What is Schizophrenia?
Many people think people with schizophrenia have a ‘split personality’. Perhaps this comes from Robert Louis Stevenson’s classic novel, ‘Dr Jekyll and Mr Hyde’, in which the sane and upright doctor, experimenting with mind-altering drugs, descends into the near-bestial Hyde with tragic results. But schizophrenia, which affects one in every 125 people worldwide, is not really like this.
It is true that ‘schizo’, from Ancient Greek, means split. The ‘phrenia’ part is harder to translate. ‘Phrenum’ originally meant ‘bit’ or ‘bridle’, something assisting a rider in controlling a horse. In human anatomy, the word came to refer both to the diaphragm, the membrane that rises and falls with our breathing, and to our minds, to what goes on inside our heads. Schizophrenia, then, can literally mean ‘split-mind’, renowned psychiatrist, Professor Nancy Andreasen’s phrase, ‘broken brain’, used in the title of one of her books.
Susceptible people usually develop schizophrenia in their teens or early twenties. Before that, their brains and minds seem to be working okay. Then something goes wrong. The brain gets broken. Mental functions go awry… But nobody has yet discovered precisely what is at the heart of the problem. Biological factors – including abnormal brain anatomy, alterations in brain chemistry, genetic influences, and/or the effects of toxic substances (including cannabis and other drugs) – are strong possibilities that have been investigated. Psychological factors – such as early losses and other forms of emotional trauma – must be considered too.
Any or all of these various factors, plus others perhaps, may combine to produce the mental illness (or group of related illnesses) we call schizophrenia. About one-third of people who get it later recover. About one-third have a fluctuating course, with variations in intensity and periods of partial or complete remission; and about one-third experience more or less permanent symptoms and associated disabilities.
Treatment with medication (‘anti-psychotics’) can help reduce symptom intensities, suppressing some or all symptoms, but the illness process continues, so that stopping medication results in the symptoms returning.
Working with people with schizophrenia for many years has taught me much. To me, they are always ‘people with schizophrenia’, never ‘schizophrenics’. The disease label is utterly insufficient to define everything that these individuals have been, are now, and might become. To use it that way is an insult.
A typical person will have been doing fine at home and school when something starts to go wrong. For many patients, it is as if the focus of consciousness starts blinking, switching rapidly on and off, occasionally at first, and then more consistently. There are mini-gaps in the flow of mental activity. Imagine watching a television programme, then the screen very briefly goes blank, and when the picture and sound return the set is tuned to another channel and another programme. You start watching that, and then it happens again. You try and get back to the first programme, but the harder you try, the more frequently the blank screen effect cuts in.
This may be the basic fault in schizophrenia. Most of the other symptoms can be attributed to this fundamental imperfection, a repeated interruption to the flow of thoughts and sensations. When this starts happening, there is a tendency to open up to the inner world of experiences, paying less attention to whatever is going on in the environment. There are strong suggestions that the basic fault is linked – whether as cause or effect – to a persistent overload of stimulation. Colors or sounds may, for example, seem exceptionally vivid or altered in character. This can all be very disconcerting.
It is wise to think of the young person with schizophrenia as having a healthy functioning mind trying to make sense of, and get under better control, the part of itself which is broken. Successful mental health professionals always try to work with this healthy part, even when the symptoms seem overwhelming.
When the mind blinks, so to speak, goes blank briefly and keeps switching channels, the person’s thoughts become vague, elliptical and obscure. He or she can no longer easily, therefore, master and follow a series of instructions, or plan and carry out a course of actions. Often feeling impotent and useless, they may respond badly when pressure is put on them to achieve in the way they had been able to before the onset of the disorder.
Irritability is common. The person naturally feels a deep sense of being invaded. Their thoughts, feelings and actions seem to be known to other people, as if perhaps inserted into or withdrawn from their minds by others. By way of explanation, they readily develop false beliefs about being targeted and persecuted. They mistrust people, including close family members, who are themselves having difficulty understanding what seems to be happening, and the person’s changed pattern of behavior. Affected people may, for instance, isolate themselves much of the time, as a way of coping with the sensations of outside interference, as well as the demands of well-meaning but misplaced encouragement. Another symptom, hallucinatory voices, that are often highly critical, may add to the person’s feelings of persecution.
In the early stages, a teenager or young adult, will only rarely consider (much less like the idea) that they have a mental illness and go for professional help. Usually, the person keeps quiet about it. With difficulty concentrating, in class for example, he or she may try harder at first, in an almost obsessional way. Eventually, though, unable to keep up, it is common for such a person to fall behind and, often, to drop out of school, or later to give up their employment. He or she may self-medicate with so-called ‘recreational’ drugs and/or alcohol, in unwise amounts, as another (ultimately self-defeating) way of trying to cope with the symptoms.
Much has been written about the emotional state of people with schizophrenia, and how their mood can often appear shallow, volatile or incongruous. Some forms of schizophrenia are thought to include a depressive component as part of the illness process. However, great care should be taken when interpreting a person’s emotional reaction to very challenging, often bizarre internal mental experiences and their consequences.
With the healthy part of their mind working alongside the broken elements, a person might naturally seek to minimize external stimuli and close down their emotional responsivity. Those who seem apathetic, dull and closed off, hard to reach and communicate with, are often super-sensitive, sometimes instinctively feeling the raw emotional state of other people better than those people do themselves. Social withdrawal is, for them, an important and understandable form of self-defence.
The healthy mind of the sufferer will also recognize that, unable to finish school, he or she will be unable to find decently paid employment, and will not be attractive to others, and so less likely to find a life-partner. With poor job and marriage prospects, and low income, they will miss out on many of the things that seem necessary for simple human happiness. They may well, in a natural and healthy way, feel unhappy about that, perhaps angry too, or ashamed. There is, in other words, even at a young age, a good deal of grieving to be done, and new, appropriate, reachable goals to be set, once optimal treatment and symptom control have been reached.

