That old camera in the back of the closet … and other science stories

Old cameras fascinate me. I still have my father’s old Argus C3, my mother’s Kodak Brownie Starmeter, and a couple of vintage Instamatics, among others. Somehow I acquired an Argus 75 box camera and a busted Falcon Miniature — there’s a hole in the latter’s body where the shutter button used to be, so that the interior will never be lightproof again. I’m not sure whether those two were purchased by Dad or another family member, but I ended up with them.

My interest in old cameras is certainly not limited to my personal stash. I totally geeked out when I was doing that OPN article on “Photography in the American Civil War” and got to spend an entire Saturday afternoon watching a guy making tintypes in Gettysburg, Pa. And I’ve written about the use of cameras and other optical equipment during the Apollo program in the late 1960s and early 1970s; it’s in the hands of the OPN editors now and will probably appear later this year.

So, imagine my delight at recent news reports that the widow of the first man to walk on the moon, Neil Armstrong, found a bag of his Apollo 11 memorabilia in the back of her closet — and, even better, lent them to the Smithsonian’s National Air & Space Museum. Best of all, the 16-mm Data Acquisition Camera that was supposed to have been left behind on the lunar surface came back to Earth!

I will have much more about this in my future OPN article, but basically, Apollo 11’s Eagle lander carried both video and film cameras. The video camera, mounted on the lander’s base, was pretty low-definition even by the standards of 1969 (that was the year the charge-coupled device was invented, but it certainly was nowhere near ready for prime-time broadcasting). The 16-mm motion picture camera was mounted so that it could look out the window of Eagle‘s ascent stage. It took much sharper pictures than the TV camera, but of course, no one could see those images until Columbia brought the film canisters (and astronauts) back home and technicians developed the film.

Many video clips of the Apollo 11 landing, such as this one, combine the film from the Data Acquisition Camera from the audio recorded by the Manned Spacecraft Center in Houston. What many people, especially those born after 1969, don’t realize is that the worldwide audience back on Earth could not see the film images in real time.

What the viewing public actually saw looked more like the CBS footage that you can find here and here: the live NASA audio combined with the voices of the television anchors, canned prepared animations, and the occasional “live shot” of people watching the coverage on giant screens. Because Armstrong had to steer around a boulder-strewn field at the last minute, there was a scary lag between the matter-of-fact animation’s depiction of the touchdown and the actual moment of contact with the lunar soil.

I can hardly wait until Armstrong’s stash goes on display at the Smithsonian. It will be awesome to see the actual camera that took some of the most exciting motion-picture footage of my lifetime, even if it wasn’t broadcast in real time.

(NASA’s own inventory of the objects appears here.)

Before I sign off, I’d like to mention a few other science-related stories that I’ve recently found interesting. I think I’ve mentioned most of them on Facebook, either on my personal or my professional page.

  • First, a Pittsburgh startup company has gotten FDA approval for a new kind of internal tissue adhesive. I know someone whose husband could have really used this stuff after the abdominal surgeries he’s had over the past couple of years. The scientist who developed the adhesive is married to one of my high school classmates.
  • A handheld Raman spectroscopy probe could help neurosurgeons find sneaky, aggressive cancer cells within brain tissue. This too is rather near and dear to me at the moment, because a close friend of a close friend is in hospice care for glioblastoma, which is pretty much the worst kind of brain cancer you can get. She just turned 46 years old, which is way too young to die.
  • Finally, in March and September, you’ll have a couple of opportunities to help measure the brightness of the night sky where you live. You should have no trouble remembering the March date on which this citizen-science effort begins, because it falls on Super Π Day.

Jyväskylä: The “City of Light in Finland” balances lux and luxury

Here’s a nice post from the International Year of Light’s official blog. Jyväskylä (please don’t ask me how to pronounce that!) is about 300 km north of Helsinki, as far as I can tell from online maps — not far enough north to be truly Arctic, but still up there in the “long winter nights” department. I like this city’s approach to good urban lighting design, with due consideration to mitigating light pollution.

Jyväskylä located in Central Finland is a lively city with a growing population. Finland’s seventh largest city is home to almost 136,000 people. Jyväskylä, well known for its green surroundings and Alvar Aalto architecture, is also Finland’s City of Light.

Welcome to the International Year of Light!

Yes, I know I haven’t updated this blog in a long, long time.

Back in November, I started to write a roundup of all the great things that had happened in optics and photonics during the previous month. I actually wrote this much:

What an exciting month for the field of photonics! Granted, I was often busy and didn’t have time to write cogent posts about the breaking news (I’ll come back to that later), but I was following everything avidly.

Of course, the major expected occurrence was the awarding of the Nobel Prize in Physics. Every year I hope for one of two things: a female physics laureate (about which I’ve posted in the past) or a Nobel awarded for some optics-related discovery. Well, this year we got the latter: three scientists who invented blue LEDs, which in turn led to the development of white LEDs (the white diodes are blue diodes covered by a yellow phosphor). The very next day, the Nobel Prize in Chemistry went to three men “for the development of super-resolved fluorescence microscopy” — optical imaging techniques that allow us to see the tiniest molecular details inside cells.

Some, but not all, of the laureates are members of OSA – The Optical Society, which fired off press releases about these prizes. OSA signed up one of the chemistry laureates to give some remarks…

I’m certain that I was about to write “… to give some remarks at Frontiers in Optics, the Society’s annual meeting,” or something like that. But then I got busy with my freelance writing and my job applications and all sorts of other things, and the days ticked by, and then my friend Yvonne Carts-Powell wrote an awesome post on the subject in her blog, The Science of Heroes. So I just put my draft post on the virtual shelf and dived into the usual end-of-year holiday craziness.

Now it’s a new year — a time for renewal under any circumstances. But this New Year’s Day marks the beginning of the International Year of Light and Light-based Technologies. I’ve been excited about the IYL since I first heard about it, so of course I had to wrote a feature article all about it for Optics & Photonics News. I’m following the IYL team on Facebook and Twitter, and during 2015 I pledge to fill this blog with lots of exciting posts about the science of light. Happy New Year indeed!
