The scientific mysteries that led to Einstein’s E=mc^2 equation

Scientists deal with mysteries. As Richard Feynman once commented:  “Science must remain a continual dialog between skeptical inquiry and a sense of inexplicable mystery”.Three examples: it is profoundly mysterious as to why mathematics can so accurately describe our physical world, and even predict events, such as the motion of the planets or the propagation of radio waves from earth to spacecraft.  The theorems of mathematics are not normally thought to derive from properties of the real world...

Is motion an illusion of the senses?

According to Aristotle, Zeno of Elea (ca. 490 – ca. 430 BCE) said, “Nothing moves because what is traveling must first reach the half-way point before it reaches the end.”One interpretation of the paradox is this. To begin a trip of a certain distance (say 1 meter), a traveler must travel the first half of it (the first 1/2 m), but before he does that he must travel half of the first half (1/4 m), and in fact half of that (1/8 m), ad infinitum. Since there will always exist a smaller first half ...

Accept death to promote health

We all die and, despite some fanciful ideas to the contrary, we will, as a species, continue to do so. Our daily routines tend to distract us from this fact. However, because death is inevitable, we need to think about how we can live healthy lives, without ignoring how they end.Once we accept that we are going to die, how we spend our money and our time on health begins to shift. At core, we should aspire to die healthy. That means focusing our energy on creating a world that maximizes health r...

There’s no vaccine for the sea level rising

We will get by the current pandemic. There will be a vaccine eventually. There will be other pandemics. Hopefully, we will be better organized next time.Waiting in the wings are the emerging impacts of climate change, the next big challenge. There will be no vaccine to stem sea level rise. We will first lose Miami (highest elevation of 24 feet), London (36 feet), Barcelona (39 feet) and New Orleans (43 feet).  Paris and New York City will disappear a bit later.There are estimates that the cost o...

How understanding science can be made easy

When I was a teenager, I was awed by popular science writings. I was most affected by Roger Penrose’s The Emperor’s New Mind, with its detailed and fascinating account of quantum mechanics and relativity. However, it was not an easy read and it gave only one perspective of these amazing theories.Some 30 years later one of my mentors has given me advice on what to tell my students when things get tough: “Science is hard.” He meant that doing good science is hard. You must be meticulous in your fo...

Accepting uncertainty creates freedom

We all want to be in control.Our quest for control in the current atmosphere of fear has resulted in the hoarding of toilet paper, hand sanitizer, and face masks. In the illusion of control, we close our minds and our hearts to the possibility of the meaning we may discover during a time of crisis. Ironically, the very security we struggle to find becomes a wall that we build around ourselves, quarantined in terror. The most dangerous isolation is not the necessary reality of the precautions bei...

Income inequality drives health disparities

Pretax incomes for the poorest 50% of Americans have stayed mostly unchanged for the past 40  years, widening income gaps in the country. We leave the question of why inequality matters for the economy to others. What is of concern to us is whether income inequality matters to our health, and, to the extent that it does, how the health profession should respond.In 1992, Richard Wilkinson, then a professor at the University of Sussex, published a paper in The British Medical Journal called “Incom...

Understanding quantum mechanics [quiz]

Mechanics is that part of physics concerned with stuff that moves, from cannonballs to tennis balls, cars, rockets, and planets. Quantum mechanics is that part of physics which describes the motions of objects at molecular, atomic, and sub-atomic levels, such as photons and electrons.Although quantum mechanics is an extraordinarily successful scientific theory, on which much of today’s tech-obsessed lifestyles depend, it is also completely mad. The theory quite obviously works, but it appears to...

How an unlikely pair became legendary molecular biologists

In 1962 the Nobel Prize in chemistry was awarded jointly to John Kendrew (1917-1997) and Max Perutz (1914-2002). They were the first scientists to accurately describe the three-dimensional structure of proteins. Enzymes, hormones, and antibodies are only a few examples of the many kinds of proteins present in all living organisms and knowledge of their structure is essential for progress in curing human diseases. Consequently, Kendrew and Perutz have become legendary scientists whose research is...

