Butterfly Wings Xeroxed

first_imgIf you can’t build it, copy it.  Scientists have had a hard time reconstructing the photonic crystals that make butterfly wings shimmer with light (01/29/2003), so they made, in effect, a carbon copy.  PhysOrg described how scientists at Penn State made impressions of the regularly-spaced geometric shapes from a butterfly wing and transferred it to glass, leaving a “positive mold that looks the same as the butterfly wing from the top.”  Maybe instead of biomimetics this could be dubbed biomimeographics.    What do they want to do with their replicated photonic crystal?  They have their eyes on semiconductor devices, infrared sensors, solar energy concentrators and other things no one has thought of yet.  What they know is that the “structural color” reflected by these crystals will be pure and intense.  That’s bound to be useful or just pretty.True science seeks to understand a natural phenomenon with observation, equations and experiments, with an eye toward improving human life.  It’s not necessary to tell a story about how the butterfly invented a technology that human intelligence can photocopy but not yet engineer.(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

The Dana Dolly: A Quintessential Cinematic Tool for Filmmakers

first_imgFeaturesThere is a laundry list of features. First, the system is capable of supporting cameras and tripod head mounts from 75mm, 100mm, 150mm, and even Mitchell Mounts. This system can support anything from an A7S II up to a fully rigged Alexa package. Simply put, this versatility is what makes it so usable.Because the wheels can swivel, you can rig it with a curved track — something you can’t do with a slider. As a result, this provides unique camera movements to help make your shots more dynamic. Overall, the Dana Dolly is a versatile piece of filmmaking equipment that many filmmakers choose to use when creating their content. If you’re looking for smooth, cinematic camera movements, this system is just what you’re looking for. Cover image via Dana Dolly.Looking for more on working with a dolly?

It’s reliable, affordable, and it yields high-quality, cinematic results. For its price point, this is a rarity. Since its introduction to the filmmaking market, this dolly has made its way onto the rental trucks of Hollywood features, and even into the trunks of Honda Civics — for filmmakers and content creators of all stripes.Image via Dana Dolly.What Is a Dana Dolly?The Dana Dolly is a heavy-duty camera slider and dolly system. It helps you capture smooth, cinematic camera movement. In a very simplified sense, the system’s construction and appearance hearkens back to a skateboard on a rail system — although there are some key differences. The Dana Dolly conveniently and efficiently achieves its cinematic movements by sliding on its custom wheels using a piece of metal piping known as a speed rail. The combination of these materials helps to achieve cinematic dolly movements and shots.Dana Dolly vs. SliderA Dana Dolly is much larger than a slider. If you’re in extremely tight quarters, a slider may make more sense. However, there are many advantages compared to a traditional slider. For example, this system can hold and secure much larger, heavier camera systems. The amount of support and strong construction also provides much smoother camera movements.A Dana Dolly can also run much longer track lengths. This allows you to get much longer dolly pushes. Essentially, you can dolly a shot as far as you have the track to support it.Now, an advantage that a slider has over a Dana Dolly is that it’s much more compact and far more travel-friendly. While you can make a Dana Dolly somewhat compact and travel friendly, you’ll always find that a slider is much more mobile.last_img read more

Ilyasova spearheaded a late rally in which Atlanta erased a 12-point deficit and tied it at 84 on Kent Bazemore’s 3-pointer with 3:30 left. Antetokounmpo answered with a mid-range jumper and layup to open an 8-0 run following a timeout. Schroder and Bazemore then whiffed on open layups following a steal with less than a minute left that could have helped the Hawks mount one last comeback.“It’s guys making plays, that’s what it came down to. Making the extra effort, trying to get to the right spot defensively to close out,” Prunty said.Better defense has lifted the Bucks since Prunty replaced the fired Jason Kidd on Jan. 22.

They’ll pull out a few positives from challenging a playoff contender on the road.“We’ve kind of stopped looking at records and the standings,” Bazemore said. “Our coach and our front office likes the nucleus we have here, we’re all growing … it’s getting the pieces in place, getting the experience and we continue to push.”TIP-INSADVERTISEMENT John Lloyd Cruz a dashing guest at Vhong Navarro’s wedding Globe Business launches leading cloud-enabled and hardware-agnostic conferencing platform in PH 2 ‘newbie’ drug pushers fall in Lucena sting Read Next AFP official booed out of forum Milwaukee Bucks forward Khris Middleton, left, is fouled by Atlanta Hawks guard Kent Bazemore, right, during the first half of an NBA basketball game Tuesday, Feb. 13, 2018, in Milwaukee.
