the fittest” and this struggle and survival come from evolutionary process. If you, the human beings, think that you are clever enough and smart enough to override the evolutionary process, then you better think again.
One last point I would raise is that do not, not even in your dream, think that you are going to live on this Earth for ever. Since the dawn of life (any life) about 400 million years ago, 99% of all life forms have gone extinct. You came to Earth evolving from chimpanzee about 4 million years ago, less than 1.8 million years ago as Homo erectus or only about 200,000 years ago as Homo sapiens. A species on Earth lives, on the average, 4 million years and so your time is very much nearer the end. You had been destroying the fabric of Earth, massacring the environment, causing extinction to many species. Probably you had been creating conditions for your own demise. SO BE WARNED!
Science is a remarkable tool available to humans for understanding what is true about the world. It expanded the boundaries of our knowledge and challenged our preconceived notions of what reality is! Accordingly, scientific research has yielded a treasure trove of knowledge about many previously inaccessible domains of nature. The validity of such knowledge received confirmation from the fact that they led to new technologies that are helping us live longer, healthier and more enriching lives.
Scientific research does not take place in a vacuum. It is a social activity with a political overtone. And scientists are very much aware of the intricate interplay of science, society and politics. Perhaps one of the most persuasive arguments regarding the rightful place of science in modern society was brilliantly articulated by the American inventor and science administrator Vannevar Bush in his report Science: The Endless Frontier prepared in July 1945 for US President Harry Truman. In the report, he noted that the “social contract between science and society allows scientists alone to decide what research best serves the society.”
Having said that, the practice of science is never entirely free of politics. It makes its presence felt in science via money. While philanthropists and private foundations fund scientific research to some extent, most research is inherently shaped by the funding landscape of government, and therein lies the conflict between science and politics.
Since decisions about funding allocation are made by politicians, deciding what type of science a scientist should do is no longer a scientific one, but a political one. Furthermore, there are examples of politicians punishing or favouring scientists for ideological reasons. A case in point is Trofim Lysenko, a Russian agronomist and biologist, whose work was enthusiastically endorsed by the Soviet government under Stalin because his theories supported the principles of Marxism. Hence the term Lysenkoism, used to reference the manipulation of the scientific process to achieve ideological goals. On the other hand, the work of Andrei Sakharov, who holds an honoured place in the pantheon of distinguished physicists, was discredited by the Soviets because of his dissident humanitarian voice.
In the wake of the Covid-19 pandemic, which has so far claimed nearly 1.2 million lives worldwide, the relationship between science and politics is now smack at the centre of the world stage. While the world looked up to the United States to lead the fight against Covid-19, President Donald Trump, defying science, played down the severity of the virus by saying “It is what it is.” Not surprisingly, there is a surge of new cases in the USA, while leaders of countries who are carefully straddling the fine line between science and politics managed to contain the spread of the virus.
Regardless, scientists are working tirelessly to develop Covid-19 vaccines. Trials are underway, testing the BCG vaccine to see if it can provide at least temporary protection against the virus, marking the first time a vaccine is being tested against a specific pathogen other than the one it was designed for, which is tuberculosis. At the same time, researchers in the United Kingdom found that patients injected with T-cells, which are white blood cells that are of key importance to our immune system, responded positively to the Covid-19 virus.
Another example of the conflict between the value-laden space of political decision-making and the factual, objective world of science is climate change. Scientific evidence of climate change has helped to create a robust social and political debate about reducing greenhouse gas emissions. However, instead of responding positively to the debate, leaders of the fossil fuel producing countries are focusing on the uncertainties of climate models, or rejecting outright the findings of scientists, thereby sowing seeds of doubt about what constitutes “good” science.
Nevertheless, scientists are trying to convince politicians that it would serve all of us well if they use scientific facts as neutral information to guide public policy. Lest we forget, politicians need the knowledge that scientists possess in order to give us a decent shot at enjoying the full benefits of living in a high-tech world. Otherwise, they risk making ill-informed decisions on issues that are highly technical and complex.
Politics aside, scientific research and innovation are principally responsible for decades of economic growth and medical advances. Indeed, scientific discoveries, along with advanced techniques and instruments developed by scientists, particularly physicists, in the past 100 years or so have ushered in a new era in medical science.
The era began in 1895 with the discovery of X-ray, used today as a diagnostic tool to see through different parts of our body. Imaging by X-ray was dramatically improved after the invention of the computerised tomography. Other technologies, for instance nuclear magnetic resonance, are allowing us to recover from life-threatening illness which in the past would have been fatal. Additionally, positron emission tomography, or PET scan, developed after the discovery of positron—the anti-particle of an electron—allows doctors to check for diseases in our body, as well as help them to see how well our organs and tissues are working.
The advances in laser physics have also made considerable impact on medical research. Soon after the advent of lasers in 1960, they found their way into medical applications, namely ophthalmology, dermatology, cosmetic surgery, oncology, dentistry and more. More importantly, lasers allow surgeons to work at high levels of precision by focusing on a small area, damaging less of the surrounding tissues.
We could not do without radioactive materials in today’s world, even if we wanted to. Radioactive isotopes, discovered in the early 20th century, are an integral part of nuclear medicine and are commonly used to treat some cancers and medical conditions that require shrinking or destruction of harmful cells.
The use of nanotechnology in medical sciences is a rapidly expanding field. Originating from the Greek word nanos (dwarf), “nano” describes length scales of the order of a millionth of a millimetre. Although this field is still in its infant stage, there is a growing interest among the medical community to use the technology for targeted drug delivery, cancer treatment, nano-biosensors and nano-medical imaging.
The discovery of graphene in 2004 is among the highlights in materials science and nanotechnology. It is a sheet of carbon atoms just one atom thick, arranged in a honeycomb-like lattice with amazing physical and chemical properties. Graphene has potential applications in a wide range of areas of biomedical sciences. Chief among its applications is DNA sequencing, the gold standard for successful diagnosis of various diseases.
In 1938, when physicists successfully split (fission) the atomic nucleus, it gave humanity access to something extremely potent: the tremendous amount of energy released during the fission process. Immediately recognised as the basis for weapons of mass destruction, it is now used to generate around ten percent of the world’s electricity.
The letter “h” introduced by Max Planck in 1900 to explain the spectra of thermal radiation is the fundamental constant of quantum theory. Because this constant governs the scale of the quantum effects in the subatomic world, it had profound ramifications in technology. For example, it enabled the construction of microcircuits, quantum computers, transistors and semiconductors, lasers, iPods, cell phones and digital cameras that have changed the trajectory of our life from ordinary to extraordinary.
It is now almost impossible to get lost whether we are on land, sky or ocean, thanks to Einstein’s special and general relativity theories, which play a big role in the design of Global Positioning System satellites that give accurate readings of position, speed and direction of an object in real-time. The satellites would fail in their navigational functions if the relativistic effects of time dilation and spacetime curvature in their clocks are left uncompensated.
A final thought on the World Science Day for Peace and Development. In the past, scientists who challenged politicians for ignoring their advice have been accused of behaving unethically. But as we stare down the barrel of an ongoing global pandemic, we should realise that society forms politics, politics controls science and science inform both society and politics. So, as we move forward, a harmonious relationship between the three is ever more important in today’s fractious world.
