North American Worldwind tour: Ocean Optics XXIII conference... ไปเที่ยวอเมริกาเหนือพริบตาเดียวย่างรวดเร็ว: งานสัมมนา Ocean Optics ครั้งที่ 23... 北美旋風式巡禮：第23屆海洋光學研討會

So this past month I’ve apparently been trotting around the globe and taking a tour of Canada’s Pacific Northwest and some major hubs around the US. เดือนที่ผ่านมาลีชีพจรลงเท้าวิ่งเต้นไปโลก ได้ไปถึงแคนนาดาฝั่งตะวันตกเฉียงเหนือและอเมริกา 我這個月看起來是跑遍世界、參觀加拿大的西北太平洋風景以及美國的一些重要城市。

I recently presented a poster in Victoria BC (Canada) that was accepted by The Oceanography Society. During my analysis of the spectral reflectance of seagrasses and other benthic bottom types, I was able to show that in general under certain criteria, unique characteristics were present for Amphibolis and Heterozostera seagrass species, but not for Posidonia. เมื่อเร็วๆนี้เพิ่งได้ไปเมือง Victoria BC ของประเทศแคนาดาเพื่อที่แสดง poster ของตนเองที่ได้รับการยอมรับจากสมาคมการศึกษาเกี่ยวกับมหาสมุเนื่องจากงานวิจัยของลีศึกษาเกี่ยวกับการวิเคราะห์สเปกตรัมของหญ้าทะเลและสิ่งอื่นที่อยู่บนพื้นทะเลตื้นๆลีได้พรีเซนต์ว่าโดยทั่วไปแล้วสำหรับหญ้าทะเล Amphibolis และชนิด Heterozostera จะมีลักษณะเฉพาะ แม่จะไม่มีสำรับ Posidonia 我最近在加拿大（BC省）的維多利亞介紹我被【海洋學社會】接受的 poster。我在研究海草跟其他的底棲生物類型的光譜反射率的時候，我發現在某些標準裡，Amphibolis及Heterozostera海草種類會顯示出一些特殊性質，但Posidonia卻沒有。

While visiting the quaint town of Victoria (30 min plane ride from Vancouver BC), I took a chance to step away from the weeklong conference and into the area’s nature-themed spots, including Butchard Gardens. ขณะที่ลีไปเยี่ยมเมืองเมือง Victoria อันแสนมีสเน่ห์ (นั่งเครื่องบินจาก Vancouver แค่30นาที) ในที่สุดลีก็มีโอกาสพักผ่อนจากการสัมมนามาเกือบอาทิตย์หนึ่งและนีไปที่ที่เป็นแนวธรรมชาติรวมทั้งสวน Butchard 我去維多利亞古雅的城鎮的時候（從溫哥華搭飛機30分鐘），我抓住機會遠離長達一周的研討會，然後去大自然風景區走走，包括Butchard 公園。

After the conference, I was able to visit friends in various cities – including Denver, Houston, Philadelphia/Delaware, Flushing (Queens NY), and good-old New Jersey! หลังจากสัมมนาจบไปแล้ว ลีได้มีโอกาสไปเที่ยวหลายเมืองเพื่อได้เยี่ยมเพื่อนฝูงได้แก่เมือง Denver, Houston, Philadelphia/Delaware, Flushing Queens (นิวยอร์ก) และ New Jersey ซึ่งเป็นถิ่นเก่าของลี! 研討會以後，我去各個城市拜訪朋友，包括丹佛、休斯頓、費城~德拉威、法拉盛（紐約州）、跟美好的紐澤西！

I truly didn’t realize how homesick I was for certain foods until I returned to America! These included tacos and tortillas, stouts and ales, a Philly cheese steak from Jim’s South Street, and both a NY style bagel as well as NY style pizza (**thin crust, but yet still gooey)! ลีไม่รู้เลยว่าคิดถึงอาหารที่บ้านมากแค่ไหนจนกระทั่งกลับมา USA! ทั้ง tacos กับ tortillas, เบียร์ประเภท stout กับ ประเภท ale, Philadelphia cheese steak (ฟิลลาเดลเฟียชีสสเต๊กแซนด์วิช) ที่ทีมาจากร้าน Jim’s South Street รวมทั้งเบเกิลและพิซซ่าสไตล์นิวยอร์ก (*เปลือกบาง*แต่ยังเหนียวๆ)! 回去美國以後，我真的發現我真的想家和一些家鄉的食物！包括有：玉米餅有脆脆的跟軟軟的兩種、黑啤酒跟 ale (啤酒的一種)、Jim南街的費城起士牛排、跟紐約式貝果和紐約式比薩（**薄皮但是仍會 牽絲）！

Ah….. my version of the comfort foods of USA. (Next time, I’ll have to definitely had matzah ball soup, very likely at Harold’s Diner!) นั่นแหละ… นั้นคืออาหารอเมริกันที่กินแล้วทำให้สบายใจขึ้นในของลี (คราวหน้าต้องไปซุปที่มีกินลูกชิ้น matzah ball แถว Harold’s Diner!) 啊。。。那就是我的美國舒適食物版本。（下次，很可能在Harold’s Diner我會需要matzah丸子湯!）

tl;dr version: FYFD is launching a Patreon campaign. If you enjoy FYFD and want to help support its continued growth, please become a patron today!

