The Scientific Method Produces General Principles by Whic...
Just as the first means by which science reduces the danger of error is the continual comparison of ideas and concepts, the second is the formulation of general principles by means of which we can understand cause-and-effect or sequential relationships among events. The function of a general principle or scientific law is twofold; to organize discrete objects and events in systematic order so that we can deal with them more effectively and exercise greater control over them; and to provide a ...10 OCT 2025 by ideonexus
Observation Provides Data on Problems, but Cannot Solve Them
A good illustration of the scientific method, in which observations are made for the purpose of identifying difficulties and analyzing situations, is the procedure followed by a physician when he makes a diagnosis. A doctor does not write a prescription solely on the basis of what his patient tells him; he uses instruments to take the patient’s temperature to examine his feces, and to analyze his urine. It is only after he has made these examinations that he writes his prescription; without...05 MAR 2025 by ideonexus
A Brief Primer on TEE, BMR, RMR, and the Thermic Effect o...
When discussing human metabolism, four concepts often arise: total daily energy expenditure (TEE), basal metabolic rate (BMR), resting metabolic rate (RMR), and the thermic effect of food (TEF). Energy expenditure science can feel alphabet-soup–heavy, so let’s clarify these key terms in more depth:
Total Daily Energy Expenditure (TEE): TEE is the total energy (calories) you burn in 24 hours. It encompasses every energy-demanding process in your body—from keeping your heart pumping to...08 DEC 2024 by ideonexus
How Steroids Produce Rage in Users
I pride myself on never losing my cool I've never screamed at anyone I've never gotten physical with anyone but the ideas in my head that tell me to do things tell me to do unspeakable things like what they're unspeakable I'd have to speak them you really want to know Mum I'm also [ __ ] weird so just remember that no we bit most people uhprobably don't have this severity but I'll read a comment on social media directed at me I guess about me um and it's from like you know nameless faceless ...22 OCT 2024 by ideonexus
Exercise Creates Structural Stress
Now, the other kind of stress Structural stress from activity that physical activity cause is structural stress. Now, when I was running this morning, for example, my mitochondria were generating all kinds of ATP to fuel my body, but my mitochondria were also spewing out all kinds of reactive oxygen species, which cause widespread damage throughout my body. I was getting mutations in my DNA, those that damage is causing my telomeres at the end of my chromosomes to shorten its damaging cells. ...22 OCT 2024 by ideonexus
Why Humans Evolved to be Active
Humans of all to be much more physically active than our ape ancestors. Typical chimpanzee walks maybe two to three kilometers a day, and they take maybe what, three, 4,000 steps a day. A typical hunter-gatherer takes about 15 to 20,000 steps a day. Per kilo hunter-gatherers spend about twice as much energy per kilo on being physically active per day than our ape cousins. And importantly, that physical activity occurs as we age, right?
So Americans are pretty inactive, as we all know. A typ...01 OCT 2022 by ideonexus
Diaphragm Exercises Reduce Blood Pressure
"The muscles we use to breathe atrophy, just like the rest of our muscles tend to do as we get older," explains researcher Daniel Craighead, an integrative physiologist at the University of Colorado Boulder. To test what happens when these muscles are given a good workout, he and his colleagues recruited healthy volunteers ages 18 to 82 to try a daily five-minute technique using a resistance-breathing training device called PowerBreathe. The hand-held machine — one of several on the market ...31 OCT 2018 by ideonexus