The emotional toll of the COVID-19 pandemic on teenagers

A growing body of evidence supports my clinical experience that younger people, high schoolers especially, are having more psychological problems during the pandemic than adults. There are many reasons for this. Adolescents are in the developmental stage of forming a new social world away from their parents. Social needs tend to dominate their lives and yet currently this growth has come to a bit of a standstill. In addition, teenagers are not fully cognitively developed; their moods still domin...

Why politics is so polarized, even though Americans agree on most key issues

In 1971, Jerry B. Harvey created “The Abilene Paradox” to describe a pernicious failure: mismanagement of agreement. The late professor and management consultant posited that “the inability to cope with agreement, rather than the inability to cope with conflict, is the single most pressing issue of modern organizations.”“Getting on the bus to Abilene,” as Harvey later called it, is taking a trip with fellow passengers who willingly get on a bus headed off to somewhere none of them want to go.The...

Seven ways to talk to terminal patients

Before COVID-19 arrived in our lives, chronic illness was considered the next worldwide pandemic. But COVID-19 did arrive and life as we knew it has radically changed. Healthcare workers, particularly nurses and physicians, are now having frequent palliative care (the area of end-of-life care that focuses on patient comfort) conversations although most are not trained as palliative care specialists.The prolific use of telehealth has also placed a demand on all healthcare providers to rely on com...

Six ways to reduce your environmental impact

Over the last 50 years, human population has doubled, and global trade has increased ten-fold, drawing more deeply on Earth’s natural resources, warming the climate, and polluting the global environment. If current climate trends continue, a third of the global population will live in places warmer than the heart of the Sahara Desert 50 years from now. Given the likely migration response to these and other changes, today’s youth will likely experience massive environmental and societal shocks du...

How anti-immigration policies hurt public health

Immigration is neither a new issue nor an exclusively American one. In 2017, there were more than 250  million immigrants living worldwide, and about 2.4 million people migrate across national borders each year. Migration also occurs within national borders—it is estimated that more than 750 million people live within their country of birth, but in a different region. Economic, political, and social forces drive migration. Migrants who are forced to leave their country due to war or persecution ...

What history can tell us about infectious diseases

One of the remarkable achievements of the past hundred years has been the reduction of the global toll of death from infectious disease. The combination of applied biological science, improved living and working conditions, and standards of living, together with the benefits of planned parenthood, have transformed the health landscape for millions of people, not least in the developed world. Unfortunately, this led to the belief that these developments had led to the disappearance of infectious ...

How after school music programs have adapted to online music playing

“OrchKids is working hard to stay ahead of the curve!” That’s the message delivered this spring to friends and supporters of OrchKids, a free after-school music instruction program for more than 2,000 Baltimore students, pre-K through high school. In March 2020, OrchKids staff had to totally change their way of teaching. The public schools where they held their group classes shut down abruptly, because of a government mandate aimed at slowing the spread of the COVID-19 pandemic.OrchKids educator...

Moving beyond toxic masculinity: a Q&A with Ronald Levant

In 2018, the American Psychological Association released its first ever Guidelines for Psychological Practice with Boys and Men. At the time of the release, these guidelines were met with criticism by some who viewed them as pathologizing masculinity, but since the guidelines were released the discussion of “toxic masculinity” has spread to all areas of our society and culture. Ronald F. Levant has served as president of American Psychological Association as well as president of the association’...

Should we fear death?

We are currently faced with a global crisis. A virus has spread to all parts of our planet, and thousands of people have died from the coronavirus. Many people now fear that they are going to be sick and die. Fear of sickness can certainly be rational. It is more questionable whether fear of death is so. Death is something we mourn or fear as the worst thing that could happen. And yet being dead is something that no one can experience and live to describe.There is the process of dying, the incid...

How conspiracy theories hurt vaccination numbers

Near the end of 2018, data released by the Centers for Disease Control and Prevention showed that a small, but growing, number of children in the United States were not getting recommended vaccinations. One in 77 infants born in 2017 did not receive any vaccination. That’s more than four times as many unvaccinated children as the country had at the turn of the century. Some of this may be due to lack of access to vaccines; populations without insurance and those living in rural areas have greate...

