Fighter jet pilot demonstrates centripetal force, a concept that Isaac Newton discovered between 1676 and 1677. However, the concept of centripetal force was not actually discovered in a single event or by a single individual but rather evolved over time through the works of multiple scientists and thinkers. Here... is a brief history of the development of our understanding of centripetal force: Ancient Greece: The ancient Greeks, particularly philosophers such as Aristotle and later Archimedes, made observations and formulated theories about the motion of objects. However, they did not have a clear understanding of centripetal force as a distinct concept. Islamic Scholars: During the Islamic Golden Age, scholars such as Ibn Sina (Avicenna) and Ibn Bajjah (Avempace) made significant contributions to the understanding of motion. They discussed the idea of impetus, a precursor to the concept of centripetal force. Johannes Kepler: In the 17th century, Johannes Kepler, a German astronomer and mathematician, formulated his laws of planetary motion. Kepler's laws described the motion of planets around the sun and the concept of elliptical orbits. Although Kepler did not explicitly mention centripetal force, his work laid the foundation for later developments. Isaac Newton: In the late 17th century, Sir Isaac Newton, an English physicist and mathematician, published his groundbreaking work, "Mathematical Principles of Natural Philosophy" (also known as the Principia). In this work, Newton presented his laws of motion and the universal law of gravitation. Newton's laws, particularly the second law of motion, provided a mathematical understanding of centripetal force. He demonstrated that an object moving in a curved path experiences an inward force acting towards the center of the curve, which is now known as centripetal force. Further Developments: Following Newton's work, subsequent scientists, such as Jean le Rond d'Alembert and Daniel Bernoulli, expanded on the understanding of centripetal force in the context of mechanics and fluid dynamics. It's important to note that the discovery and understanding of centripetal force were gradual processes that involved the contributions of numerous individuals over centuries. The concept became firmly established with the development of Newtonian physics and its laws of motion.show more

The fascinating concept of Non-Newtonian fluids, which transition from a liquid state to a solid-like state when pressure is applied, has a rich history that spans several centuries. The study and understanding of these peculiar fluids have evolved over time, leading to a wide range of practical applications and scientific insights. One of the earliest references to Non-Newtonian behavior in fluids dates back to the 17th century when Sir Isaac Newton formulated the basic principles of fluid mechanics. Newton's laws of fluid motion primarily applied to Newtonian fluids, which exhibit constant viscosity and flow behavior regardless of the applied force or pressure. However, it soon became apparent that not all fluids behaved in this predictable manner. In the mid-19th century, a scientist named Thomas Andrews made significant contributions to the understanding of Non-Newtonian fluids. Andrews conducted groundbreaking experiments with carbon dioxide, revealing that under high pressure, this gas could transform into a liquid. This observation marked one of the earliest instances of pressure-induced phase changes in fluids. The term "Non-Newtonian" itself was coined in the 20th century to describe fluids that did not adhere to Newton's classical laws of fluid dynamics. These fluids exhibited a variety of behaviors, but one of the most intriguing was their ability to solidify or increase in viscosity when subjected to stress or pressure. One of the most famous examples of such behavior is cornstarch mixed with water, which forms a substance known as "oobleck" that becomes more solid when pressure is applied. In the modern era, Non-Newtonian fluids have found applications in various fields, including food science, engineering, and material science. They are used in products like quicksand, body armor, and even in the development of impact-resistant materials. One of the key insights that emerged from the study of Non-Newtonian fluids is the importance of understanding the relationship between stress and strain, as well as the influence of time-dependent properties on their behavior. This knowledge has led to advancements in rheology, the study of flow and deformation in materials, and has practical implications in areas such as industrial processing, medicine, and the design of everyday products.

For thousands of years, civilizations have preserved stories of beings who drank blood to prolong life—from the blood-drinking demons of ancient Mesopotamia, to the Lamia of Greece, and the vampires of Eastern Europe. The Bible states that the blood contains the life force: "For the life (nefesh) of the flesh is in the blood." — Leviticus 17:11 The consumption of blood is forbidden in the Old Testament. In ancient Egypt, this concept is associated with the life force known as the Ka. Today, billionaires have openly funded anti-aging research involving transfusions of plasma from young donors in the hope of slowing aspects of aging. Peter Thiel publicly expressed interest in parabiosis research—the idea that factors found in young blood might influence aging—while startups such as Ambrosia attracted widespread media

