This entry has a common thread that everything is about different, thought-provoking visual stimuli.
The Denver Post posted this gallery by photographers from the Farm Security Administration/Office of War Information. These color slides were recovered from the 1939-1943 and show glimpses into what life was like for Americans during harsh times.
The data nerd in me really loves the blog Information is Beautiful for its use of data to create visualizations that are beautiful and interesting.
The science nerd in me loves the website The Fun Theory for the psychological experimentation it is conducting.
On May 18th, I went to a talk by Dr. Iain Couzin, hosted by the Secret Science Club at the Bell House in Brooklyn.
Couzin’s lab at Princeton investigates collective animal behavior, some of which include fish schools, bird flocks, and locust swarms.
This video shows predator and the prey swarms interacting. When the video shows it in slow motion, notice how the prey individuals can avoid the predator by keeping a cushion of space between them. Couzin talked about how they measure these movements in his lab’s research and what they hope to be able to model and measure in the future, like behavior and movement.
They are also using some really amazing tracking software to calculate the orientation and movement of fish using video taken from above the tanks. They have even started using this technology to track movements of people walking around and as part of an escape-route experiment.
I couldn’t find any videos from this section, but there was a video that Couzin showed from an experiment where they had a large group of people in a circular room. Only a few people were told which “emergency exit” was the safest exit. These people had to move towards that door and get others to follow without communication.
The most incredible thing I took away from the talk was from the discussion of locust swarms and their research on what drives the movement of these swarms.
Here is Iain Couzin giving a short talk about swarm movement:
With a slew of recent releases of gadgets that serve as ebook readers (Barnes and Noble Nook, iPad, and all the ones announced at the Consumer Electronics Show), I thought I would take some time to look back on the experience I’ve had with my Sony PRS-505 Reader and why I love it and e-ink technology. (Mine is dark blue, not like the one shown here!)
First of all, I got the Reader a little over 2 years ago in Fall of 2007. I bought it somewhat as an impulse buy, but I justified it as a long term investment. Since then, I read at least 4x more books than I would have otherwise. This is the biggest reason why I’m thankful that I decided to buy the Reader.
Here are the other main reasons why I bought it:
- I don’t have space at home for all the books that I want to read, and I don’t do well with library books (see #3)
- I don’t have the money to buy all the books I want to read (ebooks are usually cheaper, and many you might be able to find for free)
- I’m allergic to old books and dust (I get itchy all over), so I won’t be able to enjoy re-reading any of the physical books, bringing their value down over time
Here are the reasons why I love my reader now:
- It is way lighter and smaller to carry around than a book
- I like being able to immediately start reading another book once I’ve finished one
- The e-ink screen is nice on my eyes, as compared to a lit LCD screen (I get enough of that from staring at my laptop!)
I’m also happy that I chose the Sony Reader over the Amazon Kindle because any of the content that I buy from the Sony store is not locked to my device (i.e. anything bought for the Kindle only works on the Kindle, there are tons of stories if you Google “Kindle DRM”).
I don’t buy books very often, but when I do it is in a format that is more useful and open (usually ePub). The Kindle uses its own proprietary format. Also, I’m not so interested in the wireless download function of the Kindle so that does not bother me.
There was also that incident where Amazon deleted George Orwell books from all Kindles. That type of control is not something I am a fan of. Even though it was for valid reasons and they said they were changing their practices so it wouldn’t happen again, the fact that they have the ability to go into each device and perform that function irks me.
So, while I did have to shell out $280 for my Sony PRS-505, I’ve read enough books to make it worth it and I’m sure that I will be using my Reader for at least 4-5 more years.
Do you have a reader? Would you consider buying a reading device like this? I hope my comments have been helpful!

