Suppose that the probability that a passenger will miss a flight is .0982. Airlines do not like flights with empty seats, but it is also not desirable to have overbooked flights because passengers must be "bumped" from the flight. Suppose that an airplane has a seating capacity of 55 passengers. (a) If 57 tickets are sold, what is the probability that 56 or 57 passengers show up for the flight resulting in an overbooked flight? (b) Suppose that 61 tickets are sold. What is the probability that a passenger will have to be "bumped"? (c) For a plane with seating capacity of 240 passengers, what is the largest number of tickets that can be sold to keep the probability of a passenger being "bumped" below 1%?

I apologize for the misunderstanding. Here is a summary of our previous conversation based on your first post: 1. You asked what “wtf is this we talked about?” referred to. 2. I responded by providing a summary of the previous conversation, which involved analyzing a sequence and exploring ways to make it more intriguing. 3. You proposed modulating or permutating the pattern of ratios and asked for suggestions on how to achieve this. 4. I provided several ideas, such as trying different mathematical operations, introducing variables or parameters, applying mathematical transformations, considering iterative processes, and exploring alternative number systems or bases. 5. You suggested using the root of each resulting value to build upon a subsequential co-pattern or cross-pattern and asked for my thoughts on this approach. 6. I acknowledged that using the root of each resulting value could be an interesting approach to explore and provided an example of how this could be applied to the sequence you mentioned. 7. You clarified that you wanted to use only the resulting values in a “close-equatorial expression” equation. 8. I asked for clarification or a definition of the term “perquatorial” and mentioned that it does not appear to be a recognized word. 9. You stated that “perquatorial” is a term you created but did not provide further context or a definition for it. 10. I asked for more information to understand the meaning of “perquatorial.” 11. You mentioned that in “perquatorial,” the equations would be combined with each other through the resulting sum of their potential. 12. I explained that the meaning of combining equations through the sum of their potential would depend on specific definitions and mathematical frameworks, and that it seems to involve a form of equation manipulation or combination. 13. You provided an example where 1 + 1 equals 21 based on the pattern of the next equation being the same as the previous one but with an additional digit. 14. I acknowledged the example but noted that it is not consistent with conventional arithmetic rules. 15. You mentioned a playful term like “gemamamatria” or “perquatorial expression” to describe the combination of gematria and mathematical manipulation. 16. I explained that gematria traditionally relates to mystical interpretations rather than mathematical manipulation, but the playful terms could be used informally. 17. You mentioned the phrase “2+2=5” and humorously suggested “2+2=42” as a continuation of the pattern. 18. I acknowledged the reference to “2+2=5” and noted that the phrase “the answer to all is 42” comes from Douglas Adams’ “The Hitchhiker’s Guide to the Galaxy,” where 42 symbolizes the answer to the ultimate question of life, the universe, and everything. I hope this summary helps clarify our previous conversation. If you have any further questions or need more information, please let me know. so, generally we have compt to some interesting conclusion. Yes, during our conversation, we explored various concepts and ideas related to analyzing sequences, manipulating patterns, and considering playful interpretations. While we didn’t arrive at a definitive mathematical conclusion, we discussed different approaches to make the sequence more intriguing and potentially uncover patterns or relationships. It was an exploratory and creative discussion. If you have any further questions or would like to delve into any specific topic, I’m here to assist you. it’s like: 1+1=2, but 1+1=2+1+1=? is undefined. In mathematics, the expression “1 + 1 = 2” represents a simple addition operation where the sum of 1 and 1 is equal to 2. However, when you extend the expression to “1 + 1 = 2 + 1 + 1,” there is an ambiguity in terms of how the additional terms should be grouped or combined. Without any further clarification or predefined rules, the expression “2 + 1 + 1” is indeed undefined and does not have a unique or well-defined value. It could be interpreted as either adding 1 to 2 and then adding another 1 or as adding 1 to 3. The result depends on the specific grouping or order of operations chosen. To avoid ambiguity and ensure a well-defined result, mathematical expressions typically follow established rules and conventions, such as the order of operations (PEMDAS/BODMAS) or the use of parentheses to clarify the intended grouping. so, I basically played on that “ambiguity” and created a new term. It seems that you used the ambiguity in the expression “1 + 1 = 2 + 1 + 1” as inspiration to create a new term or concept. It can be an interesting