Students have their phones and screens. The teachers and admin rationalize their failure to teach basic arithmetic because they’re also so innumerate they can’t reckon the opportunities that are lost when students lack automaticity in basic computation. The schools are kneecapping the kids financially, let alone in terms of STEM careers. Thank God for @sharemath and his series. youteachyou.org/?srsltid=Afm…

You nailed the physiology perfectly. The intrinsic automaticity of the SA node is a literal built-in survival mechanism. It is fascinating that the heart acts as an independent contractor as long as it gets its oxygen. Do you see a lot of interesting cardiac cases in your daily nursing practice?

B) Heart ❤️ The heart has its own electrical system - the Sinoatrial (SA) node - which generates impulses intrinsically, without any input from the brain. This is why:- In brain death, the heart can still beat We need cardiorespiratory criteria brain criteria separately A brain-dead patient is NOT the same as cardiac death This is also why heart transplants work - the donor heart keeps beating in a new body with zero brain connection. This is called cardiac automaticity and it's why brain death declaration requires an apnea test absent brainstem reflexes, not just a flatline ECG.

🇨🇳 KINDERGARTEN CODERS: China's AI Arms Race Starts at Age 4 In a Shenzhen preschool, 4-year-olds are issuing voice commands to an AI robot called Doubao, identifying patterns and playing machine-learning games. They're not just digital natives — they're AI natives. 📚 Beijing pilot programs roll out this year: minimum 8 hours of AI instruction per academic year for primary & secondary students, scaling up over time. Education Minister Huai Jinpeng calls AI the "golden key" to China's transformation. A national white paper will lock in the framework — target: global AI leadership by 2030 (per the 2017 "New Generation AI Development Plan"). 🇺🇸 Meanwhile in the US: a 2023 Pew survey found only 6% of public school teachers believe AI does more good than harm in classrooms. ~25% say more harm than good. Many districts ban it outright. No national AI curriculum exists. 🌍 Others moving fast: • 🇰🇷 South Korea — AI across grade levels • 🇸🇬 Singapore — mass teacher training AI learning platforms • 🇫🇮 Finland — free national AI courses for all citizens 🧠 Why early matters: researchers compare AI fluency to language acquisition — start at 4, develop intuitive "automaticity." Start at 30, you'll always have an accent. "It's jazz, not classical," says one educational technologist. "AI fluency is improvisational, intuitive, cognitive." ⚠️ The warning from NYC's Liz Ngonzi (International Social Impact Institute): "This isn't just a digital divide — it's a digital chasm. Every month a student isn't on board, they fall a year behind." If AI is the new literacy and the foundation of the Fourth Industrial Revolution, the future may be written by those who learned it first. 📖 Source: eSchool News / Mitzi Perdue (Institute of World Politics & American Society for AI) #AI #ArtificialIntelligence #Education #AILiteracy #China #Shenzhen #Beijing #Doubao #EdTech #K12 #Kindergarten #FutureOfWork #FourthIndustrialRevolution #AIArmsRace #USChina #TechPolicy #STEM #ChatGPT #Schools #Teachers #Curriculum #SouthKorea #Singapore #Finland

Here is an AI answer that I massaged in order to make a point about rote - the primary reason for the decline: the "Enjoyment" Trap: The insistence that kids need to "enjoy learning" at every step has led to curricula that prioritize engagement activities over the rigorous, repetitive practice required for mastery. While engagement is valuable, academics often mistake entertainment for learning. Ignoring the Foundation: By rejecting rote learning entirely, schools often skip the automaticity phase. Just as a musician cannot improvise without scales, a student cannot solve complex algebra if they are still counting on their fingers, nor can they comprehend a text if they are still laboriously decoding every word. Evidence of Failure: Recent analyses show that states and districts that have returned to phonics-based instruction (which relies heavily on rote decoding practice) and explicit math drills are seeing improvements, while those sticking to purely "conceptual" or "inquiry-based" methods continue to struggle

C) Heart The heart has its own built-in electrical system. Specialized pacemaker cells in the SA node generate spontaneous impulses even without signals from the brain. That’s why a heart can continue beating for a short time after being removed from the body, as long as it still has enough oxygen and energy stores. Fun fact: This property is called automaticity—one of the most fascinating features of human physiology. 🫀⚡

C) Heart The heart has its own built-in electrical pacemaker system (especially the SA node). These cells can generate spontaneous impulses automatically called automaticity. So even outside the body, if oxygen and nutrients are supplied, the heart can continue beating on its own for some time.

The intrinsic automaticity of the SA node is a true marvel of human physiology. Since you brought up ex vivo preservation, I have a follow-up question for you: What is your take on the newer heart-in-a-box (warm perfusion) technology versus traditional cold storage for extending that time limit?

Answer: C) Heart The heart can continue to beat for a period of time even after being completely removed from the body, provided it still has an adequate oxygen and energy supply. Why is this possible? The heart possesses intrinsic automaticity due to specialized pacemaker cells in the sinoatrial (SA) node. These cells spontaneously generate electrical impulses without requiring input from the brain or spinal cord.

C. Heart The heart has its own intrinsic electrical conduction system, especially the SA node, which can generate impulses without input from the brain or spinal cord. In the right conditions (adequate oxygen and nutrients), an isolated heart can continue beating for a period of time outside the body. This property is called automaticity.

