⚾️ It is no secret that elbow injuries, specifically UCL injuries, have been on a rise in recent years ➡️ The reason for this is so multi-factorial that it is impossible to pinpoint any 1 reason for an injury 💪 With the constant improvement in the development of pitchers, both skill side and S&C, we are seeing an increase in velocity across all levels of baseball 🎟This is obviously a Great thing for Punching Tickets but also leads to more forces being passed through the medial elbow 🔥There are really 3 proactive actions we actions we can take to counteract this: 1) Address pitching mechanics if there are deficiencies 2) Appropriately manage chronic/acute AND Total workloads 3) Increase the capacity and stress the elbow can handle 🔥 We will specifically dive in to the 3rd component of this in this thread. In short, the answer is simple, GET STRONG FOREARMS 3 WAYS VALGUS FORCE IS DISPERSED ✅ Radiocapitellar Joint Compression When a valgus stress is applied to the elbow, it is attempting to open up or gap the medial (inside) portion of the elbow. This is also the Orthopedic Test for a UCL injury. While this force is trying to gap the medial portion of the elbow, it is also compressing the lateral side. When the radius and lateral humerus compress, this acts as a stopping point for the elbow going into that valgus motion ✅ Forearm Musculature In addition to the UCL on the medial side of the elbow, there is also a group of forearm muscles that span that area and attach to the same portion of the elbow, the medial epicondyle. These muscles include: Pronator Teres, Flexor Carpi Ulnaris, Flexor Carpi Radialis, Flexor Digitorum Superfiscialis, and the Palmaris Longus. With that specific attachment to the medial epicondyle and their respective distal attachments, these do a great job of accepting the valgus force and protecting the UCL. There is some research that states FCU does the best job of the muscles listed, but we believe the best action is to strengthen all of them. The best ways to attack this is with movements including: finger flexion, wrist flexion, Ulnar deviation (moving pinky towards medial elbow), and Pronation of the forearm ✅ Ulnar Collateral Ligament (UCL) What doesn’t get absorbed by the first two structures is placed on the UCL. Previous research has shown that a UCL with no other structures involved is able to withstand ~35 nm of force before failure The Problem is: Every Pitch produces far more than 35nm of Valgus Stress. This shows us just how important the other 2 mechanisms are! * Exercises in the videos should be a complement to your entire S&C Program and is not designed to replace it

Yesterday at Brown University ICERM's workshop on “Agentic Scientific Computing and Scientific Machine Learning” I spoke about “Adaptive Swarms Across Scales”, making the case for scientific AI as systems that can create representations, stress them, fracture them, and enlarge the category in which future representations live. The category here is a composable and breakable working universe of science: data, hypotheses, simulations, measurements, tools, failures, figures, papers, provenance, and the transformations that connect them. Discovery happens when those transformations become executable, inspectable, composable, and capable of changing the world model they operate within. Atomistic modeling gives one category - states, forces, trajectories, observables, boundary conditions, conservation laws. Neural surrogates learn fast morphisms inside or between such categories. But discovery is higher-order: it changes which objects and morphisms are available in the first place: what variables exist, what operations are allowed, what evidence counts, what scale is active, what invariant is being preserved, and what kind of explanation the system is even capable of forming. This is scientific method as adaptive architecture: compression, stress, fracture, recomposition. Fracture matters here because it makes the logic physical: a non-commuting diagram realized in matter. The imposed load, material hierarchy, defect field, and assumed continuum description no longer map cleanly into the observed outcome. The crack is the obstruction and it identifies where the old morphism failed and where a new representation must be introduced. The physical crack and the categorical obstruction are the same event viewed in different substrates. ScienceClaw × Infinite is a machine for constructing and transforming a category of scientific artifacts. Each artifact is typed. Each operation has lineage. Each failed branch remains in the category as reusable structure. The “paper” is no longer the terminal object of science; it is one projection of a larger compositional trace, and it can be generated at any time for consumption by a human or an AI. With that the unit of scientific labor is changing. For most of the twentieth century the unit was the result (a measurement, a theorem, a synthesized molecule). It is now becoming the algorithm that produces results, and after that, the substrate of discovery itself. The static PDF is the wrong terminal object for this regime, and the role of the scientist with it. We now design algorithms that build algorithms, and eventually substrates in which such algorithms compose themselves. At that point, the scientist is no longer outside the discovery system. The scientist becomes one of the representations the system can transform. In that sense, the systems will eventually do science to us, and that is the structural consequence of the principle they are built on.

