Using lasers to build molecules instead of tearing them apart

In general, the world of chemistry is a closed book. Reactions happen, and my understanding is limited to counting electrons and seeing if they add up. Despite this ignorance, there is a particular field of chemistry that I really love: photochemistry, or chemistry driven by light. Nothing gives me more pleasure than setting stuff on fire with a laser—I mean carefully studying light-controlled reactions.

Seriously though, there is this whole field out there where chemists and physicists study and control reactions using light. Or, more accurately, they study how to control the breakup of molecules using light fields. These experiments make use of something called coherent control, where we use light to steer electrons. As a result, the light controls the chemistry. But creating molecules using the same idea has proven to be hard—really hard. That makes a recent publication on the creation of molecules using coherent control reasonably important.

Coherent destruction

One of the easier—and I use that word in the sense of "not impossible"—demonstrations of coherent control involves tearing molecules apart. The reason this is easy is because as long as your laser is powerful enough, you can always tear molecules apart. That means you can always start with a light pulse that does the job, then by tweaking the pulse shape (more on that below), you can increase the efficiency with which you break molecules. Or, you can aim to break particular bonds.

BCBG Fall 2015

Designers really went back to the 1970s for autumn. The BCBG fall 2015 collection by Max and Lubov Azria was all about groovy knits and folksy embroidery. The color palette had a range of earthy neutral colors like sand and tan. Brighter colors included red, orange, brown, and navy. 

The design team worked the colors into a color blocked patterns, something I have seen from them in the last few seasons. They also worked in some faux fur for when the weather gets cold. Being a West Coast based fashion brand, many of their team probably doesn't see the winter, so naturally, lots of layering was involved to accommodate all climates. There was a lot of thread embroidery that emulated the techniques and patterns the design team saw in their foreign travels. This added to the global nomad hippie vibe of the overall runway. 

I saw less handbags in this show than previous ones. BCBG looks like they finally graduated from the flat envelope clutch to the bigger, chunkier envelope clutch. In footwear, it was all about the tan leather boot. A lot of tan leather boots.

No doubt, NY Fashion Week was all about the 1970s. Some designers went with luxurious disco glam. BCBG Fall 2015 went with bohemian chic. There's a look for everyone in that decade.

Blogger Love: Summertime Style



As I read through the submissions for this week, I couldn’t get the music of George Gershwin’s Summertime from Porgy and Bess out of my head.  With each post of Summer Fashion, the lyrics would start over, “Summertime, And the livin’ is easy…”  So, IFB Bloggers, I suggest background music this week as you click through these inspiring links. {My favorite Summertime rendition is performed by Billie Holiday}    -Kim Toomey

A 100-Seat Church Constructed From Living Trees in New Zealand by Barry Cox

treenchuch_09

Located in the same island country that the Lord of the Rings trilogy was filmed is a structure that, like the hill-secured homes of the hobbits, also seems to hide within its natural environment. The Tree Church is formed almost entirely from living trees with thick leaves covering its shady interior. The New Zealand-based church can seat a hundred people and was first planted by Barry Cox on his property near Cambridge beginning in 2011.

The original inspiration behind the structure was a means for Cox to “retreat from society.” However, after others caught word of his living church as it grew into completion over the last 4 years, he decided to open it and the surrounding gardens for public and private events. The Tree Church is now set within three acres of extensive shaded gardens, including a labyrinth walk based on the ancient city of Jericho from 460 BC.

An iron frame is at the core of the church, as Cox wanted the walls and roof of the natural building to be distinctly different, “just like masonry churches,” he said. Cut-leaf alder was chosen for the roof as it is flexible enough to be trained over the frame which will be removed when the branches become strong enough to support the church themselves. (via Faith is Torment, Inhabitat)
