Veritasium’s Post

Last semester (Spring 2024), I did an independent study with Dr. Basaran, where I used Unified Mechanics Theory to determine the fatigue life of a steel bridge beam. The final presentation is available in this post.

New blog on the subject of aerostructural fatigue, going a little bit into the weeds of fracture mechanics but also containing practical downloadable guidelines

Closely related to each other, the Hamilton-Jacobi-Bellman equation and Pontryagin’s Maximum Principle were two of the most important pillars in Optimal control theory. In this article, we provide a pathway to derive PMP from HJB under some mild assumptions, showing the connections in between, and most importantly, revealing the beautiful structure of optimal control problems. Inspired by Huygens-Fresnel principle, two toy examples were also provided, each tackled from different aspects to demonstrate potential challenges for each method. #Controlsystems #OptimalControl #Physics

This talk introduces unpublished modeling patterns designed to elegantly handle causality between Bounded Contexts while minimizing coupling. If your system is or is becoming modular, these patterns will prove valuable to preserve your teams' autonomy. Watch https://buff.ly/4fjouPa and join us again next year!

Newton's Cradle Proof To simply put in a Nutshell, the very moment the body hits the other one there is exchange of velocity and the same is replicated by the body when it comes back in reverse direction.The below is a theoretical proof,a 11th Grade Version of of it. #Physicswithmeaning

Suppose a person in moving in a train with a constant velocity towards an observer. How can one infer that the object which is moving is the train and not the whole world in backward direction. We all know that motion is relative. But what does it mean??? One needs to have a logical answer to that question. Suppose you want to find the answer to the question mentioned above. There are various experiments which we can try... let us suppose it is an ideal train... the tracks are ideal and no air resistance to reduce speed . The first thing which you can try is throwing a ball in the air while inside the train... if you move ahead while the ball falls behind, then the train is definitely moving. But practically it does not happen. Due to inertia, the ball falls in the hands and this again shows that the train is at rest while the world is moving. Similarly, we can increase the speed of objects and throw them in front. If the object appears to be at rest as compared to the train, then we can conclude that the train is indeed moving as the object thrown is clearly not at rest. But all the objects again will carry inertia which will always be going away from the person throwing the object thus failing the experiment. Thus, it is clear that if the object is moving with constant velocity, we can never prove that it is the object which is moving and the whole world is not moving using Newtonian mechanics. Hence we conclude that motion is indeed relative.

A recent article argues that the “universe’s topology may not be simple.” (1) More simplistically, we may be seeing reflections that make the universe appear much larger than it really is. This makes sense and it may provide further impetus to the simulation hypothesis. More generally, it throws much of what we thought we knew about the universe into question. First humans looking into the heavens may have thought about this. It was impossible to envision a universe as huge as the status-quo expectation. It would have been a waste, especially if “God,” created such a system for her creations on Earth to see and enjoy. Any level of optimization would have naturally led to a geometry that loops in and provides an impression of huge size. She apparently put the Earth at the center of the universe (well, just like anywhere else), and then provided a mirror trick to make humans believe in her power. As they say, “they do it with mirrors.” (1) Physics — The Universe’s Topology May Not Be Simple (aps.org)

Supermassive black holes can expel jets of material so vast and powerful that they may shape the large-scale structure of the cosmos https://trib.al/pcXcoU9

As Above, so Below…if this is the case then what is in the video on my last post is also this. I did this sketch last year when studying “sacred geometry”. The equation is just for me, it is obviously not from a “Physicist/Mathematician”; but is the best way for me to currently understand the “pattern” of what MAY be occurring. This may also be a starting map to the natural energy and “magical” fields around our Planet and others that spin and “suck in” energy to their cores. It could also just be a silly drawing! ✌🏼😊
