Thoughts about Science and COVID-19

I’ve written about science for many years, mostly space and astronomy topics. It’s actually quite satisfying to do this work. I get notices of people’s scientific accomplishments, and I get to tell their stories. It is, after all, people doing science. It just doesn’t do itself. The planets and stars and galaxies will continue to do their thing. Our observations of those objects and their activities will help us understand them. Same with any other science.

Science is a process of discovery. It doesn’t stop at one “aha!” moment. Science discovery continues from one moment to the next, as new data comes in. Data points are the core of science. Gather enough data and you have something to talk about, to make models of, to construct theories and rules about what you have observed. That’s the way science works.

So, for example, in the current pandemic crisis, what science can do is gather data points about rates of infection. That information is gold because it helps us do more to help prevent the spread of the disease and help those who have it. We can also learn how to avoid getting it based on data.

For this one, researchers need a LOT of information. They can use data from places where the infection rate is rising or falling. They need information about who is affected and how it was spread. Scientists can look at who survives and who doesn’t, and what measures were taken to help the survivors. Researchers also need data about populations and relative rates of infection over time. And, they can use this and other information to figure out how best to treat it, where to send much-needed medical equipment, and so on.

Oh, and they can work toward creating a usable vaccine. That seems pretty straightforward. And, that’s how it should work.

Science Denialism

There are people in the world who don’t like science. They fear it. Or they fear what it might tell them. Or they fear what it might say about their political “leadership”. So, they deny it. Or they threaten the scientists doing the work of understanding things.

In most cases, people deny facts that are clearly right in front of them. We are seeing a lot of that today, with the spread of the SARS-CoV-2 virus and the COVID-19 epidemic it is causing. In addition to the truly silly conspiracy theories about the sickness, there are people who are spinning data points out of context, or simply not collecting or reporting data at all.

There are likely political reasons behind the slow reporting of infections. However, there are also some practical reasons and those need to be overcome. One of the biggest issues is that there aren’t enough tests being made available in the U.S. to definitively test everyone who may have the virus.

Another obstacle: not everyone who has the virus shows symptoms. As in any other science, medical people have to have actual examples of the subject in front of them. In medicine, someone with symptoms gives them information. Someone without any symptoms isn’t going to present themselves. And, thus, medical researchers and doctors can’t even begin to consider if someone has the virus or not.

In addition, folks without symptoms have no way of knowing that they do have it. That also contributes to a lack of data. And, strong science requires strong data points. Science about this virus and its effects needs better reporting. That’s a fact. It will help people learn WHY social distancing is so important, why staying home and following cleanliness guidelines may help save their lives or the life of a loved one.

I hope that more data will be reported. As doctors and others get a handle on the many side effects of this virus, how the illness it causes presents itself, and other aspects of the epidemic, I want to see them get what they need to know. It’s the only way to understand this particular pandemic.


Just the Facts, Please

We all should hope that medical science gets what it needs. Our lives depend on it. Our societies can’t function without more information. Scientists can’t make headway on understanding this illness or the virus without information. Worldwide honest reporting of data is important. This isn’t the time for political posturing or national pride that might prevent accurate numbers from getting out. Just the facts: they are the heart of science.

The Stars and Planets Ignite Our Dreams

And Make Us Think About What is Possible

What price do you put on stimulating the imagination and scientific interest in someone? I don’t know about you, but I think it’s priceless. Certain events in our history are enough to get us dreaming about the infinite possibilities that lie out there among the other planets and the distant stars and galaxies. Or course, those events did cost something in terms of money and human effort. There’s always a price, a cost, a tradeoff. The payback is knowledge, which comes with both costs, plus the chance to look at places we’ve never seen before. That’s the essence of exploration.

New Horizons cost around $700 million, and has certainly inspired people around the world. Worth it? I’d say so. We are supposed to be learning about our universe, using the brains and intellect that evolved along with our bodies. This mission just showed us a world that was long seen only as a point of light. It’s now a place with mountains and craters and icy “continents”, and a “plasma tail’ and a thin atmosphere, and a slew of moons.

Of course, many people have been celebrating the Apollo 11 landings and the first people to walk on the Moon. The entire Apollo program cost around $25 billion, and its scientific and cultural returns are priceless. We ALL learned something about the Moon, just as we’re all learning something about Pluto with New Horizons. And, about Mars with the missions there. And, about the other planets of the solar system from the many spacecraft we’ve sent out.

We live in an evolving solar system. It hasn’t stopped changing since its formation some 4.5 billion years ago. We’re part of the system, and only recently have we learned to look with scientific eyes at the places that exist in our little part of the galaxy. We’ve learned amazing things through our explorations using both ground-based and space-based instruments. And there’s more out there, if we’re not afraid to go for it.

Is knowing what we know about the solar system and the rest of the universe worth less than the cost of a football stadium? Is it worth less to you personally than the cost of a boutique coffee or a slice of pizza? Is it less important than buying a senator or a whole roomful of them at bargain basement prices? What price do you put on integrity and honesty, scientific curiosity, the urge to KNOW how all this universe works?

You know what MY answer is. Spending money on such exploration benefits people; it creates jobs, stimulates economies and careers, at the same time it teaches us our place in the cosmos. I’d say we got a hell of a deal when we started sending spacecraft out to explore the cosmos. They’re part of us, they’re our eyes and ears on the cosmos, and they are showing us what the universe is made of. Pretty darned good expenditure and use of our time, talents, and energies.

What will we explore next? Exoplanets? There’s more news about those coming soon. How about distant galaxies born in the fires of the first half billion years of the cosmos? Coming up with James Webb Space Telescope. Want to know more about the first stars? Our multi-wavelength observatories in space and on the ground are on the case. Each one of those projects is made up of equipment, sure. But, it’s the people who do the hard work of building, testing, thinking, and sharing the universe with the rest of us. THAT should be worth something to you as you gaze at the stars, look at the pretty pictures, and dream of exploring the cosmos. Shouldn’t it?
