7 of the most popular science books of all time
A primer on the infinite of knowledge waiting to be learned.
- Chaos theory, evolution and the cosmos make for an eye-opening read.
- Carl Sagan paints a sagacious picture of humanity's place in the universe.
- Great scientists give us a glimpse into their minds and their theories.
Scientists have been sleuthing through the mysteries and secrets of the universe since humankind first started asking questions. Just what is going on in this grand amphitheater of reality? The courageous and curious sometimes leave their ivory towers to translate their arcane works into a more readable and digestible format.
Popular science books are an excellent way to get a grasp on a number of complex topics. They're also great starting points for people looking to dig deeper and learn more of the nitty gritty of the science itself. The wonders and observations from both inner and outer space and beyond is a clarion call for the reader that seeks to know more about how things work in the world.
From Charles Darwin to Stephen Hawking and more, these popular science books are guaranteed to open up new pathways of intellectual growth and curiosity.
A Brief History of Time
Stephen Hawking jokingly said that his book the Brief History of Time, is the least-read and most bought book ever. In it, Hawking set out to give a broad overview of what he knew and supposed to know in the wide realm of physics.
He goes on to explain the Big Bang and its connection to relativity, while also examining string theory — the idea that the universe is made up of some 10 or 26 dimensions. At some point in the book, he declares that intelligent beings can only exist during the expansion phase of a universe. Hawking makes this a thrilling read for the popular science book fan, as there isn't a single equation in sight.
On the Origin of Species
The first edition of Charles Darwin's seminal evolutionary book, The Origin of Species, was first published in 1859. For such a massive book and game changing scientific tome, it was actually written to be read by the general public.
The central thesis and without denial, fundamental fact of reality, evolution by natural selection remains one of the most important and mind-expanding discoveries we've ever realized. The beginning of the book sets the scene and slowly explains the basis of natural selection, at times it feels as if this could be found in a modern biology textbook.
This revolutionary idea is even more astounding when you realize that back in the 1800s, the concept of genetics didn't exist and there was no known science connecting the myriad of species together under one life-force. Darwin uncovered a fascinating and awe-inspiring fundamental fact of biology. It is so profound that geneticist Theodosius Dobzhansky famously once said, "Nothing in biology makes sense except in the light of evolution."
Pale Blue Dot: A Vision of the Human Future in Space
Carl Sagan, renowned science popularizer, sets out to explore our brief foray into the infinite. In this book, Sagan suggests that the human species and all of its biosphere's survival may depend on us spreading to the stars. Sagan seeks to show how the many scientific discoveries throughout the years has changed the perception we hold of ourselves and our place in the vast cosmos. It's worth excerpting Sagan's famous Pale Blue Dot quote in full, as he succinctly sums up how important cosmic perspective is for this little group of primates rotating together on this speck of blue:
"From this distant vantage point, the Earth might not seem of any particular interest. But for us, it's different. Consider again that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.
The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every 'superstar,' every 'supreme leader,' every saint and sinner in the history of our species lived there — on a mote of dust suspended in a sunbeam."
The Selfish Gene
Before Richard Dawkins was known as an dogmatic atheist, he wrote The Selfish Gene, which would turn out to be one of the first major popular science books. It's an incredibly poetic take on the subjects of genetics and evolution. Aside from Darwin, previous attempts to explain evolutionary processes and genetics had been largely academic and devoid of any popular understanding.
Dawkins manages to argue his idea that genes are the real drivers of evolution and a kind of immortality. To Dawkins, species and the individuals are mere vehicles for the gene, so they are in a sense just tools to propagate the gene. Before Dawkins put forth this idea, the general consensus was that natural selection hones its behavior in favor of keeping the individual creature or species alive. Try to take the idea metaphorically, as Dawkins' The Selfish Gene tends to border on the metaphysical at times.
Infinite in all Directions
Freeman Dyson has lived a long life as an incredible scientist. In Infinite in All Directions, Dyson's inquiries spread far and wide to the diversity of species on Earth to the infinitesimal workings of the universe and wonders about humanity's place in the cosmological scheme of things.
Originally presented as a sequence of lectures given in Scotland in 1985, the book does tend to reference some events of the time. Most of the topics from the lecture have been reworked into book form and cover a wide breadth of disciplines. Dyson gives a special dissertative focus on nuclear disarmament as well.
