Symptoms Researchers have come to believe that mood disorders exist on a continuum from depression to mania;?? pure depression is thought to be much less common and some researchers consider it rare.?? In general, a person who has one of these conditions experiences symptoms across the spectrum but tends to lean more toward one end than the other.  ?? As they are trying to make a diagnosis, your doctor will ask you about where your symptoms typically fall on the spectrum. This will help them distinguish between depression and bipolar disorder. People who have depression with mixed features usually experience mostly depressive symptoms, but may have certain manic symptoms (such as racing thoughts) as well.?? To be diagnosed with major depressive disorder, you must have experienced certain symptoms every day for at least the past two weeks or longer.   Classic features of depression include low mood and decreased interest or pleasure in activities you typically enjoy. However, to be diagnosed with depression, you must also have at least four of the following symptoms:?? Fatigue, loss of energy and motivationFeeling worthless, ashamed, or guiltyInability to fall asleep or sleeping too muchTroubling thinking, focusing, and concentratingLosing or gaining weight, eating more or less than usualPsychomotor agitation (pacing, restlessness) or retardation (sluggish thought or movement)Recurrent thoughts of death/dying, suicidal ideation or attempts If your doctor feels you meet the criteria for a diagnosis of depression, the next step will be to determine whether you are also experiencing symptoms of hypomania or mania, such as:?? Elevated moodInflated self-esteemDecreased need for sleepRacing thoughts or flight of ideasBeing talkative or chatty, pressured speechIncreased energy or goal-directed activityParticipation in activities that may feel good at the moment but can have potentially serious consequences (i.e., excessive alcohol use, risky sexual behaviors, impulsive spending, etc.) If you have experienced at least three symptoms of hypomania or mania almost every day for the past two weeks of your current depressive episode, your doctor will add the specifier with mixed features to your depression diagnosis.??   Understanding Mania and Hypomania Causes The specific causes of depression with mixed features are unclear and not well understood.?? As with other types of depression, researchers suspect there are a number of different factors that contribute to the development of the MDD-MX, including an individual’s family history, genetics, environment, and other health conditions.   While MDD-MX can be difficult to diagnose, research has suggested it’s fairly common:?? As many as 25% of people with unipolar depression may have mixed episodes. Since the condition can easily be misdiagnosed as bipolar disorder, the number of people who have depression with mixed features may, in fact, be much higher.??   In the past, differentiating between depression with mixed episodes and bipolar disorder was much more challenging for clinicians.?? Recent updates to diagnostic guidelines that consider the subtleties of each condition have been helpful.?? Continued research into the factors that contribute to depression, such as environmental exposure and genetics, are also giving researchers a better understanding. Why Some People Are More Prone to Depression Diagnosis It can be very challenging to diagnose depression with mixed features. For a long time, mental health professionals were taught that the presence of manic symptoms meant a person had bipolar, rather than unipolar, depression.   While mania or hypomania is still part of the fundamental diagnostic criteria for bipolar disorder, it is now also understood that people with depression may also experience these symptomsâ€"albeit to a lesser degree.??   The classic signs and symptoms of major depression may be relatively easy to spot, but subtle episodes of mania or hypomania may go undetectedâ€"both by the person with the condition and the doctors treating them.?? How to Tell If Youve Had a Manic Episode A person with symptoms of hypomania or mania and depression may initially be misdiagnosed with bipolar disorder. While the conditions may look (and at times feel) the same, there are some important distinctionsâ€"especially when it comes to treatment. A correct diagnosis is necessary to ensure someone with either condition is able to access the most effective type of treatment.   Obvious similarities between mixed episodes of depression and bipolar disorder, such as shared symptoms, might be clear to doctors and researchers but these conditions may also share risk factors (like a family history of mental illness).   Doctors must carefully consider all the information as they are formulating a diagnosis, as only looking at symptoms can be misleading.?? The consequences of being diagnosed with the wrong mood disorder can have a major impact on someone’s life.??   According to the DSM-5, the with mixed features specifier can be added to a diagnosis of major depressive disorder to indicate that a person has symptoms of both depression and mania but doesn’t quite meet the diagnostic criteria for a diagnosis of bipolar disorder. Research has indicated that compared to those with depression, people who experience mixed episodes are more likely to misuse substances?? and are at an increased risk for suicide?? â€"yet another reason why getting a correct diagnosis is important.   Treatment After being diagnosed with depressive disorder with mixed features, your doctor or psychiatrist will discuss treatment options with you. The first option may be therapy, medication, or both. Though there are similarities between depression with mixed features and bipolar disorder, the two conditions can differ quite a bit in how they respond to treatmentâ€"especially medications.?? It’s important to know that this form of depression may not respond wellâ€"or at allâ€"to treatment with antidepressant medications alone.?? It’s also important to know that a diagnosis of depressive disorder with mixed features in and of itself is a significant risk factor for eventually developing bipolar disorder.?? When you and your doctor are creating a treatment plan, you will need to consider this risk.   To help with manic symptoms, your doctor may also prescribe an atypical antipsychotic such as:   Saphris (asenapine)Latuda (lurasidone)Zyprexa (olanzapine)Seroquel (quetiapine)Geodon (ziprasidone) You may also be given a mood stabilizer like lithium or Depakote (divalproex) instead of, or in addition to, an antidepressant. Small studies in people with depression and mixed episodes have demonstrated that these medications may be helpful when given in doses lower than would be used for bipolar disorder.??   Some people who have depression with mixed features have trouble sleeping or feel especially agitated during periods of mania/hypomania. Your doctor may prescribe  sedatives to help with these symptoms, such as: Valium (diazepam)Xanax (alprazolam)Ativan (lorazepam)Klonopin (clonazepam) Even if you are taking more than one medication, it may not be enough to effectively help manage symptoms of depression with mixed features.?? You may need to implement other types of treatment as well, such as psychotherapy or electroconvulsive therapy (ECT). Coping For people who have MDD-MX, both the process of getting diagnosed and the demands of managing symptoms can become frustrating and overwhelming. If you have recently been diagnosed or are working with a doctor or mental health professional because you suspect you may have depressive disorder with mixed features, it’s important that you have the support you need.??   Begin to build your network of support with those around you at home, such as family members and friends, then reach out to your community (such as a church group or volunteer organization).   You may want to find specific support groups (in-person, online, or both) for people with depression, bipolar disorder, and other mood disorders.   If you’re not sure where to start, ask your doctor, psychiatrist, or therapist if they can point you toward local resources. You can also use the internet to search for social networks, forums, and patient advocacy networks. The Best Online Resources for Depression A Word From Verywell If you have depression with mixed features, you may share some experiences with someone who has been diagnosed with bipolar disorder. However, the conditions have some key differences that both you and your mental health care team need to be aware ofâ€"especially when deciding on treatment.  ?? The process can be frustrating, particularly if you are initially misdiagnosed with another mood disorder and not given a treatment that works well for you. That’s why it’s important to do your best to create and maintain a network of support around you.   Can Depression Turn Into Bipolar Disorder?