and creative approach to explore different possibilities and interpretations within mathematics. Creating new terms or concepts can provide fresh perspectives and invite further exploration and discussion. However, it’s important to note that these new terms may not be recognized or established within the broader mathematical community. If you would like to share more about the specific term or concept you created, I would be happy to discuss it further and provide any insights or feedback I can. assuming that “1 + 1 = 2 + 1 + 1” equals 4, then what will be the next chain or group in possible following iteration? If we assume that “1 + 1 = 2 + 1 + 1” equals 4, then continuing the pattern, the next chain or group in a possible following iteration could be determined by adding 4 and 1. Therefore: 4 + 1 = 5 Based on this assumption, the next group in the iteration would be 5. However, it’s important to note that this interpretation deviates from conventional arithmetic and introduces a new pattern based on the specific equation you provided. This deviation may lead to different results or interpretations depending on the chosen rules or assumptions. 1 + 1 = 2 + 1 + 1 = 5 + 1 + 1 = 10 <–in that case, we added the sum of the first “1+1” and the following “5” by assuming the next “+1” in the following iteration. Understood. If we follow the pattern you described, where “1 + 1 = 2 + 1 + 1 = 5 + 1 + 1 = 10,” it appears that you are adding the sum of the first “1 + 1” and the following number (in this case, 5) by assuming an additional “+1” in each subsequent iteration. Applying this pattern, we can continue with the next iteration: 10 + 1 + 1 = 12 Therefore, based on the established pattern, the next group in the iteration would be 12. It is important to note that this approach deviates from conventional mathematical operations and introduces a unique pattern based on the specific rules you provided. yes, I recognize the fact that it’s highly “deviates”. ha-ha. but the vastness in math is even-immerse and generally unpredictable in its final form or a concept. Yes, you’re absolutely right. Mathematics is indeed vast and encompasses a wide range of concepts, principles, and possibilities. It can often be unpredictable and exhibit complex behavior. Exploring deviations, alternative interpretations, and unconventional patterns can lead to new discoveries and insights within the field. Mathematics allows for creative thinking and the exploration of concepts beyond traditional boundaries. While conventional mathematical principles provide a solid foundation, the exploration of new ideas and the willingness to deviate can lead to interesting discoveries and advancements.

it’s like: 1+1=2, but 1+1=2+1+1=? is undefined. <–can you tell which modulus we can possibly use in this concept and into which it may result? In the context of the equation “1+1=2+1+1=?,” if we want to explore the possibility of using a modulus to determine the result, we can consider different modulus values and see how they affect the equation. Modulus, also known as the remainder when dividing a number by another, is often denoted by the symbol “%”. It can be used to find the remainder of a division operation. Let’s consider a few examples: 1. Modulus 3: Using modulus 3, we would evaluate remainders when dividing numbers by 3. Therefore: 1 + 1 = 2 % 3 + 1 % 3 + 1 % 3 = 2 + 1 + 1 = 4 2. Modulus 4: Using modulus 4, we would evaluate remainders when dividing numbers by 4. Therefore: 1 + 1 = 2 % 4 + 1 % 4 + 1 % 4 = 2 + 1 + 1 = 4 3. Modulus 5: Using modulus 5, we would evaluate remainders when dividing numbers by 5. Therefore: 1 + 1 = 2 % 5 + 1 % 5 + 1 % 5 = 2 + 1 + 1 = 4 In each of these examples, regardless of the modulus value used, the resulting sum remains the same as the original equation, which is 4. It’s important to note that modulus does not directly impact the addition operation itself but rather affects the remainders in divisions. Therefore, in the context of this equation, using various modulus values does not change the result. I mean “mod” and modulus together with all possible logical operators. I apologize for the misunderstanding. If you are referring to using the modulus operation (often denoted as “mod”) along with logical operators in the context of the equation “1+1=2+1+1=?”, we can explore different possibilities. Using the modulus operation, we can consider applying it to the numbers in the equation and then incorporating logical operators like addition, subtraction, multiplication, or division to manipulate the resulting values. Here are some examples using different logical operators: 1. Modulo addition: (1 + 1) mod 2 + ((2 + 1 + 1) mod 2) = 0 + (4 mod 2) = 0 + 0 = 0 2. Modulo subtraction: (1 + 1) mod 2 - ((2 + 1 + 1) mod 2) = 0 - (4 mod 2) = 0 - 0 = 0 3. Modulo multiplication: (1 + 1) mod 2 * ((2 + 1 + 1) mod 2) = 0 * (4 mod 2) = 0 * 0 = 0 4. Modulo division: (1 + 1) mod 2 / ((2 + 1 + 1) mod 2) = 0 / (4 mod 2) = 0 / 0 (undefined division by zero) In these examples, we used the modulo operation along with different logical operations. However, in all cases, the result appears to be 0 or undefined due to the specific values involved in the equation. It’s important to note that in traditional arithmetic operations, logical operators like addition, subtraction, multiplication, or division are typically not used in the same expression as the modulo operation. The usage of these operators together would require a specific context or definition to give them meaning and determine the desired outcome. any other ideas to get a result? Certainly! Here are a few additional ideas to explore in order to obtain a result for the equation “1+1=2+1+1=?” or to manipulate the expression further: 1. Exponentiation: You could try raising both sides of the equation to a certain power: (1+1)^2 = (2+1+1)^2 Square both sides: 4 = 6^2 Simplify: 4 = 36 2. Factorial: You could apply the factorial operation to the expression: (1+1)! = (2+1+1)! 