This may mean the beak, the feathers, etc. The depth of field of the lenses that you're using is often enough to get the whole head in focus. That will obviously include the eyes too. ... Focusing on a bigger object like the head will make keeping the bird in focus a whole lot easier. Focusing on the neck, depending on the type of bird, could also work[.]" @14:43 08/08/2025 Delta-Plutonium explained: https://phys.org/news/2025-08-plutonium-peculiar-behavior.html "Researchers from [Lawrence Livermore National Laboratory] demonstrate[d] a model that can reproduce and explain delta-plutonium's thermal behavior and unusual properties. The model calculates the material's free energy, a quantity that reflects the amount of available or useful energy in a system. ... Plutonium's electronic structure is among the most complex of all elemental metals because its electrons are easily influenced by relativity, magnetism and crystal structure. The new free-energy model accounts for magnetic fluctuation effects for the first time. ... Acknowledging those magnetic states in the theory causes it to match the odd experimental observations of contraction at high temperatures." @13:06 Older ----- 06/##/2025 https://srirangav.github.io/motd/2025/06/motd.txt https://srirangav.github.io/motd/2025/06/index.html 03/##/2025 https://srirangav.github.io/motd/2025/03/motd.txt https://srirangav.github.io/motd/2025/03/index.html 02/##/2025 https://srirangav.github.io/motd/2025/02/motd.txt https://srirangav.github.io/motd/2025/02/index.html 01/##/2025 https://srirangav.github.io/motd/2025/01/motd.txt https://srirangav.github.io/motd/2025/01/index.html ##/##/2024 https://srirangav.github.io/motd/2024/motd.txt https://srirangav.github.io/motd/2024/index.html ##/##/2023 https://srirangav.github.io/motd/2023/motd.txt https://srirangav.github.io/motd/2023/index.html ##/##/2022 https://srirangav.github.io/motd/2022/motd.txt https://srirangav.github.io/motd/2022/index.html Links ----- Text: https://srirangav.github.io/motd/motd.txt HTML: https://srirangav.github.io/motd/index.html RSS: https://srirangav.github.io/motd/rss.xml Validation ---------- HTML: https://validator.w3.org/nu/?doc=https%3A%2F%2Fsrirangav.github.io%2Fmotd%2Findex.html RSS: https://validator.w3.org/feed/check.cgi?url=https%3A//srirangav.github.io/motd/rss.xml