Privacy Concerns Over The Google Glass - 1888 Words

Womens Freedom during Chinas Revolutionary Period Essay

Womens Freedom during Chinas Revolutionary Period During the revolutionary period in China from 1921 to 1934, although there were undercurrents of an actual feminist movement, according to Kay Ann Johnson in Women, the Family Peasant Revolution in China, women’s progress resulted more as a necessity of the war than the leadership’s commitment to emancipate women. Furthermore, when tension arose between men and women, the leadership usually appeased men over women. By not discussing the mentality of the political parties and the dynamics of the war, Hughes and Hughes’ critique lacks an explanation of the underlying motives that drove these parties to sometimes support women and other times reject women’s interests.†¦show more content†¦Hughes and Hughes refer to the Guomindang (KMT), another revolutionary party, that issued demands â€Å"for equality between the sexes, permission for women to inherit property, [and] free marriage and divorce† (HH 236). However, Hughes and Hughes do not fully explain the tensions and underlying reasons for the CCP’s support of women. Johnson, on the other hand, argues that from the onset, the â€Å"Party distrusted the feminist groups themselves as elitist, bourgeois reformers† (Johnson 40). Therefore, any progress made by the Party in favor of women was not true emancipation but emancipation disguised under ulterior motives. Instead, the Party deemed women’s reforms advantageous to their political strategy and position in the war. For example, after 1928, the Communists’ policies were aimed at increasing women’s activities that supported the war effort and the economy. It became important for the Party to win women’s support because women were able to affect men’s decisions. Sometimes women would attempt to dissuade their husbands or sons from joining the army. Therefore, by gaining women’s support, men’s participation in the ar my would increase. In addition, being able to teach women agricultural duties greatly increased the availability of men for battle.