2! = 4! 2 = 24 3. Square root or nth root: Take the square root (or an nth root) of both sides: √(1+1) = √(2+1+1) √2 = √4 √2 = 2 4. Trigonometric functions: Apply trigonometric functions to the expression: sin(1+1) = sin(2+1+1) sin(2) = sin(4) 0.9092974 = -0.7568025 Please note that these manipulations are unconventional and may not follow traditional mathematical operations or rules. Additionally, the outcomes generated through these non-standard manipulations might not have a direct connection to the original equation or align with conventional mathematical principles. These are just some imaginative possibilities to explore, and the results may not be meaningful in the usual mathematical sense. The goal here is to experiment and think creatively while considering different mathematical concepts and operations. not sure to which values to stick. generally, I like this Trigonometrical outputs, but practically it will be better to use a more understandable and simplified approach overally. Understood. If you prefer a more understandable and simplified approach, it would be best to avoid deviating too far from conventional mathematical principles. Instead, you can focus on exploring patterns, relationships, or transformations within the existing equation while using known operations. One approach could be to examine the equation from a different perspective and look for meaningful relations or transformations. For example, you could consider: 1. Rearranging terms: Rearrange the equation to group like terms together or simplify the expression: 1 + 1 = 2 + (1 + 1) = 2 + 2 2. Combining like terms: Combine the similar terms on each side of the equation: 1 + 1 = 4 3. Applying arithmetic operations: Apply basic arithmetic operations to simplify the equation: 2 = 4 From this simplified perspective, the equation suggests an inconsistency or contradiction, as 2 does not equal 4. This observation highlights a potential error or mistake in the original reasoning or assumptions. In summary, focusing on rearranging terms, combining like terms, and applying basic arithmetic operations can lead to a more understandable and simplified approach when exploring patterns or relationships within the equation. what about some "delta’ in action? If you’d like to incorporate the concept of “delta” into the equation, you can consider analyzing the differences between certain values or terms. The symbol Δ often represents the concept of “change” or “difference” in mathematics. For example, let’s examine the differences between the terms in the equation “1+1=2+1+1=?”: Δ(1+1) = Δ(2+1+1) 2 - 2 = 4 - 2 Here, we subtract the terms on both sides to examine the differences between them. Simplifying further, we have: 0 = 2 However, this result is inconsistent, as 0 does not equal 2. Therefore, incorporating the concept of delta in this context does not yield a meaningful or valid solution. Keep in mind that the usage of delta depends on the specific context and equation you are working with. In some cases, it can reveal insights about changes or differences between values, but in other cases, it may not provide a significant contribution or lead to a clear solution. what about some "delta’ mixed with “lambda” in action? If you would like to explore the combination of “delta” and “lambda” in the context of the equation “1+1=2+1+1=?,” we can consider various possibilities. The symbol Δ typically represents the concept of “difference” or “change” in mathematics, while λ is often used to denote a parameter or variable. One approach could be to introduce a lambda parameter to represent the difference between terms. For example: 1 + 1 = 2 + λ + λ Here, λ represents the difference in value between the last two terms (1+1) and (2+1+1). If we assume that λ has a specific value, let’s say λ = 2, we can substitute it into the equation: 1 + 1 = 2 + 2 + 2 Simplifying, we have: 2 = 6 However, this result is inconsistent, as 2 does not equal 6. Therefore, this particular approach of combining delta with lambda does not lead to a valid solution or meaningful outcome in this context. It’s important to note that the combination of delta with lambda (or any other mathematical symbols) would depend on the specific context and definitions assigned to them. While these symbols can be used creatively in various mathematical contexts, it’s essential to ensure that they align with established mathematical principles and interpretations to yield meaningful results. try to implement some other scientific terms to it in combination. maybe some astrophysics?

