Connectability by Anna Runkle, 2025

Does it seem like no matter how hard you try to fit in, you don’t feel understood, or like you belong? Like it’s so easy for other people to get together and do ordinary things—but for you it feels so awkward and stressful that you avoid social situations. Or you go through the motions of a connected life, but you never really feel close to anyone, even though you don’t know why.






You’re not alone. An almost universal adult symptom of trauma from childhood is a feeling of disconnection, and it can lead to a lifetime of loneliness, broken relationships, and the feeling that life is passing you by.

Heal trauma-driven disconnection and feel—at last!—like you belong, with guidance from the creator of the Crappy Childhood Fairy healing method and YouTube channel.
Research-backed lessons show anyone suffering from CPTSD and childhood trauma how to form more meaningful, caring relationships.

The Essential Evidence by Avery Love, 2025

This book is a clinically focused reference guide that details some of the most influential medical trials in internal medicine. It is designed for medical students, residents, and early-career clinicians. It helps to bridge the gap between academic literature and bedside decision-making.

link.springer.com/book/10.1007





Each trial is concisely summarized with structured sections that highlight key findings, clinical application, guideline relevance, and how to reference the study during teaching rounds. The goal is to provide a practical, high-yield resource that enhances evidence-based practice and prepares trainees to speak confidently about landmark research. The nine areas of clinical medicine discussed are general internal medicine, cardiology, pulmonology, critical care, endocrinology, nephrology, hematology/oncology, rheumatology, gastroenterology and infectious diseases.

In an era of information overload, The Essential Evidence: The 100 Landmark Trials Every Clinician Should Know solves the problem of accessibility and relevance by curating some of the most practice changing studies, written in a digestible and applicable format.

Diet and Alzheimer's Disease: Let Food be Our Medicine by Jai Malik, 2025

This book addresses all aspects of diet in preventing and managing Alzheimer's disease. It highlights the role of specific dietary components like polyphenols, flavonoids, catechins, lignans etc., along with various dietary patterns in improving neuronal health and mitigating the symptoms of disease.

link.springer.com/book/10.1007




Role of diet and its impact on overall health and well-being have emerged as promising areas of research. The comprehensive and holistic approach offered in the book provides a thorough scientific view of dietary components in preventing, managing or delaying the onset of Alzheimer’s disease (AD). By incorporating the most recent scientific research and evidence-based practices, this book presents the necessary knowledge and tools to improve cognitive health and enhance quality of life through dietary choices. In addition, this book also gives an overview of the latest scientific contributions in the field of the pathophysiology of this disease and how this understanding helps in developing newer therapeutic interventions.
With high-quality images, chemical structures, and well-structured tables, the book aims to present intricate information in an accessible and interesting manner. By incorporating research case studies, the book not only educates but also motivates readers to take tangible steps towards effective dietary management.
Thus this book serves as a crucial guide for utilizing the potential of nutrition in the battle against Alzheimer's disease. It is mainly targeted at nutritionists, post graduate students, researchers and biochemists working in the area of Alzheimer's.

I can say that my GPS “thinks” I took a wrong turn without really committing myself to my GPS being a conscious, thinking being. My GPS has no mind, and thus no mental map of the world, yet I am not wrong in understanding its output as a valid representation of my location and my destination.

Similarly, even though physics leaves no room for the dynamic passage of time, time is effectively dynamic to me as far as my experience of the world is concerned.

The passage of time is inextricably bound up with how humans represent our own experiences. Our picture of the world is inseparable from the conditions under which we, as perceivers and thinkers, experience and understand the world. Any description of reality we come up with will unavoidably be infused with our perspective. The error lies in confusing our perspective on reality with reality itself.

Similarly, my research suggests that the passage of time is neither real nor an illusion: It’s a projection based on how people make sense of the world. I can’t really describe the world without the passage of time any more than I can describe my visual experience of the world without referencing the color of objects.

Time as a psychological projection

One common option has been to suggest that the passage of time is an “illusion” – exactly as Einstein famously described it at one point.

Calling the passage of time “illusory” misleadingly suggests that our belief in the passage of time is a result of misperception, as though it were some sort of optical illusion. But I think it’s more accurate to think of this belief as resulting from misconception.

Change just means that the situation is different at different times. At any moment, I remember certain things. At later moments, I remember more. That’s all there is to the passage of time. This doctrine, widely accepted today among both physicists and philosophers, is known as “eternalism”.

This brings us to a pivotal question: If there is no such thing as the passage of time, why does everyone seem to think that there is?

Under relativity, all times are equally real. Everything that has ever happened or ever will happen is happening now for a hypothetical observer. There are no events that are either merely potential or a mere memory. There is no single, absolute, universal present, and thus there is no flow of time as events supposedly “become” present.

How much time elapses between events, and what time something happens, depends on the observer’s frame of reference. Observers moving relative to each other will, at any given moment, disagree on what events are happening now; events that are happening now according to one observer’s reckoning at any given moment will lie in the future for another observer, and so on.

This notion affects our understanding of what clocks actually do. Because the speed of light is a constant, two observers moving relative to each other will assign different times to different events.

In a famous example, two equidistant lightning strikes occur simultaneously for an observer at a train station who can see both at once. An observer on the train, moving toward one lightning strike and away from the other, will assign different times to the strikes.

Someone floating in space sees a spaceship going by to the right. But the universe itself is completely neutral on whether the observer is at rest and the ship is moving to the right, or if the ship is at rest with the observer moving to the left.

To take this fact seriously, he argued, is to take all object velocities to be relative.
Nothing is ever really at rest or really in motion; it all depends on your “frame of reference.” A frame of reference determines the spatial and temporal coordinates a given observer will assign to objects and events, on the assumption that he or she is at rest relative to everything else.

이거저거 곁가지들 다 쳐내고 LLM의 프로그래머 대체에 대해서만 이야기해보자면, LLM 기반 툴들은 디테일로 들어가면 약해지는 부분이 있어서 그런 부분은 사람이 잡아야 하니 아직까진 “완전 대체”는 불가능하다는게 내 평가임. 다만 사람이 하는 반복작업을 줄여주는 측면이 있어서 일자리 자체가 줄어드는 상황은 실제 발생하고 있음. 이후 AGI가 실제로 만들어지더라도 (물론 더 큰 폭으로 대체가 되겠지만) 이때도 프로젝트를 고민할 수 있는 시니어는 필요할거라고 생각함. 결국 책임을 질 누군가는 항상 필요할거라고 본다.

Then, Albert Einstein came along.

In 1905 and 1915, Einstein proposed his special and general theories of relativity, respectively. These theories validated all those long-running suspicions about the very concept of time and change.

Relativity rejects Newton’s notion about time as a universal physical phenomenon.

By Einstein’s era, researchers had shown that the speed of light is a constant, regardless of the velocity of the source.
