Adding epoxy divisions and therefore reducing the area available for heat transfer by ~18%, results in up to a 5x increase in heat transfer rate at a given superheat. This result is explained by examining the nature of the bubble nucleation, growth, and departure process. The addition of non-conductive epoxy imparts order to the resulting vapor and liquid flows, which helps draw cool liquid to the surface and promotes departure of nucleating bubbles. While less of the surface area is available to transfer heat, this spatial order enhances the ebullition cycle and also delays dry-out. Figure 5 shows with the addition of two and four epoxy divisions per centimeter (N = 2 cm−1 and N = 4 cm−1 designs), the heat transfer rates steadily increase as compared to the bare surface. The performance enhancement reaches a maximum at a Bond number of unity,  = 1, and then decreases for smaller Bond numbers (N ≥ 6 cm−1). As the Bond number decreases, two factors affecting performance arise. First, the pitch between the epoxy divisions becomes smaller than the nominal bubble departure diameter, and secondly, the effect of surface tension becomes more pronounced. For N ≥ 6 cm−1 bubbles grow to diameters wider than the pitch between epoxy divisions before they can depart. This impedes the counter flow of cooler liquid returning to the surface and disrupts the desired spatial ordering of flow fields. Additionally, for BoP < 1 the effects of surface tension on the bubble departure process is evident, where the non-wetted base area beneath a bubble can grow to the entire width of the copper section (see supplementary movies). This is particularly evident for the N = 12 cm−1 design, which has a Bond number of BoP = 0.13, and shows performance worse than bare copper. In this case, the reduction of area available to conduct heat and the adverse effects of surface tension have outweighed any potential improvements associated with ordered flows. A decrease in HTC and CHF of approximately 25% as compared to a bare copper surface is seen.

“If you look back at older homes, their garages had as much detail as the house itself. But many of the houses built in the ’60s, ’70s and ’80s just had siding on them and no detail. They were considered just a place to park the car.

In general, a polycarbonate helmet shell will be heavier than a composite shell. But a polycarbonate shell can also take quite a beating, as you will see in the Part 2 video, while a composite shell is usually destroyed in a crash.

In low-light conditions, things get even worse. Photos are full of digital noise and compression artefacts, and while toggling the prominent ‘AI’ option in the camera app does make the phone recognize the scene as ‘Night mode’, and does little to improve the actual image quality. The front-facing 8-megapixel sensor captures selfies with adequate amount of details, even though sharpness levels aren’t exactly the best. Of course, the ever-so-important ‘beautification’ feature is thrown into the mix too.

Bob Mansfield, then closely involved in the watch project, said that Ive’s role was to be “himself and Steve” combined. Yet Ive still had to make a case to Apple, and Mansfield recalled “a lot of resistance.” It wasn’t clear how the company would display such things in stores; there were also concerns about creating a divide between wealthy and less wealthy customers. (As Mansfield said, “Apple wants to build products for everybody.”) But Ive won the argument, and in 2013 the company announced the high-level appointments of Angela Ahrendts, the former C.E.O. of Burberry, and Paul Deneve, the former C.E.O. of the Yves Saint Laurent Group. Patrick Pruniaux, from tag Heuer, a part of the L.V.M.H. luxury conglomerate, was hired last year. Apple has announced that the cheapest watch will cost three hundred and forty-nine dollars. In parts of the world already filled with smartphones, that price may give the Apple Watch the graduation-gift appeal that, according to Brunner, Beats consciously sought with its headphone pricing. But Ive’s solid-gold models, innocently named Apple Watch Edition, are expected to cost many thousands of dollars. John Gruber, an influential Apple blogger, has written that the prices may be “shockingly high . . . from the perspective of the tech industry,” but perhaps “disruptively low from the perspective of the traditional watch and jewelry world.” Sebastian Vivas, the director of a watch museum maintained by Audemars Piguet, the Swiss manufacturer, recently described his industry as unperturbed by Apple’s plans: “We’re not afraid; we’re just a little bit smiling.” It would be a greater threat, he told me, if men widely accepted that they could wear gemstones without a time-keeping pretext.

Low Traction Launch is designed to help drivers pull away smoothly from a standstill on slippery surfaces. Activated through the infotainment system’s lower touchscreen, Low Traction Launch provides a very progressive throttle pedal calibration, assisting in reducing the possibility of wheelspin2. Above 18mph (30km/h), the throttle calibration automatically reverts back to the Terrain Response setting that was previously selected.

The Kurant Tap House opened this summer, with designs by JKRP Architects. It boasts a rustic-industrial look, with a concrete floor, exposed wood and brick, and wide windows. The finished applewood now sits as the top of the bar, varnished and shining. Right behind it, Meyers serves Kurant hard cider, a brand he formed only four years ago with his business partner Joe Getz.