People who say these things make me want to punch babies.
Not only does every engineer/mathematician/physicist/computer scientist (amongst several others I’m not listing and subcategories of each of these) use shitloads of complex math, but every single object and device you use in your non-math-related job was built and/or works thanks to math. 
Literally. Everything.
Stop complaining about math being something useless you had to struggle with in high school. Even if you never had to calculate a derivative ever again, it certainly did more good to your brain than that easy class you liked because you aced with no effort. Math is (or I guess was) good for you.  
Yes, it’s hard. It’s really hard. Like…shit. Math is hard. And we all do suck at it at first (and by “at first” I mean for a veeery long time). But I cannot bring myself to understand these people in their 20s and 30s that keep bringing back the same topic: “Ugh, why did I have to learn math at school? I never used a trig identity in my life!” Yeah, and you never had to know that the French Revolution started in 1789 and that an anastrophe is a literary device wherein you switch the noun and adjective because it adds a more poetic style.
But math is everywhere in your life and you better damn well appreciate it.

Anonymous asked: Light both ends of the first string. After it burns, light one end of the other.

I’m not sure who you are, but if this answer is correct, then my previous answer is also correct, and only uses one match. For this answer can only be true if the rate at which the string burns is constant. The reason for this is that this answer assumes that lighting both ends of the string will make it burn twice as fast, which is logically equivalent to assuming that the rate at which the string burns is constant.

Or am I still completely off the mark?

EDIT: I just read my previous answer, and to avoid confusion, I’ll add that where I say here that ‘the rate at which the string burns is constant’, I say in my previous post about this that ‘it burns evenly’.

These two equations form the kernel for Einstein’s Special Relativity.  They are the reason that both time and distance become elastic at speeds close the the speed of light.
v is the velocity of an alternate frame of reference.
x,t are the displacement and time in my frame.
x’, t’ are the displacement and time in the moving frame.
c is the speed of light.
When these equations are re-arranged to solve for x and t (instead of x’ and t’), incredibly, the same equations result (only with v replaced by -v).  One result: if time seems to me to slow in the moving frame of reference, then to the moving frame of reference, my time seems to slow as well!

MY THOUGHTS ARE THAT HYPERVELOCITY STARS ARE REALLY RAD
LET ME TELL YOU ABOUT THEM
Also known as ‘rogue stars’, hypervelocity stars are basically stars that have been kicked out of their own galaxies and are now hurtling through intergalactic space. Six such stars have been discovered on the outskirts of the Milky Way, standing out due to their lonely location between the Milky Way and Andromeda galaxies, and by their red colouration.
The stars are thought to be red giants, with something called high metallicity. “Metallicity” is a proportional measure of the chemical elements (other than hydrogen and helium) that a star contains. The high metallicty of these hypervelocity stars indicates they were formed in the inner galactic regions—so they’re believed to have been ejected from the heart of our galaxy.

Evidence indicates that a supermassive black hole resides at the centre of the Milky Way, and it’s like a gravitational monster, jamming the mass of four million suns into a space smaller than Earth’s orbital region. But the stars didn’t come FROM the black hole—nothing can escape a black hole (except Hawking Radiation). To escape the gravitational grasp of our galaxy, hypervelocity stars need to be travelling incredibly fast—like over three million kilometres per hour fast—and one of the only things that could give stars such a kick is a close encounter with a supermassive black hole.
Since its gravitation field would be strong enough to accelerate stars to hypervelovity, astronomers basically think that the black hole at the centre of our galaxy acts as a slingshot. Typically, a binary star system would get caught in the black hole’s grip, and while one gets sucked in, the other one is flung away at enormous speeds. Another scenario could occur when a black hole is ingesting another, smaller black hole, and a star that ventures close to the circling pair could get a kick, like stellar pinball.
These hypervelocity stars would have been smaller, yellow stars like our own sun when they first got this kick, but even travelling at such huge speeds, it would’ve taken them around 10 million years to traverse 50,000 light years to the edge of the Milky Way. That’s why the stars detected are red giants, near the end of their stellar evolution.
Other than being really damn cool, hypervelocity stars are also useful because they could give us a glimpse at how stars are formed in the heart galaxy, which is cloaked in a halo of dust that obscures all but the brightest stars.

Anonymous asked: You are given two pieces of string and a box of matches. Both strings will burn for exactly thirty minutes each. How will you measure forty-five minutes?

Place the beginning of one string halfway across the other. How do you measure the halfway point? Fold the string and mark the folding point. Then, of course, you light one of the ends and wait for both strings to burn out.

EDIT: Text from grannycat - “Just so you know, they will not burn at the same rate, or evenly, but exactly thirty minutes.” <= This invalidates my answer. I made the implicit assumption that they burn evenly, even if not at the same rate, so that no matter the length or material of each string, the halfway point would be 15 minutes. This would make any T-shape made with the strings an appropriate 45-minute clock, but if they do not burn evenly, things are complicated.. Or simplified, I just don’t know the answer yet. I’m beginning to suspect the fact that you are given a whole box of matches might have something to do with it… Maybe I have to use the box…
