Enlightening lecture. I feel inspired to contribute to the rapidly evolving field of cancer mechanobiology.
when you say calculate the total energy @40:50, do you mean an SCF calculation?
Thanks so much for sharing this Sam. I love listening to scientists who love what they study and just deliver talks like this so the rest of us can love it too. If human beings are to appoint matriarchs to exercise guardianship over the sky, you should be one of them.

Excellent presentation. Thank you. The issues with the commercialisation of space need to be better recognized. It's really sad that they're already damaging science.
Thankyou

I appreciate your presentation. So excellent
Socio-economic collapses that would occure after a nuclear exchange are far, far more tangible than the largly unproven theoretical effects of so-called nuclear winter. The threshold for socio-economic collapse might be as little as one bomb detonated over a major financial hub. However, assuming that the nuclear winter theory is ever becomes grounded in scientific fact, one could assume that, in a time of political crisis, there would be a tremendous temptation to use nuclear wespons first, and to maintain that use level below the threshold of initiating nuclear winter while achieving the desired outcome against one's adversary.
It appears interesting and worthy of study. Although I am not a study of quantum. Thank you
Brilliant talk.thanks for caring to share your profound wisdom.
Sir I have a question. In your exp Rb fisrt increase then decrease. But in some case it remains constant over pillared hydrophilic surface. I am still confused why it remains contant over stuface
Is Berry phase imaginary quantity?
well, the berry phase angle phi itself is real, but usually you talk about a phase in terms of the exponential function, exp(i phi), which carries the imaginary number i=sqrt(-1).
This is amazing. So, hippocampus starts the spindles, then thalamus, then cortical wave? Fascinating that hippocampus plays back patterns to cortex sped up and sometimes reversed. I also liked the idea of the oil analogy of a snapshot holding a time window of information. I have wondered whether hippocampus dorsal-ventral traveling wave has any role in guiding cortex in a flowing time window for working memory. Also, what did you mean by "noise" is actually other systems (sensorimotor, auditory) when present in, say, visual cortex region? Would that suggest a global service required of each region, to use its spatial location to align the timing representational requirements of other modalities in accordance with where the traveling wave was?
Are you worried that signals can affect hearing ringing ad advancement in sonic weaponry here what the outcome could be especially when quantum physics and sting theory used in a way to torment or control people the fact is rumors of blue point projections are synthesized and I know the soul is real god is as well and transfiguration or Astro projections or transformation of information can be done by meditation and tekel a word used in the book of Daniel to think or can you hear yourself think all of creation and life has a spiritual signal dressing including water it’s all energy there is a god and they aren’t our kind and we haven’t all become born again and live and treat each other as our soul and lives depends on it and be wise on cause n effect in what we do in all walks of science such as in life we can create to heal or we can create to destroy this isn’t what was intended for life we are created for enjoyment and faith to trust in Christ but yet manny trust themselves to live with out reading or being taught by the most important teachings ever recorded in history I pray we all do god bless

To get to the Sturm‐Liouville formulation for a plausible set of boundary conditions, we make an adjoint connection between a change in latitudinal forcing with a temporal change: δξ/δφ=δn/δt δt/δφ
It is possible to manipulate the optical lattices with some electromagneic field in order to study quantum decay?
Today I am going to show we can find everyday black holes and wormholes. The key to remember is that quantum physic comes in two parts; a deterministic system called the Shrodenger equation and the 2nd part is the measurement. Also there is the page curve that corresponds to these two systems. One simple example of blacks holes and wormhole example is to clap your hands and listen to it. The actions of clapping your hands is the computed actions which takes place starting from the A-lattice microtubules to the motion of the clapping hands. The palm of your hands is the tools' tip. This is the first part of the quantum physic which is the Shrodenger equation. It's a quantum computer. The problem with any computer it going to use energy and creates byproducts which lingers around. Think of the 1st computer which have logic switches as huge gears and punch cards. As those logic gears and punch cards moved to the computed logic its joints and bearing begin to cause friction and heat and particulates. Those particulates begin to contaminates more moving parts causing a so called a black hole firewall. Since a computer operates on the idea of logic and causality the contamination and defects to a logic switche is really the asymmetry of causality. This is why you get this superposition of cats dead and alive at the same time but here we get two opposing blacks holes. In other words no one knows if this quantum computer is working or not. Maybe one of the logic switch seize up or jams. Here where the causal logic said if I throw a rock at the window the window should break. But the asymmetry to that is that not always the case. The true case is actually when you look at it. If its did not go as the logic said it must be defect in the logic circuit. Lets go back to clapping your hands example. You clapping your hands to produce sound. That sound or compressed air is the product of the computed actions. Its also the boundary. After the product is now we enter the 2nd part of quantum physic which is the measurement. Here is just the feedback system which is made of interconnected sensors, detectors, receptors, which is our ears and connect to the B-lattice microtubules. Once you hear the clapping sounds you should think of it as the blacks holes is transforming into a wormhole. That is a closed loop. But what if you don't hear the clapping sounds as expected? That means you have a defect within the two systems. You go back to explore the circuit or wormhole to find the defect or sometimes contamination. Once you fixed the bad part you preserved causality logic or information is recovered.