Chaos: Making a New Science
James Gleick gives a cursory introduction on the actual science of chaos. After that he goes on to account for the many scientists who laid the foundation for this science. Their trials and tribulations make up the majority of this book.
Gleick manages to convey an interesting aspect of chaos theory that serves as a gateway to more advanced topics and possibly a meandering walk into game theory. The main idea is as follows: the most innocuous and minute change in initial conditions will lead to unpredictable if not drastic changes in the later output. An example of this is the oft repeated Butterfly Effect, where the flapping of a butterfly's wings could go on to cause a storm some few thousand miles away. Chaos theory is in a sense an all-encompassing aspect of anything in existence and so touches everything from mathematics, biology and to even manmade ideals, such as finance or economics.
The Structure of Scientific Revolutions
Thomas Kuhn sought to change the cliched perspective of the diligent scientist slowly working with his bin of unquestionable facts, hypothesizing, experimenting, accumulating knowledge in incremental steps and then… aha! Discovery. No, the structures of scientific revolution doesn't come from the status quo set of accepted scientism caste book — they emerge from what Kuhn calls a paradigm.
A paradigm is a cultural and scientific communally accepted background all scientists adhere to. It is a set of assumptions, theories, and biases in which all new scientific evidence must first pass through before new discoveries are reworked into new hypotheses about reality. Kuhn believed that what we call science is just "filling in the details," after a paradigm has been set.
Kuhn challenges the concept of scientific process and considers it rather to be a shift of paradigms in which we radically change our view of the world. Think for example, the Copernican revolution, Einstein's theories or quantum physics. After enough time, the paradigm will play out to its final conclusion before being disregarded for a newer and more comprehensive paradigm — that one, too, is liable to one day be usurped by more compelling arguments.

The COVID-19 pandemic is making health disparities in the United States crystal clear. It is a clarion call for health care systems to double their efforts in vulnerable communities.
- The COVID-19 pandemic has exacerbated America's health disparities, widening the divide between the haves and have nots.
- Studies show disparities in wealth, race, and online access have disproportionately harmed underserved U.S. communities during the pandemic.
- To begin curing this social aliment, health systems like Northwell Health are establishing relationships of trust in these communities so that the post-COVID world looks different than the pre-COVID one.
COVID-19 deepens U.S. health disparities<p>Communities on the pernicious side of America's health disparities have their unique histories, environments, and social structures. They are spread across the United States, but they all have one thing in common.</p><p>"There is one common divide in American communities, and that is poverty," said <a href="https://www.northwell.edu/about/leadership/debbie-salas-lopez" target="_blank">Debbie Salas-Lopez, MD, MPH</a>, senior vice president of community and population health at Northwell Health. "That is the undercurrent that manifests poor health, poor health outcomes, or poor health prognoses for future wellbeing."</p><p>Social determinants have far-reaching effects on health, and poor communities have unfavorable social determinants. To pick one of many examples, <a href="https://www.npr.org/2020/09/27/913612554/a-crisis-within-a-crisis-food-insecurity-and-covid-19" target="_blank" rel="noopener noreferrer">food insecurity</a> reduces access to quality food, leading to poor health and communal endemics of chronic medical conditions. The U.S. Centers for Disease Control and Prevention has identified some of these conditions, such as obesity and Type 2 diabetes, as increasing the risk of developing a severe case of coronavirus.</p><p>The pandemic didn't create poverty or food insecurity, but it exacerbated both, and the results have been catastrophic. A study published this summer in the <em><a href="https://link.springer.com/article/10.1007/s11606-020-05971-3" target="_blank">Journal of General Internal Medicine</a></em> suggested that "social factors such as income inequality may explain why some parts of the USA are hit harder by the COVID-19 pandemic than others."</p><p>That's not to say better-off families in the U.S. weren't harmed. A <a href="https://voxeu.org/article/poverty-inequality-and-covid-19-us" target="_blank" rel="noopener noreferrer">paper from the Centre for Economic Policy Research</a> noted that families in counties with a higher median income experienced adjustment costs associated with the pandemic—for example, lowering income-earning interactions to align with social distancing policies. However, the paper found that the costs of social distancing were much greater for poorer families, who cannot easily alter their living circumstances, which often include more individuals living in one home and a reliance on mass transit to reach work and grocery stores. They are also disproportionately represented in essential jobs, such as retail, transportation, and health care, where maintaining physical distance can be all but impossible.