Why anti-vaxxers are rising again

In the midst of a health crisis when our only hope is a new vaccine, many have begun to wonder how those with anti-vaccination sentiments might respond to the current COVID-19 crisis. Many have guessed that the only natural, rational response would be for anti-vaxxers to change their minds and wholeheartedly embrace the prospect of a new vaccine. After all, there is a prevailing theory that anti-vaccine sentiment arises at least in part from a collective amnesia about the true scourge of vaccine...

Pandemic practicalities and how to help teenagers manage time at home

It’s May and many of us have fond memories of springtime when we were in high school. There was some stress from exams and final papers to be sure, but also more outdoor activities, sports, banquets or awards assemblies, proms, and most of all, looking forward to the summer. High school students today, however, have lost all of that. Seemingly in an instant, they are confined at home, with little access to friends, no organized sports, arts, music, journalism, or other activities. Education via ...

How to prepare for death

The main challenge in reflecting on one’s own death is the way the various aspects of death and dying are intertwined which make it difficult to discern personal mortality.First there is the prospect of me dying; of me entering whatever is in store at the end of my life. How long will it last? Will there be pain? What will I leave behind? How do I say goodbye? Next there is the prospect of other people dying, particularly the death of loved-ones and the painful absence their loss leaves behind. ...

Quantitative thinking during a pandemic

Today is not right. The weather is fine. My family and friends are healthy and waiting to hear from me, ready for ordinary things like coffee and conversation. Normally, I’d be taking my grandkids to daycare and checking up on grocery and laundry lists. Then, a bit of reading and some writing. But, instead of my usual activity I sit alone in a world of similars. No driving grandkids to school, no personal contact, no “I’ll-pick-it-up-when-next-I’m-at-the-store.” How peculiar this sudden-forced l...

Is collecting medical data really essential for health care?

The United States spends an inordinate amount of money on health care. Much of this spending goes to data acquisition, to medical monitoring, and to assessment of how our health systems function. But are there other areas where money devoted to gathering health data might be better spent?Our health is a product of the world around us. This is perhaps most easily understood by thinking about how much time we spend in the various places where we live, work, and gather.Data from the Bureau of Labor...

Understanding guilt in mother-child relationships

“You never write…you never call….” The guilt-tripping mother is common stereotype in movies and TV. But how many adult children harbor feelings of guilt toward their aging parents? Who experiences this guilt, and why?About one in five adult children experience feelings of guilt toward their ageing mothers, based on data from a nationally representative survey of 2,450 Dutch adults in 2015 who have a mother aged 55 or older. Feelings of guilt in the family have rarely been measured in a systemati...

Confronting mortality in the COVID-19 pandemic

In the last four months, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has marched across the globe. It has stomped to every continent and, as of my writing, to 134 of the 195 countries in the world, sickening hundreds of thousands of people – and killing thousands of them – on its way to global dominance.Recently the New York Times ran a story about a doctor and a nurse, both women in their mid-twenties, each with a loving partner and a young child, who, in the hospitals of W...

Music schools respond to COVID-19 shutdown

Keeping Upbeat in Tough Times is the new motto for the San Francisco Community Music Center. The phrase sums up the school’s attitude toward the abrupt transition to online instruction that it had to make this spring, after local schools closed their doors because of a government-ordered mandate aimed at slowing the spread of the COVID-19 pandemic. Teachers at music schools have done their best to adjust to virtual teaching. “I’m trying to think about it as positively as possible,” said Peabody ...

Why the COVID-19 pandemic feels like a movie

I read there is a spike in streaming of the 2011 film Contagion by Steven Soderbergh. The film uses a made-up virus loosely modeled after a Nipah virus outbreak. Contagion opens with a black screen, and we hear a woman coughing. The fictional virus MEV-1 hits the brain (and not the lungs as in corona virus pandemics), and we see deadly seizures and exposed brains with surprised pathologists. In Contagion the virus spreads quickly across the globe and kills its victims via a simple chain of germs...
