One day left to submit “grand challenge” ideas to the White House!

My friend Damon over at Internal Reflections blog asked that I spread the word about this, as there is one day left to submit ideas.  The easiest thing for me to do is quote him directly:

Peter Emmel just notified me that the White House has put forth a request for information (RFI) for new “Grand Challenges” for the 21st Century. In essence they are soliciting ideas for a new “Moon Shot.” There are no formal formatting instructions, and anyone can participate. It is essentially a public opinion poll on how research dollars will be spent… So speak up! The main PR site is here, but more detailed information is available from the original press release.

Got a great idea of what the U.S. should be spending its research funding on?  Send it to the White House!

Michelson and the President (1869)

I’m currently working my way through the book The Master of Light: a Biography of Albert A. Michelson (1973), written by one of his daughters, Dorothy Michelson Livingston.  I typically find the beginnings of biographies to be rather slow-moving, with some sort of statement like, “There was little to indicate in his/her childhood what a great scientist he/she would become,” but this is definitely not the case for Michelson — his life story is interesting starting pretty much at birth!

I thought I’d share another anecdote from the book that I found fascinating: Michelson’s meeting, at a young age before he was famous, with the President of the United States Ulysses S. Grant!

Some happenings

I’m in the midst of a few new science blogging posts, though all of them involve me doing a lot of research and learning about things I don’t know as well as I thought I did!  In the meantime, I thought I’d share a few miscellaneous bits of personal news.

First, thanks to Personal Demon for the gifts!  In the mail yesterday, I received from him the first xkcd compilation, volume 0:

and the following xkcd t-shirt, which I will probably wear to class on Monday:

I’m not sure what I’ve done to earn such gifts, but they are appreciated!

In other news, my “official” book cover was sent to me by Cambridge University Press yesterday:

The only change I might request is the use of my full name, with middle initial, as suggested by my wife.  (I do find it amusing that the cover is essentially the image I sent them, with some text thrown on.  Apparently I’m an awesome book cover designer.)  Let me know what you think!

Speaking of books, a friend of mine, Brad Craddock, has made it to the quarter finals of the Amazon Breakthrough Novel Awards (ABNA), with his book Alice’s Misadventures Underground!  He now needs some help in the form of some nice reviews to help move the book into the next round. Quoting from his email,

In the next few days (or weeks) until April 25, Amazon is asking for reviews of the first 5,000 words or so of each entry novel. Feel free to tell the truth, but be generous and nice overall since lots of glowing reviews may help me move to the next round.
If you have a kindle  you can read the first few thousand words and rate the book. I think you can also download it, even if you don’t have a kindle. In any case, any reviews you make can help. If you’ve read the entire book, you can comment on that as well.
Here’s the link (copy and paste in the address window):
and here’s the instruction page:
and here’s the contest info:
And if you haven’t bought the book yet and want to, here’s the link:

For those familiar with Lewis Carroll’s Alice’s Adventures in Wonderland, I can recommend Brad’s entertaining take on the tale.

A book publisher could also use your help: Valancourt Books, which specializes in lovely reprints of rare and long out-of-print texts, has had some major computer problems that has put their efforts on hold until they can scrounge up enough money for a replacement.  They would really appreciate it, and you would too, if you could throw some support their way by purchasing one or more of their excellent titles.  I’ve reviewed many of them on my blog, including the excellent works of Richard Marsh, Bertram Mitford, and Marie Corelli, and have yet to find a book I didn’t like.

Did I mention that I’m now a tenured Professor?  I got the official letter on Wednesday of this week, and posted on Twitter, but I wanted to mention it on the blog as well for those non-Twitter followers.  The amusing thing is that the letter is dated April 1st; I have disturbing visions of being told six months from now that it was all a joke…

Finally, let me note that we’ve got a new houseguest!  A few weeks ago we put up a bluebird house outside of our front window, though we were worried that it was already too late in the season to get a resident.  Our fears were unfounded, however:

Fortunately, the bluebirds don’t seem to shy about having their picture taken, unlike the woodpecker who pops by now and again at our feeders…

Robert E. Howard’s El Borak

Finally, I’ve gotten to read some new Robert E. Howard!  Well, not new — Robert E. Howard committed suicide in 1936 — but new to me, anyway!

For those who are unfamiliar, Robert E. Howard (1906-1936) was a Texas author who wrote fantasy, adventure, and horror fiction for pulp magazines such as Weird Tales.  He is best known for his creation Conan the Cimmerian, though he wrote a large body of memorable work and introduced many fascinating heroes.  For instance, the title of this blog, “Skulls in the Stars”, is a title of a story of Howard’s about his character Solomon Kane, a puritan adventurer and justice-seeker.