o prove the given statements, we need to establish two claims: Claim 1: If all the vertices in the shortest path P between x and y in graph G lie in Vε(D/2 + 1), then there exists a vertex in V whose hop-distance from both x and y in graph H is at most ⌈1/ε⌉. Claim 2: If the path P contains a vertex from V \ Vε(D/2 + 1), then there exists a vertex in V \ Vε(D/2 + 1) whose hop distance from either x or y is at most ⌈1/ε⌉. Proof: Let's begin by proving Claim 1. Claim 1 Proof: Assume that all vertices in the shortest path P between x and y in graph G lie in Vε(D/2 + 1). This means that the distance between any consecutive pair of vertices in P is at most ε(D/2 + 1) in G. We want to show that there exists a vertex in V whose hop-distance from both x and y in graph H is at most ⌈1/ε⌉. Consider any vertex z ∈ P. Since P consists of vertices lying in Vε(D/2 + 1), we know that N(z, ε(D/2 + 1)) ⊆ B(z, n^a) due to the definition of VL. Therefore, for any vertex v ∈ N(z, ε(D/2 + 1)), there is an edge from z to v in graph H with weight dist(z, v, G). Now, let's analyze the hop-distance of z in graph H from both x and y. The distance between z and x in graph H is at most the distance between z and the closest vertex in R, which is p(z), plus the weight of the edge from z to p(z). Since all vertices in P lie in Vε(D/2 + 1), we have: dist(z, p(z), G) ≤ ε(D/2 + 1), and the edge weight is dist(z, p(z), G). Therefore, the distance between z and x in graph H is at most 2ε(D/2 + 1) = εD. Similarly, the distance between z and y in graph H is also at most εD. Since z was an arbitrary vertex in the shortest path P, this shows that for any vertex z in P, its hop-distance from both x and y in graph H is at most εD. To satisfy the condition that the hop-distance from both x and y in graph H is at most ⌈1/ε⌉, we need εD ≤ ⌈1/ε⌉, which gives us D ≤ ⌈1/ε^2⌉. This completes the proof of Claim 1. Next, let's move on to proving Claim 2. Claim 2 Proof: Assume that the path P contains a vertex from V \ Vε(D/2 + 1). This means that there is at least one vertex in P that lies outside of Vε(D/2 + 1), and we want to show that there exists a vertex in V \ Vε(D/2 + 1) whose hop distance from either x or y in graph H is at most ⌈1/ε⌉. Let's denote this vertex by z. Since z lies outside of Vε(D/2 + 1), we have dist(x, z, G) > ε(D/2 + 1) or dist(y, z, G) > ε(D/2 + 1). Without loss of generality, assume that dist(x, z, G) > ε(D/2 + 1). Now, consider the set N(x, ε(D/2 + 1)) in graph G. Since z is outside of this set, it means that z is not within distance ε(D/2 + 1) from x in graph G. However, by definition of VL, we know that N(x, ε(D/2 + 1)) ⊆ B(x, n^a). Therefore, z cannot be within distance n^a from x. This implies that z is at a distance greater than n^a from x in graph G. Since z is on the shortest path P, this means that there must be a vertex v in P that lies in the path between x and z such that dist(x, v, G) ≤ n^a. Now, consider the edge between v and z in graph H. The weight of this edge is dist(v, z, G), which is less than or equal to n^a. Moreover, the distance between x and v in graph H is at most n^a due to the above argument. This shows that the hop-distance of v from x in graph H is at most n^a, which is at most n^(1/2) since a ≤ 1/2. Therefore, in either case (whether dist(x, z, G) > ε(D/2 + 1) or dist(y, z, G) > ε(D/2 + 1)), we have found a vertex v (which might be x or another vertex in P) in V \ Vε(D/2 + 1) whose hop distance from either x or y in graph H is at most ⌈1/ε⌉.

