![]() When a beam of light travels from one medium to another-from air to glass, say-its speed changes, causing the beam to bend, or “refract.” The difference in index of refraction between the two materials defines the angle of that bending. Smith of Duke University, the late Sheldon Schultz of the University of California, San Diego, and their colleagues created an engineered material unlike any seen before-a material with a negative index of refraction. The modern era of metamaterials can be traced back to 2000, when physicists David R. Bose's twisted jute showed that it was possible to engineer an artificial material to control light in unprecedented ways. ![]() By manually twisting jute fibers and arranging them in regular arrays, he demonstrated that linearly polarized electromagnetic waves-light whose electric and magnetic fields oscillate along straight lines-rotate their polarization as they propagate through and interact with the jute structures. ![]() In the late 19th century, a few years after James Clerk Maxwell's discovery of the equations of electromagnetism, Jagadish Chandra Bose built the first examples of what we could call a metamaterial. Although humans cannot distinguish one polarization from another with our eyes, several animal species have polarization sensitivity, allowing them to see more, better orient themselves in their surroundings and signal to other creatures. A third important property of light is its polarization, which describes the trajectory that light's electromagnetic fields trace in space over time. Human eyes are excellent at detecting two fundamental properties of light: its intensity (brightness) and its wavelength-that is, its color. In the 17th century Isaac Newton and Robert Hooke recognized that the hue and iridescence of some animals are created by nanoscale patterns on the surface of their body parts-another example of how nanostructured materials can create surprising optical effects. The tiny metal nanoparticles dispersed in the glass absorb specific wavelengths and let others through, creating bright colors in masterpieces that we still admire today. An early success in this quest was the invention of stained glass: ancient Romans and Egyptians learned how to melt metallic salts into glass to tint it. Bending and Twisting Lightįor centuries scientists have strived to control the properties of light and sound as they interact with our sensory systems. With modern nanofabrication tools and a better understanding of how light and matter interact, we can now structure metasurfaces to produce any pattern, color and optical feature we can think of. Other metamaterials allow light to travel one way but not the opposite-a valuable tool for communication and detection of objects-and to break symmetries of geometry and time. Although these inventions have limitations-they aren't quite the Harry Potter–style invisibility cloaks that many people imagine-they nonetheless interact with light in a way that seems like magic.Ĭloaks are just one example of metamaterial technology. Several research teams around the world, including mine, have designed and produced metamaterial coatings that can redirect light waves that hit them, effectively preventing light from bouncing off the object and reaching our eyes and even from leaving shadows. The marquee example of this new style of materials is the “invisibility cloak”-a metamaterial coating that can hide an object in plain sight. The Greek prefix meta means “beyond.” These engineered materials let us move beyond the traditional ways in which waves and matter interact, creating technologies where light and sound appear to disobey conventional rules. And recently there has been a revolution in our ability to control these waves using materials, engineered at the nanoscale, known as metamaterials. Remarkably, all these different waves are governed largely by the same fundamental physical principles. Electromagnetic waves bring radio, television and endless streaming content to our devices. Light waves stimulate the retinas of our eyes. tiny vibrational waves transport sound to our ears.

