In addition to spatially ordering the escaping vapor and returning liquid flows, the epoxy divisions promote the coalescence-induced departure of laterally merging bubbles. Figure 4a shows the coalescence of two ~2 mm bubbles bridging over an epoxy division. As the two bubbles merge the underlying epoxy division between them remains wetted at all times. A thin liquid layer remains on the cold epoxy surface and the non-wetted base areas below each bubble do not merge, collapse, or otherwise move during the entire process. The resulting bubble deforms due to surface tension and is quickly ejected from the surface. The low temperature epoxy inhibits the inward lateral merging of the non-wetted bases, and helps draw replenishing liquid underneath the bubble thus promoting departure. Conversely, Fig. 4b shows time lapse imaging during pool boiling on bare copper surfaces at a comparable heat flux, where three distinct lateral coalescence events are visible. During the 36 ms movie several bubbles are seen coalescing laterally, and in each event the non-wetted base areas merge inward and the resulting bubbles do not depart. The result is a new non-wetted base area beneath the larger coalesced bubble that is still attached to the surface. While this high-speed imaging is conducted at relatively low heat fluxes, it does provide insight into the mechanism driving boiling enhancement on bi-conductive surfaces. The behaviors visualized at low fluxes, along with the pool boiling results shown in Fig. 3, can be used to draw conclusions regarding the nature of enhancement across all boiling regimes up to CHF.

M.M.R. and M.M. conceived the project, reduced and analyzed the data, and wrote the paper. M.M.R. and J.P. fabricated the samples and conducted the experiments.

How well does it work? Given that it’s a very difficult problem to solve, remarkably well. Rain and wetness is an especially difficult issue. Water is an excellent conductor and water sprayed or falling onto a touch screen will completely mess up measuring capacitance between electrodes. So the L10 may provides wet touch functionality by significantly decreasing the sensitivity of the touch controller and using a special screen protector that makes water pearl and bead enough so that there isn’t uncontrolled conduction between different parts of the display surface.

We have commented on the Nolan finish several times in our reviews; the Hi-Brite finish has a very hard and protective feel and we wish all helmets used it. The surprising fact is that this is a water-based formula that was developed by Nolan with the paint supplier.

The range is available in a choice of six contemporary colours from ‘subtle’ white, cream and greyed cedar, to traditional oak and ‘dramatic’ anthracite grey and wine red, all with a 10-year guarantee.

As always with Windows devices, we used PassMark’s BatteryMon utility to measure power draw on the high-end Core i7-8650U version of the L10 with the 1,000 nits screen.

Clive Grinyer visited Cupertino in the mid-nineties, before Jobs returned. Ive “was detailing printer lids,” he said. “He was close to leaving. And, good Lord, if he had actually left, the world would be entirely different.” Recalling this time, Michael Ive said, “Part of me thought, Oh, good, we’ll see him at home again.” Jonathan Ive has little appetite for discussing this period. He worked so hard that Brunner worried about his health; his designs—notably, the second iteration of the Newton personal organizer and, later, the Twentieth Anniversary Mac—were, in Brunner’s admiring description, “somewhat expressive, but still fairly tight and fairly crisp.” At the start of 1996, Brunner left Apple for Pentagram, the international design firm. He recommended Ive as his successor, but, later, he also tried to tempt him away. “I would have loved to have him as a partner at Pentagram, and I told him that,” Brunner said. “But he was ‘I’ve got to wait this out and see where it goes.’ ”

The worktables are higher than a desk but a little lower than the Apple Store tables they inspired. This height—arrived at after much reflection—accommodates seated study and standing visits. (Risking self-parody, Ive later referred to the “simplicity and modesty” of the arrangement.) Samsung Electronics sells vacuum cleaners as well as phones, and employs a thousand designers. Apple’s intentions can be revealed in one room. Each table serves a single product, or product part, or product concept; some of these objects are scheduled for manufacture; others might come to market in three or five years, or never. “A table can get crowded with a lot of different ideas, maybe problem-solving for one particular feature,” Hönig, the former Lamborghini designer, later told me. Then, one day, all the clutter is gone. He laughed: “It’s just the winner, basically. What we collectively decided is the best.” The designers spend much of their time handling models and materials, sometimes alongside visiting Apple engineers. Jobs used to come by almost every day. Had I somehow intruded an hour earlier, I would have seen an exhibition of the likely future. Now all but a few tables were covered in sheets of gray silk, and I knew only that that future would be no taller than an electric kettle.

On Friday, hearing complaints of roaches stirred up by the renovations, Councilman Johnny Streets emailed the city manager, city attorney and others:

Projecting an image from the floor would not produce an image most would call ‘large’ – as an experiment, take your current projector, put it 29″ away from the screen and tell me how “large” your projected image is.

Houstonia readers’ interests this year seemed to align with market trends, as some of our most popular real estate stories involved buying a home post-Harvey and 100 Carnarvon Drive, the ultimate in luxury real estate. Two of our guides—March’s Top Neighborhoods and November’s Architecture A-Z—also topped the list, as did a whole slew of virtual home tours, proving one thing true in 2018: Y’all really like to see how other people live.
