Maths (topology and stochastic analysis) & hiking (Utah)!!! What else?!
Scientists at Skolkovo Institute of Science and Technology have determined through mathematical modeling that the process of erosion optimizes the shapes of disintegrating materials.
Natural Erosion of Sandstone as Shape Optimisation:
https://www.nature.com/articles/s41598-017-17777-1.pdf
Natural arches, pillars and other exotic sandstone formations have always been attracting attention for their unusual shapes and amazing mechanical balance that leave a strong impression of intelligent design rather than the result of a stochastic process. It has been recently demonstrated that these shapes could have been the result of the negative feedback between stress and erosion that originates in fundamental laws of friction between the rock’s constituent particles. Here we present a deeper analysis of this idea and bridge it with the approaches utilized in shape and topology optimisation. It appears that the processes of natural erosion, driven by stochastic surface forces and Mohr-Coulomb law of dry friction, can be viewed within the framework of local optimisation for minimum elastic strain energy. Our hypothesis is confirmed by numerical simulations of the erosion using the topological shape optimisation model. Our work contributes to a better understanding of stochastic erosion and feasible landscape formations that could be found on Earth and beyond.

"To me, the thing about having a terminal disease, is, everybody knows they're going to die at some point," Barres says in the first video. "But to me the hardest part is this incredible time I've been having in science just comes to an end. There's all these questions I'm curious about, and I would be hiring new students and post-docs when I got sick, and I just told them all not to come."

At [ https://media.ccc.de/v/34c3-9064-the_ultimate_apollo_guidance_computer_talk ]. "While it might not be as exciting as the Saturn V rocket itself, the Apollo Guidance Computer (AGC) was one of the most important developments of the entire Apollo program. While comically underwhelming compared to modern hardware, the AGC was nothing short of revolutionary when it was developed in the 1960’s. Before the AGC, the smallest computers were about the size of a refrigerator and consumed hundreds of watts; both big problems if you’re trying to pack them into a relatively tiny space capsule with limited resources. Not only did the AGC get humanity to the Moon and back, but it also redefined the state of the art for microcomputers, paving the way for the desktop systems of the 1970’s.
That said, the design and operation of the AGC is downright bizarre to modern eyes; it comes from a time of limitations we can hardly fathom. With this in mind, [Michael Steil] and [Christian Hessmann] put together “The Ultimate Apollo Guidance Computer Talk” for 34C3.
This hour-long presentation walks viewers through every aspect of not only the AGC itself, but how it interacted with the Saturn V rocket and the overall lunar mission. Even if you aren’t enough of a vintage computing aficionado to appreciate the complexities of core rope memory, the presentation gives a fascinating look at the gritty details of one of humanity’s greatest achievements."

Samsung pushes out update to fix Galaxy Note8 LTE data interruption issue
Samsung has started rolling out a new update to its Galaxy Note8 flagship smartphone. The update doesn't change the build number (which remains at N950FXXU2BQKG), but it includes a fix for an LTE-related issue.
Specifically, the changelog says the update fixes intermittent interruption of LTE data. That's it. Aside from this, some other usual bug-fixes are also included. Reports say the update is currently hitting units in Taiwan - no information on if and when other key markets will get it.

IN Imperial #American #Chain Restaurants #Design there are three chain #restaurants would have space for #outside seating as well separate entrances into the building.The exterior façade of the #building was made from white stucco and natural stone elements. We also added red canopies which complimented the chain #restaurant #exteriors.

The Crepe Bechamel #Restaurant in #Doha, #Qatar features quite an exemplary #design that merges a fine-tuned traditional vibe with a distinctly #modern sensibility. Much of it comes from the well-crafted designs that have been done up in glittering brown and Marengo tones. The elegance and class of the dim, gold lighting is the best cherry on top of this #interiordesign.
