We've been told that angular magnification is defined as the ratio of the angle subtended by the image to the angle subtended by the object. But why would we need a quantity called angular magnification? Won't the simple magnification formula do?

I was discussing this with a colleague at work, and we couldn't find any definitive answers. Are, for example, the joints in Wolverine still regular ones, or are they covered in adamantium as well? And what about his cartilage?. In short, what are the ears of Wolverine made of?

As you can see in this article on Wikipedia, there is a distinction made between notes, citations and references. I would like to have a section called citations at the end of my document which I can refer to like this[2]. [2] Lasker (1934), p. 73. which is to be found in my references under

I saw that video a few time ago. It shows the story of Brutus the Grizzly which is living as a pet with his owner. I take grizzlies as dangerous animals and so I think the grizzly must have been castrated, had his fangs and claws removed ( and so this makes the whole thing

I ordered 3 V CR2 batteries. Actually they are 2.92 V and 2.93 V. Should I consider them faulty, or is this difference from the nominal voltage acceptable?

I usually say "I'm gonna ride the bus". But why is it "the" instead of "a" or nothing. Sometimes a noun doesn't need "the" or "a". Like some people say "call transportation" or "goto school". Transportation and school are both nouns but why don't they need anything before these words?. How do you determine when

I'm trying to prove that matrix multiplication is associative, but seem to be making mistakes in each of my past write-ups, so hopefully someone can check over my work. Theorem. Let $A$ be $\alpha \times \beta$, $B$ be $\beta \times \gamma$, and $C$ be $\gamma \times \delta$. Prove that $(AB)C = A(BC)$. Proof. Define general

Here's an instance of a $2$x$3$ sliding puzzle:. The $2$x$3$ sliding puzzle is just a smaller version of the well-known 15 puzzle. Many guides exist on solving the 15 puzzle, and there are strategies that work on any $n$ x $m$ puzzle, where $n \ge 3$ and $m \ge 3$, such as the one in

I want to refactor the following code because I don't feel comfortable about using assignment inside comparison operator. It looks like pretty idiomatic C, but do you think this is a good practice in Java?. Here is an alternative. UPDATE: I've stumbled across a similar question asked couple years ago. It seems that opinions on

The TI MSP430F20XX series has a 12-bit internal ADC output, which is right-justified. What is the difference between a left-justified output and a right-justified output? What are their pros and cons?

Is there a limit for how many gifts you can collect from pokestops? I have over 100 friends and it seems like there is a limit how many gifts I can collect from pokestops. For the last 100 pokestops I have not received any gifts?. Im not talking about the limit on 10 gifts in your

I can't seem to have my material turn transparent in blender 2.80. Heres some screenshots, is there something I'm missing?. This is how it looks in EEVEE:. Here is my node setup:

If a function is a combination of other functions whose derivatives are known via composition, addition, etc., the derivative can be calculated using the chain rule and the like. But even the product of integrals can't be expressed in general in terms of the integral of the products, and forget about composition! Why is this?

The service manual says:. "Perform the final tightening of the rear suspension member and axle installation position (rubber bushing) under unladen condition with tires on level ground". Does this just mean to remove the jack and tighten the nuts to spec torque with nothing significant in the back seat/deck etc? i.e. full weight of the vehicle

Book 3: Change is all about Korra having to deal with issues and conflicts without the help from her past lives. She feels alone, and that there is no one that truly understands her. This is shown, especially in The Ultimatum and A Breath of Fresh Air, where Korra is seen trying to contact Aang

Built in the early 1910s, Japan's Kongo class battlecruisers had eight 14-inch guns, a speed of about 30 knots, and a displacement of about 26,000 tons. This gave them advantages over British contemporaries such as the Orion class battleships (ten 13.5-inch guns, 21 knots and 22,000 tons displacement), but perhaps less so compared to the

What are the differences among the words mentioned above? To me "yell at" and "nag at" are informal way to say that someone disapproves something to someone else, with the difference that "yell at" involves the action of actually "yelling" while the other one doesn't necessarily. "Scold" as far as I've understood means the same thing

I'd like to purchase a Shadow weapon from a merchant and while I have the couple of rare components needed, I am short a lot of metal shards. While I could go out and hunt random beasts for their metal shards, I was wondering if there's a particularly good place to do so

Yeah, just that. Has Yoda ever turned to the dark side of the Force? Has he ever been tempted? Even just for a moment? Even just in his mind?

I just found a 4 strength, 4 speed, 5 stamina horse. an upgrade from my speed 3 horse. I can’t believe how much faster this horse is. Now I want to find a horse with speed 5. Where can I find one?
