Singular Value Decomposition is a matrix factorization that expresses a matrix M as UΣVᵀ, where U and V are orthogonal matrices, and Σ is diagonal. It can interpreted as the action of a rotation, a scaling and a rotation/reflection.

An anvil cloud (scientifically known as Cumulonimbus incus) is the flat, spreading top of a mature thunderstorm cloud. It forms when warm air rises rapidly, hits the stratosphere (a natural ceiling), and spreads horizontally. This is what it looks like from an airliner.

Today I discovered there is a bird known as Standard-Winged Nightjar. The male has wing ornaments called "standards" that grow out of the middle of its wings during mating season.

In Ghost of Yotei, you can eventually get a skill that allows you to summon the Wolf with your Shamisen. In the early parts of the game it happens at random but you can increase the chances by increasing your affinity, freeing wolf packs, and leveling the Wolf Skill Tree.

HIP MOBILITY - THREE moves to explore rotation of the hips. First one is seated where we can pry a little more having leverage to dive deep into internal rotation. Second is exploring IR rotation from a squat and third is a combo of the figure 4 contour and elevated pigeon.

Oral intubation, also known as endotracheal intubation, is a medical procedure that involves inserting a flexible plastic tube through a patient's mouth and into their trachea (windpipe). The tube keeps the airway open, allowing air to pass through and potentially connecting to a machine that delivers oxygen or air.

🇺🇦🙏 Border guards of the special unit "Dozor" filmed the moment of the successful rotation of their soldier with the call sign "Grinch" outside the kill zone. All covered in a swamp, exhausted, but smiling. One of the most effective ways to quickly deliver soldiers to or from a position is a quad bike trailer at maximum speed. Comfort is minimal, but the chances of survival are maximum.

Olive Tree of Vouves - the world’s oldest living olive tree is in Crete, Greece 🇬🇷 🫒 The oldest olive tree in the world is located in the village of Ano Vouves of Kissamos in Chania, Crete, Greece. The ancient tree is 3000 years old, as determined by the international scientific community. This tree likely lived through writing of Iliad (golden age of Athens), rise of Roman Empire, and birth of Christ; and then lived for 2000 years after that. It still produces olives, as well. The ancient olive tree in Vouves has a trunk with a circumference of 12.5m, and a diameter of 4.6m. It belongs to the local tree variety of tsounati and was grafted at a height of three meters onto a wild olive tree. Because of the grafting, its trunk has been so beautifully shaped by nature that it resembles a sculpture. In 1990, after a unanimous decision in the prefecture of Chania, the Vouves Olive Tree was declared a Natural Monument of great importance due to its status as the world’s oldest tree of its kind. The fruits of the ancient olive tree produce the best olive oil in the world, making the area the cradle of olive cultivation on the island of Crete. Trunk of the tree is now hollow as there is no heartwood, so the olive is renewed outward and the heartwood gradually rots away. Since the olive tree is constantly renewing its wood, it has served as a a symbol of immortality since ancient times. Thousands of tourists visit the stunning tree every summer to marvel at it and learn its history. They are mainly impressed by its enormous shape and the imposing volume of the trunk but also by the fact that it has remained alive and fruitful for 3000 years. The site of the olive tree, including the entire hill on which several villages are situated, has thousands of olive trees and the villages are widely believed to produce the best olive oil in the world. The olive tree has been associated with Greece for millennia. It symbolizes peace and prosperity, as well as the hope of resurrection and prosperous life. The typically Mediterranean Greek landscape is dotted with these trees, and Greeks throughout the centuries have been inextricably linked with this plant. For Ancient Greeks, the olive tree was one of two of the most respected mythical trees, along with the oak. The deeply rooted love and respect shown to this tree by Greeks has survived throughout the centuries. In ancient Greece, Olive Oil is known as “Liquid Gold,” as Homer called it, has been part of Greece’s history since antiquity. It is an irreplaceable nutritional component of the Greek diet. Ancient Greeks also used olive oil as part of their efforts to enjoy a healthy life and to promote longevity, and used it as a cosmetic for the skin and hair. Today, Greek olive oil is considered by most as the best in the world. The history of humanity’s use of the olive dates back to ancient history. In his work “Origine des plantes cultivées,” botanist Augustin Pyrame de Candole writes that our cultivation of the tree started some time around 4000 BC and that its origin is from the coasts of Asia Minor. Today, throughout the world, there are approximately 800 million olive trees of which approximately 95% are cultivated in the Mediterranean basin, which has best soil and climatic conditions for olive cultivation. The olive is widely grown all over in Greece. Its cultivation, which is greater than any other type of fructiferous tree, occupies approximately 15% of cultivated agricultural land and 75% of arboraceous cultivations in the country. 🎥© heygilber (IG) #archaeohistories

It is not known exactly why Mimosa pudica evolved this trait, but many scientists think that the plant uses its ability to shrink as a defense from herbivores.

There’s an old saying among aviators: every landing that you can walk away from, counts as a good landing. 🛬 And every landing that you can walk away from and the aircraft is still airworthy, counts as a great landing! 😎 📸 by ig/aviationxdreams
