“It is well known that the best way to prevent catching a cold is to stay in shape.” write Mariam Amankerdievna Sidikova Medical, Practice and Nursing JournalLest parents overdo it, she warns that only healthy children “can get stronger with hydrotherapy.”
While exercising may be your best bet, it’s not your only cold prevention strategy. Aman Keldievna, a researcher at Samarkand State Medical University in Uzbekistan, also recommends scrubbing. “Scrubbing should be done year-round,” she says. If done correctly, “scrubbing should begin with the arms, then the legs, chest, abdomen, and back.”
The hardening doesn’t have to be water-based: Amankerdievna also approves of air hardening. “Air hardening is a gentler factor and is allowed for children in any state of health,” she writes.
Sunbathing is another option, but hardening caused by sunlight can be problematic. “Sunbathing is only possible with the doctor’s permission,” says Amankerdievna.
We all know that
If you’re a good speed reader, it’s easy to keep up with all that’s known — just read the thousands of new research papers published every week — but not everyone is good at speed reading.
As a service to slow readers, the feedback aims to summarize some things that are officially well known, as evidenced by the scientific literature (see above), each of which is documented with a sentence beginning with “It is well known that…”
Here are some well-known examples:
Forgetful functors are well known. Cary Malkiewich and Maru Sarazola Writing in a preprint study: “It is well known that stable model structures on a symmetric spectrum cannot be transferred from stable model structures on a continuous spectrum via a forgetting function.”
It’s notoriously complicated. Frank Nielsen wrote in the Journal: entropy, Mentioned One is that “it is well known that the distorted Bhattacharya distance between probability densities of exponential families corresponds to a distorted Jensen divergence induced by a cumulant function between the corresponding natural parameters, and in the limiting case, the two-sided Kullback-Leibler divergence corresponds to the inverse two-sided Bregman divergence.”
Heinz Kohut’s paper on narcissism is well known. write In the journal Psychoanalysis, Self and Contextreminds us that “it is well known that Heinz Kohut’s work on narcissism led to a reevaluation of patients’ healthy self-esteem.”
Ronald Fagin and Joseph Halpern A new approach to belief updatingNote that “it is well known that conditional probability functions are probability functions.”
And Luca Di Luzio, Admir Greggio and Marco Nardeckia write: Physics Review Dassure us “It is well known The giant vector is yearning for ultraviolet (UV) completion.”
How many of these well-known things are known to most people? The answer to that question is unknown. If you know of any well-known things that are less well-known but should be brought to our attention, please submit them (along with documentation) to Well-known things, c/o Feedback.
Fascism Disease
Reader Jennifer Skillen shared in her feedback that thinking about thinking was what sparked her mother-son shared reading sessions, which began several years ago. The Very Hungry Caterpillar And now, embrace New Scientist, It also contains other, more mature content.
“The other day, I started reading the cancer section of “How Do You Think About…?” [New Scientist, 25 May, page 42]And my son said, ‘Mom, why don’t you just read it and replace the word cancer with the word fascist?’ And I did, because I was fine with anything that concerned my son,” Jennifer says.
“To my surprise, the article was still very readable even with the substitutions. It made sense, but was very entertaining. It seems that both cancer cells and fascist cells can respond to changes in their environment and divide rapidly.”
Feedback agrees, and offers some excerpts from the article so readers can judge for themselves: “Cancer cells compete for nutrients and only the fittest survive…Cancer cells have evolved to be the best cancer cells possible, which is usually bad news.”
Jennifer and her son were wondering about other word pair substitutions that readers might have spotted. New Scientist The article states that substitutions “add meaning, increase knowledge, and make things more interesting.”

The question “what’s in it?” has generated many surprises, sometimes involving eels. Rohit Goel and his colleagues from the Pondicherry Medical School in India have uncovered one such surprise.
writing American Journal of Forensic PathologyThe researchers said:Unusual examples “The discovery of an interesting post-mortem remains: the presence of a moray eel among the corpses.”
The research team said that to their knowledge, “this is the first time such a discovery has been reported.”