Scientific research revealed that almost all bowling actions contained some degree of straightening at the elbow (referred to in these Illegal Bowling Regulations as “Elbow Extension”). In theory, therefore, the vast majority of bowlers, with actions considered by umpires to be legal under the Laws of Cricket, were contravening Law 24(3) each time they delivered the ball. It was also demonstrated in studies by human movement specialists that such Elbow Extension in a bowling action became noticeable to the naked eye – and started to look like a throw – when it exceeded 15 degrees. In order to ensure that the intention behind Law 24(2) was upheld and that the distinction between bowling and throwing the ball remained, the ICC has introduced regulations stipulating a maximum degree of permitted Elbow Extension in a bowling action. As with other regulations and Playing Conditions issued by the ICC, these Illegal Bowling Regulations modify the Laws of Cricket as applied to cricket played under the ICC’s jurisdiction. An Illegal Bowling Action is defined in these Illegal Bowling Regulations as a bowling action where a bowler’s Elbow Extension exceeds 15 degrees, measured from the point at which the bowling arm reaches the horizontal until the point at which the ball is released (any Elbow Hyperextension shall be discounted for the purposes of determining an Illegal Bowling Action). According to the Suspect Bowling Action procedure, delivering the ball without elbow extension is acceptable. Key Factors Elbow Flexion Angle (Degrees) - Upper arm horizontal ( Max - Min ) - Ball Release - Elbow Extension Note :- 4.1.2 in the event of a Player being reported during a Match in a Major ICC Event, the Independent Assessment shall be carried out on an expedited basis. Accordingly, unless exceptional circumstances exist, the Independent Assessment shall be carried out within a period of 72 hours from the time of the ICC’s receipt of the Match Officials’ Report;

Did Fortnite REVEAL a HUGE Retcon⁉️ When rewatching the official Fortnite Story Recap, something strange appears. The Loop Bubble is shown popping from Fracture and transitioning DIRECTLY into the result of the Big Bang, with this sentence being spoken as it happens: - "The Conflict ended with the Zero Point shattered and strewn across all realities" 💥 This line comes directly after Jones' explains the IO vs Seven War, which took place throughout Chapter 2 & 3, with Fracture finishing off the storyline. This "conflict" did NOT continue into Chapter 4...and not a single line was spoken about the events that took place in that chapter, or Jones' time travel leading to the Big Bang. While Chapter 5 wasn't shown either, the difference is there really isnt anything on a big enough scale that happened that chapter except for Hope's introduction that would need to be shown to us for the overall storyline to make sense...but Jones' being the cause of the Big Bang was a pivotal plot point. This begs a seriously huge question -- Did Fortnite retcon Chapter 4? 💭 I know this is automatically going to be a scary topic for people, but I think this is VERY important to discuss since this is the FIRST EVER official Storyline Recap we've received from Fortnite, and they specifically didn't acknowledge how the Zero Point ACTUALLY shattered - Jones traveling back in time. We all know Chapter 4 was all over the place with unfinished plots, and also didn't arrive to us as intended due to developmental issues at Epic during this time. If we take a second to even entertain the idea that Chapter 4 "didnt happen"...it could actually work nicely. 💡 The Herald and The Last Reality succeed in their plan of destroying the Zero Point -- they shatter it in Fracture. This causes a HUGE Big Bang to occur, reorganizing everything and sending Shards of the Zero Point across all realities. Jones arrives to Hope's Home Reality after Fracture, and the Shard Storyline begins from there. ☄️ This takes out a huge unnecessary gap of time, when really nothing much happened. The Shapeless Man storyline was abandoned (for now), MEGA didn't do anything but lead to Wilds, which reintroduced Slone (we'll get to this in a second), and Last Resort was entirely themed after getting the Time Machine for the Big Bang, with Kado Thorne dying the same season. I ALSO would like to mention that Jones was quite literally absent the ENTIRE Chapter except for the end...our main character of the storyline. As you can see, nothing of importance to the overall plot of the Storyline ever occured this Chapter except for the dead-beginning, except for Dr Slone appearing later on, which could now easily be revisited in MUCH better ways...