American Muslim scholar, Hamza Yusuf co-founder of the Zaytuna College declares that “the whole concept of an ‘Islamic state’ is a fantasy in the minds of the modern Islamists” & confirms that the vast majority of Muslim states in history were “secular” (see above post for what he means by ‘secular’). As I recently argued in my Oxford Union debate - which we won - the reading into Islamic sources of the modern idea of a unitary legal ‘state’ (dawlah) over all of society, is an anachronism. It is the retrospective imposition of the European Westphalian nation-state concept onto traditional Islamic sources. The word ‘state’ (dawlah) is entirely absent from *all* Islamic sources of Shariah. As is the word ‘law’ (Qānūn) and as is the word ‘constitution’ (Distūr). It is thus impossible for the term ‘Islamic State’ to be anything other than a modernist reading. And Shariah is not a ‘law’ (the concept of unitary legal system did not exist) so there is no such thing as ‘Sharia law’. There is only Shariah (which means ‘the way’). Islam did not define any fixed notion of state, and hence the matter is left to the people to adopt within Islamic parameters. Here is my recent 10 minute Oxford Union debate speech which explains further:

The Hidden Language of Diffusion Models paper page: tackle the challenge of understanding concept representations in text-to-image models by decomposing an input text prompt into a small set of interpretable elements. This is achieved by learning a pseudo-token that is a sparse weighted combination of tokens from the model's vocabulary, with the objective of reconstructing the images generated for the given concept. Applied over the state-of-the-art Stable Diffusion model, this decomposition reveals non-trivial and surprising structures in the representations of concepts. For example, we find that some concepts such as "a president" or "a composer" are dominated by specific instances (e.g., "Obama", "Biden") and their interpolations. Other concepts, such as "happiness" combine associated terms that can be concrete ("family", "laughter") or abstract ("friendship", "emotion"). In addition to peering into the inner workings of Stable Diffusion, our method also enables applications such as single-image decomposition to tokens, bias detection and mitigation, and semantic image manipulation

Did you know that the French and British invaded Beijing in 1860 in order to force China to legalize opium? British and French looted and destroyed the Old Summer Palace, a massive complex of gardens, palaces, and art. Hundreds of Chinese people were killed, and dozens of the most beautiful architectural structures in the world were looted and burned down. China has left the ruins as a reminder of their history, and as a record of the brutality of Western imperialists.

Faraday's Law of Induction ✍️ It describes the phenomenon of how a changing magnetic field around a wire can "force" electricity along its length. As the magnet is moved up and down through the wire coil, the magnetic flux (the number of lines of force) is constantly changing. This constant change leads to an electromotive force (EMF), which behaves like a battery, providing the necessary power for electrons to flow and generate electrical current. The video demonstrates that electricity is not produced simply by placing a magnet near the wire but rather by moving the magnet. The rate at which the magnet is moved dictates how much electricity is created. Nevertheless, as seen from the chart, the movement of electricity ceases completely when the magnet remains stationary, regardless of whether it is inside the coil. Video 📸: py6cj

Unfortunately, I noticed that CENTCOM released footage of the destruction of a historic fighter jet at the 3rd Tactical Fighter Base of the Iranian Air Force in Dezful. It was a decommissioned MiG-23BN of the Iraqi Air Force that had defected to Iran in 1991 and I was trying to have it transferred to the Iranian Air Force Museum in Tehran in 2012. However, the aircraft remained in Hamedan following to my arrest by the Iranian Ministry of Intelligence, and unfortunately this historic aircraft was destroyed today. This MiG-23BN defected to Iran in January 1991 during Operation Desert Storm, and it was one of the over ten MiG-23s that defected to Iran. Unfortunately, almost all of them were scrapped in Dezful and Hamedan and their wreckage were moved to Tehran, and the last one, which was supposed to be displayed in the museum, was finally destroyed by a U.S. Air Force MQ-9A drone in Hamedan. I also noticed that all F-4s of Shahrokhi Air Base had already been evacuated from the base to protect them from the threat of U.S. airstrikes. Therefore, what remained there was this historic MiG-23BN of the Iraqi Air Force, which was parked in one of the hardened aircraft shelters. I never managed to photograph it myself but I have a photo of this in my archive and I will release it. #OperationLionsRoar #OperationEpicFury

