Advise a selection of books for studying of mathematics with 0.
Sirona replied to SeTVP's topic in Mathematics
What country are you in? I use: https://hotmaths.cambridge.edu.au/ https://hotmaths.cambridge.edu.au/ http://freefallmathematics.com/ I find these sites an excellent teaching and learning tool to supplement my own personal teaching resources. If you're a student, your school may have purchased a subscription to a site like Mathletics and you may be able to get a free student account. I like this site in particular because I can add my students to my virtual class and assign courses straight from the syllabus. For example, I can select the Cambridge Maths textbooks for the NSW Australian Curriculum (this is just what I use though and there are many different courses). I can assign them whole units or just topic tests and I can view all their results from my account and track their progress. Both are paid subscriptions and I am not sure of the cost because I have free access through my faculty but I think they are both invaluable. You can also print free ebooks and exam revision booklets for all different age levels. What level are you looking for? Can you give us more information so we can better direct you to some online resources? -
Psychoanalysis is pseudoscience; it is not falsifiable and therefore not scientific because you cannot test hidden psychological states and any knowledge gained is going to be just a prediction.

I am finally getting better, once they removed some hardware they accidentally left in my neck!

I guess 'tidy as you go' applies to surgeons as well as chefs. That sounds awful and frankly, quite scary. It's been a long and painful journey but at least you're on the mend! Hopefully it hasn't taken the cheeriness about you that everyone loves!

AI generated encryption independent of human feedback.
Sirona replied to koti's topic in Science News
They might be able to use the data they collect to expand on human encryption/decryption also. I think it was more of a thought experiment than anything else. -
I'll be sure to steer clear of you then; I'm wary of beguiling men.

It's not surprising and being a spectrum disorder, it can be difficult to diagnose, especially if it's mild. I'm sorry that you're offended by the term because that was not my intent; I don't believe the term is derogatory or offensive and if used in the right context with the appropriate tone it can be affectionate. Since it's easy to misinterpret tone and intent through text, I can appreciate your sentiment and will avoid using the term online.

I do not believe it's specific to my job; there are few occupations where you would not be required to effectively communicate with others. Although, I do agree that generally people are less tolerant of those who are not not linguistically inclined, especially in the workforce because it is competitive. For example, being an effective communicator can save time because there is less of a chance of developing a misunderstanding and no time is wasted on following up or translating; in a lot of cases, time is money. Not only does it interfere with productivity but it can also portray a negative image of the company when dealing with colleagues and/or customers because eloquence is correlated with professionalism. Therefore, I would say that clear communication is just as important in the corporate world (particularly the private sector) for career progression than it is for us educators.

AI generated encryption independent of human feedback.
Sirona replied to koti's topic in Science News
This is not a better method of encryption than what we have now, but it is a very interesting project. The flaw is in assuming that although C couldn't break A and B's code, that the NSA for example with their top cryptographers couldn't break it. It would be interesting to see if the AI is able to decrypt codes written by humans. -
The primary purpose of language is to communicate and I believe as long as they are effectively able to convey their thoughts and be understood, then it is not particularly concerning if they have not constructed a grammatically correct response. I am currently teaching a small group of gifted children maths and several of the boys are recent migrants who have come from and Intensive English Center and still struggle with reading, writing and speaking. However, they are very good at math and able to clearly communicate their mathematical reasoning which they cannot do in written or spoken English well. If I were to judge them based on their spelling, grammar and punctuation, then I would be grossly underestimating their intelligence and ability. Back when the primary purpose of English in schools was to teach literacy, almost everyone in Australia that went through the state school system could write accurately and concisely, however, the literacy standards have significantly declined even among Australian born children. I think it's more important to look beyond the spelling, grammar and punctuation and analyse their ideas. Also, if you say something that is just completely wrong, then you're not going to fool or persuade anyone just by your language skills.

I would be inclined to think that he has Asperger's Syndrome because what you describe is consistent with what I have experienced working with Aspies. Unfortunately, your negative perception is common and Asperger's is often misdiagnosed as Narcissistic Personality Disorder (NPD). In my experience with high functioning Autism Spectrum children, they often display qualities similar to NPD such as limited display of empathy, lack of or poor self-awareness, inability or difficulty in reciprocating emotions, objectifying other people, vanity/pride and difficulty in forming connections; these traits are also consistent with NPD. I have taught a student in maths who had ASD and he would refuse to work in class and when I sought clarification from him, he would reply with 'I know everything and you can't teach me anything that I don't already know; this class is boring because I am smarter than everyone.' It can be difficult dealing with someone who can even at times be condescending, or at the very least, draining to listen to with their constant self-praise, however, it is important to understand that they only seem unsympathetic and/or conceited because they lack the appropriate social reactions to others emotions, not because they don't have empathy. It is important that you avoid creating a stressful environment because they can become overwhelmed which can result in them appearing selfish and/or uncaring, however, this is only because they become withdrawn. The fact that he drives home for two hours to have lunch also is a signal that he has more than a 'superiority complex' as Doc suggested; unusual eating habits are also consistent with ASD and they can be pedantic about food. Perhaps he goes home to eat because he only eats something very specific which he cannot prepare or eat at work. As I mentioned earlier, I cannot be certain given the brief information that was provided, but it would not be unlikely that he has ASD given his personal habits and behaviour.