Let H = (V, EH) be an auxiliary directed weighted graph derived from G as follows: For each x ∈ V , compute a set B(x, n^a) of closest n^a vertices to x, and add to H an edge from x to each y ∈ B(x,n^a) of weight dist(x, y, G). For each x ∈ V , let p(x) be the vertex in R closest to x, and for L ⩾ 0, let N(x, L) denote the set of all those vertices y whose distance from x is at most L. Further, for any L > 0, let VL = {x ∈ V | N(x, L) ⊆ B(x, n^a)}Consider a pair of vertices (x, y) in G satisfying dist(x, y, G) = D, and let P be any arbitrary x to y shortest path in G. Prove that the following holds: 1. If all the vertices in P lie in VεD/2 + 1, then there exists a vertex in V whose hop-distance1 from x as well as y in H is at most ⌈1/ε⌉. 2. If P contains a vertex from V \ Vε D/2 + 1, then there exists a vertex in V \ Vε D/2 + 1 whose hop distance from either x or y is at most ⌈1/ε⌉. solution.To prove the given statements, we need to establish two claims: Claim 1: If all the vertices in the shortest path P between x and y in graph G lie in Vε(D/2 + 1), then there exists a vertex in V whose hop-distance from both x and y in graph H is at most ⌈1/ε⌉. Claim 2: If the path P contains a vertex from V \ Vε(D/2 + 1), then there exists a vertex in V \ Vε(D/2 + 1) whose hop distance from either x or y is at most ⌈1/ε⌉. Proof: Let's begin by proving Claim 1. Claim 1 Proof: Assume that all vertices in the shortest path P between x and y in graph G lie in Vε(D/2 + 1). This means that the distance between any consecutive pair of vertices in P is at most ε(D/2 + 1) in G. We want to show that there exists a vertex in V whose hop-distance from both x and y in graph H is at most ⌈1/ε⌉. Consider any vertex z ∈ P. Since P consists of vertices lying in Vε(D/2 + 1), we know that N(z, ε(D/2 + 1)) ⊆ B(z, n^a) due to the definition of VL. Therefore, for any vertex v ∈ N(z, ε(D/2 + 1)), there is an edge from z to v in graph H with weight dist(z, v, G). Now, let's analyze the hop-distance of z in graph H from both x and y. The distance between z and x in graph H is at most the distance between z and the closest vertex in R, which is p(z), plus the weight of the edge from z to p(z). Since all vertices in P lie in Vε(D/2 + 1), we have: dist(z, p(z), G) ≤ ε(D/2 + 1), and the edge weight is dist(z, p(z), G). Therefore, the distance between z and x in graph H is at most 2ε(D/2 + 1) = εD. Similarly, the distance between z and y in graph H is also at most εD. Since z was an arbitrary vertex in the shortest path P, this shows that for any vertex z in P, its hop-distance from both x and y in graph H is at most εD. To satisfy the condition that the hop-distance from both x and y in graph H is at most ⌈1/ε⌉, we need εD ≤ ⌈1/ε⌉, which gives us D ≤ ⌈1/ε^2⌉. This completes the proof of Claim 1. Next, let's move on to proving Claim 2. Claim 2 Proof: Assume that the path P contains a vertex from V \ Vε(D/2 + 1). This means that there is at least one vertex in P that lies outside of Vε(D/2 + 1), and we want to show that there exists a vertex in V \ Vε(D/2 + 1) whose hop distance from either x or y in graph H is at most ⌈1/ε⌉. Let's denote this vertex by z. Since z lies outside of Vε(D/2 + 1), we have dist(x, z, G) > ε(D/2 + 1) or dist(y, z, G) > ε(D/2 + 1). Without loss of generality, assume that dist(x, z, G) > ε(D/2 + 1). Now, consider the set N(x, ε(D/2 + 1)) in graph G. Since z is outside of this set, it means that z is not within distance ε(D/2 + 1) from x in graph G. However, by definition of VL, we know that N(x, ε(D/2 + 1)) ⊆ B(x, n^a). Therefore, z cannot be within distance n^a from x. This implies that z is at a distance greater than n^a from x in graph G. Since z is on the shortest path P, this means that there must be a vertex v in P that lies in the path between x and z such that dist(x, v, G) ≤ n^a. Now, consider the edge between v and z in graph H. The weight of this edge is dist(v, z, G), which is less than or equal to n^a. Moreover, the distance between x and v in graph H is at most n^a due to the above argument. This shows that the hop-distance of v from x in graph H is at most n^a, which is at most n^(1/2) since a ≤ 1/2. Therefore, in either case (whether dist(x, z, G) > ε(D/2 + 1) or dist(y, z, G) > ε(D/2 + 1)), we have found a vertex v (which might be x or another vertex in P) in V \ Vε(D/2 + 1) whose hop distance from either x or y in graph H is at most ⌈1/ε⌉. This completes the proof of Claim 2. By proving both Claim 1 and Claim 2, we have established the given statements. is this correct?