</p><p>The paper also cited a positive correlation between higher income inequality and higher rates of coronavirus infection. "Our interpretation is that poorer people are less able to protect themselves, which leads them to different choices—they face a steeper trade-off between their health and their economic welfare in the context of the threats posed by COVID-19," the authors wrote.</p><p>"There are so many pandemics that this pandemic has exacerbated," Dr. Salas-Lopez noted.</p><p>One example is the health-wealth gap. The mental stressors of maintaining a low socioeconomic status, especially in the face of extreme affluence, can have a physically degrading impact on health. <a href="https://www.scientificamerican.com/index.cfm/_api/render/file/?method=inline&fileID=123ECD96-EF81-46F6-983D2AE9A45FA354" target="_blank" rel="noopener noreferrer">Writing on this gap</a>, Robert Sapolsky, professor of biology and neurology at Stanford University, notes that socioeconomic stressors can increase blood pressure, reduce insulin response, increase chronic inflammation, and impair the prefrontal cortex and other brain functions through anxiety, depression, and cognitive load. </p><p>"Thus, from the macro level of entire body systems to the micro level of individual chromosomes, poverty finds a way to produce wear and tear," Sapolsky writes. "It is outrageous that if children are born into the wrong family, they will be predisposed toward poor health by the time they start to learn the alphabet."</p>Research on the economic and mental health fallout of COVID-19 is showing two things: That unemployment is hitting <a href="https://www.pewsocialtrends.org/2020/09/24/economic-fallout-from-covid-19-continues-to-hit-lower-income-americans-the-hardest/" target="_blank" rel="noopener noreferrer">low-income and young Americans</a> most during the pandemic, potentially widening the health-wealth gap further; and that the pandemic not only exacerbates mental health stressors, but is doing so at clinically relevant levels. As <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7413844/" target="_blank" rel="noopener noreferrer">the authors of one review</a> wrote, the pandemic's effects on mental health is itself an international public health priority.

Credit: Northwell Health<p>Novel coronavirus may spread and infect indiscriminately, but pre-existing conditions, environmental stressors, and a lack of access to care and resources increase the risk of infection. These social determinants make the pandemic more dangerous, and erode communities' and families' abilities to heal from health crises that pre-date the pandemic.</p><p>How do we eliminate these divides? Dr. Salas-Lopez says the first step is recognition. "We have to open our eyes to see the suffering around us," she said. "Northwell has not shied away from that."</p><p>"We are steadfast in improving health outcomes for our vulnerable and underrepresented communities that have suffered because of the prevalence of chronic disease, a problem that led to the disproportionately higher death rate among African-Americans and Latinos during the COVID-19 pandemic," said Michael Dowling, Northwell's president and CEO. "We are committed to using every tool at our disposal—as a provider of health care, employer, purchaser and investor—to combat disparities and ensure the <a href="https://www.northwell.edu/education-and-resources/community-engagement/center-for-equity-of-care" target="_blank" rel="noopener noreferrer">equity of care</a> that everyone deserves." </p><p>With the need recognized, Dr. Salas-Lopez calls for health care systems to travel upstream and be proactive in those hard-hit communities. This requires health care systems to play a strong role, but not a unilateral one. They must build <a href="https://www.northwell.edu/news/insights/faith-based-leaders-are-the-key-to-improving-community-health" target="_blank" rel="noopener noreferrer">partnerships with leaders in those communities</a> and utilize those to ensure relationships last beyond the current crisis. </p><p>"We must meet with community leaders and talk to them to get their perspective on what they believe the community needs are and should be for the future. Together, we can co-create a plan to measurably improve [community] health and also to be ready for whatever comes next," she said.</p><p>Northwell has built relationships with local faith-based and community organizations in underserved communities of color. Those partnerships enabled Northwell to test more than 65,000 people across the metro New York region. The health system also offered education on coronavirus and precautions to curb its spread.</p><p>These initiatives began the process of building trust—trust that Northwell has counted on to return to these communities to administer flu vaccines to prepare for what experts fear may be a difficult flu season.</p><p>While Northwell has begun building bridges across the divides of the New York area, much will still need to be done to cure U.S. health care overall. There is hope that the COVID pandemic will awaken us to the deep disparities in the US.</p><p>"COVID has changed our world. We have to seize this opportunity, this pandemic, this crisis to do better," Dr. Salas-Lopez said. "Provide better care. Provide better health. Be better partners. Be better community citizens. And treat each other with respect and dignity.</p><p>"We need to find ways to unify this country because we're all human beings. We're all created equal, and we believe that health is one of those important rights."</p>
With just a few strategical tweaks, the Nazis could have won one of World War II's most decisive battles.