How much more healthy is brown pasta compared to white pasta?
Sirona replied to james_pain's topic in The Lounge
As far as I know, there isn't. High protein, low carbohydrate diets have been fashionable in Australia in the last few years and I believe David Gillespie's 'Sweet Poison' heightened the sugar anxiety. For the majority of people, the only factors involved in successful weight loss and maintenance is going to be through calorie control and exercise. The problem with sugar is that it's calorific but not nutritious, so you're essentially eating 'empty calories' and not feeling satiated. For some people, especially those who are insulin resistant or diabetic, it increases hunger because it raises insulin levels. However, complex carbohydrates, especially bread, cereal and pasta also contain fat and protein, along with various vitamins and minerals, unlike refined sugar. Therefore, they are not 'empty' calories and will keep you satiated if they are low GI. Although, if you consume less calories than you burn, then you're going to lose weight regardless of what you eat. It is important to have a healthy relationship with food too though. Eliminating whole food groups will most likely lead to vitamin and mineral deficiencies, poor concentration and performance and increased cravings and appetite problems. It is better to fill up on healthy whole foods such as meat, whole grains and fruits and vegetables first, then have the small slice of ice cream or sweet biscuit if you have room. Food for most of us is now so abundant and there are many cheap, low nutritional, processed and calorific food available to us and it's causing an obesity epidemic and it is also impacting the environment because people are eating more and wasting more. I personally think it is important to buy high quality and sustainable fresh produce but to purchase less of it. Avoid buying in bulk and shop more frequently so you do not overestimate how much you need. -

does keeping a journal really help?
Sirona replied to Lyudmilascience's topic in Psychiatry and Psychology
I agree with Karma on this one. I know in Australia, some psychologists will bulk-bill and your local GP is your best port of call to lead you in the right direction. There are a lot of support groups around also that offer free group counselling and support, often led by professional psychologists or students. Perhaps it might be beneficial to have contact with others who are experiencing the same problems as you are. The support will certainly help with feeling less alone and you may learn some useful coping mechanisms. At the very least, you should be able to find someone who is willing to listen and from experience, that goes a long way. On the topic of keeping a personal journal, this is going to depend on the individual; some may find it beneficial, others might not. It is important to do what you know works for you and if you have not had success with writing down your thoughts in the past, then my advice would be to find another outlet. Since I am Australian, the services I could direct you to are not going to be very useful. However, I know public hospitals here usually have free counselling services, however, there are long waiting lists usually. -
It is so difficult to communicate online because it often leads to people misunderstanding your tone and mood. It's a fundamental flaw of mine to respond first emotionally and unfortunately I am too sensitive and emotional. After sleeping on it, I do see a lot of validity in your points, Zapatos. These sort of stories elicit such a strong emotional response from one and it's difficult to be logical when faced with a tragedy involving a child and an animal. I certainly can understand your points. Thank you iNow for broaching the topic logically.
-
I can really empathise with you here, while I am not a parent, I have worked with children with additional needs and this is an area where everyone will question your methods and your ability to do a job. I can't begin to understand how painful it must be for you to feel that your methods are doubted. I unfortunately don't have much of a suggestion and perhaps you have tried this. But could your child have a lunch order? If the canteen has a freshly cooked option? Again I am not sure if this is feasible because he may like only a particular brand. Perhaps you could speak to the school canteen staff?

I agree, Phi. A big part of visiting the zoo is so that you can see animals in a simulated natural habitat and seeing them without a major obstruction is important. Do not misinterpret me, I am not suggesting that public safety should be compromised to improve people's experience, but obviously this is all considered before the construction stage because not only do they have an ethical obligation, but they also want to avoid legal action and negative media attention. Unless the fence was faulty and they could prove this, I believe the negligence lies with the parents. I understand that it's very difficult to watch your child 100% of the time, but one would assume you would not take your child to a public place where there were was reasonable doubt about their safety; as a parent, you know your child the best. If you know that your child has a tendency to climb things, then one would assume it would be common sense not to take your child to the zoo until they've learned to not do this when there is danger present. Children learn at different paces and some children take more time to learn certain things such as acceptable behaviour for different situations. No one will know better than the parent what their child knows and understands as acceptable and unacceptable behaviour in various situations. The zoo can do the best they can to avoid tragedies like this, but ultimately, they cannot be held responsible for every tragedy which happens on their property, unless they were negligent in the construction and maintenance. I don't know enough about the fence construction to comment but since the OP has not suggested there was a known defect with the fence, then I would say the parent is negligible. I understand it's difficult for parents to accept that level of responsibility but ultimately, these are the considerations you need to make when you decide to have a child. It's unfair for businesses to be liable when it's just impossible for them to eliminate all the risks that could lead to an accident; tragedies and accidents do happen.
-
This is a very sad and unfortunate situation and while fault is not easily established in this case, if I had to assign it, I would classify it as parental negligence. It's impossible for a zoo to make the environment 100% safe and unfortunately, these sort of accidents happen, although it is rare. When you decide to become a parent, I believe you're ultimately responsible for the well being of your child; zoos have an ethical responsibility to provide a safe environment but it's impossible to eliminate every risk. As a parent, you need to assess the potential risks and have a plan to minimise the risk. It is intimately your responsibility that you teach your child the correct behaviour for different environments because this is not common sense to them at this age; it needs to be taught. If you have not taught your child not to wonder off in a public space and they get lost, then the parent is liable; this is not so different because as Phi said, this child was not taught to not climb fences. It may be very difficult for a parent to accept they were negligent in this case because it is so traumatic and emotional, but that does not make them exempt from fault.