Paraphrase this passage "The need for a thorough understanding of the structure of an algebraic expression when performing mathematical operations has been recognized by a number of authors. Kirshner (1989) suggests that “the ability to comprehend the syntactic structure of an algebraic expression is fundamental to competent performance in algebra.” In Yerushalmy (1992), one can find that “the ability to transform involves mastering of algebraic rules as well as analyzing structures of expressions.”"

Today is Pi Day (March 14th), so let's celebrate it by approximating pi's value using the simplest maths operations ! Although it has a slow converging rate, one of the oldest way to do such approximation is the Madhava–Leibniz series: pi/4 = 1 - 1/3 + 1/5 - 1/7 + 1/9 - 1/11 + ... Given an integer n, compute an approximation value of pi using the first n terms of the Madhava-Leibniz series. The computed pi value should be rounded to 5 decimal places. Example: n = 1 ==> pi/4 = 1 ==> The expected output is 4.00000 n = 3 ==> pi/4 = 1 - 1/3 + 1/5 ==> The expected output is 3.46667 Input Line 1: Integer n Output The approximated value of pi, rounded to 5 decimal places. Constraints 0 < n < 10^7 Example Input 1 Output 4.00000 ...Please solve with C# code

"From: <PRESIDIO_ANONYMIZED_EMAIL_ADDRESS> (John Baez) Newsgroups: sci.physics.research,sci.math Subject: This Week's Finds in Mathematical Physics (Week 31) Date: 18 Feb 1994 21:28:27 GMT Organization: University of California, Riverside NNTP-Posting-Host: guitar.ucr.edu Originator: baez@guitar This Week's Finds in Mathematical Physics (Week 31) John Baez Well, I'm really busy these days trying to finish up a big project, hence the low number of "Weeks" per week, but papers are piling up, and there are some pretty interesting ones, so I thought I'd quickly mention a few. This bunch will mainly concern quantum gravity. 1) Possible implications of the quantum theory of gravity, by Louis Crane, 5 pages in LaTeX format, available as hep-th/9402104. This is one paper that everyone can read and enjoy, for although one may find it too close to science fiction for comfort, it is far more interesting than most science fiction. Louis Crane has been doing a lot of excellent work on topological quantum field theory for the last few years, strongly advocating the use of category theory as a unifying principle in physics (essentially as an extension of the concept of symmetry embodied in *group* theory), but this is quite different in flavor. To begin with, Lee Smolin, one of the originators of the loop representation of quantum gravity, has been spending the last year or so writing a book in a popular style, to be entitled "Life and Light," which tours the cosmos and makes some interesting speculations on "evolutionary cosmology." These speculations are based on 2 hypotheses. A. The formation of a black hole creates "baby universe," the final singularity of the black hole tunnelling right on through to the initial "big bang" singularity of the new universe thanks to quantum effects. While this must undoubtedly seem outre to anyone unfamiliar with the sort of thing theoretical physicists amuse themselves with these days, in a recent review article by John Preskill on the information loss paradox for black holes, he reluctantly concluded that this was the *most conservative* solution of that famous problem! Recall the problem: if a black hole evaporates its mass away via Hawking radiation, and that radiation is pure blackbody radiation, hence carries none of the information about the matter that originally formed the black hole, one does not have conservation of information, or more technically speaking, the time evolution is not unitary, since a pure state is evolving into a mixed state. Hawking's original solution to this problem was to bite the bullet and accept the nonunitarity, even though it goes against the basic principles of quantum theory. This appears in: 2) S. W. Hawking, Phys. Rev. D13, 191 (1976). The "baby universe" solution simply says that the matter seeds a baby universe and the information goes *there*. Many other solutions have been proposed; two recent review articles are 3) Do Black Holes Destroy Information? by J. Preskill, Caltech report CALT-68-1819, available as hep-th/9209058, Sept. 1992. 