🌌 If Chapter 4 is retconned, how could the Shapeless man & Doctor Slone be used again? It's simple. For Doctor Slone, we have no idea where she's even been since Big Bang. She appeared briefly, helped the Island escape a full-reality collapse, and then has been MIA since Big Bang. They can return Slone however they'd like, because it really doesn't make much of a difference between us having last seen her in Collision, or in Last Resort. Her interactions with Jones in OG are the only important pieces, which I feel like they could still never reference given the interesting relationship those 2 characters have anyway. Perhaps all of these years without the Imagined Order has unclouded Slone's judgement, so she acts friendlier to Jones when they reunite again, just as they did in the original OG. 🤝 As for the Shapeless Man, he was introduced & teased by Rift Warden Stellan, but never actually arrived in-game, or was referenced...ever again. If (or when) the Shapeless Man does appear again, Epic could really do whatever they want given how little we know about this character in the first place. If it's Geno, it's truly as simple as just reestablishing Geno back into the Storyline in modern day. The Shapeless Man doesn't need to ever be referenced again, because we can assume it would've just been him working in the shadows anyway if thats what they intended. 🏰 I know this is very out of nowhere, but the order of events they described in the OFFICIAL Story Recap felt very intentional, so I wanted to touch on this idea that they perhaps decided Chapter 4 is better off retconned. ALL of the characters introduced this chapter would still exist, including the Triarchy, the Ancients, etc, because they all exist out there in the Omniverse. The "retcon" would purely be that the Island never occured -- Fracture shattered the Zero Point and restarted the Omnniverse, all to The Last Reality's plan. 🛸 Things that would no longer have happened: - Zero Fusion + Paradigm's "Sacrifice" - AMIE leaving in the Rift gate, lines about the Seven being "Sculpted Anew" (lines up with The Order's sudden appearance, and the way she talks about the Seven) - Slone's Return in Wilds - Kado Thorne's death - Jones travelling back in time - Big Bang caused by Jones Things that WOULD still have happened: - Events of early Oathbound + Stellan's hauntings, just in their home reality - Some of the Seven being in possession of TLR, since this happened in Fracture - Triarchy and other characters still exist, just weren't dragged into Asteria - Unseen + Nox invading MEGA City and wiping TLR database, just in their home reality instead - *Possibly* Slone's character arc, just off-screen wherever they want her to have been - Kado Thorne's Time Machine + messing with the past Let me know your thoughts (respectfully, please! I know conversation regarding retcons can get some people angry). Nothing is confirmed, this is just speculation. 🙏 #Fortnite #FortniteSeven

SOMETHING PUNCHED A HOLE THROUGH FROZEN LAKE 10,000 likes. 29 comments. Filmed from a helicopter door over an ice sheet. Something drops, the ice opens in a small red-lit circle, cracks race outward, and a column of water blows straight up through the hole the cracks are what sells this, and they are the one part that is hard to fake: → they radiate from the impact point in a spoke pattern, which is what brittle sheets actually do under a point load → the spacing is irregular. real fractures branch unevenly because the ice is not uniform, and evenly spaced cracks read as decoration immediately → they propagate outward over time rather than appearing at once. fracture has a speed, and showing it is what makes the eye accept it → secondary cracks split off the main ones at sharp angles instead of curving, which is correct for ice and wrong for glass or mud → and the plume comes after the fracture, not with it. pressure needs the hole before it can use it that ordering is the whole trick. a convincing destruction shot is not about how the damage looks, it is about the sequence the damage arrives in, and sequence is the thing a still image can never carry which is why this category of clip keeps outperforming much more elaborate work. no character, no dialogue, no continuity to protect. one event, shown from cause to consequence, in the correct order the useful takeaway for anything you make: find the shot where the physics does the storytelling, and get out of its way. the viewer is not evaluating the render, they are checking whether the world behaved ten thousand likes on twenty-nine comments says nobody argued with it, which for this kind of clip is the result you want if you want to test a single-event idea before building anything around it, image-to-video off one still is the cheapest way in. Picsart runs it from a phone the hole is the easy part. the order the cracks arrived in is what convinced you