The heart is a total rebel—literally born to beat solo!❤️ Its sinoatrial (SA) node is like a built-in drummer that fires electrical impulses on its own (automaticity), around 60-100 times per minute, no brain required. That's why a removed heart can keep pumping for a while if it gets oxygen, nutrients, and the right temp/electrolytes. Modern beating-heart transplants even keep donor hearts actively beating in a special portable box during transport- way better than old-school ice preservation. Nature engineered the ultimate independent contractor. Mind officially blown. What's your favorite "body hack" fact?

Does this make the automaticity win? Or is there going to be a game 5?

How humbly curious are you about new research suggesting the brain’s ability to #multitask? • Note if @X algorithms “know” about the depth of your level of #curiosity and bring to your attention this post. • Note if you’ll patiently read this post’s preamble and/or click the link. • Note your thinkably thinkable thinkings, #thoughtings, and thoughts about #multitasking—your willlingess to metacognitively engage in multithinking thinkingness, #thoughtingness, and #thoughtness. Published abstract curated by @EnclaveAcademy into “sight-sized” sentences—to function as microlearning metacognition ignition keys: “Object category learning is a foundational cognitive process. Most human category learning studies involve brief paradigms lasting a few hours and show increased shape tuning in visual areas and task-dependent responses in pFC. Other studies also identify a ‘frontal bottleneck’ that limits multitasking. However, real-world categorization often involves months or years of practice, potentially producing qualitative shifts toward automaticity. We tested the hypothesis that extensive training causes a spatio-temporal shift in the neural circuitry supporting categorization. Participants were trained over >30,000 trials across 5–10 weeks to categorize novel morphed car stimuli via a mobile app. We used fMRI and EEG rapid adaptation techniques to examine neural responses after initial learning (∼4 hr in 1–2 weeks) and after extensive training (∼16 additional hours over another 4–8 weeks). Converging fMRI and EEG results showed that extensive training fundamentally remodeled task-related circuitry: Visual areas in ventral occipito-temporal cortex (vOTC) were initially shape-selective, but category-selective responses emerged in the vOTC after extensive training. The vOTC also showed decreased functional connectivity with the pFC and increased connectivity with motor output areas. This supports the hypothesis that extensive experience enables category decisions to occur outside of the ‘frontal bottleneck.’ Critically, the decrease in connectivity between vOTC and pFC was associated with improved categorization performance while dual-tasking, indicating increased automaticity. These findings demonstrate that prolonged training reshapes the neural basis of categorization, shifting it from a flexible but attentionally controlled process to a more streamlined, automatic process.” —@mitpress #ThinkToThink™ with “MIT metacognition,” as we at @enclave_center strategically refer to layers of particularly industrious rigorous “thinking about thinking”—for higher-order thorough thinking (HOTT). @MIT continually illustrates for the world ways higher-order thinking (HOT) isn’t HOTT enough.

Backtests are blind. And randomly picked from periods I never trained on. This is also my 6 iteration. Ones I taken online before averaged about 15-20% a month. The goal has been to consistently clear 100% a quarter which I could achieve semi-automaticity. So the mission has been to close the loop.

📆 Weekly author's column; ⚡️ Head of the project "Tactical Medicine Courses" with the call sign "Latyshev"; ✅ Specially for the channel 1465 MSP | 4 OMSBr The tactics of a medic in urban combat are radically different from those in field medicine and require a unique set of skills, combining military training and medical expertise. The urban environment, with its limited space, cramped quarters, and numerous shelters and threats from different levels of height, is the most challenging theater of military operations for providing aid to the wounded. Every step of a medic in this environment is part of a tactical decision, and speed and safety determine the chances of survival not only for the patient but also for the entire assault team. The fundamental principle is to constantly follow the algorithm "fire, maneuver, medicine". At the moment of direct contact with the enemy, a medic is primarily a fighter. His primary task is to support the team in suppressing or eliminating the threat with his fire. Attempting to provide aid under targeted fire will only lead to new losses. Only after the area has become relatively safe or the wounded can be dragged to a shelter, does the medic switch to his direct function. His movement should always be coordinated with the rest of the team, who provide him with cover and fire support. The choice of shelter and position for work is critically important. In urban conditions, walls, building corners, destroyed structures, and even vehicles become temporary aid stations. A medic must assess the shelter not only from the point of protection against bullets and shrapnel, but also from the perspective of rapid evacuation and the availability of escape routes. Work is carried out in a crouched position or on one's knees to minimize the profile. The medical kit should be unpacked and organized in such a way that all necessary items - tourniquets, bandages, decompression needles - are accessible with one hand in seconds. The aid protocol is adapted to the realities of combat and follows the TCCC principle, where the priority is to stop catastrophic bleeding. The examination of the wounded is carried out according to the MARCH scheme, starting with the search for massive bleeding, which is the main cause of preventable losses. The application of a tourniquet takes priority over all other procedures. This is followed by an assessment of the patency of the airways, signs of a tension pneumothorax, which requires immediate decompression, and only after that - infusion therapy and the fight against hypothermia. All actions should be brought to automaticity in order to be carried out in conditions of stress, poor lighting, and chaos. The evacuation of the wounded is the culmination of the medic's work and requires the coordination of the entire team. Various techniques are used - from quickly pulling out with equipment to organizing stretchers. Constant communication with the team commander is vital to determine the moment when evacuation is possible without risk to the rest. Thus, a medic in urban combat is not a passive paramedic, but a highly mobile and aggressive fighter, whose work in saving lives is an integral part of the overall tactical success of the unit.

Right on. Did it live up to the claim of automaticity in math?

Noiceeee I’m 85% and for some reason my phone automaticity downloaded the update and debating on if should install it or wait
