Dark Energy
So, from a Newtonian perspective, dark energy is a wild goose.

From a Newtonian perspective yes. Kindly go through the thread, it's short.

Could we be on a wild goose chase?

Direct Proportionality
I would like an intuitive explanation also please, if possible. I've noticed the word "independent" appears in almost all answers to this question. What does it mean exactly and how does [math]F \propto m[/math] independent of mass and [math]F \propto a[/math] independent of acceleration lead to the conclusion that [math]F \propto ma[/math]

Direct Proportionality
Can you explain a little bit more about how the constants being independent of acceleration and mass matter to understanding this rule that if ... [math]n \propto q ~ \& ~ n \propto r, then ~ n \propto qr[/math]

Thanks a million. I got most of what you said except the part quoted above.

Dark Energy
Okay Work = Fd F = ma Work = mad The expansion is acclerating, but there's no mass i.e. Work = 0 × a × d = 0 joules.

Dark Energy
From what I know, dark energy is the posited energy driving cosmic expansion. This seems to imply cosmic expansion is work (requiring energy), but then I was told cosmic expansion is the space stretching and space has no mass. How is work being done in cosmic expansion when no mass in involved, a work that requires dark energy?

Last I checked, they reproduce by budding.- Microbiology
Heat denatures proteins i.e. it disrupts their structure which as you know means proteins lose their function. HSP's, probably by binding to proteins, make them, in a sense, heat-resistant. Que sais-je?- Genetic Problem
DD & dd OR Dd & dd 1. DD & dd: Dd or Dd or Dd or Dd (all Rh+) OR 2. Dd & dd: Dd or Dd or dd or dd (2 Rh-) P(Rh-): 2/8 = 1/4 = 25%- Psychology is a soft science (split from Childhood hyperactivity; what makes it a bad thing?)
We'd have to first work out what mental illnesses are. Then see if fear fulfills any criteria for a particular psychiatric malady. Diagnosing physical illnesses is much easier and more precise than mental ones.- Psychology is a soft science (split from Childhood hyperactivity; what makes it a bad thing?)
I have some idea how schizophrenia was/is diagnosed. Look for cardinal symptoms like, as per Eugene Bleuler, autism, ambivalence, inappropriate affect, loosening of association. How exactly these are determined to be present in a suspected schizophrenic is an unknown to me. Indeed!- Psychology is a soft science (split from Childhood hyperactivity; what makes it a bad thing?)
Interesting. Pathophysiological description of mental illnesses consist of many claims that could be, in principle, rephrased so to speak in terms familiar to a doctor/nurse. This however hasn't happened.- Suicide Prevention
I know what the OP means by suicide prevention - taking one's own life is a (mental) illness.- Gilles de la Tourette Syndrome
That's news to me! Gracias. Any ideas as to what actually happens to the brain in coprolalia?- Psychology is a soft science (split from Childhood hyperactivity; what makes it a bad thing?)
🙂 Spoken like a true psychologist. In me haste I failed to recognize the complexity of the subject and give due credit to the dedication and brilliant work of psychologists the world over. Gracias. I'm not as up-to-date with psychological techniques as I'd like to be. I'm sure there are well-tested methods in use in the diagnosis & management of mental illnesses. Do you know of any, other than psychometrics? An excellent observation. It'll be interesting to watch how neuroscience will get along with psychology.- Psychology is a soft science (split from Childhood hyperactivity; what makes it a bad thing?)
I only wrote what I read but what I read could've been biased. So yeah. The issue, to the extent I can tell, is the greater degree of subjectivity involved in psychology as compared to the other subfields of medicine. For instance there's no lab value from (say) a blood test that could zero in on an ADHD patient. That said, I must confess my ignorance of the accuracy and reliability scores of the staple of psychology, to wit psychometrics.- Psychology is a soft science (split from Childhood hyperactivity; what makes it a bad thing?)
Interesting take ... ADHD is classified as a disability last I heard. There are so many ways it can disrupt an afflicted person's life that it's not surprising at all that psychologists have given it some much attention. Gracias for the link.- Psychology is a soft science (split from Childhood hyperactivity; what makes it a bad thing?)
Psychology is, at the end of the day, a soft science, a very, very soft science. Some say much of its findings can't be replicated which is a serious setback to any field wanting to claim the IS A SCIENCE badge. If I'm way off the mark, please someone do kindly educate me!- Temperature conversion
You can use your cell phone's calculator - mine has a temperature conversion function/feature.- Precision - The Magic Bullet
Interesting! Gracias. This is also interesting! Merci. Antibodies, are they the most specific antmicrobials in the body's arsenal? Arigato. Vaccines, last I checked, work their magic via antibodies . To All The body's natural defenses are what we should be working on but that's not to say if a magic bullet can be found we shouldn't use it, oui mes amies? Before I forget, thanks to all contributors.- Hair Loss
Gracias. Male-pattern baldness?- Are we different in the physical sense?