Compensated Demand Curve Free Essays

string(50) " where there is now a horizontal intercept of 50\." The Compensated Demand Curve Definition: the compensated demand curve is a demand curve that ignores the income effect of a price change, only taking into account the substitution effect. To do this, utility is held constant from the change in the price of the good. In this section, we will graphically derive the compensated demand curve from indifference curves and budget constraints by incorporating the substitution and income effects, and use the compensated demand curve to find the compensating variation. We will write a custom essay sample on Compensated Demand Curve or any similar topic only for you Order Now Let us consider a price increase for a normal good, a good whose demand increases as income increases. In Figure 7. e. 1, assume that the price of Y (PY) is $1, and that the individual has an income of $100. The initial price of X (PX) is $1, so the individual’s initial budget constraint is therefore BC1, with a vertical intercept of 100, and a horizontal intercept of 100. The individual reaches his optimum (maximizes utility) at point A, where his initial budget constraint BC1 is tangent to the indifference curve IC1. Let’s say that at this point, he maximizes his utility by consuming 43 units of good X. If PX increases from $1 to $2, his budget constraint will rotate inward until it reaches BC2 where there is now a horizontal intercept of 50. You read "Compensated Demand Curve" in category "Papers" The individual now reaches his new optimum where the indifference curve IC2 is tangent to BC2 at the point B, where he maximizes his utility by consuming 18 units of good X. We can use these points to plot a demand curve for good X: According to Figure 7. e. 1, when PX is $1, the individual maximizes utility at point A where he consumes 43 units of X. This information can be replotted on a curve showing the relationship between the price of X and the quantity of X consumed (figure 7. e. 2). At a price of $1, the individual will consume 43 units of X, so the point A will replot on figure 7. e. 2 as the point A’. Similarly at point B, at a price of $2, the individual will consume 18 units of X, so the point B will replot on figure 7. e. 2 as the point B’. If we connect A’ and B’ together, we will get the ordinary demand curve for good X In order to obtain the compensated demand curve, we must first observe 2 effects that take place as PX increases: Substitution Effect: when Px increases from $1 to $2, X becomes relatively more expensive than Y, so the individual consumes less X. To show the substitution effect, we must hold the individual’s utility constant. To do this, we draw a budget constraint BC3 that is parallel to BC2 and shift it up until it is just tangent to a point on his original indifference curve (IC1). This occurs at point C, where the consumer is consuming 29 units of X. The substitution effect is the movement from point A to C Income Effect: because Px has increased, the individual’s purchasing power has decreased, and thus has less money to spend on both X and Y. Because X is a normal good, the individual will consume more as his income increases. The individual will reach an optimum at point B where he will consume 18 units of X. The income effect is the movement from point C to B To summarize, Total effect = Substitution Effect + Income Effect = A to C +C to B We have already found the ordinary demand curve by replotting points A and B as points A’ and B’. In essence, this is the total effect of the increase in PX. Because the compensated demand curve assumes that utility is held constant, it only shows the substitution effect. Therefore, we simply have to replot points A and C. We have already determined that point A replots as A’ at a price of $1 and a quantity of 43. At point C, the individual consumes 29 units at a price of $2; so we can replot this point as point C’ on figure 7. e. 2. If we connect these 2 points together, we get the compensated demand curve. We can prove that good X is a normal good. One way to do it is to look at Figure 7. e. and notice that between points B and C, as income increases, the consumption of good X increases, which fits the definition of a normal good. Another way is to look at the compensated demand curve and compare it with the ordinary demand curve. The compensated demand curve in figure 7. e. 2 is steeper than the ordinary demand curve. When this condition holds, good X is a normal good. We can also use the compensated demand curve to find the compensating variation. The compensating variation is the amount of money required to restore an individual to his original utility level when prices change. In figure 7. e. 2, it is represented by the area between the two prices, and left of the compensated demand curve – it is the sum of areas S and T. Meanwhile the change in consumer surplus is simply the area between the two prices and left of the ordinary demand curve – it is the area S ——————————————————————————————————————————————– †¢ Next, consider a price decrease for an inferior good, a good whose demand decreases as income increases. In Figure 7. e. 3, assume that the price of Y (PY) is $1, and that the individual has an income of $100. The initial price of X (PX) is $2, so the individual’s initial budget constraint is therefore BC1, with a vertical intercept of 100, and a horizontal intercept of 50. The individual reaches his optimum (maximizes utility) at point A, where his initial budget constraint BC1 is tangent to the indifference curve IC1. Let’s say that at this point, he maximizes his utility by consuming 17 units of good X. If PX decreases from $2 to $1, his budget constraint will rotate outward until it reaches BC2 where there is now a horizontal intercept of 100. The individual now reaches his new optimum where the indifference curve IC2 is tangent