How do you get rid of radioactive waste?

Radioactive waste disposal involves finding a safe place to store it until it’s no longer radioactive. Different types of waste give different levels of radiation. Radioactive waste disposal is divided into three general categories: low level, intermediate level, and high-level waste. Low-level waste typically has short-lived radioactivity. It does not require cooling nor shielding to handle. An example of this would be a lab coat that has been contaminated by radioactive material. It is disposed of through shallow land burial.
Intermediate-level waste requires shielding to handle but not cooling. An example of this would be metal fuel cladding at a nuclear power plant. This type of waste is stored at a nuclear waste repository. Please note that the United States does not define this category, but other countries do. High-level waste requires both shielding and cooling to handle.  Used nuclear fuel is an example of this. High-level waste is stored in a deep geological repository.
There are other waste categories, but this should be enough to get you started. See the links below for further research.

How does Bilbo show leadership and courage in The Hobbit?

Bilbo’s increase in confidence and courage is the defining aspect of his character arc. At the beginning of the novel, he is shut away content in his Hobbit hole, happy to remain separate and coddled from the rest of the world. In the movie, Bilbo chooses to join the dwarves on their quest out of a sense for adventure. In the book, however, Bilbo wants nothing to do with them and only joins because he had been duped into signing a contract. Despite being on the adventure somewhat against his will, Bilbo still proves himself time and again, saving the dwarves from the spiders, the trolls, and a number of other dangers they encounter along the way. Bilbo’s character arc has even been cited as a sort of Christian metaphor for the growth of the soul, though how much Tolkien intended on this front is up for debate. From a thematic standpoint, the ring of invisibility also plays into Bilbo’s brand of bravery. If Hobbits are the overlooked creatures of Middle Earth, then it is noteworthy that...

In “Goodbye to All That,” Joan Didion writes that the “lesson” of her story is that “it is distinctly possible to remain too long at the fair.” What does she mean? How does the final section of the essay portray how she came to this understanding, her feelings about it, and the consequences of it?

In this classic essay, Didion describes moving to New York City from her native Sacramento at the age of twenty-one, and, as she freely admits, a somewhat naive twenty-one, her mind, "programmed by all the movies I had ever seen and all the songs I had ever heard about New York," with the typical feeling, at that age, that, "nothing like this...has ever happened to anyone before." Intending to stay for only six months, she falls in love with the city. As she says, "I do not mean 'love' in any colloquial way, I mean that I was in love with the city the way you love the first person who ever touches you and never love anyone quite that way again." This initial love led her to prolong her residency, since, "I still believed in possibilities then, still had the sense, so peculiar to New York, that something extraordinary would happen any minute, any day, any month." But as the next years roll past, and the "new faces" she encounters...

Why does the poet say "all the men and women merely players"?

It's one of the most famous lines in literature: All the world's a stage,And all the men and women merely players . . . This famous saying comes from Shakespeare's play As You Like It, and it's spoken by Jacques. What he's saying here is that simply going about our daily lives is a type of performance. Just like actors on a stage, we all have roles to perform: Daughter. Student. Sister. Captain of the soccer team. The fact that Shakespeare writes that men and women are merely players suggests that the roles are preordained and that a person's choice in being a mother, for example, or a doctor or starting point guard for the Brooklyn Nets is out of their hands. What roles a person performs over the course of their lifetime is up to fate. The notion that "all the world's a stage" has entered pop culture, but within the context of the play, this idea does not sit well with Jacques. He's a pessimist, and the idea that everything is up to fate makes...