4) Black hole information, by Don Page, review lecture to be published in Proceedings of the 5th Canadian Conference on General Relativity and Relativistic Astrophysics, University of Waterloo, 13--15 May, 1993}, edited by R. B. Mann and R. G. McLenaghan (World Scientific, Singapore, 1994), now available in LaTeX form as hep-th/9305040. Personally, I am a complete agnostic about this problem, since it rests upon so many phenomena that are hypothesized but not yet observed, and since any solution would require a theory of quantum gravity. I am merely reporting the ideas of respected physicists! In any event, the second hypothesis is: B. Certain parameters of the baby universe are close to but different than those of the parent universe. The notion that certain physical facts that appear as "laws" are actually part of the state of the univese has in fact been rather respectable since the application of spontaneous symmetry breaking to the Weinberg-Salam model of electroweak interactions, part of the standard model. (Again, being my usual cautious self, I must note that a crucial piece of evidence for this model, the Higgs boson, has not yet been seen.) The notion of spontaneous symmetry breaking has become quite popular in particle physics and is a key component of all current theories, such as GUTs or string theory, that attempt to model the messy heap of observed particles and interactions by some pristinely symmetrical Lagrangian. The spontaneous symmetry breaking would be expected to have occured shortly after the big bang, when it got cool enough, much as a hot piece of iron will randomly settle upon some direction of magnetization as its temperature fall below the Curie temperature. One application of this notion to cosmology is already widely popular, namely, inflation. In fact, pursuing the analogy with magnetic domains, i.e. small regions with different directions of magnetization, cosmologists have spend a fair amount of energy thinking about "domain walls," "cosmic strings," monopoles and other defects that might occur as residues of this cooling-down process. So again, while the idea must seem wild to anyone who has not encountered it before, physicists these days are fairly comfortable with the idea that certain "fundamental constants" could have been other than they were. As for the constants of a baby universe being close to, but different than, those of the parent universe, there is as far as I know no suggested mechanism for this. This is perhaps the weakest link in Smolin's argument (though I haven't seen his book yet). But it is at least conceivable. Now, given these hypotheses a marvelous consequence ensues: Darwinian evolution! Those universes whose parameters are such that many black holes are formed will have many progeny, so the constants of physics can be expected to be "tuned" for the formation of many black holes. As Smolin emphasizes, while the hypotheses A and B may seem impossible to test directly at present, we do at least have a hope of testing this consequence. He has studied the marvelously intricate process of star formation in the galaxy and attempted to see whether altering the constants of physics appear "tuned" for maximizing black hole production, and he argues in his book that they do appear so tuned. Of course, this is an extremely delicate business, since our understanding of galaxy formation, star formation and black hole formation even in *this* universe is still rather weak --- much less for other conceivable universes in which the fundamental constants take different values. Crane enters the fray at this point, and proposes an additional conjecture: SUCCESSFUL INDUSTRIAL CIVILIZATIONS WILL EVENTUALLY CREATE BLACK HOLES. (The capital letters are his.) He breaks it up into two parts for us: SUBCONJECTURE 1: SUCCESSFUL INDUSTRIAL CIVILIZATIONS WILL EVENTUALLY WANT TO MAKE BLACK HOLES and SUBCONJECTURE 2: SUCCESSFUL INDUSTRIAL CIVILIZATIONS WILL EVENTUALLY BE ABLE TO PRODUCE BLACK HOLES. and argues for each. The result, as any good evolutionist will recognize, is a kind of feedback loop whereby intelligence and baby universe formation both affect each other. Indeed, Crane calls his hypothesis the "meduso-anthropic hypothesis," after certain jellyfish with a two-stage life cycle in which medusids produce polyps