Life of Science Writer Delia Godding Highlighted in Upcoming Lecture

Reconstructing the important historical contributions of women to science has been a passion of CCSU astronomy professor Dr. Kristine Larsen for several decades. In her 2017 book The Women Who Popularized Geology in the 1800s she focused on women who wrote popularized works on geology for an audience of women and children. On Sunday, April 29 at 9:30 AM she will give a free public talk on one of these woman, Delia Godding, at St. John’s Church in West Hartford. Delia taught at the school associated with this church for several years, so it is good to see her memory returning home.

Don’t be afraid of Friday the 13th!

friday-the-13th-the-game-828236

Okay, maybe you can be a little afraid of Jason, but the day Friday the 13th is no scarier than any other. Fear of this day (called paraskevidekatriaphobia) has its roots in legend and superstition. While there is nothing truly unlucky about this day in particular, it does create some interesting trends in human behavior, as people try to avoid the supposed bad luck associated with it. The most superstitious among us stay home, resulting in millions of dollars in lose sales in stores, restaurants, and other businesses. On the other hand, this lightens the traffic on our roads, and at least one study ties superstitions about Friday the 13th to a reduction in traffic accidents on this day.

Just like superstitions concerning eclipses and moon phases (there really aren’t more admissions to hospitals on full moons!), superstitions concerning Friday the 13th don’t stand up in the face of facts.

The Universe Loses a Brilliant Star: Stephen Hawking

nasa-can-stop-looking-for-black-holes-says-stephen-hawking-2

Stephen Hawking wrote that the boundary condition of the universe is that it has no boundary. The same can certainly be said of his influence on our world. This goes far beyond his direct scientific legacy, his ground-breaking research into black holes. In the 1970s he predicted that black holes aren’t always strictly “black;” instead, under the right conditions they can “evaporate” away, a process known as Hawking radiation. In particular, minuscule subatomic beasties called primordial black holes were predicted by Hawking to have been associated with the birth of our universe, and observations of their tell-tale final explosions in a shower of gamma rays have been sought for many years.

But Hawking’s influence certainly transcends his equations and his scientific papers. In the mid-1980s, Hawking decided to tackle an equally difficult task, to pen a book on theoretical physics for a popular audience. The result, A Brief History of Time, sold more than 10 million copies, although he himself admitted that a significant number of copies were never read from start to finish.

Hawking’s ability to motivate the general public to attempt to understand the mind-bending marvel that is our universe is arguably his most important contribution to science. For as his readers struggled to understand singularities and boundary conditions, event horizons and virtual particles, even at this so-called nontechnical level, they were mirroring the very same process that scientists go through every single day as they strive to understand reality. In this way, Hawking made science “real” even while trying to describe the properties of so-called imaginary time.

It is unknown how many of the upcoming generation of scientists were encouraged to go into the field by Hawking’s popular-level books, documentaries, or appearances on Star Trek: The Next Generation, Futurama, The Simpsons, or The Big Bang Theory. Among them could be a future Nobel Prize winner in Physics, the one major prize that eluded Hawking. But as he clearly demonstrated, one does not need a Nobel Prize to have an impact on the world of science, just as one does not have to be able-bodied. Despite losing his ability to walk, talk, or take care of his basic individual needs by the time he was in his early 40s, Stephen Hawking made an indelible impact on our world. It has been argued that it is precisely because of these challenges that he became so famous, as the public image of a brilliant mind seemingly trapped within an immobile body became burned into our collective consciousness. Hawking himself, however, preferred to consider his mind to be free, unfettered as it explored the cosmos using only his imagination and the power of mathematics.

We should never forget, however, that Hawking’s long life very publicly and honestly educated us all on what a cruel, cruel disease ALS is, and the very real challenges facing the differently-abled in our society (especially those without the resources available to the famed physicist). Having lost a cousin to this heartless ailment, it would be easy for me to ask why Hawking was able to survive for so long and not Dennis. Instead, I take comfort in Hawking’s five-decade-long delight in enthusiastically thumbing his nose at the grim reaper.

Although his computerized voice is forever silenced, Stephen Hawking finally knows the answer to life, the universe, and the theory of everything. His life path was not an easy one, but he accepted it with humor, courage, curiosity, and an unabashed gusto for life that we would all do well to emulate.

Once in a “No Moon”?

url

January 2018 featured two full moons (on the 1st and 31st), both “super moons,” with the second also featuring a total lunar eclipse visible from the Western US. But given the fact that the time between two consecutive full moons is 29.5 days, and February only has 28 days in a non leap year, January’s full moon boon has led to February’s bust. That’s right, February 2018 has no full moons, and, to add insult to injury, March 2018 has two full moons. That’s two blue moons in a single year, something that is not rare, but certainly an interesting consequence of our calendar system. The last time February was ripped off in this way was 1999, and the next time it will happen will be 2037. This 19 year “Metonic” cycle is due to a cyclical pattern in solar and lunar calendars. February is definitely not a good month for werewolves – unless you’re trying to avoid howling.

Seeing Stars in a Different Light

Father Angelo Secchi (June 29, 1818 – February 26, 1878)

When discussing the relationship between astronomy and religion one often recounts the tension between Galileo and the Catholic Church in the 17th century. But the Vatican has hosted its own astronomical observatories for many years, and some of the discoveries made in these facilities have changed astronomy forever. A case in point is the work of Father Angelo Secchi, who died on this day in 1878. Father Secchi was a pioneer in the study of the spectra of stars. By passing starlight through a prism, astronomers can divide the white light into its constituent colors, allowing us to determine what stars are made of. Father Secchi did his work before spectra could be photographed. Hence his spectra were captured by the eye and hand, put onto paper through watercolors or colored pencils. His scientific papers were not only brilliant, but beautiful to look at.arcetri_scheda_5a

Father Secchi developed one of the very first spectral classification systems, as illustrated above. While large photographic surveys led to new classification systems, his work was an important first step in our understanding of stars, and for this reason we remember and honor Father Secchi on the anniversary of his death.

Astronomy Minors Angie Colella (L) and Sara Poppa (R) volunteering at a local rock and mineral show.

Students interested in astronomy have the option of Minoring in either Astronomy or Astrobiology at CCSU. While most students pair this with a major in Earth Sciences or Physics, there are other options available. On our sister blog, CCSUGeologyRocks, we are currently highlighting some of our awesome students. Please take the time to get to know some of the stellar students minoring in astronomy and astrobiology!