- The Battle of Britain is widely recognized as one of the most significant battles that occurred during World War II. It marked the first major victory of the Allied forces and shifted the tide of the war.
- Historians, however, have long debated the deciding factor in the British victory and German defeat.
- A new mathematical model took into account numerous alternative tactics that the German's could have made and found that just two tweaks stood between them and victory over Britain.
Two strategic blunders<p>Now, historians and mathematicians from York St. John University have collaborated to produce <a href="http://www-users.york.ac.uk/~nm15/bootstrapBoB%20AAMS.docx" target="_blank">a statistical model (docx download)</a> capable of calculating what the likely outcomes of the Battle of Britain would have been had the circumstances been different. </p><p>Would the German war effort have fared better had they not bombed Britain at all? What if Hitler had begun his bombing campaign earlier, even by just a few weeks? What if they had focused their targets on RAF airfields for the entire course of the battle? Using a statistical technique called weighted bootstrapping, the researchers studied these and other alternatives.</p><p>"The weighted bootstrap technique allowed us to model alternative campaigns in which the Luftwaffe prolongs or contracts the different phases of the battle and varies its targets," said co-author Dr. Jaime Wood in a <a href="https://www.york.ac.uk/news-and-events/news/2020/research/mathematicians-battle-britain-what-if-scenarios/" target="_blank">statement</a>. Based on the different strategic decisions that the German forces could have made, the researchers' model enabled them to predict the likelihood that the events of a given day of fighting would or would not occur.</p><p>"The Luftwaffe would only have been able to make the necessary bases in France available to launch an air attack on Britain in June at the earliest, so our alternative campaign brings forward the air campaign by three weeks," continued Wood. "We tested the impact of this and the other counterfactuals by varying the probabilities with which we choose individual days."</p><p>Ultimately, two strategic tweaks shifted the odds significantly towards the Germans' favor. Had the German forces started their campaign earlier in the year and had they consistently targeted RAF airfields, an Allied victory would have been extremely unlikely.</p><p>Say the odds of a British victory in the real-world Battle of Britain stood at 50-50 (there's no real way of knowing what the actual odds are, so we'll just have to select an arbitrary figure). If this were the case, changing the start date of the campaign and focusing only on airfields would have reduced British chances at victory to just 10 percent. Even if a British victory stood at 98 percent, these changes would have cut them down to just 34 percent.</p>
A tool for understanding history<p>This technique, said co-author Niall Mackay, "demonstrates just how finely-balanced the outcomes of some of the biggest moments of history were. Even when we use the actual days' events of the battle, make a small change of timing or emphasis to the arrangement of those days and things might have turned out very differently."</p><p>The researchers also claimed that their technique could be applied to other uncertain historical events. "Weighted bootstrapping can provide a natural and intuitive tool for historians to investigate unrealized possibilities, informing historical controversies and debates," said Mackay.</p><p>Using this technique, researchers can evaluate other what-ifs and gain insight into how differently influential events could have turned out if only the slightest things had changed. For now, at least, we can all be thankful that Hitler underestimated Britain's grit.</p>
The next era in American history can look entirely different. It's up to us to choose.
- The timeline of America post-WWII can be divided into two eras, according to author and law professor Ganesh Sitaraman: the liberal era which ran through the 1970s, and the current neoliberal era which began in the early 1980s. The latter promised a "more free society," but what we got instead was more inequality, less opportunity, and greater market consolidation.
- "We've lived through a neoliberal era for the last 40 years, and that era is coming to an end," Sitaraman says, adding that the ideas and policies that defined the period are being challenged on various levels.
- What comes next depends on if we take a proactive and democratic approach to shaping the economy, or if we simply react to and "deal with" market outcomes.