Exactly. While this is true, it’s also irrelevant in the grand scheme of things. Ross was at fault, period. Here’s why: First off, it’s against DHS policy & training for an officer to approach a vehicle from the front in this situation, and this “officer-induced jeopardy” negates the officers use of force claim and puts him at fault, period. There’s no debate on this as video evidence from multiple sources clearly show Ross stopping in front of her vehicle, and then taking the time to shift his phone from his right hand to his left so he can draw his weapon…BEFORE she even started moving. THIS is simply reality, and the conversation should end here. Second, it’s against DHS Use of Deadly Force policy (which is codified law) to fire at a moving vehicle that doesn’t pose imminent danger to officers, and even if they ARE in danger, it mandates deescalation before using deadly force, which EXPRESSLY states simply “moving out of the way” of a vehicle as a correct course of action before using deadly force (see attached doc below). Third, there is already well-established legal precedent governing these EXACT types of situations, and this officer would likely be found guilty by any jury in the U.S. For example: Adam’s vs. Speers (2020): “Once Speers was no longer in the path of the vehicle, the justification for the use of deadly force ended.” Orn vs. City of Tacoma (2019): “A reasonable jury could conclude that once Orn was no longer in the car’s trajectory, the threat of serious physical harm to him was eliminated.” Cordova vs Aragon (2009): “Where the officer had moved out of the way of the oncoming vehicle, the use of deadly force was not justified.” Villanueva vs. Cali (2021): “a reasonable jury could conclude that the Officers used excessive force, because they lacked an objectively reasonable basis to fear for their own safety, as they could simply have stepped back or to the side to avoid being injured.” Fifth, the videos/pics below CLEARLY show the officer was NOT in immediate danger, and the woman was moving away from him when he fired his FIRST shot when he was already clear to the left of the vehicle, and he fired the second & third shots point-blank into her face from the SIDE of the vehicle as she passed. That alone is enough to send him to prison, even if his first shot was somehow inexplicably deemed to be justified.

General Nicolas Torre was a breath of fresh air— a rare figure who shattered the age of protectionism and impunity long embedded within our ranks and society. As PNP Chief, he set an uncompromising standard in the administration of justice when he did what no one dared: arrest the once untouchable Rodrigo Duterte — the very man who mocked our laws and desecrated our institutions during and after his rule. General Torre proved, in both word and deed, that his loyalty lies not with men of power, but with the Republic and its laws.

Madain Saleh, also known as Al-Hijr, is a pre-Islamic archaeological site located in the northwest of Saudi Arabia. It is one of the most important archaeological sites in the Middle East and was designated as a UNESCO World Heritage site in 2008. Madain Saleh is a place of great historical and cultural significance, and it is a must-visit destination for anyone interested in the history and culture of the Arabian Peninsula. Madain Saleh was the second city of the Nabataean kingdom, which was established in 2nd Century BC. The Nabataeans were an Arab tribe who were known for their expertise in carving tombs and buildings out of rock. They were also skilled in agriculture, trade, and commerce. The Nabataean kingdom was centered in Petra, which is located in modern-day Jordan. Madain Saleh served as a strategic outpost for Nabataeans, and it was an important stop on the trade routes that connected the Arabian Peninsula with the Mediterranean world. Archaeological site of Madain Saleh covers an area of 13 square kilometers. It is located in a remote desert region, and it is surrounded by rocky mountains and valleys. The site contains around 130 tombs, which were carved out of the sandstone cliffs. The tombs are adorned with intricate carvings and inscriptions, which provide insights into the culture and religion of the Nabataeans. The most famous tomb at Madain Saleh is the Qasr Al-Farid, which means "the lonely castle." This tomb is located on a hilltop and is surrounded by a large courtyard. It is the largest tomb at the site, and it is considered to be one of the finest examples of Nabataean architecture. The tomb was never completed, and it is believed that it was abandoned after the death of the Nabataean king who commissioned it. Another important tomb at Madain Saleh is the Tomb of Lihyan son of Kuza. This tomb is located in the southern part of the site and is carved into a rock cliff. It features a large entrance hall, a central chamber, and a series of smaller rooms. The tomb is decorated with intricate carvings and inscriptions, which provide insights into the religious beliefs of Nabataeans. Madain Saleh is not just a site of tombs; it also contains a number of other important structures. These include the Al-Khuraymat and Al-Sabika temples, which were used for religious ceremonies and rituals. The site also contains a number of houses, wells, and cisterns, which provide insights into the daily lives of the Nabataeans. Madain Saleh was abandoned in the 3rd Century AD, after decline of the Nabataean kingdom. The site was rediscovered in the 19th Century by the Swiss traveler Johann Ludwig Burckhardt. Since then, it has been studied by archaeologists from all over the world. The site is now managed by the Saudi Commission for Tourism and National Heritage, which has carried out extensive restoration and preservation work. Madain Saleh is not just a site of historical and cultural significance; it is also a place of great natural beauty. The site is surrounded by rugged mountains and valleys, and it is home to a diverse range of flora and fauna. Visitors to the site can enjoy hiking and camping, as well as exploring the ancient ruins. Madain Saleh is a site of great historical and cultural significance, and it is a must-visit destination for anyone interested in the history and culture of the Arabian Peninsula. Ancient ruins at Madain Saleh provide a glimpse into the engineering and architectural skills of the Nabataeans, as well as their religious beliefs and cultural practices. However, as the site becomes an increasingly popular tourist destination, there are concerns about its preservation and the impact of tourism on the local environment. It is important that the Saudi government and local communities work together to ensure that the site is protected and that tourism is managed in a sustainable way. 🎥© Paris Verra #archaeohistories

