Bubbles...and more bubbles

This year the RPS announced a contest to be "The Science Photographer of the Year" in order to showcase some of nature's most incredible features. The winners will be anounced on October 7.
Soap Bubble Structures by Kym Cox. Bubbles want to optimise space and minimise their surface area for a given volume of air. This unique phenomenon makes them a reliable, useful tool in many areas of research. In particular, materials science and 'packing' -- how things fit together. Bubble walls drain under gravity, thin at the top, thick at the bottom and interferes with travelling lightwaves to create bands of colour. Black spots show the wall is too thin for interference colours, indicating the bubble is about to burst. This picture shows the unique structures of bubbles. According to Dominic Retch, "Bubbles want to optimize space and minimize their surface area for a given volume of air." The bubbles gravity makes the walls at the top thinner and the walls at the bottom thicker.

We're up in Northwest Spain this week, and spent the morning visiting the Camino de Santiago. It is a longstanding pilgrimage site that ends at a cathedral in the center of town. All year, millions of people walk along the path, many for over a month, and arrive to the cathedral where Saint James visited, and may have been buried. It was really interesting to see people traveling the last few kilometers of the path. We walked the last 5km of the path, but spoke with several people who had been on the trail for weeks. One couple began their trek in Normandy, France. Once we reached the city center we attended mass with all those who had finished their pilgrimage today. It was a wonderful experience to witness the faith and sacrifice of so many people who took significant time and effort to embark on, and complete their pilgrimage. Our cute little group took a picture at the beginning and the end of our walk, and somehow it turned into a new nickname, and some awesome posing. We have...

$1,000

If I got one thousand dollars mailed to me then I know exactly what I would want to buy. First, I would buy a one hundred dollar drone, then I would buy plane tickets to Chicago for one hundred dollars and once I got there I would go down to the nutella cafe and buy all of their nutella gelato for about fifty dollars and put it in a cooler that costs fifty dollars and then buy nutella with my name on it. Then I would buy an orange juice machine that I just barely checked the price and five hundred ninety eight dollars. With the last couple of dollars I would buy two packages of oreos and donate the rest to charity. I would play with the drone until my birthday and at my birthday the orange juice machine would be sitting by the counter full of oranges and there would be all of the nutella gelato on the counter ready to eat. I think it would be great if I got $1000 to spend on whatever I wanted to.