And the longer version: At the start of the year, I hinted that there were big things ahead for FYFD. Today’s announcement is part of that. In the past five years, FYFD has grown beyond my wildest dreams. I’m so excited, grateful, and happy to share my love for science with all of you. As FYFD’s audience has grown, so have my plans and dreams for expanding the site and what it does. I want to bring you more: videos that take you behind-the-scenes to see the scientific process firsthand, interviews that let you meet the people behind the work, and articles that explore new and exciting fluid phenomena. 

All of the research, filming, writing, and editing necessary to bring those dreams to life takes time and money. I can provide the first: from now on, I’ll be dedicating my full-time attention to FYFD. But I need your help and support to make this possible. That’s why I’m launching a campaign on Patreon. If you enjoy FYFD and want to help it continue and grow, please consider becoming a patron. Your monthly support will enable me to dedicate my full energy to FYFD and will provide funding for materials, equipment, and travel so that I can bring the science back to you.

There are also some pretty cool rewards available to patrons! All patrons will have access to a patrons-only activity feed where I post behind-the-scenes content and extras like video outtakes. It’s also a place where I’ll look for feedback on new ideas. Think of it as an extra dose of FYFD. Other rewards include getting your name added to the FYFD supporter page, getting a handwritten postcard from me, and access to a monthly webcast where I’ll chat with guest scientists and patrons. (I’m really excited about that last one!)

Whether you become a patron or not, I want to thank you for your support. None of those would be possible without you and your enthusiasm. As always, the best thing you can do to support FYFD is to tell others how much you like it. Thank you!

If you have any questions, I’ll be online all day. You can reach me via Tumblr, Twitter, or email.

Emflume1 two-minute overview

[fuckyeahfluiddynamics]

Shovel-nosed snakes and sandfish lizards both swim through granular materials like sand. Researchers at Georgia Tech used x-rays to observe their subsurface motions. Despite their different shapes, the long, slender snake and the shorter, wider lizard both move under the sand by projecting traveling waves along their bodies. The snake’s long, skinny body allows it to have more bends along its length, which increases its transport efficiency because it allows the snake to move mostly through the tunnel created by its head’s passage. In contrast, the sandfish’s motions fluidize the sand around it, enabling it to swim. Although the snake is faster, both animals have optimized their motions for fast, low-energy transit according to their body type.  (Video credit: Georgia Tech; research credit: S.

Crazy Slo-Mo Video Explains Why Rain Has That Distinctive Smell

“Have you ever smelled that distinctive, sweet aroma that lingers after it rains?

Scientists call it “petrichor,” and since the 1960s, they’ve believed it comes from oils and chemicals that are released when raindrops hit the ground.

Now, for the first time, scientists at MIT have used high-speed cameras to show how that “rain smell” gets into the air.”

See the video and learn more at the huffingtonpost.

[clientsfromhell]

I just finished a website and invited the client to the office for a final sign-off.

Client: How big is it?

Me: It’s optimized for resolutions at 1024x800.

Client: What does that mean in plain English?

Me: It’s the number of pixels displayed on the screen.

Client: I don’t do pixels....

One of the common themes in aerodynamics, especially in sports applications, is that tripping the flow to turbulence can decrease drag compared to maintaining laminar flow. This seems counterintuitive, but only because part of the story is missing. When a fluid flows around a complex shape, there are actually three options: laminar, turbulent, or separated flow. An object’s shape creates pressure forces on the surrounding fluid flow, in some cases causing an increasing, or unfavorable, pressure gradient. When this occurs, fluid, especially the slower-moving fluid near a surface, can struggle to continue flowing in the streamwise flow direction. Consider the video above, in which the flow moves from left to right. Near the surface a turbulent boundary layer is visible, where fluid motion is significantly slower and more random. Occasionally the flow even reverses direction and billows up off the surface. This is separation. Unlike laminar boundary layers, turbulent boundary layers can better resist and recover from flow separation. This is ultimately what makes them preferable when dealing with the aerodynamics of complex objects.  (Video credit: A. Hoque)

Vortex shedding frequently happens in the wakes of non-streamlined bodies as a result of flow around the obstacle. Newton’s third law states that forces come in equal and opposite pairs, meaning that the vortex shedding behind an obstacle is accompanied by a force on the obstacle. For a fixed cylinder, this is not always apparent, but for a pendulum, like the ones demonstrated in this video, this vortex-induced vibration causes significant motion. This same effect can make traffic lights and industrial chimneys sway. You’ve likely experienced it yourself as well, if while swimming you’ve ever spread your fingers underwater and spun in place. Try it sometime with your arm out and you’ll feel the vortices make your arm vibrate up and down as you spin.  (Video credit: Harvard Natural Sciences Lecture Demonstrations)