Elon Musk once believe that the universe is a computer simulation but now he doesn't. It seems that the more you use computer simulation for a self driving car is the more the car get stuck in the local maximum. It's unable to understand the real world driving due to the lack of human input and teaching of real world edge cases. Tesla self driving car now uses 4D simulation combined with live images from the environment by multiple cameras to form its sensory perceptions of vision. That is very close to how the human vision work. When the human mind use 4D of Relativity physic to simulate we get stuck in this mind simulation. We think that the universe has only 4D. If that is the case we will never can check our mistakes and fixe anything. We be like stuck inside a movie. But that not true if you play the movie back and forth long enough its going to break down in terms of wear and tear and glitches. No deterministic system can survive this constant punishment by the 2nd Law of Thermodynamic. We can also say that Alice is really dead inside a black hole. The more a physicist creates theories the more he get stuck in a black hole or his mental simulation. The black hole just get stretched longer and longer but never form into a wormhole. The black hole is building a bridge to nowhere. The problem here is that there is no measurement or observation to be made. Where is your tool of measurement such as cameras, sensors, detectors, and so on. And if you have those how come it haven turn on? Imagine in the LHC you take an action to push the button to fire up the particles accelerator and yet you don't have any detector to capture the product or Higs particulate for example. Then you really haven't make measurement or observation. What ever you are doing you are stuck in your 4D mental simulation. You need to figure out how to get out this blacks and into a wormhole and wise versa.
To whom that may be watching: I'm eager to know why the P-MOKE configuration is the most sensitive out of the three basic types of MOKEs? from my experience P-MOKE is indeed much more lenient to nonideal setups, though so far i cannot understand why, for P-MOKE signal can be derived in the exact same way as the L-MOKE signal.
Lets trace the measurement part of this close system. When we look at the final product we collapse the wave function. Now we no that the product/ theory exist although the product may or may not pass the spec. It didn't pass the spec due to two things. Its either has a defect and or a contamination. Since the product is actualized we can goes back or trace back to explore the wormhole. We can search what process machine causes the problem/defect/contamination. But that going backwards. We know that the bottom of a black is were we begin to look at the final product. When we folded a piece of paper above the place at which it is folding represent a sensory feedback in which light reflected of the surface of the product/boundary and into the observer eyes. Hence anything that has to do with our 5 senses. Or from the many sensors toward the microtubules B-Lattice. This is where the two superposition black holes fire up and form a wormhole. That is what we called sensory perceptions/observation/measurement/entanglement. Our mind/gravity switches from computation in the 4D to measurement in a 10D according to the Page Curve. The computation/actions/black holes is blind to the outside world or it could be blind outside of itself like a pure computer that can not see itself. To see its own self or its own actions it must switches to observation/measurement mode. A human reaction to the observed environment is 200 milliseconds. The computed path takes 100 milliseconds or the 1st half of the Page Curve and the other 100 milliseconds is the observation part. Or we can say that we loose information for 100ms while we recovered information in the next 100ms. Takes one step and look but don't blindly takes 1000 steps and look.