to BC2 at the point B, where he maximizes his utility by consuming 28 units of good X. Using the same method as described in figure 7. e. 1 and figure 7. e. 2, we can replot A and B on figure 7. e. 3 as A’ and B’ on figure 7. e. 4. If we connect these points together, we will get the ordinary demand curve for good X In order to obtain the compensated demand curve, we must first observe 2 effects that take place as PX increases: Substitution Effect: when Px decreases from $2 to $1, X becomes relatively cheaper than Y, so the individual will consume more X. To show the substitution effect, we must hold the individual’s utility constant. To do this, we draw a budget constraint BC3 that is parallel to BC2 and shift it down until it is just tangent to a point on his original indifference curve (IC1). This occurs at point C, where the consumer is consuming 33 units of X. The substitution effect is the movement from point A to C Income Effect: Px has decreased, so the individual’s purchasing power has increased, and thus has more money to spend on both X and Y. Because X is an inferior good, the individual will consume less as his income increases. The individual will reach an optimum at point B where he will consume 28 units of X. The income effect is the movement from point C to B To summarize, Total effect = Substitution Effect + Income Effect = A to C +C to B Using the same method as described in figure 7. . 1 and figure 7. e. 2, we can replot A and C on figure 7. e. 3 as A’ and C’ on figure 7. e. 4. If we connect these points together, we will get the compensated demand curve for good X We can prove that good X is an inferior good. One way to do it is to look at Figure 7. e. 3 and notice that between points B and C, as income increases, the consumption of good X decreases, which fits the definition of an inferior good. Anothe r way is to look at the compensated demand curve and compare it with the ordinary demand curve. The compensated demand curve in figure 7. e. 4 is flatter than the ordinary demand curve. When this condition holds, good X is an inferior good. Again, we can also use the compensated demand curve to find the compensating variation. It is the area between the two prices, and left of the compensated demand curve – it is the sum of areas S and T ——————————————————————————————————————————————– †¢ Let us now consider a price decrease for an extreme case: a giffen good. A giffen good violates the law of demand and results in an upward sloping demand curve. In Figure 7. e. 5, assume that the price of Y (PY) is $1, and that the individual has an income of $100. The initial price of X (PX) is $1, so the individual’s initial budget constraint is therefore BC1, with a vertical intercept of 100, and a horizontal intercept of 50. The individual reaches his optimum (maximizes utility) at point A, where his initial budget constraint BC1 is tangent to the indifference curve IC1. Let’s say that at this point, he maximizes his utility by consuming 37 units of good X. If PX decreases from $2 to $1, his budget constraint will rotate outward until it reaches BC2 where there is now a horizontal intercept of 100. The individual now reaches his new optimum where the indifference curve IC2 is tangent to BC2 at the point B, where he maximizes his utility by consuming 30 units of good X. The total consumption of good X has actually decreased; let us decompose this. Using the same method as described in figure 7. e. 1 and figure 7. e. 2, we can replot A and B on figure 7. e. 5 as A’ and B’ on figure 7. e. 6. The shape of the ordinary demand curve for a giffen good is as follows: between the points A and B, it is upward sloping (known as the â€Å"Giffen Range†), and at any price above or below points A and B, respectively, the demand curve is downward sloping. This results in a backward-bending ordinary demand curve W In order to obtain the compensated demand curve, we must first observe 2 effects that take place as PX increases: Substitution Effect: when Px decreases from $2 to $1, X becomes relatively cheaper than Y, so the individual will consume more X. To show the substitution effect, we must hold the individual’s utility constant. To do this, we draw a budget constraint BC3 that is parallel to BC2 and shift it down until it is just tangent to a point on his original indifference curve (IC1). This occurs at point C, where the consumer is consuming 47 units of X. The substitution effect is the movement from point A to C Income Effect: Px has decreased, so the individual’s purchasing power has increased, and thus has more money to spend on both X and Y. Because X is a giffen good, the individual will consume less as his income increases; also note that the income effect is stronger than the substitution effect. This results in the individual reaching an optimum at point B where he will consume 30 units of X. The income effect is the movement from point C to B To summarize, Total effect = Substitution Effect + Income Effect = A to C +C to B Using the same method as described in figure 7. e. 1 and figure 7. e. 2, we can replot A and C on figure 7. e. 5 as A’ and C’ on figure 7. e. 6. If we connect these points together, we will get the compensated for good X Note that the compensated demand curve is still downward sloping. This is because the substitution effect always works in one direction, while the income effect can work in both directions Study Questions 1) Redraw figure 7. e. 1 and figure 7. e. 2 for a decrease in the price of a normal good. Shade the area representing the compensation variation. 2) Redraw figure 7. e. 3 and figure 7. e. 4 for an increase in the price of an inferior good. Shade the area representing the compensation variation. 3) Redraw figure 7. e. 5 and figure 7. e. 6 for an increase in the price of a giffen good. Shade the area representing the compensation variation. How to cite Compensated Demand Curve, Papers

