Current Entries --------------- 12/23/2022 On very smooth surfaces adding water can increase friction: https://physics.aps.org/articles/v15/196 "[T]he coefficient of friction (horizontal force divided by normal force) had its minimum value of 0.3 when the surfaces were completely dry. As the humidity increased, the coefficient peaked at 0.6 when the humidity was 20% and then slowly decreased as the air became more humid. For the fully immersed case, the coefficient was around 0.5, implying that the completely wet surfaces were nearly twice as sticky as the completely dry ones." 12/15/2022 Mammals may have originated in Australia: https://phys.org/news/2022-12-mammals-island-hopped-australia-colonize-world.html 12/08/2022 Disable some iOS 16 annoyances: https://gizmodo.com/ios-16-search-bar-notifications-mail-app-photo-changes-1849857452 12/08/2022 Long-Baseline News, November 2022 Edition: https://www.hep.anl.gov/ndk/longbnews/2211.html 12/08/2022 OverSight 2.1.3: https://github.com/objective-see/OverSight/releases/tag/v2.1.3 12/08/2022 Garden sink with integrated hose reel: https://www.core77.com/posts/117741/A-Garden-Sink-with-Integrated-Hose-Storage 12/07/2022 Blackstarting the power grid: https://practical.engineering/blog/2022/12/5/what-is-a-black-start-of-the-power-grid 12/07/2022 How JWST images are composited: https://www.scientificamerican.com/article/are-the-james-webb-space-telescopes-pictures-real/ https://static.scientificamerican.com/sciam/assets/Image/2022/saw1222Chri32a_d.png 12/06/2022 The last 747: https://www.thedrive.com/the-war-zone/the-last-747-ever-built-has-rolled-off-boeings-production https://www.thedrive.com/news/the-last-ever-boeing-747-has-been-built 12/06/2022 Cold and flu may be more common in winter because our noses immune response may not be as effective when our noses are cold: https://gizmodo.com/why-we-get-sick-cold-winter-nose-immune-response-1849859708 https://www.jacionline.org/article/S0091-6749(22)01423-3/fulltext#%20 12/04/2022 OverSight 2.1.2: https://github.com/objective-see/OverSight/releases/tag/v2.1.2 12/01/2022 The Don't Die Box: https://www.youtube.com/watch?v=Aw9M7dKV0oQ 12/01/2022 Walking on deformable surfaces, like dirt or sand, requires more work because one needs to "take longer strides, which in turn leads to increased energy use by muscles in the hips and knees": https://phys.org/news/2022-12-deforming-surfaces-energy.html Earlier Entries --------------- 11/##/2022 https://srirangav.github.io/motd/2022/11/motd.txt https://srirangav.github.io/motd/2022/11/index.html 10/##/2022 https://srirangav.github.io/motd/2022/10/motd.txt https://srirangav.github.io/motd/2022/10/index.html 09/##/2022 https://srirangav.github.io/motd/2022/09/motd.txt https://srirangav.github.io/motd/2022/09/index.html 08/##/2022 https://srirangav.github.io/motd/2022/08/motd.txt https://srirangav.github.io/motd/2022/08/index.html 07/##/2022 https://srirangav.github.io/motd/2022/07/motd.txt https://srirangav.github.io/motd/2022/07/index.html 06/##/2022 https://srirangav.github.io/motd/2022/06/motd.txt https://srirangav.github.io/motd/2022/06/index.html 05/##/2022 https://srirangav.github.io/motd/2022/05/motd.txt https://srirangav.github.io/motd/2022/05/index.html 04/##/2022 https://srirangav.github.io/motd/2022/04/motd.txt https://srirangav.github.io/motd/2022/04/index.html 03/##/2022 https://srirangav.github.io/motd/2022/03/motd.txt https://srirangav.github.io/motd/2022/03/index.html