Most of Howard’s other works have fallen into obscurity, overshadowed by the popularity of Conan, but in recent years compilations of some of them have been released.  I recently picked up a compilation of Howard’s modern desert adventures, titled El Borak:

“El Borak” is the Arabic name of American adventurer Francis Xavier Gordon, and the bulk of the tales, though not all, focus on his adventures.  The tales are stories of action and intrigue set in the deserts and mountains of the Middle East, stretching all the way to Afghanistan.

Wave interference: where does the energy go?

Last week was a relatively lousy one for me, but it was made up in part by getting a good question from a student on waves and interference after class.  It’s really nice to get a question that indicates a genuine interest in the science (as opposed to just wanting an answer to homework), and I thought I’d discuss the question and its answer as a post.

The situation in question is as follows: suppose you have a harmonic wave on a string traveling to the right such that in a snapshot of time, the string looks as follows:

This wave carries energy, and there is a net flow of energy to the right.  Now suppose we excite the string with an additional wave of the same frequency and amplitude, but completely out of phase.  The sum of the two waves then vanishes:

The two waves cancel each other out, leaving a completely unmoving string due to destructive interference.  My student asked me: what happens to the energy?  As posed, it seems that we started with two waves carrying energy, but they canceled each other out, leaving no energy!  This interpretation cannot possibly be correct, so where is the flaw in our description?

ResearchBlogging editor’s selections: Ocean conveyors, UV paleontology, science and “truth”, and scientific misconduct

  • Ocean Conveyor running AMOC. Life on our planet owes a lot to the global ocean currents, but there is concern that global warming may shut this current down.  Is there any indication this is happening yet?  Alistair at Deep Type Flow discusses the theory and the evidence.
  • UV, You See? Black Light Reveals Secrets in Fossils. GrrlScientist at Living the Scientific Life talks about an underutilized technique in paleontology — using UV light to study fossils — and the awesome scientific dividends it has already paid.
  • Climate change and philosophy of science: Does climate science aim at truth? There was a recent tiff in The Guardian, in the context of climate science, about the question of whether science aims at “truth”.  Michael at Good, Bad and Bogus does a great job of dissecting the arguments.
  • What causes scientific misconduct? We know that scientists are tempted to “cheat” at their work much too often, but why?  Janet at Adventures in Ethics and Science looks at research relating to the motivations of those who have been caught as such misconduct.

Check back next Monday for more “miscellaneous” highlights!

Michelson and Margarite

My recent posts on Ada Lovelace Day (here and here) not only drove home the point that there were even more historically important women scientists and mathematicians than I had optimistically imagined, but that the smartest male scientists of their eras appreciated their contributions and actively encouraged them.

I don’t want to obsess over the approbation of the male scientists — undeniably, the women’s contributions stand out on their own.  Now that I’ve noticed it, though, I’m spotting other remarkable and little-remembered instances, and can’t resist sharing.  These stories give me a little more faith in humanity, or at least the scientific community.

The story I want to tell in this post I came across in a biography of Albert A. Michelson (1852-1931) written by his daughter Dorothy Michelson Livingston: The Master of Light (Charles Scribner’s Sons, NY, 1973).

ResearchBlogging editor’s selections: molding stem cells, lightning, dogs at play, and a heritage of honey

  • Shaping a stem cell’s future. Most of us are familiar with the idea of stem cells (and the political controversies associated with them): cells which can be chemically manipulated into different types of functionality.  Rob Mitchum at ScienceLife describes research that has shown that this functionality can be controlled by manipulating the shape of the cell!
  • On the phenomena of lightning. How much do you know about lightning?  In the course of his radio astronomy work, Alexander at The Astronomist did some investigating and discusses some interesting facts about lightning and its generation.
  • Is My Dog Playing or Fighting With That Other Dog? Ever wonder how to tell the difference between rough dog play and a dog fight?  Jason at The Thoughtful Animal describes how dogs work it out.
  • Preserving a culture in wild honey. Finally, Alun at AlunSalt provides a thoughtful look at the disappearance of an Aboriginal tribes’ honey-gathering heritage.

As a bonus, if you were intrigued by last week’s description of macroscopic quantum-mechanical objects, Chad at Uncertain Principles provides more details on the experiment and what it actually demonstrated.

Check back next week for more “miscellaneous” suggestions!