Massacre at Mystic Essay Example

Massacre at Mystic Paper Day 1: Massacre at Mystic The first day took place on May 26th, 1637 in a Pequot village at Missituck (located near the Mystic River in Connecticut). What happened was the English and Indian allies had attacked the Pequot village. Within that group, there were 70 English, 70 Mohegans, and 500 Narragansetts. The Mohegans and the Narragan were the allies of the English. The English were Puritans from the Massachusetts Bay Colony, led by Major John Mason and Captain John Underhill. The massacre was the first time the English had been involved in the killings of Native Americans. The purpose of the Puritans migrating to America was to start a new life and for religious freedom from England. The Pequot village was the wealthiest, largest, and powerful tribe of Connecticut. The Pequots were also dominant in military and political force. Part of the Massacre at Mystic started when two â€Å"Block Islanders,† who were thought to be Pequot but were really a subtribe of the Narragansett, pretended to seek trade with John Oldham. Once they were aboard his ship, they killed him and stole all of his goods. Along with the murder of Oldham, the murder of John Underhill also led to John Endicott seeking revenge on the Pequots. The Puritans officially declared when the Pequot started killing colonists, capturing women, slaughtering livestock, and burning storehouses from the English Population. The battle lasted less than an hour. The English captured whoever they could find and beheaded them and tortured them, among with other things.

Once they finally found him, the English tried to negotiate the release of 200 women and children, but he slipped away. He later had his head cut off from trying to get help from the Mohawk, who were Sassacus’ old enemies, and they sent it to the English as a token of friendship. The war officially ended in September 1638 when tribal leaders that were left signed the Treaty of Hartford. This treaty revoked legal recognition of the Pequot nation.

Crusades essays

Crusades essays Through out time, history has had a tendency to repeat it self. It has done so in good means as well as bad. People learn from the past and apply it to their every day lives. Although people try to do the right thing and not follow mistakes that have been already made, they just seem to come about. This day in age, out country is experiencing a situation that is extremely similar to that that occurred in the 11th, 12th, and 13th centuries, that which is the crusades. Crusades now can be defined as all wars undertaken in pursuance of a vow, and directed against infidels. But back in the middle ages it was known as any military expedition under taken by the Christians of Europe (Random House Websters 318). On September 11,2001 the people of America as well as all other free countries in our nation experience a new feeling that we have not know of. We were being attacked for our beliefs, for the way we live our lives. This what we were feeling, was being fought for during the time of the Crusades. The Christians and the Muslims were fighting against one another in order to spread their religion, or end the other. The people who were the leaders of the attack were Muslims. Muslims are people who follow the religion of Islam. Islam is a religion that was founded by a man named Muhammad. The followers of Muhammad believe that he received messages from God. Those messages all established into the rules that the Muslims live by, and they are all recorded in the Koran. Some of the laws forbade Muslims to eat pork, drink alcohol, gamble or lend money for interests. But the main beliefs of the Muslims are The Five Pillars. Which are to have faith in God (Allah). To pray five times a day facing in the direction of Mecca. For a person to give part of their income to charity. To fast during the month of Ramadan, and to promise to go on a pilgrimage to Mecca at least ounce in your life. The event leading u...

