Introducing Science Monday — “Where’s My Jetpack?”

jetpack.jpg

For the next few Mondays I’m going to try to post a science related. Today I’ve expurgated Salon’s review of Daniel H. Wilson’s “Where’s My Jetpack”. You can also read the complete review but if you are not a Salon subscriber you may have to watch an advert.

Staring out of my window in Manhattan’s East Village the other day, it struck me suddenly that the street scene below did not differ in any significant way from how it would have looked in 1967. Maybe even 1947. Oh, the design of automobiles has changed a bit, but combustion-engine-propelled ground-level vehicles are still how we get around, as opposed to flying cars or teleportation. Pedestrians trudge along sidewalks rather than swooshing along high-speed moving travelator. 21st century New York looks distressingly nonfuturistic. For a former science science fiction fanatic like me, this is brutally disappointing. Continue reading

Rapatronic Wednesday

From Damn Interesting (one of my favorite ways of wasting time on the internet).

I saw this for the first time two months ago and the images have set up shop in the same part of my brain that houses the 500 kV video I posted last month. I find these images sublime and hypnotic — like catching a glimpse of the end and beginning of the universe.

During the early days of atomic bomb experiments in the 1940s, nuclear weapons scientists had some difficulty studying the growth of nuclear fireballs in test detonations. These fireballs expanded so rapidly that even the best cameras of that time were unable to capture anything more than a blurry, over-exposed frame for the first several seconds of the explosion.

Before long a professor of electrical engineering from MIT named Harold Eugene “Doc” Edgerton invented the rapatronic camera, a device capable of capturing images from the fleeting instant directly following a nuclear explosion. These single-use cameras were able to snap a photo one ten-millionth of a second after detonation from about seven miles away, with an exposure time of as little as ten nanoseconds. At that instant, a typical fireball had already reached about 100 feet in diameter, with temperatures three times hotter than the surface of the sun.

Mental Health Monday

OK, so here is my first post in a while- a two-parter.

I have recently been thinking in systems theories, particularly as they partain to groups like ours. How closely does life imitate art, I ponder. In a system, each part of that system serves a function and hopefully the whole of the system is able to obtain homeostasis, that is to say, a conistancy in functioning. Our group, I would contend has been consistent over time to a degree, and has righted itself here and there over the years. So, when TV shows, movies, and theater is written, one wonders how much of what they are trying to capture could be represented in our little group. What I would suggest is that this may occur more than we think.

An interesting little experiment we might do here is to have each person consider the cast of a few shows and movies and submit them to me. Feel free to add shows, or movies we might all have some degree of familiarity with. What I would be interested in is:

1) how we see ourselves; what roles we envision ourselves in
2) how others see us
3) how well those match.

This may give us some clues as to some of the roles we fulfill with in the structure of our group. Some obvious shows: Star Trek (original and next generation), Lost, U2 (not a written cast, but a group whose members function as a system), Lord of the Rings, Harry Potter, M*A*S*H*, the Office. Maybe we want to choose 2 or three to get started. Suggestions? Send them to me this week, and I will tally and report on them next Monday. I am also open to any suggestions on how to better this experiment.

The next line of business is not related with any intention to the first. I would submit that we all look at taking 5 minutes and filling out a Myers-Briggs test. Human Metrics has one that has a number of questions which should provide some validity to the project. This is strictly for fun only, and does not have any problematic mental health implications. This is a test used primarily by psychologists and is a fun way to compare what the test says about personality traits so we might compare how that measures up with observation of self and others. Really not much more than a conversation peice which may give everyone a little insight about themselves and how they function and work, what strengths they might have. I would be interested to get feedback on how whether or not everyone feels the tool is accurate or inaccurate and why. There are several of these on line, and they are not the actual test, but my experience has been that they are fairly predictive in capturing the flavor of the test. This one is a little longer than the others which should help create more validity. There are no right answers just how you feel. being honest with yourself and not playing to the bias that you feel the questionare is seeking is most likely to result in the most accurate tabulations. I took it and will take it again after I post to see if my result is consistent again. I was an INTJ.

Here is one more if you get bored or want to compare your result to another test.

I am looking forward to hearing what you guys find out. By the way, Happy New Year to all.

Engineering Wednesday

Thanks for the Rolomite post Toby! In my opinion the blog over-represents nostalgia and doppelgangers to the exclusion of engineering and science.

Here is my offering: The Fletcher Capstan Table.
