The environmental impact of oysters, in one photo
The water in both tanks came from the same source. The one on the right has bivalves. Not only do oysters naturally filter the waters in which they live, they can even protect humans from destructive hurricanes. For more, read about New York’s efforts to bring back oyster populations in the once-toxic Hudson River.
Delicious AND helpful. Who knew?

Can you tell which plot above is randomly generated?

Being able to determine if something is “truly” random is not just an investigation carried out by forensic accountants, sociologists, and law enforcement. Rather it is an interesting and complicated mathematical problem. Consider the two plots above. You may look at the on the left and see the clumps, the spacing, and think “That can’t be the random plot.” And yet it is. The plot on the left has been randomly generated, while the plot on the right is a scatter plot of glowworm positions on a ceiling.

So here, the clumps actually help indicate randomness. Try thinking of it in another way: imagine you have two students who were asked to flip a coin 100 times for homework. The first student was diligent and flipped accordingly:

THHHTHTTTTHTTHTTTHHTHTTHT
HHHTHTHHTHTTHHTTTTHTTTHTH
TTHHTTTTTTTTHTHHHHHTHTHTH
THTHTHHHHHTHHTTTTTHTTHHTH

The second student was lazy and decided to make up his flips:

HTTHTTHTHHTTHTHTHTTHHTHTT
HTTHHHTTHTTHTHTHTHHTTHTTH
THTHTHTHHHTTHTHTHTHHTHTTT
HTHHTHTHTHTHHTTHTHTHTTHHT

Now while it might seem strange that the first student has long runs, it fits closer to what one would expect if the flip is random. On the other hand, in the second student’s data, there is less than a 0.1% chance that they wouldn’t get a single run longer than four in a row!

The images and coin flip data was found at this article. It takes a closer look at some of these topics and provides some pretty neat historical background.

For people who don’t have time to bathe or access to fresh water, a South African college student has a solution: a shower gel users simply rub onto their skin. One small packet replaces one bath, and users never need any water. Ludwick Marishane’s inspiration was a lazy friend, but his invention will be a boon to people who live in areas where clean water is in short supply. 
The gel, called Drybath, kills germs, moisturizes the skin and exudes a pleasant, light smell, unlike hand sanitizers, according to Marishane’s website, Headboy Industries.  [Continue reading.]

this makes me very uncomfortable

This would mess me up because I would reach for my face and see the wrong hand go up and just completely freak out