Understanding Earth and its History

Understanding Earth and its History We live in an interesting time that allows us to explore the solar system with robotic probes. From Mercury to Pluto (and beyond), we have eyes on the sky to tell us about those distant places. Our spacecraft also explore Earth from space and show us the incredible diversity of landforms our planet contains. Earth-observing platforms measure our atmosphere, climate, weather, and study the existence and effects of life on all the planets systems. The more scientists learn about Earth, the more they can understand its past and its future.   The name of our planet comes from an Old English and Germanic term eorà °e. In Roman mythology, the Earth goddess was Tellus, which means the fertile soil, while the Greek goddess was Gaia, terra mater, or Mother Earth. Today, we call it Earth and are working to study all its systems and features.   Earths Formation Earth was born  some 4.6 billion years ago as an interstellar cloud of gas and dust coalesced to form the Sun and rest of the solar system. This is the birth process for all stars in the universe. The Sun formed at the center, and the planets were accreted from the rest of the material. Over time, each planet migrated to its present position orbiting the Sun. The moons, rings, comets, and asteroids were also part of solar system formation and evolution. Early Earth, like most of the other worlds, was a molten sphere at first. It cooled and eventually its oceans formed from water contained in the planetesimals that made the infant planet. Its also possible that comets played a role in seeding Earths water supplies.   The first life on Earth arose some 3.8 billion years  ago, most likely in tidal pools or on the seabeds. It consisted of single-celled organisms. Over time, they evolved to become more complex plants and animals. Today the planet hosts millions of species of different life forms and more are being discovered as scientists probe the deep oceans and polar ices. Earth itself has evolved, too. It began as a molten ball of rock and eventually cooled. Over time, its crust formed plates. The continents and oceans ride those plates, and the motion of the plates is what rearranges the larger surface features on the planet. The known contents of Africa, Antarctica, Asia, Europe, North and South America, Central America, and Australia, are not the only ones Earth has had. Earlier continents are hidden underwater, such as Zealandia in the south Pacific.   How Our Perceptions of Earth Changed Early philosophers once put Earth at the center of the universe. Aristarchus of Samos, in the 3rd century B.C.E., figured out how to measure the distances to the Sun and Moon, and determined their sizes. He also concluded that Earth orbited the Sun, an unpopular view until Polish astronomer Nicolaus Copernicus published his work called  On the Revolutions of the Celestial Spheres  in 1543. In that treatise, he suggested a heliocentric theory that Earth was NOT the center of the solar system but instead orbited the Sun. That scientific fact came to dominate astronomy and has since been proven by any number of missions to space. Once the Earth-centered theory had been put to rest, scientists got down to studying our planet and what makes it tick. Earth is composed primarily of iron, oxygen, silicon, magnesium, nickel, sulfur, and titanium. Just over 71% of its surface is covered with water. The atmosphere is 77% nitrogen, 21% oxygen, with traces of argon, carbon dioxide, and water. People once thought Earth was flat, but that idea was put to rest early in our history, as scientists measured the planet, and later on as high-flying aircraft and spacecraft returned images of a round world. We know today that Earth is a slightly flattened sphere measuring 40,075  kilometers around at the equator. It takes 365.26 days to make one trip around the Sun (commonly called a year) and is 150 million kilometers away from the Sun. It orbits in the Suns Goldilocks zone, a region where liquid water can exist on the surface of a rocky world.   Earth has only one natural satellite, the Moon at a distance of 384,400 km, with a radius of 1,738 kilometers and a mass of 7.32 Ãâ€" 1022  kg. Asteroids 3753 Cruithne and 2002 AA29 have complicated orbital relationships with the Earth; theyre not really moons, so astronomers use the word companion to describe their relationship with our planet.   Earths Future Our planet will not last forever. In about five to six billion years,  the Sun will begin to swell up to become a red giant star. As its atmosphere expands, our aging star will engulf the inner planets, leaving behind scorched cinders. The outer planets may become more temperate, and some of their moons could sport liquid water on their surfaces, for a time. This is a popular meme in science fiction, giving rise to stories of how humans will ultimately migrate away from Earth, settling perhaps around Jupiter or even seeking out new planetary homes in other star systems. No matter what humans do to survive, the Sun will become a white dwarf, slowly shrinking and cooling over 10-15 billion years. Earth will be long gone.   Edited and expanded by Carolyn Collins Petersen.