Last night, on the eve of what might be the most exciting Apple announcement this year, I wondered what a Mac slate or tablet could mean for scientists, researchers, and people in the field. Now with the iPad announced and the details of it released, here are some of my thoughts.
The increased mobility of a small device designed to be used with specialized apps and software could boost overall productivity. Functionality, combined with mobility can be incredibly useful for scientists.
For example, Wired has this list of 22 iPhone apps for science geeks that include a genetic decoder, anatomy flash cards, food information database, and a scientific calculator. These could be useful on the iPad too, since the iPad can run any apps in the store.
Increased mobile connectedness to the web can be super powerful. We are already seeing mobile technology being helpful for relief efforts in Haiti and a larger, more powerful, yet still portable, device could enhance what can be done and create new possibilities for these purposes and others.
As for ideas of specific uses of the iPad, I can imagine that a scientist could take this device into their study areas to help record data, look at maps, read reference books, and plot trails and data.
This could possibly help scientists forgo the hours and hours usually spent on data entry!!! Especially since Numbers has a function that creates a form for data entry!
I’ve also read about iPod Touches being used in classrooms to supplement math, science, language and other lessons, so the iPad might eventually make it’s way into the classroom too (but that might take a while because of cost!).
It is cool to see something like this come into being. While the iPad might not end up doing a ton for scientists, I’m still excited to see what will happen with the functionality this new tool!
When you train your dog to bring you the morning paper, that is a neat trick. When you train your computer to bring you news you want to read, that is an RSS feed.

I never fully appreciated RSS feeds for what they can do until I started reading the book We the Media by Dan Gillmor. The underlying idea is that you don’t need to search the Internet for the things that interest you but that they come to you through your RSS subscriptions and preferences.
This is useful for you when you want to be kept up to date on certain topics. Anytime there is an article, your RSS feed is updated to show it. I currently use Google Reader to keep track of blogs, job postings, and news.
Gillmor discusses another way to use RSS, which is to follow what is being said about yourself. This is a good way for popular bloggers and organizations to know what is going on in their realm and connects with their readers on a different level.
Honestly, I haven’t used RSS feeds enough in the past but I’m starting to really appreciate what they do. It could particularly be very helpful for my current job search!




Connecting the path to energy savings with “No on Prop 23″ funding

Today I started reading news in Google Reader, and came across 2 topics that I wish could just find a way to meet up. They have to do with getting widespread behavior and mentality change to happen and funding for political campaigns/issues. That may not sound like they can be connected, but just read on!
The first article is titled “Misperceived Paths to Energy Savings” from the Dot Earth blog on the New York Times. It that talks about a study published in the Proceedings of the National Academy of Sciences (PNAS). The researchers surveyed regular people and found that they generally do not have the right idea about what the most effective ways to save energy are, when compared to what is recommended by experts. The best ways to increase energy savings, according to this study, are efficiency improvements, rather than usage curtailment. (Though both may be necessary, in my opinion.)
I think what they are trying to stress here is that people have the idea in their heads that if they just turn the lights off when not in use or drive a little less, that that will be enough to make a major difference, that they can “do their part” in these small ways. While these behavioral changes are good and great, there really isn’t much of a change in mentality or understanding of the deeper issues. There is still a self-centered approach to those activities, whereas more significant action would take more significant effort (i.e. buying more efficient light bulbs, appliances, water heaters, cars, etc.; insulating your home).
The NY Times journalist suggests that this study is a sign that the US needs to invest more in energy literacy in order to make a dent in the wasted energy and avoidable carbon emissions related to energy use.
The next article I would like to bring into this discussion is about Proposition 23 in California. You can find the second article here at Grist. Prop 23 opposes the climate change legislation in California, and is supported by big oil companies from other states such as Texas. The campaign against Prop 23 also has big backers, such as environmental groups, tech companies in Silicon Valley, and other companies. All in all, there are several millions of dollars going into the campaigns on both sides.
I won’t get started on how unrestricted lobbying could possibly be one of the big reasons why our local and federal governments continue to fail on important fronts, because that would be too much of a tangent. But I couldn’t help thinking, what if they took those millions of dollars going into campaigning and actually put it into informative programs on the ground to address issues like energy efficiency? Maybe it wouldn’t even take that much seed money to get something going, because apparently home energy efficiency is a booming business.
Now, I’m not actually suggesting to take the money out of the No on Prop 23 campaign, but what if every group that invested in the campaign matched with an investment into an energy literacy program? Rather than only putting money into TV and radio ad campaigns that may not increase the general public’s understanding of climate change legislation but confuse people more?
I do not wish to resign to the idea that people are mindless and believe whichever campaign had the most funding and was therefore more prominent. Maybe I don’t understand enough about what is going on. I admit that I sometimes do not understand why people are such adamant deniers of climate change.
In any case, the point is that there really isn’t enough effort or funding going into informing the masses and this could potentially be an innovative way to raise funds and awareness. I would really like to see a lot of things become part of general knowledge, like climate change and evolution, which really deserved to be a part of general knowledge decades ago.