This unhappiness and insecurity have nothing to do with your appearance; there is absolutely nothing wrong with small breasts. It's only a problem if you see it as one. What sort of men are going to be attracted to unnatural implants? Not the sort I'd personally be interested in. One day you'll have more to worry about other than a flat chest, such as greying hair and wrinkles. If it's not one thing, then it's just another so don't fall down this spiral about wanting to be perfect physically. As I said before, good physical and mental health is attractive and it is possible that men turning you down has more to do with low self esteem than small breasts. If you're looking for love, then you don't want your selection pool to consist of superficial men. I used to be overweight as a teenager and lost a great deal of weight and even though I attract much more attention from now being fit, the quality of men I attracted when overweight was by far better. Although I lost weight in a healthy way and haven't considered surgery, I know what it's like to have low confidence and this attitude keeps creating more to be insecure about; you're never satisfied. Most men aren't looking for idealised beauty but it's our perception from the world around us (media mostly) that shape our opinions on how we want to look.

Thanks, I am thinking of buying a PC for gaming though because I'm too limited with what I can play on a Mac. Has Fraps always worked on Mac? I thought it wasn't compatible.

The Science community here seems to be consistent with other communities I've been apart of online; essentially they're just people and have similar goals and motivations. Some members are absolutely lovely people who genuinely want to educate and continue to learn, they're open and willing to accept you as a friend regardless of your reputation and time here; they give you a chance. Others are polite, informative but distant. Few seem to be disrespectful, others have egos, some are full of humility. I haven't seen anything that has surprised me in terms of personality/character.
-
I'm not certain why you've asked this question and it's not my place to pry or attempt to influence others choices. Just please be well informed before you make such a big decision and remember, people can be attractive in many different ways and imperfections give you character and they're what make you unique. Be confident because that's what is really attractive; people will find any reason to bring you down if that's their intention. I'm not denying that people aren't shallow and judgemental but they are perceptive to your weaknesses, so don't make vanity and insecurity a weakness.

Forgive me if I appear to be blunt because while I do appreciate your concern and compassion towards others, I don't feel you're at all logical. I don't quite understand why you don't believe marine engineers build boats so they're as safe as possible. Obviously boating accidents still do happen but that's mostly due to a sudden and unpredictable change in weather conditions. If you read up on maritime archaeology, you'll see how much boat design has improved. Also, there are already existing devices which make it much more likely to survive a boating accident such as floatation devices, gps, navigation lights, visual distress signals, horns, fire extinguishers, engine spare parts, anchor, rope, etc. You need to take personal responsibility too; data suggests that many leisure boating accidents occur as a result of intoxication. Drowning is the most common cause of boating deaths and statistics show that less than 25% of people wore a life jacket in 2003. Personally, it seems people taking personal responsibility and being accountable is more important than this lung pump you speak of which I am still not sure how you would implement since you didn't explain it. Again, what is the relevance of the sea analogy?
-
I don't understand your sea analogy; are you suggesting that intervention is needed to avoid fatal accidents? While it's possible to minimise your risks, it's ultimately impossible to be able to account for every possible disaster and 'intervene'. Your point is not entirely clear and I'm not certain of what you want to discuss. You're obviously an optimistic person, which is fantastic, however, you have only identified what you believe to be a problem in several posts (along the lines of needing to intervene to stop some catastrophic disaster which you believe is happening) but what are your suggestions?

Rupert Sheldrake theory of morphic resonace
Sirona replied to RomeViharo's topic in Evolution, Morphology and Exobiology
Test experiment results do not support his theory and if you can't prove it, then the default position is to be skeptical. As fascinating as parapsychology seems, the great majority of scientists see it as pseudoscience. People want there to be truth behind psychic phenomena, but that doesn't mean there is; or more accurately, it hasn't been verified. -