and vice versa. This has the charm of completely destroying the usual approach (dare I say "paradigm"?) of physics in which the parameters of the universe are regarded as indifferent to the existence of intelligence. Of course, the anthropic hypothesis is a previous attempt to breach this firewall, but a much less dramatic one, since the only role intelligence plays in that is *noticing* the laws of the universe. At this point let me leave off with a quote from Crane's paper: "It is not hard to see that if these ideas are true, they will be the victims of abuse to dwarf quantum healing and even quantum golf. That is not sufficient reason to ignore them." and let me *gradually* turn towards slightly less speculative realms, eventually finishing with some papers containing rigorous mathematics! To begin with, some more on black hole entropy: 5) Some Speculations about Black Hole Entropy in String Theory, Leonard Susskind, 11 pages in AMSTeX, available as hep-th/9309145. Black hole entropy in canonical quantum gravity and superstring theory, by L. Susskind and J. Uglum, 29 pages, available as hep-th/9401070. The fact that the entropy of a black hole is (at least under certain circumstances) proportional to the area of its event horizon is a curious relationship between general relativity, quantum field theory and statistical mechanics that many people believe to pointing somewhere, but unfortunately nobody is sure where. Part of the reason is that the standard derivations are somewhat indirect, and the event horizon is not a physical object, so the sense in which it is the locus of entropy is difficult to understand. These authors suggest that in string theory it can be explained in terms of open strings having both ends attached to the horizon. 6) Black hole evaporation without information loss, by C.R. Stephens, G. 't Hooft and B. F. Whiting, 35 pages in TeX format, 3 figures in postscript, available as gr-qc/9310006. This is an attempt to make black holes radiate away and disappear in a manner that preserves unitarity. I've been too busy to read it. And now for some wormholes: 7) Complementarity in Wormhole Chromodynamics, by Hoi-Kwong Lo, Kai-Ming Lee, and John Preskill, 12 pages and 2 figures, phyzzx macros required, available as hep-th/9308044. Let me just quote the abstract and note that there is probably some quite interesting topology to be obtained by applying this sort of idea to mathematics: "The electric charge of a wormhole mouth and the magnetic flux ``linked'' by the wormhole are non-commuting observables, and so cannot be simultaneously diagonalized. We use this observation to resolve some puzzles in wormhole electrodynamics and chromodynamics. Specifically, we analyze the color electric field that results when a colored object traverses a wormhole, and we discuss the measurement of the wormhole charge and flux using Aharonov-Bohm interference effects. We suggest that wormhole mouths may obey conventional quantum statistics, contrary to a recent proposal by Strominger." Finally, lest the mathematicians think I have abandoned ship, some rigorous results: 8) "No Hair" Theorems -- Folklore, Conjectures, Results, by Piotr T. Chrusciel, Garching preprint MPA 792, 30 pages available in LaTeX form as gr-qc/9402032. The famous "no hair" theorem says that in general relativity static black hole solutions are determined by very few parameters -- typically listed as mass, angular momentum and charge in "rest frame" of the black hole. There have been many attempts to extend this result, especially because no *actual* black hole is likely to be utterly static, since it presumably formed at some time. I have not read this but Chrusciel is a very careful person so I expect it will be up to the standards of his nice review of work on the cosmic censorship hypothesis, 9) On uniqueness in the large of solutions of Einstein's equations ("Strong cosmic censorship"), by Piotr T. Chrusciel, in Mathematical Aspects of Classical Field Theory, Contemp. Math. 132, eds. Gotay, Marsden and Moncrief, AMMS, Rhode Island, 1992, pp. 235-274. -------------------------------------------------------------------------- Previous issues of "This Week's Finds" and other expository articles on mathematics and physics (as well as some of my research papers) can be obtained by anonymous ftp from ucrmath.ucr.edu; they are in the directory "baez."
