Why scientific knowledge changes over time the half life of facts

English
1 answer:
arsen [322]3 years ago
7 0

Answer:

Knowledge, like milk, has an expiry date. That’s the key message behind Samuel Arbesman’s excellent new book The Half-life of Facts: Why Everything We Know Has an Expiration Date.

We’re bombarded with studies that seemingly prove this or that. Caffeine is good for you one day and bad for you the next. What we think we know and understand about the world is constantly changing. Nothing is immune. While big ideas are overturned infrequently, little ideas churn regularly.

As scientific knowledge grows, we end up rethinking old knowledge. Abresman calls this “a churning of knowledge.” But understanding that facts change (and how they change) helps us cope in a world of constant uncertainty. We can never be too sure of what we know.

Answer:

starts looking for work without any hesitation.

Explanation:

In the story "Ted's Champion", Ted was determined to keep the horse though his father decided to sell it. When his mother suggested him that he could find some chores in the neighbourhood so that he earn enough to keep Olly, he immediately starts looking for work without any hesitation.

The lines "Over the next few weeks, Ted visited every local store in search of work. He was willing to do anything to help" remind the readers that Ted was fully determined to work for Olly's sake.

Also when Ted says “But I won’t give him up. No, I won’t do it.”, the readers can understand how much he loved Olly and how strong he was determined to do anything to keep Olly.

“Imputation" means to softly
Ilia_Sergeevich [38]

Words like "bulldozing" and "burned" suggest the following about how Della saved money and how she feels about it:

- When the narrator says Della saved money by "bulldozing" the grocer, he means that she had to insist, almost force him, to reduce prices so that she would not spend all her money.

- When he says her cheeks "burned" with imputation, he means that she feels embarrassed for having to do such a thing. Such an insistence shows how poor she is, and that makes her feel self-conscious.

  • Della is the main character in the short story "The Gift of the Magi," by O. Henry. She and her husband Jim are a poor couple, but they love each other greatly.
  • The passage we are analyzing here shows that Della tried her best to save money. She had to be very insistent with the grocer to be able to save that o<u>ne dollar and eighty-seven cents</u>.
  • She feels embarrassed by it, knowing that when she insists for prices to be reduced she is revealing her own need to be "cheap" due to lack of money.
  • That is what the words "bulldozing" and "burned" mean in the context. "Bulldozing" refers to her forcing the grocer to comply to her means, and "burned" refers to her feeling of embarrassment.