Why is the FedEx driver asking to scan my ID at delivery?Įffective 06/28/22, FedEx will introduce scanning technology that electronically captures the recipient’s first initial, last name, and automatically verifies age requirements are met for deliveries requiring an adult signature. If this occurs, FedEx may no longer automatically reattempt delivery and the package will be taken to a nearby FedEx location to be held for you to pick up. In some situations, a label will be applied to the back of the doortag, because the driver was unable to leave the package due to signature requirements or package safety. This is only eligible for indirect signatures. This will authorize next-business-day delivery. ![]() If you are given the option to fill out a form and leave your signature on the door tag, then you can follow the prompts on the form and sign. Sign the back of the form on your door tag (if eligible).Text the word follow and your door tag number (located at the bottom of the doortag) to 48773 (ex: follow DT999999999999).Track online by entering in the tracking number located at the bottom of the doortag.You will get specific information about your missed shipment and your available delivery options. Download the FedEx®Mobile app and scan the barcode on your door tag.If you received a doortag, you will need to follow one of the options below: If you’re away when we try to deliver your package that requires a signature, we’ll leave a door tag that provides the key details you need about your package pickup or delivery. You must sign in person for adult or direct signature requirements. If your shipment requires an indirect signature, then you can sign electronically through the FedEx Delivery Manager app or on, but you cannot sign electronically for packages requiring an adult or direct signature. If you already missed a delivery and received a door tag, make sure to follow the instructions on the door tag to ensure your delivery is made on the next attempt. To avoid missed deliveries, sign up for FedEx Delivery Manager to request to hold your package at a FedEx location for you to pick up. If you want FedEx to reattempt a delivery, call 1.800.463.3339. The door tag and a government-issued photo ID are needed for pickup. The label on the door tag includes the pickup location address, business hours and time the package will be available. In those situations, FedEx may no longer automatically reattempt delivery and the package will be taken to a nearby FedEx location to be held for you to pick up. If a label has been applied to the back of the tag, the driver was unable to leave the package due to signature requirements or felt the package was not safe to deliver. If a signature is required, the driver will typically try to deliver the package up to three times. If no signature is required, the shipment will be left at the recipient's door. If a shipment requires, either an indirect, direct or adult signature, and a delivery attempt is made, but no one is there to sign for the package, the driver will leave a door tag at the recipient’s door. ![]() Through the wars and invasions that they inspire, the objectives are considerably better at spinning a yarn than the narrative events, too. ![]() It’s still a sandbox, but it’s not quite as messy. They do, however, give Empire Divided considerably more direction than plain Rome 2. Like the rest of the heroic factions, the Gothi get some unique objectives, though they’re lamentably just a string of targets - conquer this province, occupy or sack that city - with some flavour text and very few deviations. It's a far cry from the scripted battles, hunts for artefacts and quest chains that I've gotten used to during my battles across The Old World over the last couple of Total War games. Did he get his wolf pelt cloak by hunting the beast on his lonesome? Was boozing his one true love? Each choice gives leaders new bonuses, though it's not remotely clear what they are when you select them. Each of these vignettes allows you to pick how he tells the stories. His story is simply told via a series of narrative windows where he spends his time regaling his warriors with tales of his old adventures. They're led by Cannabaudes, a veteran of countless battles and campaigns. ![]() In my first attempt to become Rome’s new boss, I played as the Gothi, the only heroic barbarian faction. And there are no better Total War games from which to take inspiration for faction design. A bit of added flavour, a dash of roleplaying, faction-specific objectives - it all sounds a lot like Warhammer, at least on paper. Half of Empire Divided’s factions are ‘heroic’, getting their own unique victory conditions, bespoke event chains and special leaders who can’t die in battle. The scope is considerably larger than previous expansions, with ten factions - including the three Roman states - and a whole host of mechanics that aren’t strictly new for the series, though they are for Rome. It’s pretty fertile ground for a Total War game. ![]() It was the most popular Total War game before Creative Assembly started dabbling in fantasy, however, so the audience is quite a bit larger than, say, Attila’s, which I suspect explains why it’s seeing this resurrection.Įmpire Divided’s campaign takes place during the Crisis of the Third Century, which saw the Roman Empire almost destroyed by wars, plague and its separation into competing Roman states. It’s four years old, not even the latest historical entry, and in terms of both the presentation and the real-time battles, it’s a step backwards from Warhammer 2. Rome 2 is probably not the best showcase of the future of Total War’s historical games. So where does that leave Total War: Rome 2 - Empire Divided? Total War’s historical games will undoubtedly continue to appeal to those craving a more grounded strategy romp, but so many of the series’ most significant improvements are inextricably linked to a fantasy premise. How can a historical Total War compete with dinosaurs besieging a fortress filled with wraiths and shambling corpses? Ever since the launch of Total War: Warhammer, but even more since the arrival of Warhammer 2, I’ve been wondering if Creative Assembly has backed itself into a corner. ![]() From what I observe from my Razer and Logitech setups, their control software creates a virtual HID device that inserts the key macros or mappings on behalf of the hardware keyboard. For gaming keyboards, to get these keys, I agree with that you need an integration with the driver. I have a Sun Type 6 Unix which uses non-standard key codes on the HID driver for a set of keys to the left of the main QWERTY area.

Install is super easy, it's actually relaxing.Seems strange that there would not be a key assignment to the G keys how does the system know they are there ? Even IBM keyboards had added mappings. Took a few weeks to arrive, I highly recommend them. Ordered Black/White decals and it makes all the difference in the world.

Sure, a set of stickers costed more than the generic one, but, boy, the Keyshorts one deserves every cent. I then searched the internet for a set of stickers specifically tailored for my notebook, I found Keyshorts, and decided to give it a try. "Some time ago I bought a laptop on sale, the only downside being it having a spanish keyboard since I wanted a US keyboard instead, I bought a set of generic stickers, but the result was questionable at best: they were way too small for my keyboard, and they also were quite different from the original keys. Communication was absolutely great and productive so I can really recommend it. "I bought quite a special keyboard not fitting any regular stickers but they went extra mile to look in details at it and make highly tailored stickers to match it exactly. These stickers truly saved my working life, (.) the stickers are mat and not glossy which is actually WAY better cause they don't get finger prints on them and always look clean compared to the actual Mac keys. "I got a work Mac with a German keyboard and was struggling to do all my shortcuts as well as finding the symbols. The decals saved me from having to buy a new $100 keyboard. The decals were easy to apply and I had no difficulty getting used to the feel. I ended up putting them on all the keys so it would uniform. "I ordered these decals to cover the worn-off letters on my Mac keyboard.
