Dave Plummer, a retired Microsoft engineer, explains why Microsoft decided to offer Windows 10 as a free upgrade and the implications of this decision. He dives into the challenges Microsoft faced with Windows 8, the decline of the PC market, the influence of competitors like Apple and Linux, and the shift towards treating Windows as a service rather than a standalone product. The move a

Stock prices reflect investors’ expectations about the future earnings and risk of the companies they invest in. When expectations or risk change, due to something like nonsensical sweeping tariffs, stock prices can change, and they can change quickly and dramatically.

Falling stock prices do not mean that the market is broken or that the world is ending; they are expected from time to time, and their inevitability should be built into every investment plan.

Market Crashes (2025 Edition)

Ben Felix discusses the nature of market crashes, emphasizing that they are a normal part of investing and should be anticipated by investors. He explains the historical resilience of stock markets, the impact of emotional narratives during downturns, and encourages investors to review their risk tolerance and financial plans.

Key Points

Market Crashes are Normal

Market crashes, while unsettling, are a typical part of investing, reflecting changes in expectations

Thanks to Galilean relativity it should be just as hard to run on an inclined treadmill as it is to run on a hill of the same incline. But you don't gain gravitational potential energy on a treadmill, so can it really be true?

:::spoiler summerizer Steve Mould explores whether running on an incline treadmill is as taxing as running up an actual hill of the same incline. Through reasoning and experiments, he investigates the energy expenditure involved in both activities, ultimately discovering that while the treadmill might initially seem easier, empirical results show that running uphill on a ramp requires slightly more energy than on a treadmill, accounting for various factors including air resistance and friction.

Key Points

Theoretical Considerations

Steve discusses the theory behind the energy expenditure of running on an incline treadmill versus running up a hill, questioning whether the lack of vertical lifting on the treadmill reduces the difficulty.

Bill explains how the two-liter plastic soda bottle begins as a plastic tube, called a preform, which is heated and inflated with air in a bottle-shaped mold. He explains how the stretching of the preform creates a crystalline regions in the bottle's plastic (polyethylene terephthalate) that create a bottle with great strength, low permeability to carbon dioxide, but which is also lightweight—some 35 times lighter than a glass bottle of the same size. Bill explains key features of the bottles design, including: why the bottle looks like it does, why the neck has gaps in its threads, and how the tamper-proof ring works. He also discusses "hot-fill bottles" used for sports drinks and plastic juice bottles, noting the panels molded into the bottles to accommodate temperature changes. Lastly, he discusses briefly the recycling of PET bottles, although noting that about 75% of the 500 billion PET bottles manufactured annually end up in landfills or are incinerated.

In this video, Professor Bart Kay discusses the heart's function with Dr. Stephen Hussey, exploring unconventional theories about the heart's role in blood circulation. They examine the heart's efficiency as a pump and propose that it operates more like a vortexing hydraulic ram rather than a traditional pressure propulsion pump. They also discuss the concept of 'structured water' and its implications for heart health and circulation, challenging standard views on heart disease and treatment.

Key Points

Heart as a Pump

Dr. Hussey questions the traditional view of the heart as a pressure propulsion pump. Instead, he suggests it functions more like a vortexing hydraulic ram, challenging classical cardiac physiology.

Efficiency of the Heart

Current understanding suggests the heart may be only about 30% efficient as a pump. Historical experiments and recent studies indicate that blood can flow without the heart actively pumping, particularly in embryos.

Nutrition Epidemiology is a branch of pseudoscience. In this discussion, Prof Kay provides 7 major flaws (each of which are sufficient on their own) to invalidate and discredit nutrition epidemiology and nutrition epidemiologists as fantasists, pseudoscientists, and crackpots. These pseudoscientists have abandoned scientific discipline, and instead indulge in criminal propaganda. Check it out! Don't forget to subscribe, and hit the bell icon. Also leave me your thoughts.

Summarizer:

In this video, Professor Bart Kay argues that nutrition epidemiology is flawed and misleading due to seven main invalidating issues. He emphasizes that association does not imply causality, discusses problems with observational studies, and highlights biases in data collection and reporting that result in false conclusions about health outcomes related to nutrition.

Key Points

Association vs Causation

Professor Kay stresses that simply having an association between two variables does not prove

Dr. Ford Brewer discusses a simple at-home test involving grip strength that can help predict longevity and overall health. He emphasizes that grip strength is related to metabolic health, cardiovascular disease, and cognitive function. The video also explains the impact of aging on muscle development and recommendations for improving grip strength, alongside discussing the importance of strength training for longevity.

Key Points

Grip Strength as a Longevity Indicator

Grip strength is a reliable measure of overall muscle strength and health. Studies show that better grip strength correlates with a 31% reduction in all-cause mortality, which makes it a significant health indicator beyond traditional metrics like glucose levels.

Impact of Aging on Muscle Strength

As individuals age, it becomes harder to build and maintain muscle mass. Older adults need to exert more effort and time into strength training to achieve results, but it is still feasible to impr

In the comments he said he was sick with the flu, it looks more serious then that.

The dramatic weight loss, the loss of fat around the face, the skin color, and the hand bandage.

I've really enjoyed his content, fallen asleep to his videos. I hope he is ok and will recover quickly, but the dramatic change has me speculating something more serious then the flu.
