No, life has not yet been found on Mars, but imagine waking up to that headline. How would you react? The headline’s font would be huge on print newspapers—maybe one word per page, occupying the first four pages. Some bold papers might even put one letter per page and go so far as to have blank pages for the spaces. The point is, it would be big news.
So I ask again, what would this stir for you?
For me, the swirl would be thick with competing thoughts and feelings, tripping over themselves to get out. First would be the raft of questions stemming from pure curiosity. Is it DNA-based? Is it a separate start, or do we share some ancient microbial ancestor—possibly shuttled from one body to the other following a meteoric impact? What lessons can we learn about how life forms? Can we get the discovered lifeforms to call us Mama or Dada? Will they make good pets?
One can imagine the discovery team, whether at NASA or elsewhere, ecstatic with joy. The entire exploration establishment around the planet would likely be giddy. SETI folks would probably be unable to chew for a while, wearing fixed grins.
I would share many of these same reactions, for the pure joy of discovery and the novel opportunity to re-examine what it means to be a part of life on Earth. But then it dawns on me just how devastating the news might actually be for the human race.
The cessation of regular blog posts has prompted a number of folks to ask if I still live and breathe. Several reasons contribute to the silence. Primarily, most of what I set out to do and say on Do the Math has been covered. How many times can I calculate total tidal power available? I’ve expressed views on our precarious trajectory with respect to finite resources, touched on the psychology of major change and sacrifice, and shared personal explorations in reducing energy/resource footprints at home. While some of this continues (look for a post on nickel-iron batteries soon), for the most part it’s already all there.
The second factor is that the research, education, and administration components of my life (i.e., my job) are demanding significant attention. This has generally been true all along, but the administrative burden has skyrocketed of late due to my role as vice chair of the physics department at UCSD since July 2013. Perhaps as I climb up the learning curve, I’ll find more “hobby” time in the months ahead.
While I am sharing personal news, two things of note: 1) My efforts to write and speak about energy and resource use to a broad audience has resulted in UCSD awarding me the Outstanding Faculty Sustainability Award for 2014. This despite the fact that I don’t know what sustainability means (suspecting that none of us really do), and that very little of my efforts have been directed at the UCSD campus. All the same, I am as pleased as I am surprised by the recognition. 2) While not related to Do the Math, I encourage you to check out this stunning photo taken by Dan Long capturing our recent laser ranging efforts during the April 15 lunar eclipse. This is a real photo, taken through a C-11 telescope with a focal reducer (700 mm, f/2)—the outgoing laser beam has not been artificially superimposed. Normally it is really difficult to get a picture of our faint beam heading toward the Moon, because the Moon is so glaringly bright. The eclipse provided a great photo-op, and also a means to test the hypothesis of dusty reflectors. To me, this shot is just gorgeous. But I have more invested in it than the average Joe: this picture serves as a visual representation of a key focus in my life over the last 14 years—so of course I’m enamored.
The futuristic survey (covered in last post) has attracted about 1300 respondents, 900 from DtM, 300 from the Energy Bulletin (now Resilience.org), and a smattering from other places.
I will ultimately be sharing the results, but the habitual readers of the aforementioned sites are perhaps not representative of the population at large.
Thus I would like your help in pushing this out to a broader population. See if you can get your friends and family members to take the survey, and perhaps even pass the link on to their friends, etc. I’ve never done this sort of thing before, so do not know what to expect. But let’s give it a try, yeah?
Here’s the link you want to pass on in whatever form (paste into e-mail, Twitter, link on FaceBook, whatever works): https://www.surveymonkey.com/s/2ZC6RD9
Thanks for your help—should be very interesting.
One day, sitting around with a group of undergraduate physics students, I listened as one made the bold statement: “If it can be imagined, it can be done.” The others nodded in agreement. It sounded like wisdom. It took me all of two seconds to violate this dictum as I imagined myself jumping straight up to the Moon. I may have asked if the student really thought what he said was true, but resisted the impulse to turn it into an impromptu teaching moment. Instead, I wondered how pervasive this attitude was among physics students and faculty. So I put together a survey and in this post report what I found. The overriding theme: experts say don’t count on a Star Trek future. Ever.
Putting on my astronomer hat, as one whose main research focus involves measuring the distance between the Earth and Moon, I feel compelled to “speak out” about the “supermoon” hype that crops up periodically.
Last night’s full moon was touted to be a “supermoon”—larger than normal. As a result, many folks made it a point to watch the Moon rise. I love the fact that people are paying attention to the Moon, getting outside, and enjoying the serene experience of watching the Moon creep over the horizon. What I don’t like is that the hype leads to an overall sense of disappointment in many. Is the campaign a net positive, or a net negative? I don’t know.
In this post, we’ll look at the numbers and see just how special the supermoon is.