Archaeological site of Madain Saleh covers an area of 13 square kilometers. It is located in a remote desert region, and it is surrounded by rocky mountains and valleys. The site contains around 130 tombs, which were carved out of the sandstone cliffs. The tombs are adorned with intricate carvings and inscriptions, which provide insights into the culture and religion of the Nabataeans. The most famous tomb at Madain Saleh is the Qasr Al-Farid, which means "the lonely castle." This tomb is located on a hilltop and is surrounded by a large courtyard. It is the largest tomb at the site, and it is considered to be one of the finest examples of Nabataean architecture. The tomb was never completed, and it is believed that it was abandoned after the death of the Nabataean king who commissioned it. Another important tomb at Madain Saleh is the Tomb of Lihyan son of Kuza. This tomb is located in the southern part of the site and is carved into a rock cliff. It features a large entrance hall, a central chamber, and a series of smaller rooms. The tomb is decorated with intricate carvings and inscriptions, which provide insights into the religious beliefs of Nabataeans. Madain Saleh is not just a site of tombs; it also contains a number of other important structures. These include the Al-Khuraymat and Al-Sabika temples, which were used for religious ceremonies and rituals. The site also contains a number of houses, wells, and cisterns, which provide insights into the daily lives of the Nabataeans. Madain Saleh was abandoned in the 3rd Century AD, after decline of the Nabataean kingdom. The site was rediscovered in the 19th Century by the Swiss traveler Johann Ludwig Burckhardt. Since then, it has been studied by archaeologists from all over the world. The site is now managed by the Saudi Commission for Tourism and National Heritage, which has carried out extensive restoration and preservation work. Madain Saleh is not just a site of historical and cultural significance; it is also a place of great natural beauty. The site is surrounded by rugged mountains and valleys, and it is home to a diverse range of flora and fauna. Visitors to the site can enjoy hiking and camping, as well as exploring the ancient ruins. Madain Saleh is a site of great historical and cultural significance, and it is a must-visit destination for anyone interested in the history and culture of the Arabian Peninsula. Ancient ruins at Madain Saleh provide a glimpse into the engineering and architectural skills of the Nabataeans, as well as their religious beliefs and cultural practices. However, as the site becomes an increasingly popular tourist destination, there are concerns about its preservation and the impact of tourism on the local environment. It is important that the Saudi government and local communities work together to ensure that the site is protected and that tourism is managed in a sustainable way. 🎥© Paris Verra #archaeohistories

How the 🆅🅴🅽🆃🆁🅸🅲🅻🅴 contracts.. . . . 💗Another great thing I picked up from Cardiothoracic surgery was understanding how the ventricles contract. The ventricle Is such a complex structure that we are learning more and more about. One thing that has helped us understand this complex structure is strain imaging and 3D echocardiography. We have learned that the ventricle contracts in 4 ways: contraction (radial) motion but it also has a twisting (torsional and circumferential) and shortening (longitudinal) motion. . . . 👐🏽The surgeon I always work with often described the hearts motion as “wringing of a towel.” This can be seen in the video above. The understanding of the multiple different motions of the heart has allowed us to better understand intrinsic myocardial disease and pick up disease earlier in its process allowing us to add disease modifying agents to slow and sometimes reverse the negative remodeling of the heart. . . . 💓So next time you think of your heart pumping don’t think of it in one motion (squeeze) but rather a Towel being wrung of water. The heart is such an amazing organ and we are just now really beginning to understand it’s truly complex physiology! . . . Have a great day! . . . . #Medicalschool #medschool #cardiologia #doctors #cardiotwitter #meded #EKG #Medstudent #cardiology #internalmedicine #patient #hospital #radiology #physiology #paschool #foamed #echo #physicalexam #anatomy #scrubs #surgery #pastudent #nursingstudent #nursing #PA #DO #Echocardiogram #MD #USMLE
