Every city that has public transportation struggles with fare jumpers — people who sneak onto the subway or the bus without buying a ticket. In Sweden, fare-dodging is a brazen movement in which the group’s members don’t try to hide what they’re doing.

On a weekday morning, students in backpacks and winter coats stream out of the university subway station in Stockholm. Some people have set up a booth here with a hot pink logo of a man jumping a turnstile, and a sign that says Planka.nu. In Swedish, that roughly means “dodge the fare now.”

Group Urges Swedes To Evade Subway Fares, And Even Insures Against Fines

Time for a snapshot of the science-y words in “State of the Union" addresses since 1900. I took word frequency data (words per 10,000) from onetwothree.net and grouped the words by topic. For example “doctors,” “vaccines,” and “medicine” were all included in the “HEALTH” total. I added global oil prices (adjusted for inflation, source: BP Statistical Review) as a reference.

Things I noticed:

Presidents tend to talk more about alternative fuels and climate change near the end of their presidencies. Hmmm …

The 1973 Oil Crisis really got ‘em talking.

There’s a major shift from worrying about agriculture to worrying about health.

Look how excited Nixon was about natural resources!

Interesting how infrequently Obama uses health words compared to Clinton and Bush 2.

A fascinating look at the use of science words in State of the Union addresses. Interesting to see what trends exist in terms of popularity of topics. -Tajha

I’ll be in a restaurant and I’ll see a couple and they’re both on their phones. I wanna go over to the guy and say “look man, she is beautiful, just put your phone away and look at her, talk to her” y’know

Schlieren photography offers a glimpse into flows that are usually invisible to the human eye. With a relatively simple set-up—a light source, collimating mirror(s), and a razor blade—it becomes possible to see differences in density. The technique lets one visualize temperature-driven flows like the buoyant convection from a flame or other heat source, and it can also be used to visualize shock waves and sound. The video above has several neat schlieren demos, including some non-air examples using hydrogen (lighter than air) and sulfur hexafluoride (denser than air), both of which are transparent to the naked eye.