Netta Engelhardt did a good job on coming up with the two blacks hole and one wormhole. But these drawings can be improved farther by having space as a folded paper in a a C-shape. The two opposing blacks can be drawn so that their bottoms almost meet each other. When the gap stay open you get two blacks holes. During this time you activate only microtubules A-lattice. This is when your mind is thinking, computing, theorizing, and even taking actions to move the hands and fingers. If you push a 3-D printer the printer is said to be part of the process. If you push a factory to make a car the factory is part of the process. Thus the whole process starting from A-lattice to the last tool tip is just one processor or one computer doing the actions to make a product. The product which is the result of this massive computation can not be actualized until the inventor of the product look at it. The product at this point stay as a theory in the upper black hole. How many dimensions is this black has? A theory exist as simulation in the 4D. Our usual 4D relativity physic. So if you move your hand now you are activating the upper black hole. But you can crash into obstacles if you don't activate your sensory feedback. Your sensory feedback is when you look at your hand or the product with your own eyes live. Your 5 senses when activate will close the gap between the two black holes and turn them into a wormhole. Thus the thing that closes the gap between the two black holes is entanglement or information outside the theory. Remember the theory lives in the 4D as simulation but once you enter the wormhole its goes up to 10D. So if you look at your invention as it finally come out of a factory..What do you see? Does it matches the theory? According to Netta Engelhardt we must force/demand that it matches so that unitary can be preserved. Sure this might work if there is no obstacles in the way. This would be a complete ignorance to 2nd Law of Thermodynamic. There is no such thing as complete isolation. Every action produces heat and friction and every friction produces particulates and contamination and every contamination produces defect. After a long manufacturing processes your invention such as a computer chip will most likely not fit the theory. There will be massive defects and contamination that it will look different and will not. That is the real fact about wormhole. The product disagree with the theory during the last and only observation/measurement you made. So how to fix this information conflict. Well for one you inspect too late. Its better to take one process step and inspect/measure what happened. If you are making a computer chip you take one step of printing one layer and look/inspect at it. Make sure it agree with your theory. Then you seal it up and print another layer circuit on the wafer. Again you need to inspect this second layer before you move on to another processing step. What you doing is oscillating between black holes and wormhole. You making sure that the information in the 4D matches the 10D. If not you must take actions to correct it. What is it that you are correcting? You are correcting the microstates of the black holes. This is tuning and putting boundary on the actions of the microstates. This also known as fine tuning the neural networks. Anyway if the computer actions can be short and follow by a measurement/observation step by step you recover most of the information lost to the 2nd Law of Thermodynamic. You see this fact as live actions. But if you leave the computer actions too long or having too many steps causing a great wear and tear to the switching actions the product comes out nothing but dust and dirt. A total lost of information.
Check out these guys trying to make a self driving car. A human driver respond time between sensory perception of vision on the environment and the computed actions is about 200ms. If the computed actions is longer than 100ms the driver may be in danger of crashing. Too much blind/computing actions and simulation without looking and measuring the changing environment. Anyway check this video.. Workshop on autonomous driving at cvpr'21 youtube.
At 55:30 where there are two competing saddles. These look like synapse of a biological cell. Two black holes have a gap. This means the nervous system is making a computational actions such as thinking and actuating hands or feet. Let say these actions start at microtubules A-lattice or the top black hole. These can be thought as interconnecting logic switches going from the brain to the hand and fingers. Where the finger tip is call a tool tip. If a person hold a pencil the pencil tip is called a secondary tool tip. If a person push a start button of printer or a cnc machine the tool tip is the printer head/tip. And the paper is call the boundary. The boundary is where the tool tip meet to create a copy of what the human computer want to print. This a deterministic, computational, actions following the Schrodinger's equation. Now we need a measurement part of Quantum physic which is the sensory feed back from the tool tip and boundary area back to the finger , hand, and brain. In this sensory feedback/the measurement. The interconnecting parts are called sensors instead of logic switches. The sensory feedback last part would be the bottom black hole which is the opposing synapse made of the B-Lattice microtubules. So let say you are Alice and you what to write ALICE on a paper/boundary. Here since you are in a computer actions mode you will not able to see, smell, taste, hear, or feel what going on the surface of the outside world. For example if the tool tip broke in mid way while you are writing your name you may think you are writing ALICE but the actual is ALI . This paradox in information make all computable actions loose information. It is ignorance to the outside world. This show as two superposition black hole. This is also an open system. Now we can recover all information in the measurement part of Quantum physic or the sensory feedback. This is where synapse fire up making the two blacks holes entangled or transform into a wormhole. This is a close system in which all microstates of what used to be in the black hole to smash into the center of the wormhole. Here microstates are recorded versions of the name ALICE. So the biological cell has to switch rapidly from computed actions mode to sensory perceptions modes wise versa in order to see and do things live. Live as in live streaming.
The changes in the self efficacy graphs were pretty amazing. As an armchair physics follower, it is good to see this kind of outreach and effort to bring more people into one of the most intriguing topics in science - physics rocks! I just wish more people knew that. Enjoyed the presentation. Well done.

You can also adjust for pressure when printing.
If so you may be able to print test layers for study.
The pattern looks like a 3 or 4 color process in printing.
Could you possibly use an offset printing method to seperate layers on a great scale?
